The characteristics of LED display
1, High brightness: Outdoor LED display brightness is greater than 8000mcd/m2, is currently only-can be used in outdoor all-weather large display terminals; the brightness of indoor LED display is greater than 2000md/m2.
2, Long life: Led life expectancy of up to 100,000 hours (10 years) above, this parameter generally refers to the design life, brightness of the Dark is also counted;
3. Big view: Indoor view can be greater than 160 degrees, LED Panel outdoor angle can be greater than 120 degrees. The size of the angle depends on the shape of the LED light-emitting diode.
4, screen area can be small, small to less than a square meter, LED Panel large can reach hundreds of, thousands of square meters;
5, easy and computer interface, support software rich.
LED Display technology features:
1, the Effect of excellence: the use of dynamic scanning technology, the picture is stable, no miscellaneous points, the image effect is clear, animation effect is vivid, various;
2, Rich content: can display text, graphics, images, animation, video information;
3, Flexible mode: The user can be arbitrarily arranged display mode;
4, Quality assurance: The use of imported light-emitting materials, high-quality IC chips, noise-free high-power power supply
5, large amount of information: the display is unrestricted
LED display is an advanced digital information products, it successfully integrates computer technology, network communication technology, LED Panel image processing technology, embedded control technology, with flexible display area and resolution (modular can be arbitrarily assembled), high-brightness, Low-power, Long-life, low heat, environmental durability and other advantages, integrated use of sound, light, electricity, graphics, text, is a comprehensive, perfect display of information terminal products.
LED displays are being used more and more in TV studios and large-scale events on television, as a stage background, it provides a variety of vivid, LED Panel gorgeous background screen and more interactive functions, so that the background screen also static, so that the performance and background into one, people have immersive feeling. It brings more reverie space, design a modern and visual impact of the stage, LED Panel perfect the scene and the atmosphere of the program together to achieve the other Stage art equipment is difficult to achieve the function and effect.
The fill factor of the LED display (FILLFACTOR) is also known as the brightness area ratio, that is, the luminous area of each pixel is the ratio of the physical surface area of the pixel. The LED display is arranged by discrete pixels, and there is an obvious black area between pixels. When the close-up view, the screen is not coherent incomplete, and the brightness of the particles, if the source is limited to a very small pixel surface area, resulting in a single pixel brightness is the whole screen brightness of several times or even more than 10, LED Panel it will cause more serious harsh sense. Flat panel display industry recognized TCO ' 99 standard, the fill coefficient should not be less than 50%, the current market on a lot of LED display of the fill coefficient does not meet this indicator. The cut-off characteristic of the TV Low-pass filter also directly affects the suitable shooting distance of the LED display with different filling coefficients. The same point spacing of the LED display, LED Panel the filling coefficient of small than the filling coefficient of the attenuation of large, so the shooting distance needs to be increased. If the system Low-pass filter Band is 4MHz, the attenuation characteristic of high-frequency is 12db/Octave, then the shooting distance of 25% of filling coefficient is more than 50% attenuation of the filling coefficient 1.15db, the shooting distance needs to increase about 10%. The increase of the filling coefficient makes the view of the screen more broad, the color effect is more ideal, overcomes the glare of the pixel, and also improves the brightness of the whole screen to obtain the better result.
LED display with moderate and soft brightness, uniform bright color, clear and delicate expression, to ensure the high quality of the display screen.
