Description

Technical Field

[0001] This invention relates to a display panel and a display device, and more particularly to a touch display panel and a display device using the same. Background Technology

[0002] With the development of technology, display devices are widely used in many electronic products, such as mobile phones, tablets, watches, and automobiles.

[0003] For touch display devices, the touch signal lines are connected to the touch electrodes by punching holes. Figure 1 This is a schematic diagram illustrating the punching methods used in existing touch display panels. For example... Figure 1 As shown, existing technologies typically employ a curtain-style perforation method. At the locations where the touch signal line connects to the touch electrode, vias and connection holes (TH) need to be formed in the planarization layer and insulating layer, respectively. Where the touch signal line and touch electrode do not need to connect, only vias are formed in the planarization layer. Furthermore, in existing technologies, the dummy touch signal line also extends to all touch electrodes, and all are perforated using a combination of vias and connection holes. This via-and-connection hole perforation method can prevent the alignment liquid in the display panel from flowing smoothly into the vias due to uneven terrain, affecting the alignment of the liquid crystal layer at these locations. During display, the liquid crystal layer cannot rotate properly, resulting in a curtain-like shadow. The shape and distribution of this shadow correspond to the perforation locations in the touch electrode.

[0004] In addition, in order to meet the needs of active pen touch, the display panel often increases the thickness of the planarization layer during the design stage to reduce capacitance, which makes it more difficult for the alignment liquid to flow into the through-hole, exacerbating the formation of curtain-like shadows.

[0005] Therefore, how to provide a new perforation method that can reduce or avoid the formation of curtain-like shadows and improve the display quality of touch display panels and display devices is one of the problems that needs to be solved. Summary of the Invention

[0006] Embodiments of the present invention provide a touch display panel and display device that employ a new perforation method to reduce or avoid the formation of curtain-like shadows, thereby improving the display quality of the touch display panel and display device.

[0046] The structural and working principles of the present invention will be described in detail below with reference to the accompanying drawings:

[0047] Figure 2 This is a schematic diagram of the structure of a touch display panel according to an embodiment of the present invention. Figure 3 yes Figure 1 A schematic diagram of a portion of the structure of a row of touch electrodes. (See diagram below.) Figure 2 , Figure 3 As shown, the touch display panel 100 of the present invention includes a substrate 101, a touch electrode array, and multiple touch signal lines 103. The touch electrode array is disposed on the substrate 101, and the touch electrode array has N touch electrode columns TP1...TPn, TPn+1... along a first direction D1. Each touch electrode column has M touch electrodes along a second direction D2, where M and N are positive integers. The multiple touch signal lines 103 extend along the second direction D2.

[0048] Taking one column of the touch electrode array, such as touch electrode column TPn (1≤n≤N), as an example, Figure 3 As shown, the touch electrode array TPn includes a first touch electrode 1021 and a second touch electrode 1022, which are arranged adjacent to each other along the second direction D2. The touch electrode array TPn corresponds to the first touch signal line group 103n; that is, the projection of the first touch signal line group 103n onto the substrate 101 corresponds to the touch electrode array TPn. Simultaneously, multiple through holes are provided corresponding to the first touch electrode 1021, defined in this invention as first through holes 104, which are used to electrically connect the first touch electrode 1021 to the first touch signal line group 103n. Multiple through holes are also provided corresponding to the second touch electrode 1022, defined in this invention as second through holes 105, which are used to electrically connect the second touch electrode 1022 to the first touch signal line group 103n.

