Problems solved by technology
However, adopting the design method of the camera under the screen, on the basis of increasing the screen-to-body ratio of the display device, puts forward higher requirements on the light transmittance at the position where the photosensitive element is set in the display panel, and the photosensitive element is set in the display panel. The problem of brightness uniformity during display at the position and the position where no photosensitive element is installed also needs to be solved urgently

The invention provides a gamma debugging device and method for a display panel and a display method, relates to the technical field of display, and is used for carrying out simple and accurate gamma debugging on the display panel and improving the brightness uniformity of the display panel. A first display area of the display panel comprises a light-transmitting area between two adjacent pixels. Pixels in a first area of the second display area include first pixels and second pixels. The density of the first pixels and the density of the second pixels are the same as the density of the pixelsand the density of the light-transmitting areas in the first display area, and the arrangement mode is the same as the arrangement mode of the pixels and the light-transmitting areas in the first display area. A driving module in the gamma debugging device controls a first pixel to emit light at a first gray-scale voltage and a second pixel not to emit light. The absolute value of the difference between the first actual brightness of the first region and the target brightness under the first gray-scale voltage is less than or equal to a preset threshold. The storage module stores the first actual brightness and the first gray-scale voltage as gamma debugging data of the first display area.
Description
【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a gamma debugging device, a gamma debugging method and a display method for a display panel. 【Background technique】 [0002] With the increase of users' demand for diversified use of display devices and the emergence of design requirements for high screen-to-body ratio of display devices, the design of under-screen cameras has emerged, that is, the photosensitive elements such as cameras are embedded in the backlight of the display panel. side to maximize the screen-to-body ratio of the display device. However, the design method of the camera under the screen, on the basis of increasing the screen-to-body ratio of the display device, puts forward higher requirements for the light transmittance at the position where the photosensitive element is set in the display panel, and the photosensitive element is set in the display panel. The problem of brightness uniformity du...
