Embodiment 1
[0080] In this embodiment, a liquid crystal display screen with a resolution of 1920*1080 is taken as an example for illustration.
[0081] Such as figure 1 As shown, the image display method of the liquid crystal display in this embodiment divides the liquid crystal display into A, B, C, D, E, F in the vertical direction, 6 display areas, based on the division method of the image display area, this implementation In the example, the backlights are set on the left and right sides of the LCD screen, and the backlights on the left and right sides are also divided into 6 groups of backlights corresponding to a, b, c, d, e, and f respectively corresponding to the 6 display areas. .
[0082] Such as image 3 As shown, the image display method of the liquid crystal display in this embodiment is illustrated by taking two frames of images continuously input on the liquid crystal display as an example. In this embodiment, the liquid crystal display inputs an image in RGB format, and ...
Embodiment 2
[0155] In this embodiment, a liquid crystal display screen with a resolution of 1920*1080 is taken as an example for illustration.
[0156] Such as figure 2 As shown, in the image display method of the liquid crystal display in this embodiment, the liquid crystal display is divided into G, H, I, J, K, L, M, N in the horizontal direction, 8 display areas, based on the division of the image display area way, in this embodiment, the backlights are arranged on the left and right sides of the liquid crystal display, and the backlights on the upper and lower sides are also divided into g, h, i, j, k, and l corresponding to 8 display areas respectively, 8 groups of backlights.
[0157] The image display method of the liquid crystal display in this embodiment is illustrated by taking two frames of images continuously input on the liquid crystal display as an example. In this embodiment, the liquid crystal display inputs images in RGB format, and the first frame of image data is divi...

Abstract
The invention discloses a liquid crystal display screen image displaying method, a device and a liquid crystal display television and aims to provide a liquid crystal display screen image displaying method with backlight value which can be rapidly switched based on changes of image scenes without flickering. According to the liquid crystal display screen image displaying method, a liquid crystal display screen is transversely or longitudinally divided into at least two display areas, adjustment backlight values of the display areas are respectively determined according to maximum brightness of image pixels in the display areas and whether scene change of the image does occur or not, the image compensation coefficient of the image of each display area is calculated based on the adjustment backlight values, the image compensation is performed for the image of a current frame according to the image compensation coefficient, and each image display area on the liquid crystal display screen respectively outputs compensated image and the adjustment backlight values for image displaying. The liquid crystal display screen image displaying method, the device and the liquid crystal display television have the advantages that the liquid crystal display screen image displaying method is suitable for edge-lit liquid crystal display screens, light-emitting diodes (LEDs) are reduced, the screen power consumption is lowered, the screen contrast ratio is improved, and the light leakage in dark field is eliminated.
Description
technical field [0001] The invention relates to the field of image display of liquid crystal display screens, in particular to a method and device for displaying images of liquid crystal display screens and a liquid crystal television using the method and device. Background technique [0002] In the liquid crystal display, by adjusting the brightness of the backlight, the energy consumed by the backlight is saved, and the contrast of the picture is improved at the same time, and the light leakage of the screen is improved. At present, there are two main methods of backlight adjustment, one is global dimming (Global Dimming), which adjusts the brightness of the entire backlight at the same time to achieve the purpose of reducing the power consumption of the backlight; the other is local dimming (Local Dimming). Dimming), by separately adjusting the brightness of the backlight source corresponding to each display area of the LCD screen, to achieve the purpose of reducing pow...