[0049] All the first through holes 104 corresponding to the first touch electrode 1021 form a first connecting line 106. The first connecting line 106, in general, extends in a trend, such as... Figure 3As shown, the extension trend of the first connecting line 106 can be considered as extending along the third direction D3. All the second through holes 105 corresponding to the second touch electrode 1022 form the second connecting line 107. The extension trend of the second connecting line 107 can be considered as extending along the fourth direction D4. There is a first included angle a1 between the third direction D3 and the first direction D1, and a second included angle a2 between the fourth direction D4 and the first direction D1, wherein 90° < a1 < 180°, 180° < a2 < 270°. Specifically, in this invention, the first included angle a1 refers to the angle rotated when the first direction D1 rotates counterclockwise until it coincides with the third direction D3, and the second included angle a2 refers to the angle rotated when the first direction D1 rotates counterclockwise until it coincides with the fourth direction D4. In one embodiment, the third direction D3 refers to the extension direction of the first through hole 104, starting from the rightmost first through hole 104 shown in the figure and ending at the leftmost first through hole 104 shown in the figure; the fourth direction D4 refers to the extension direction of the second through hole 105, starting from the rightmost second through hole 105 shown in the figure and ending at the leftmost second through hole 105 shown in the figure.

[0050] The touch display panel of this invention has a small number of through holes corresponding to adjacent touch electrodes, and these through holes are arranged in a predetermined manner. Because of the small number of through holes, the impact of uneven terrain on the distribution of the alignment liquid is greatly reduced. Furthermore, even if the liquid crystal alignment at each through hole is affected, the formation of curtain-like shadows can still be greatly reduced or avoided because the through holes are arranged in a predetermined manner, thus improving the quality of the touch display panel.

[0051] For the first through hole 104, all the first through holes 104 are arranged at equal intervals in the second direction D2; or, for the second through hole 105, all the second through holes 105 are arranged at equal intervals in the second direction D2. Normally, the multiple touch signal lines 103 in the first touch signal line group 103n are arranged at equal intervals in the first direction D1. When the first through holes 104 or the second through holes 105 are arranged at equal intervals, the first connecting line 106 formed by the first through holes 104 is linearly distributed, and the second connecting line 107 formed by the second through holes 105 is also linearly distributed.

[0052] Of course, the first through hole 104 or the second through hole 105 can also be arranged at unequal intervals in the second direction D2. Taking two pairs of adjacent second through holes 105 as an example, the two pairs of adjacent second through holes 105 form intervals s1 and s2 respectively, where s1 ≠ s2. Further, for example, s1 > s2. In this case, the second connecting line 107 is not a straight line. When multiple intervals s1 and s2 are formed, the second connecting line 107 is a broken line or a curve. Similarly, for the first connecting line 106 of the first through hole 104, the first connecting line 106 can also be a broken line or a curve.

[0053] The first through hole 104 or the second through hole 105 may be arranged in a manner with equal spacing, or in a manner with unequal spacing, or in a manner with some equal spacing and some unequal spacing. This invention is not limited to these arrangements.

[0054] For the touch electrode array TPn, the touch electrode array TPn includes multiple repeating first touch electrodes 1021 and second touch electrodes 1022. Since the first through hole 104 extends along the third direction D3 and the second through hole 105 extends along the fourth direction D4, the connection line formed by the through holes in all the touch electrodes 102 of the touch electrode array TPn is a continuous "S" shape.

[0055] By setting up "S"-shaped through holes, the new arrangement of through holes can reduce or avoid the curtain-like shadow caused by the high density and regular arrangement of each through hole in the prior art, which affects the regular alignment of the liquid crystal layer, thus improving the display quality of the touch display panel.

[0056] In one embodiment, the bending amplitude of the "S" shape in the second direction D2 can gradually increase or gradually decrease.

[0057] It should be noted that, in this invention, the touch display panel 100 has opposing first and second ends (not shown in the figure) along the second direction D2. The first end is provided with a bonding pad (not shown in the figure) for connecting with multiple touch signal lines 103. For example, the first end is located at... Figure 2 The lower end of the touch display panel shown, the second end is located at... Figure 2 The upper end of the touch display panel shown has a connecting pad for providing touch signals to multiple touch signal lines 103, and the multiple touch signal lines 103 extend from the first end toward the second end along the second direction D2.

[0058] In one embodiment, a bonding pad is used to connect a driver chip (IC) or a chip-on-film (COF) film. After the driver chip or COF film provides a touch signal, it is transmitted to multiple touch signal lines 103 via the bonding pad.

