Patent ID: 11605336

Abstract:
A display panel and a display device are provided. The display panel includes a pixel circuit and a light-emitting element. The pixel circuit includes a data-writing module, a driving module including a driving transistor, and a compensation module. The driving transistor includes a source, a gate, an active layer, a first drain and a second drain, and is divided into first and second driving portions having channel regions with lengths of L1 and L2, respectively. The data-writing module is connected to the source, the compensation module is connected between the gate and the first drain, and L2/L1ΔVsd2/(ΔVsg+V0)−1, 0V0ΔVgd2×½; alternatively, the data-writing module is connected to the first drain, the compensation module is connected between the gate and the second drain, and L1/L2ΔVsd2/(ΔVgd2+V0)−1, 0V0ΔVsg×½.
