Display driving method with multi-type common voltages and display driving circuit using the same

摘要

A display driving method including the following steps is provided. A common voltage is provided to define a reference voltage of a display. The reference voltage is sequentially switched between a plurality of AC voltage swings, between a plurality of DC voltage levels, or between one or more AC voltage swings and one or more DC voltage levels. Each of the plurality of AC voltage swings is provided for a time length of one or more frames. The step of providing the common voltage is repeated one or more times. A display driving circuit using the same is also provided.

1. A display driving method comprising:
providing a common voltage to define a reference voltage of a display, wherein the reference voltage is sequentially switched between one or more alternating current (AC) voltage swings and more than one direct current (DC) voltage levels, and each of the one or more AC voltage swings and the more than one DC voltage levels is provided for a time length of one or more frames; and repeating the step of providing the common voltage one or more times such that the sequence of the one or more AC voltage swings and the more than one DC voltage levels is repeated in each of the one or more times, and the respective time length of each of the one or more AC voltage swings and the more than one DC voltage levels is repeated in each of the one or more times.