[0059] In one embodiment, each touch signal line 103 in the first touch signal line group 103n is connected to the first touch electrode 1021 through a first through hole 104, and each touch signal line 103 is electrically connected to the second touch electrode 1022 through a second through hole 105. The touch electrode column TPn has M touch electrodes 102 along the second direction D2, and the touch signal line group has M touch signal lines 103 along the first direction D1. Taking the first touch electrode 1021 as the m-th touch electrode in the touch electrode column TPn and the second touch electrode as the (m+1)-th touch electrode in the touch electrode column TPn as an example, the first through hole 104 electrically connects the m-th touch signal line to the M-th touch signal line. However, not all of the m-th to M-th touch signal lines extend continuously from the first touch electrode 1021 to the aforementioned connecting pad; only the m-th touch signal line extends continuously from the first touch electrode 1021. The second through-hole 1022 extends to the aforementioned connecting pad to receive touch signals (described in detail below); the second through-hole 1022 is electrically connected to the (m+1)th touch signal line to the Mth touch signal line. Similarly, not all of the (m+1)th to the Mth touch signal lines extend continuously from the second touch electrode 1022 to the aforementioned connecting pad, but only the (m+1)th touch signal line extends continuously from the second touch electrode 1022 to the aforementioned connecting pad to receive touch signals (described in detail below).

[0060] like Figure 3 As shown, Figure 3An exemplary illustration shows a first touch signal line group 103n comprising five touch signal lines 103, which, from left to right as shown in the figure, are the first touch signal line 103 to the fifth touch signal line 103. A first touch electrode 1021 is the first touch electrode, and a second touch electrode 1022 is the second touch electrode. The first touch signal line in the first touch signal line group 103n extends continuously from the second touch electrode 1022 to the first touch electrode 1021 along a second direction D2 to transmit touch signals to the first touch electrode 1021. The remaining touch signal lines in the first touch signal line group 103n, namely the second touch signal line 103 to the fifth touch signal line 103, have an opening 108 along the second direction D2 between the second touch electrode 1022 and the first touch electrode 1021. Therefore, the remaining touch signal lines in the first touch signal line group 103n extend to the first touch electrode 1021 in a discontinuous manner. Within the area corresponding to the touch electrode column where the first touch electrode 1021 is located, the remaining touch signal lines have openings at least partially between adjacent touch electrodes, so that the remaining touch signal lines are not used to transmit touch signals to the first touch electrode 1021. Thus, the first touch electrode 1021 is electrically connected to the first touch signal line 103 to the fifth touch signal line 103 through five through holes, but only the first touch signal line 103 extends continuously to the first touch electrode 1021 to transmit touch signals to the first touch electrode 1021.

[0061] In one embodiment, the second touch electrode 1022 is electrically connected to the second to fifth touch signal lines 103 through four through holes, but only the second touch signal lines 103 extend continuously to the second touch electrode 1022 to transmit touch signals to the second touch electrode 1022. Furthermore, each of the second to fifth touch signal lines 103 between the first touch electrode 1021 and the second touch electrode 1022 has an opening 108. The second touch electrode 1022 and the second touch signal lines 103... The third to fifth touch signal lines 103 between two adjacent touch electrodes arranged in the second direction D2 all have openings, so that the remaining touch signal lines in the first touch signal line group 103n extend to the second touch electrode 1022 in a discontinuous manner. In the region corresponding to the touch electrode column where the first touch electrode 1021 is located, the remaining touch signal lines have openings at least partially between adjacent touch electrodes, so that the remaining touch signal lines are not used to transmit touch signals to the second touch electrode 1022. By analogy, the other touch electrodes 102 in the touch electrode column TPn are electrically connected to the touch signal lines 103 through vias, so that only the corresponding touch signal lines 103 extend continuously to the corresponding touch electrode to transmit touch signals to that touch electrode.

