Naked-eye stereoscopic display system and method for realizing naked-eye stereoscopic display

Abstract

The invention discloses a naked-eye stereoscopic display system with a low crosstalk rate. The system comprises an LED (Light-Emitting Diode ) backlight module, a display screen and a comprehensive processor, wherein the LED backlight module comprises an LED left eye sub-element and an LED right eye sub-element; the display screen comprises an LCD (Liquid Crystal Display) screen and an optical screen; the comprehensive processor receives a stereoscopic image signal, then controls the brightening and vanishing of the LED left eye sub-element and the LED right eye sub-element by transmitting an LED brightening and vanishing signal and an LCD refresh signal to an LED driver and an LCD driver respectively, and drives the LCD screen to be refreshed synchronously, so that only a left eye image is refreshed on the LCD screen within the time that the LED left eye sub-element is opened, and only a right eye image is refreshed within the time that the LED right eye sub-element is opened. According to the system, the left and right crosstalk of images is avoided; and the crosstalk rate is reduced greatly.

Description

technical field [0001] The invention relates to a stereoscopic display system, in particular to a display system used for naked-eye stereoscopic display technology. Background technique [0002] Stereoscopic display technology has become an important part of the display industry. Stereoscopic display technology has been developed rapidly. Various stereoscopic display technologies have become commercial products. Stereoscopic TV channels are also being popularized in the world. Stereoscopic display technology has become an inevitable development direction in the future display field. [0003] The current stereoscopic display technology is mainly divided into two types, which are assistive and autostereoscopic display. Assisted stereoscopic display technology requires viewers to wear special devices to see stereoscopic images. Head-mounted display (HMD) and glasses are two mainstream technologies of assisted stereoscopic display technology. The helmet-mounted technology re...

Problems solved by technology

Compared with the visual barrier grating method, the brightness of this method is greatly improved, but the pixels will be compressed, and the source of multi-viewpoint is not compatible with the source of the existing stereoscopic display, and the manufacturing process of the large-area lens is difficult and the cost is high. failed to promote widely

[0007] The integrated imaging method can easily overcome the shortcomings of the current self-owned stereoscopic display technology, but because it is difficult to collect images, and it is difficult to manufacture large-area microlens arrays, integrated imaging is still at the stage of scientific research.
