Backlight module, display device and use method of backlight module

Abstract

The embodiment of the invention provides a backlight module, a display device and a use method of the backlight module and relates to the field of liquid crystal display. The backlight module can reduce view crosstalk of the left eye and the right eye and improve the 3D watching effect. The backlight module comprises a back panel and a diffusion plate. At least one LED lamp strip is arranged on the back plane. The backlight module further comprises at least one reflecting sheet and a control unit. The reflecting sheet is located between a backlight source and the diffusion plate. The control unit is used for controlling opening of the reflecting sheet corresponding to the first LED lamp strip when the first LED lamp strip is turned on. The backlight module and the display device are applied to the liquid crystal display field.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module, a display device and a use method thereof. Background technique [0002] With the rapid development of technology, the TV industry has also experienced technological progress from black and white to color, high definition to 3D (Three Dimensions, three-dimensional), and now people can already enjoy the immersive three-dimensional sense brought by 3D TV. The display principle of 3D TV is to make the images seen by the left and right eyes of the viewer different. In the process of watching, you will see a three-dimensional image. [0003] The currently used 3D liquid crystal display technology adopts progressive backlight scanning technology, that is, the backlight includes at least one LED (Light Emitting Diode, light-emitting diode) light strip, and the at least one LED light strip lights up row by row, and the 3D liquid crystal display The technology divid...

However, after one line of image display on the LCD panel is completed, the next LED light bar is lit to display the next line of image. At this time, the image data displayed in this line is still retained. It will illuminate the LCD panel of the next row, and part of the light will also be scattered to the LCD panel of this row, so that the retained image data will continue to be displayed, forming crosstalk

Since the images of the left and right fields of view of the 3D signal are continuously interlaced, the images of the left eye and the right eye are displayed respectively in two adjacent scans, so the viewer can also see the image of the right eye while seeing the left eye image, or Seeing the image for the right eye while seeing the image for the left eye will cause crosstalk between the left and right eye views and affect the 3D viewing effect
