Embodiment Construction

[0037] According to the array arrangement of the backlight sources of the display device, the invention pre-sets the display area division parameters for the data to be displayed, so that the data to be displayed is subsequently divided into M data blocks to be displayed according to the display area division parameters. The present invention also presets target display parameters. After subsequent display analysis is performed on the divided M data blocks to be displayed, when N to-be-displayed parameters that do not meet the target display parameters are detected and acquired, the N to-be-displayed parameters are The preset target display parameters are adjusted, and the backlight sources corresponding to the N data blocks to be displayed are controlled to be displayed according to the N target display parameters. This enhances the screen display effects such as contrast, grayscale and color.

Abstract

The invention discloses a method for controlling a backlight source of a display device. The method comprises the following steps: performing display analysis on divided M data blocks to be displayed, and correspondingly obtaining M parameters to be displayed; from the M parameters to be displayed, Detect and obtain N parameters to be displayed that do not meet the target display parameters; control the backlight corresponding to the N data blocks to be displayed according to the N target display parameters; control the removal of N data blocks to be displayed from the M data blocks to be displayed The corresponding backlight is displayed according to the parameters to be displayed after display analysis, so as to realize the target backlight display in the area where the backlight is located in the area control display area. The invention also discloses a system for controlling the backlight source of the display device, which includes an acquisition unit, a division unit, an analysis unit and a control unit. By adopting the method and system of the present invention, the backlight display of the display device can be controlled and dynamically adjusted according to the content, thereby greatly enhancing the image display effect of the panel.

Description

Technical field [0001] The present invention relates to a technology for controlling a backlight source of a display device, in particular to a method and a system for dynamically controlling the backlight source of a display device. Background technique [0002] The current technology for controlling the backlight source of a display device is usually: a technology that uses a light emitting diode (LED, Light Emitting Diode) as a panel control panel backlight source. Currently, LED backlights have appeared in high-end notebooks and LCD TVs. The LED backlight is composed of many grid-shaped semiconductors, and each grid has an LED semiconductor, so that the LED backlight successfully realizes the planarization of the light source. The advantages of LED backlight technology are: ①It has high brightness, and can achieve stable brightness and color performance within the life span. ②It has a wider color gamut, which generally exceeds the color gamut of the National Television Syst...
