LED Display Development Process

Led Curtain Display was born in 1923, Lossen. O. W found in the study of semiconductor pn junction sic adulterated, the power light will be emitted, which developed a light-emitting diode (led: light emitting diode), but after the application of LED has been taken seriously. With the rapid development of the electronics industry in the 1960s, showing the rapid development of technology, people come up with pdp laser display, plasma display panels, LED liquid crystal displays, light emitting diodes led, other display technologies. Due to the production and processing of semiconductor gradually mature and perfect, light-emitting diodes have become increasingly dominant in the solid display. The reason why LED widespread attention and rapid development, because it itself has a lot of advantages. For example: high brightness, low voltage, low power consumption, ease of integration, driving a simple, long life, impact resistance and stable performance, and its extremely broad development prospects. Current is moving higher brightness, higher weather resistance and luminous density, light uniformity, full color development. With the development, people need - kind of large-screen display devices, so with a projector, but its brightness can not be used in natural light, so there is a LED display (screen), it has a large viewing angle, high brightness, colorful features . Development of LED large screen showed the following several stages of development:

1, the first generation: monochrome LED display

Single red for the color, display text and simple design, mainly used for notifications, circulars and traffic guidance systems.

2, the second generation: two-color multi-grayscale display

Red and yellow-green color, because there is no blue, only referred to as pseudo-color, grayscale images and can display multiple video, currently in the country are widely used in telecommunications, banking, taxation, hospitals, government agencies and other occasions, mainly display posters, public service advertising and image advertising information.

3, the third generation: Full color (full color) grayscale display more

Red, blue and yellow-green color, you can display a more realistic image, the current is gradually replace the previous generation products.

4. Fourth generation: True color (true color) grayscale display more

Red, blue and pure green color, can be a true representation of all the colors of nature (in the color coordinate even more than the natural color range). You can display a variety of video and color advertising, its bright colors, bright, high-brightness, contrast and delicate, in the field of advertising applications with excellent visual shocking. True color 5mm within households belong to the big screen in the fourth generation. It has a high brightness, brightness without environmental impact, thin, small space occupied, rich color, wide viewing angle, in the spacious hall environments, there is no loss of image stitching. LED was born in 1923, Rousseff (lossen.o.w) found adulterated sic semiconductor pn junction in the study, the light will be emitted after power, which developed a light-emitting diode (led: light emitting diode ), but after the application of LED has been taken seriously. With the rapid development of the electronics industry in the 1960s, showing the rapid development of technology, people come up with pdp laser display, plasma display panels, LED liquid crystal displays, light emitting diodes led, other display technologies.
