Ⅰ. Introduction
1. Objective
To understand the structure of TFT-LCD, design a hardware filter and write a
device driver to control the filter to identify changing image information.

2. What is TFT-LCD
LCDs are divided into simple Matrix method ones and Active Matrix method ones based on driving methods. In the case of Matrix Types (TN, STN), scanning electrodes and signaling electrodes are arranged in the form of XY and the crossing parts are used as display pixels and thus their element compositions are simple. TN, STN LCDs belong to Matrix Types and STN LCDs are used for uses with high display densities and TN LCDs are used for uses with low display densities.
Active matrix type is divided into three terminal element ones made by installing a thin film transistor (TFT) on every display pixel and two terminal element ones made by installing elements that have non-linear(diode) properties to currents and voltage. These can make high quality screens because every single pixel is directly driven and are used for color displays.
