A display device includes an emission circuit, a first control circuit and a second control circuit. The emission circuit is coupled to a first node and is configured to emit light based on an emission signal and a voltage level of the first node. The first control circuit is configured to charge the first node based on a sweep signal and the emission signal. The second control circuit is configured to discharge the first node based on the sweep signal and the emission signal.

Display device

A display panel and a pixel circuit thereof are provided. A pulse width signal generator turns on a charge sharing switch during a light-emitting period, and performs charge sharing with a control end of a positive feedback switch of a positive feedback circuit, so as to control the positive feedback switch to provide a positive feedback voltage to the pulse width signal generator to increase a voltage at an output end of the pulse width signal generator and thus to accelerate a rising speed of a voltage for controlling a driving current generator to provide a driving current.

Display panel and pixel circuit thereof

A sweep voltage generator and a display panel are provided. The sweep voltage generator includes an output node, a current generating block and a voltage regulating block. The output node is used to provide a sweep signal. The current generating block is coupled to the output node, includes a detection path for detecting an output load variation on the output node, and adjusts the sweep signal provided by the output node based on the output load variation. The voltage regulating block is coupled to the output node for regulating a voltage of the output node.
