Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of display, and in particular, to an array substrate, a display panel, a display device and a driving method. BACKGROUND

[0002] Extended Reality (XR) refers to combining reality and virtuality through a computer to create a virtual environment that can be interacted with a human. It is also a general term for AR (Augmented Reality), VR (Virtual Reality) and MR (Mixed Reality) technologies. By integrating the visual interaction technologies of the three, it brings the "immersion" of seamless conversion between the virtual world and the real world to the experimenter.

[0003] In order to obtain a better visual experience, it is required that the extended reality display device has a high resolution and a high refresh rate. However, it is relatively difficult to achieve both indicators within a limited charging time. Therefore, how to have a high refresh rate under the premise of a high resolution of the extended reality display device in the case of a short charging time is a problem to be solved at present. SUMMARY

[0004] In order to solve the above technical problems or at least partially solve the above technical problems, the present disclosure provides an array substrate, a display panel, a display device and a driving method.

[0005] In a first aspect, the present disclosure provides an array substrate, which comprises a left-eye display area and a right-eye display area.

[0006] The left-eye display area comprises N first sub-display areas arranged along a column direction; the right-eye display area comprises N second sub-display areas arranged along the column direction; N is a positive integer greater than or equal to 2.

[0007] The data writing time of one frame comprises a left-eye image refresh period and a right-eye image refresh period, the left-eye image refresh period and the right-eye image refresh period do not overlap in time; in the left-eye image refresh period, the image refresh frequency of each first sub-display area is the same; in the right-eye image refresh period, the image refresh frequency of each second sub-display area is the same.

[0008] In a second aspect, the present disclosure further provides a display panel, which comprises the array substrate as described above.

[0009] In a third aspect, the present disclosure further provides a display device, which comprises the display panel as described above.

[0010] In a fourth aspect, the present disclosure provides a driving method for driving the display panel as described above; a data writing time of one frame includes a left-eye image refreshing period and a right-eye image refreshing period, and the left-eye image refreshing period and the right-eye image refreshing period do not overlap in time;

[0011] The driving method includes:

[0012] In the left-eye image refreshing period, images displayed by the first sub-display areas are refreshed synchronously so that the image refreshing frequencies of the first sub-display areas are the same;

[0013] In the right-eye image refreshing period, images displayed by the second sub-display areas are refreshed synchronously so that the image refreshing frequencies of the second sub-display areas are the same.

[0014] The technical solution provided by the embodiments of the present disclosure has the following advantages compared with the prior art:

[0015] In the technical solution provided by the embodiments of the present disclosure, the left-eye display area includes N first sub-display areas arranged along the column direction, the right-eye display area includes N second sub-display areas arranged along the column direction, the data writing time of one frame includes a left-eye image refreshing period and a right-eye image refreshing period, in the left-eye image refreshing period, the image refreshing frequencies of the first sub-display areas are the same, and in the right-eye image refreshing period, the image refreshing frequencies of the second sub-display areas are the same. The essence is to divide the left-eye display area and the right-eye display area into multiple sub-areas respectively, so as to reduce the number of rows that need to be refreshed in each sub-area. Since the multiple sub-areas in the left-eye display area are refreshed synchronously and the multiple sub-areas in the right-eye display area are refreshed synchronously, the overall refreshing time of the left-eye display area and the right-eye display area can be reduced, thereby achieving the purpose of improving the refreshing frequency of the extended reality display device including the array substrate while ensuring that the extended reality display device has a high resolution.

[0029] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the schemes of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the description are only some of the embodiments of the present disclosure, not all the embodiments.

