Detailed Implementation

[0017] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0018] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0019] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0021] Currently, common pixel design schemes for LCD displays include 4-domain and 8-domain schemes.

[0022] The 8domain scheme divides a subpixel into two parts: a main subpixel and a subpixel. During driving, the main and sub are charged to different voltage levels, resulting in different brightness levels. When viewed from a wide angle, the main and sub liquid crystals within a single subpixel do not rotate in the same direction, thus providing a better cumulative visual effect for the human eye and effectively solving the color shift problem, thereby increasing the viewing angle. However, while the 8domain scheme offers a good viewing angle, it suffers from low transmittance (one subpixel requires three thin-film transistors, two capacitors, and multiple common electrode traces), significantly sacrificing transmittance.

[0023] Compared to the 8domain scheme, the 4domain scheme does not distinguish between main and subdomains, resulting in more severe color distortion when viewed from a wide angle.

[0024] Figure 1 A schematic diagram of a display panel according to an embodiment of this application is shown. For ease of explanation, only the parts relevant to this embodiment are shown, and the details are as follows: A display panel 10 includes a pixel matrix and a charging circuit.

[0025] A pixel matrix comprises multiple pixel sub-units arranged in rows and columns, such as... Figure 1 As shown, the multiple pixel subunits include multiple first pixel subunits 110 and multiple second pixel subunits 120.

[0026] The charging circuit includes multiple charging sub-circuits, each corresponding to a pixel sub-unit. For example, Figure 2As shown, the plurality of charging sub-circuits include a plurality of first charging sub-circuits 210 and a plurality of second charging sub-circuits 220; the first charging sub-circuit 210 is connected to the first pixel sub-unit 110 and is used to provide a first charging voltage to the first pixel sub-unit 110 based on the received grayscale voltage; the second charging sub-circuit 220 is connected to the second pixel sub-unit 120 and is used to provide a second charging voltage to the second pixel sub-unit 120 based on the received grayscale voltage; when the received grayscale voltages are the same, the first charging voltage provided by the first charging sub-circuit 210 is greater than the second charging voltage.

[0027] It should be noted that the higher the charging voltage, the larger the liquid crystal flip angle in the corresponding pixel sub-unit, the higher the brightness, and the smaller the viewing angle. Conversely, the lower the charging voltage, the smaller the liquid crystal flip angle in the corresponding pixel sub-unit, the lower the brightness, and the larger the viewing angle. The grayscale voltages provided to each charging sub-circuit can be different, and the specific value of the grayscale voltage is determined by the image to be displayed on the display panel 10, which will not be elaborated further in this embodiment.

[0028] A first charging voltage is provided to the first pixel sub-unit 110 through the first charging sub-circuit 210, and a second charging voltage is provided to the second pixel sub-unit 120 through the second charging sub-circuit 220. With the same grayscale voltage, the brightness of the first pixel sub-unit 110 can be greater than that of the second pixel sub-unit 120, and the viewing angle of the second pixel sub-unit 120 can be greater than that of the first pixel sub-unit 110. By mixing the first pixel sub-unit 110 and the second pixel sub-unit 120 on the same display panel 10, the brightness and darkness of the pixel sub-units are separated, allowing the display panel 10 to simultaneously balance display brightness and viewing angle.

[0029] It is understood that a pixel subunit can be used to emit light of one color, and multiple pixel subunits emitting different colors can be combined to form a pixel unit. In some embodiments, a pixel unit includes at least one red pixel subunit, at least one green pixel subunit, and at least one blue pixel subunit. This embodiment does not limit all first pixel subunits 110 to be pixel subunits of the same color, nor does it limit all second pixel subunits 120 to be pixel subunits of the same color; the colors of each first pixel subunit 110 and each second pixel subunit 120 are set according to actual needs.

[0030] In a pixel matrix, pixel sub-units located in the same column can emit the same color. For example, a column of red pixel sub-units, a column of green pixel sub-units, and a column of blue pixel sub-units are arranged alternately along the row direction of the pixel matrix.

[0031] In one embodiment, in the same row of pixel sub-units, the first pixel sub-unit 110 and the second pixel sub-unit 120 are arranged alternately in sequence.

[0032] Since the overall brightness of the first pixel subunit 110 is greater than that of the second pixel subunit 120, by having the first pixel subunit 110 and the second pixel subunit 120 arranged alternately, the brightness distribution in the same row of pixel subunits becomes more uniform.

[0033] In one embodiment, in the same column of pixel sub-units, the first pixel sub-unit 110 and the second pixel sub-unit 120 are arranged alternately in sequence.

[0034] By arranging the first pixel sub-unit 110 and the second pixel sub-unit 120 alternately, the brightness distribution of the same column of pixel sub-units can be made more uniform.

