Abstract: A display device includes pixel units, a source driver and a control unit. The source driver applies voltage corresponding to gray level values to data signal lines. Each of the pixel units includes a light-emitting element, a capacitance element and a driving transistor. The light-emitting element emits light according to a driving current. The capacitance element accumulates charge corresponding to a voltage at a connected data signal line. The driving transistor supplies the driving current corresponding to the accumulated charge to the light-emitting element. The control unit decreases voltage(s) to be outputted from the source driver, when an appearance frequency of display pixels having a low gray-level value is lower than a first reference frequency, or when an appearance frequency of display pixels having a high gray-level value is lower than a second reference frequency.

Abstract: A vapor deposition method for depositing different vapor deposition materials onto a vapor deposition target provided in a chamber is disclosed. A first vapor deposition material is heated, via a first heater, for a predetermined period for increasing a temperature of the first vapor deposition material. Based on the increased heat, vapor of the first vapor deposition material is ejected from a first vapor deposition source towards the vapor deposition target. After the predetermined period has elapsed and via a second heater, the second vapor deposition material is heated for increasing a temperature of a second vapor deposition material. Based on the increased heat, vapor of the second vapor deposition material is ejected from a second vapor deposition source towards the vapor deposition target. The first vapor deposition material contains an organic functional material, and the second vapor deposition material contains a metal material.