[0031] Figure 1 A structure diagram of an array substrate provided by an embodiment of the present disclosure is shown in FIG. 1. Figure 2 A structure diagram of an array substrate provided by an embodiment of the present disclosure is shown in FIG. 1. Figure 1A schematic diagram of a driving timing of the middle array substrate. Referring to Figure 1 The array substrate includes a left-eye display area A and a right-eye display area B. The left-eye display area A includes N first sub-display areas arranged along a column direction; the right-eye display area B includes N second sub-display areas arranged along the column direction; N is a positive integer greater than or equal to 2. Figure 1 In an example, N = 2, the left-eye display area A includes two first sub-display areas, namely, a first sub-display area A1 and a first sub-display area A2. The right-eye display area B includes two second sub-display areas, namely, a second sub-display area B1 and a second sub-display area B2.

[0032] Referring to Figure 2 The data writing time t1 of one frame includes a left-eye image refreshing period t11 and a right-eye image refreshing period t12, the left-eye image refreshing period t11 and the right-eye image refreshing period t12 do not overlap in time; in the left-eye image refreshing period t11, the image refreshing frequencies of the first sub-display areas A1 are the same; in the right-eye image refreshing period t12, the image refreshing frequencies of the second sub-display areas B1 are the same.

[0033] Continuing to refer to Figure 2 The purpose of dividing the data writing time t1 into the left-eye image refreshing period t11 and the right-eye image refreshing period t12 is to ensure that the left-eye image is seen by the left eye and the right-eye image is seen by the right eye, so as to make the human eye automatically generate a stereoscopic sense corresponding to the picture and realize a 3D display effect.

[0034] Refreshing a region should be understood as turning on the control switch of the pixel unit in the region row by row, so that the data signal is written into the pixel unit. The refreshing time length of a region is mainly determined by the number of rows of pixel units in the region.

[0035] If the left-eye display area is not divided into multiple first sub-display areas, it means that the left-eye display area is refreshed as a region.

[0036] In the present application, by arranging the left-eye display area to include N first sub-display areas arranged along the column direction, the image refreshing frequencies of the first sub-display areas are the same in the left-eye image refreshing period, which is essentially dividing the left-eye display area into multiple sub-regions and synchronously refreshing the multiple sub-regions. In this way, the refreshing time length of the left-eye display area will be equal to the refreshing time length of the first sub-display area with the most rows.

[0037] In the case of the same number of rows in the left-eye display area, compared with the case of refreshing the left-eye display area as a region, by dividing the left-eye display area into N sub-regions, the number of rows that need to be scanned for each sub-region can be reduced, and thus the overall refreshing time length of the left-eye display area can be reduced.

[0038] Further, in the case that the left-eye display area is divided into N first sub-display areas, and the number of rows of pixel units in any two first sub-display areas is the same, the refresh time of the left-eye display area can be shortened to 1 / N of the refresh time required before the division.

[0039] Similarly, if the right-eye display area is not divided into multiple second sub-display areas, it means that the right-eye display area is refreshed as a whole.

[0040] In the present application, by setting the right-eye display area to include N second sub-display areas arranged along the column direction, the image refresh frequency of each second sub-display area is the same within the right-eye image refresh period. In essence, the right-eye display area is divided into multiple sub-areas to reduce the number of rows that need to be refreshed in each sub-area. Since multiple sub-areas are refreshed synchronously, the overall refresh time of the right-eye display area can be reduced.

[0041] Therefore, the above technical solution can shorten the refresh time of a single frame of left-eye and right-eye images by setting the left-eye display area to include N first sub-display areas arranged along the column direction, and the right-eye display area to include N second sub-display areas arranged along the column direction, the image refresh frequency of each first sub-display area being the same within the left-eye image refresh period, and the image refresh frequency of each second sub-display area being the same within the right-eye image refresh period. This can improve the refresh frequency of the extended reality display device including the array substrate while ensuring that the extended reality display device has a high resolution.

[0042] On the basis of the above technical solution, optionally, each first sub-display area in the left-eye display area includes P rows of pixel units, and the left-eye image refresh period includes P first sub-periods; in any first sub-period, there is a row of pixel units in a data write state in each first sub-display area; for the same first sub-display area, in different first sub-periods, the pixel units in the write state belong to different rows; each second sub-display area in the right-eye display area includes P rows of pixel units, and the right-eye image refresh period includes P second sub-periods; in any second sub-period, there is a row of pixel units in a data write state in each second sub-display area; for the same second sub-display area, in different second sub-periods, the pixel units in the write state belong to different rows; P is a positive integer.

