It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart illustrating a compensation method for a display panel according to an embodiment of the present invention. The present embodiment is applicable to a case where the display panel has uneven brightness of a display screen during use and needs to be compensated, and the method may be performed by a compensation apparatus of the display panel, as shown in fig. 1, and the compensation method of the display panel includes:

For example, during the manufacturing process of the display panel, an external compensation method may be adopted to compensate the light emitting brightness of the display panel, that is, a method of sensing the optical characteristics of the pixels by an external device and then compensating. When the optical characteristics of the sensing pixels are compensated externally, the display panel can be photographed through devices such as a CCD and the like to obtain the luminous brightness of the display panel, and compensation data required by the uneven brightness of the display panel is calculated through the luminous brightness and the target luminous brightness, namely the compensation data of the display panel. The compensation data of the display panel is mainly used for compensating the brightness unevenness of the display panel caused by the process and other reasons in the manufacturing process of the display panel. The compensation data of the display panel can be stored in the compensation data storage unit of the display panel through burning, and the compensation data in the compensation data storage unit is called to compensate the display panel in the display process of the display panel.

specifically, the initial display frame may be a detection display frame used by the display panel manufacturing process to detect the display panel. In the manufacturing process of the display panel, the display panel has a phenomenon of uneven brightness when displaying an initial display picture due to a manufacturing process and the like. The method comprises the steps of obtaining an initial display picture of a display panel, processing image data to obtain display data of the display panel, and determining compensation data needing to be compensated in the manufacturing process of the display panel according to the display data and a target pixel value.

specifically, after the current display screen of the display panel is acquired again, the acquired current display screen may be subjected to data processing to determine the latest display data of the display panel. The updated display data may include compensation data for each pixel. After the latest display data of the display panel is determined, the latest compensation data of the display panel may be determined according to a difference between the target pixel value and the latest display data of the display panel. The latest compensation data is obtained on the basis of the increase of the use time of the display panel, so that the latest compensation data of the display panel can compensate the increase of the use time of the display panel, and the display panel is further aged to cause the uneven brightness of the display panel.
