Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present disclosure relates to liquid crystal display
technology, and more particularly to a liquid crystal panel and a
liquid crystal device (LCD).
2. Discussion of the Related Art
[0002] LCD panels generally include a color film substrate and an
array substrate opposite to the color film substrate, and wherein a
liquid crystal layer is encapsulated within the space encapsulated
between the two substrates. As the liquid crystal molecules do not
emit lights themselves, a light source is needed for the display
panel to display images. The LCDs may include transmission,
reflective, and transflective LCDs.
[0003] The transmission liquid crystal panel mainly adopt the
backlight source as the light source, wherein the backlight source
is arranged behind the liquid crystal panel. The pixel electrode on
the array substrate may be the transparent electrode operating as a
transmission area, for which the light beams of the backlight
source may pass through the liquid crystal layer so as to display
the images. With respect to the transmission liquid crystal panels,
the light beams passing through the liquid crystal panel are only a
small portion of the light beams emitting by the backlight source,
that is, the utilization rate of the backlight source is not high.
In order to enhance the brightness of the backlight source, the
power consumption of the backlight source may be greatly
increased.
[0004] Regarding the reflective liquid crystal panel, usually, a
front light source or an external light source is adopted. The
array substrate may adopt the reflective electrodes, which are made
by materials such as metal or other materials having good
reflective characteristics, as the transmission area, so as to
reflect the light beams from the front light source or the external
light source. However, the reflective liquid crystal panels reply
on the external light source and thus are not capable of displaying
the images in dark states.
[0005] The transflective liquid crystal panels may be viewed as
combination of the transmission and the reflective panels. On the
array substrates, not only the reflective area, but also the
transmission area are configured thereon. At the same time, the
backlight source and the front source may be adopted at the same
time. As such, the transflective liquid crystal panels may display
bright images in a dark environment, such as indoor, and also may
be adopted in portable electronic devices, such as cellular phones,
digital cameras, palms and so on, so as to operate in outdoor.
However, the light beams emitted by the backlight source are toward
the transmission area and the reflective area. Although the light
beams toward the transmission area may be effectively utilized, but
the light beams toward the reflective area are totally blocked.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] Embodiments of the invention will now be described more
fully hereinafter with reference to the accompanying drawings, in
which embodiments of the invention are shown.
[0025] FIG. 1 is a schematic view of the LCD in accordance with a
first embodiment. As shown in FIG. 1, the LCD 1 includes a liquid
crystal panel 2 and a backlight module 3. The liquid crystal panel
2 and the backlight module 3 are overlapped and assembled to be a
main body. The liquid crystal panel 2 may be, but not limited to,
Thin Film Transistor-Liquid Crystal Display (TFT-LCD). The liquid
crystal panel 2 includes a first substrate 20, a second substrate
21, and a liquid crystal layer 23 between the first substrate 20
and the second substrate 21. In addition, the liquid crystal panel
2 may include a common electrode 24, a pixel electrode 25, a first
polarizer 26, a second polarizer 27, and a metallic reflective
layer 28. The pixel electrode 25 is arranged between the first
substrate 20 and the liquid crystal layer 23. The common electrode
24 is arranged between the second substrate 21 and the liquid
crystal layer 23. The first polarizer 26 is arranged on a first
surface of the first substrate 20. The first surface is one surface
of the first substrate 20 far away from the second substrate 21.
The second polarizer 27 is arranged on a surface of the second
substrate 21 far away from the first substrate 20. The first
substrate 20 may be a TFT substrate, and the second substrate 21
may be a color film substrate. In addition, a color film (not
shown) is arranged between the second substrate 21 and the common
electrode 24. The first polarizer 26 may be a TFT polarizer, and
the second polarizer 27 may a color film polarizer. The metallic
reflective layer 28 is arranged on the surface of the first
substrate 20 far away from the second substrate 21. Preferably, the
metallic reflective layer 28 is arranged on the surface of the
first polarizer 26 far away from the first substrate 20.
