Thin film aperture and aperture module

Abstract

The embodiment of the invention provides a thin film aperture and a thin film module, and relates to the field of optics, wherein the thin film aperture comprises a first substrate, a second substrate, an aperture layer and a transparent electrode, the first substrate and the second substrate are oppositely arranged, the aperture layer is located between the first substrate and the second substrate, and the transparent electrode is located at at least one side of the aperture layer and is used for inputting an electric signal to the aperture layer. The aperture layer comprises colored electrophoretic particles flowing freely and transparent suspension liquid, and the colored electrophoretic particles directionally move in the transparent suspension liquid under the action of electric signal, so that the aperture layer is in a full-light-absorption state, a semi-light-absorption and semi-light-transmission state and a full-light-transmission state. According to the scheme, the thin filmaperture can selectively present light absorption and light transmission states, the aperture is changed to change the luminous flux, the size of the aperture is greatly reduced, and the light and thin design of the aperture can be realized.

Description

technical field [0001] The embodiments of the present application relate to the field of optical technology, and in particular, relate to a thin-film aperture and an aperture module. Background technique [0002] The lens of a digital camera is used to capture object information. Generally speaking, the aperture is a necessary optical element in the lens to control the amount of light passing through the lens. [0003] In the traditional mechanical aperture, there are shading blades in the aperture, and the closing of the shading blades is realized by rotating to change the size of the aperture of the aperture, thereby changing the amount of light passing through the aperture of the aperture. However, the shading blades are relatively thick and occupy a large space, which is unfavorable for applications in portable electronic devices and other products that require high thinness. Contents of the invention [0004] The purpose of this application is to at least solve one o...
