Pixel circuit driving method, pixel circuit, electro-optical device, and electronic apparatus

摘要

To effectively reduce or prevent the deterioration of display quality caused by the errors included in the current supplied to an electro-optical element a pixel circuit includes a capacitor C 1 , transistors T 1 and T 2 that constitute a current mirror, and an organic EL element OLED. When a first driving mode is set, the transistor T 1 functions as a programming element that writes data in the capacitor C 1 in accordance with data current Idata and the second transistor T 2 functions as a driving element that generates driving current Ioled in accordance with data stored in the capacitor C 1 . When the second driving mode that is alternately switched to the first driving mode in a predetermined period is set, the transistor T 2 functions as the programming element and the transistor T 1 functions as the driving element.
