Problems solved by technology

When performing automatic optical inspection on flexible screens, due to the large deformation of the flexible screen, the flatness of the flexible screen needs to be corrected to a reasonable tolerance range before the inspection can be performed. If the flatness of the flexible screen is not corrected, It will make it exceed the depth of field range of the detection camera, which will distort the captured picture and cause false detection

Abstract

The embodiment of the invention discloses a leveling device of a flexible screen and a leveling method of the flexible screen, and the device comprises a reference layer which is used for bearing the flexible screen; the easy-to-deform film layer is arranged on the side, away from the reference layer, of the flexible screen, and the orthographic projection area, on the reference layer, of the easy-to-deform film layer covers the orthographic projection area, on the reference layer, of the flexible screen; the magnetofluid layer is arranged on the side, away from the flexible screen, of the easily-deformed film layer, the orthographic projection area, on the reference layer, of the magnetofluid layer covers the orthographic projection area, on the reference layer, of the easily-deformed film layer, and the magnetofluid layer comprises multiple magnetofluids; under the action of the target magnetic field force, at least part of the magnetic fluid in the magnetic fluid layer is switched from the first state to the second state and drives the easy-to-deform film layer to deform, the easy-to-deform film layer generates target pressure facing the flexible screen, and the flexible screen deforms under the action of the target pressure. The overall flatness of the flexible screen is adjusted to be within the first preset threshold value. According to the invention, the flatness of the flexible screen is ensured, and the product yield of the flexible screen is improved.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a leveling device for a flexible screen and a leveling method for a flexible screen. Background technique [0002] With the continuous development of display technology, a display screen prepared by flexible display technology, namely a flexible screen, has received extensive attention. When performing automatic optical inspection on flexible screens, due to the large deformation of the flexible screen, the flatness of the flexible screen needs to be corrected within a reasonable tolerance range before the inspection operation can be performed. If the flatness of the flexible screen is not corrected, It will make it beyond the depth of field range of the detection camera, so that the picture taken is distorted, resulting in false detection. SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide a leveling device for a flexible s...