[0026] The backlight module 3 includes a backlight source 31 and a
reflective film 32. The reflective film 32 is arranged within the
backlight source 31 for reflecting the light beams emitted from the
backlight source 31. In addition, the reflective film 32 prevents
the light source from leakage, which increases the optical
efficiency. The backlight source 31 includes, but not limited to,
Light Emitting Diode (LED), or Electroluminescence (EL), for
supplying the light source to the liquid crystal panel 2. In
addition, the backlight module 3 may include a light guiding plate,
optical films, plastic frames, and so on (not shown).
[0027] In the embodiment, the first substrate 20 includes
reflective areas 201 and transmission areas 202 that are arranged
in an interleaved manner. Correspondingly, the first polarizer 26,
the pixel electrode 25, the liquid crystal layer 23, the common
electrode 24, and the second substrate 21 respectively corresponds
to a first area and a second area of the reflective areas 201 and
the transmission area 202. The same liquid crystal materials are
adopted in the first area of the liquid crystal layer 23, which
corresponds to the reflective areas 201, and the second area of the
liquid crystal layer 23, which corresponds to the transmission area
202. The pixel electrode 25 includes a first electrode
corresponding to the reflective area 201 and a second electrode
corresponding to the transmission area 202. The first electrode
drives the liquid crystals within the first area, and the second
electrode drives the liquid crystals within the second area. The
first polarizer 26 is arranged on the first surface of the first
substrate 20. The metallic reflective layer 28 is arranged on the
first polarizer 26. Preferably,
[0028] one side of the first polarizer 26 on the first substrate 20
corresponding to the reflective area 201 is coated with the
metallic reflective layer 28, and another side of the first
polarizer 26 on the first substrate 20 corresponding to the
reflective area 201 is not coated with the metallic reflective
layer 28. The metallic reflective layer 28 may be made by metallic
materials such as aluminum or silver. Wherein, the metallic
reflective layer 28 is wedge-shaped. A surface of the metallic
reflective layer 28 facing toward the liquid crystal layer 23 is a
plane, and a surface of the metallic reflective layer 28 facing
away the liquid crystal layer 23 is a slope. In addition, the
thickness of the metallic reflective layer 28 has been gradually
increased along a direction from the transmission area 202 toward
the reflective area 201.
[0029] Both sides of the metallic reflective layer 28 may reflect
the light beams. In the embodiment, the metallic reflective layer
28 reflects first light beams 29 and second light beams 30. The
first light beams 29 are the light beams emitting from the
backlight source 31 and the reflective film 32, entering the slope
of the metallic reflective layer 28, and being reflected by the
slope. The second light beams 30 are the ambient light beams
passing through the second substrate 21 and the liquid crystal
layer 23, entering the plane of the metallic reflective layer 28,
and being reflected by the plane. The first light beams 29 are
reflected by the metallic reflective layer 28 toward the backlight
module 3 such that the light beams emitted from the backlight
source 31 toward the reflective area 201 may be utilized again,
which enhances the utilization rate of the backlight source. In
addition, the metallic reflective layer 28 may reflect the second
light beams 30 such that the second light beams 30 may emit out
from the reflective area 201. As such, the reflective area 201 may
display the images normally. As the metallic reflective layer 28 is
wedge-shaped, the thickness of the metallic reflective layer 28 is
gradually increased along a direction from the transmission area
202 toward the reflective area 201. That is, the metallic
reflective layer 28 is shown as the slope structure, and the
metallic reflective layer 28 inclines toward the transmission area
202. Thus, the light beams emitted from the backlight source 31 and
the reflective film 32 toward the reflective area 201 are reflected
by the metallic reflective layer 28. Afterward, the first light
beams 29 are reflected toward the backlight module 3, and are
reflected toward the transmission area 202 via the reflective film
32 of the backlight module 3. In the end, the first light beams 29
may emit out from the transmission area 202. In this way, the light
beams emitted from the backlight source 31 may be utilized twice,
and the utilization rate and the optical efficiency of the
backlight source may be enhanced, which may reduce the power
consumption of the LCD 1.
