[0031] Specific implementation party
[0032] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.
[0033] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the illustration to another component, these terms are used in this specification only for convenience, such as according to the orientation of the examples described in the drawings. It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.
[0034] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used merely as labels and are not intended to limit the quantity of their objects.
[0035] Display devices have been widely used in various life, learning and work scenarios. The interaction between users and screens is not limited to vision. The touch function is also a direct and efficient interactive experience. The touch function allows users to interact with video content directly without relying on media such as mice, making the experience more comfortable.
[0036] Of course, in order to improve the security of displayed content, the display device will be equipped with an anti-peeping technology, which reduces the viewing angle and compresses the visible space to protect private content. This display device with integrated touch and anti-peeping functions includes a first display panel with an anti-peeping function and a second display panel with a touch function, and the second display panel is arranged on the display side of the first display panel.
[0037] In order to realize the touch function, a touch control layer is generally provided separately, and the touch control layer is provided on the encapsulation layer of the display panel, or an external touch control substrate is provided to realize it, but this will make it difficult to make the second display panel thinner, have poor light transmittance, and make it difficult to make a narrow frame. In order to reduce the thickness of the display panel, the second display panel is set as a fully embedded (Full In Cell, FIC) touch screen. The second electrode provided on the second array substrate can be used to sense the capacitance change during the non-display time to identify the touch. It should be noted that the second electrode can be a common electrode of the second display panel.
[0038] The second display panel is stacked with the first display panel and attached with a ring-shaped adhesive layer (mouth glue), and a gap is formed between the two. Since there is no support in the gap, when a finger touches the display module, the second display panel and the first display panel are squeezed and easily deformed. After the display module is deformed, the gap will be reduced, so that the second electrode for realizing the touch function is close to the first electrode of the first display panel, and the capacitance between the second electrode and the first electrode will change, which will interfere with the touch signal and affect the touch function of the display device.
[0039] Based on this, the present disclosure provides a display module. Figures 1 to 6As shown, the display module includes a first display panel 1, a second display panel 2 and an anti-interference electrode 3. The first display panel 1 includes a first substrate 11 and a first electrode 141. The first substrate 11 is arranged on one side of the first electrode 141; the second display panel 2 includes a second substrate 21 and a second electrode 241. The second substrate 21 is arranged on a side of the first substrate 11 away from the first electrode 141. The second electrode 241 is arranged on a side of the second substrate 21 away from the first substrate 11, and the second electrode 241 includes a plurality of second electrode units 2411; the anti-interference electrode 3 is arranged between the first substrate 11 and the second substrate 21.
[0040] An anti-interference electrode 3 is provided between the first substrate 11 and the second substrate 21. The anti-interference electrode 3 can form a capacitor with the first electrode 141 to shield the interference of the first electrode 141 on the second electrode 241. The anti-interference electrode 3 can fill the gap formed when the first substrate 11 and the second substrate 21 are bonded, and form a support between the first substrate 11 and the second substrate 21 to avoid the change in the distance between the first electrode 141 and the second electrode 241 caused by the deformation of the second display panel 2. The above two aspects reduce the impact on the touch signal of the display device.
[0041] The display module involved in the embodiment of the present disclosure is described in detail below with reference to specific embodiments.
[0042] like Figure 1 and Figure 2 As shown, the display module includes a first display panel 1 and a second display panel 2 stacked in sequence, the first display panel 1 includes a first substrate 11, a first drive circuit layer and a third substrate 15, the first drive circuit layer is arranged on one side of the third substrate 15, the first substrate 11 is arranged on a side of the first drive circuit layer away from the third substrate 15, and a first polarizer layer 16 is arranged on a side of the first substrate 11 away from the third substrate 15. A first buffer layer 12 may also be arranged between the third substrate 15 and the first drive circuit layer.
