Abstract

A photosensitive assembly, comprising a filter film and a light sensing circuit, wherein the light sensing circuit receives an optical signal that penetrates through the filter film; the filter film comprises a liquid crystal structure, wherein the liquid crystal structure comprises liquid crystal, the liquid crystal constitutes a light portion and a light shielding portion of the filter film according to different liquid crystal deflection angles, and a light transmitting portion is spaced apart from the light shielding portion. In the present invention, by using liquid crystal as a material of the light shielding portion of the filter film, the rotation angle of liquid crystal can be changed according to requirements, an all-phase image can be obtained, and the captured range is larger. Moreover, the shape of the light shielding portion can be adjusted according to requirements, and the sharpness of an obtained picture can be adjusted, and an image can be acquired more flexibly.

Description

technical field

[0001] The invention relates to a photosensitive assembly, in particular to a photosensitive assembly used to acquire images. Background technique

[0002] Traditional photosensitive components acquire images through the combination of lenses. Due to the combination of multiple lenses, the size of the photosensitive component is large. However, the existing electronic products are becoming more and more thin and light. Development requirements, while the existing photosensitive components have certain limitations.

[0003] In order to solve the problem of large volume of traditional photosensitive components, a planar photosensitive component is proposed, which does not require multiple lens combinations, and obtains images through a planar grating placed in front of the photoelectric sensing element. The existing planar photosensitive component has a single grating pattern, and the distance and direction of the object that can be photographed and the clarit...
