The traditional global dimming algorithm can not significantly improve the contrast and reduce power consumption. In view of this
a classification based on image global dimming algorithm is proposed. Using VHDL language in FPGA platform
this method is implemented according to the digital high-definition display timing logic and standard. This device can change 1 9201 080 pixel HD video pixel data and backlight brightness at the same time
so as to significantly improve high-definition display resolution and reduce power consumption. Experimental results show that this device can meet the design targets
