In recent years, LED screen rental market of unprecedented prosperity, leading the industry entered a rapid growth stage. In addition to the outdoor advertising screen is used, performing screen, traffic guidance screen, used in indoor LED display is also a huge potential market, including indoor monitoring large screen and indoor electronic curtain. According to the agency 's survey, in 2011 China LED display screen industry output value reached 21900000000 yuan, a year-on-year increase of 18%, according to the expected,2012-2015China LED display screen industry will maintain a growth rate of 15-20%.

But from a technical point of view,PAR 38 LED in fact, in the past 10 years or so, most manufacturers introduced LED display in the basic system architecture has not changed, only to certain technical index for the degree of improvement and correction. At the same time, in a high performance product popularization is also relatively lag, although some years before the market had with PWM ( pulse width modulation ) function display driver IC product launch, and market participants have agreed with PWM function with high refresh rate, constant current and other advantages, but because the element such as the price, so far this kind of high performance display driver IC market share is not high, the market application of larger or with basic majority (such as accumulation of5024/26), high-end products are mainly used in some of the more attention to the quality of LED screen rental market.

With PWM function of high-end drive IC products will become the main force to promote the development of the market,

And the LED screen color is more rich, more delicate, smooth image.

However, with the LED display screen market's rapid development, more and more users begin to display LED made from the visual effect, transmission, display mode,T8 LED Tubedab4d58ck to play mode and a series of complex requirements, this also makes LED display product faces a new technological innovation opportunity, but as a whole the display system" brain" -- LED drive IC will play a vital role.

Strengthen industry cooperation to break the technical bottleneck

LED display and data transmission between the general board is used in the serial data transmission mode ( SPI ), and then through the signal packet multiplexing technology synchronous transmission and display of data and control data, but in the refresh rate and resolution is enhanced in the case, very easy to cause the transmission of data of bottle neck, leading to system instability. In addition, in the LED display screen when the area is larger, the control lines are often very long, are susceptible to electromagnetic interference, affect the signal transmission quality. Although in recent years, some manufacturers have introduced a new transmission medium, but how can provide real and excellent performance, cost-effective products is a key problem to perplex industry. Therefore, some manufacturers put forward, LED display data transmission mode is in dire need of from the bottom of the technical aspects,reishi to find an innovative solution.

For example, some of the current driver IC attempts to use the standard CMOS technology equipped with high-speed LVDS circuit, so that the complex digital functions can be easily integrated into LVDS analog circuit, the serializer deserializer and integrated in the same chip. A 330mV LVDS transmission technology of low voltage differential signaling (250mVMINand450mVMAX ) and fast transition time, so that products can reach from 100Mbps to over 1Gbps high data rate; at the same time, the low voltage swing and differential circuit the output of the model is also effective to reduce the electromagnetic interference ( EMI ), to ensure the reliability of signal transmission.
