Embodiment Construction

[0021] The stereoscopic display device of the present invention will be described below with reference to the accompanying drawings.

[0022] see figure 1 , which is an exploded schematic view of a preferred embodiment of the stereoscopic display device of the present invention. The stereoscopic display device 1 includes a display 2 and a phase filter 3 , and the stereoscopic display effect can be observed through polarized glasses 4 in use. The polarizing glasses 4 include a left circular polarizer (not marked) and a right circular polarizer (not marked), which respectively analyze the information output by the phase filter 3, separate the images of the left and right eyes, and provide correspondingly to the left eye and right eye.

[0023] The display 2, such as a liquid crystal display 2, includes a plurality of sub-pixels.

[0024] The phase filter 3 is disposed between the display 2 and the polarizing glasses 4, and includes a TN-LCD 30 and a λ / 4 wave plate (not shown)...

Abstract

The invention provides a stereo display device. A user can watch the stereo display effect through polaroid glasses. The stereo display device comprises a display unit and a phase filter, wherein the phase filter is positioned between the display unit and the polaroid glasses; the phase filter comprises a TN-LCD; the TN-LCD comprises a first polarization region and a second polarization region which are adjacent to each other; linear polarized light passes through the first polarization region to generate a lambda/2 phase difference; the linear polarized light does not change a phase difference after passing through the second polarization region; and the juncture of the first polarization region and the second polarization comprises a shading region. The stereo display device has the advantages of low cost and favorable stereo display effect.

Description

technical field [0001] The invention relates to a stereoscopic display device, in particular to a stereoscopic display device using a TN-LCD (Twisted Nematic-LCD, Twisted Nematic-LCD) type phase filter. Background technique [0002] Now more and more stereoscopic display devices are used in many occasions. The basic principle of the stereoscopic display is to provide two different pictures for the left and right eyes of the person, and the brain synthesizes the two pictures into a three-dimensional effect. of the image. There are many ways to provide these two pictures separately, among which polarized glasses are used to detect the information output by a phase filter, so as to separate the left and right eye images and provide them to the left and right eyes respectively. [0003] At present, the phase filter in the stereoscopic display device generally adopts the optical film of the micro-polarizer array formed by laser etching, and the phase difference is realized by th...
