Title:
DISPLAY DEVICE AND METHOD FOR DRIVING SAME
Document Type and Number:
WIPO Patent Application WO/2021/079423
Kind Code:
A1
Abstract:
This display device is provided with: a plurality of scanning lines; a plurality of light-emitting control lines; a plurality of data lines; a plurality of pixel circuits; and a driving circuit that drives the scanning lines, the light-emitting control lines, and the data lines. Each of the pixel circuits includes a light-emitting element, and a driving transistor that controls the amount of current flowing through the light-emitting element. The driving circuit has a monitor mode, sets non-light-emitting periods of equal lengths and sequentially delayed for rows of the pixel circuits during a frame period of the monitor mode, selects a row to be measured as a monitor row from among the rows of the pixel circuits, sets a monitor period partially overlapping the non-light-emitting period of the monitor row, and measures characteristics of the driving transistor or the light-emitting element in the pixel circuit of the monitor row during the monitor period.
