[0057] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0058] In various display application scenarios, in order to obtain better image quality or provide a more comfortable experience for users, it is required that the display device can actively adjust the display effect as the use scenario changes. Therefore, it is necessary to have an environmental monitoring function to obtain reference environmental parameters in order to perform targeted adjustment. In the related art, it is precisely through the light sensor that the automatic screen brightness adjustment function of the display device is realized. In addition to the external light sensor, there is also a method in the related art to prepare the light sensor using the original panel process line. By integrating the light sensor on the display panel, the overall cost of the display device is greatly reduced. However, in some solutions in the related art, the light sensor is disposed in the display area of the display panel, adjacent to the sub-pixels. These solutions will occupy the effective display space, have a certain impact on the display image quality, and will occupy the effective display time in the driving timing; in other solutions in the related art, the light sensor is disposed in the non-display area of the display panel, and an additional driving chip is used to realize the driving of the light sensor. This solution will increase the border width of the display panel and requires additional driving time in the driving timing.

[0059] Referring to Figures 1 to 3 As shown, according to the first aspect of the present application, the present application provides a display module 1, including a display panel 10 and a photosensitive module 200. Specifically, the display panel 10 further includes a pixel array, a plurality of scan lines, a plurality of scan lines, and one or more photosensitive modules 200.

[0060] Among them, the pixel array is composed of a plurality of sub-pixels 100, and includes m pixel rows and n pixel columns. Each pixel row is connected to a scan line, and there are n + 1 data lines. Each data line is connected to one or two pixel columns. In the row direction, the n sub-pixels of a sub-pixel row are sequentially connected to the first data line to the nth data line, and the n sub-pixels of another sub-pixel row are sequentially connected to the second data line to the (n + 1)th data line.

[0061] In some embodiments of the present application, the sub-pixel rows in which n sub-pixels are sequentially connected to the first data line to the nth data line are adjacent to the sub-pixel rows in which n sub-pixels are sequentially connected to the second data line to the (n + 1)th data line. In some specific embodiments, the sub-pixel rows in which n sub-pixels are sequentially connected to the first data line to the nth data line and the sub-pixel rows in which n sub-pixels are sequentially connected to the second data line to the (n + 1)th data line are alternately arranged to form the entire pixel array. It should be noted that this connection method between the sub-pixel rows and the data lines often appears in the display panel with a "zig-zag" arrangement. In the display panel with a zig-zag arrangement, although this alternate connection method can reduce the number of required connection lines, is beneficial to simplify the circuit design, and thus reduce the production cost, there will be unused data lines in the sub-pixel rows.

[0062] More specifically, in some embodiments of the present application, the arrangement of the sub-pixels in the display panel may be such that the n sub-pixels in the odd sub-pixel rows are sequentially connected to the first data line to the nth data line, and the n sub-pixels in the even sub-pixel rows are sequentially connected to the second data line to the (n + 1)th data line; or, the arrangement of the sub-pixels in the display panel may also be such that the n sub-pixels in the odd sub-pixel rows are sequentially connected to the second data line to the (n + 1)th data line, and the n sub-pixels in the even sub-pixel rows are sequentially connected to the first data line to the nth data line. It will be understood that according to different display panel design requirements, the sub-pixels may also adopt other arrangement methods, not limited to the foregoing two, and the present application will not elaborate herein.

[0063] On this basis, in the display panel 10 of the present application, each pixel is composed of three sub-pixels 100, namely a red sub-pixel 100, a green sub-pixel 100, and a blue sub-pixel 100. Among them, each sub-pixel 100 in each row is directly connected to the data line without passing through a multiplexer (MUX) in the plane. The odd-row sub-pixels 100 and the even-row sub-pixels 100 are respectively connected to adjacent data lines. For example, the first sub-pixels 100 in odd rows such as the first row, the third row, and the fifth row in the display area 10a can all be connected to the first data line. Correspondingly, the first sub-pixels 100 in even rows such as the second row, the fourth row, and the sixth row are all connected to the second data line, and the photosensitive module 200 and the sub-pixels 100 connected to the same data line are located in different pixel rows.

[0064] It should be noted that in the embodiments of the present application, the row direction is the x-axis direction shown in the figure, and the column direction is the y-axis direction shown in the figure. It can be understood that in the embodiments of the present application, the x-axis and y-axis are not limited to the two axes of the rectangular coordinate system and can be interpreted in a broader sense. For example, the x-axis and y-axis can be perpendicular to each other, or according to different design requirements of the display panel, such as in a curved screen, the x-axis and y-axis can represent different directions that are not perpendicular to each other.

