[0031] Hereinafter, some example embodiments will be described in
detail with reference to the accompanying drawings. Regarding the
reference numerals assigned to the elements in the drawings, it
should be noted that the same elements will be designated by the
same reference numerals, wherever possible, even though they are
shown in different drawings. Also, in the description of
embodiments, detailed description of well-known related structures
or functions will be omitted when it is deemed that such
description will cause ambiguous interpretation of the present
disclosure.
[0032] It should be understood, however, that there is no intent to
limit this disclosure to the particular example embodiments
disclosed. On the contrary, example embodiments are to cover all
modifications, equivalents, and alternatives falling within the
scope of the example embodiments. Like numbers refer to like
elements throughout the description of the figures.
[0033] In addition, terms such as first, second, A, B, (a), (b),
and the like may be used herein to describe components. Each of
these terminologies is not used to define an essence, order or
sequence of a corresponding component but used merely to
distinguish the corresponding component from other component(s). It
should be noted that if it is described in the specification that
one component is "connected", "coupled", or "joined" to another
component, a third component may be "connected", "coupled", and
"joined" between the first and second components, although the
first component may be directly connected, coupled or joined to the
second component.
[0034] The terminology used herein is for the purpose of describing
particular embodiments only and is not intended to be limiting. As
used herein, the singular forms "a," "an," and "the," are intended
to include the plural forms as well, unless the context clearly
indicates otherwise. It will be further understood that the terms
"comprises," "comprising," "includes," and/or "including," when
used herein, specify the presence of stated features, integers,
steps, operations, elements, and/or components, but do not preclude
the presence or addition of one or more other features, integers,
steps, operations, elements, components, and/or groups thereof.
[0035] It should also be noted that in some alternative
implementations, the functions/acts noted may occur out of the
order noted in the figures. For example, two figures shown in
succession may in fact be executed substantially concurrently or
may sometimes be executed in the reverse order, depending upon the
functionality/acts involved.
[0036] Various example embodiments will now be described more fully
with reference to the accompanying drawings in which some example
embodiments are shown. In the drawings, the thicknesses of layers
and regions are exaggerated for clarity.
[0037] FIG. 1 illustrates an example of a display device according
to at least one example embodiment.
[0038] Referring to FIG. 1, a display device 100 includes a
backlight unit 110, an optical layer 120, and a panel 130. The
display device 100 refers to a device to display a
three-dimensional (3D) image and thus, any type of device
configured to display an image by applying a power may be employed
as the display device 100. The display device 100 may be
implemented in various systems and computing apparatuses, for
example, a smartphone, a tablet computer, a laptop computer, a
desktop computer, a television (TV), a wearable device, a smart
home system, and a digital information display (DID).
[0039] The backlight unit 110 refers to an apparatus to provide
light to the optical layer 120. For example, the backlight unit 100
may include a light guide plate configured to guide a light source
to generate light and the light generated in the light source.
[0040] The optical layer 120 may transmit a portion of light
emitted from the backlight unit 110 and transfer the portion of the
light to the panel 130.
[0041] The optical layer 120 may include a passive 3D optical
element, for example, a parallax barrier, a lenticular lens, and/or
a prism sheet, and an active 3D optical element, for example, a
liquid crystal barrier and an electro-wetting element. A multi-view
3D scheme may be applied to the optical layer 120 so that slits
included in the optical layer 120 are matched to a pixel included
in the panel 130. That is, each slit in the optical layer 120 may
at least partially align with a single pixel (or subpixel), as
shown in FIG. 4. Alternatively, a pixel mismatching scheme may be
applied to the optical layer 120 regardless of whether the slits
are matched to the pixel. The pixel mismatching scheme may refer to
a scheme in which the slits are not matched to the pixel for
increasing resolution. A detailed structure of the slits based on
the pixel mismatching scheme will be provided with reference to
FIG. 5.
[0042] Selectively transmitted light in the optical layer 120 may
have a property, for example, directivity or a directional nature,
of light emitted from a linear light source.
