Abstract:
1. A display apparatus which displays image information in accordance with display data, the display apparatus comprising: a display panel comprising a plurality of display pixels respectively arranged in vicinities of intersection points of a plurality of selection lines arranged in a row direction and data lines arranged in a column direction, each of the display pixels including a light-emitting element and a drive element for supplying current in a current path to the light-emitting element; a selection driving section which sequentially sets, via each of the selection lines, the display pixels in the corresponding rows to a selected status; a data driving section which generates gradation signals in accordance with the display data, wherein the data driving section comprises a gradation voltage compensation circuit which generates compensated gradation voltages and supplies, via the respective data lines, the generated compensated gradation voltages as the gradation signals to the respective display pixels in the row set to the selected status; a memory circuit where a specific value corresponding to an element characteristic of the drive element in each of the display pixels is stored; and a power source driving section which supplies a power source voltage; wherein the gradation voltage compensation circuit generates the compensated gradation voltage corresponding to one of the display pixels by adding a gradation voltage corresponding to the display pixel to a compensation voltage corresponding to the display pixel, the gradation voltage having a voltage value for causing the light-emitting element to emit light with a brightness corresponding to a luminance gradation indicated by the display data, and the compensation voltage being based on the specific value corresponding to the display pixel obtained from the memory circuit, and wherein the power source driving section generates, as the power source voltage, a first voltage for setting the light-emitting element to a no-light-emitting status and a second voltage for setting the light-emitting element to a light-emitting status; supplies the first voltage to the respective display pixels to be supplied with the gradation signals for a period which includes and is longer than a selected period to set the light-emitting elements of the respective display pixels to the no-light-emitting status for a period longer than the selected period; and supplies the second voltage to the respective display pixels to set the light-emitting elements of the respective display pixels to the light-emitting status.
