摘要： A method for providing auto focus for camera module that is electrically tunable using liquid crystal optical element is provided. The liquid crystal optical element includes substrate layers, insulating layer, three electrodes, liquid crystal layer between the substrate layers, and voltages applied between electrodes to control the optical power of the liquid crystal layer. The liquid crystal layer is coupled onto a camera module for provide auto focus on object located between 10 cm to infinity, achieving a response time at most of about 600 milliseconds. Tuning for the predetermined focal length is provided for liquid crystal optical element when object is located between 10 cm to infinity.

摘要： A projection apparatus including an illumination system, a light valve, and an imaging system is provided. The illumination system is for emitting an illumination beam. The light valve is disposed on a transmission path of the illumination beam for converting the illumination beam into an image beam. The imaging system includes a projection lens and an electrically tunable focusing lens. The projection lens is disposed on the transmission path of the image beam. The electrically tunable focusing lens is disposed on the transmission path of the image beam. The electrically tunable focusing lens changes a focal length thereof by electricity but not by a mechanism moving positions of lenses.

摘要： A liquid crystal (LC) lens structure and a method of driving same are disclosed. The LC lens structure includes an upper substrate, a lower substrate, a liquid crystal and polymer composite film, and an LC layer. The upper substrate is provided with a first conducive layer and a first alignment layer; and the lower substrate is provided with a second conductive layer and a second alignment layer. The liquid crystal and polymer composite film is arranged at one side of the first alignment layer to form a first lens, and the LC layer is arranged between the liquid crystal and polymer composite film and the second alignment layer to form a second lens. By building the liquid crystal and polymer composite film in the LC lens structure, it is able to realize an LC lens with low operating voltage and large focusing range.
