LED display can show changes in the numbers, text, graphics and video; not only the indoor environment can also be used for outdoor environment, with a projector, TV wall, LCD screen can not match advantage. LED widespread attention and rapid development, and it itself has the advantage inseparable. They sum up these advantages are: high brightness, low voltage, low power consumption, small size, long life, impact resistance and stable performance. LED is extremely broad prospects for development, incumbents Shanghai Fortunately, Ma Electronics as an industry leader in the early development of the industry plays a key role. For now, LED is moving higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability, full color direction. A, LED display Category: 1, depending on the color classification of single color display: a single red or one green; color display: red and green dual-color, 256 gray scale, you can display 65,536 colors; full color display: red, green, blue color, 256 grayscale full color display can display over 16 million colors. 2. The composition of the pixel unit Category Digital Display: 7-segment display pixels, suitable for production of the clock screen, screen, and other interest rates; graphic display: pixel dot matrix display modules, suitable for broadcast text, image information; video Display: display pixel by a number of light-emitting diodes that can display video, animation and other video files. 3. The use of position classification in the indoor display: luminous dots, dense pixel pitch for a closer look; semi-outdoor display: between indoors and outdoors, no protection against rain, suitable lintel guidance and other information for use ; outdoor display: light-emitting point and the pixel pitch, high brightness, can work in the sun, with wind, rain, water resistant, suitable for long distance viewing. 4, according to drive a static, horizontal scrolling, vertical scrolling and page display. Second, the display with LED display types, advantages and disadvantages according to the classification used LED pixel can be divided into the following categories: 1, dot matrix module advantages: low cost, processing technology is mature, stable quality; Disadvantages: brightness, Color consistency is not good control, prone to Masai Ge phenomenon; 2, line lights advantage: better color consistency control, pixel pitch size can be adjusted freely combined as required; Disadvantages: poor RGB color mixing effect, angular Big, bad control the angle of consistency, the process is prone to uneven, up and down easily misplaced; 3, SMD advantages: Color, color mixing effect, consistency is the best angle; Disadvantages: packaging, processing, high costs; ‖ three display with LED packaging technology requirements of different applications using different specifications location display, depending on the screen and require different technical requirements of LED devices, then display with LED What are the technical requirements for it in the end, the following According to different classification described one by one: 1, indoor display with SMD LED indoor display with SMD LED is divided into "three and one" and "triple play", where the former are used for relatively low-cost, show less demanding areas, which showed better results, the cost is relatively high, the following principal on the "triple play" to do some explanation; 1, Brightness: first thing to consider is the product match the brightness of the appropriate scale, the current large Most full-color display of red, green and blue are in accordance with the brightness of the match 3: 6: 1 (that is, inside a red pixel brightness 30%, 60% green, 10% blue) ratio; and general packaging plant almost all of the upstream chip manufacturers to test products according to 20mA, but really applied to the display, almost none of the current drive LED lights, red, green and blue LED in general is not the same because the constitution of the wafer material, they are in actual use of heat, light, light attenuation is also disproportionate, generally speaking a number of red attenuation ratio, cyan attenuation, and therefore in order to ensure that the display is relatively long service life, the designer would generally The blue, green and red is lower than some of the driving current; for example: if the red driver according 18mA, 15mA drive green, blue 12mA drive LED wafer according to IV-If relationship: We generally can be calculated, the actual needs of the LED brightness, RGB relationship is: R: 3 ÷ 90% G: 6 ÷ 75% B: 1 ÷ 60% but also the brightness binning, binning purpose is to make out of the screen do not let the naked eye can see the difference in brightness, generally more sensitive to the human eye can distinguish the difference between the brightness of 30%, net equipment testing error and mounting mechanism error, design splitting 10% to 20% in accordance with sub-file is good. Color outdoor advertising LED screen outdoor display LED outdoor electronic screen electronic display 2, Color: The optical effect, through the prism of white color after being broken down into a variety of gradual transition of chromatography, followed by the color red, orange, yellow, green, blue, blue, purple, which is the visible spectrum. In which the human eye to red, green and blue is most sensitive to the human eye as the receiver of a three-color system, most of the color can be red, green, and blue synthetically produced in accordance with different proportions. Also the vast majority of monochromatic light can be broken down into red, green and blue shade. This is the basic principle of colorimetry, namely the principle of the three primary colors. Three primary colors are independent, we can not have any kind of colors the other two color synthesis. Red, green and blue are primary colors, three colors synthesis of the most extensive range of colors. Red, green and blue primary colors according to the different blending ratio of the sum called synthetic additive mixture. RGB three colors so that they are independent, either of the same color can not be produced by mixing the other two colors. Different proportions of the three primary colors of light obtained by adding known additive color mixing. Its rule: red + green = yellow red + blue = purple blue + green = cyan red + blue + green = white display with LED best colors are: red 620-630nm, green 520-530nm, blue 465 -475nm, of course, this range can also be narrowed based on actual needs, such as red to 3nm as a file, a file for the blue-green to 2.5nm. Angle: In fact, for perspective, of course, the bigger the better, but more important is not just large enough angle, the angle of the curve needs to be full, smooth, red, green and blue to be able to coincide consistent, otherwise there will be good display After some locations may show a dark area, or a certain color extremely bright or dark; 3, electrical parameters of the electrical parameters of LED mainly in forward voltage (vf) reverse current (Ir) and antistatic ( ESD), generally used for the display are used 5v DC power supply constant current drive, so: LED's Vf generally do not require too much consistency, as long as the control in a reasonable range to (usually red 1.8-2.2v, blue-green 3.0 3.4v); ESD is generally the bigger the better, because ESD everywhere, so the larger the LED of ESD, do not display the more error-prone process; reverse current requirements Vr = 5v, Ir ≦ 10uA. color outdoor advertising LED screen outdoor display LED outdoor electronic screen electronic screen outdoor display with oval line LED outdoor display with LED line lights generally more oval structure with respect to indoor display with LED concerned, outdoor oval Light emitting angle watched mainly in the horizontal and vertical angle problem, generally display outdoors, the horizontal viewing area was relatively large, vertical visual range in relatively low; outdoor advertising screen LED outdoor color display outdoor electronic screen electronic display LED outdoor display LED general lateral angle of about 110 degrees, about 50 degrees in the longitudinal direction is good, because the angle of light line has a number of factors, mainly in: (1) LED The external shape of the package; (2) structural support cups; (3) the structure itself and the wafer; (4) the refractive index of encapsulated glue; (5) the consistency of the quality of the material; (6) packaging process (i.e., the wafer luminous height); therefore, outdoor display with LED angle more bad master, not only the need for good design, but also a better process design and quality control standards. As technology continues to improve, the display will be increasingly high demands, of course, LED packaging technology requirements will equally high demand.