[0043] A third electrode 143, a first liquid crystal layer 142 and a first electrode 141 are sequentially stacked between the first driving circuit layer and the first substrate 11. The third electrode 143 is disposed on a side of the first driving circuit layer away from the third substrate 15, the first liquid crystal layer 142 is disposed on a side of the third electrode 143 away from the first substrate 11, the first electrode 141 is disposed on a side of the first liquid crystal layer 142 away from the first substrate 11, and the first substrate 11 is disposed on a side of the first electrode 141 away from the third substrate 15.

[0044] The first driving circuit layer includes multiple first thin film transistors 13. Taking the top-gate thin film transistor as an example, in some embodiments of the present disclosure, the first thin film transistor 13 may include a first active layer 131, a first gate insulating layer 132, a second gate 233, a second interlayer dielectric layer 234, a second source 235 and a second drain 236.

[0045] The second gate 233 is arranged on a side of the first gate insulating layer 132 away from the third substrate 15 and is opposite to the first active layer 131, that is, the projection of the second gate 233 on the third substrate 15 is located within the projection range of the first active layer 131 on the third substrate 15. For example, the projection of the second gate 233 on the third substrate 15 coincides with the projection of the channel region of the first active layer 131 on the third substrate 15.
[0046] The thin film transistor also includes a second interlayer dielectric layer 234, which covers the second gate 233 and the first gate insulating layer 132. The second source 235 and the second drain 236 are arranged on the surface of the second interlayer dielectric layer 234 away from the third substrate 15. The second source 235 and the second drain 236 are connected to the first active layer 131. For example, the second source 235 and the second drain 236 are respectively connected to the two doping regions of the corresponding first active layer 131 through vias.
[0047] The first driving circuit layer may further include a first planarization layer 137, and the first planarization layer 137 may be provided as one layer or multiple layers according to different situations. The first planarization layer 137 is provided on the side of the second source electrode 235 and the second drain electrode 236 away from the third substrate 15, and the surface of the first planarization layer 137 away from the third substrate 15 is a plane. The third electrode 143 is provided on the side of the first planarization layer 137 away from the third substrate 15, and is connected to the second drain electrode 236 through a via hole.
[0048] The second display panel 2 includes a second substrate 21, a second drive circuit layer and a fourth substrate 25, wherein the second drive circuit layer is disposed on one side of the second substrate 21, the fourth substrate 25 is disposed on a side of the second drive circuit layer away from the second substrate 21, and a second polarizer layer 26 is disposed on a side of the fourth substrate 25 away from the second substrate 21. A second buffer layer 22 may also be disposed between the second substrate 21 and the second drive circuit layer.
[0049] A fourth electrode 243, an insulating layer 242, a second electrode 241, and a second liquid crystal layer 244 are sequentially stacked between the second driving circuit layer and the fourth substrate 25. The fourth electrode 243 is disposed on the side of the second driving circuit layer away from the second substrate 21 and away from the first substrate 11. The insulating layer 242 is disposed on the side of the fourth electrode 243 away from the second substrate 21. The second electrode 241 is disposed on the side of the insulating layer 242 away from the second substrate 21. The second liquid crystal layer 244 is disposed on the side of the second electrode 241 away from the second substrate 21. The fourth substrate 25 is disposed on the side of the second liquid crystal layer 244 away from the second substrate 21. The fourth electrode 243 is a pixel electrode of the first display panel 1, and the second electrode 241 is a common electrode of the first display panel 1. A second polarizer layer 26 is disposed on the side of the fourth substrate 25 away from the first substrate 11.
[0050] The second driving circuit layer includes a plurality of second thin film transistors 23. Taking a top-gate thin film transistor as an example, in some embodiments of the present disclosure, the second thin film transistor 23 may include a second active layer 231, a second gate insulating layer 232, a second gate 233, a second interlayer dielectric layer 234, a second source 235 and a second drain 236 stacked in sequence. The second active layer 231 is disposed on one side of the second substrate 21. The second gate insulating layer 232 may cover the second active layer 231 and the second substrate 21, and the material of the second gate insulating layer 232 is an insulating material such as silicon oxide.
