Stereo display device

Abstract

An embodiment of the disclosed technology provides a three dimension display device comprising a polarized light modulator and a display unit comprising a lighting display array and a transparent substrate, wherein a lens array comprises multiple converging lenses is further provided between the lighting display array and the polarized light modulator, each left eye image pixel and each right eye image pixel in the lighting display array are respectively aligned with at least one of the converging lenses.

Description

technical field [0001] The invention relates to a stereoscopic display device, which belongs to the technical field of stereoscopic display. Background technique [0002] Such as figure 1 As shown, the existing stereoscopic display device includes a display unit 10 , a polarizer 20 and a polarization modulation device 30 . Wherein, a part of the pixels of the display unit 10 display the left-eye image (as shown in the left slanted line hatching among the figures), and another part of the pixels display the right-eye image (as shown in the right slashing line shading among the figures); After the light passes through the polarizer 20, it becomes polarized light with a single direction, such as figure 1 Among them, the polarization direction is polarized light parallel to the direction of the paper (shown as double parallel lines in the figure); the polarization modulation device 30 can specifically be a retardation plate or a liquid crystal cell ( figure 1 The polarization...

Problems solved by technology

[0004] like image 3 As shown, in fact, in addition to the light-emitting display array 11, the existing display unit 10 will also inevitably include a transparent substrate 12 with a certain thickness, and the transparent substrate 12 and the polarizer 20 arranged on it will make the polarization modulation device There is a certain distance between 30 and the light-emitting display array 11, which will cause crosstalk between left and right eye images, that is, the right eye of the viewer will also see the left eye image, and the left eye will also see the right eye image

[0005] For example, if Figure 4A As shown, when the viewer is facing the polarization modulation device 30, the light emitted by all the display pixels corresponds to the corresponding part of the polarization modulation device 30, so that the viewer can see the three-dimensional effect; as Figure 4B As shown, when the position of the viewer rises to , as shown by the dotted line, the polarized light of the left-eye image also passes through the part of the polarization modulation device 30 originally corresponding to the polarized light of the right-eye image, thereby being viewed by the viewer's Viewed by the right eye, thus creating crosstalk between left and right eye images
