12-2: Distinguished Paper: A 13-bit Universal Column Driver for Various Displays of OLED and LCD

A universal column driver is implemented in a 0.13‐µm highvoltage CMOS process for not only TFT‐LCD but also OLED applications. The proposed column driver employs 13‐bit linear DAC to cover all gamma curves of display applications and address‐based configuration for intra‐ panel interface protocol t...

Description
Summary:A universal column driver is implemented in a 0.13‐µm highvoltage CMOS process for not only TFT‐LCD but also OLED applications. The proposed column driver employs 13‐bit linear DAC to cover all gamma curves of display applications and address‐based configuration for intra‐ panel interface protocol to support both TV and IT applications. Measured results demonstrate the average voltage of output channels (AVO) is under 1mv, which satisfies 1‐LSB resolution at 18.5V of AVDD.
