DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the drawings; and "inside" and "outside" refer to the outline of the device.

[0035] The present application provides a display panel 1, such as Figures 1A to 4A As shown, the display panel 1 includes a plurality of pixel groups 10 arranged along a first direction D1, a plurality of signal lines 20 and a touch electrode layer 30, a pixel group 10 includes a plurality of sub-pixels 11 arranged along a second direction D2; a signal line 20 provides a driving signal for each sub-pixel 11 in a pixel group 10; the touch electrode layer 30 includes a plurality of spaced touch electrode blocks 31, and the orthographic projections of the plurality of signal lines 20 on the touch electrode blocks 31 overlap with the touch electrode blocks 31; wherein, the orthographic projection of at least one signal line 20 on the touch electrode layer 30 overlaps with both of the two touch electrode blocks 31 adjacent to each other in the first direction D1, and the second direction D2 is set at an angle to the first direction D1.

[0036] In this embodiment, the display panel 1 may be an embedded touch panel, for example, an LCD panel, an OLED panel, or the like.

[0037] The touch electrode layer 30 of the in-cell touch panel can be time-division multiplexed with the common electrode layer of the LCD panel, or the touch electrode layer 30 can be time-division multiplexed with the cathode of the OLED panel. This application does not impose any limitation on this.

[0038] When the display panel 1 is an LCD panel, the display panel 1 includes a common electrode layer, a pixel electrode layer and a liquid crystal layer. The pixel electrode layer includes a plurality of pixel electrodes, and one pixel electrode is provided corresponding to one sub-pixel 11. The common electrode layer provides a common voltage (VCOM), and the pixel electrode layer provides a pixel voltage. The liquid crystal molecules in the liquid crystal layer are deflected under the action of the electric field formed by the common voltage and the pixel voltage, thereby realizing the brightness control of the display panel 1.

[0039] Among them, time-division multiplexing means that the common electrode layer of the display panel 1 is used in the display stage and the touch stage respectively according to time. In the display stage, the common electrode layer provides a common voltage for the display panel 1. In the touch stage, the common electrode layer is used as a touch electrode layer 30 to receive touch signals and realize the touch function.

[0040] In this embodiment, if Figure 1A As shown, the display panel 1 includes a display area AA and a non-display area NA arranged outside the display area AA. A plurality of sub-pixels 11 are arranged in the display area AA, and the sub-pixels 11 may include red sub-pixels, green sub-pixels, and blue sub-pixels. The display area AA can be used to display images. The non-display area NA may be provided with a driving circuit and a driving chip 13. The driving circuit may be a gate driving circuit 12, and the gate driving circuit 12 is used to provide a scanning signal, etc. to the sub-pixel 11. The driving chip 13 is used to provide a data signal, etc. to the sub-pixel 11. The gate driving circuit 12 may be arranged on opposite sides of the display area AA, and the driving chip 13 may be arranged on the other side of the display area AA, but is not limited thereto.

[0041] In this embodiment, if Figure 1A As shown, the display panel 1 includes a plurality of pixel groups 10 arranged along a first direction D1, and a pixel group 10 includes a plurality of sub-pixels 11 arranged along a second direction D2. The first direction D1 and the second direction D2 may also be interchanged.

[0042] In this embodiment, the extension direction of the signal line 20 is the same as the arrangement direction of the plurality of sub-pixels 11 in the pixel group 10. The signal line 20 is used to provide a driving signal for each sub-pixel 11 in the pixel group 10. The signal line 20 can be a scan line 21, a data line 22, a touch line 23, etc., but is not limited thereto.

[0043] Alternatively, if Figure 1A As shown, the signal line 20 may be a scan line 21 , and the scan line 21 provides a scan signal to each sub-pixel 11 in the pixel group 10 .

[0044] Alternatively, if Figure 1B As shown, the signal line 20 can be a data line 22 or a touch line 23. It should be understood that when the signal line 20 is a data line 22, the driver chip 13 is connected to the data line 22. When the signal line 20 is a touch line 23, the touch chip 50 is electrically connected to the touch line 23. This application is described by taking the signal line 20 as a scan line 21 as an example, which should not be understood as a limitation to this application.

