Abstract: As a result of miniaturization of a pixel region associated with an improvement in definition and an increase in a substrate size associated with an increase in area, defects due to precision, bending, and the like of a mask used at the time of evaporation have become issues. A partition including portions with different thicknesses over a pixel electrode (also referred to as a first electrode) in a display region and in the vicinity of a pixel electrode layer is formed, without increasing the number of steps, by using a photomask or a reticle provided with an auxiliary pattern having a light intensity reduction function made of a diffraction grating pattern or a semi-transmissive film.

Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. 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 control 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-emitting 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 effectively applied to the drive transistor. The display driver circuitry may have 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.
