Ageing testing system

Abstract

This invention is an ageing testing system, which is electrically connected with plane display panel and is used for ageing testing plane display panel. The system at least comprises a signal generator used to generate a power signal and first control signal; at least one signal adjusting circuit which is electrically connected with signal generator to turn first control signal into second control signal for outputting according to a testing condition; at least one boosted circuit which is electrically connected with signal adjusting circuit and used to boost power signal and second control signal level and driving ability and then by boosting voltage to realize the power signal driven plane display panel and second control signal and take ageing testing of plane display panel.

Description

technical field [0001] The invention relates to a detection system, in particular to an aging detection system. Background technique [0002] In recent years, due to the improvement of consumers' consumption awareness, the quality requirements of products have become more and more stringent. Manufacturers of LCD panels must not only work hard on product design, but also improve their manufacturing processes in order to compete in such a competitive market. The last battle is long and short. For liquid crystal display panel manufacturers, the product life cycle has always been the focus of the industry, and the burn-in test provides manufacturers with one of the ways to certify the manufacturing process and improve product reliability. The products after the aging test can not only ensure the reliability and life cycle of the products, but also make the products out of the factory not easy to fail. [0003] Since LCD panels are prone to failure after an indeterminate period...

Problems solved by technology

[0006] However, due to the current information appliance (IA) system structure is very messy, there is no standard regulation, and there are many signal source specifications, most of the designs are only used for medium-sized and above LCD panels, and small-sized low-temperature LCD panels cannot be purchased on the market. The signal source specification used by the polysilicon thin film transistor liquid crystal module requires the industry to develop and design a field programmable gate array (FPGA) chip to meet the signal source and driving voltage required by the small size low temperature polysilicon thin film transistor liquid crystal module

In addition, currently used single Field Programmable Gate Array chip (FPGA) can only drive a single flat display panel due to insufficient driving capability of the signal source, and cannot drive many panels at the same time. Field Programmable Gate Array chip (FPGA) The price of FPGA) is not cheap, which also makes the cost of setting up the burn-in test system much higher, and because of insufficient driving capacity, the production capacity cannot be increased
