LENS ASSEMBLY, OPTICAL IMAGING SYSTEM, CAMERA MODULE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/173848
Kind Code:
A1
Abstract:
A lens assembly (100), an optical imaging system (200), a camera module (300), and an electronic device. The lens assembly (100) comprises: a carrier layer (10), the carrier layer (10) having a first surface (11), and the first surface (11) being a curved surface; a zoom layer (30), the zoom layer (30) being disposed on the first surface (11) of the carrier layer (10); a flexible layer (50), the flexible layer (50) being arranged on the side of the zoom layer (30) away from the carrier layer (10); and an actuator (713), the actuator (713) being carried on the flexible layer (50), and the actuator (50) being used for driving the flexible layer (50) to undergo a deformation, thus causing an elastic deformation in the zoom layer (30), thereby changing the focal length of the lens assembly (100). The lens assembly (100) has a larger range of focal length change and has a larger light-passing aperture.
