LED oled module technology 50 years Secret History Review

The first LED lights red. This is not for aesthetic reasons. The LED is formed by a multilayered semiconductor wafer on the wafer. As more and more semiconductor wafer layer is added up, people began to use a variety of additives to determine the color of the LED light. Small silicon immersed in the molten liquid, then add the metal contacts and leads. The first LED light LED light the GaAsP solution will produce a natural red. Therefore, the default color is used as the indicator LED lights red.128x64 lcd display
Made use of new technology LED lights can also send other colors of light, which greatly expanded the range of applications of LED lights. But in the first 10 years after the advent of the LED lights, the light emitted by this light is red.
Relatively inexpensive, low-power LED lights began to replace incandescent bulbs in a variety of electronic products, electronic products prices subsequently fell, down to an easier level accepted by consumers.
In 1972, there has been a century-long watch technology have begun to accept the LED lights. Unfortunately, the high power consumption of this new technology, so wear this watch need to press a button to see the time.
From the light to the lighting
In 1993, the capsule accidentally found a method which enables the LED lamp emits blue light. This further expands the range of applications for LED lights, the LED light from the indicator to the lights.
With the the light emitted LED lights become more and more strong, the flashlight industry began to replace incandescent lamps with LED lights. The flashlight use energy is relatively small, the bulb basically do not have to be replaced. Is now difficult to find do not use the LED flashlight.
Optical Mouse with LED lights connected together with a group of image sensors that can track the trajectory of the mouse on any flat surface. The advent of optical mouse at the same time, also declared the end of the product life mouse pad.
Over the past 15 years, the HDTV industry has maintained a rapid development. CRT has quit the stage of history, HDTV unified market. Promote an important component of this trend is an LED. LED backlight technology instead of CCFL backlight technology, LED backlight technology provides higher contrast and a wider color gamut. Furthermore, LED backlight TV technology also help reduce energy consumption.
However, LED technology for high-definition TV penetration did not stop in backlight technology.16x2 oled
Organic carbon components used in the OLED light when an electric current passes through, so that you do not have to also configure the backlight assembly. Therefore, the thickness of the OLED TV is only 4 mm, and weighs only 16 pounds. Compared to LCD TV, OLED TV use less energy, support viewing angle wider generate the color more rich and colorful, with higher contrast.
