Abstract
An organic light emitting display and a method for making the same includes protection circuitry to avoid damage from static electricity. The display and method allow performing a lighting test during display manufacturing. The organic light emitting display includes a substrate, a display region on the transparent substrate with a matrix of pixels, and a signal transfer unit on the transparent substrate for transferring lighting test signals to the pixels. The signal transfer unit includes transistors for transferring the lighting test signals and a resistor coupled to drains and gates of the transistors for protecting the transistors against damage from static electricity.
