Abstract: A method of generating column signals for use by a pixel array includes connecting two or more controllable bus buffers in series. The output of each of the two or more controllable bus buffers drives an associated node. The method further includes providing a column data signal to an input of the series-connected string of two or more controllable bus buffers. The method also includes sequentially enabling each controllable bus buffer in the series-connected string of two or more controllable bus buffers, such that each node is sequentially driven. Each node is electrically coupled to an input of an associated controllable local output buffer. The method further includes sequentially enabling each of the controllable local output buffers in an order associated with the sequentially enabling of the controllable bus buffers.

Abstract: A unit pixel driver circuit includes a capacitor configured to store a voltage corresponding to a desired pixel brightness and a control block. The control block may include a first, second third and fourth transistors, all of which are connected together, both in parallel and in series. The control block controls, based on the voltage stored in the capacitor, the amount of current flowing through a pixel LED. The first transistor, second transistor, third transistor and fourth transistor all share a common gate geometry size.

Abstract: A method of driving a pixel array includes providing a ramp signal to one or more columns of the pixel array. For each cycle of the ramp signal, the method further includes providing a first row driving signal to at least a first row of the pixel array and a second row driving signal to a second row of the pixel array.
