Embodiment Construction

[0043] The terms "first", "second" and the like used herein do not specifically refer to a sequence or sequence, but are only used to distinguish elements or operations described with the same technical terms.

[0044] Figure 1A is a schematic diagram illustrating some components of a display device according to an embodiment. Please refer to Figure 1A , the display device 100 includes a light emitting source 110 , a light control film 130 and an optical component 120 . For simplicity, not all components of the display device 100 are shown here, for example, the display device 100 may also include a liquid crystal panel and the like.

[0045] The light emitting source 110 includes a plurality of light emitting diodes 111 , and the light emitting direction 112 of these light emitting diodes 111 points to the optical component 120 . The size of the light emitting diode 111 can be millimeter level, micron level or nanometer level. In some embodiments, the light emitting diode...

Abstract

The invention provides an optical assembly. The optical assembly comprises a first optical film and a second optical film, the first optical film is provided with a plurality of first microstructures,and the first microstructures are arranged in a checkerboard mode with a first direction as the reference. The second optical film is provided with a plurality of second microstructures, the second microstructures are arranged in a chessboard mode with a second direction as the reference, and the included angle between the first direction and the second direction is larger than 30 degrees and smaller than 60 degrees. Therefore, the phenomenon of uneven display can be avoided.

Description

technical field [0001] The present disclosure relates to an optical component capable of alleviating display unevenness (mura). Background technique [0002] In a general backlight module, the light source will be equipped with multiple optical films, and these optical films may include a prism layer, a diffusion layer, a light guide plate, and so on. There may be some microstructures in some optical films. When the microstructures of the upper and lower optical films are the same, such as repeated stripes, it will produce moire effect, which will cause uneven display. How to solve this problem , a topic of concern to those skilled in the art. Contents of the invention [0003] An embodiment of the invention provides an optical component, including a first optical film and a second optical film. The first optical film has a plurality of first microstructures, and the first microstructures are arranged in a checkerboard pattern based on the first direction. The second op...
