Patent ID: 8169240

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