Abstract

In this paper, a 10-bit area-efficient source driver circuit is proposed for printed OLED panel. Fast discharge structure is proposed in the interpolation circuit which decreases the static current and reduces the number of transistors. By rearranging the input signals of the voltage selector, the number of switches decreases to 270, which is 53% of the traditional tree structure. Gamma correction circuit is integrated in the chip, which corrects the output voltage of red, green and blue, respectively. The area of the single channel is only 1182μ m ×28 μm using 0.18μm BCD high-voltage process. The maximum output voltage ranges from 2 V to 13.5V for the source driver. The static current of the single channel is 6.5μ A with 6.5k ω resistance and 100pF capacitance load.
