hp 42 digital signage display

Everyone is very familiar with LCD TVs, but many people don’t understand digital signage products. In fact, when we go to a hotel or shopping mall, we often see this product in the lobby, which often displays the advertising content of the hotel or shopping mall. Most people think that this is an ordinary LCD TV, but the size is a bit larger, so is this really the case? Is a digital signage a liquid crystal display? In fact, digital signage is not that simple, and there are still many scenarios in which digital signage is currently used. In addition to the hotels we are talking about, many retail industries have also begun to use digital signage products. For example, the fast food restaurants we often go to have used light boxes behind the ordering counters to display their dishes. Now many stores have also upgraded to digital signage products. In simple terms, digital signage is actually a numerical display system used in the commercial field. 1. Digital signage is usually equipped with a system Here is the system, in fact, this is the biggest difference between digital signage and liquid crystal display. We all know that the LCD monitor itself is only responsible for the function of screen output. The most important role of digital signage is actually the system behind it. Different from ordinary intelligent LCD, the digital signage system has the function of remote management. Users can design the display content by themselves, or download the template

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.

When consumers choose a projector, they usually encounter two keywords, LCD and DLP. What are the LCD and DLP seamless splicing screen projection technologies of the projector and what are the differences? Please see below. With the development of science and technology, projection technology has gradually entered the era of digital technology from LCD technology. Nowadays, the application of projectors has spread to all walks of life and came into being. There are also various brands in the technology market. For users who want to choose products, there is only one old saying: choose only the right ones, not the ones Dear. What are the LCD and DLP seamless splicing screen projection technologies of the projector? Here, I only use my personal understanding of the two major technologies of the projector to make some comments on the adaptation direction of the two types of technical products, so as to facilitate the majority of users to consider when choosing products. Liquid crystal technology is famous for its bright colors, lifelike images, high number of colors, and rich image levels. Suitable for multimedia, film and television, advertising and other industries. The disadvantage is that the light source loss is large, and the background color of the screen cannot achieve a pure white effect; after long-term use, the LCD panel is easy to age, the color is easy to attenuate, the imaging unit is larger, and the heat dissipation requirements are high. Therefore, the appearance of the LCD technology projector is general The
