Problems solved by technology

In order to be foldable, the thickness of the flexible foldable cover 40' is thin and the hardness is low, so the existence of gaps will cause deformation, bulging, bubbles, etc. around the flexible foldable cover 40' when it is attached to the display panel 20'. Bad, which will seriously affect product appearance and yield
[0005] Therefore, there is an urgent need to provide a polarizer and a flexible and foldable display panel device to improve the technical problems of deformation, bulging, and air bubbles caused by ink gaps when the flexible and bendable cover plate is bonded to the display panel.

Abstract

The present invention discloses a polaroid. The polaroid comprises a first protection layer, a line deviation layer and a second protection layer which are sequentially arranged in a stacked mode, and a light shielding layer is arranged on the side, away from the second protection layer, of the line deviation layer; the light shielding layer is located between the first protection layer and the line deviation layer, and one side surface, deviating from the line deviation layer, of the first protection layer is a flat surface; the light shielding layer is located on the edge of the line deviation layer. The invention further provides a flexible foldable display panel device. According to the polaroid for printing the shading layer in the non-display area, the polaroid is applied to a flexible foldable display panel device, and the phenomena of peripheral deformation, swelling and bubbles caused when a flexible bendable cover plate is attached to a display panel can be avoided.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a polarizer and a flexible and foldable display panel device. Background technique [0002] The development of smart phone terminals has been in ever-changing forms, such as extreme bezels, waterfall screens, off-screen cameras, and foldable forms. Among them, foldable mobile phones have very broad market prospects because they combine the characteristics of tablets and mobile phones and differentiated selling points. [0003] Flexible panels are developed on the basis of OLED (Organic Light Emitting Diode, organic light emitting diode) technology. The cathode is injected and then migrated into the organic light-emitting layer, where they meet to form excitons, and the excitons transfer energy to the organic light-emitting molecules under the action of an electric field and excite the electrons in the organic molecules to transition from the ground state to the excite...