[0043] The panel 130 refers to an apparatus to display an image
based on an image signal to be input. For example, the panel 130
may include a flat panel display (FPD). Since the panel 130 does
not autonomously radiate, the panel 130 may provide the light
emitted from the backlight unit 110 through the optical layer 120.
The panel 130 may display a 3D image using the provided light. In
this example, the light provided from the optical layer 120 may
have a property of the light emitted from the linear light
source.
[0044] Although FIG. 1 illustrates that the display device 100 has
an arrangement that is structured in order of the back light unit
110, the optical layer 120, and the panel 130, the display device
100 may have an arrangement that is structured in order of the
backlight unit 110, the panel 130, and the optical layer 120.
Repeated descriptions will be omitted for increased clarity and
conciseness because the descriptions provided with reference to
FIGS. 2 through 7 are also applicable to the display device 100
having an arrangement structure in order of the backlight unit 110,
the panel 130, and the optical layer 120.
[0045] FIG. 2 illustrates an example of an optical layer according
to at least one example embodiment.
[0046] Referring to FIG. 2, an optical layer 200 includes slits 210
and a barrier 220.
[0047] Slits 210 refer to areas in which light is transmitted, and
vertically neighboring slits among the slits 210 may be connected
to each other. For example, the slits 210 are provided in a step
structure in which the slits 210 are connected to each other by
overlapping a portion of sides of the vertically neighboring
slits.
[0048] A portion of sides of the vertically neighboring slits among
the slits 210 illustrated in FIG. 2 may overlap in a horizontal
direction so that ends of the slits 210 overlap. A portion of lower
sides (or lower ends) of the vertically neighboring slits may
overlap with a portion of upper sides (or upper ends) of other
slits, so that the slits 210 may be connected to each other based
on the step structure.
[0049] According to at least one example embodiment, a size of the
overlapping portion may be determined based on an angle 211 at
which the step structure tilts and a ratio of a slit width to a
pixel width. For example, the angle 211 may be 12.5 degrees and may
be determined based on a number of viewpoints of a 3D image
displayed on a panel. The ratio of the slit width to the pixel
width may refer to a ratio with respect to a width of a slit to a
width of a pixel included in a panel. For example, a ratio of a
slit width to a pixel width may have a range from 20% to 30%.
[0050] Sizes of the slits 210 may be determined based on a size of
a pixel included in a panel. For example, widths of the slits 210
may be set based on a pixel width of the panel. For example, the
widths of the slits 210 may be set to be narrower than a width of a
subpixel included in the pixel. In addition, heights of the slits
210 may be set to be identical to a pixel height or to exceed the
pixel height.
[0051] The slits 210 are provided regardless of whether the slits
210 are matched to the pixel included in the panel. The slits 210
may be provided to be matched to the pixel or provided not to be
matched to the pixel. Shapes of the slits 210 are determined based
on a shape of the pixel included in the panel. For example, the
shapes of the slits 210 may be determined to be identical to the
shape of the pixel.
[0052] The barrier 220 is provided in a remaining area of the
optical layer 200 excluding the slits 210. Light is not
transmittable through the barrier 220.
[0053] FIG. 3 illustrates another example of an optical layer
according to at least one example embodiment.
[0054] Referring to FIG. 3, an optical layer 200 includes slits 310
and a barrier 320.
[0055] The slits 310 refer to areas in which light is transmitted,
and vertically neighboring slits among the slits 310 may be
connected to each other. The slits 310 are provided in a step
structure in which the slits 310 are connected to each other by
overlapping a portion of sides of the vertically neighboring
slits.
[0056] A portion of sides of the vertically neighboring slits among
the slits 310 illustrated in FIG. 3 may overlap in a vertical
direction so that sides of the slits 310 that are adjacent to the
ends of the slits 310 overlap. For example, a portion of right
sides of the vertically neighboring slits may overlap with a
portion of left sides of other slits, so that the slits 310 may be
connected to each other based on the step structure.
