Embodiment Construction

[0019] Such as figure 1 Shown, a kind of liquid crystal display production line test result preservation method of the present invention, it comprises the following steps:

[0020] 1) When the burning program burns the extended display identification data (EDID), it sends the original serial number (SN) data to the LCD and saves it in the firmware of the LCD; specifically, at the station where the EDID is burned , you can use a code reading gun to read the code, and all or part of the serial number data is saved in the EDID, which meets the premise of the test program to read the original serial number data.

[0021] 2) calling the test program to test the liquid crystal display, the test program directly reads the original serial number data from the firmware of the liquid crystal display before the test, and generates the target serial number data based on the original serial number data;

[0022] 3) When the acquisition of the target serial number data fails, the test prog...

Abstract

The invention discloses a liquid crystal display device production line test result storage method. The method comprises the steps that: (1) when a burning program burns extended display identification data, original serial number data is sent to a liquid crystal display device and is stored into a firmware of the liquid crystal display device, (2) a test program is called to test the liquid crystal display device, the test program directly reads the original serial number data from the firmware of the liquid crystal display device before a test and generates target serial number data based on the original serial number data, (3) when the acquisition of the target serial number data is failed, the test program display an acquisition error and prompts an operator to carry out exception handling, (4) when the acquisition of the target serial number data is successful, the test program carries out test according to a selected test item, (5) the test program stores a test result and corresponding target serial number data into a local or network database after the test item is completed, and (6) the test program prompts a corresponding liquid crystal display device that the test is completed and notifies the operator to test a next liquid crystal display device. The method has the advantages of short testing and burning times, no need of manual reading of a code, the effective reduction of manpower, the improvement of efficiency and the reduction of production cost.

Description

technical field [0001] The invention relates to the technical field of liquid crystal production, in particular to a method for storing test results of a liquid crystal display production line. Background technique [0002] In the production of LCD monitors, in order to facilitate abnormal analysis, it is necessary to save the adjustment results and unique serial numbers of each monitor. Generally, ordinary code reading guns are used, and the barcodes required for manual alignment are read into the adjustment program. Manual code reading will take up manpower, and it is easy to read the wrong barcode. The reading time is about 3 seconds, and the efficiency is low. Using a high-precision code reading gun reduces the code error rate, but the cost of code reading equipment is high and the efficiency is also low. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method for storing test resul...
