Abstract

The invention discloses a batch bending testing device of a flexible display screen. The testing device comprises a plurality of bent rolling shafts which are arranged in parallel, wherein a first driving membrane layer and a second driving membrane layer are arranged among the plurality of bent rolling shafts; the first driving membrane layer and the second driving membrane layer are leveled and are wound on the external circular surfaces of all bent rolling shafts in sequence, and are separated on the first bent rolling shaft and the final bent rolling shaft; a tested flexible display screen is arranged between the first driving membrane layer and the second driving membrane layer; each bent rolling shaft is driven to rotate so that the first driving membrane layer, the second driving membrane layer and the flexible display screen are driven to be subjected to a bending test synchronously along the external circular surfaces of the plurality of bent rolling shafts. The two driving membrane layers provided by the invention are used for bending the tested flexible display screen inwards sometimes and outwards sometimes along the external circular surfaces of the plurality of bent rolling shafts under the driving of a first unwinding roller and a second winding roller; an accumulation effect is not generated in a bending process, and requirements on the bending test of the flexible screen by mass production are met.

Description

technical field [0001] The invention relates to the technical field of flexible display screens, in particular to a batch bending test device for flexible display screens and a testing method thereof. Background technique [0002] Flexible display devices are formed by forming TFE and OLED devices on flexible substrates, so as to achieve the effect of normal display even when folded or bent, and have broad application prospects in portable electronic devices and other fields. At present, flexible display products with fixed curved surface displays have appeared on the market, and products with flexible displays will soon enter mass production. However, the bending test part of the flexible screen is not perfect. The current common bending test method can only test a single screen or small batches, and cannot perform bending tests on a large number (or all) of the screens. Therefore, for mass-produced products , there is an urgent need for a method that can realize batch ben...
