Title:
VARIABLE APERTURE, CAMERA MODULE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/040906
Kind Code:
A1
Abstract:
A variable aperture, a camera module, and an electronic device, which belong to the technical field of communication devices. The variable aperture comprises a first light-transmitting substrate (110), a second light-transmitting substrate (120), a light-transmitting fluid (210), a light-shielding fluid (220), a driving mechanism, and a first light-supplementing member (300). The first light-transmitting substrate (110) and the second light-transmitting substrate (120) are arranged opposite to each other; a sealing chamber is provided between the first light-transmitting substrate (110) and the second light-transmitting substrate (120); the light-transmitting fluid (210) and the light-shielding fluid (220) are flowably arranged in the sealing chamber; the light-transmitting fluid (210) is incompatible with the light-shielding fluid (220); and the light-transmitting fluid (210) and the light-shielding fluid (220) are used to form a light-transmitting region and a light-shielding region. The light-shielding region is arranged around the light-transmitting region; the driving mechanism is used to drive the light-transmitting fluid (210) and the light-shielding fluid (220) to flow; the flowing of the light-transmitting fluid (210) and the light-shielding fluid (220) may change the area of the light-transmitting region and the light-shielding region; and when the area of the light-transmitting region is less than a preset area, the first light-supplementing member (300) emits light.
