DISPLAY DEVICE AND ELECTRONIC EQUIPMENT

WIPO Patent Application WO/2023/079404

A1

Provided is a display device with little chromaticity variation and good gradation control characteristics. This is a display device capable of carrying out PAM and PWM control (pulse width control involving changes in amplitude) on light emitted by a light emitting device, and capable of improving control characteristics on the low-gradation side while minimizing the amount of variation in chromaticity. The display device has a pulse signal generation unit and a light emission control unit in each pixel, and after the light emission control unit has been charged to a signal potential, can cause the signal potential to be discharged in response to a pulse signal generated by the pulse signal generation unit. Consequently, a light emitting device can be caused to emit light for a desired period of time at a desired light emission intensity.
