Digital signage system

Digital signage is a brand-new media concept. It generally refers to large-scale shopping malls, supermarkets, hotel lobbies, restaurants, airport subway stations, cinemas, and other public places where other people’s traffic converge. The large-screen terminal display equipment can release business information and finance. Multimedia professional audio-visual system with entertainment information. Its purpose is to broadcast advertising information to a specific group of people in a specific physical place and a specific time period, so that it has the effect of advertising. Overview The digital signage system is juxtaposed with paper media, radio, television, and the Internet, and is called the “fifth media.” composition The Digital Signage system consists of the following parts: ——Display terminal (LCD liquid crystal display) –media Player Support video: MPEG-1, MPEG-2, MPEG-4, DivX, Xvid, H.264, Quicktime, WMV, AVI, FLV Audio: MP3, WAV, AC3, AIFF Images: JPEG, GIF, PNG, TIFF, BMP, and image slideshows with page turning effects Flash animation: Flash 8, Flash 9, Flash 10 ——Management Software 1. Content management -Powerful browser interface for media content creation and management -Role-based account security control -Create new program types without programming -Each player can customize different playlists -Online preview of the designated player, the playlist of the designated time -Dynamic display content defined by XML -Support dynamic content data in RSS format 2. Advertising management -Each ad placement can include one or more media files -You can specify the number of times and the sequence of ads in each playlist -Support multiple media formats: AVI, FLV (Flash Video), Quicktime MOV,

What are the basic components of LCD?

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.

What are the pixels of LCD?

Pixel is a kind of unit. Generally speaking, it is invisible to the naked eye. How can we see the pixels of LCD? That is, if the image of LCD is magnified several times, many small square dots will be found. These small square dots are actually the so-called pixels.   The LCD splicing unit of LCD is a full-color screen, and red, green and blue are the primary colors of colors. Because LCD has many colors to realize, it needs to combine the red, green and blue lights to form pixels.   The pixel of LCD is a unit used to calculate the digital impression. Just like the photo taken, the digital impression also has continuous tone. If you enlarge the impression several times, you will find that these continuous colors are actually composed of many small dots near the color.   In addition, the pixels of LCD include real pixel display and virtual pixel display. The two technologies are different. The virtual display adopts virtual pixel technology, that is, LCD multiplexing technology. The same LCD light-emitting tube can be combined 4 times with adjacent LCD light-emitting tubes (down, down, left, and right combinations). Generally speaking, the pixel is a unit. The pixels of the current LCD display are 1920 * 1080, and the pixels of the Department display can be as high as 3840 * 2160. The higher the pixel, and more clearer the picture will be.
