OLED screen bending testing equipment and testing method

Abstract

The invention provides OLED screen bending testing equipment and testing method. The testing equipment comprises a cabinet body and a bending mechanism, wherein the bending mechanism comprises a mobile device, a placement carrying platform, a bending device and a tension sensing device; the placement carrying platform comprises a carrying platform I and a carrying platform II for fixing the two ends of an OLED flexible screen; the mobile device, the bending device and the tension sensing device are arranged between the carrying platform I and the carrying platform II; the bending device is fixed on the mobile device; the bending device comprises a bending roller; the tension sensing device comprises a tension sensor, a tension control shaft and an angle control shaft; the angle control shaft is located below the bending roller and is located on one side of the tension control shaft; and the two ends of the tension control shaft and the tension sensor are fixedly connected on the mobiledevice, so that left and right movement is achieved. The OLED screen bending testing equipment and testing method have the advantages that the bending experiment efficiency is higher, the experimental result is more stable and objective, the displacement precision is high, and the universality is high.

Description

technical field [0001] The invention relates to the technical field of OLED screen testing, in particular to a bending test device and a testing method for OLED screens. Background technique [0002] Liquid crystal display technology has changed from LCD hard screen to OLED flexible screen. The popularity of OLED flexible screens is not only brought about by low power consumption and high display effects, but the greater revolutionary improvement is flexibility, which has changed the fundamental view of human beings on display screens. It is no longer a flat display, but can be displayed at various angles. All-round flexible display. In the initial stage of flexible display development, the collection of various physical parameters after bending is of great help to the entire product cognition and later improvement. [0003] However, at present, there are still very limited equipment for flexible bending of OLED flexible screens, and the market is basically in a blank stat...

AI Technical Summary

Problems solved by technology

[0003] However, at present, there are still very limited equipment for flexible bending of OLED flexible screens, and the market is basically in a blank state. Most of them are manual tooling, which require manpower to maintain and verify by manpower. The bending effect cannot be maintained, the repeatability (reproducibility) of the bending effect is unstable, and other problems. The folding screen test device released by Samsung recently can test OLED flexible screens, but its device is a bending test of the whole machine and can only Test the 180-degree bending life of OLED flexible screens, the test range is very limited, and the versatility is not strong
