  • Patent number: 11963413
    Abstract: A liquid crystal display device includes: a substrate; a plurality of vertical organic light-emitting transistors; a data line that supplies a voltage to a gate electrode of the vertical organic light-emitting transistor; a thin-film transistor that is connected between the gate electrode of each of the vertical organic light-emitting transistors and the data line and controls supply of the voltage to the gate electrode of the vertical organic light-emitting transistor; a gate line that is connected to the gate electrode of the thin-film transistor and transmits a signal for switching the thin-film transistor; and a plurality of current supply lines that are wired in a first direction outside a formation region of the vertical organic light-emitting transistor, the current supply lines being in contact with a source electrode of the vertical organic light-emitting transistor to supply a current to the vertical organic light-emitting transistor.

  • Patent number: 11915644
    Abstract: Various examples are provided related to compensating brightness of a display using a vertical organic light emitting transistor that suppresses variations in brightness over a long period of time and a display. In one example, a method includes applying a voltage for brightness inspection to a gate electrode of the vertical organic light emitting transistor to be corrected, measuring a current flowing through a current supply line through which the current is supplied to a source electrode of the vertical organic light emitting transistor by the application of the voltage for brightness inspection to the gate electrode of the vertical organic light emitting transistor to be corrected, and determining a corrected value of the voltage to be applied to the gate electrode of the vertical organic light emitting transistor based on a value of the current and characteristic information of the vertical organic light emitting transistor stored in the memory.