[0043] Figure 3 Another structure diagram of a left-eye part in an array substrate provided by the embodiments of the present disclosure is provided. Referring to FIG. 4, the left-eye display area 401 includes N first sub-display areas 4011, 4012, 4013, 4014, and 4015 arranged along the column direction. Figure 3, the array substrate, the left eye display area includes 2 first sub display areas, respectively first sub display area A1 and first sub display area A2, first sub display area A1 and first sub display area A2 include P rows of pixel units, left eye image refresh period includes P first sub period; P first sub period does not coincide with each other. Assuming that the length of each first sub period is △t, when a left eye image of a frame is refreshed, the initial time is T0, then in the period of T0 to T0+△t, the first row of pixel units X1 in first sub display area A1 and the first row of pixel units Y1 in first sub display area A2 are in data writing state. In the period of T0+△t to T0+2△t, the second row of pixel units X2 in first sub display area A1 and the second row of pixel units Y2 in first sub display area A2 are in data writing state. In the period of T0+2△t to T0+3△t, the third row of pixel units X3 in first sub display area A1 and the third row of pixel units Y3 in first sub display area A2 are in data writing state. In the period of T0+(P-1)△t to T0+P△t, the Pth row of pixel units XP in first sub display area A1 and the Pth row of pixel units YP in first sub display area A2 are in data writing state. In this way, the image refresh frequency of each first sub display area can be the same in the left eye image refresh period.

[0044] The refresh mode of the right eye side pixel unit is similar to that of the left eye side pixel unit, which will not be described here.

[0045] On the basis of the above technical solutions, optionally, each first sub display area and each second sub display area includes a plurality of scanning lines and a plurality of data lines; the plurality of scanning lines and the plurality of data lines cross each other to define a plurality of pixel regions, the pixel unit is located in the pixel region, one scanning line is arranged between two adjacent rows of pixel units, and one data line is arranged between two adjacent columns of pixel units; the array substrate includes N first scanning drive circuits and N second scanning drive circuits; the first scanning drive circuit corresponds to the first sub display area one by one, each first scanning drive circuit and the scanning line in the first sub display area corresponding to it are electrically connected; each first scanning drive circuit is used for inputting a scanning drive signal to the scanning line connected thereto in each first sub period; the second scanning drive circuit corresponds to the second sub display area one by one, each second scanning drive circuit and the scanning line in the second sub display area corresponding to it are electrically connected; each second scanning drive circuit is used for inputting a scanning drive signal to the scanning line connected thereto in each second sub period.

[0046] For example, continuing to refer to Figure 3, the first sub-display area A1 and the first sub-display area A2 each include a plurality of scanning lines 1 and a plurality of data lines 2; the plurality of scanning lines 1 and the plurality of data lines 2 cross each other to define a plurality of pixel areas 3, a pixel unit 4 is located in the pixel area 3, a scanning line 1 is arranged between two adjacent rows of pixel units 4, and a data line 2 is arranged between two adjacent columns of pixel units 4; the array substrate includes two first scan driving circuits, which are a first scan driving circuit VSR1 and a first scan driving circuit VSR2.

[0047] The first scan driving circuit VSR1 corresponds to the first sub-display area A1, the first scan driving circuit VSR1 is electrically connected with all the scanning lines 1 in the first sub-display area A1, and is configured to input a scan driving signal to a scanning line 1 connected therewith in each first sub-time period, such as inputting a scan signal to the scanning line 1 electrically connected with the first row of pixel units X1 in the T0 to T0+△t time period; inputting a scan signal to the scanning line 1 electrically connected with the second row of pixel units X2 in the T0+△t to T0+2△t time period; inputting a scan signal to the scanning line 1 electrically connected with the third row of pixel units X3 in the T0+2△t to T0+3△t time period; and so on.

