[0024] It should be noted that in this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and drawings of this application are used to distinguish similar objects, not to describe a specific order or sequence.

[0025] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner. Unless otherwise specified, the following embodiments and features described herein can be combined with each other.

[0026] In the development and design of existing LCD panels, the coupling between the source line and the common voltage (VCOM) of the panel's common electrode causes VCOM to be stretched. When VCOM is stretched, it deviates from the correct common voltage, causing a shift in the liquid crystal deflection electric field strength. This leads to incorrect liquid crystal deflection and crosstalk, resulting in image retention, crosstalk, or flickering in the LCD panel display.

[0027] To address the aforementioned technical problems, this application provides a voltage compensation circuit and a display panel to resolve issues such as image retention, crosstalk, or fluctuations in the displayed image caused by VCOM deviation. (Reference) Figure 1 The diagram shown is a schematic representation of the structure of a display panel in some embodiments of this application. The display panel 1 includes a screen 10 and a voltage compensation circuit 20. The voltage compensation circuit 20 is used to compensate for the VCOM of the display panel 1 to prevent the image displayed on the screen 10 from being stretched due to VCOM, resulting in image retention, crosstalk, or flicker.

[0028] In some embodiments of this application, the display panel 1 includes, but is not limited to, a thin-film transistor liquid crystal display (TFT-LCD) panel, a twisted nematic (TN) panel, a vertical alignment (VA) panel, an in-plane switching (IPS) panel, and a liquid crystal display panel.

[0029] refer to Figure 2 The diagram shown is a schematic representation of a voltage compensation circuit in some embodiments of this application. The voltage compensation circuit 20 includes a panel driving module 21, a driving chip 22, and a common electrode 23. In some embodiments of this application, the panel driving module 21 is connected to the driving chip 22, and the driving chip 22 is connected to the common electrode 23.

[0030] In some embodiments of this application, the driver chip 22 is provided with a voltage adjustment circuit 221, which includes a feedback resistor network 2211 and a compensation voltage generation module 2212. The panel driver module 21 is used to detect each frame displayed on the screen 10 of the display panel 1, determine the voltage compensation ratio based on the frame, and send the voltage compensation ratio to the driver chip 22. The driver chip 22 adjusts the configuration resistor of the feedback resistor network 2211 according to the voltage compensation ratio. The compensation voltage generation module 2212 outputs an adjusted voltage according to the configuration resistor, and adjusts the voltage of the common electrode 23 according to the adjusted voltage, thereby compensating for the VCOM of the display panel 1.

[0031] In some embodiments of this application, the panel driving module 21 detects each frame displayed on the display panel 1 according to the frame rate. The panel driving module 21 determines the voltage compensation ratio corresponding to the frame type by looking up a scaling factor table based on the frame type. In some embodiments of this application, the scaling factor table includes different frame types and voltage compensation ratios, with each frame type corresponding to a voltage compensation ratio. For example, refer to... Figure 3 The diagram shown illustrates a magnification ratio table provided in some embodiments of this application. In the magnification ratio table, the images include types such as 31-grayscale lake surface contrast test (CT) images, 64-grayscale lake surface CT images, and 127-grayscale lake surface CT images. The voltage compensation ratio corresponding to the 31-grayscale lake surface CT image is 1x, the voltage compensation ratio corresponding to the 64-grayscale lake surface CT image is 2x, and the voltage compensation ratio corresponding to the 127-grayscale lake surface CT image is 3x. It should be noted that the magnification ratio table in the embodiments of this application is merely an example. The magnification ratio table can include more image types and voltage compensation ratios as needed, and this application does not impose any limitations on this.

[0032] In some embodiments of this application, the panel driving module 21 determines the pixel region in the image that affects the common electrode 23, and determines the voltage compensation ratio based on the size of the pixel region, the position of the pixel region in the image, and the grayscale value within the pixel region.

[0033] refer to Figure 4 The diagram shown is a schematic representation of a pixel region in an image provided in some embodiments of this application. In some embodiments of this application, the panel driving module 21 determines the size of the pixel region based on the number of pixels within the pixel region. For example, refer to... Figure 4 The panel driving module 21 determines the size of the pixel region as x*y based on the pixel coordinates of the pixels in the pixel region, where x is the number of pixels in the width direction of the pixel region and y is the number of pixels in the height direction of the pixel region.

