RGBled display

RGBLED display (RGB LED panel): R: red (red) G: green (Green) B: blue (blue) LED is light emitting diode, the acronym for light-emitting diodes, called LED. It is a semiconductor light-emitting diode by controlling the display to display text, graphics, images, animations, quotes, video, video signals and other information display screen. Graphic display and LED display into the video display, LED matrix by blocks. Graphic display can be synchronized with the computer to display Chinese characters, English text and graphics; video display using micro-computer control, graphics, images, and Mao, in real time, synchronization, clear the broadcast of a variety of information dissemination, but also shows two dimensional, three-dimensional animation, video, TV, VCD programs, and live on. LED screen display colorful, three-dimensional sense of strong, static, such as painting, moving like the film, widely used in railway stations, wharves, airports, shopping malls, hospitals, hotels, banks, securities markets, construction market, auction houses, industrial enterprises in management and other public places. 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 the reason why the rapid development, is that it itself has the advantage inseparable. To 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, the current is moving higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability, full color direction. The classification of a LED display, color by color can be divided into single-color display: Single color (red or green). Dual-color display: red and green dual-color, 256 gray, you can display 65,536 colors. Full color display: red, green, blue color, 256 gray level display can show full color more than sixteen million kinds of colors. 2, according to display category LED digital display: 7 segment display digital code, suitable for production of the clock screen, screen, and other interest rates, display digital electronic display. LED dot matrix graphic display: display device is composed of many evenly composed of light emitting diode dot matrix display modules, suitable for broadcast text, image information. 3, by using the occasion categories indoor display: small light-emitting points, the general Φ3mm - Φ8mm, shows the general area of ​​a few to more than ten square meters. Outdoor display: the general area of ​​tens of meters to several hundred square meters, high brightness, can work in the sun, with wind, rain, water resistant. 4, classified according to the indoor light spot diameter screen: Φ3mm, Φ3.75mm, Φ5mm, Room shielding: Φ10mm, Φ12mm, Φ14mm, Φ16mm, Φ18mm, Φ20mm, Φ25mm, Φ31.25mm, Φ36mm, the basic unit of room for the external screen light emitting tube , the principle of light-emitting tube is a set of red, green, and blue light-emitting diode sealed in a plastic tube joint light enhanced brightness. led electronic display production process: a) Cleaning: ultrasonic cleaning PCB or LED support, and drying. b) mountings: The LED die (wafer) on the bottom electrode silver paste prepared after the expansion, the expansion of the die after the (wafer) placed in the thorn crystal table, under a microscope with a thorn in the crystal pen die mounted on a PCB or the LED of a corresponding pad on the support, followed by sintering the silver adhesive curing. c) pressure welding: welding with aluminum wire or gold wire electrodes connected to the LED die on the lead for current injection. LED mounted directly on the PCB, the general use of aluminum wire welding. (TOP-LED need to make white gold wire welder) d) Packaging: By dispensing with epoxy to protect the LED die and wire up. Dispensing in the PCB board, the shape of the cured gel, there are strict requirements, which is directly related to the backlight brightness of the finished product. This process will also assume the point of phosphor (white LED) task. e) Welding: If the backlight is the use of SMD-LED, or other encapsulated LED, in the assembly process, you need to LED soldered to the PCB board. f) cutting film: punch die with all the necessary backlight diffusion film, reflective film. g) Assembly: According to the drawings, a variety of materials to backlight manually install the correct location. h) Test: Check out the backlight optical parameters and light uniformity is good.
