FEATURES

♦ Long lifetime: Adopting high quality LED lamps as core material and patent PCB design for the screen, it essentially ensures long lifetime fo the product.

♦Wide view angle: Highly wavelength consistency of LED lamp and 120°horizontal and vertical view angles guarantee viewers can see the playing miages from any direction in front.

♦ Stable performanve: we make a spceial treatment of anti-electromagnetic wave and adopt distribution scan and modular design for the screen and it works more reliable and stables.

♦ Exquisite images:Nonlinearity correction technology makes the images exquisite clear, video images vivid and fidelity.

♦ Excellent flatness: percision design of module frame parts controls the deviation of beighbouring modules within 0.1mm and it has an excellent flatness without mosaic..

♦ High contrast:consistend deep black patent masks and black face lamps make the contrast higher and the color fresher.

♦ Live broadcast: It can support DVI,HDMI, 3G/HD/SC with SDI high definition display mode, suit for TV programes VCDprogrames, DVDprogrames and live broadcasting indoor .

♦ Easy installation: Modular design makes the installation and maintance easier.

♦ Good material:Adopting same levels of imported LED chips from taiwan, USA or Japan, high quality driving IC, low nosie power supply, which can guarantee the screen works mooth in the environment of -20 degree to 40degree.

♦ Multiple formarts :Customers can choose any one of display formats for the screen, it can supports TXT, graphoc, picture animation and video programe.

♦ Lacquer coating: Lacquer coasting can protect the PCB and relevant components from erosion of environment, it has the good resistance performance of low and high temperature, and excellent features of insulation, moisture proof, anti-creeping ,dustprrof,anti-corrosin.

♦ High shockproof performance: The cabinets must be tested for shockprrof performance before shipment to avoid poor contact because of loose of screws and disconnection of cables after ling line -haul.

Q: Ask to tell, or what decoder, mkv format can only put one, the rest of the mkv can not put any meaning?: a graphic editing, zoom, scroll, animation and other functions can display a variety of computer information, graphics, images and Two, three-dimensional computer animation, can be superimposed text ? broadcast system with multimedia software, you can flexibly enter and broadcast a variety of information ? a variety of Chinese fonts and fonts to choose from, but also enter the English, Spanish, French , German, Greek, Russian, Japanese and other languages ? There are a variety of ways to broadcast,

Q: Is the TV screen good for the LCD or the LCD?: Whether it is LED TV or LCD TV, their screen itself is LCD (LCD), the real LED display is difficult to use in the field of home TV, because its pixel is too large, high-resolution case is difficult The Now many of the store's dynamic billboard is LED dot matrix screen.

Q: 16: 9LED What is the approximate size of the display?: First determine a length or width size, here to length as an example. If the length is 96 meters, then 96 ÷ 16 = 6 × 9 = 54 meters

Q: Led display and led lighting What is the difference?: LED display and lighting are LED light-emitting diodes as light source. The difference is that the application of LED: LED display using dot matrix, the combination of different colors of light-emitting diodes, through the control system, power system, signal system and other forms of control, composed of LED device array display screen; and LED Lighting is a monochrome diode excitation, the pursuit of brightness, gray and white balance.

Q: Production of LED display the basic raw materials which ah?: PCB, circuit board, drive IC, resistance, exclusion, LED light-emitting diodes, row of pins, row seats, capacitors, three anti-paint, plastic sets of plastic, waterproof plastic, fine screws, copper pillars, magnets, Power cord, connector, switching power supply, frame. Control System.

Q: LED display how to install it?: 1) single column installation: for small screen applications; 2) double column installation: suitable for large-screen applications; 3) closed maintenance channel: applicable to the use of the following columns: 1) single column installation: In the simple box; 4) open maintenance channel: for the standard box.

Q: LED display power supply how to configure how many units with the plate is calculated.: I with 14 P10, power supply * (0.8-0.9) / each unit board power can be rounded down.

Q: LED electronic display and P have anything to do: The above-mentioned P4 indicates that the dot pitch is 4mm and P10 indicates that the pixel distance is 10mm. In addition, the best visual distance = point spacing / (0.3 ~ 0.8), for example, the dot pitch 16mm display, the best visual distance on this is 20 to 54 meters, the distance from the station closer to the nearest distance , And will be able to distinguish one of the pixels of the display, grainy stronger, stand far away, the human eye can not tell the details of the details.

Q: LED display applications are what: Securities trading, financial information, airport flight dynamic information display, port, station passengers, sports venues information display, road traffic information display, dispatch command center information display.

Q: Led display speed how to tune: When installing the LED bar screen software, enter the text that needs to be displayed in the blue edit box. After the text editing is finished, click "Frame Properties" to pop up the following dialog box to set the frame properties. Display speed 1 fastest, 16 slowest. After setting the current frame, you can point to "previous frame" or "next frame" to move to another frame. After all the parameters of the frame are set, click the "Exit" button to return to the main window.
