Abstract

The invention discloses a display panel testing device and system, and the device comprises a pedestal and a testing assembly, and the pedestal is used for being fixedly connected with at least part of a display panel; the test assembly comprises a rotatable plate and a drawing device. The rotatable plate is rotatably connected with the base so as to bend a to-be-tested area of the display panel to a preset angle; the drawing device is arranged on the rotatable plate and used for fixing a to-be-tested area of the display panel and providing tension for the to-be-tested area so as to carry outa drawing test when the to-be-tested area is bent to a preset angle. By means of the mode, the drawing force borne by the display panel in the bending process can be simulated, and the accuracy of drawing test data is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a testing device and system for a display panel. Background technique [0002] With the development of display technology, the public has higher and higher requirements for screens with a high screen-to-body ratio. Compared with existing mobile devices, mobile devices with a high screen-to-body ratio have narrower borders, wider display areas, and smaller dimensions under the same screen size. [0003] Pad-Bending technology is one of the key technologies to realize the narrow frame of flexible OLED display panel. During the Pad-Bending process of the flexible OLED display panel, the bending of the bending area is involved. During the bending process, tension is often caused on the bending area, and when the tension exceeds a certain value, it is easy to cause circuit cracks on the display panel, resulting in a decrease in the reliability of the display panel. There...
