Embodiment Construction
[0037] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.
[0038] The traditional display drive architecture is to input the OVDD and OVSS power required by the panel through the Source COF Bypass (the pins of the source flexible circuit board), and cooperate with the GOA circuit to realize the scan drive. Most products are unilateral input, which is conducive to product form design. and low cost. However, in the traditional display drive architecture, when the display is displaying a picture with a high load, due to the large current in the panel, there is a voltage drop (IRDrop) caused by obvious impedance on the OVDD and OV...

The invention relates to a display compensation method, device and system and display equipment. The method comprises the following steps: acquiring to-be-compensated display data; performing image recognition processing on the to-be-compensated display data to obtain display feature information; when the display feature information meets a picture compensation condition, processing the to-be-compensated display data to obtain a panel load coefficient; processing the panel load coefficient and the display characteristic information to obtain a voltage drop compensation coefficient; and performing compensation processing on the to-be-compensated display data according to the voltage drop compensation coefficient to obtain compensated display data, thereby realizing compensation of display uniformity. The differential dynamic voltage drop compensation coefficient related to the display content is formulated by combining an image recognition technology and regional load capacity estimation, the to-be-compensated display data is compensated according to the voltage drop compensation coefficient, the compensated display time is output, a picture is uniformly displayed, and the display quality is improved. And the display uniformity of the display is greatly improved.
Description
technical field [0001] The present application relates to the technical field of display processing, and in particular, to a display compensation method, apparatus, system and display device. Background technique [0002] The continuous development and progress of display technologies such as LCD (Liquid Crystal Display, liquid crystal display), AMOLED (Active-matrix organic light-emitting diode, active matrix organic light-emitting diode panel) and Mini LED direct display bring increasingly rich display products and more colorful display applications. As one of the core indicators of the display, the uniformity of the display directly affects the performance of the display product. However, due to the influence of the process technology and other factors, the improvement of the uniformity of the display faces many challenges. The traditional solutions to improve the display uniformity include electrical detection. Compensation, Demura (brightness compensation) optical comp...