[0030] Thus, by arranging the wedge-shaped metallic reflective
layer 28 on one side of the first substrate 20 corresponding to the
reflective area 201, both of the surfaces of the metallic
reflective layer 28 may reflect the light beams. In addition, the
surface of the metallic reflective layer 28 facing toward the
liquid crystal layer 23 is the plane, and the surface of the
metallic reflective layer 28 facing away the liquid crystal layer
23 is the slope. The thickness of the metallic reflective layer 28
has been gradually increased along the direction from the
transmission area 202 toward the reflective area 201. In this way,
the ambient light beams entering the metallic reflective layer 28
via the second substrate 21 and the liquid crystal layer 23 emit
out from the reflective area 201 after being reflected by the
metallic reflective layer 28, which ensures the reflective area 201
may display the images normally. In addition, the light beams from
the backlight source 31 are reflected toward the backlight module 3
by the metallic reflective layer 28 such that the light beams from
the backlight source 31 may be utilized again. Further, as the
metallic reflective layer 28 is wedge-shaped, it can be seen that
the metallic reflective layer 28 inclines toward the transmission
area 202. Thus, the light beams emitted from the backlight source
31 are reflected toward the area of the backlight module 3
corresponding to the transmission area 202. Afterward, the light
beams emit out after being reflected by the reflective film 32. In
this way, the light beams emitted from the backlight source 31 may
be utilized twice, and the utilization rate and the optical
efficiency of the backlight source may be enhanced, which may
reduce the power consumption of the LCD 1.
[0031] FIG. 2 is a schematic view of the LCD in accordance with a
second embodiment. The difference between the first embodiment and
the second embodiment resides in that the first polarizer 26
includes a hollow area arranged corresponding to the reflective
area 201. The metallic reflective layer 28 is directly arranged on
the surface of the second light beams 30 far away from the second
substrate 21 such that the light beams from the backlight source 31
and the reflective film 32 and the first light beams 29 reflected
by the metallic reflective layer 28 may pass through the hollow
area. The light beams, which are, emitted from the backlight source
31 and the reflective film 32 toward the reflective area 201, are
reflected toward the backlight module 3 via the first light beams
29. Afterward, the light beams are reflected by the reflective film
32 such that the light beams may be utilized again, which enhances
the light utilization rate. In addition, as the metallic reflective
layer 28 is wedge-shaped, the first light beams 29 reflected back
by the metallic reflective layer 28 may be reflected toward the
transmission area 202 by the reflective film 32, and then emit out
from the transmission area 202. As such, the light beams of the
backlight source 31 may be utilized twice. In this way, the
utilization rate and the optical efficiency of the light source may
be enhanced, which reduces the power consumption of the display
device. The ambient light may enter the metallic reflective layer
28 via the second substrate 21 and the liquid crystal layer 23, be
reflected by the metallic reflective layer 28, and emit out from
the reflective area 201. This configuration ensures the normal
display of the reflective area 201.
[0032] In one aspect, a liquid crystal panel includes the liquid
crystal panel in the first and the second embodiment.
[0033] In view of the above, the LCD includes the backlight module
and the liquid crystal panel having the first substrate, the second
substrate, and the liquid crystal layer between the first substrate
and the second substrate. The first substrate includes reflective
areas and transmission areas that are arranged in an interleaved
manner. The surface of the first substrate facing away the second
substrate is configured with a metallic reflective layer, which
corresponds to the transmission areas. The metallic reflective
layer is of the wedge-shaped structure. A surface of the metallic
reflective layer facing toward the liquid crystal layer is a plane,
and a surface of the metallic reflective layer facing away the
liquid crystal layer is a slope. In addition, the thickness of the
metallic reflective layer has been gradually increased along a
direction from the transmission area toward the reflective area.
The metallic reflective layer not only may reflect the ambient
lights, but also may control the reflective area to display the
images normally. In addition, the metallic reflective layer may
reflect the light beams emitted from the backlight source toward
the reflective area such that the light beams emit out from the
transmission areas. In this way, the light beams emitted from the
backlight source may be utilized twice, and the utilization rate
and the optical efficiency of the backlight source may be enhanced,
which may reduce the power consumption of the LCD.
[0034] It is believed that the present embodiments and their
advantages will be understood from the foregoing description, and
it will be apparent that various changes may be made thereto
without departing from the spirit and scope of the invention or
sacrificing all of its material advantages, the examples
hereinbefore described merely being preferred or exemplary
embodiments of the invention.
