LCD mainly includes TFT, UFB, TFD, STN and other types of LCD. The structure of LCD is to place liquid crystal in two parallel glasses. There are many vertical and horizontal small wires between the two glasses. The direction of rod crystal molecules is controlled by power on, and the light is refracted to produce a picture.   High brightness, The higher the brightness value of the array LCD, the brighter the picture will be without blurring. Advanced display can display clearer and higher brightness product features. We rely on polarization filters and light itself. With the practice of natural light in all corners of the world, a series of liquid crystal filters must be parallel.   The higher the contrast, the more colorful and saturated the color will be, and the higher the plane will be. On the contrary, the color change is low, the color display is poor, the image will be flattened, and the color change value is different, even higher. Compared with CRT imager, LCD dot matrix LCD display has the advantages of zero radiation, low power consumption, small heat dissipation, small volume, accurate image recovery and high character visualization.   The view of “big view” simply means that the view in front of the screen can be seen the larger the sight distance, the easier it will be; As long as the viewer changes the viewing position slightly, the picture may become blurred.

In daily life, we must keep the habit of “cleaning” the LCD advertising machine regularly. You can spray it on the LCD advertising machine screen with a special potion, and then gently wipe it with a clean white cloth. Try not to use a damp cloth with too much water content. Too much water content on the damp cloth can easily cause water to stay on the screen. Water entering the screen through the edge can cause a short circuit in the system and the LCD advertising machine cannot work normally. It is recommended to use soft scrubbing materials such as glasses cloth and lens paper to scrub the screen to avoid unnecessary scratches on the LCD advertising machine screen. The working environment of the LCD advertising machine directly affects the operation and service life of the LCD advertising machine. If the working environment of the LCD advertising machine is too bright, or even direct sunlight, this will not only affect the visual communication of the LCD advertising machine, but also damage the LCD advertising Machine screen electronic components. The air humidity of the working environment where the LCD advertising machine is located must be kept suitable, and two extremes must not be taken. Once the electronic equipment is too humid, it will only affect the circuit conditions and cause the LCD advertising machine to fail to work normally. No matter how good electronic products are, they will have their own longest operating time, and LCD advertising machines are no

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
