Abstract
The invention relates to a flexible back board and a manufacturing method thereof, and a flexible display screen. The flexible back board comprises a flexible substrate, a buffer layer, an active layer, a gate insulating layer and a gate metal layer which are stacked in sequence; the gate insulating layer and the gate metal layer are on the two sides of the active layer to form stage corners; andthe flexible back board also comprises organic insulating layers adsorbed on the two sides of the active layer in a direction parallel to conductive channels. According to the flexible back board andthe flexible display screen provided by the invention, by setting the organic insulating layers on the two sides of the active layer, the high defect state between the stage corners of the gate insulating layer and the active layer caused by repeated bending can be blocked by the organic insulating layers, and electric leakage channels are eliminated, thereby ensuring display effect stability of the flexible display screen.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a flexible backplane, a manufacturing method thereof, and a flexible display device. Background technique [0002] With the continuous development of display technology, flexible display screens are being used more and more widely. Flexible displays are often used in flexible products including wearable devices due to their characteristics of rollability, wide viewing angle, and portability. [0003] In the process of realizing the above technology, the inventors found that there are at least the following technical problems: [0004] like figure 1 As shown, for a flexible display that is bent along the W direction, its flexible backplane will generate a leakage channel in the L direction, causing the drain-source current to increase, resulting in Mura (uneven display), dark spots, Flicker (flicker), etc. The problem affects the display effect.