[0035] By having the first pixel subunit 110 and the second pixel subunit 120 alternately arranged in the same row of pixel subunits, and by having the first pixel subunit 110 and the second pixel subunit 120 alternately arranged in the same column of pixel subunits, the brightness distribution on the entire display panel 10 can be made more uniform. This can prevent multiple first pixel subunits 110 from being set together or multiple second pixel subunits 120 from being set together, thereby avoiding bright spots, bright lines, dark spots and dark lines on the display panel 10.

[0036] In one embodiment, the first charging sub-circuit 210 includes a first charging switch T1 and a first pixel capacitor C1; the first terminal of the first charging switch T1 is used to connect to the grayscale voltage, the second terminal of the first charging switch T1 is connected to the first terminal of the first pixel capacitor C1, the control terminal of the first charging switch T1 is used to connect to the scanning voltage, and the second terminal of the first charging switch T1 is connected to the first common voltage terminal Vcom.

[0037] It should be noted that when displaying an image, the display panel 10 typically uses a line-by-line scanning method to sequentially illuminate each pixel sub-unit. Specifically, a scanning voltage can be provided to the first charging switch T1 to turn it on, and then the first pixel capacitor C1 can be charged by the first charging switch T1 based on the grayscale voltage until the first charging switch T1 is turned off. The voltage on the first pixel capacitor C1 is the first charging voltage provided to the first pixel sub-unit 110, so that the first pixel sub-unit 110 uses the first charging voltage to control the liquid crystal flipping in the first pixel sub-unit 110.

[0038] By controlling the timing and sequence of the scanning voltage, and in conjunction with the grayscale voltage, the configuration of the first charging voltage for the first pixel subunit 110 in the entire display panel 10 can be achieved.

[0039] The voltage on the first common voltage terminal Vcom is equal to the voltage corresponding to the 0 gray level of the pixel sub-unit.

[0040] In one embodiment, the second charging sub-circuit 220 includes a second charging switch T2, a third charging switch T3, and a second pixel capacitor C3. The first terminal of the second charging switch T2 is used to connect to a grayscale voltage, the second terminal of the second charging switch T2 is connected to the first terminal of the second pixel capacitor C3, the control terminal of the second charging switch T2 is used to connect to a scanning voltage, the second terminal of the second pixel capacitor C3 is connected to a first common voltage terminal Vcom, the first terminal of the third charging switch T3 is connected to the first terminal of the second pixel capacitor C3, the second terminal of the third charging switch T3 is connected to a second common voltage terminal T3Vcom, and the control terminal of the third charging switch T3 is used to connect to a scanning voltage. The second charging switch T2 and the third charging switch T3 are configured to not be fully turned on when a scanning voltage is received (i.e., the on-resistance is not 0 or approximately equal to 0).

[0041] Understandably, similar to the first charging sub-circuit 210, by controlling the timing and sequence of providing the scanning voltage, in conjunction with the grayscale voltage, the configuration of the second charging voltage for the second pixel sub-unit 120 in the entire display panel 10 can be achieved. Unlike the first pixel sub-unit 110, the second charging switch T2 and the third charging switch T3 in the second pixel sub-unit 120 are configured not to be fully turned on when the scanning voltage is received. Therefore, a certain voltage division will occur between the second charging switch T2 and the third charging switch T3, affecting the voltage ultimately applied to the second pixel capacitor C3.

[0042] Even if the same grayscale voltage is provided to the first pixel subunit 110 and the second pixel subunit 120, the final first charging voltage will be greater than the second charging voltage, so that the liquid crystal flip angle, brightness and viewing angle of the corresponding first pixel subunit 110 and second pixel subunit 120 are different, thereby achieving complementarity.

[0043] The second common voltage terminal T3Vcom can be configured according to actual needs. The second charging voltage increases as the voltage of the second common voltage terminal T3Vcom increases. The resistance values ​​of the second charging switch T2 and the third charging switch T3 can be adjusted by changing the structure of the corresponding thin-film transistor (e.g., channel length, ion doping concentration, etc.), which can be set according to actual needs, and will not be elaborated further in this embodiment.

[0044] In one embodiment, when the second charging switch T2 and the third charging switch T3 receive a scanning voltage, the ratio of the resistance of the second charging switch T2 to the resistance of the third charging switch T3 is between 1:3 and 1:4.

[0045] Understandably, the scanning voltage can prevent the second charging switch T2 and the third charging switch T3 from being fully turned on. The second charging voltage can be adjusted by configuring the ratio of the resistance of the second charging switch T2 to the resistance of the third charging switch T3.

[0046] Specifically, when the resistance ratio of the second charging switch T2 to the resistance ratio of the third charging switch T3 is 1:3, the second charging voltage is approximately 3 / 4 of the grayscale voltage; when the resistance ratio of the second charging switch T2 to the resistance ratio of the third charging switch T3 is 1:4, the second charging voltage is approximately 4 / 5 of the grayscale voltage.

