Patent ID: 8144083

Claim:
A light-emitting device, comprising: a plurality of scanning lines; a plurality of data lines that intersect the plurality of scanning lines; a plurality of pixel circuits arranged corresponding to the intersections of the scanning lines and the data lines, each pixel circuit including: a light-emitting element; a driving transistor that controls an amount of a driving current flowing to the light-emitting element in a light-emitting period of a frame in which the driving current is supplied to the light-emitting element after a writing period is terminated in the frame; and a write transistor being a single transistor controlled by a first scanning line of the plurality of scanning lines, wherein a plurality of sequential horizontal scanning periods precede the light-emitting period of the lighting emitting element in the frame, and each horizontal scanning period has a first period half and a second period half immediately following the first period half, wherein the plurality of sequential horizontal scanning periods correspond with the writing period and at least two correction periods preceding the writing period, and wherein the writing period corresponds with one horizontal scanning period in which the write transistor is maintained in an on state for the first period half and the second period half followed by one horizontal scanning period in which the write transistor is maintained in an off state for the first period half and the second period half, a first half of the first period half of the first of the plurality of sequential horizontal scanning periods is an initialization period and in the initialization period, an EL transistor is turned on and a gate potential of the driving transistor is set to an initialization potential, in the at least two correction periods corresponding with horizontal scanning periods preceding the writing period the first scanning line of the plurality of scanning lines and a first set line are selected in the first period half of the corresponding horizontal scanning periods, and a data line of the plurality of data lines supplies a reference voltage to a pixel circuit connected to the first scanning line such that a voltage is generated in the pixel circuit for compensating a threshold voltage of the driving transistor, in the writing period after the correction periods, the first scanning line of the plurality of scanning lines is selected, and the data line supplies to the pixel circuit a data signal corresponding to a brightness to be emitted by the light-emitting element of the pixel circuit, the data line supplies the reference voltage and the data signal to the pixel circuit via the write transistor, and the initialization potential is a substantially ground potential raised by a threshold voltage of the light-emitting element.
