digital signage week

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

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

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
