Title: Display device
Inventor: MIYAKE HIROYUKI
IPC: H05B44/00
Filed: 2020-03-25
Abstract: To provide a display device which solves the problem that a light emitting element slightly emits light due to an off current of a thin film transistor connected in series to the light emitting element, and increases contrast in display, to achieve a clear display, and a driving method thereof.SOLUTION: When a thin film transistor 102 connected in series to a light emitting element 105 is selected to be turned off, a charge held in capacitance of the light emitting element 105 itself is discharged. Even when an off current is generated at the thin film transistor 102 connected in series to the light emitting element 105, the off current charges this capacitance until the capacitance of the light emitting element 105 itself holds a predetermined voltage again. Accordingly, the off current of the thin film transistor 102 does not contribute to light emission. In this manner, a slight light emission of the light emitting element 105 can be reduced.SELECTED DRAWING: Figure 1
