LED driver application and driving method

Posted by: admin  • Information section:LED

At present, LED is developing rapidly, technology is becoming more and more mature, and LED technology is gradually becoming popular in various aspects. Many LED products have attracted the attention of the public with high-quality pictures and energy-saving energy consumption. But the related operation of led is not a seemingly simple thing, you need to require the device to drive the program with strict and fine requirements. The following is a related explanation of the LED core driver application and driving method of the LED.

Talking about the application and driving method of LED driver
 



LED driver application

Since LED applications are used in almost every field of electronics applications, changes in luminous intensity, light color, and on-off control are almost unpredictable, so LED drivers become almost one-to-one servo devices, making this device Family members have become diverse. The simplest LED driver (if it can be called this way) may be one or several series-parallel RC components that split the voltage divider in the loop, which is not a separate product at all. For more general commercial applications that require a stable constant current and constant voltage output, a series of system solutions with precise power supply adjustment capabilities are formed. Implementing these solutions often requires a more complex circuit design, the core of which is the integrated application of LED driver ICs. By setting up different support circuits on the periphery of the LED driver IC, we can build solutions for different LED applications, from mobile phone display backlights and button light drivers, to high-power LED street lights and large outdoor LED displays.

More general-purpose high-power LED driver design and supply, generally by professional companies. These companies supply them to the LED terminal application product manufacturers after they are packaged into modules. Driver designs for less common LED terminal applications may require hands-on design. It has become an important part of the unique technical content of this LED terminal application. Because the LED as the packaged product is upstream, its technical performance has been solidified in the LED product, and the unique terminal LED application product is created. In addition to the LED driving function, the light source can be used in other places. It is not much.

Due to the unique importance of LED drivers in LED applications and a wide range of user requirements, LED driver ICs, which are the heart components of LED drivers, have become a key element in the entire technology chain. It has prompted many manufacturers, including listed companies, to use LED driver as their main product, and supply LED driver ICs to downstream industries, such as Hangzhou Silan Micro, Shenzhen Quanxin Electronics, Shenzhen Guanghuayuan Technology, Shenzhen Guowei Electronics, China Resources. Converse Technology, Taiwan's dot crystal technology, accumulation technology, Guangpeng technology, Taiwan crystal technology, Feihong, Maoda, Yuanchuang and so on. There are also many American manufacturers with industry leaders in this field, such as National Semiconductor, Maxim, Texas Instruments, ON Semiconductor, Linear Technology, Fairchild Semiconductor, etc.

In the full-color LED video display, it is a display that can display images and animations in millions of colors. LED display applications include stadiums, building exteriors, shopping centers, and television studios. Large LED displays are used to play advertisements and information, replay sports events or concerts. The working principle of the LED driver: the video input signal provided by different types of video sources is processed and sent to the LED display. The entire display usually consists of a number of square or rectangular lattices, each consisting of several pixels. Each pixel consists of RGB (red, green, blue) LED tubes that, by mixing the light colors of these LEDs, produce the desired pixel information. The LED driver is equivalent to the interface between the processed video data and the colored lights emitted by the RGB LEDs (the image is composed of these colored lights). The signal quality of the original image and the data processing capability are prerequisites for achieving good image quality. The size of the display, the resolution, pixel pitch and LED selection are key parameters that determine the quality of the human eye. You need to choose a suitable LED driver that converts the processed image data into the desired color and animation effects. In terms of color and animation, in order to achieve excellent image quality, it is necessary to integrate a variety of different functions: high frame rate, high refresh rate, color reproduction accuracy, and the like. However, the quality of the display refers not only to the image itself, but also to the overall quality of the solution, such as immunity to interference and reliability. Therefore, all color LED displays require the selection of sophisticated LED drivers.
