Abstract

An Organic light emitting diode (OLED)/polymer OLED (PLED) displays and their operation with a precharge latency. Particularly, precharging operation of such a display device with a precharge switch latency. According to the operation, a capacitive aspect of a display element is precharged, i.e. the parasitic capacitance, and the display element is activated so as to conduct a current therethrough. The precharging is terminated after the activation of the display element. Then a current is supplied and conducted through the display element for exposure of the display element. In this operation, a precharge and exposure can be avoided or minimized by maintaining the connection of the voltage source to the column lines during an overlap period after the row line is grounded.
