Standard Single TFT Display Viscosity Of Liquid Crystalline Materials Oct 10, 2017

1, Standard Single TFT Display of the back structure in the liquid crystal display, LCD screen is generally as a whole and exist. This is because of the specificity of liquid crystal devices and the need for special tools for connection and assembly, plus the difficulty of operation technology is very big and other reasons, manufacturers of liquid crystal display screen, connectors, driving circuit PCB circuit boards, backlight lights and other components with steel plate closed, leaving only a backlight light plug and drive signal transmission socket.It can be seen that the way of this component increases both the reliability of the work and the unnecessary accidental loss caused by the arbitrary disassembly of the user. LCD manufacturers only need to put the backlight lamp Plug and drive signal Plug and external circuit board can be connected, so that the production process has become much simpler. For Standard Single TFT Displays, the number of backlighting is different depending on the size of the screen and the requirements of the display.

2. The main technical indicators of the LCD screen directly determine the quality of the display, the current market on the Standard Single TFT Display equipment prices and the use of LCD screen has a direct relationship.

(1) Pixel spacing

The Pixel spacing (pixelpitch) of the Standard Single TFT Displays the same meaning as the CRT's point distance (dot pitch). You know, the point distance of CRT (cathode ray tube) display is the distance between adjacent two pixels, but due to different resolution mode and different field refresh rate, the actual point distance of the image is different, so the CRT display usually indicates the minimum point distance. The liquid crystal display is different, its pixels are fixed, there is no maximum and minimum, so the pixel spacing marked is the inherent point distance.

This distance determines the higher the resolution of the LCD screen, the smaller the pixel spacing, and conversely the greater. It can be seen that pixel spacing is really an indicator that can affect the image's fineness, for CRT monitors, of course, the smaller the better, but for liquid crystal display, because the principle of the image is based on light transmission to achieve, so the size of the pixel spacing depends on this display way to achieve the greatest possible, Therefore, it is not possible to pursue the pixel spacing of liquid crystal displays like the point distance of the CRT. In fact, as long as the screen size and resolution are the same, the pixel spacing of the LCD screen is basically the same.

(2) Response time

Because of the viscous characteristics of liquid crystal materials, the display will be delayed. The response time is a technical index reflecting the speed of the signal reflected by each pixel, and the smaller the index is. The response time consists of two parts, one of which is the delay time TR (also known as the rise time) of the input signal when the pixel point is dimmed by a light turn. The other is the delay time (also known as the Descent time) for the input signal when the pixel point is illuminated by the Damin, which is the response time of the LCD, and the unit of measurement is MS (ms).
