Abstract
A control element of an organic electro-luminescent display includes a first transistor, a second transistor and a capacitor. The first gate electrode of the first transistor is electrically connected to a scan line, and the first source/drain electrode of the first transistor is electrically connected to a data line. The second gate electrode of the second transistor is electrically connected to the second source/drain electrode of the first transistor. The third source/drain electrode of the second transistor is electrically connected to a working voltage, and the fourth source/drain electrode of the second transistor is electrically connected to a light emitting diode. One end of the capacitor is electrically connected to the second gate electrode. The material of the dielectric layer of the capacitor is different from the material of the gate dielectric of one of the first transistor and the second transistor.
