Abstract

In this paper, an arrayed liquid-crystal microlens driven by a high-precision multi-channel electronic signal is proposed, which can generate a set of alternating current (AC) voltage driving and controlling signal according to user input. The device is designed based on the basic microstructure of a liquid-crystal microlens array, which can be approximated as a set of capacitance. Through an electronic scanning and driving method, not only the volume of the driving and controlling device for liquid-crystal microlenses is reduced remarkably, but also the independent driving and controlling channel is also increased obviously. The frequency of the driving and controlling signal can be changed by a control software. The output voltage signal can be better connected with a large scale liquid-crystal microlens array through FPC soft line. Experiments demonstrate that the electronic device can generate 384 frequency-variable high-precision independent driving and controlling voltage signals, so as to demonstrate a good application prospect for the partition and block regulation of a large area liquid-crystal microlens arrays.
