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

Pixel is a kind of unit. Generally speaking, it is invisible to the naked eye. How can we see the pixels of LCD? That is, if the image of LCD is magnified several times, many small square dots will be found. These small square dots are actually the so-called pixels.   The LCD splicing unit of LCD is a full-color screen, and red, green and blue are the primary colors of colors. Because LCD has many colors to realize, it needs to combine the red, green and blue lights to form pixels.   The pixel of LCD is a unit used to calculate the digital impression. Just like the photo taken, the digital impression also has continuous tone. If you enlarge the impression several times, you will find that these continuous colors are actually composed of many small dots near the color.   In addition, the pixels of LCD include real pixel display and virtual pixel display. The two technologies are different. The virtual display adopts virtual pixel technology, that is, LCD multiplexing technology. The same LCD light-emitting tube can be combined 4 times with adjacent LCD light-emitting tubes (down, down, left, and right combinations). Generally speaking, the pixel is a unit. The pixels of the current LCD display are 1920 * 1080, and the pixels of the Department display can be as high as 3840 * 2160. The higher the pixel, and more clearer the picture will be.

Recently, the price rise trend of LCD is very obvious. Some original manufacturers have adjusted the ex-factory price many times, and some even adjusted the price more than 20% at one time “A panel factory recently raised its price twice in a row, each time adding 5 yuan to the original price. In fact, this kind of increase is not surprising in the industry”. The source said.   The cause and effect of this price increase   As for price increase, we are more concerned about price increase, duration and category. In fact, in this round of price increase, the rise of different LCD screens is not the same.   There are structural differences in the price increase. The main performance is that the price of low-end LCD products increased by 20% – 30% or even 40% – 50%.LTPS (low temperature polycrystalline silicon) screen and AMOLED (active matrix organic light emitting diode panel) used in high-end mobile phones have little or no price increase. At the same time, 32″ and 38.5″ LCD screens for small size TV sets have fallen below the cost price of materials, and manufacturers have been seeking price increases in recent months, while the price of 70″ or more LCD screens for large size TV sets has not fluctuated much. LCD agent Shenzhen weishixin Co., Ltd. Chairman Lu Naiming said.   According to reports, the last price rise cycle of LCD was from 2016 to 2017, and its overall market price has been falling since 2018.
