digital signage requirements

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

As a new type of identification product, digital signage has some personalized functions that traditional signs do not have. It is precisely because of these distinctive functions that it can occupy a place in the market, and now digital signage has embarked on The fast lane of rapid development. So, have we found that in different scenarios, the role and function of digital signage are different, and the way of interaction is also different. The root cause of this problem is that user needs are different, so it is necessary to customize functions according to user needs Development, now the problem is coming again. From the current digital signage on the market, what are the common functions of digital signage? Below we expand from three aspects; 1. Queuing for number collection. This function is actually a more traditional function, and it is also a function that we have more contact with. For example, when we go to public places to do business, due to the large number of people, we need to give each user a number, according to the number The order of work is done in order, so that the order is easy to maintain, and the work efficiency is high. To solve this user’s pain point, the function of digital signage self-checking is not suitable. In addition, there are some file-like materials that can also be self-printed through digital signage. In fact, many self-service terminals can be counted as digital signage.   2. Guides and guides. In

We will use some electronic devices in our life, LCD module is one of the electronic components. Everyone’s understanding of it must be relatively strange, and then we will talk about the knowledge in this respect.   The following is an introduction to the three basic components and features of LCD. Let’s take a look with the editor: Liquid Crystal Materials Liquid crystal material is the main body of liquid crystal display. Different devices use different liquid crystal materials. Most liquid crystal materials are composed of several or even more than ten kinds of single liquid crystal materials.   Polarizer The light sheet, also known as polarized light, is made of plastic film material, coated with a layer of optical pressure sensitive adhesive, which can be pasted on the surface of the liquid crystal cell. There is a protective film on the surface of the front polarizer, which should be removed when using. The polarizer is afraid of high temperature and high humidity, which will depolarize or blister under high temperature or high humidity conditions.   Glass Substrate A kind of float production thin glass sheet with extremely flat surface, the surface of which is evaporated with a layer of zn203 or sn02 transparent conductive layer, i.e. ITO film, is processed into transparent conductive pattern. If scratched, cut or corroded, the vacuum device will be scrapped.
