Digitally driven gray scale operation of active matrix OLED displays

摘要: Disclosed is a pixel circuit consisting of MOS field-effect transistors (or thin-film transistors), capacitor, and an organic light-emitting diode that stores voltage signal used to control the amount light emitted from pixel. This in two-dimensional array form active-matrix OLED display. The at each during frame time controlled by dividing into many sub-frames changing stored beginning sub-frame such way integrated determines total emitted.
