Display device, display device driving method, and electronic apparatus

摘要

A display device includes a pixel array portion and a driving portion for driving the pixel array portion. The pixel array portion includes row scanning lines, column signal lines, and pixels arranged in a matrix form at intersections of the scanning lines and the signal lines. The driving portion includes a write scanner for supplying a control signal to each of the scanning lines by sequentially scanning the scanning lines in each field and a signal selector for supplying a video signal to each of the signal lines in synchronization with the sequential scanning. The pixels each includes a storage capacitor, a light-emitting element, a sampling transistor for being turned on in response to the control signal, sampling the video signal, and storing the video signal in the storage capacitor, and a drive transistor for supplying a driving current to the light-emitting element in accordance with the stored video signal.

1. A display device comprising:
a pixel array portion; and a driving portion configured to drive the pixel array portion, the pixel array portion including row scanning lines, column signal lines, and pixels arranged in a matrix form, the driving portion including at least a write scanner configured to supply a control signal to each of the row scanning lines and a signal selector configured to supply a video signal and a predetermined potential to each of the column signal lines, each of the pixels comprising:
a storage capacitor;a light-emitting element;a first transistor configured to be turned on in response to the control signal and to supply the video signal from one of the column signal lines to the storage capacitor; anda second transistor configured to supply a driving current to the light-emitting element depending on the video signal stored in the storage capacitor, wherein the storage capacitor is connected to a control terminal of the second transistor, and wherein the first transistor is configured to obtain the predetermined potential from one of the column signal lines in response to the control signal supplied from the write scanner and to apply the predetermined potential to the control terminal of the second transistor to switch to a non-light-emission period from a light-emission period, and wherein the first transistor is configured to be turned on at a beginning of the non-light emission period, to be turned off before a threshold correction period, to be turned on again at a beginning of a signal writing period and to be turned off again at a beginning of the light-emission period.
