Abstract:
A display panel comprising:a pixel array comprising: a plurality of pixel elements arranged in a matrix along a row direction and a column direction, each said pixel element comprising: a light emitting device; a memory cell which is associated with said light emitting device and physically disposed within said pixel element; and a metal oxide semiconductor (MOS) transistor having a gate which receives data from said memory cell and activates and deactivates said light emitting device based on said data; a plurality of word lines each disposed for a corresponding row of said pixel elements; and a plurality of bit lines each disposed for a corresponding column of said pixel elements; an address port for receiving an address signal including a row address and a column address; a row address decoder for receiving said row address from said address port of specify one of said word lines; a column address decoder for receiving said column address from said address port to specify one of said bit lines; and an input/output buffer having a write mode for writing data through said specified bit line to one of said memory cells corresponding to said specified word line, and a read mode for reading data from said memory cell controlling an associated one of said light emitting devices, said buffer transmitting display data from said pixel array to a processor during said read mode.
