Some time ago, I have pushed the "Top Ten Trends in the LED Industry", which is mainly the lighting company's gameplay. In fact, display companies also have their own new gameplay! It can even be said that when lighting companies are still thinking about how to play, the display companies have already played, and played a lot of new tricks, which can be summarized as: 5 new screens, 5 new applications, 5 big New mode.
Five new screens
1 small pitch screen
Where is Hyun? The small-pitch LED display refers to the indoor LED display with LED dot spacing below P2.5, mainly including P2.5, P2.0, P1.9, P1.8, P1.6, P1.5 and other LED displays. product. The ultimate competitiveness of indoor high-density small-pitch LED displays is that the display is completely seamless and the natural color of the display color. At the same time, in the aspect of post-maintenance, there is already a mature point-by-point correction technology. With one or two years of display, the instrument can be used for one-time correction of the whole screen. The operation process is simple and the effect is good.
Where is it difficult? Subject to the constraints of packaged devices and technology. Smaller pitches are getting smaller and smaller, and they face some challenges in the process of making them, such as production processes at ultra-high temperatures. The small pitch itself is small, and the distance between the material and the material is extremely short. As long as there is a small error, many intermittent defects occur, such as easy short circuit between the wafer and the wafer.
2 wireless screen
Where is Hyun? LED wireless display is the use of GSM, GPRS, CDMA, 3G and other wireless communication networks to achieve remote, real-time and large-scale networking information release of LED display. (1) Large-scale networking: LED wireless display sends information through GSM, GPRS, CDMA, 3G and other wireless networks. TCP/IP network transmission protocol is adopted, and the number of terminal networking is not limited, so it can be networked on a large scale. (2) Post information in real time: The LED wireless display can receive the information sent by the information center at any time. (3) Unlimited distance: LED wireless display can be used nationwide, as long as there is a wireless network signal coverage, regardless of distance and location. (4) Convenient installation and maintenance: Since there is no need to lay fiber optic cable or communication cable, the installation position of LED wireless display is easy to select; modular design, easy to maintain and overhaul, and automatically save all information automatically dial-up Internet, automatic redial of dropped calls , to ensure reliable connection; anti-interference design, suitable for electromagnetic harsh environment applications; high and low temperature design, suitable for low temperature and high temperature working environment. (5) Multiple information distribution methods: According to different communication networks, different information transmission methods can be used to update the information on the LED wireless display, and the information can be sent in groups, groups, and single points. (6) Multiple information encryption methods: If the information can be sent according to the user's needs, the identification code and the check code are added, or only the special number is received. Keep information safe.
Where is it difficult? (1) The phenomenon that is common in wireless LED display enterprises is that there are many production equipments and there are few fixtures. The use of supporting fixtures can improve the reliability of products and reduce the failure rate of products. It is a device that cannot be ignored in the production process. (2) There is no top-down technical index decomposition process, the design process is insufficient, and the reliability indicator verification process is lacking. (3) Turning a blind eye to the large number of existing electronic manufacturing standards, even thinking that there is no standard specification in the wireless LED display industry. (4) Focus only on reducing manufacturing costs, regardless of the total cost of product life cycle.
3 smart screen
Where is Hyun? The LED intelligent display is actually a combination of the display and the Internet to realize cluster-type remote release, remote control and remote monitoring. The size of these clustered LED displays is dozens, hundreds, or even thousands. Piece. When there is a problem with the display, it will automatically alarm in time, then analyze its own status, and some problems can be automatically repaired, etc., to a certain extent reduce the workload of the engineer. With the development of technology, the intelligent display will be further upgraded. The smart display is not only to display high-definition, smooth, dynamic pictures and videos, but also to provide more functions and services for consumers to use and enjoy, to enhance interaction and personal experience with consumers.
Where is it difficult? It is necessary to continuously improve the intelligent functions, solve various defects in the intelligent process, and provide more intelligent services according to the needs of consumers. Cloud intelligence is the trend of development. Also guard against security issues and avoid disclosure of private information or secret information.
4 transparent screen
Where is Hyun? The transparent display can make the screen transparent like glass, maintain the transparency while ensuring the richness of the dynamic picture and the display details. Therefore, the transparent display interactive display device allows the user to view the behind-the-scenes through the screen and can Let users interact with the dynamic information of the transparent display. Ideal for malls displaying jewellery and a variety of high-end goods as well as the museum industry to display some artifacts.
Where is it difficult? Not suitable for personal use environment, it is difficult to solve problems such as privacy. The technology is not very mature, especially for some special size panels. The cost is relatively high and it is not suitable as a popular product. The supporting environment is not mature. For example, in the mobile field, batteries and other components have no way to achieve ultra-small size to meet the design of the wind.
5 shaped screen
Where is Hyun? The appearance of the special-shaped LED display breaks the rectangular shape of the large-screen splicing system, which can only be spliced ​​into a cold ice. It can be arbitrarily spliced ​​into various irregular shapes to display some creative content, which can not only attract the audience at the first time. The eyeball thus achieves a better publicity effect, and at the same time, it also better expands the application range of LED display splicing. The general classification is: three-dimensional surface (such as spherical screen, polyhedral screen and sky screen, etc.), arc shape, irregular shape, strip shape. The special shaped screens such as: LED spherical screen (LED spherical screen, triangular spherical screen, six-sided panoramic spherical screen), LED signs (assembled by special LED modules of different specifications, not limited by the size of the screen, can Flexible assembly into the text, graphics and LOGO of the customer's needs, LED human face screen (using a flexible, flexible series of LED display screens with different pitches, vividly depicting the facial features of the face), LED inner arc Screen (the display will enclose the audience 360°, the audience can stand at the center of the venue to watch, can form a 360° panoramic picture), LED DJ, LED cans.
Where is it difficult? Because the LED shaped screens have different appearances and different structures, the technical requirements of the manufacturers are also more stringent. If the manufacturer's technology is not enough, the LED screens that are spliced ​​will have many problems such as uneven layout and uneven layout, which will affect the viewing effect and undermine the aesthetics of the overall design. More importantly, the design of the circuit and structure of the LED shaped screen is complicated, and the manufacturer's R&D capability is highly demanded.
