What is liquid crystal?

Liquid crystal display (LCD) is a kind of display using liquid crystal as material.   What is liquid crystal? In fact, liquid crystal is a kind of material between solid and liquid. When heated, it will appear transparent liquid, and when cooled, it will crystallize into chaotic solid. Liquid crystal is an organic compound with regular molecular arrangement.   According to the different arrangement of molecular structure, liquid crystals can be divided into three types: Smectic liquid crystals similar to clay, Nematic liquid crystals similar to thin matchstick and Cholesteric liquid crystals similar to cholesterol.   The physical properties of these three kinds of liquid crystals are not the same. Nematic liquid crystals of the second kind are used in liquid crystal displays. The molecules are long rods. In the natural state, the long axes of these long rods are roughly parallel.

The development of LCD touch Screen

With the increase of information inquiries from multiple TV stations, many people are talking about LCD touch all-in-one. As a newest PC input device, it is the simplest, convenient, natural and suitable for China’s multiple TV stations. The input equipment for querying national conditions has many advantages such as sturdiness and durability, fast response speed, space saving, and easy communication. In order to facilitate the operation, many people use LCD touch all-in-one computers to replace the mouse or keyboard. When working, we must first touch the screen installed in the front of the display with our fingers or other objects, and then the system locates and selects information input according to the icons or menu units touched by the fingers. The liquid crystal touch all-in-one machine is composed of a touch detection component and a controller; the touch detection component is installed in front of the display screen to detect the user’s touch position and take over and send the controller; and the primary function of the controller is to absorb the touch point detection assembly Touch the information and convert it into contact coordinates, and then send it to the CPU. It can also absorb the commands sent by the CPU and execute them. The touchpad uses pressure-sensitive capacitive touch technology, with the largest screen area. It consists of three parts: the bottom layer is the middle sensor, which is used to monitor whether the touchpad is High plastic material composition. The growth of LCD touch all-in-one technology shows

Why don’t colors look the same across different devices?

It is a common misconception that all electronics should exhibit the same colors, especially with devices with the same make and model. However, this is often not the case. Have you considered what’s actually causing the picture to look different? It is a common misconception that all electronics should exhibit the same colors, especially with devices with the same make and model. However, this is often not the case. This is illustrated with a simple experiment: when you put the same image on two monitors side-by-side, you have at least a 95% of chance that the images will not look the same, and you will probably find yourself in a situation like that shown in Figure 1. The monitors do not need to be the same make and same model, but for illustration purposes, we used four identical monitor images.                  Different colors on same kind of Devices                                                                                Figure 1: Different colors on the same type of device Another place to witness this phenomenon is when you are shopping for a new TV. Most people go to a large electronics store and decide between the TVs on display. Then, you pick the one with the colors or image quality (or price) that you find
