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

Digital signage has been developed for many years, but due to various objective reasons, it has not yet been popularized on a large scale. However, in some government service establishments and high-end commercial establishments, digital signage has been widely adopted. This shows that digital signage Signage is moving forward along the logical route of commercial development, and it has not stopped, let alone its development. Based on years of experience in digital signage projects, we believe that the following three changes are initially expected in digital signage in the next three to five years: Development trend 1, response methods will be more diversified As far as the interactive mode of digital signage is concerned, the response mode is relatively simple. Basically, it is operated by the touch screen. After clicking, the digital signage will make corresponding actions according to relevant instructions, such as issuing tickets and so on. However, people’s pursuit is endless, and more needs have not been met for the time being. At this time, new solutions are often needed to solve these pain points. Therefore, will there be new ways to respond in the future? , The answer is yes, such as voice interaction, voice interaction, and interconnection with mobile phones, etc., may be the specific form of future response methods. Development trend 2, the full integration of reality and virtual We are no longer unfamiliar with the terms augmented reality (AR) and virtual reality (VR), because over the years, the development of AR and VR has
