Abstract

The invention discloses a method and device for automatically detecting a 4K2K product main control board. The method comprises the steps that a V-BY-ONE collection and conversion device collects a V-BY-ONE signal of the 4K2K main control board to be detected, coverts the signal into an RGB image signal, and transmits the RGB image signal to a central processing module, the automatic detection and the judgment of the image signal of the 4K2K main control board to be detected are completed, a voice collection and conversion device collects a board card voice signal of the 4K2K main control board to be detected, and the detection and the judgment of the board card voice signal are completed; a voltage and current collection and conversion device collects board card voltage and current signals of the 4K2K main control board to be detected, so that the detection and the judgment of the board card voltage and current are completed; the central processing module outputs the final judgment result to a test result output module, and the detection process is in the full-automatic detection. The method and device achieve full-automatic detection on the main control board to be detected, and is high in detection efficiency, high in accuracy rate, and stable and reliable in detection result.

Description

technical field [0001] The invention relates to the technical field of detection equipment for product main control boards, in particular to a method and device for automatically detecting a 4K2K product main control board. Background technique [0002] As users continue to improve the quality of multimedia display products, TVs with super large screens and ultra-high definition are getting closer and closer to our lives. Such as Sony, Toshiba, LG, Samsung, Hisense, Haier, Skyworth, TCL, Konka, Changhong and other major TV manufacturers at home and abroad have launched various models of ultra-high-definition TVs with 4K2K interfaces this year, as well as major LCD panel manufacturers For example, Innolux, AUO, Samsung, and Sharp have launched 4K2K LCD panels of different sizes, which are used in various multimedia display products. Ultra-high-definition 4K2K multimedia display products use the new data transmission method of V-BY-ONE to complete large data At present, it se...