[0045] In this embodiment, if Figure 2 As shown, the touch electrode layer 30 includes a plurality of touch electrode blocks 31, two adjacent touch electrode blocks 31 are arranged at intervals, and one touch electrode block 31 corresponds to a plurality of sub-pixels 11. It should be noted that the touch electrode layer 30 and the signal line 20 are arranged in different layers. The touch electrode layer 30 can be arranged roughly corresponding to the display area AA. Figure 1A and Figure 2 The sub-pixel 11 and the touch electrode block 31 in the figure only illustrate the general structure, and do not represent the actual size relationship between the sub-pixel 11 and the touch electrode block 31.

[0046] Specifically, Figure 3 and Figure 4A As shown, the area of ​​a touch electrode block 31 can be greater than the area of ​​a sub-pixel 11. The area refers to the area of ​​the orthographic projection of each part on the display surface. A touch electrode block 31 corresponds to at least two rows and two columns of sub-pixels 11, and a touch electrode block 31 covers at least two signal lines 20. The touch electrode block 31 can be block-shaped, that is, the size of the touch electrode block 31 in the first direction D1 and the second direction D2 can be roughly the same.

[0047] The shape of the touch electrode may be rectangular, diamond, circular or irregular, which is not limited in the present application.

[0048] The orthographic projection of a signal line 20 on the touch electrode layer 30 overlaps with two adjacent touch electrode blocks 31 in the first direction D1. That is to say, a signal line 20 overlaps with the touch electrode blocks 31 on both sides of the signal line 20 at the same time. When the signal line 20 overlaps with the touch electrode blocks 31, a capacitor is formed. Due to capacitive coupling, a voltage change on the signal line 20 will cause a voltage change on the touch electrode blocks 31. In this embodiment, the coupling amount between the signal line 20 and the touch electrode blocks 31 on each side is reduced, thereby reducing the coupling degree between the signal line 20 and the touch electrode blocks 31, thereby improving the display unevenness of the display panel 1.

[0049] like Figure 1CAs shown, the dotted line represents the coupling amount between the touch electrode block 31 and the signal line 20 in the related art, and the peak value of the waveform is h1. The thick solid line represents the coupling amount between the touch electrode block 31 and the signal line 20 in the embodiment of the present application, and the peak value of the waveform is h2. Since in the embodiment of the present application, the coupling amount between the signal line 20 and the touch electrode block 31 on each side is reduced, h2

[0050] In the present embodiment, the material of the touch electrode layer 30 may be a transparent conductive material. The transparent conductive material may include ITO (indium tin oxide), IZO (indium zinc oxide), IZTO (indium zinc tin oxide), IAZO (indium aluminum zinc oxide), IGZO (indium gallium zinc oxide), IGTO (indium gallium tin oxide), AZO (aluminum zinc oxide), ATO (antimony tin oxide), IGZTO (indium gallium zinc tin oxide), IGO (indium gallium oxide), InO (indium oxide), etc.

[0051] In this embodiment, the second direction D2 is arranged at an angle with the first direction D1 , and the angle may be an acute angle or a right angle, which is not limited in the present application.

[0052] In the display panel 1 of the present application, Figures 2 to 4A As shown, the edge of the touch electrode block 31 is provided with a plurality of protrusions 31a arranged at intervals along the second direction D2, one protrusion 31a is arranged corresponding to at least one sub-pixel 11, the protrusions 31a of two adjacent touch electrode blocks 31 are arranged alternately, and the orthographic projection of at least one signal line 20 on the touch electrode layer 30 overlaps with any protrusion 31a of two adjacent touch electrode blocks 31 in the first direction D1.

[0053] In this embodiment, a plurality of protrusions 31a are provided at the edge of the touch electrode block 31, and the arrangement direction of the protrusions 31a is the same as the extension direction of the signal line 20. One protrusion 31a is provided corresponding to at least one sub-pixel 11. Optionally, one protrusion 31a corresponds to one, two or more sub-pixels 11 in a column; or one protrusion 31a corresponds to one, two or more sub-pixels 11 in a row. The number of sub-pixels 11 corresponding to two adjacent protrusions 31a may be the same or different.

