The principle of seamless splicing of LCD splicing screens

LCD splicing screens are divided into optical seamless LCD splicing screens and electronic seamless LCD splicing screens. The realization principle of the optical seamless LCD splicing screen is to install a special optical glass panel body on an ordinary 3.5mm panel, and realize the principle of line-of-sight refraction through the glass, so that the originally split screen can be seen in an image through the optical glass , The seams with black edges are completely invisible, and the display effect of the picture is real. The realization principle of seamless LCD splicing screen electronics is that by installing a special electronic bar on each panel unit, the electronic bar emits light equivalent to LED, and the light is emitted by two electronic bars between the seams, which can be displayed on the display. Achieve seamless seams. The seamless LCD panel joining technology has reached an unprecedented level, realizing the arrival of the era of true seamless joining technology. The seamless LCD panel joining technology is used in the high-end display field. It can be said that the visual impact it brings is also unprecedented. The seam adopts full-screen active LED electronic pixel compensation display, and the optical lens and optical refraction principle are seamless. The pixel pitch of LED electronic pixel correction is 1.5mm or less. The electronic pixel compensation LED adopts SMD label technology and does not use large particle lamp-like display. After LED electronic pixel correction, the edge of the condenser lens with high transmittance is added to

LCD splicing screen is often damaged by dust

At present, LCD splicing screens are becoming more and more mature in application industries such as indoor high-end command and control centers, dispatch centers, and monitoring centers. We all know that dust is harmful to the human body, but you certainly did not expect that dust will also do the same to LCD splicing screens. As an electronic product with extremely high technological content, LCD splicing has a great impact on it due to dust. The LCD splicing screen movement uses many optical components, and it is precisely the dust that damages the optical components the most. Contrast refers to the maximum brightness value that the large screen display unit can output divided by the darkest brightness value. When in a dark scene, the dust on the optical components will reflect stray light and project the light that should not be projected from the lens. The brightness of the dark part. Similarly, some light in the bright part will be blocked by dust, reducing the amount of light reflection and transmission, and reducing the brightness value of the bright part, the contrast will naturally decrease in the past. The color wheel of the LCD splicing screen is the main accessory for color processing, including a high-speed motor, which rotates at about 7200 revolutions per minute. If a lot of dust is attached to the periphery of the color wheel, it will affect the rolling of the color wheel, resulting in a decrease or instability of the color wheel speed, which

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
