Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of OLED screen detection equipment, and more specifically to an OLED screen crimping and lighting fixture. Background Art
[0002] OLED has the advantages of bright colors and low power consumption. Its display technology has the characteristics of self-luminescence. Through a very thin organic material coating and a glass substrate, when current passes through, these organic materials will emit light. Not only does the display screen have a large viewing angle, but because there is no LED backlight, not only can power consumption be reduced, but in screen application design, it can also be bent, so it can be used in a wider range of designs, such as curved screens, under-screen fingerprint recognition, etc. The existing flexible display technology represented by OLED (organic light-emitting diode) has become a new trend in the industry. Such newly produced products need to be tested to eliminate defective products and reduce the defective rate of subsequent finished products.
[0003] However, when testing the screen, the screen with a flexible circuit board is usually placed in a testing jig, and the flexible circuit board can be electrically contacted with the testing jig for alignment, that is, the screen to be tested is fixed by fixing the flexible circuit board, thereby facilitating the detection. However, the existing testing jig for screen automatic machines lacks a fixed limit for the screen to be tested, and needs to be fixed manually, which is cumbersome to operate and the fixation is not stable enough, resulting in poor contact of the flexible circuit board of the screen to be tested. Secondly, the screen to be tested will be affected by dust, reducing the accuracy of the detection. To this end, we propose an OLED screen crimping and lighting jig to solve the above problems.