[0054] In this embodiment, if Figure 4A As shown, the protrusions 31a of two touch electrode blocks 31 adjacent to each other along the first direction D1 are arranged alternately. That is to say, grooves can be arranged between the protrusions 31a, and the protrusion 31a of one touch electrode block 31 is correspondingly engaged with the groove of another touch electrode block 31.​

[0055] In this embodiment, the orthographic projection of at least one signal line 20 on the touch electrode layer 30 overlaps with any protrusion 31a of two adjacent touch electrode blocks 31 in the first direction D1. Since the signal line 20 is arranged along the second direction D2, the multiple protrusions 31a of the same touch electrode block 31 are also arranged along the second direction D2. Therefore, the signal line 20 can overlap with the multiple protrusions 31a. Since the protrusions 31a of two adjacent touch electrode blocks 31 are arranged in an interlaced manner, the same signal line 20 can overlap with the protrusions 31a of two adjacent touch electrode blocks 31. Therefore, the same signal line 20 can be coupled with two adjacent touch electrode blocks 31, thereby reducing the coupling amount between the same signal line 20 and any one of the two touch electrode blocks 31, and improving the problem of uneven display.

[0056] In the display panel 1 of the present application, Figure 4A As shown, the protrusion 31 a corresponds to at least one sub-pixel 11 in the second direction D2 , and / or the protrusion 31 a corresponds to at least one sub-pixel 11 in the first direction D1 .

[0057] In some embodiments, the number of sub-pixels 11 corresponding to the first protrusion 311 a and the second protrusion 312 a can be set according to the frequency of the scanning signal.

[0058] In the display panel 1 of the present application, Figure 1A and Figure 5 As shown, the signal line 20 includes a scanning line 21, which transmits a clock signal; at the same moment, a rising edge 21a of the clock signal of a sub-pixel 11 corresponding to at least one protrusion 31a coincides with a falling edge 21b of the clock signal of another sub-pixel 11 corresponding to the touch electrode block 31, or a falling edge 21b of the clock signal of a sub-pixel 11 corresponding to at least one protrusion 31a coincides with a rising edge 21a of the clock signal of another sub-pixel 11 corresponding to the touch electrode block 31.

[0059] In this embodiment, if Figure 5 As shown, the scan line 21 transmits a clock signal, and the clock signal includes a rising edge 21a and a falling edge 21b. At the rising edge 21a of the clock signal, the touch electrode layer 30 is coupled with the scan line 21, and the voltage of the touch electrode layer 30 is affected by the coupling and deviates in the direction of the rising edge 21a, so that the voltage on the touch electrode layer 30 increases. At the falling edge 21b of the clock signal, the touch electrode layer 30 is coupled with the scan line 21, and the voltage of the touch electrode layer 30 is affected by the coupling and deviates in the direction of the falling edge 21b, so that the voltage on the touch electrode layer 30 decreases.

[0060] For ease of description, two adjacent touch electrode blocks 31 along the first direction D1 are respectively referred to as a first electrode block 311 and a second electrode block 312. The first electrode block 311 inputs a first common voltage VCOM1, and the second electrode block 312 inputs a second common voltage VCOM2. The magnitudes of VCOM1 and VCOM2 are equal. The first electrode block 311 may correspond to the G1 to GN row scan lines 21, and the second electrode block 312 may correspond to the GN+1 to G2N row scan lines 21. Where G1 to GN refer to the 1st scan line 21 to the Nth scan line 21 along the first direction D1, and GN+1 to G2N refer to the (N + 1)th scan line 21 to the 2Nth scan line 21 along the first direction D1, that is, the first electrode block 311 and the second electrode block 312 may respectively correspond to N scan lines 21. It should be understood that the value of N can be set as needed, and the present application does not limit this. In order to make the coupling degrees of the first electrode block 311 and the second electrode block 312 consistent, the number of scan lines 21 corresponding to the first electrode block 311 and the second electrode block 312 may be the same.

[0061] In one embodiment, as Figure 5 shown by the vertical dotted line in

[0062] the falling edge 21b of the clock signal of the G1st row and the rising edge 21a of the clock signal of the G5th row are at the same moment, that is, the coupling amount between the 1st scan line 21 and the touch electrode block 31 and the coupling amount between the 5th scan line 21 and the touch electrode block 31 cancel each other out. Similarly, the falling edge 21b of the 2nd scan line 21 and the rising edge 21a of the clock signal of the G6th row are at the same moment, and the coupling amounts cancel each other out. After cancellation, for the first electrode block 311, the coupling amounts of multiple clock signals in the middle region cancel each other out, while the rising edges 21a of the scan signals of G1 to G4 and the falling edges 21b of the scan signals of GN-3 to GN cannot be cancelled. Similarly, the rising edges 21a of the scan signals of GN+1 to GN+4 cannot be cancelled.

