Abstract

The invention discloses an optical performance detection device of a liquid crystal projector. The optical performance detection device of the liquid crystal projector comprises a debugging control computer, a digital signal generator, a color difference meter, a luminance meter, an alternating-current voltage stabilization power source and a projector to be detected. Four control ports of the debugging control computer are connected to the digital signal generator, the projector to be detected, the color difference meter and the luminance meter respectively through serial communication lines. The projector to be detected is connected to the alternating-current voltage stabilization power source. The projector to be detected is further connected with the digital signal generator. Seventeen test sensors are installed on a projection screen of the projector to be detected. The optical performance detection device of the liquid crystal projector is arranged in a test darkroom. According to the optical performance detection device of the liquid crystal projector, the projector is automatically detected through an optical automatic detection PC, detection work is simplified, detection time is reduced, the number of detection inspectors is reduced, detection efficiency is improved, detection missing and false detection by the detection inspectors are avoided, and automatic storage of detected data can be further achieved.

Description

【Technical field】 [0001] The invention belongs to the field of projector manufacturing, and in particular relates to an optical performance detection device in the production process of a liquid crystal projector. 【Background technique】 [0002] With the development of science and technology, various new electronic devices are applied to production and life. As a large-scale display output device, LCD projectors are widely used in teaching, conferences, and home theaters. LCD projectors must be inspected for optical performance during the production process, but the optical performance inspection process of conventional production lines relies on manual operation and manual judgment, which requires more workers, and there are often missed inspections and misjudgments, and the inspection efficiency is low . 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide an optical performance detection device in the production pro...
