Problems solved by technology

[0003] However, when the TFT-LCD drives a specific still picture for a long time, the ions in the TFT-LCD display panel will move to the upper and lower substrates of the liquid crystal along the direction of the electric field, and gather on the liquid crystal alignment layer, and the gathered ions will generate an internal electric field. When the display displays the next picture, the ions gathered in the alignment layer cannot leave the alignment layer, resulting in a residual DC voltage on the liquid crystal molecules, which makes the liquid crystal polarized so that it is difficult to change at a certain rotation angle
In this way, there will be differences when the TFT-LCD displays images. For example, when the display screen is switched to the next screen, the image of the previous screen will remain on the display panel, resulting in afterimages.
Afterimages will seriously affect the picture quality of the monitor

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] An embodiment of the present invention provides an image display control method, such as figure 1 As shown, can include:

[0028] S101. Receive at least one frame of image displayed on a display.

[0029] S102. When the display continuously displays the number of frames of the first image greater than or equal to the preset frame number T, control the display to display a frame of the second image interpolated.

[0030] Wherein, the first image is dif...

Abstract

Embodiments of the present invention provide an image display control method and device, which relate to the field of display technology and prevent liquid crystal displays from displaying static images for a long time, thereby eliminating afterimages. The image display control method includes: receiving at least one frame of image displayed on the display; and controlling the display to interpolate and display a frame of the second image when the number of frames continuously displayed by the display is greater than or equal to the preset number of frames. Wherein, the first image is different from the second image.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an image display control method and device. Background technique [0002] TFT-LCD (ThinFilmTransistorLiquidCrystalDisplay, Thin Film Transistor Liquid Crystal Display), as a flat panel display device, is more and more used in high performance display field. [0003] However, when the TFT-LCD drives a specific still picture for a long time, the ions in the TFT-LCD display panel will move to the upper and lower substrates of the liquid crystal along the direction of the electric field, and gather on the liquid crystal alignment layer, and the gathered ions will generate an internal electric field. When the display displays the next picture, the ions gathered in the alignment layer cannot leave the alignment layer, resulting in a residual DC voltage on the liquid crystal molecules, which makes the liquid crystal polarized so that it is difficult to change at a certain rota...
