Embodiment Construction

[0016] figure 2 Application of the method of the present invention display monitor 20. Display 20 comprises a display panel 22 and a backlight 24. The display panel 22 for displaying images. The backlight panel 24 is located below the display panel 22 and having a plurality of light emitting regions 242, each light emitting region 242 comprises one or more light emitting elements (not shown), such as light emitting diodes. A brightness of each light emitting region 242 can be independently controlled, so that the luminance of the plurality of light-emitting regions 242 may be different. image 3 Display 30 for displaying the image display 20, image 30 may be divided into a plurality of sub-regions 32 corresponding to the plurality of light emitting regions 242, respectively, each sub-region 32 comprises a plurality of pixels.

Abstract

A method for improving halation effect of a display is provided, the display is used for displaying an image and comprises a backlight plate, the image comprises a plurality of sub-regions, and the backlight plate is provided with a plurality of light-emitting regions respectively corresponding to the plurality of sub-regions. The method comprises the following steps of: determining brightness information of each sub-region; selecting one sub-region as a target region, and determining a correction value according to the maximum value of the brightness information of other sub-regions adjacent to the target region; and adjusting the brightness of the light-emitting area corresponding to the target area according to the correction value.

Description

Technical field [0001] The present invention relates to a method for improved display halo effect. Background technique [0002] A display system having a local dimming (local dimming system) is displayed in a dark scene image (dark-scene image), the light leakage generated by a halo effect (halo effect) may occur in the black pixel. Please refer to figure 1 , figure 1 A plurality of light emitting regions of the backlight sub-Videos dotted line. like figure 1 , When the display shows a dark scene image 10, if a large area of ​​the bright region 12 occurs, a halo effect imperceptible to the human eye. However, when a dark scene image 10 appears in a small area of ​​the bright region 14, the human eye will see the edge of the bright area 14 of halos. Especially in a dark environment, the halo effect will be more obvious. Traditional method of suppressing a halo effect is the overall luminance of the backlight is lowered. However, while a large area of ​​the bright region 12 and a ...
