Abstract

The invention provides an aperture structure, a camera and an electronic device. The aperture structure comprises a substrate and a plurality of electrochromic units, wherein the plurality of electrochromic units are arranged on the substrate; and the plurality of electrochromic units are arranged in an array on the substrate, and each electrochromic unit is used for changing the light transmittance of the electrochromic unit after being applied with voltage, so as to change the light transmittance of the aperture structure. According to the aperture structure, the camera and the electronic device provided by the embodiment of the invention, the states of different electrochromic units can be changed according to requirements, so that the area of the light-transmitting part of the aperturestructure is changed, the controllability of the aperture structure is enhanced by adopting the plurality of electrochromic units, and the aperture structure can be conveniently arranged on electronic devices such as a mobile phone and a notebook computer.

Description

technical field

[0001] The present application relates to the technical field of optical imaging, and more specifically, to an aperture structure, a camera and an electronic device. Background technique

[0002] With the rapid development of economy and technology, camera modules have been integrated into various consumer electronic devices. For example, a mobile phone or a laptop, etc. These consumer electronic devices have relatively strict requirements on the size of the camera module. The aperture of the traditional camera module is a leaf aperture. However, the leaf aperture includes a group of overlapping sheet-like parts that adjust the aperture in the aperture and drive these overlapping sheets. It is precisely because of the arrangement of overlapping sheet parts and mechanical parts that the size of the leaf aperture will be too large, so it is difficult to meet the miniaturization needs of consumer electronic devices such as mobile phones or notebook computers. ...
