The pixels include a plurality of first pixels and a plurality of second pixels adjacent to the first pixels. Each pixel includes a first display element, a second display element, a third display element. The Type-1 driving signals drive the first, second, and third display elements of the first pixels. The Type-2 driving signals drive the first, second, and third display elements of the second pixels. A first pulse of the Type-1 driving signals and a second pulse of the Type-2 driving signals are located at different time segments. By adopting the driver according to the present application, current concentration may be avoided and displaying quality may be improved. ## Claims ### Claim 1 A driver for a display panel, comprising: at least one driving circuit, generating a plurality of Type-1 driving signals and a plurality of Type-2 driving signals according to an input data, said Type-1 driving signals and said Type-2 driving signals driving a plurality of pixels of said display panel, said pixels including a plurality of first pixels and a plurality of second pixels adjacent to said first pixels, each said pixel including a first display element, a second display element, a third display element, said Type-1 driving signals driving said first, said second, and said third display elements of said first pixels, said Type-2 driving signals driving said first, said second, and said third display elements of said second pixels, said driving circuit determining a width of a first pulse of said Type-1 driving signals and a width of a second pulse of said Type-2 driving signals according to said input data, and said first pulse of said Type-1 driving signals and said second pulse of said Type-2 driving signals located at different time segments. ### Claim 2 (depends on 1) The driver of claim 1, wherein said Type-1 driving signals and said Type-2 driving signals have a signal period, a starting time located at said signal period of said first pulse of said Type-1 driving signals is different from a starting time located at said signal period of said second pulse of said Type-2 driving signals. ### Claim 3 (depends on 1) The driver of claim 1, wherein said Type-1 driving signals and said Type-2 driving signals have a signal period, said first pulse of said Type-1 driving signals and said second pulse of said Type-2 driving signals are located at different time segments of said signal period. ### Claim 4 (depends on 1) The driver of claim 1, wherein said Type-1 driving signals and said Type-2 driving signals have a signal period, said first pulse of said Type-1 driving signals is located at a fore end segment of said signal period and said second pulse of said Type-2 driving signals is located at a rear end segment of said signal period. ### Claim 5 (depends on 1) The driver of claim 1, wherein said Type-1 driving signals and said Type-2 driving signals have a signal period, said first pulse of said Type-1 driving signals is located at a fore end segment of said signal period;
