In recent years, the LED electronic screen market has been very popular, driving the entire LED electronic screen industry into a stage of rapid growth. In addition to advertising screens, performing arts screens, traffic guidance screens, etc., which are widely used outdoors, the application of indoor LED electronic screens is also a market with huge potential, including indoor monitoring large screens and indoor LED electronic screens. But from a technical point of view, in fact, in the past 10 years or so, the LED electronic screens introduced by most manufacturers have not changed much in the basic system architecture, but have made certain technical indicators to a certain extent. Improvements and corrections.

  At the same time, the popularization and promotion of high-performance products is relatively lagging, although as early as a few years ago, there were already display driver IC products with PWM (Pulse Width Modulation) function on the market, and market participants have also agreed with the PWM function. It has the advantages of high refresh rate and constant current. However, due to price and other factors, the market share of such high-performance display driver ICs is still not high. The basic models are mostly used in the market (such as Macroblock 5024/ 26 etc.), high-end products are mainly used in some LED electronic screen rental markets that pay more attention to quality.

  However, with the rapid development of the Shenzhen LED electronic screen market, more and more users have begun to put forward a series of complex requirements for LED electronic screens from visual effects, transmission methods, display methods, and playback methods. This also makes LED screen products are facing a new opportunity for technological innovation, and as the "brain" of the overall display system-LED driver IC will play a crucial role.

  The data transmission between the LED electronic screen and the motherboard generally adopts the serial data transmission method (SPI), and then transmits the display data and control data synchronously through the signal packet multiplexing technology, but when the refresh rate and resolution are improved Down, it is easy to cause a bottleneck in data transmission, leading to system instability. In addition, when the LED electronic screen area is large, the control line is often very long, which is susceptible to electromagnetic interference, which affects the quality of the transmission signal.

  Although some manufacturers have introduced new transmission media in recent years, how to provide users with truly excellent performance and cost-effective product solutions is a key issue that plagues the industry. For this reason, some manufacturers have proposed that the data transmission method of LED electronic screens urgently needs to start from the lowest technical level and find an innovative solution.

  It is worth noting that the technological innovation of LED electronic screens has involved all aspects of the industrial chain, including the improvement of driver IC production process, the hardware of control system, the intelligent development of control software, etc. These technological innovations require IC design manufacturers, Control system developers, panel manufacturers, and even end users are more closely integrated to break the "deadlock" of industry applications. Especially in the development of control systems, how to better cooperate with IC design companies to improve the system performance of LED electronic screens and the intelligent level of control software is a top priority.
