Problems solved by technology
[0003] The current test device is not compatible with designs of different lengths L and width B, different bending radii R and different straight line segments l, resulting in problems of high cost and serious waste
However, the current test device adopts the approximate method of three-point bending to obtain the bending radius R, but the bending radius R does not match the actual situation, and the accuracy is not enough
In addition, the current test device cannot realize the measurement of the geometric dimensions of the curved liquid crystal display panel after forming
In addition, when testing the life of a curved liquid crystal panel, due to the long time required for fragmentation, existing products cannot monitor the destruction time

Description
【Technical field】 [0001] The disclosure relates to the field of display technology, in particular to an adjustable curved liquid crystal display panel test device and an operation method thereof. 【Background technique】 [0002] When the traditional display product market is weak, curved surface products are one of the key technologies to improve product competitiveness. Compared with flat display products, curved screens suffer from a forming stress on the glass due to the bending of the liquid crystal display panel. [0003] The current test device is not compatible with designs of different lengths L and width B, different bending radii R and different straight line segments l, resulting in problems of high cost and serious waste. However, the current test device adopts the approximate method of three-point bending to obtain the bending radius R, but the bending radius R does not match the reality, and the accuracy is not enough. In addition, the current test device cann...
