Display device and white balance adjusting method of photosensitive element of display device

A white balance adjusting method of a photosensitive element of a display device, wherein the display device comprises a display panel which comprises a photosensitive region, the photosensitive element disposed on a side of the display panel and disposed corresponding to the photosensitive region, and a driver integrated circuit (IC) electrically connected to the display panel and the photosensitive element;

• wherein the white balance adjusting method of the photosensitive element comprises following steps:
• obtaining a first white balance imaging parameter which is color parameters of a preset image collected by the photosensitive element of the display device under a preset light source by the driver IC;
• obtaining a second white balance imaging parameter which is color parameters of a preset image collected by a photosensitive element of a typical display device under the preset light source by the driver IC, the typical display device is a sample display device of a preset number of sample display devices selected from a batch of display devices, and a first white balance imaging parameter of the sample display device is within a preset threshold value of an average of all first white balance imaging parameters of the preset number of the sample display devices;
• and
• performing a white balance compensation on image data collected by the photosensitive element of the display device according to a deviation between the first white balance imaging parameter of the photosensitive element of the display device and the second white balance imaging parameter of the photosensitive element of the preset typical display device being preset by the driver IC.
