一种背光源的动态调光显示控制方法和装置
摘要：
本发明提出了一种背光源的动态调光显示控制方法和装置，方法包括：根据待显示图像的灰阶确定各个背光区域的背光统计值；根据背光统计值进行分段位移确定背光设定值；获取背光模块的背光源扩散传输参数；根据背光源扩散传输参数和各个背光区域的背光设定值计算各个像素点的等效背光亮度；根据各个像素点的等效背光亮度计算对应的补偿图像；以及控制背光模块根据背光设定值点亮背光源，以及控制液晶面板根据补偿图像进行图像显示。即可恰当调节背光亮度，又能准确地计算每个像素点的等效背光，从而获得相应的LCD补偿图像，实现与全背光显示的相同的甚至更优的显示效果。
摘要（英）：

A display control method and apparatus of backlight sources, and a display device are provided. The method includes: determining a set backlight value of each backlight area according to a grayscale of an image to be displayed; determining an equivalent backlight luminance of each pixel point according to backlight source diffusion transmission parameter of the backlight module of the display device and the set backlight value of each backlight area; determining a compensation image according to the equivalent backlight luminance of each pixel point; and controlling the backlight module to turn on the backlight sources according to the set backlight value of each backlight area, and controlling the display panel to display the image according to the compensation image.
