Measurement circuit for leakage current of capacitor
A measurement circuit includes an instruction input unit, a charging circuit to charge a capacitor, a charging and discharging circuit to control the capacitor to leakage discharge, a control circuit, a first amplifying circuit, and a display unit. The control circuit receives a measurement instruction through the instruction input unit to control the charging circuit to charge the capacitor, and receives a stop charging signal from the charging circuit when a voltage of the capacitor reaches a saturation voltage for controlling the charging circuit to stop charging the capacitor.

Pixel and organic light emitting display device having the same
A pixel of an organic light emitting display device includes a transistor configured to output a first source voltage, an organic light emitting diode coupled to the transistor, and a wiring configured to be applied with a reference voltage to ground a leakage current of the transistor. The organic light emitting diode includes a first electrode configured to receive the first source voltage, a first common layer on the first electrode, an organic light emitting layer on the first common layer, and a second electrode on the organic light emitting layer and configured to be applied with a second source voltage different from the first source voltage.

Array operation using a schottky diode as a non-ohmic selection device
A two-terminal memory cell including a schottky metal-semiconductor contact as a selection device (sd) allows selection of two-terminal cross-point memory array operating voltages that eliminate “half-select leakage current” problems present when other types of non-ohmic devices are used. The sd structure can comprise a “metal/oxide semiconductor/metal” or a “metal/lightly-doped single layer polycrystalline silicon.” the memory cell can include a two-terminal memory element including at least one conductive oxide layer (e.g., a conductive metal oxide—cmo, such as a perovskite or a conductive binary oxide) and an electronically insulating layer (e.g., yttria-stabilized zirconia—ysz) in contact with the cmo.
