digital signage led display

With the vigorous advancement of the country’s new infrastructure during the “14th Five-Year Plan” period and the development of the contactless economy in the post-epidemic era, enterprises, governments, transportation, education, medical and other fields will accelerate intelligent and digital transformation, and smart display terminals have become an industry An indispensable basic carrier in digitization. As the application scenarios of smart commercial display become more and more extensive, its industrial value is constantly improving, and it has become an important strategically significant field in the electronic information industry. As an important part of the LED display, it is natural to not miss this blue ocean market with unlimited prospects. Two commercial display products, digital signage and LED advertising machine, have occupied most of the outdoor commercial display market share in recent years. In today’s market, digital signage is dominated by outdoor commercial display, mainly LCD, and the current LED outdoor advertising machine is also a commercial display product that has only gradually emerged in recent years. Why did digital signage come into being? LCD or LED? Along with the development trend of digital information technology, commercial offices such as merchants, enterprises, and units have already begun to switch to digital propaganda. Traditional posters, leaflets, banners, etc. have all begun to show a substantial reduction, as there are many digital devices that can replace them, and the effect is even better. In today’s day when digital information becomes normal, digital signage has come into life, and the work of publicity and display

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.

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
