Problems solved by technology
[0006] The above-mentioned bending test method has the following defects, because the sample to be tested usually includes a substrate, an anode disposed on the substrate, an organic light-emitting layer disposed on the anode, an electron transport layer disposed on the organic light-emitting layer, and an electron transport layer disposed on the electron transport layer. For the multi-layer structure of the cathode and other multi-layer structures, due to clamping, the surface tension of materials with different Young’s moduli cannot be released during the bending process, and material delamination will occur, which affects the The accuracy of the bending test results cannot truly reflect the bending characteristics of the sample to be tested

The invention provides a bending test device and a bending test method for a flexible display panel. According to the device, air holes are evacuated, so that the flexible display panel is adsorbed and fixed, a control motor controls a clamping plate to reciprocate, so that the flexible display panel forms different bending diameters, bending test of the flexible display panel is finished, the flexible display panel cannot be clamped by the aid of clamping heads, so that the problem of laying of materials of different layers caused by surface tension without being released due to clamping of the clamping heads is avoided when materials of the flexible display panel is bent, bending characteristics of the flexible display panel are really reflected, and bending test accuracy is effectively improved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a bending test device and a bending test method of a flexible display panel. Background technique [0002] Flat-panel display devices have many advantages such as thin body, power saving, and no radiation, and have been widely used. Existing flat panel display devices mainly include liquid crystal display devices (Liquid Crystal Display, LCD) and organic light emitting diode display devices (Organic Light Emitting Display, OLED). [0003] Organic light-emitting diode display devices have excellent characteristics such as self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response speed, flexible panels, wide operating temperature range, and simple structure and manufacturing process. It is considered as an emerging application technology for the next generation of flat panel displays. [0004] Flexible OLED panels are an important...