[0051] The second gate 233 is arranged on a side of the second gate insulating layer 232 away from the second substrate 21 and is opposite to the second active layer 231, that is, the projection of the second gate 233 on the second substrate 21 is located within the projection range of the second active layer 231 on the second substrate 21. For example, the projection of the second gate 233 on the second substrate 21 coincides with the projection of the channel region of the second active layer 231 on the second substrate 21.
[0052] The thin film transistor also includes a second interlayer dielectric layer 234, which covers the second gate 233 and the second gate insulating layer 232. The second source 235 and the second drain 236 are arranged on the surface of the second interlayer dielectric layer 234 away from the second substrate 21. The second source 235 and the second drain 236 are connected to the second active layer 231. For example, the second source 235 and the second drain 236 are respectively connected to the two doping regions of the corresponding second active layer 231 through vias.
[0053] The second driving circuit layer may further include a second planarization layer 237, and the second planarization layer 237 may be provided as one layer or multiple layers according to different situations. The second planarization layer 237 is provided on the side of the second source electrode 235 and the second drain electrode 236 away from the second substrate 21, and the surface of the second planarization layer 237 away from the second substrate 21 is a plane. The fourth electrode 243 is connected to the second drain electrode 236 through a via hole on the second planarization layer 237. In other embodiments, the structure of the second display panel 2 may also be provided to be the same as that of the first display panel 1.
[0054] When the first display panel 1 is not powered on, the first display panel 1 has no effect on the backlight, and the light is normally emitted through the second display panel 2. At this time, the display module is in a sharing state. When the first display panel 1 is powered on, the polarization direction of the light with an oblique viewing angle changes when passing through the first display panel 1. The direction of the polarized light is not parallel to the emission direction of the second polarizing layer, and it cannot pass through the second display panel 2. The light from the side viewing angle of the second display panel 2 is shielded, and the display module is in an anti-peeping state.
[0055] The second electrode 241 includes a plurality of second electrode units 2411. The controller of the second display panel 2 is provided with a non-display time. During the non-display time, the touch is identified by sensing the capacitance change through the second electrode unit 2411. When a finger touches the surface of the second display panel 2, the finger forms a capacitance with the second electrode unit 2411. The high-frequency signal identifies the capacitance change between the second electrode units 2411 and identifies the touch position of the finger through analog-to-digital conversion.
[0056] An adhesive layer and an anti-interference electrode 3 are provided between the first polarizer layer 16 and the second substrate 21. The adhesive layer is connected to the first polarizer layer 16 and the second substrate 21 respectively. The adhesive layer 4 can be set as an annular structure, and the annular shape can be a continuous and closed strip segment to prevent dust from entering between the first display panel 1 and the second display panel 2 and affecting the display effect. When the adhesive layer 4 is set as a continuous and closed strip segment, the annular structure can be a rectangular circle or a circular circle. The anti-interference electrode 3 is arranged in the annular area surrounded by the adhesive layer, and the anti-interference electrode 3 is arranged on the side of the second substrate 21 close to the first substrate 11. While the anti-interference electrode 3 forms a support between the first display panel 1 and the second display panel 2, it can effectively shield the interference of the first electrode 141 on the second electrode 241.
[0057] The anti-interference electrode 3 can be set as a whole layer of transparent conductive layer, and the material of the transparent conductive layer can be indium tin oxide (ITO). The introduction of a whole layer of anti-interference electrode 3 will cause a decrease in screen brightness. Therefore, the anti-interference electrode 3 can be patterned and designed, and the anti-interference electrode 3 includes a plurality of anti-interference units 31, and the orthographic projection of the anti-interference unit 31 on the second substrate 21 is located within the orthographic projection of the second electrode unit 2411 on the second substrate 21. Each anti-interference unit 31 can support each second electrode unit 2411 respectively to prevent the distance between the second electrode unit 2411 and the first electrode 141 from changing, and an opening area can be formed between the anti-interference units 31, and the backlight can pass through the opening area, effectively improving the transmittance of light and improving the visual experience.
