Abstract
Provided are a pixel circuit, a silicon-based display panel, and a display device. The pixel circuit includes a pixel drive circuit and a pixel compensation circuit; the pixel drive circuit includes a drive transistor and an organic light-emitting element; the drive transistor includes an output terminal and a body terminal, where the output terminal is connected to an anode of the organic light-emitting element, and the body terminal is connected to a body signal input terminal and configured to receive a body potential inputted from the body signal input terminal, the body potential being fixed; and a cathode of the organic light-emitting element is connected to the pixel compensation circuit at a first node, a potential of the first node is a cathode potential, and the cathode potential Vcom, a crossover voltage Voled of the organic light-emitting element, and the body potential Vbody satisfy that Vcom+Voled>Vbody.
