Title:
VIEWING ANGLE CONTROLLABLE MODULE, VIEWING ANGLE CONTROL METHOD AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/238345
Kind Code:
A1
Abstract:
A viewing angle controllable module, a display, an electronic device, a viewing angle control method, a storage medium and a program product. The viewing angle controllable module (195) comprises an upper electrode layer (1952), a lower electrode layer (1955), and a lens array layer (1953) and a liquid layer (1954) which are provided in a stacked manner between the upper electrode layer (1952) and the lower electrode layer (1955). The light incident on the module (195) exits the module (195) after passing through the liquid layer (1954) and the lens array layer (1953), and is refracted at the interface between the liquid layer (1954) and the lens array layer (1953); and when the voltage between the upper electrode layer (1952) and the lower electrode layer (1955) is different, the refractive index of the liquid layer (1954) is different, and the refracted light exits the module (195) in a different direction, achieving the adjustment of the viewing angle. Further provided are a display and an electronic device which have the module (195), a method for controlling the viewing angle of the display according to the voltage, a storage medium storing a program for implementing the method, and a program product for executing the method.