[0062] In this invention, corresponding to the touch electrode array TPn and its corresponding touch signal line group 103n, each touch signal line 103 in the first touch signal line group is connected to the first touch electrode 1021 through at most one first through hole 104; each touch signal line 103 is electrically connected to the second touch electrode 1022 through at most one second through hole 105. Each touch electrode 102 is electrically connected to one touch signal line 103 in the touch signal line group through at most one through hole, and each touch electrode 102 receives touch signals from the connection pad through only one touch signal line 103.

[0063] Figure 4 This is a schematic diagram of a partial area of ​​the adjacent columns of touch electrodes according to an embodiment of the present invention. (Combined with...) Figures 2 to 4 As shown, the touch electrode array of the touch display panel 100 includes adjacent touch electrode columns TPn and TPn+1, and the arrangement of through holes in the touch electrode column TPn is as follows. Figure 3 As mentioned above, this will not be repeated here. Regarding Figure 4 The touch electrode array TPn+1 shown has a via arrangement that is similar to... Figure 3 The through-holes in the touch electrode array TPn shown are arranged in the same way.

[0064] Detailed, such as Figure 4 As shown, the touch electrode array TPn+1 includes a third touch electrode 1023 and a fourth touch electrode 1024 arranged adjacent to each other along the second direction D2. The first touch electrode 1021 in the touch electrode array TPn and the third touch electrode 1023 in the touch electrode array TPn+1 are arranged adjacent to each other along the first direction D1, and the second touch electrode 1022 in the touch electrode array TPn and the fourth touch electrode 1024 in the touch electrode array TPn+1 are arranged adjacent to each other along the first direction D1. The touch electrode array TPn+1 corresponds to the touch signal line group 103n+1, and the projection of the touch signal line group 103n+1 onto the substrate 101 corresponds to the touch electrode array TPn+1.

[0065] The through-hole corresponding to the third touch electrode 1023 is defined as a third through-hole. The third touch electrode 1023 is electrically connected to the touch signal line group 103n+1 through the third through-hole. All third through-holes form a third connecting line, which extends along the fifth direction D5. There is a third included angle a3 between the fifth direction D5 and the first direction D1. The through-hole corresponding to the fourth touch electrode 1024 is defined as a fourth through-hole. The fourth touch electrode 1024 is electrically connected to the touch signal line group 103n+1 through the fourth through-hole. All fourth through-holes form a fourth connecting line, which extends along the sixth direction D6. There is a fourth included angle a4 between the sixth direction and the first direction D1. Wherein, 90° < a3 < 180°, 180° < a4 < 270°.

[0066] Figure 5 This is a schematic diagram of a portion of the structure of adjacent columns of touch electrodes according to another embodiment of the present invention. Figure 5 The illustrated embodiments and Figure 4 The difference between the implementation classes shown is that, Figure 5 The arrangement of the through holes in the touch electrode array TPn+1 is different from that in the touch electrode array TPn. Figure 4 In the middle, the arrangement of through holes in touch electrode array TPn+1 is basically the same as that in touch electrode array TPn. Figure 5 In the above, the arrangement of the through holes in the touch electrode array TPn+1 and TPn can be considered as a mirror image of the touch electrode array TPn+1 along the second direction D2. Where 180° < a3 < 270°, 90° < a4 < 180°

[0067] Of course, for multiple touch electrode columns in a touch display panel, two adjacent touch electrode columns can all be... Figure 4 Arranged as shown, or all in Figure 5 The arrangement shown can also be partially done in the manner indicated. Figure 4 The method and part shown are as follows Figure 5 The arrangement shown is spaced apart and adjacent to each other, but the present invention is not limited thereto.

[0068] In the embodiments of the present invention, the arrangement of the through holes is shown only by way of example. For the present invention, the more irregular and random the arrangement of the through holes in the touch electrode array, the better the effect of avoiding the generation of curtain-like shadows.

[0069] The present invention also provides a display device, including any of the touch display panels described above.

[0070] According to an embodiment of the present invention, by setting the through holes in an "S" shape, the new arrangement of the through holes can reduce or avoid the formation of curtain-like shadows, thereby improving the display quality of the touch display panel and the display device.

[0071] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
