OUTDOOR FIXED LED SCREEN1024*768MM
High-efficiency and energy-saving - LED lamps with high-grade chip package, low gray and high brightness, fully guarantee the service life and display quality of the display screen;
Adopt low-turnover voltage constant current driver IC,Improve the power loss of the IC, and then achieve the effect of energy saving; adopt AC fans with large exhaust air volume, and rationally arrange components to improve the uniformity of heat dissipation; use 3.8V and 2.8V power supplies
Separate power supply to reduce excess voltage drop by 30%, the system sets the automatic brightness adjustment function, the screen brightness can be automatically adjusted according to the ambient brightness, dynamic energy saving;
A variety of options - a variety of module sizes and spacing are flexible, and the upgrade is more considerate;
High contrast - standard 1920-3840Hz refresh rate, the video picture is more delicate and smooth; 9000:1 high contrast ratio, improve the contrast between light and dark, enhance the picture details, restore the true color;
Rainproof and waterproof - waterproof standard IP65: the module should be filled with glue, the front should also be coated with glue, and a waterproof box should be made, and the connection between the module and the box should be made of a waterproof rubber ring;
Wind resistance and earthquake resistance - in order to prevent the equipment from falling during use, there are strict requirements for the selection of wind resistance and earthquake resistance of the load-bearing steel structure;
High temperature resistance - macro ventilation design is adopted on the outside, high-density and high-precision circuit boards, try not to add fans to reduce circuit compliance;
Prevent open flames - LED outdoor full-color display uses flame-retardant materials to prevent wire aging and fire when short-circuited;
Installation method - including wall-mounted installation, embedded installation, hoisting, roof base installation, column installation, etc.;
Wide range of applications - widely used in commercial real estate, shopping malls, large squares, outdoor advertising screens, traffic screens and other fields.

| Q: What is the brightness, viewing angle and wavelength of the LED? |
| A: Luminous Intensity is equal to the amount of luminous flux emitted into a very small solid angle at a defined angular orientation from the light source. The measurement for luminous intensity is the candela. Symbol is Iv.Viewing Angle is the total cone angle in degrees encompassing the central, high luminous intensity portion of the LED beam from the on-axis peak to the off-axis point where the LED intensity is 50% of the on-axis intensity. This off-axis point is known as theta one-half ( 1/2). Two times 1/2 is the LEDs’ full viewing angle; however, light is visible beyond the1/2 point.Wavelength is the distance between two points of corresponding phase and is equal to waveform velocity divided by frequency. It defines what color human eyes could recognize |
| Q: What is dominant wavelength? Please specify the ranges of wavelength in red, green and blue color respectively. |
| A: Dominant wavelength is defined as the best range of wavelength showing the most natural color recognized by human eyes. Researches indicate that fixed colors with wavelength of 620-630nm (red), 520-530nm (green) and 460-470nm (blue), in fact mixed in a particular proportion, can get the pure white. That is, in display field, people use luminous materials with above wavelength to make “compounded” white more natural.In order to get a good balance white led display, we specify the led colors with wavelength within 4nm for each color |
| Q: Which chip vendors are you buying from? |
| A: It depends on the Customer’s requirement. We can purchase from Japan, Korea, Europe, USA. We are using chips mainly from Taiwan |
| Q: What is the chip size you’re using for outdoor display? How about indoor display? |
| A: For outdoor display, we’re using 12mil chip for red, 14mil for both green and blue. Regarding indoor display, 9mil for red, 12mil for green and blue are currently adopted |
| Q: How much will the brightness of LED drop down after 1000hrs? |
| A: Based on the result of aging test, the brightness decay of green LED is around 5%-8%, while blue is around 10%-14% and red is around 5%-8% |
