Full automatic adjustment and test system for liquid crystal display

Abstract

The invention relates to a full automatic adjustment and test system for a liquid crystal display, comprising an industry control PC, a safety test system connected to the industry control PC, a powertester, a signal generator and a burning control card, wherein the safety test system, the power tester, the signal generator and the programming control card are respectively connected to the liquidcrystal display to be tested, and the system adopts the industry control PC as the core thereof, controls the safety test system, the power tester and the signal generator needed by the test by the serial port communication of the industry control PC, and realizes the functions of automatic color gradation and language selection, HDCP burning, DDC burning, DDC detection, and the like by the parallel port communication of the industry control PC and the burning control card. The system has the advantages that full automatic test and burning can be carried out during the production of the liquid crystal display, and the production efficiency and the product quality are improved.

Description

【Technical field】 [0001] The present invention relates to a test system, in particular to a fully automatic adjustment test system suitable for liquid crystal displays. The system takes an industrial PC as the core and integrates safety test modules, power test modules, burning modules and The signal generator control module is integrated. 【Background technique】 [0002] The current operation methods of the LCD production line include power test, high voltage test and grounding test, automatic color level (Auto level) and language selection (Select Language), HDCP (High Bandwidth Digital Content Protection) burning, DDC (Display Data Channel) ) programming and DDC inspection and other pipeline operations. [0003] The power test refers to testing whether the energy consumption of the monitor in normal operation and energy-saving mode is qualified according to Energy Star or other standards. In the production of LCD monitors and LCD TVs, the power test is divided into two p...

AI Technical Summary

Problems solved by technology

[0011] 1. During the test, due to the assembly line operation method, each station needs to plug and unplug the power line and signal line, repeating the action, wasting time;

[0012] 2. During the whole test process, the waiting time of the operator is divided into two parts: waiting for the display to flow to the predetermined station and waiting for the display status of the response, which leads to the inability to perform other operations during this waiting time and reduces efficiency;

[0013] 3. The existing technology is judged by manual operation, and there are hidden dangers of personnel operation loss;

[0014] 4. For the safety test part, the manual operation process is the same as the need to plug and unplug the high-risk test line, which has potential safety hazards for personnel;

[0015] 5. Due to the need for repeated wire insertion and the vibration of the collector plate, it may lead to poor contact and serious wire consumption