[0047] In some embodiments, the first charging switch T1, the second charging switch T2, and the third charging switch T3 all include thin-film transistors.

[0048] In one embodiment, the first charging sub-circuit 210 further includes a first energy storage capacitor C2, and the second charging sub-circuit 220 further includes a second energy storage capacitor C4.

[0049] The first terminal of the first energy storage capacitor C2 is connected to the first terminal of the first pixel capacitor C1, such as Figure 2 , Figure 3 As shown, the second end of the first energy storage capacitor C2 is connected to the second common voltage terminal T3Vcom or the third common voltage terminal AVcom, the first end of the second energy storage capacitor C4 is connected to the first end of the second pixel capacitor C3, and the second end of the second energy storage capacitor C4 is connected to the second common voltage terminal T3Vcom or the third common voltage terminal AVcom.

[0050] The voltage at the third common voltage terminal AVcom must be at least less than the grayscale voltage. The voltage at the third common voltage terminal AVcom can be equal to the voltage at the second common voltage terminal T3Vcom.

[0051] It is understandable that after the first pixel capacitor C1 and the second pixel capacitor C3 are charged, the electrical energy on the first pixel capacitor C1 and the second pixel capacitor C3 will be slowly lost through leakage, especially the electrical energy on the second pixel capacitor C3 will be lost through the third charging switch T3.

[0052] By setting the first energy storage capacitor C2 and the second energy storage capacitor C4, the total amount of stored electrical energy can be increased, the voltage drop rate on the first pixel capacitor C1 and the second pixel capacitor C3 can be reduced, and the display effect can be guaranteed.

[0053] With the second terminal of the first energy storage capacitor C2 connected to the second common voltage terminal T3Vcom, and the second terminal of the second energy storage capacitor C4 connected to the second common voltage terminal T3Vcom, the wiring related to the third common voltage terminal AVcom can be omitted, which can further improve the aperture ratio.

[0054] In one embodiment, the display panel 10 further includes multiple data lines 300, and the charging electronic circuit is connected to at least one data line 300. The data lines 300 are used to transmit grayscale voltage.

[0055] The data trace 300 can extend along the column direction of the pixel matrix. Each column of pixel sub-units has a corresponding data trace 300. The same column of pixel sub-units are all connected to the same corresponding data trace 300 to obtain grayscale voltage from the data trace 300.

[0056] In one embodiment, the display panel 10 further includes multiple scan lines 400, and the charging electronic circuit is connected to at least one scan line 400. The scan line 400 is used to transmit scan voltage.

[0057] The scan trace 400 can extend along the row direction of the pixel matrix. Each row of pixel sub-units has a corresponding scan trace 400. Pixel sub-units in the same row are all connected to the same corresponding scan trace 400 to obtain scan voltage from the scan trace 400.

[0058] It is understandable that each scan line 400 will provide scan voltage row by row so that the charging switch of each pixel sub-unit will be turned on row by row. Then, according to the pixel sub-unit whose charging switch is turned on, the gray level voltage on each data line 300 can be configured, thereby realizing the individual configuration of the charging voltage of each pixel sub-unit.

[0059] In the same row of pixel sub-units, the first pixel sub-unit 110 and the second pixel sub-unit 120 are arranged alternately. Similarly, in the same column of pixel sub-units, only three switching devices are needed for every two adjacent pixel sub-units. In contrast, the traditional 8-domain scheme requires at least six switching devices for every two adjacent pixel sub-units. Therefore, the display panel 10 in this embodiment has a higher aperture ratio and higher transmittance. The embodiment requires relatively fewer capacitors for charging, making charging easier and facilitating high refresh rates and high resolutions. Furthermore, only the third charging switch T3 in this embodiment generates relatively large leakage current, resulting in lower power consumption compared to the 8-domain scheme.

[0060] Compared to the 4domain scheme, this embodiment implements brightness and darkness separation of pixel sub-units, enabling the display panel to simultaneously consider display brightness and viewing angle without needing to change the charger model to avoid flickering. Since the voltage regulation of the second charging voltage is achieved through voltage division by the second charging switch T2 and the third charging switch T3, the algorithm and data of the 4domain scheme can be directly applied to drive the display panel 10.

[0061] While DLG and HSR technologies can improve refresh rates, they can also cause some adjacent pixel sub-units to have identical brightness, leading to a decrease in resolution and a reduction in display quality. However, when the display panel 10 of this embodiment implements DLG and HSR technologies, it can achieve this through hardware circuitry, ensuring that even with the same grayscale voltage, there will be a brightness difference between adjacent pixel sub-units. This, in turn, can improve the display quality and resolution to a certain extent.