[0048] The first scan driving circuit VSR2 corresponds to the first sub-display area A2, the first scan driving circuit VSR2 is electrically connected with all the scanning lines 1 in the first sub-display area A2, and is configured to input a scan driving signal to a scanning line 1 connected therewith in each first sub-time period, such as inputting a scan signal to the scanning line 1 electrically connected with the first row of pixel units Y1 in the T0 to T0+△t time period; inputting a scan signal to the scanning line 1 electrically connected with the second row of pixel units Y2 in the T0+△t to T0+2△t time period; inputting a scan signal to the scanning line 1 electrically connected with the third row of pixel units Y3 in the T0+2△t to T0+3△t time period; and so on.

[0049] The connection mode of the right-eye-side second scan driving circuit and the scanning line is similar to the connection mode of the left-eye-side first scan driving circuit and the scanning line, which will not be described here.

[0050] By using the above method, the image of each first sub-display area can be refreshed synchronously in the left-eye image refreshing time period, and the image of each second sub-display area can be refreshed synchronously in the right-eye image refreshing time period without changing the circuit structure of the existing scan driving circuit, so that the refresh frequency of the extended reality display device including the array substrate is improved.

[0051] Based on the above technical solutions, optionally, a driver chip can be used to provide data signals for the data line.

[0052] There are various methods for using a driver chip to provide data signals to the data line, and this application does not limit this approach. Two exemplary methods are given below.

[0053] Setup Method 1:

[0054] The array substrate also includes N first driver chips; the Qth first driver chip is electrically connected to each data line of the Qth first sub-display area in the left eye display area and each data line of the Qth second sub-display area in the right eye display area, where Q is a positive integer less than or equal to N.

[0055] Figure 4 This is a schematic diagram of another array substrate provided in an embodiment of this disclosure. For example, see... Figure 4 The array substrate includes two first driver chips, namely first driver chip IC11 and first driver chip IC12. First driver chip IC11 is electrically connected to each data line 2 of the first sub-display area A1 in the left eye display area A, and to each data line 2 of the second sub-display area B1 in the right eye display area B. First driver chip IC12 is electrically connected to each data line 2 of the first sub-display area A2 in the left eye display area A, and to each data line 2 of the second sub-display area B2 in the right eye display area B.

[0056] In the current extended reality display field, the left-eye display area is not further divided into multiple first sub-display areas, nor is the right-eye display area further divided into multiple second sub-display areas. Typically, a driver chip is electrically connected to the data lines in only one display area. For example, if the array substrate includes two driver chips, one connected to the data lines in the left-eye display area and the other connected to the data lines in the right-eye display area, then due to the large number of connection pins on the driver chip, in existing solutions, only a few pins are electrically connected to the data lines in the array substrate, while the remaining pins are idle and not connected to any signal lines, thus the driver chip is not being fully utilized.

[0057] The above-mentioned technical method, by electrically connecting the Qth first driver chip to each data line of the Qth first sub-display area in the left eye display area and each data line of the Qth second sub-display area in the right eye display area, can achieve the goal of ensuring synchronous refresh of the images of each first sub-display area during the left eye image refresh period and synchronous refresh of the images of each second sub-display area during the right eye image refresh period, without increasing the number of driver chips and increasing the manufacturing cost of the array substrate.

[0058] Optionally, the first driving chip is located at the non-light-emitting side of the array substrate. In this way, the size of the array substrate can be reduced, so as to adapt to the development trend of narrow frame of the extended reality display device.

[0059] In some embodiments, optionally, the array substrate further comprises a non-display area, the non-display area surrounds the left-eye display area and / or the right-eye display area; and the first driving chip is located in the non-display area of the array substrate.

[0060] In other embodiments, optionally, the first driving chip and the data lines can be electrically connected by means of COF (Chip On Flex, or, Chip On Film, Chip On Film).