[0057] In this example, a size of the overlapping portion may be
set to be less than 30% of a slit height. Concisely, a size of an
overlapping portion of a right side of a slit overlapping a left
side of another slit may be less than 30% of a slit height.
[0058] The barrier 320 is provided in a remaining area of the
optical layer 300 excluding the slits 310. Light is not
transmittable through the barrier 320.
[0059] FIG. 4 illustrates an example of a size of a slit including
an optical layer according to at least one example embodiment.
[0060] Referring to FIG. 4, a pixel 410 included in a panel and a
slit 420 included in an optical layer are illustrated.
[0061] The pixel 410 includes a plurality of subpixels, for
example, a subpixel R, a subpixel G, and a subpixel B, and a black
matrix provided between the subpixels. A size, for example, a width
and a height, of the pixel 410 may be determined based on the
subpixels and the black matrix.
[0062] The slit 420 refers to an area in which light is transmitted
from the optical layer. A size of the slit 420 may be determined
based on the size of the pixel 410.
[0063] A slit width 421 is determined based on a pixel width 411,
and the slit width 421 may be determined to be narrower than a
width of a subpixel included in the pixel 410. For example, the
slit width 421 may be set to be a width from 20% to 30% of the
pixel width 411 or a width from 70% to 80% of a width of a
subpixel.
[0064] A slit height 422 may be determined based on a pixel height
412. For example, the slit height 422 may be set to be identical to
the pixel height 412 or to exceed the pixel height 412.
[0065] The slit 420 may be provided without an angle of inclination
with the pixel 410. Thus, one side of the slit 420 may be provided
to be parallel to one side of the pixel 410. The slit 420 and the
pixel 410 are provided without an angle of inclination between the
slit 420 and the pixel 410, so that light transmitted to the slit
420 may have a property of light passing through a barrier in a
vertical shape without an angle of inclination.
[0066] FIG. 5 illustrates an example of a slit provided based on
pixel mismatching according to at least one example embodiment.
[0067] Referring to FIG. 5, a slit 510 provided based on
mismatching with respect to a pixel included in a panel is
illustrated.
[0068] The slit 510 is provided regardless of whether the slit 510
is matched to the pixel. Concisely, the slit 510 may be provided to
be matched to the pixel, or not to be matched to the pixel. In a
display device, a distance between an optical layer and a panel may
be a longer distance than a width of the slit 510. For example, the
distance between the optical layer and the panel may be designed to
be a distance from 1 millimeter (mm) to 4 mm, and a width of the
slit 510 may be designed to be a width of approximately 60 ff.
Accordingly, an influence of whether the slit 510 is matched to the
pixel may be insignificant or none for displaying a 3D image.
[0069] FIG. 5 illustrates an example in which the slit 510 is
provided based on mismatching with respect to the pixel. In other
words, the slit 510 may be provided by overlapping two
subpixels.
[0070] FIG. 6 illustrates a still another example of an optical
layer according to at least one example embodiment.
[0071] Referring to FIG. 6, an optical layer 600 includes slits 610
and a barrier 620. The slits 610 illustrated in FIG. 6 may have a
shape "<" (or zigzag shape) based on shapes of pixels included
in a panel.
[0072] A pixel included in the panel may have various shapes
including a rectangular shape. Since shapes of the slits 610
included in the optical layer 600 are determined based on a shape
of the pixel, the slits 610 may also have various shapes including
a rectangular shape.
[0073] The shapes of the slits 610 illustrated in FIG. 6 may be
determined to be identical to the shape "<" of the pixel. Even
when the slits 610 have various shapes, vertically neighboring
slits among the slits 610 may be provided to be connected to each
other. The slits 610 are provided in a step structure in which the
slits 610 are connected to each other by overlapping a portion of
sides of the vertically neighboring slits. For example, sides of
the vertically neighboring slits may overlap in a vertical
direction or a horizontal direction.
[0074] FIG. 7 illustrates another example of a display device
according to at least one example embodiment.
