Abstract
A light-emitting panel and a display device are provided. The light-emitting panel includes a plurality of light-emitting components arranged in an array, a plurality of signal calculation modules, and a reference-signal generation module. A light-emitting component includes a light-emitting module and a first switch module. The light-emitting module and the first switch module are connected in series between a first power terminal and a second power terminal. A control terminal of the first switch module is connected to a signal calculation module, and the signal calculation module is connected to the reference-signal generation module. The reference-signal generation module is configured to generate a reference signal. The signal calculation module is configured to receive an original data signal and the reference signal, and generate a first data signal. The signal calculation module is further configured to generate a pulse width modulation signal, and to control the light-emitting module to emit light.
