| Abstract: | White LED is used in more and more areas. The two main areas are illumination and backlight for LCD. The efficiency of the DC-DC converter is regarded as the important part in battery-powered handled devices. In the backlight for full-color LCD treated with many LED, brightness matching is the determinant factor in quality of backlight. Based on the above two sides, this article will synthesize, analyze and contrast the white LED drivers in handled devices about sorts, characters and applicable areas. |