[0065] Specifically, referring to Figure 1 As shown, in some embodiments of the present application, the photosensitive module 200 includes: a first type of photosensitive module 200a, and the first type of photosensitive module 200a is disposed on at least one side of the pixel array in the row direction. Each photosensitive module 200 is respectively connected to one of the scan lines and one of the data lines. Correspondingly, in Figure 1 the first type of photosensitive module 200a is the photosensitive module 200 formed on the left side and / or the right side of the pixel array.

[0066] More specifically, in some embodiments of the present application, in a sub-pixel row where n sub-pixels are sequentially connected to the first data line to the nth data line, the first type of photosensitive module 200a is connected to the (n + 1)th data line; and / or, in a sub-pixel row where n sub-pixels are sequentially connected to the second data line to the (n + 1)th data line, the first type of photosensitive module 200a is connected to the first data line. In some examples, the first type of photosensitive module 200a can be connected to the (n + 1)th data line of odd sub-pixel rows in the row direction; and / or, the first type of photosensitive module 200a is also connected to the first data line of even sub-pixel rows in the row direction.

[0067] It should be noted that in a display panel with a zig-zag arrangement, the scan signal is alternately transmitted from left to right or from right to left, which results in blank driving times for the aforementioned first data line and the (n + 1)th data line in some pixel rows. In this embodiment, the first type of photosensitive module 200a is driven by the signals transmitted during these blank driving times, making full use of the working driving time of the display panel, which is beneficial to improving the working efficiency of the display panel. In addition, the photosensitive module 200 is mainly arranged on the left and right sides of the display panel 10, and only two data lines are used to drive the corresponding photosensitive module 200, which can reduce the occupation of the border area 10b of the display panel 10 by the photosensitive module 200, and is beneficial to reducing the size of the border area 10b of the display panel 10.

[0068] Referring to Figure 2As shown, in some embodiments of the present application, the photosensitive module 200 may further include a second type of photosensitive module 200b, and the second type of photosensitive module 200b is disposed on at least one side of the pixel array in the column direction; the second type of photosensitive module 200b is connected to the first data line in the row direction; and / or, the second type of photosensitive module 200b is connected to the (n + 1)-th data line in the row direction. Different from the first type of photosensitive module 200a, the second type of photosensitive module 200b is disposed on the upper side and / or the lower side of the illustrated pixel array. In this embodiment, according to the size of the photosensitive module 200, etc., multiple second type of photosensitive modules 200b may be provided. By extending the length of the data line, multiple photosensitive modules 200 may also be provided to surround both sides and the upper side of the display area 10a. At the same time, some photosensitive modules 200 may also be provided below the display area 10a, and only two data lines are required to drive these photosensitive modules 200. That is, it is not necessary for each data line to have pixel driving ability and photosensitive driving ability. Multiple second type of photosensitive modules 200b can be driven by only two data lines corresponding to the photosensitive modules 200, and it is also possible to reduce the occupation of the border area 10b of the display panel 10 by the photosensitive module 200, which is beneficial to reducing the size of the border area 10b of the display panel 10.

[0069] Referring to Figure 3 As shown, in some embodiments of the present application, the photosensitive module 200 may further include a third type of photosensitive module 200c, and the third type of photosensitive module 200c is disposed on at least one side of the pixel array in the column direction, and the third type of photosensitive module is connected to at least some of the data lines from the second to the n-th data lines in the row direction. Similar to the second type of photosensitive module 200b, the third type of photosensitive module 200c is also disposed on the upper side and / or the lower side of the pixel array. The difference is that the third type of photosensitive module 200c may be connected to each data line, or is connected to multiple data lines at intervals. The distribution position of the third type of photosensitive module 200c may be designed according to actual needs, and the present application does not limit this here.

[0070] In this embodiment, since it is necessary to drive the third type of photosensitive module 200c, each data line connected to the third type of photosensitive module 200c needs to have pixel driving ability and photosensitive driving ability.

