AI Technical Summary
When the existing OLED display screens are bent in FPC soft board, the T-shaped light-shielding tape is prone to peeling and lifting from the FPC soft board, resulting in a decrease in connection stability and an increase in bending rebound force.
A fully-fitting OLED display assembly is designed, adopting structures such as glass plate, polarizer, foam layer, edge sealing layer and flexible connection part, and a crystal film is pressed on the first and second connection terminals to reduce the stability of the connection position and the pulling rebound force after bending.
It effectively prevents the bent glass plate and FPC soft plate from peeling off and lifting from the FPC soft plate, reduces the bending rebound force at the connection position, and achieves a further light-shielding effect through the sealing layer.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of display screens, and in particular relates to a fully laminated OLED display screen assembly. Background Art
[0002] With the rapid development of the display technology field, the market requirements for display products are getting higher and higher. Compared with LCD screens, OLED screens have the characteristics of active luminescence, lightness, fast response speed, rich colors, and high resolution. Flexible OLEDs can be bent for use. During use, the FPC soft board may be bent. Since there is a certain step between the FPC and the screen body, there will be bending rebound stress at the position where the T-shaped light-shielding tape is attached to the step. After bending, the T-shaped light-shielding tape is prone to peeling off and warping from the FPC soft board.
[0003] In view of this, the present utility model is proposed. Utility Model Content
