However, for the following: f The environment where most terminal devices / display devices are operated on the desk, or from the perspective of local environmental protection, if the trend of energy saving is predicted, the CRT still has many problems in terms of space utilization or energy consumption. For portable applications with the advantages of high day quality, low ^ θ electric power, thin mass production, low voltage drive, and small size, the use of CRT has been eliminated. This point, for thin-Film Transistor Liquid Crystal Display (referred to as TFT-LCD), will have great expectations. Liquid crystal displays (Liquid Crystal Display, LCD for short) were first applied to electronic computers and electronic clocks in the early 1970s. Later, due to the discovery of a variety of new optoelectronic effects and improvements in driving technology, it has the advantages of high daylight quality, low power consumption, thin mass production, low voltage driving, and small size. It has been widely used in small and medium-sized enterprises. Portable TVs, video phones, camcorders, notebook computers, desktop monitors, and projection color TVs have gradually replaced CRTs and are one of the most attractive product components. However, the production process of LCD is not so easy, especially when there is no uniform standard for LCD resolution and input signals.
