Polaroid, display panel and display device

Abstract

The invention provides a polaroid, a display panel and a display device, relates to the technical field of display, and prevents a visible area of a polaroid from generating bubbles. The polaroid comprises a visible area and a boundary area, and a notch is formed in the boundary area; when the bonding surface of the polaroid is attached to the touch sensor, the first edge of the circuit board on the touch sensor is located in the boundary area and is opposite to the second edge of the boundary area, the boundary area comprises a protruding region covering the circuit board, the two sides of the protruding area in the direction of the first edge are intersected with the first position and the second position of the touch sensor, the boundary area comprises a first area which is located on one side, away from the second position, of the first position, the boundary area comprises a second area located on one side, away from the first position, of the second position, the notch is locatedbetween the first edge and the second edge, and the notch extends from the first area to the second area. The polaroid is mainly arranged in the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a polarizer, a display panel and a display device. Background technique [0002] In the flexible OLED panel MDL (module) process, it is necessary to set the bonding area (binding area) of the polarizer (Polarizer, POL) on the touch sensor (Touch sensor). [0003] Among them, such as figure 1 As shown, the bonding area of ​​the polarizer 1 includes a VA area (visible area) and a border area, the VA area is attached to the touch sensor 2, and a flexible printed circuit board 3 (Flexible Printed Circuit, FPC) is attached between the border area and the touch sensor 2 ), which causes the bonding surface between the polarizer 1 and the touch sensor 2 to have a height difference compared with the contact surface between the polarizer 1 and the flexible circuit board 3, so that the polarizer produces a slope 11 extending from the contact surface to the bonding surface , Air bubbles 1...

[0003] Among them, such as figure 1 As shown, the bonding area of ​​the polarizer 1 includes a VA area (visible area) and a border area, the VA area is attached to the touch sensor 2, and a flexible printed circuit board 3 (Flexible Printed Circuit, FPC) is attached between the border area and the touch sensor 2 ), which causes the bonding surface between the polarizer 1 and the touch sensor 2 to have a height difference compared with the contact surface between the polarizer 1 and the flexible circuit board 3, so that the polarizer produces a slope 11 extending from the contact surface to the bonding surface , Air bubbles 12 are likely to be generated in the gap between the slope 11 and the flexible circuit board 3. Since the boundary area of ​​the polarizer 1 is narrow, the slope 11 will extend to the VA area, so that the air bubbles 12 will extend to the VA area, resulting in the air bubbles. Defects such as vision and light leakage
