Abstract

The invention discloses an error detection method and a lighting fixture, which are used for a lighting detection application program of a liquid crystal screen, wherein the error detection method includes: when the lighting detection application program is executed for the first time, calculating the lighting detection The error detection index of the application program, and store the error detection index in the non-volatile memory where the lighting detection application program is located. The error detection index includes: standard cyclic redundancy check code, error check and correction code and indicator code; According to the indicator code, when the lighting detection application program is not executed for the first time, use the standard cyclic redundancy check code to perform error detection on the lighting detection application program, and judge whether the lighting detection application program can be corrected; where correctable, the error codes of the lighting detection application are corrected using error checking and correction codes. The error detection method disclosed by the invention solves the variation problem of the lighting detection program stored in the non-volatile memory during the liquid crystal screen lighting detection process.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, and more specifically, to an error detection method and a lighting fixture. Background technique [0002] Liquid crystal display devices have the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation, and relatively low manufacturing costs, and currently occupy a dominant position in the field of flat panel displays. [0003] After the liquid crystal screen of the liquid crystal display device completes various production processes, it is necessary to light up and detect whether there is a defect in the liquid crystal screen. The programmable device in the lighting fixture can be used to light up the LCD screen, but the clock and resolution of the LCD screen with different parameters are different, which requires programmable devices configured with different lighting detection programs to light up the correspon...
