Abstract

The application provides an image sensing pixel unit, an image sensor, and a lens module; the image sensing pixel unit includes a substrate, a photosensitive element, and an electrowetting lens, and the electrowetting lens includes a cavity, and the two opposite ends of the cavity are The light-transmitting surface, the cavity is filled with a first light-transmitting liquid and a second light-transmitting liquid that are immiscible with each other, the first light-transmitting liquid is a conductive liquid, and the second light-transmitting liquid is a non-conductive liquid. A first conductive layer is provided, a second conductive layer is provided at one end of the cavity close to the second light-transmitting liquid, the second conductive layer is spaced apart from the first conductive layer, and the second conductive layer is a light-transmitting layer. The chief ray angle is adjusted through the electrowetting lens, so as to match the change requirement of the zoom lens on the chief ray angle, so as to improve the imaging quality.

Description

technical field [0001] The present application belongs to the technical field of image capture, and more specifically relates to an image sensing pixel unit, an image sensor and a lens module. Background technique [0002] A microlens array is generally installed on the image sensor, so that each pixel unit of the image sensor forms a microlens to gather light, increase the photoelectric conversion efficiency of the photosensitive element, and reduce signal crosstalk between adjacent pixel units. The current microlens array is generally formed by etching with a polymer coating. Once the microlens array structure is formed, the chief ray angle of the microlens is fixed. The telephoto lens module and the short-focus lens module require different principal ray angles of the microlenses, which leads to a mismatch between the chief ray angles of the microlenses in the zoom lens module, causing shadows on the screen and affecting image quality.
