Problems solved by technology

[0003] With the development of science and technology, reducing the size of the circuit is the goal of various technology factories. However, if the traditional liquid crystal voltage control circuit is directly integrated into an IC, it often fails to achieve the functions that the liquid crystal voltage control circuit should have, and the control of the liquid crystal is still poor.

Abstract

A liquid crystal glass plate modulation circuit is mainly characterized in that a vibration sensing component is triggered by knocking a glass plate, a first pulse wave is output through a Schmitt trigger circuit and a flip-flop, and a logic judgment component outputs a high voltage or a low voltage according to the first pulse wave and a second pulse wave generated by a pulse wave generation component. And a first transistor, a second transistor and a third transistor are respectively turned on or off according to the high voltage or the low voltage, so that a liquid crystal layer is changed into a first state or a second state. The liquid crystal glass plate modulation circuit can be integrated, can be conveniently applied to a minimized voltage control circuit, and has a better control effect on the liquid crystal layer.

Description

technical field [0001] The invention relates to a modulation circuit for a liquid crystal glass plate, especially a modulation circuit for changing the transparency of the liquid crystal layer by applying high voltage to the positive and negative poles of the liquid crystal layer. Background technique [0002] Traditional liquid crystal voltage control circuits are all high-voltage drive circuits. In order to provide related high-voltage circuits, the design of voltage control circuits composed of various discrete circuit components has considerable stray resistance and capacitance, which is not suitable for miniaturized voltage control circuits. circuit. [0003] With the development of science and technology, reducing the size of the circuit is the goal of various technology factories. However, if the traditional liquid crystal voltage control circuit is directly converted into an IC, the functions of the liquid crystal voltage control circuit are often not achieved, and t...
