US Patent 11804174 Display panel having even brightness, driving circuit, and driving method

Disclosed are a display panel, a driving circuit, and a driving method. The driving circuit includes multiple sub-pixels. For each sub-pixel, the sub-pixel includes: a light-emitting element; a pre-charging unit; a driving unit; and a detection unit. In condition of a detection operation being performed, the pre-charging unit is configured to receive the data driving signal, the driving unit is configured to generate a detection driving current, and the detection unit is configured to detect the detection driving current, such that the display panel determines and compensate a compensation signal; in condition of a display operation being performed, the pre-charging unit is configured to receive the compensated data driving signal, and the driving unit is configured to generate a display driving current to drive the light-emitting element to emit light.
