Patent ID: 8350797

Claim:
A display driver comprising: a first buffer amplifier including: a first input stage having high and low power voltages applied thereon; and a first output stage having the high power voltage applied thereon, and having a first reference power voltage that is higher than the low power voltage applied thereon; and a second buffer amplifier including: a second input stage having the high and low power voltages applied thereon; and a second output stage having the low power voltage applied thereon, and having a second reference power voltage that is lower than the high power voltage applied thereon; wherein the first reference power voltage is applied instead of the low power voltage on the first output stage, and wherein the second reference power voltage is applied instead of the high power voltage on the second output stage, and wherein the first reference power voltage is lower than a common voltage of a display panel, and wherein the second reference power voltage is higher than the common voltage, and wherein the first buffer amplifier and the second buffer amplifier are coupled in parallel.
