Full-color LED display is the LED display one of full color at the same time, also known as the three primary colors: a minimum real unit composed of red, green, and blue composed of 256 full-color gray-scale LED display can show more than sixteen million kinds of colors. led full color using red, green and blue light-emitting tube, each tube each 256 gray constitute 16,777,216 colors. Contents 1 Introduction 2 Expand Full Color LED Display 2.1 full color LED display several elements: 2.2 full-color LED display angle consistency: 2.3 full-color LED display dedicated LED selection: 3 full-color LED display applications Full Profile color LED display full-color LED display full color LED display is a LED display, full-color at the same time, also known as the three primary colors: a minimum real unit composed of red, green, and blue composition, 256 gray full-color LED display can show more than sixteen million kinds of colors. led full color using red, green and blue light-emitting tube, each tube each 256 gray constitute the one thousand Shi Qi Qi Lu Bai Lu Wan Qi Qian Erbai one hundred colors. Full-color LED display full color LED display several elements: 1, loss of efficiency due to the full-color LED display by a group of thousands or even hundreds of thousands of red, green, and blue LED pixels composed of dots, any color LED The failure of the display will affect the overall visual effect. In general, according to industry experience in LED display will begin to assemble the failure rate of aging 72 hours before shipment should not exceed ten thousandths (of a failure of the LED device itself causes). 2, the antistatic ability LED is a semiconductor device, sensitive to static electricity, caused by static electricity can easily fail, it is essential to monitor the life of antistatic ability. Generally speaking, LED's body static mode test failure voltage of not less than 2000V. 3, the attenuation characteristics of red, green and blue LED display have with increasing working time and attenuation characteristics. LED display chip's strengths and weaknesses, the quality and level of packaging technology auxiliary material determines the LED decay rate. Typically, 1000 hours, 20 mA at room temperature after the lighting test, the red LED attenuation should be less than 10 [%], blue, green LED attenuation should be less than 15 [%]. Red, green, and blue attenuation consistency full-color LED display great influence in the future, and thus influence the display of display fidelity. 4 LED display manufacturer, brightness LED display brightness is an important determinant of the display's brightness. LED display brightness, the greater use of current margin of power savings, keeping LED stable good. LED has a different angle, the brightness has been set in the chip case, the smaller the angle, LED display is the brighter, but the perspective of the smaller screen. General should be chosen to ensure that the 100-degree LED display sufficient perspective. Different for different point spacing and line of sight of the display, you should find a balance in brightness, angle and prices. Full-color LED display angle consistency: full-color LED display is composed of numerous pixels of red, green and blue LED composed spell, the brightness of each color LED, the wavelength of consistency determines the entire LED display brightness consistency, white balance consistency, color consistency. Generally, led display manufacturers requires suppliers to provide components and 1 5nm wavelength range: the range of 1.3 brightness LED, these indicators can be component suppliers were graded by color separation machine reach. Voltage is generally not required consistency. Since the LED is angled, so full-color LED display also has a directional point of view, that when viewed at different angles, its brightness is incremented or decremented. Thus, the red, green, and blue LED angle consistency will seriously affect the consistency of different angles, white balance, directly affecting the display of video color fidelity. To do the red, green and blue LED brightness variations at different angles to match the consistency, we need to package the lens design, raw material selection on strict scientific design, depending on package vendor technology. No matter how good the display method in the direction of balance, consistency is not good if the angle of LED, the entire screen white balance effect different angles will be bad. Consistency characteristic angle LED devices available LED Tester angle measured for the high-end display is particularly important. Full-color LED display dedicated LED Selection: full-color LED display dedicated most critical component is selected LED LED devices. There are three reasons: First, LED full-color machine is used in the largest number of key components, will use the thousands to tens of thousands per square meter LED; second, LED is to determine the performance of the entire body of the optical display screen, a direct impact on the audience Evaluation of the display; the third, LED display the largest proportion in the overall cost, from 30 [%] to 70 [%] range. LED is the key to full color LED display device, equivalent to the computer's CPU. LED selection has already decided the entire display 50 [%] or more of quality. If you fail to choose a good LED, other components of the display can not compensate for even the best display quality defects. Show full color LED display applications, ports, airports, railway stations, bus stations, major sports and exhibition venues, intelligent transport, highways, banks, advertising, electricity, commerce, telecommunications, hospitals, taxation, banking, market, public Square, almost all related systems and industry.
