Problems solved by technology

Once the alignment deviation occurs, there will be crosstalk between the first image and the second image, which will affect the display quality
However, the existing polarization modulation device 30 is almost transparent, so it is difficult to achieve precise alignment with the display unit 10

Abstract

The invention provides a method and equipment for calibrating a display device. The method comprises the following steps of: in a display unit, displaying a first color by a pixel corresponding to a first image, and displaying a second color by a pixel corresponding to a second image; polarizing and filtering the first color and the second color by a polarizer to form initial polarized light; performing polarization modulation on the initial polarized light by a polarization modulation device to emit first polarized light and second polarized light, wherein the polarization direction of the first polarized light is orthogonal with the polarization direction of the second polarized light; monitoring the first polarized light and the second polarized light by a polaroid; and adjusting relative positions of the polarization modulation device and the display unit until the colors monitored by the polaroid are the first color. By the method and the equipment, the polarization modulation device and the display unit in the display device can be aligned with each other precisely; and the method and the equipment are simple and easy, and are high in precision.

Description

technical field [0001] The invention relates to a display device calibration method and calibration equipment, belonging to the technical field of stereoscopic display and double-view display. Background technique [0002] Stereoscopic display technology is a technology that enables the left and right eyes of the same viewer to observe different images respectively, thereby generating a stereoscopic effect. Dual-view display technology is a technology that enables different viewers to see different images on the same display device. The implementation principles of these two technologies are relatively similar, and both use display devices capable of playing different images and equipped with polarized glasses. The difference is that the left and right lenses of the polarized glasses used in the stereoscopic display technology have different polarizations. Direction, so that the left and right eyes of the same viewer observe different images to produce a three-dimensional e...
