Abstract :
An overview of the electronics used to drive the light emitting diodes (LEDs) displays is presented. The common problems and the solutions are given. The driver technologies overview indicates the remaining challenges: the high current distribution and the LED dimming range. New driver topology suggested could solve the mentioned shortcomings.