[0075] Referring to FIG. 7, a display device 700 includes a
backlight unit and a panel 740. The display device 700 refers to a
device to display an image and thus, any type of device configured
to display an image by applying a power may be employed as the
display device 700. The backlight unit refers to a device including
at least one of light sources 710 and 720 and a light guide plate
730. The backlight unit may differ from the backlight unit 110
illustrated in FIG. 1.
[0076] The light source 710 may be an edge-type light source 710
and the light source 720 may be a direct-type light source 720. The
edge-type light source 710 may be provided at one side of the light
guide plate 730. Light emitted from the edge-type light source 710
may be guided from the light guide plate 730 and emitted to the
panel 740 by a diffusion pattern 731.
[0077] The direct-type light source 720 may be provided at a lower
portion of the light guide plate 730. Light emitted from the
direct-type light source 720 may be provided to the panel 740 by
passing through the light guide plate 730 regardless of the
diffusion pattern 731.
[0078] For example, when the display device 700 is a device to
selectively display a two-dimensional (2D) image and a 3D image,
the display device 700 may selectively turn ON any one of the
edge-type light source 710 and the direct-type light source 720
according to a type of an image to be displayed. For example, when
the image to be displayed is a 3D image, the edge-type light source
710 may be turned ON and the direct-type light source 720 may be
turned OFF. Conversely, when the image to be displayed is a 2D
image, the edge-type light source 710 may be turned OFF and the
direct-type light source 720 may be turned ON.
[0079] In another example, the display device 700 may be a device
to display a 3D image. In this example, the display device 700 may
include the edge-type light source 710 excluding the direct-type
light source 720.
[0080] The light guide plate 730 may guide light incident from the
at least one of the light sources 710 and 720 to the panel 740.
[0081] When the light incident is emitted from the edge-type light
source 710, the light guide plate 730 may guide the light incident
based on a total reflection condition in the light guide plate 730.
When the light guided by the light guide plate 730 reaches the
diffusion pattern 731 disposed at a lower side of the light guide
plate 730, an angle at which the light is processed may be changed.
When light of which the process angle is changed does not satisfy
the total reflection condition, the light may be emitted to the
panel 740. The light emitted from the light guide plate 730 based
on the diffusion pattern 731 may have a property, for example,
directivity or a directional nature, of light emitted from a linear
light source.
[0082] The diffusion pattern 731 includes a plurality of pattern
elements. Vertically neighboring pattern elements from among the
pattern elements may be connected to each other. The pattern
elements may be connected to each other by overlapping a portion of
sides of the vertically neighboring pattern elements. For example,
the portion of sides of the vertically neighboring pattern elements
may overlap in a vertical direction or a horizontal direction.
[0083] Sizes of the pattern elements are determined based on a size
of a pixel included in the panel 740. For example, widths of the
pattern elements are determined based on a pixel width. In one
example, the widths of the pattern elements may be set to be
narrower than a width of a subpixel included in the pixel. In
addition, heights of the pattern elements may be set to be
identical to a pixel height or to exceed the pixel height.
[0084] The pattern elements are provided regardless of whether the
pattern elements are matched to the pixel. The pattern elements may
be provided to be matched to the pixel or provided not to be
matched to the pixel. Also, shapes of the pattern elements may be
determined based on a shape of the pixel included in the panel 740.
For example, the shapes of the pattern elements may be determined
to be identical to the shape of the pixel.
[0085] Repeated descriptions will be omitted for increased clarity
and conciseness because the descriptions on the slits provided with
reference to FIGS. 1 through 6 are also applicable to the pattern
elements included in the diffusion pattern 731.
[0086] In another example, when the light incident is emitted from
the direct-type light source 720, the light guide plate 730 may
guide the incident light to the panel 740. The light incident from
the direct-type light source 720 may be emitted to the panel 740
regardless of the diffusion pattern 731.
[0087] The panel 740 may display a 2D image or a 3D image using
light provided from the light guide plate 730. When light generated
from the edge-type light source 710 is provided to the panel 740
through the light guide plate 730, the panel 740 may display the 3D
image. Conversely, when light generated from the direct-type light
source 720 is provided to the panel 740 through the light guide
plate 730, the panel 740 may display the 2D image.