[0063] Since the common voltage of the first electrode block 311 is coupled as VCOM1', and the common voltage of the second electrode block 312 is coupled as VCOM2', VCOM1' and VCOM2' are not equal, resulting in different voltage differences between VCOM1' and the pixel electrode, and different voltage differences between VCOM2' and the pixel electrode, which affects the deflection of the liquid crystal molecules in the liquid crystal layer, causing the brightness of the sub-pixels 11 corresponding to the scanning lines 21 from GN-3 to GN+4 to deviate from the normal value, i.e., the display is uneven, which is visually manifested as horizontal stripes.

[0064] In this embodiment, since the first electrode block 311 includes a plurality of protrusions 31a, when the protrusion 31a corresponds to a sub-pixel 11 on the same column, the protrusion 31a of the first electrode block 311 can correspond to the GN+1th scan line 21, so that the falling edge 21b of GN-3 and the rising edge 21a of GN+1 can cancel each other. When the protrusion 31a corresponds to two sub-pixels 11 on the same column, the falling edge 21b of GN-3 and the rising edge 21a of GN+1 can cancel each other, and the falling edge 21b of GN-2 and the rising edge 21a of GN+2 can cancel each other, so as to at least reduce the coupling amount between the first electrode block 311 and the GN-3th scan line 21, reduce the number of troughs caused by the coupling between the first electrode block 311 and the scan line 21, and improve the phenomenon of uneven display.

[0065] It should be noted that the number of sub-pixels 11 in the same column corresponding to the protrusions 31 a of the first electrode block 311 can be adjusted according to the number of rising edges 21 a of the scanning signal, and the present application does not impose any limitation on this.

[0066] Similarly, the protrusion 31 a of the second electrode block 312 can reduce the number of peaks caused by the coupling between the second electrode block 312 and the scan line 21 , thereby improving the phenomenon of uneven display.

[0067] In the display panel 1 of the present application, Figure 1B and Figure 4B As shown, the signal line 20 includes a data line 22, and the data line 22 transmits a voltage signal; any two adjacent sub-pixels 11 in the second direction D2 have the same color, and the two adjacent sub-pixels 11 are arranged corresponding to one protrusion 31a.

[0068] In this embodiment, the signal line 20 may be a data line 22, and the data line 22 transmits a voltage signal. Specifically, the data line 22 may be connected to the pixel electrode of the sub-pixel 11, so as to input a pixel voltage to the sub-pixel 11. The liquid crystal molecules of the liquid crystal layer corresponding to the sub-pixel 11 are deflected under the electric field of the common voltage and the pixel voltage, thereby realizing the brightness control of the display panel 1.

[0069] In this embodiment, two adjacent sub-pixels 11 in the second direction D2 have the same color. For example, the sub-pixels 11 in the same pixel group 10 may all be red sub-pixels, or all be green sub-pixels, or all be blue sub-pixels.

[0070] In this embodiment, please refer to Figure 4B , two sub-pixels 11 adjacent along the first direction D1 are arranged corresponding to one protrusion 31a. Specifically, the touch electrode block 31 may include a plurality of protrusions 31a arranged along the second direction D2, and a groove is arranged between two adjacent protrusions 31a. The protrusions 31a of two touch electrode blocks 31 adjacent along the first direction D1 are arranged in an alternating manner, that is, the protrusions 31a and the grooves of two touch electrode blocks 31 adjacent along the first direction D1 are mutually embedded.

[0071] In this embodiment, since the colors of the multiple sub-pixels 11 in the second direction D2 are the same, the two sub-pixels 11 can be one cycle. It can be understood that the number of sub-pixels 11 corresponding to each protrusion 31a can also be multiple, and this application does not limit this. The number of protrusions 31a of two adjacent touch electrode blocks 31 along the first direction D1 can be the same, so that the coupling amount of the two to the data line 22 is consistent, that is, the coupling amount of each touch electrode block 31 with the protrusion 31a is halved, so that the coupling degree of the two adjacent touch electrode blocks 31 is constant, further improving the horizontal stripe phenomenon.

[0072] In the display panel 1 of the present application, Figure 2 As shown, the display panel 1 includes touch wirings 23 , and one touch wiring 23 is electrically connected to one touch electrode block 31 .

[0073] In this embodiment, the touch electrode block 31 and the touch wiring 23 are arranged in different layers, and one touch electrode block 31 can be connected to one touch wiring 23 through a via 51. The touch wiring 23 can extend along the first direction D1. The touch wiring 23 is used to transmit touch signals.

