Abstract :
This paper presents a bidirectional OLED buck driver with the proposed variable-frequency control mechanism. The bulky parasitic capacitor of the OLED causes the significant delay on the dimming response of the OLED. Therefore, the bidirectional OLED buck driver with the variable-frequency control mechanism is proposed to increase the dimming response. Finally, the prototype circuit of a 6.4W bidirectional OLED buck driver with the variable-frequency control mechanism is built to verify the response performance.
