Touch screen test system and touch screen test method

Abstract

The invention belongs to the technical field of display and particularly relates to a touch screen test system and a touch screen test method. The touch screen test system comprises a signal provision unit, a signal integration unit, a static electricity applying unit and a test unit, the signal provision unit is used for providing the single touch screen with required power supply voltage and a driving signal in a working condition; the signal integration unit is used for converting the power supply voltage and the driving signal of the signal provision unit and the converted power supply voltage and the driving signal are applied to the single touch screen; the static electricity applying unit is used for providing the single touch screen with a static electricity trigger signal; the test unit for analyzing the static electricity discharge condition of the single touch screen according to the analysis of the test signal receives the test signal of the single touch screen. According to the touch screen test system and the touch screen test method, an anti-ESD performance test basically in sync with production and for the touch screen in the work condition can be achieved, and the current touch screen product performance is learnt timely.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a touch screen testing system and a touch screen testing method. Background technique [0002] The touch screen (Touch Panel, TP for short) can provide users with a brand-new control experience, and it has now become a widely used external input device, and its use environment is becoming more and more diverse. Electro Static Discharge (electrostatic discharge) capability also puts forward strict requirements. [0003] Usually, the anti-ESD test of the manufacturer after the touch screen product is produced, because it has not been assembled with the display substrate to form a complete product, it is impossible to provide the test status of the touch screen under normal working conditions. At this time, the anti-ESD The test can only reflect the anti-ESD ability of a single touch screen, and cannot obtain the anti-ESD ability of the whole machine (which can be any ...

Problems solved by technology

[0003] Usually, the anti-ESD test of the manufacturer after the touch screen product is produced, because it has not been assembled with the display substrate to form a complete product, it is impossible to provide the test status of the touch screen under normal working conditions. At this time, the anti-ESD The test can only reflect the anti-ESD ability of a single touch screen, and cannot obtain the anti-ESD ability of the whole machine (which can be any terminal product with a touch screen) after the touch screen is combined with the display substrate; and invite customers of downstream display panel manufacturers to test the whole machine The test has a long cycle, and it is impossible to know the performance of the current touch screen product in time, and it is difficult to give feedback on the touch screen production line and design in time and make timely adjustments
