  • Patent number: 11158256
    Abstract: A display may include an array of organic light-emitting diode display pixels having transistors characterized by threshold voltages subject to transistor variations. Compensation circuitry may be used to sense a current from selected display pixels. A display pixel may include a drive transistor, a gate setting transistor for driving a reference voltage onto the gate terminal of the drive transistor, a data loading and current sensing transistor for connecting the drive transistor to a data/current-sensing line, a light-emitting diode, an emission control transistor coupled between the drive transistor and the diode, and an anode resetting transistor for selectively resetting the anode terminal of the diode. During in-frame current sensing operations, the emission control transistor may be turned off to decouple the drive transistor from the diode, thereby blocking off any residue current and lateral leakage current that may be present at the diode.

    Abstract: Various embodiments of the present disclosure provide a via-first process for connecting a contact to a gate electrode. In some embodiments, the contact is formed extending through a first interlayer dielectric (ILD) layer to a source/drain region bordering the gate electrode. An etch stop layer (ESL) is deposited covering the first ILD layer and the contact, and a second ILD layer is deposited covering the ESL. A first etch is performed into the first and second ILD layers and the etch stop layer to form a first opening exposing the gate electrode. A series of etches is performed into the second ILD layer and the etch stop layer to form a second opening overlying the contact and overlapping the first opening, such that a bottom of the second opening slants downward from the contact to the first opening. A gate-to-contact (GC) structure is formed filling the first and second openings.
