Patent ID: 8587566

Claim:
A driver for driving a plurality of pixel circuits each including a light emitting element, the driver comprising: a plurality of input pads arranged along a first line; and a plurality of pad sets corresponding respectively to the pixel circuits, each pad set including a plurality of control pads and at least one power source pad having a larger area than the control pad, an order of arrangement of the control pads and the power source pad being the same in each pad set, the control pads being connected to a corresponding pixel circuit to supply control signals for controlling a corresponding light emitting element to the corresponding pixel circuit, the power source pad being connected to a corresponding pixel circuit for supplying power to the corresponding pixel circuit to drive a corresponding light emitting element, the pad sets being arranged so that the respective control pads and the respective power source pads are symmetrically arranged along a second line adjacent to and parallel to the first line.
