    In recent years, with the mature of the LCD splicing screen industry technology, production equipment transparent factors such as the spread of technology, such as more manufacturers involved in the production and sales of LCD screen, the product quality is uneven. A LCD screen at the same time because of the circulation in the rental market have different degree of the old and new, different technology and quality, causes such as the disordered competition performances of liquid crystal splicing screen to play the phenomenon of frequent accidents, the light will influence show effect, or will affect the program completion, led to record, etc., appeared in the process of the encounter live broadcast accident will produce serious consequences incalculable, how to reduce or avoid the liquid crystal splicing screen play accident has become the industry must pay attention to the problem.       For leasing demanders, try to choose the industry credibility good strong suppliers Supplier strength to a certain extent determines the joining together the quality of the screen, at the same time, the supplier of strength has more professional technical force and rich experience, at the same time, equipment maintenance and operation ability is stronger. Screen choose according to actual demand, need not too much pursuit, is often used for a period of time the screen has a better stability and performance.         LCD splicing screen to the maintenance of the test     LCD splicing screen should be regular overhaul maintenance equipment, check the quality of cables, frequent disassembling transportation leasing industry, should be regularly check the quality of connectors, tighten bolts, such as the connection parts, wire test regularly, prevent insulation breakdown, solder joints, even loose, etc. Conditional should periodically check switch power supply, power supply for power testing and detection of ripple caused by power failure problem is relatively common and difficult to determine. Finally to reaffirm security problem, the screen operation, in the face of high altitude, heavy current, a lot of security problems, such as wind load work must pay attention to wear safety protection device, pay attention to the operation safety, weight big screen at the same time, the area is large, large wind resistance, construction must pay attention to the foundation is solid, back shelf stability, weight is reasonable.       DDW thought in the modern performance, big splice screen with flexible expression, bearing the advantages of large amount of information occupies more and more important position in the performances. LCD splicing screen at the stage of the proportion of more and more, from atmosphere rendering performance content and gradually expand to the scene with the cast, the main visual, VCR, and even play some shows important cooperation and rendering. So literally LCD splicing screen has become a vital part of the performance now. As a result, the quality of the LCD splicing screen is undoubtedly the most concern is also the most important link.    

    As the LCD splicing screen slowly spread, diversified development, the size of the LCD splicing have appeared in the current common size 40, 46, 55, 60, such as size, which is the most commonly used size. Scale among them, these are some splicing model, and according to the technology development, there have been some big size of the monomer, for example, the emperor of emperor ai electronic launch monomer, 70, 82 inches, are more widely used.     The diversity of product size can better satisfy the diverse application environments, convenient for customer choice, also is more advantageous to the LCD splicing industry development. At the same time, the diversification of product size also means that the rapid development of industry, means that the industry have more capital and technology, continues to perfect the product line. With the diversification of products, narrower flat-fell seam, LED back light, high brightness for development and application of new technology, such as product will be more mature; Finally, the diversification of product size, impact for liquid crystal Mosaic products high-end market, share control with traditional display DLP products market laid a solid foundation, also to meet the emerging markets such as security, commercial display.     In the size of commonly used, is the use of 40 and 60 inches most hot, this two size is quite promising in future development, as the industry application of refinement, display manufacturers start from single product provider gradually integrated strong solution provider to the transformation. Excuse me, in the future market development, the role positioning of liquid crystal Mosaic manufacturer will happen, whether will be the stronger, the strong and the weak to survive? With integrated solutions ahead of the competition ability of enterprise. With the application of refinement, the customer's requirements is no longer a general product solutions, more incline to combine business efficiency improvement and function realization of application solutions, so that the business level, different growing industries.     LCD splicing diversified product size of driving the development of the LCD splicing screen market, and with the emergence of this size diversity, manufacturers began to sew products, ultra narrow edge design, liquid crystal splicing product flexibility, makes the market more and more hot. DDW is specialized in the supply of liquid crystal splicing screen products businesses, both in size and very mature technology. At the same time, the size of the LCD splicing of diversified development also brings to the DDW unlimited space for development.    

The elevator LCD advertising machine in our daily life not only to the elevator, such as numerous stores also often see some people, like this and there are many advertising machine, such as open hole 3 d display advertising machine is often seen in an elevator. Come let us know about the elevator LCD advertising machine performance advantages. The elevator LCD advertising machine performance advantage mainly include the following: First, the Angle of 175 degrees, offer you the perfect visual effect View Angle is one of the main project is the elevator floor indicator. Although we can watch the CRT display the rendered images from any Angle, but the elevator floor display (LED) must be from the front view to get the best visual effects. If from other point of view, the brightness of the screen will darken decreased (brightness), color change, and even some products will be as negative as. Second, professional industrial control host, more stable performance Elevator multimedia research and development of elevator multimedia specialized industrial control host, adopted the "embedded system" "structure without fan" "chassis cooling" "SSD" "box" "plate", etc. The application of new technologies, new products, to adapt the automation products "downsizing" the trend of the development of "intelligent" "low power", has greatly improved the industrial control system stability, and reducing the costs of manufacturing and application. Third, super wide Angle of view, any direction can enjoy the clear picture The elevator floor indicator, using the latest technology to enlarge the picture viewing angles. As a result, the best effect of elevator floor indicator, the viewing Angle have been able to approach the CRT display, was about 87.5 degrees, left and right sides of the horizontal viewing Angle of 175 degrees, can almost see the contents of the images from any Angle. In general, from 140 to 160 degree viewing Angle becomes big size elevator floors absorb the basic indicators of monitor. For smaller size 15 inches or 15 inches below the elevator floor indicator, the viewing Angle of 120 degrees is enough to show the complete picture. Left and right sides of the viewing angles are generally greater than viewing Angle, up and down is the vertical viewing Angle is less than the horizontal viewing angles (generally between 120 to 140 degrees). Fourth, the signal acquisition boards, specially designed for elevator multimedia function more powerful. Elevator multimedia real-time display all kinds of running state (up and down the floor display, overload, fire control and maintenance, the driver and other signals, can be used according to demand of customers access to access the source), to replace the original LED display screen. The elevator signal wiring access support parallel, serial, the CAN protocol interface, etc. (CAN be customized according to user requirements). If customer cannot provide protocol interface, you can use our developed by the elevator signal acquisition boards, fluctuation floor display, the overload of the elevator, fire control and maintenance, the driver and other signals, can be used according to demand of customers can access access to the source. When the elevator in the absence of hall signal after a few minutes (can be customized according to user requirements), TDD elevator has signal automatically disappear, only keep floors signal, when someone called ladder, TDD elevator has signal will automatically appear, consistent with the agreement of the lift signal; Of course, especially won't appear when the elevator is on the second floor hasn't been down to the ground floor, downward direction arrow direction is upward arrow. Wiring is simple, stable signal, consistent with absolute agreement interface signals.