[0071] Combined with the above embodiments, the first photosensitive module 200a and the second photosensitive module 200b, or the combination of the first photosensitive module 200a, the second photosensitive module 200b and the third photosensitive module 200c, can all form a circle of photosensitive modules 200 around the display area 10a. Each photosensitive module 200 can obtain the ambient light parameters of the corresponding area. Finally, the ambient light parameters of the entire display area 10a of the display panel 10 can be obtained through the circle of photosensitive modules 200. By analyzing this parameter and combining other technologies such as real-time backlight adjustment, the effect of the display panel 10 can be adjusted in real time.

[0072] It should be noted that the above first type of photosensitive module 200a, second type of photosensitive module 200b and third type of photosensitive module 200c are only distinguished in terms of the position of the photosensitive module 200. In the actual implementation process, the photosensitive module 200 can adopt the same structure or different structures, and the present application does not limit this here.

[0073] In the above embodiment, the display panel further includes a display area 10a and a border area 10b provided outside the display area 10a. The photosensitive module 200 is disposed in the border area 10b to avoid occupying the display area of the display panel.

[0074] Specifically, referring to Figure 4 As shown, the photosensitive module 200 includes: a photosensitive unit 210 and a control unit 220. Among them, the photosensitive unit 210 is used to detect the ambient light parameters of the area where the photosensitive unit 210 is located, and the control unit 220 is used to control the startup and shutdown of the photosensitive unit 210.

[0075] More specifically, in some embodiments of the present application, the control unit 220 includes: a first pole connected to the data line; a second pole connected to the photosensitive unit 210; and a control pole connected to the scan line to control the current conduction between the first pole and the second pole. That is, the control unit 220 can adopt a transistor. Here, it should be noted that the transistor used in the embodiments of the present application can be a thin film transistor or a field effect transistor or other devices with the same characteristics. Since the source and drain of the adopted transistor are symmetrical, there is no difference between its source and drain. In the embodiments of the present application, to distinguish the source and drain of the transistor, one pole is called the first pole and the other pole is called the second pole. In addition, the gate of the transistor is called the control pole. In addition, according to the characteristics of the transistor, the transistor can be divided into N-type and P-type. In the following embodiments, the N-type transistor is used for illustration. When the N-type transistor is used, the first pole is the source of the N-type transistor, the second pole is the drain of the N-type transistor, and when the gate inputs a high level, the source-drain is turned on, and the P-type is the opposite. It can be imagined that implementing with a P-type transistor is easily conceivable by those skilled in the art without creative labor, and therefore it is also within the protection scope of the embodiments of the present application.

[0076] More specifically, in some embodiments of the present application, the photosensitive unit 210 includes a photosensitive diode and a capacitor. Among them, the input end of the photosensitive diode is connected to a common voltage, the output end of the photosensitive diode is connected to the second pole, one plate of the capacitor is connected to the input end of the photosensitive diode, and the other plate is connected to the output end of the photosensitive diode. The photosensitive diode can convert an optical signal into an electrical signal. When light irradiates the photosensitive diode, the energy of photons will excite electron-hole pairs in the semiconductor, thereby generating a current. The output current of the photosensitive diode is proportional to the light intensity. The capacitor is used to store charges to collect and store the current generated by the photosensitive diode. By controlling the charging and discharging process of the capacitor, the integration and measurement of the optical signal can be achieved.

[0077] Referring to Figure 5 As shown, it is a driving timing diagram of a display panel without a photosensitive module in the related art. Among them, S1, S2... Sn in the figure represent the data lines output by the driver IC, and Gate 1, Gate 2... Gate n represent each row of scan control lines. As shown in the figure, each row of scan control lines is opened in sequence. This figure shows the data types on the S1 and S2 data lines when each row of gates is opened. For example, when Gate 1 is opened, the S1 line drives the data R11, and the S2 line drives the data G11. When Gate 2 is opened, the S1 line does not output, and the S2 line drives the data R21, and so on.

[0078] Correspondingly, referring to Figure 6 As shown, it is a driving timing diagram of a display panel 10 of the present application. In some embodiments of the present application, photosensitive modules are provided on both sides of the display panel. The photosensitive modules are only connected to the first data line S1 and the last data line Sn. In this embodiment, compared with the display panel in the related art, there is no need to increase the number of scan control signals gate. When Gate 1 is opened, the S1 line drives the data R11, and the S2 line drives the data G11. When Gate 2 is opened, the S1 line drives ALS_11, and the S2 line drives the data R21, and so on. Similarly, on the right side of the panel, when each row of gates is opened, the Sn line also alternately completes the driving of ALS and sub-pixel. Compared with Figure 5 the display panel in the related art, the display panel of the present application makes full use of the blank driving time of the two data lines on the left and right to complete the driving of the photosensitive modules arranged at the left and right borders of the panel, and does not require additional gate time.

