Patent ID: 8169239

Claim:
A driver circuit, adapted to drive a display panel comprising N pixel cells on each of a plurality of scan lines, comprising: a plurality of source drivers, each source driver having M driving channels, wherein M≧N, and in accordance with a preset mode sequence, a first subset and a second subset of the driving channels of each source driver are respectively in a first mode and in a second mode, the source drivers at least comprising: a first source driver, the 1 st through N th driving channels of the first source driver are respectively used for driving the 1 st through N th pixel cells during a first scan period, wherein the used driving channels in the first subset of the driving channels of the first source driver sequentially activated by a first start pulse to receive a first pixel signal from a first data bus, and the used driving channels in the second subset of the driving channels of the first source driver sequentially activated by a second start pulse to receive the second pixel signal from the second data bus; and a second source driver, the M th through (M−N+1) th driving channels of the second source driver are respectively used for driving the 1 st through N th pixel cells during a second scan period; and a mode control unit, controlling the used driving channels in a third subset of the driving channels of the second source driver sequentially activated by the first start pulse to receive the first pixel signal from the first data bus, and the used driving channels in a fourth subset of the driving channels of the second source driver sequentially activated by the second start pulse to receive the second pixel signal from the second data bus, so as to make the driving channels of the first source driver and the second source driver at two ends of each of a plurality of data lines to receive the pixel signals from the same data bus.
