Three-dimensional image display device

Abstract

The invention provides a three-dimensional image display device which comprises a polarization module, a non-vertically-arranged polarization light shielding grating unit and an image display unit. The polarization module outputs polarized light. The non-vertically-arranged polarization light shielding grating unit is arranged in a light path of the polarized light, so as to modulate the polarized light, thereby respectively outputting modulated polarized light in an interlacing manner. The image display unit receives the modulated polarized light of the non-vertically-arranged polarization light shielding grating unit, so as to output two or more images with parallax errors.

Description

technical field [0001] The present invention relates to an image display technology, and in particular to a stereoscopic image display technology. Background technique [0002] In the traditional 3D image display technology, the 3D image display uses a mask (barrier) mechanism, and the types of barriers can be divided into three types, namely, energy masks, polarization masks and color masks. In the past, the mask-type stereoscopic display device mainly used the energy mask method, and its structure is as follows: figure 1 shown. figure 1 A schematic diagram showing a conventional mechanism for displaying stereoscopic images using an energy blocking layer. refer to figure 1 , a backlight panel 100 provides a light source and illuminates the parallax barrier (Parallax Barrier) 101. The parallax barrier 101 has vertical stripes alternated between light-transmitting and opaque, so that the light emerges in the form of spaced strips, and then cooperates with the transmissive ...

Problems solved by technology

refer to figure 2 , whose structure is the same as figure 1 Vertical stripes are also used, the difference is that the positions of the parallax mask 101 and the transmissive display unit 102 are exchanged, in other words, figure 1 The transmissive display unit 102 is arranged on the same side of the backlight plate 100 and the parallax mask 101, figure 2 Then the transmissive display unit 102 is arranged between the backlight plate 100 and the parallax mask 101, figure 2 The effect obtained is as figure 1 As shown, the resolution in the X direction is also reduced by half, the 2D / 3D display mode cannot be switched, and the orientation of the screen is limited, only a parallax mask with vertical stripes
