Common-gate transistor, pixel circuit, driving method and display

Abstract

The disclosure discloses a common-gate transistor, a pixel circuit, a driving method and a display, including: a first doped region, a second doped region, a third doped region, a fourth doped region and a fifth doped region; the second doped region, the third doped region, the fourth doped region, and the fifth doped region are indirectly communicated through the first doped region, and the second doped region, the third doped region, and the fourth doped region, the fifth doped region and the first doped region are hetero-doped respectively. The two transistors in the common-gate transistor share one gate doped region, i.e., the first doped region, which can not only save one gate doped region, but also can make the gates of the two transistors have the same electrical parameters, and then the cascode effect of the two transistors is more ideal.
