液晶显示器（LCD液晶显示面板）和LCD模块（LCM液晶显示模块）的开发与设计

三相步进电机的三相六拍工作方式，正转的绕组通电顺序：A、AB、B、BC、C、CA、A，反转的通电顺序：A、AC、C、CB、B、BA、B、A。 由于步进电机转子有一定的惯性以及所带负载的惯性，故步进电机的工作过程中不能及时的启动和停止，在启动时应慢慢的加速到预定速度，在停止前应逐渐减速到停止，否则，将产生失步现象。 步进电机的控制问题可总结为两点： 1、产生工作方式需要的时序脉冲； 2、控制步进电机的速度，使它始终遵循加速、匀速、减速的规律工作。 -Three-phase three-phase stepper motor six shot work, is to order the winding power: A, AB, B, BC, C, CA, A, reverse the order of power: A, AC, C, CB, B, BA, B, A. As the stepper motor rotor has a certain degree of inertia, as well as brought about by the inertia load, the stepper motor during the course of work should not start and stop time, start to be slowly accelerated to a predetermined speed, the stop should be to slow down gradually to the stop, otherwise, will result in out-of-step phenomenon. Stepper motor control problems can be summarized in two points: one, resulting in the need to work the timing pulse 2, control the speed of stepper motor, so that it always followed acceleration, velocity, deceleration of the law of the work.

本装置是一个以HT46R71D 为主芯片，配合传感器组成的汽车轮胎气压检测装 置，最终取高三位有效值于LCD 显示，有四种显示单位供切换（Psi、Bar、Kpa、 Kgf/cm2）。本装置仅为参考范例，使用时，为提高准确度，建议多量测些组数 据来构建Sensor Output Voltage - Discharge Time (V-T)表格，并作相应校准。-This device is a HT46R71D-based chips, with sensors detecting vehicle tire pressure devices, and ultimately take the high-three RMS in LCD display, there are four types of display units for switching (Psi, Bar, Kpa, Kgf/cm2). Only reference to an example of the device, when used to improve the accuracy of the proposed多量measured set of data to build more Sensor Output Voltage- Discharge Time (VT) forms, and the corresponding calibration.