[0061] Exemplarily, referring to Figure 4 , the array substrate further comprises a non-display area, and two first binding areas and two second binding areas are arranged in the non-display area; the two first binding areas are a first binding area C1 and a first binding area C2 respectively; and the two second binding areas are a second binding area D1 and a second binding area D2 respectively.

[0062] The distance between the first binding area C1 and the first sub-display area A1 is less than a preset distance (i.e., the first binding area C1 is located near the first sub-display area A1), and the data line 2 in the first sub-display area A1 extends to the first binding area C1. The distance between the second binding area D1 and the second sub-display area B1 is less than a preset distance (i.e., the second binding area D1 is located near the second sub-display area B1), and the data line 2 in the second sub-display area B1 extends to the first binding area C1.

[0063] The distance between the first binding area C2 and the first sub-display area A2 is less than a preset distance (i.e., the first binding area C2 is located near the first sub-display area A2), and the data line 2 in the first sub-display area A2 extends to the first binding area C2. The distance between the second binding area D2 and the second sub-display area B2 is less than a preset distance (i.e., the second binding area D2 is located near the second sub-display area B2), and the data line 2 in the second sub-display area B2 extends to the first binding area C2.

[0064] The array substrate further comprises two third flexible circuit boards, which are a third flexible circuit board F31 and a third flexible circuit board F32. Each third flexible circuit board comprises a seventh connection end, an eighth connection end and a ninth connection end.

[0065] The seventh connection terminal of the third flexible circuit board F31 is fixed in the first bonding area C1 and electrically connected to the data line 2 extending into the first bonding area C1. The eighth connection terminal of the third flexible circuit board F31 is fixed in the second bonding area D1 and electrically connected to the data line 2 extending into the second bonding area D1. The first driver chip IC1 is fixed on the third flexible circuit board F31 and electrically connected to the ninth connection terminal of the third flexible circuit board F31. This arrangement facilitates bending the third driver chip IC1 onto the non-light-emitting side of the array substrate.

[0066] The seventh connection terminal of the third flexible circuit board F32 is fixed in the first bonding area C2 and electrically connected to the data line 2 extending into the first bonding area C2. The eighth connection terminal of the third flexible circuit board F32 is fixed in the second bonding area D2 and electrically connected to the data line 2 extending into the second bonding area D2. The first driver chip IC2 is fixed on the third flexible circuit board F32 and electrically connected to the ninth connection terminal of the third flexible circuit board F32. This arrangement facilitates bending the third driver chip IC2 onto the non-light-emitting side of the array substrate.

[0067] Setup Method Two:

[0068] The array substrate also includes a second driver chip and a third driver chip; the second driver chip is electrically connected to each data line of each first sub-display area in the left eye display area; the third driver chip is electrically connected to each data line of each second sub-display area in the right eye display area.

[0069] Figure 5 A schematic diagram of the structure of the left eye portion of another array substrate provided in an embodiment of this disclosure. See also... Figure 5 In this array substrate, the left-eye display area A includes two first sub-display areas, namely first sub-display area A1 and first sub-display area A2. The right-eye display area B includes two second sub-display areas, namely second sub-display area B1 and second sub-display area B2. The array substrate also includes a second driver chip IC2 and a third driver chip IC3. The second driver chip IC2 is electrically connected to each data line 2 in the first sub-display areas A1 and A2. The third driver chip IC3 is electrically connected to each data line 2 in the second sub-display areas B1 and B2. This configuration allows for the electrical connection of idle connection pins in the prior art to the data lines 2 without increasing the number of driver chips. This ensures that the images of each first sub-display area are refreshed synchronously during the left-eye image refresh period and that the images of each second sub-display area are refreshed synchronously during the right-eye image refresh period; on the other hand, it does not increase the manufacturing cost of the array substrate.

[0070] On the basis of the above technical solution, optionally, N=2, the second driving chip and the third driving chip are located at the non-light-emitting side of the array substrate. This arrangement has the advantage of avoiding the second driving chip and the third driving chip occupying the display area and affecting the image display effect.

