application.
BACKGROUND
[0002] The present disclosure relates to a field of display
technology, more particularly, to a touch substrate, a display
panel, and a display device.
[0003] In electronic devices such as personal digital assistants
(PDAs), laptops, office automation equipment, medical devices, and
car navigation systems, touch screens have been widely used as an
input means for these displays. There are different technical
directions for the development of touch technology, for example,
resistance direction, capacitive direction, and electromagnetic
direction. The capacitive screen with low cost and excellent user
experience has become the mainstream product.
[0004] The laminated structure of the bridge type touch screen is
complex and can lead to the disadvantages of low transmittance of
the touch screen and the like, thereby affecting the appearance and
the performance of the touch screen. There is an increasing demand
for narrow bezel and borderless technology in the current market.
The single layer technology enables borderless or narrow bezel
technology due to the indium tin oxide (ITO) edge routing.
Therefore, single-layer technology has drawn people's
attention.

problems that the resistance of the electrode block is too large,
equal impedance wiring is difficult to be arranged and the
repeatability is poor, which leads to the difficulty of product
design and the decrease of the final product performance.

[0041] An embodiment of the present disclosure provides a touch
substrate, which includes a substrate 1201 (see FIG. 12) and an
electrode layer 1202 (see FIG. 12) disposed on the substrate. The

electrode 400A may be about 57:61:57:19.
[0061] FIG. 8 is a schematic view showing an electrode layer
according to still another embodiment of the present disclosure. As
shown in FIG. 8, the first electrode 100B includes a plurality of
first sub-electrodes disposed along a lateral direction, the fourth
electrode 400B includes a plurality of fourth sub-electrodes
disposed along the lateral direction, the repeating unit RC-B
includes a plurality of a first repeating unit portions disposed in
the lateral direction and a plurality of second repeating unit
portions disposed in a lateral direction.
[0062] FIG. 9 is a schematic view of an electrode layer according
to another embodiment of the present disclosure. As shown in FIG.
9, in actual operation, an edge of a sub-electrode (e.g., a
triangular shape or a diamond shape) may have a stepped shape.
Also, the shape of the sub-electrode is not strictly in accordance
with the case shown in FIG. 2, which may be generally triangular or
diamond-shaped.
[0063] Embodiments of the present disclosure also provide a display
panel, which includes the touch substrate as described above.
[0064] FIG. 10 shows a schematic view of a display panel according
to one embodiment of the present disclosure. As shown in FIG. 10,
the display panel 2000 may include the touch substrate 1000
described above.
[0065] Embodiments of the present disclosure also provide a display
device including the display panel as described above.
[0066] FIG. 11 shows a schematic view of a display device according
to one embodiment of the present disclosure. As shown in FIG. 11,
the display device 3000 may include the display panel 2000 as
described above.
[0067] The display device may be a display device having a display
function such as a display panel, a display, a television, a
tablet, a cell phone, a navigator, and the like, which is not
limited in the present disclosure.
[0068] The technical solution provided by the embodiments of the
present disclosure can solve the problem that the impedance of the
electrode in the prior art is too large, equal impedance wiring
difficult, and the repeatability is poor. By configuring the
electrode layer on the substrate to include at least two
electrodes, wherein each electrode includes at least one
sub-electrode having an electrode unit array including at least two
columns of electrode units, each column of the electrode unit array
includes at least two electrode units connected in series, and any
two adjacent columns in the electrode unit array are connected in
parallel through a connection component, a design of equal
impedances and equal capacitances between different electrodes can
be realized, the touch experience of products can be improved, the
difficulty and complexity of design and wiring can be reduced, and
the frameless or narrow bezel technology in the touch area can be
realized.
[0069] Having described certain specific embodiments, these
embodiments have been presented by way of example only, and are not
intended to limit the scope of the present disclosure. Indeed, the
novel embodiments described herein may be embodied in various other
forms, furthermore, various omissions, substitutions, and changes
in the form of the embodiments described herein may be made without
departing from the spirit of the disclosure. The accompanying
claims and their equivalents are intended to cover such forms or
modifications as would fall within the scope and spirit of the
disclosure.
