  • Patent number: 10283072
    Abstract: A pixel circuit is provided which includes a data writing module, a drive module, a control module and an electrochromic device. The data writing module provides a data signal to the control terminal of the drive module under the control of a first control signal. The drive module drives the electrochromic device for color development or color fading according to a power supply voltage signal under the control of the data signal. The control module controls the conduction between the drive module and the electrochromic device on the basis of a second control signal, and the control module controls the conduction so that the conduction is realized later than the change in the power supply voltage signal. The pixel circuit effectively removes interference of the power supply voltage signal, avoids display fluctuations caused by the change in the power supply voltage signal, and further improves the display effect.
