Patent ID: 7570257

Claim:
A display device having a plurality of pixels arranged in a matrix and a vertical driver which sequentially drives the plurality of pixels, wherein each of the plurality of pixel comprises: an element to be driven; a selection transistor which reads a data signal from a data line extending along a vertical scan direction according to a selection signal output on a selection line extending along a horizontal scan direction; a storage capacitor having a first electrode and a second electrode and which stores, as a voltage with respect to a voltage supplied from a capacitor line to the second electrode, a data signal from the selection transistor supplied to the first electrode; and an element driving transistor having a gate connected to the first electrode of the storage capacitor and which supplies power corresponding to a data voltage stored in the storage capacitor from a power supply to the element to be driven, a plurality of the selection lines are provided, each of which extends along the horizontal scan direction, the vertical driver comprises a vertical transfer register having a plurality of stages of registers which sequentially read and transfer a vertical start signal indicating a start timing of one vertical scan period, a selection signal generator which generates the selection signal to be supplied to the selection line, and a capacitor control signal generator which generates a capacitor control signal to be supplied to the capacitor line, the selection signal generator generates, based on the vertical start signal, the selection signals at timings which differ from each other by one horizontal scan period to be sequentially supplied to the selection lines, the capacitor control signal generator generates the capacitor control signal based on an output, corresponding to the vertical start signal, from the register of each stage of the vertical transfer register, and the capacitor control signal has a first voltage level state which causes the storage capacitor to store the voltage corresponding to the data signal via the capacitor line and causes the element driving transistor to operate according to the stored voltage and a second voltage level state which causes a corresponding element driving transistor to be controlled to be switched off.
