Digital signage is a relatively advanced identification product. In recent years, we have seen more and more digital signage in reality, and the application scenarios are gradually expanding in depth. If you follow a relatively stereotyped expression, that’s it. “Digital Signage” is a brand-new media concept. It refers to public places where large shopping malls, supermarkets, hotel lobbies, restaurants, cinemas and others converge. Multimedia professional audio-visual system for financial and entertainment information.” In fact, the digital signage we currently see does stay at the basic display stage, but we can’t simply interpret the digital signage as an advertising machine, because the advertising machine is one-way The information conveying itself does not recognize the user’s behavior or instructions, and we now focus more on the intelligentization of digital signage, which is the essence of the development of digital signage. Compared with traditional display signs, one of the biggest features of digital signage is that it can interact with users. This interaction may be in a variety of ways, such as traditional mechanical buttons, touch screens, mobile phone scan codes to send related instructions, and even voice. There are also body movements, etc., which can all be used as interactive methods. In fact, we can deeply experience this in the field of science and education, especially in the robot-related interaction process, we can interact with the big screen through body movements. This is theoretically a typical development direction of digital signage. . In the initial stage, the digital signage we understand is

Improve the contrast of the LED display: Contrast is one of the key factors that affect the visual effect. Generally speaking, the higher the contrast, the clearer and more vivid the image, and the brighter and brighter the color. High contrast is very helpful for image clarity, detail performance, and gray level performance. Increase the gray level of the LED display: the gray level of the LED display refers to the brightness level that can be distinguished from the darkest to the brightest of the single primary color brightness. The higher the gray level of the LED display, the richer the color , The color is brighter; on the contrary, the display color is single and the change is simple. The increase of the gray level can greatly increase the color depth, making the display level of the image color increase geometrically. Nowadays, many LED display manufacturers can set the gray scale of the display to 14bit~16bit, so that the image level can distinguish the details and the display effect is more delicate, vivid, and colorful. Narrowing the dot pitch of the LED display: narrowing the dot pitch of the LED display can greatly improve the clarity of the display screen, because the smaller the dot pitch, the higher the pixel density per unit area of ​​the LED display, and the more details that can be displayed More, the screen display is more delicate and lifelike. The combination of LED display and video processor: The LED video processor can use

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
