摘要： The present invention offers a display method, which can adjust the brightness of backlight by the brightness correction of the backlight, thereby not only decreasing the power consumption, but also solving the problem of blinking backlights. Especially, the display method of the present invention comprises: receiving an image signals, calculating the typical brightness of said image signal, calculating the brightness correction of the backlight according to the typical brightness of said image signal and the brightness of the backlight, adjusting the brightness of the backlight according to the brightness correction of the backlight, and adjusting said image signal. The display method of the present invention is correcting the image gray and contrast by applying the algorithm of slow changing of backlight according to the brightness scale of the input image, while adjusting the brightness of the backlight, therefore unchanging or increasing the subjective image effect, preventing the blinking of the backlight and improving the quality of the display.

摘要： The present invention discloses a liquid crystal display method, which can adjust the brightness of different segments of backlight according to the different images. Especially, the present invention discloses a liquid crystal display method, which includes: receiving a image signal; analyzing the image signal; dividing the image into at least two image segments according to the analysis result of the image signal; dividing the backlight into at least two backlight segments according to the division result of the image; adjusting the brightness of the backlight in each backlight segment; adjusting the image signal in each image segment. The liquid crystal display method of the present invention divide the image and the backlight according to the image signal, while adjusting the brightness of the image and backlight in each segment to not only decrease the power consumption of the liquid crystal display, but also increase the contrast of the image signal, thereby improving the effect of liquid crystal display.
