Embodiment Construction

[0010] The present invention divides the backlight module by region division, so that the display can adjust the luminance of the backlight module regionally, and cooperate with the converted picture signal to maintain the original brightness and chromaticity of the picture. The purpose of region segmentation is to distinguish the foreground and background of the picture, that is, to distinguish regions with different brightness. The area of ​​each area need not be the same or symmetrical. The more the number of areas, the better the effect of area-based control of the brightness of the backlight module, and the more power can be saved, but the cost is relatively higher.

[0011] Please refer to FIG. 1A , FIG. 1B and FIG. 1C , which are schematic diagrams of region division according to the present invention. Referring to FIG. 1A , the backlight module is evenly divided into four backlight areas. In FIG. 1B , the backlight module is divided into a central backlight area and ...

Abstract

This invention discloses a region segmentation display and its display method including at least a backlight module, a segmenting unit, a signal process unit and a variable unit, in which, the backlight module has several backlight regions and each backlight region includes a brightness unit with a primary standard brightness value, the segmentation unit segments the input picture signals into several output picture signals, the variable unit changes the primary standard brightness value to the output brightness value based on the regional signals matched to the corresponding primary standard value to present a brightness and a color, and the output brightness value matched with the corresponding output picture signal maintains the brightness and color approaching to the original one.

Description

technical field [0001] The present invention relates to a display and its display method, in particular to an area division display and its display method. Background technique [0002] The backlight module of a traditional display has a fixed luminance, so when displaying pictures with different brightness, the luminance of the backlight module cannot be changed, and the picture with low brightness is still displayed at the same luminance, resulting in waste of electric energy. In the prior art, Philips uses Adaptive Dynamic Image Control (ADAC) in conjunction with the In Plane Switching Mode (In Plane Switching Mode) liquid crystal display to dynamically adjust the overall brightness of the backlight module according to the color scale distribution of the screen. , that is, when the screen brightness is high, the backlight module is adjusted to a larger brightness value, and when the screen brightness is low, the backlight module is adjusted to a smaller brightness value. ...