[0088] According to example embodiments, it is possible to
effectively reduce a Moire phenomenon and crosstalk occurring in a
3D display device by generating a linear light source similar to a
square wave using an optical layer having a step structure in which
vertically neighboring slits are connected to each other.
[0089] Also, according to example embodiments, it is possible to
mitigate (or alternatively, prevent) deterioration in image quality
of a 2D image displayed on the 3D display device, without providing
an optical layer on a front surface of a panel, based on an
architecture arrangement structure in order of a backlight unit, an
optical layer, and a panel.
[0090] Also, according to example embodiments, it is possible to
mitigate (or alternatively, prevent) a Moire phenomenon occurring
in a display device by setting a slit width to be narrower than a
subpixel width.
[0091] Also, according to an example embodiment, it is possible to
decrease crosstalk by designing a slit based on a pixel
phenomenon.
[0092] The units and/or modules described herein may be implemented
using hardware components and software components. For example, the
hardware components may include microphones, amplifiers, band-pass
filters, audio to digital convertors, and processing devices. A
processing device may be implemented using one or more hardware
device configured to carry out and/or execute program code by
performing arithmetical, logical, and input/output operations. The
processing device(s) may include a processor, a controller and an
arithmetic logic unit, a digital signal processor, a microcomputer,
a field programmable array, a programmable logic unit, a
microprocessor or any other device capable of responding to and
executing instructions in a defined manner. The processing device
may run an operating system (OS) and one or more software
applications that run on the OS. The processing device also may
access, store, manipulate, process, and create data in response to
execution of the software. For purpose of simplicity, the
description of a processing device is used as singular; however,
one skilled in the art will appreciated that a processing device
may include multiple processing elements and multiple types of
processing elements. For example, a processing device may include
multiple processors or a processor and a controller. In addition,
different processing configurations are possible, such as parallel
processors.
[0093] The software may include a computer program, a piece of
code, an instruction, or some combination thereof, to independently
or collectively instruct and/or configure the processing device to
operate as desired, thereby transforming the processing device into
a special purpose processor. Software and data may be embodied
permanently or temporarily in any type of machine, component,
physical or virtual equipment, computer storage medium or device,
or in a propagated signal wave capable of providing instructions or
data to or being interpreted by the processing device. The software
also may be distributed over network coupled computer systems so
that the software is stored and executed in a distributed fashion.
The software and data may be stored by one or more non-transitory
computer readable recording mediums.
[0094] The methods according to the above-described example
embodiments may be recorded in non-transitory computer-readable
media including program instructions to implement various
operations of the above-described example embodiments. The media
may also include, alone or in combination with the program
instructions, data files, data structures, and the like. The
program instructions recorded on the media may be those specially
designed and constructed for the purposes of example embodiments,
or they may be of the kind well-known and available to those having
skill in the computer software arts. Examples of non-transitory
computer-readable media include magnetic media such as hard disks,
floppy disks, and magnetic tape; optical media such as CD-ROM
discs, DVDs, and/or Blue-ray discs; magneto-optical media such as
optical discs; and hardware devices that are specially configured
to store and perform program instructions, such as read-only memory
(ROM), random access memory (RAM), flash memory (e.g., USB flash
drives, memory cards, memory sticks, etc.), and the like. Examples
of program instructions include both machine code, such as produced
by a compiler, and files containing higher level code that may be
executed by the computer using an interpreter. The above-described
devices may be configured to act as one or more software modules in
order to perform the operations of the above-described example
embodiments, or vice versa.
[0095] A number of example embodiments have been described above.
Nevertheless, it should be understood that various modifications
may be made to these example embodiments. For example, suitable
results may be achieved if the described techniques are performed
in a different order and/or if components in a described system,
architecture, device, or circuit are combined in a different manner
and/or replaced or supplemented by other components or their
equivalents. Accordingly, other implementations are within the
scope of the following claims.
