Problems solved by technology

[0002] At present, virtual / augmented reality display devices usually have a larger display viewing angle in order to pursue immersion. Therefore, when the display screen is magnified by a lens, its pixels will be magnified several times, making it easy for the human eye to see the display details of a single pixel. , resulting in a decrease in picture clarity, that is, the currently used display screens generally can only meet the requirements of human eyes for picture clarity when viewing directly
The main reason for the above problems is that the black matrix designed to cover the irregular driving lines on the display screen is relatively wide. After being enlarged by the VR imaging lens, the width of the black matrix reaches the limit of human visual resolution, so that the human eye can feel The space matrix effect formed by the black matrix reduces the display quality. This phenomenon is called the screen window effect

Abstract

The present invention relates to the field of display technology, and proposes a display device, which includes a display screen, and an optical film structure arranged on the light-emitting side of the display screen, and the optical film structure includes a base material layer and a first microlens The array layer, the substrate layer has a first surface and a second surface designed oppositely; the first microlens array layer is arranged on at least one of the first surface and the second surface, and the first microlens array The layer includes a plurality of microlenses arranged in sequence, the size of the microlenses is smaller than the size of the sub-pixel, and the edges of adjacent microlenses overlap each other. The display device can improve the screen window effect.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an optical film structure, a method for forming the optical film structure, and a display device equipped with the optical film structure. Background technique [0002] At present, virtual / augmented reality display devices usually have a larger display viewing angle in order to pursue immersion. Therefore, when the display screen is magnified by a lens, its pixels will be magnified several times, making it easy for the human eye to see the display details of a single pixel. , resulting in a decrease in picture definition, that is, the currently used display screens generally can only meet the requirements of human eyes for picture clarity when viewing directly. The main reason for the above problems is that the black matrix designed to cover the irregular driving lines on the display screen is relatively wide.