[0034] In some embodiments of this application, the screen can be divided into multiple screen regions, each corresponding to a region coefficient. The region coefficient is larger for screen regions located closer to the center of the screen and smaller for screen regions located closer to the edges of the screen. In some embodiments of this application, the panel driving module 21 determines the screen region where the pixel region is located based on the pixel coordinates of the pixels within the pixel region, and determines the region coefficient corresponding to the screen region as the region coefficient of the pixel region.

[0035] In some embodiments of this application, each pixel or pixel region of the image corresponds to a pixel coefficient, wherein the larger the grayscale value of a pixel or pixel region, the larger the corresponding pixel coefficient. The panel driving module 21 determines the pixel coefficient corresponding to the pixel region based on the grayscale value of the pixels within the pixel region.

[0036] In some embodiments of this application, the panel driving module 21 uses the product of the pixel area size, the pixel area coefficient, and the pixel coefficient of the pixel area as the voltage compensation ratio of the pixel area.

[0037] In some embodiments of this application, after determining the voltage compensation ratio, the panel driving module 21 sends the voltage compensation ratio to the driving chip 22 via frame configuration.

[0038] refer to Figure 5 The diagram shown illustrates a voltage adjustment circuit 221 provided in some embodiments of this application.

The compensation voltage generation module 2212 includes a non-inverting input terminal 2213, an inverting input terminal 2214, and a voltage output terminal 2215. The non-inverting input terminal 2213 is connected to a common electrode. The inverting input terminal 2214 is connected to the voltage output terminal 2215 through the feedback resistor network 2211. In some embodiments of this application, the compensation voltage generation module 2212 is an amplifier circuit.

[0039] In some embodiments of this application, the feedback resistor network 2211 includes at least one first resistor R1 and at least one second resistor R2 interconnected. The first resistors R1 are connected via a first switching circuit 51, and the second resistors R2 are connected via a second switching circuit 52. The resistance values ​​of the first resistors R1 and the second resistors R2 are different. In some embodiments of this application, the driver chip 22 adjusts one of the first resistors R1 or the second resistor R2 to be the configuration resistor of the feedback resistor network 2211 according to the voltage compensation ratio. For example, the driver chip 22 closes the switch of the second switching circuit 52 corresponding to any second resistor R2, and selects a first resistor as the configuration resistor according to the voltage compensation ratio, wherein the ratio of the second resistor to the configuration resistor is the same as the voltage compensation ratio. As another example, the driver chip 22 closes the switch of the first switching circuit 51 corresponding to any first resistor R1, and selects a second resistor as the configuration resistor according to the voltage compensation ratio, wherein the ratio of the configuration resistor to the first resistor is the same as the voltage compensation ratio.

[0040] In some embodiments of this application, the driver chip 22 adjusts the first resistor R1 and the second resistor R2 to the configuration resistors according to the voltage compensation ratio. For example, the driver chip 22 selects a target second resistor from among the various second resistors and a target first resistor from among the various first resistors according to the voltage compensation ratio, and uses the target first resistor and the second target resistor as configuration resistors, wherein the ratio of the second resistor to the first resistor is the same as the voltage compensation ratio. In some embodiments of this application, the driver chip 22 adjusts the configuration resistor of the feedback resistor network 2211 according to the voltage compensation ratio, the voltage output terminal of the compensation voltage generation module 2212 outputs an adjustment voltage corresponding to the voltage compensation ratio, and adjusts the voltage of VCOM according to the adjustment voltage.

[0041] The voltage compensation circuit in this embodiment can dynamically adjust VCOM according to each frame displayed on the display panel, which can solve the problem of image retention, crosstalk or fluctuation caused by VCOM deviation in the display panel, and at the same time optimize the display effect of each frame.

[0048] In step S603, the compensation voltage generation module of the driving chip outputs an adjustment voltage according to the configuration resistor, and adjusts the voltage of the common electrode according to the adjustment voltage.

[0049] In some embodiments of this application, sending the voltage compensation ratio to the driver chip includes: the panel driver module sending the voltage compensation ratio to the driver chip via a frame configuration method.
