Abstract

The embodiment of the invention provides an optical image acquisition device and electronic equipment, and the thickness of a filtering function layer is reduced through employing a substrate-free coating technology, thereby reducing the thickness of the optical image acquisition device. The optical image acquisition device comprises a lens assembly which comprises a lens, the lens is provided with at least one plane surface, the plane surface is plated with a light filtering film layer, the lens is used for converging light signals, and the light filtering film layer is used for filtering outlight signals of non-target wave bands and light signals penetrating through target wave bands; and the sensing chip is arranged below the lens assembly, and the sensing chip is used for imaging according to the optical signals converged by the lens.

Description

technical field [0001] The embodiments of the present application relate to the field of electronics, and more specifically, to an optical image acquisition device and electronic equipment. Background technique [0002] With the popularization of camera and optical fingerprint functions of smart terminal devices, such as mobile phones, tablet computers, smart watches, etc., the requirements for optical image acquisition devices such as optical cameras are getting higher and higher. Optical filters are used to pass light in a specific wavelength range and are one of the important components of optical cameras. Traditional optical filters are used to achieve light filtering by coating the surface of the base glass. However, the thickness of traditional optical filters cannot be made too thin due to the limitation of the strength of substrate materials such as white glass and blue glass, which limits the thickness of optical cameras to a large extent. For optical image acquis...
