Patent abstract
A display panel driver including a binary-weighted current-type D/A converter and a source follower with current mirror is provided. The binary-weighted current-type D/A converter receives n input signals and sends a D/A output voltage signal based on 2n−1 times a reference current. The source follower with current mirror receives the D/A output voltage signal and sends 2n−1 times the reference current to the output of the source follower with current mirror, so as to output a output voltage and drive the display panel.
