A pixel circuit, an array substrate, a display panel and an electronic apparatus are provided. The pixel circuit includes: a data writing sub-circuit, a first data storage sub-circuit, a second data storage sub-circuit and a light-emitting control sub-circuit. The data writing sub-circuit writes, under the control of a signal input from a first control signal input end, to the first data storage sub-circuit a data signal input from a data signal input end, and writes, under the control of a signal input from a second control signal input end, to the second data storage sub-circuit the data signal input from the data signal input end. The light-emitting control sub-circuit controls on/off states of corresponding thin film transistors in accordance with data signals output from the first data storage sub-circuit and the second data storage sub-circuit, so that different gray-scales may be rendered.
