LED display prices _LED electronic display _ _ Shenzhen LED display manufacturer in Shaanxi Hi-Tech Optoelectronic led electronic display is a set of microelectronics, photonics technology, computer technology, information processing technology in one large display systems. With its colorful, wide dynamic range, high brightness, long life, stable performance and becoming the leader in display media are widely used in advertising, securities, information dissemination, press releases, etc., is highly advanced international The display media. led electronic display (led panel) is controlled by a certain way, led screen for displaying an array of devices, text, graphics, images, animations, quotes, video, video signals and other information display composed. Historical Evolution of the traditional white light volume display method, although unable to overcome the colors brighter, but the change monotone its power consumption, short life of the defects, neon signs, advertising light boxes, advertising signs and other plane, but can not play video ads; magnetic pirated although can computer assembled by simple design, but do not have their own light source, for use at night is poor. In recent years, with the rapid development of microelectronics technology, automation technology, computer technology, updating and application of new materials, production processes, so that the luminance LED chips, life has been rapid development, making it an increasingly wide range of applications, LED display market has been considerable development. 93 years later, ultra-bright blue, red, a green light-emitting tube, so as to achieve true color display become a reality, to get people's favorite outdoor display, particularly used in sports venues, advertising, news and other areas increasingly widespread. From the future development trend, several kinds of media with video effects, its performance advantage is different, cathode tube (crt) or quartz tube (dv) Large TV: the cost is very expensive and usually only do 37 inches, the volume is bigger on To be limited, no longer need a large screen and, when used indoors, the results are satisfactory. Color liquid crystal display (led): the same expensive, circuit complexity, the area is not too large, but also affected by the viewing angle is very large, the viewing angle is very small, but the picture is fine, good visual sense. Image projection apparatus (projector): brightness small, poor resolution (screen by light uneven), the advantage of easy installation and simple maintenance. TV wall (tv-wall): the surface of the dividing line, a foreign body sensation Visually, when poor brightness outdoor applications, suitable for representing text, but the TV screen when the indoor performance to good effect. led a smaller space constraints, and users can request the size of the screen design, with full-color effect, viewing angle characteristics, may represent text, graphics, images (including animation and video). The rapid development of China's economy, on the dissemination of information have higher requirements. It is believed, led electronic display with its bright colors, display information capacity, long life, power consumption is small, light weight, small space size, high stability, easy to operate, easy installation and maintenance features will be developed in the socio-economic play an increasingly important role. Somehow it seems, led display in today's media, the highest price, is your best choice. LED display applications: Rousseff lossew.ow in 1923 discovered the light-emitting semiconductor sic pn junction formed by accident, but the use of a semiconductor pn junction electroluminescence principle of light-emitting diodes made only to the late 1960s before to develop rapidly. In recent years, due to the production and processing of semiconductor gradually mature and perfect, light emitting diode (led: light emitting diode) displays have become increasingly dominant in the solid position. led reason why widespread attention and rapid development, is that it itself has the advantage inseparable. They sum up these advantages are: high brightness, low voltage, low power consumption, miniaturization is easy to match with the integrated circuit, driving a simple, long life, impact resistance and stable performance. led the broad prospects for development, the current is moving higher brightness, higher weather resistance, higher luminous uniformity, reliability, full color direction. Because of different semiconductor materials can be led emit different colors of light-emitting chips. Traditional methods and large scale video display system programmable integrated chip video shows discrete small-scale integrated circuit technology. When the system to improve the performance of large-scale (such as 16 gray increased to 256 gray levels), this technology will seriously affect system reliability and maintainability. After the gray level increased with increasing amount of data operation, we had to take a more complex, more numerous small-scale discrete components, which will enable the reliability and maintainability of the system is difficult to ensure. In addition, the instrument visually distinguish the difference between the brightness level of feeling different, visually sensitive to low brightness differential, high brightness ratio can not be clearly distinguished. This requires led emitting device nonlinear visual correction, compression low brightness differential, differential expansion of high brightness, the ash level in line with the degree of difference between the actual display macroscopic physical senses. This method will increase the difficulty and computational operations, more complex circuit design. In order to solve these two problems, improve the display effect, reducing design complexity, to ensure system reliability and maintainability, gold Canal Company from 1998 began VLSI chip design. Chip integration density of 80,000 circuits using hardware description language design, abandoned the use of small-scale integration devices, adding a large number of complex logical operations. This achievement paved the above two technical obstacles, which greatly improves the performance of the system. 256 gray super integrated video display control system centralized control of design ideas, using a unique "8421 encoded data control flow" control scheme design is complete, greatly improved the led display control section of accuracy, stability, reliability sex, after a lot of complex visual correction operation, improve the color gray levels visible. So 256 grayscale display has led significant improvements in brightness, color excessive smoothness, contrast, etc., while increasing the mosaic can be arbitrary, can not plug or unplug, anti-static, and other functionality. Which greatly limits to meet the led display is a semi-permanent electronic products this requirement. Thus, production, installation, maintenance, upgrades have become convenient and easy. 90% of the control process focused on the host system, and the body is just a basic display driver circuit, and no complicated control circuit, thereby increasing the reliability and maintainability of the system, and greatly reduces the control circuit costs, reduced hardware costs led screen.
