Polarizer detection method for polarized three-dimensional (3D) liquid crystal television

Abstract

The invention is applied in the technical field of televisions, and provides a polarizer detection method for a polarized three-dimensional (3D) liquid crystal television. The method comprises the following steps that: a static two-dimensional (2D) test image is played in a peer-to-peer way on the polarized 3D liquid crystal television, wherein odd and even pixel lines of the test image can form static and distinguishable images respectively, and the images formed by the odd and even pixel lines are remarkably differentiated; and a detector wearing 3D polarized eyeglasses observes the picture of the television independently by a left eye and a right eye, determines that a polarizer is normal if the pictures observed by the two eyes are consistent with the images formed by the odd and even pixel lines, otherwise determines that the polarizer is abnormal. By the method, the detection efficiency of the polarizer can be remarkably improved, the reliability of a detection result can be improved, and the visual fatigue of the detector can be effectively alleviated.

Description

technical field [0001] The invention belongs to the technical field of televisions, and in particular relates to a polarizing film detection method of a polarized 3D liquid crystal television. Background technique [0002] Polarized 3D LCD TVs use a polarized screen to display content, and the polarized screen is composed of a polarized film attached to the front of an ordinary LCD panel. The polarizing film itself is relatively fragile, and requires high precision in the film attachment process, resulting in a high defect rate of the polarizing screen. In the product line of polarized 3D LCD TV sets, the polarizing film of the polarizing screen must be tested to ensure the 3D display effect. [0003] At present, the commonly used polarizing film detection method is: use the polarized 3D LCD TV to be tested to play 3D video, the inspector wears polarized glasses, and judges whether the polarizing film is normal by observing the display effect of the 3D image moving picture....