[0058] like Figure 3 and Figure 4 As shown, the second electrode unit 2411 can be set as a square, and the touch drive signal line is connected to the second electrode unit 2411 to collect touch signals of different touch points. The second electrode unit 2411 is obtained by dividing the second electrode 241 into blocks. The size of the second electrode unit 2411 is about 4mm×4mm. Figure 3 Taking the second electrode unit 2411 in the middle A position as an example, Figure 4 The ratio of the area of the second electrode unit 2411 to the area of the anti-interference unit 31 is 1:1 to 10:1. Compared with setting the size of the anti-interference unit 31 to be the same as the size of the second electrode unit 2411, the capacitance of the anti-interference unit 31 is reduced by 10 times, which can reduce the capacitance effect between the second electrode unit 2411 and the anti-interference unit 31 and reduce the load of the display module.
[0059] The second display panel 2 may further include a color filter layer 27, which may include a light shielding portion 271, a first color block 272, a second color block 273, and a third color block 274. The light shielding portion 271 is provided with a color block opening, and the first color block 272, the second color block 273, and the third color block 274 are respectively arranged in each color block opening. The backlight passes through the first color block 272 to form a first sub-pixel, the backlight passes through the second color block 273 to form a second sub-pixel, and the backlight passes through the third color block 274 to form a third sub-pixel. The first sub-pixel is a blue sub-pixel, the second sub-pixel is a green sub-pixel, and the third sub-pixel is a red sub-pixel.
[0060] Because the blue pixel has the lowest transmittance in the outgoing light, the impact on the display effect is relatively small. Figure 2 and Figure 5The orthographic projection of the anti-interference unit 31 on the second substrate 21 can be located within the orthographic projection of the first color block 272 on the second substrate 21, that is, the orthographic projection of the anti-interference unit 31 on the second substrate 21 is located within the orthographic projection of the first sub-pixel on the second substrate 21, and the area of the anti-interference unit 31 can be 1 / 3 to 1 of the area of the first sub-pixel.
[0061] Combination Figure 2 and Figure 6 The orthographic projection of the anti-interference unit 31 on the second substrate 21 can be located within the orthographic projection of the second color block 273 on the second substrate 21, that is, the orthographic projection of the anti-interference unit 31 on the second substrate 21 is located within the orthographic projection of the second sub-pixel on the second substrate 21. Figure 2 and Figure 7 The orthographic projection of the anti-interference unit 31 on the second substrate 21 can be located within the orthographic projection of the third color block 274 on the second substrate 21, that is, the orthographic projection of the anti-interference unit 31 on the second substrate 21 is located within the orthographic projection of the third sub-pixel on the second substrate 21.
[0062] In this case, the anti-interference electrode 3 can be set as a patterned transparent conductive layer, the patterned transparent conductive layer includes a plurality of transparent conductive blocks, or can be set as a patterned metal conductive layer, the patterned metal conductive layer includes a plurality of metal conductive blocks. Specifically, the shape of the anti-interference unit 31 can be square, and the size of the anti-interference unit 31 is about 50μm×50μm to improve the transmittance of the backlight. It should be noted that the material of the transparent conductive block can be indium tin oxide (ITO). It should be noted that the anti-interference units 31 are not independent of each other, but are connected to each other to form a transparent conductive network to achieve full-surface shielding of the first electrode 141 and the second electrode 241.
[0063] The first display panel 1 further includes a ground pad, and the anti-interference electrode 3 is connected to the ground pad. The ground pad can timely conduct away static electricity on the anti-interference electrode 3 to reduce static electricity accumulation, so that the anti-interference electrode 3 maintains a low potential and ensures the function of the second display panel 2.
