Description

TECHNICAL FIELD

[0001] The present application relates to the field of display module, in particular to a LCD testing device. BACKGROUND

[0002] In the production process of liquid crystal display module, the bending resistance of the liquid crystal display glass (LCD) needs to be tested. During the test, two cylindrical pressure rods (8mm in diameter) are used to press the center line of the liquid crystal display glass placed on two supports (8mm in diameter) at a speed of 10mm / min until the sample is damaged. During the test, the operator usually needs to manually place the liquid crystal display glass on the two supports and then control the pressure rod to press down for testing. To ensure the accuracy and reliability of the test results, the center line of the product to be tested should be perpendicular to the length direction of the pressure rod before testing, and the two pressure rods and the two supporting rods should also be symmetric to the other center line of the product to be tested. The current method for observing whether the center line of the product to be tested is perpendicular to the length direction of the pressure rod is mainly by comparing the positioning line on the sample to be tested with the center observation line on the equipment through the naked eye; the method for observing whether the two pressure rods and the two supporting rods are symmetric to the center line of the product to be tested is mainly by observing the distance from the two pressure rods and the two supporting rods to the center line through the naked eye, which needs full manual operation (manual loading, naked eye observation, and manual pressing down), and has the problems of high testing cost and inaccurate testing.
