Problems solved by technology
[0004] However, the existing gray-scale voltage adjustment method generally adjusts the gray-scale voltage stored in the register through continuous experiments. Although it can adjust the gray-scale voltage, it needs continuous experiments, which makes the process of adjusting the gray-scale voltage more complicated. , and the adjustment efficiency is low

The invention discloses a gray-scale voltage adjustment device and method, a display driving device and a display device, which relate to the field of display technology and are used to reduce the workload during gray-scale voltage adjustment, thereby simplifying the gray-scale voltage adjustment process. The gray scale voltage adjustment method is based on at least one binding point of the three primary colors corresponding to the gray scale brightness value, and the gray scale voltage corresponding to the three primary colors under the corresponding binding point to perform fitting, based on the fitting result, according to the three primary colors in the target image The target luminance of a gray scale is checked, and the corresponding gray scale voltage is queried to drive the display device to display the target image. The gray scale voltage adjusting device is used to realize the above gray scale voltage adjusting method. The gray scale voltage adjustment device and method, the display driving device and the display device provided by the present invention are used in gray scale voltage adjustment.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a gray scale voltage adjustment device and method, a display driving device and a display device. Background technique [0002] An organic electroluminescence display device is a self-luminous display device without a backlight, and each organic electroluminescence device realizes light emission. Since the organic electroluminescent display device does not need a backlight to provide a backlight, the organic electroluminescent display device is relatively thin compared to the traditional liquid crystal display device, which is conducive to the development of thinner and lighter display devices, which also makes the organic electroluminescent display device subject to Users welcome. [0003] In order to improve the display image quality of the organic electroluminescent display device, generally before shipment, the gray scale voltage of the organic electroluminescent di...
