Patent ID: 11948508
Assignee: SONY SEMICONDUCTOR SOLUTIONS CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 9:
10. A display device comprising:
display elements arrayed in a row direction and a column direction in a two-dimensional matrix, wherein
each of the display elements includes a current-driven light emitting unit and a drive circuit for driving the light emitting unit,
the drive circuit includes a drive transistor and a capacitor,
the drive transistor has a first source/drain region to which a drive voltage is applied via a first feeder line and a second source/drain region connected to a first end of the light emitting unit, and is configured in such a manner that a current corresponding to a voltage held in the capacitor flows to the light emitting unit via the drive transistor,
the drive voltage is applied to the first source/drain region of the drive transistor after a voltage of the second source/drain region of the drive transistor is set in such a manner that a difference between the voltage of the second source/drain region of the drive transistor and the drive voltage is decreased,
a second end of the light emitting unit is connected to a second feeder line, and
the voltage of the second source/drain region of the drive transistor is set when a voltage higher than a voltage during normal operation is supplied to the second feeder line.
