Embedded programmable multi-wave shape PDLC (polymer dispersed liquid crystal) driving power supply and control method

Abstract

The invention relates to an embedded programmable multi-wave shape PDLC (polymer dispersed liquid crystal) driving power supply and a control method, wherein a signal collecting module collects an output signal of a PDLC in real time and sends the output signal to an ARM (Advanced RISC Machines) control module, the ARM control module outputs a control signal to a signal generating module, the output signal of the signal generating module is modulated by a signal modulating module and is amplified by a power amplifying module, and the amplified signal is sent to a boosting module to be boosted so as to drive an LCD (liquid crystal display) touch screen. According to the invention, the polymer dispersed liquid crystal material is driven to generate an electric control phenomenon on the light, and a single path is adjustable and controllable, the output signal of the PDLC is collected and displayed on the touch screen. The system of the invention provides an experiment foundation for research on photoelectric properties of PDLC material, and the system integrates such functions as driving the power supply, controlling and adjusting the signal, displaying the wave shape and collecting data, and the like; besides, the system is small in volume, easy to control and convenient and flexible in application.

Description

technical field [0001] The invention relates to a polymer dispersed liquid crystal drive technology, in particular to an embedded programmable multi-waveform PDLC drive power supply and a method for realizing a control system. Background technique [0002] Polymer dispersed liquid crystal (PDLC) is a new type of optical material formed by dispersing liquid crystal droplets in a solid polymer matrix. Those that are weak to display information do not need polarizers and alignment layers, and the thickness is not strictly limited. It has unique advantages such as simple fabrication, fast switching response speed, and low cost, and has attracted much attention.
