Patent ID: 8339427

Claim:
A drive method of a display apparatus for displaying image information in accordance with display data, wherein: the display apparatus includes a display panel in which a plurality of display pixels are arranged, each of the display pixels having a light-emitting element and a pixel drive circuit for controlling a light-emitting status of the light-emitting element, the pixel drive circuit includes at least: a first switching element which includes a control terminal and a current path, wherein a first end of the current path is applied with a power source voltage, a second end of the current path is connected to a connection contact point to a first end of the light-emitting element, and the connection contact point is applied with a data voltage based on the display data; a second switching element which includes a control terminal and a current path, wherein a first end of the current path is applied with the power source voltage and a second end of the current path is connected to the control terminal of the first switching element; and a voltage holding element connected between the control terminal of the first switching element and the connection contact point, and the drive method includes: a writing operation for electrically connecting the control terminal of the first switching element to the first end of the current path of the first switching element through the second switching element, applying the data voltage in accordance with the display data to the second end of the current path of the first switching element, and applying a first power source voltage as the power source voltage to the first end of the current path of the first switching element, wherein the first power source voltage has a potential higher than a potential of the data voltage corresponding to the display data and has a voltage value such that a potential difference between the first end of the current path of the first switching element and the second end of the light-emitting element is equal to or lower than a summed voltage as a sum of a voltage for starting light-emitting of the light-emitting element and a threshold voltage of the first switching element; and a light-emitting operation for electrically blocking the control terminal of the first switching element from the first end of the current path of the first switching element, and applying a second power source voltage as the power source voltage to the first end of the current path of the first switching element to flow a drive current based on a voltage component held by the voltage holding element in the light-emitting element, wherein the second power source voltage has a voltage value for causing the light-emitting element to be in a light-emitting status and is set to a potential different from the first power source voltage.
