Display driver circuitry supplies data and control signals to the pixels. Rows (RO, RM) in a first area (A) of the display are shorter than rows (RM+1) in a second area (B) of the dis- play. The display driver circuitry has gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive con- trol signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emit- ting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effect- ively applied to the drive transistor.
