Abstract
In order to improve the quality of image of LED display,a high refresh rate and high stability LED con-stant current drive circuit was designed. A complete PWM is divided into 32 sections. A novel counter is designed by modified the M-serial to produce irregular PWM,improves visual refresh rate. At the same time,improve the band gap reference source and using high output impedance current mirror to improve the stability of current.关键词
