♦ 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.
