The embodiment of the invention provides a brightness adjustment method and a display device. The method comprises the following steps: obtaining a target signal of which the brightness is in a presetdark field brightness interval from a to-be-processed image signal; according to the pixels of the target signal and the pixels of the to-be-processed image signal, obtaining a relative relationshipbetween the target signal and the to-be-processed image signal; wherein the relative relationship comprises a ratio of the target signal to the to-be-processed image signal, a weighting ratio of the target signal to the to-be-processed image signal or an offset relationship of the target signal to the to-be-processed image signal; determining a target brightness gain coefficient according to the relative relationship; and sending the target brightness gain coefficient and the to-be-processed image signal to a Mono Cell, and the Mono Cell adjusting the brightness of the to-be-processed image signal based on the target brightness gain coefficient, so that pixel-level control of different brightness, especially fine control of dark field brightness, can be realized.
Description
[0001] This application claims the priority of the Chinese patent application with the application number 201911423041.0 and the title of brightness adjustment method and display device submitted to the China Patent Office on December 31, 2019, the entire contents of which are incorporated in this application by reference. technical field [0002] The embodiments of the present application relate to the field of display technologies, and in particular, to a brightness adjustment method and a display device. Background technique [0003] With the continuous development of science and technology, display technology has been developed rapidly, and the penetration rate of display devices is getting higher and higher. At the same time, people's requirements for display devices are also getting higher and higher. A backlight module is an important component of a display device, including a backlight source and a display screen. The display device supplies light source through the ...
