Abstract

The embodiment of the invention provides an image display method and device, electronic equipment and a readable storage medium, and relates to the technical field of image display. The method comprises the steps of obtaining a primary color component maximum value and a primary color component average value in a current frame image according to three primary color components of each pixel point in the current frame image to be displayed; performing weighted summation on the obtained values to obtain a target brightness reference value; obtaining a target pulse width modulation duty ratio according to a corresponding relation between a preset brightness reference value and the pulse width modulation duty ratio and the target brightness reference value; and adjusting the backlight brightness of the backlight module by adopting the target pulse width modulation duty ratio, and displaying the current frame image. Therefore, the backlight brightness is adjusted according to the target brightness reference value corresponding to the actual brightness of the current frame image, and the problems of poor backlight control effect and poor display effect caused by large deviation between the calculated brightness and the actual brightness of the frame image can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of screen display, and in particular, to an image display method, device, electronic equipment, and readable storage medium. Background technique [0002] At present, the backlight control of a display device (for example, a liquid crystal television) generally first obtains the brightness of a frame image according to a brightness equation, and then adjusts the brightness of the backlight according to the brightness. Wherein, the brightness equation is: Y=0.30R+0.59G+0.11B. However, in some cases, there is a large deviation between the luminance calculated by the above method and the actual luminance of the frame image, which will lead to poor control effect of backlight luminance and poor display effect. For example, the R (red) component and G (green) component of a frame image are very small, and the B (blue) component is very large, and the actual brightness of the frame image is much greater...
