Error detection method and lightening fixture

Abstract

The invention discloses an error detection method and a lightening fixture, which are used for a lightening detection application program of a liquid crystal screen. The error detection method comprises the following steps: when the lightening detection application program is executed for the first time, calculating error detection indexes of the lightening detection application program, and storing the error detection index into a nonvolatile memory where the lightening detection application program is located, wherein the error detection indexes comprise a standard cyclic redundancy check code, an error check and correction code and an indication code; according to the indication code, when the lightening detection application program is not executed for the first time, error detection is conducted on the lightening detection application program through the standard cyclic redundancy check code, and whether the lightening detection application program can be corrected or not is judged according to the error detection and correction code; and under a correctable condition, the error code of the lightening the detection application program is corrected by utilizing the error checkand correction code. According to the error detection method disclosed by the invention, the variation problem of the lightening detection program stored in the nonvolatile memory in the lightening detection process of the liquid crystal screen is solved.

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...