[0074] The display panel 1 may further include a touch chip 50. One end of the touch trace 23 may be electrically connected to the touch electrode block 31, and the other end may be electrically connected to the touch chip 50. The touch chip 50 may be disposed in the non-display area NA.

[0075] Optionally, the touch control chip 50 and the driver chip 13 are disposed on the same side of the display area AA. The touch control chip 50 and the driver chip 13 may also be integrated.

[0076] When a touch medium such as a finger touches the display panel 1 , the touch electrode block 31 in the corresponding area receives a touch signal and transmits the touch signal to the touch chip 50 through the touch wiring 23 , thereby locating the finger and realizing the touch function.

[0077] Optionally, the display panel 1 may be a self-capacitive touch panel.

[0078] Due to the coupling between the touch electrode block 31 and the touch wiring 23, vertical lines may be defective. Correspondingly, protrusions 31a may be provided on multiple edges of the touch electrode block 31, that is, protrusions 31a are provided on the periphery of the touch electrode block 31. The touch wiring 23 overlaps with the protrusions 31a of two touch electrode blocks 31 adjacent to each other along the second direction D2. The setting of the protrusions 31a of the touch electrode block 31 can refer to the setting in the above embodiment, and will not be repeated here.

[0079] In the display panel 1 of the present application, Figure 4A As shown, the colors of three adjacent sub-pixels 11 in the second direction D2 are all different, and every three adjacent sub-pixels 11 are arranged corresponding to one protrusion 31 a.

[0080] In this embodiment, one protrusion 31a may include a first protrusion 311a and a second protrusion 312a, the first protrusion 311a and the second protrusion 312a respectively correspond to one of two adjacent columns of sub-pixels 11, the first protrusion 311a may correspond to two sub-pixels 11, the second protrusion 312a may correspond to one sub-pixel 11, and the first protrusion 311a may be adjacent to a groove, which may correspond to two sub-pixels 11. Through the above arrangement, every three sub-pixels 11 along the second direction D2 may be a cycle, so that the sub-pixels 11 corresponding to two touch electrode blocks 31 adjacent to each other along the first direction D1 are evenly distributed, so that the coupling amount between two adjacent touch electrodes and the corresponding signal line 20 is reduced to the same extent, thereby further improving the display unevenness.

[0081] In the display panel 1 of the present application, any two adjacent touch electrode blocks 31 are insulated from each other, and any two adjacent touch electrode blocks 31 are connected to a common voltage signal.

[0082] In this embodiment, two adjacent touch electrode blocks 31 are insulated, and in the touch control stage, each touch electrode block 31 corresponds to an independent common voltage signal, which may be VCOM.

[0083] In the display panel 1 of the present application, Figure 2 As shown, the display panel 1 includes at least one first auxiliary line 41 and at least one second auxiliary line 42 . The first auxiliary line 41 and the second auxiliary line 42 extend in the same direction as the signal line 20 . The first auxiliary line 41 and the second auxiliary line 42 are arranged on opposite sides of all the signal lines 20 .

[0084] In this embodiment, the first auxiliary line 41 and the second auxiliary line 42 may extend in the same direction as the signal line 20, that is, the first auxiliary line 41 and the second auxiliary line 42 may extend along the second direction D2. The first auxiliary line 41 is disposed on the side of the first signal line 20 away from the center of the display area AA, and the second auxiliary line 42 is disposed on the side of the last signal line 20 away from the center of the display area AA. The first auxiliary line 41 and the second auxiliary line 42 may be disposed outside the display area AA.

[0085] The first auxiliary line 41 and the second auxiliary line can input a driving signal, but the driving signal may not be connected to any sub-pixel 11 of the pixel group 10. Through the above arrangement, the touch electrode block 31 in the edge area of ​​the display panel 1 and the touch electrode block 31 in the center area of ​​the display panel 1 can be affected by the driving signal in the same manner, thereby optimizing the sensitivity of the touch electrode block 31 in the edge area.

[0086] like Figure 6 As shown, the present application also provides a display terminal 2, and the display terminal 2 includes the above-mentioned display panel 1.

[0087] In this embodiment, the display terminal 2 includes a display panel 1 and a terminal body 3, and the display panel 1 and the terminal body 3 are combined into one body.

[0088] In this embodiment, the display terminal 2 can be any product or component with a display function, such as a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, etc.
