Embodiment Construction
[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0029] As mentioned in the background art, the conventional display panel including the light-transmitting display area has the problem of uneven display on the screen body. The inventor found that the reason for the above problems is that the camera, fingerprint recognition module and other structures are usually arranged under the display panel, and in order to ensure the normal operation of the camera and fingerprint recognition module, the display panel corresponds to the camera and fingerprint recognition unit...

The embodiment of the invention discloses a display panel and a debugging method thereof. The method comprises the steps of: enabling a driving module to adjust a data voltage corresponding to the preset sub-pixel under the preset gray scale according to the difference between the light emitting brightness of the first pixel group and the light emitting brightness of the second pixel group sensedby the light sensing module so as to determine the target data voltage of the preset sub-pixel under the preset gray scale; adjusting the luminance of the preset sub-pixels in the first display area according to the target data voltage; as the target data voltage meets the condition that the difference between the luminance of the first pixel group and the luminance of the second pixel group underthe preset gray scale is smaller than the preset luminance threshold value, ensuring that the difference between the luminance of the preset sub-pixels in the first display area and the luminance ofthe second pixel group in the second display area is small. The display uniformity of the preset sub-pixels in the first display area and the second display area can be improved, and then the displayuniformity of the first display area and the second display area can be improved.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a display panel and a debugging method thereof. Background technique [0002] In the structural design of the display panel, due to the need to install a camera, fingerprint recognition module, etc., a light-transmitting display area is usually set in the display panel, resulting in uneven display of the existing display panel including the light-transmitting display area. question. Contents of the invention [0003] The invention provides a display panel and a debugging method thereof, so as to reduce the brightness difference between the first display area and the second display area under the same gray scale and improve display uniformity. [0004] In a first aspect, an embodiment of the present invention provides a display panel, which is divided into a first display area and a second display area, wherein the first display area is a light-transm...
