Liquid crystal display method

Abstract

The invention provides a display method of liquid crystal. The liquid crystal comprises a backlight source which is divided into at least two backlight source sections. The display method of the liquid crystal comprises the following steps: receiving an image signal; dividing a current image into at least two image sections according to the backlight source sections; calculating the typical brightness data of each image section; calculating the correct backlight brightness of each backlight source section according to the typical brightness data of each image section and the typical brightness data of at least one adjacent image section; adjusting the brightness of each backlight source section according to the correct backlight brightness of each section; adjusting the current image signal. In the invention, because the correct backlight brightness is simultaneously determined by the brightness of a plurality of adjacent image sections, the brightness difference of the adjacent backlight source sections is not large, and the brightness can not abruptly change, thereby similar border effect in the two adjacent image sections is prevented from occurring in the prior art and the display effect is improved.

Description

technical field [0001] The present invention relates to a display method, in particular to an image display method for a liquid crystal display device. Background technique [0002] In recent years, liquid crystal display technology has developed rapidly, but compared with other types of display technologies, liquid crystal display still has a gap in terms of contrast and color saturation. [0003] The liquid crystal screen (LCD) of a liquid crystal display device (such as a liquid crystal TV) does not emit light itself, but is a backlight display device. There is a backlight behind the LCD screen. "Block" and "Turn on" the light from the backlight to display or restore the picture. In the initial stage, as long as the liquid crystal display is powered on, the backlight is working, even if the displayed picture is a completely black picture, the backlight is still working. In other words, the backlight of the LCD TV is always shining. Due to the extremely low light transm...

Problems solved by technology

In this case, there will be a problem. If there is a large difference in image brightness between two adjacent image areas, it will inevitably cause a large difference in the brightness of the two backlight sources corresponding to the two adjacent image areas.

Then, for a complete image, there may be a sudden change in brightness at the edge of the two image areas, and the display effect is not perfect

At the same time, in order to ensure the quality of the displayed image, this method needs to process the brightness enhancement of the image, and the algorithm of this processing process is extremely complicated, and the improvement effect is relatively limited.