[0079] Referring to Figure 7As shown, it is a driving timing diagram of another display panel 10 of the present application. In some embodiments of the present application, in addition to providing photosensitive modules on the left and right sides of the display panel, photosensitive modules are also provided on the upper and lower sides of the display panel. In terms of driving timing, one more row of gate driving signals, namely gate0 and gate n+1, needs to be added to the first and last rows of the display panel. In this embodiment, the display panel 10 adopts progressive scanning driving. When Gate0 is turned on, the photosensitive module 200 in the first row is driven. The S1 line drives ALS_01, and the S2 line drives the data ALS_02, and so on. Each data line serves as a photosensitive data line. When Gate0 is turned off and Gate1 is turned on, the first pixel row is driven. At this time, the data line S1 drives R11 in the display area 10a, the data line S2 drives the sub-pixel G11, and the data line Sn is connected to the photosensitive module ALS_1m. Therefore, when the first pixel row is turned on, the data line Sn serves as a photosensitive data line to drive the photosensitive module ALS_1m. And so on. When Gate3 is turned on, the data line S1 serves as a photosensitive data line to drive the photosensitive module ALS_11 until gate n+1 is turned on, the S1 line drives ALS_n1, and the S2 line drives the data ALS_n2.

[0080] It should be noted that the number of photosensitive modules can also be adjusted according to actual needs, referring to Figure 8 As shown, it is a driving timing diagram of another display panel 10 of the present application. In some other embodiments of the present application, in addition to providing photosensitive modules on the left and right sides of the display panel, photosensitive modules are also provided on the upper and lower sides of the display panel, and the photosensitive modules on the upper and lower sides are arranged at intervals. The difference between the display panel in this embodiment and the display panel in the previous embodiment lies in the different numbers of photosensitive modules on the upper and lower sides. Therefore, the driving timing of the display panel in this embodiment is basically the same as that in the previous embodiment, and the present application will not elaborate here.

[0081] For the display panel in the above embodiment, compared with the panel design without the photosensitive module 200, only the time of 2 rows of Gates needs to be added in terms of driving timing. The opening time of these 2 rows of Gates can share the dummy CK design in the driving timing of the display panel 10. For the photosensitive module 200 existing in each other row, the Gate driving time can be shared with the sub-pixel 100 without adding extra driving time. Therefore, this solution can drive the photosensitive module 200 almost without affecting the display driving time to obtain ambient light parameters.

[0082] It should be noted that although some of the above embodiments are described based on the display panel 10 with a zig-zag arrangement, the photosensitive module of the present application is not limited to being applied in the zig-zag arrangement. Other display panels with a similar zig-zag arrangement having blank driving time in the sub-pixel rows can also adopt a similar photosensitive module setting method. The zig-zag arrangement can improve the brightness uniformity and visual effect of the display panel 10. By arranging the light sources in a staggered manner, the gap between adjacent light sources in the backlight module can be reduced, thereby reducing the problem of uneven brightness. This arrangement can also reduce the complexity of the driving circuit and improve the efficiency of the backlight module. At the same time, since the panel adopts a zig-zag arrangement, when scanning each row, there will be a data line not connected to the sub-pixel 100. That is, when there are n + 1 data lines, there are at most n sub-pixels 100 in the display area 10a. Therefore, a photosensitive module 200 can be set at the vacant data line of each row. For example, if the last data line of the first row in the display area 10a is not connected to the sub-pixel, a photosensitive module 200 is set here and connected to the last data line. Correspondingly, in the second row of the display area 10a, the first data line is not connected to the sub-pixel, and a photosensitive module 200 is designed here and connected to the first data line. And so on, two columns of photosensitive modules 200 are formed on the left and right sides of the periphery of the display area 10a of the display panel 10. At the same time, there is also a row of photosensitive modules 200 at the upper and lower positions of the periphery of the display area 10a. Finally, a circle of photosensitive modules 200 is formed on the periphery of the display area 10a. Each photosensitive module 200 can obtain the ambient light parameters of the corresponding area. Finally, the ambient light parameters of the entire display area 10a of the display panel 10 can be obtained through a circle of photosensitive modules 200.
