Abstract

The present invention belongs to the field of display technology, and provides a touch panel and a display device, which can solve the problem of low sensitivity, complicated wiring, and high power consumption existing in the existing touch panel. The touch panel of the invention includes a substrate and a touch control layer provided on the substrate, the touch control layer comprising a plurality of touch control units, wherein each of the touch control units has a convex part and a concave part, wherein a shape of the convex part of any one of the touch control units matches with a shape of the concave part of a touch control unit adjacent thereto. The sensitivity of the touch panel provided in the present invention is significantly improved compared to the prior art.

First claim

1 . A touch panel, comprising a substrate and a touch control layer provided on the substrate, the touch control layer comprising a plurality of touch control units, wherein each of the touch control units has a convex part and a concave part, wherein a shape of the convex part of any one of the touch control units matches with a shape of the concave part of a touch control unit adjacent thereto.

2 . The touch panel of claim 1 , wherein the touch control layer further comprises an auxiliary touch control unit provided in a peripheral region of the touch control layer, and a shape of the auxiliary touch control unit matches with a shape of the touch control unit also provided in the peripheral region of the touch control layer, such that a shape of the touch control layer corresponds to a shape of a display region of the touch panel.

3 . The touch panel of claim 1 , further comprising a plurality of signal lines, wherein one end of each signal line is connected to one of the touch control units, with the other end connected to a driving chip.

4 . The touch panel of claim 3 , wherein the signal lines and data lines of the touch panel are provided in one layer, and are formed of a same material.

5 . The touch panel of claim 1 , wherein each of the touch control units is time-division multiplexed as a common electrode of the touch panel.

6 . The touch panel of claim 1 , wherein a material of the touch control unit is ITO.

7 . The touch panel of claim 1 , wherein shapes of the plurality of the touch control units include a first shape and a second shape, the first shape and the second shape are alternately provided in both a row direction and a column direction; wherein
a first side and a third side of the first shape are provided opposite to each other, and a second side and a fourth side of the first shape are provided opposite to each other; the first side and the third side of the first shape each has one convex part, and these two convex parts are provided symmetrically; the second side and the fourth side of the first shape each has one concave part, and these two concave parts are provided symmetrically; and a first side and a third side of the second shape are provided opposite to each other, and a second side and a fourth side of the second shape are provided opposite to each other; the first side and the third side of the second shape each has one concave part, and these two concave parts are provided symmetrically; the second side and the fourth side of the second shape each has one convex part, and these two convex parts are provided symmetrically.

8 . The touch panel of claim 7 , wherein the touch control layer further comprises an auxiliary touch control unit provided in a peripheral region of the touch control layer, and a shape of the auxiliary touch control unit matches with a shape of the touch control unit also provided in the peripheral region of the touch control layer, such that a shape of the touch control layer corresponds to a shape of a display region of the touch panel.

9 . The touch panel of claim 7 , further comprising a plurality of signal lines, wherein one end of each signal line is connected to one of the touch control units, with the other end connected to a driving chip.

10 . The touch panel of claim 9 , wherein the signal lines and data lines of the touch panel are provided in a same layer, and are formed of a same material.

11 . The touch panel of claim 7 , wherein each of the touch control units is further time-division multiplexed as a common electrode of the touch panel.

12 . The touch panel of claim 7 , wherein a material of the touch control unit is ITO.

13 . A display device, comprising the touch panel of claim 1 ,

14 . A display device, comprising the touch panel of claim 2 .

15 . A display device, comprising the touch panel of claim 7 .
