Embodiment Construction

[0047] figure 1 It is a schematic diagram of viewing glasses for a 3D display device according to an embodiment of the present invention. Please refer to figure 1 , wherein the viewing glasses 100 are used to view images displayed on a display screen 106 by the three-dimensional display device. The 3D display device here is, for example, a linearly polarized 3D liquid crystal display, a 3D projector and other stereoscopic image display devices, or any display or projector that can emit linearly polarized light. When the three-dimensional display device is a three-dimensional liquid crystal display, the display screen 106 means the picture area displayed by the liquid crystal display panel on the three-dimensional liquid crystal display, and when the three-dimensional display device is a three-dimensional projector, the display screen 106 means the area projected by the three-dimensional projector The area on the plane where the screen is displayed.

Abstract

The invention relates to an image light beam adjusting method for a pair of a pair of viewing glasses. The pair of viewing glasses comprises polaroids. The image light beam adjusting method comprises the following steps: measuring the penetration rate of an image light beam after passing through the viewing glasses, wherein the image light beam is from a display screen; generating an operation signal according to a period of the viewing glasses, a corresponding value corresponding to the period of the viewing glasses and the penetration rate of the image light beam, thereby adjusting the polarizing direction of the image light beam before passing through the polaroids and causing the penetration rate to be equal to the corresponding value corresponding to the period of the viewing glasses, wherein the period of the viewing glasses is a non-viewing period or a viewing period; and maintaining the operation signal during the period of the viewing glasses.

Description

technical field [0001] The present invention relates to an image beam adjustment method, and in particular to an image beam adjustment method using viewing glasses. Background technique [0002] With the advancement of science and technology, in the development of display technology, in addition to pursuing the lightness, thinness and compactness of the display device, it is more hoped to achieve the goal of displaying three-dimensional images. Generally speaking, the principle of displaying a three-dimensional image is to send two different images to the left and right eyes respectively, so that the brain constructs a three-dimensional (3D) image. [0003] At present, 3D display technology can be mainly divided into two types, that is, a display technology that requires wearing glasses and a display technology that does not require wearing glasses. The part that wears glasses can be divided into early red and blue glasses, shutter glasses, and today's polarized glasses. N...
