How Does An LCD Screen Work? Answering A Liquid Crystal Display Tech Question #LCD #Tech   You can find Liquid Crystal Display (LCD) technology everywhere: in TVs, computers, tablets, laptops, smartphones, watches, monitors, displays, calculators, cellphones, smartwatches, and many more… but do you know how this awesome tech works? Do you also know that the working principle of LCD is pretty similar to the newer LED backlit based screens (edge LED or direct LED)? So today, we explain how an LCD screen work by looking inside an LCD screen and detailing all of its layers. We will talk about the reflector sheet, the Light Guide Plate (LGP), the Dual Brightness Enhancement Film (DBEF), the diffuser sheet, the prism sheet, the bottom polarizer, the bottom glass substrate (backplane), the Thin Film Transistor (TFT), the Liquid Crystal, the Common electrode, the color filter (RGB), the top glass substrate, the top polarizer, and the top chassis and frame. Understanding how a screen works can be especially handy to know if you like clever technology or to understand if your screen breaks down, and you need to figure out what is going on to repair it… knowledge is power!

What is the reason why mainstream DLP seamless splicing screen companies have spared no effort to invest in cross-border? Looking at the development of the entire large-screen splicing industry, the cross-border layout is a choice that relevant companies have to make. The only difference lies in where the company will focus its efforts. In the past large-screen splicing field, DLP seamless splicing large-screen large screens are the well-deserved leader. Moreover, due to the high technical threshold of the industry and the limited number of enterprises engaged, it has been able to maintain a high profit margin. With the high-end development of LCD splicing and the rise of small-pitch LED screens, DLP seamless splicing screens are no longer unique from the application market level, and are squeezed due to inherent technical defects. Subsequently, in order to maintain the established operating profit, although DLP seamless splicing screen companies actively involved in liquid crystal display and small pitch, they have lost their original monopoly advantage. Obviously, this development model is not the traditional DLP without Sewing splicing screen companies want. In the face of a rapidly changing market, if DLP seamless splicing screen companies want to maintain their leading business model, break the inherent business circle, and find a new point of force, it has become the most effective means. From a long-term development perspective, from a single operation to a diversified operation, the corporate interests of DLP seamless splicing screens will be more guaranteed, but for the DLP seamless splicing screen industry

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
