Description
Technical Field
The present disclosure relates to the field of array substrate technology, and in particular, to a flexible array substrate, a display panel, a display screen, and an electronic device.
Background
Some display panels include a flexible array substrate including an anode and a cathode, and when external ambient light is irradiated to the anode and the cathode, emission occurs, and the existence of reflected light reduces the contrast of the display panel, which seriously affects the viewing experience of a user.
In order to solve the above technical problems, in the related art, a polarizer is additionally disposed in the flexible array substrate to reduce the reflected light. However, the polarizer is thick, and the thickness of the display panel is greatly increased by using the polarizer, which is not favorable for bending the flexible array substrate. Meanwhile, the maximum light transmittance of the polarizer is low, only about 50%, which seriously affects the luminous quantum efficiency of the flexible array substrate and increases the display power consumption.
