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 difference between touch all-in-one and ordinary touchpad

In fact, until now, many people still confuse the touch all-in-one with an ordinary touchpad, and think that as long as the touchable screen is a touch all-in-one, this understanding is wrong. Bank ATM teller machines and traditional supermarket cash registers that we see every day belong to traditional touch panels instead of touch all-in-ones. Traditional touch panels are generally single-point or double-point touch, and touch all-in-ones are actually It can realize infrared or capacitive multi-touch. We will talk about the advantages and disadvantages of infrared touch and capacitive touch and their application fields next. What is the difference between a touch all-in-one machine and an ordinary touchpad, you must know Capacitive touch screens are currently mainly used for the display of high-end devices such as mobile phones, tablets, and computers. The touch function can be realized with the skin of a human finger, multi-point, handwriting, etc. can be realized without any problem. Capacitive touch screens cannot be touched with gloves, and there is no response to touch with gloves, and the larger the size of the product required, the more expensive it is. The capacitive screen all-in-one machine is more beautiful, more beautiful, lighter and thinner, pure flat surface, and easy to realize. With waterproof function, the reaction speed is more sensitive at the same time. Infrared touch screens are currently not used for the display of high-end devices such as mobile phones, tablets, and computers. The infrared touch screen is currently only for the display. The infrared touch

Digital Signage Daily maintenance

1. Keep the humidity in the environment where the digital signage is used, and don’t let anything with damp properties enter your digital signage. Powering on digital signage that contains moisture will cause corrosion of the digital signage components and cause permanent damage. 2. To avoid problems that may be encountered, we can choose passive protection and active protection, try to keep the items that may cause damage to the digital signage away from the screen, and when cleaning the screen, wipe it as gently as possible to reduce the possibility of injury Minimize. 3. The relationship between digital signage and our users is the closest, and it is very necessary to do a good job in cleaning and maintenance. After being exposed to wind, sun, dust, etc. in an outdoor environment for a long time, there will definitely be a piece of dust on the screen after a period of time. This needs to be cleaned in time to prevent dust from covering the surface for a long time to affect the viewing effect. 4. It is required that the power supply is stable and the grounding protection is good. Do not use it under severe natural conditions, especially strong thunder and lightning. 5. It is strictly forbidden to enter the screen body such as water, iron powder and other easily conductive metal objects. Digital signage should be placed in a low-dust environment as much as possible. A large amount of dust will affect the display effect, and too
