Device and method for achieving double display screen 3D display by adoption of serial processing mode

Abstract

The invention discloses a device and method for achieving double display screen 3D display by the adoption of a serial processing mode. The device comprises an image segmentation unit, a left eye image buffering unit, a right eye image buffering unit, a first channel switching unit, an image processing unit, a second channel switching unit, a left eye image driving buffering unit, a right eye image driving buffering unit, a left display unit, a right display unit and a control unit. The serial processing mode that gating input is performed on a left eye image signal and a right eye image signal after segmentation and image processing is performed on the input image signals is adopted, and the processing speed of the serial processing mode is comparative to that of a mode that in the prior art, parallel image processing is performed on 3D image signals. However, regarding the achieving of the method, the method for the 3D display is easier to achieve, and configuration cost is also lower.

Description

technical field [0001] The invention belongs to the field of display technology, and relates to a 3D display device and a method thereof, in particular to a design of a device and a method for realizing dual-screen 3D display by adopting a serial processing method. Background technique [0002] With the development and transformation of science and technology, the field of display technology has also transitioned from CRT display to the era of LCD and LED display, and people have gradually begun to put forward requirements for 3D stereoscopic display technology from watching 2D video images. The so-called 3D display technology is the use of A series of optical methods make people's left and right eyes produce parallax to receive different pictures, forming a 3D stereoscopic display effect in the human brain. The 3D display devices and methods in the prior art mainly include two categories: the first type is a 3D display device that uses a single display to display binocular ...

Problems solved by technology

However, using the space allocation method will reduce the horizontal resolution of the image by half, and its display brightness will also drop by half immediately, and the linearly polarized 3D glasses select the light through the polarizing film, so the user's wearing angle will have a certain impact on the display effect. Influenced by the same reason as the polarizing film, the display brightness will further decrease

[0003] The second category is a 3D display device that asynchronously displays binocular 3D image signals through the time-division method. Type 3D glasses use TN liquid crystal to switch between shading and light transmission, so its light transmittance is low, only 35%, and the color temperature of the picture will shift to a certain extent, which will have a certain impact on the display effect viewed by users

The second item is to display 3D image signals through dual displays, such as figure 1 Shown is a structural block diagram of a 3D display device with dual display screens in the prior art. Users can watch its 3D display effect without wearing 3D glasses, which avoids display defects caused by wearing 3D glasses. It uses parallel dual GPU image processing The unit processes 3D images, but the existing problem is that the 3D display device with dual GPUs has a complex system structure, low reliability, high power consumption and high heat generation of the system, and high cost of the device
