Stereoscopic display

Abstract

The invention discloses a stereoscopic display which comprises a display panel, a controller for glasses, an image controller and a backlight controller, wherein the display panel is divided into N blocks; the controller for the glasses is used to control open and close of a left glass and a right glass; the image controller is used to generate an image data enable signal; the backlight controller is used to control open and close of each block backlight; the display panel receives a left eye image signal, a right eye image signal, a left eye backlight signal and a right eye backlight signal and displays a left eye picture or a right eye picture based on these signals. In the invention, a region type backlight is adopted, the synchronization of backlight and liquid crystal display scanning is utilized and the problem of left and right images interference (Corsstalk) of the stereoscopic display is solved without increasing circuit cost; as the backlight of the display disclosed by the invention can be lightened when opening the glasses (the left glass or right glass), therefore, the service efficiency of the backlight is higher than that of the traditional on-and-off glass type stereoscopic display with a constant light of backlight and the power consumption can be saved.

Description

technical field [0001] The invention belongs to the technical field of displays, in particular to a stereoscopic display. Background technique [0002] Three-dimensional display technology can be divided into spatial type and time type according to the display method. The former displays the images of the left and right eyes at the same time, and uses different methods to separate the images that can be seen by the left and right eyes, while the latter sends the images of the left and right eyes at different times. Eye image, the disadvantage of the former is that the resolution of the display is reduced and the way of isolating the left and right eyes is not good, which will easily cause the images of the left and right eyes to interfere with each other (called Crosstalk). The power consumed by the backlight is ineffective; and because the liquid crystal display adopts a vertical scanning method, the liquid crystal response cannot be synchronized with the glasses, resulting...

[0002] Three-dimensional display technology can be divided into spatial type and time type according to the display method. The former displays the images of the left and right eyes at the same time, and uses different methods to separate the images that can be seen by the left and right eyes, while the latter sends the images of the left and right eyes at different times. Eye image, the disadvantage of the former is that the resolution of the display is reduced and the way of isolating the left and right eyes is not good, which will easily cause the images of the left and right eyes to interfere with each other (called Crosstalk). The power consumed by the backlight is ineffective; and because the liquid crystal display adopts a vertical scanning method, the liquid crystal response cannot be synchronized with the glasses, causing interference between the left and right eye images (Crosstalk)

The traditional three-dimensional display technology of switching glasses is a time-based three-dimensional display technology. When the screen is displayed, the backlight is continuously lit, and the image data of the LCD monitor is updated by scanning from top to bottom. When the image data update is completed, the unilateral glasses are turned on. The left eye can see the image for the left eye, and the right eye can see the image for the right eye, but because the liquid crystal needs time to react, the bottom of the panel has not yet responded to the proper image, resulting in one eye seeing the images of the left and right eyes at the same time
