Serial display modules

Character LCD Module is type thin film transistor liquid crystal display, which is "truecolor" (TFT). TFT LCD for each pixel has a semiconductor switch, each pixel can through the point of pulse directly control, which are relatively independent, each node and can be continuous control, not only improves the display speed, and can precisely control levels, TFT LCD color so more true. TFT LCD display screen is the feature of good brightness, high contrast, administrative levels feels strong, bright color, but there are also more power consumption and high cost.

TFT (Thin Film Transistor) Thin Film field effect Transistor, namely belongs to one of the active matrix liquid crystal display. It can be "active" to control of individual pixels on the screen, this can greatly improve the reaction time. General TFT relatively fast response time, about 80 milliseconds, and large visual Angle, generally can reach 130 degrees.
TFT LCD polarity reversal mode:
The driving voltage of liquid crystal molecules cannot be fixed at a certain values, otherwise, time is long, the Serial display modules polarization phenomenon will happen, so as to gradually lose their optical properties. Therefore, in order to avoid damage to the characteristics of the liquid crystal molecules of the liquid crystal molecules, the driving voltage polarity transformation must be conducted, it is need to display the voltage to the liquid crystal display is divided into two kinds of polarity, one is normal polarity, the other is a negative polarity.
