Abstract:
1. A display apparatus, comprising: a light-emitting element for emitting light having a gradation level depending on supplied current; a pixel driving circuit for supplying the current to the light-emitting element depending on a voltage applied via a data line; a precharge voltage source for applying a predetermined precharge voltage to the pixel driving circuit via the data line; a voltage reader for reading the voltage of the data line a plurality of times with different timings in a predetermined transient response period after the application of the precharge voltage by the precharge voltage source; and a compensated gradation data signal generator for generating, based on a voltage difference among the voltages of the data line read at the different timings, a compensated gradation data signal having a voltage value corresponding to an element characteristic unique to the pixel driving circuit to apply the compensated gradation data signal to the pixel driving circuit.
