Abstract
A light-emitting control signal generation circuit, a display panel and a display apparatus are provided. The light-emitting control signal generation circuit includes a first control module, an interlocking stabilization module, a second control module and an output module. The display panel includes a cascade circuit including a plurality of light-emitting control signal generation circuits, and the display apparatus includes the display panel. The light-emitting control signal generation circuit has a simple circuit structure with four modules coordinating one another, such that a signal outputted by a signal output terminal has a same pulse width as an effective pulse signal supplied to a signal input terminal. By adjusting the pulse with of the effective input pulse signal, the pulse width of the output signal may be adjusted accordingly, thereby fulfilling various display needs for different brightness of the display panel and improving quality and flexibility of display images.