[0071] Based on this, further, the array substrate can be further configured to include a first region, a second region, a first flexible circuit board, and a second flexible circuit board; the first region includes a left-eye display area and a first non-display area surrounding the left-eye display area; the first flexible circuit board includes opposite first and second connecting ends and a third connecting end between the first and second connecting ends; the second driving chip is fixed on the first flexible circuit board and electrically connected to the third connecting end; the first flexible circuit board is in a bent state, and the first and second connecting ends are both fixed in the first region and located on opposite sides of the left-eye display area; the first connecting end is electrically connected to a data line in a first first sub-display area; the second connecting end is electrically connected to a data line in a second first sub-display area; the second region includes a right-eye display area and a second non-display area surrounding the right-eye display area; the second flexible circuit board includes opposite fourth and fifth connecting ends and a sixth connecting end between the fourth and fifth connecting ends; the third driving chip is fixed on the second flexible circuit board and electrically connected to the sixth connecting end; the second flexible circuit board is in a bent state, and the fourth and fifth connecting ends are both fixed in the second region and located on opposite sides of the right-eye display area; the fourth connecting end is electrically connected to a data line in a first second sub-display area; and the fifth connecting end is electrically connected to a data line in a second second sub-display area.

[0072] Figure 6 Another structural schematic diagram of a left-eye portion of an array substrate is provided for the embodiments of the present disclosure. Figure 7 To Figure 6 A structural schematic diagram of the array substrate in the embodiment after being flipped 180° along the left-right direction.

[0073] Figure 8 To flip Figure 6 A cross-sectional structural schematic diagram of G1-G2 in the embodiment. Illustratively, because Figures 6-8 Only the structure of the left-eye portion of the array substrate is shown, which only includes the first region, and the first region can be regarded as the left-eye region, in other words, the first region can be regarded as the union of the left-eye display area and the first non-display area surrounding the left-eye display area.

[0074] The first flexible circuit board F1 includes opposite first and second connecting ends F11 and F12 and a third connecting end F13 between the first and second connecting ends F11 and F12 (in the embodiment, the third connecting end F13 is located on the left side of the first connecting end F11 and the right side of the second connecting end F12). Figure 6The third connection end is shielded by the second driving chip IC2); the second driving chip IC2 is fixed on the first flexible circuit board F1 and is electrically connected with the third connection end F13; the first flexible circuit board F1 is in a bent state, the first connection end F11 and the second connection end F12 are both fixed in the first area and are located on the light-emitting side of the array substrate, and the first connection end F11 and the second connection end F12 are located on opposite sides of the left-eye display area A; the first connection end F11 is electrically connected with the data line 2 in the first sub-display area A1; and the second connection end F12 is electrically connected with the data line 2 in the first sub-display area A2. The third connection end F13 is fixed on the non-light-emitting side of the array substrate. In this way, the purpose of arranging the second driving chip IC2 on the non-light-emitting side of the array substrate can be achieved.

[0075] The arrangement mode of the right-eye side second area, the second flexible circuit board and the third driving chip is similar to the arrangement mode of the left-eye side first area, the first flexible circuit board and the second driving chip, and details are not described herein.

[0076] It should be noted that, in practice, the array substrate further includes a substrate, and the scan lines, the data lines and the pixel units are arranged on the substrate. In some embodiments, as shown in FIG. 1, the array substrate includes only one substrate M, and the left-eye display area A and the right-eye display area B are both located on the substrate. In other embodiments, as shown in FIG. 2, the array substrate includes two substrates, i.e., a first substrate M1 and a second substrate M2, the left-eye display area A is located on the first substrate M1, and the right-eye display area B is located on the second substrate M2. Figure 1 Figure 4

[0077] On the basis of the above technical solutions, optionally, the array substrate further includes a demultiplexer, and the demultiplexer is located between the driving chip and the data line.
