Abstract
A pixel circuit includes a driving transistor, a threshold compensation transistor, and a shielding layer. The threshold compensation transistor includes first and second sub-threshold compensation transistors. First electrode of the first sub-threshold compensation transistor is connected to gate of the driving transistor. Second electrode of the first sub-threshold compensation transistor is connected to first electrode of the second sub-threshold compensation transistor. Second electrode of the second sub-threshold compensation transistor is connected to first electrode of the driving transistor. Gate of the first sub-threshold compensation transistor and gate of the second sub-threshold compensation transistor are connected. Active layer of the threshold compensation transistor includes first sub-channel region, second sub-channel region, first connection region. The first sub-channel region at least partially overlaps the gate of the first sub-threshold compensation transistor. The second sub-channel region at least partially overlaps the gate of the second sub-threshold compensation transistor.
