Generally, a sub-pixel 72 is operated to emit light through receiving one or more control signals, such as, from the column driver 62 and/or the row driver 60. The row driver 60 and the column driver 62 may control operation of the sub-pixel 72 by using control signals to control components of the sub-pixel 72, such as a current drive of the sub-pixel 72. As described above, the column driver 62 may be responsible at least for the transmission of image data to the sub-pixel 72 while the row driver 60 may be responsible for one or more control signals to control emission that transmit to the sub-pixel 72. The sub-pixel 72 may include any suitable controllable element responsive to these control signals and image data, such as a transistor, one example of which is a metal-oxide-semiconductor field-effect transistor (MOSFET). However, any other suitable type of controllable elements, including thin film transistors (TFTs), p-type and/or n-type MOSFETs, and other transistor types, may also be used.
