Light-emitting panel and display device

A display device, comprising:

• a display panel, including:
• a plurality of light-emitting components arranged in an array;
• a plurality of signal calculation modules;
• a reference-signal generation module;
• a first power terminal;
• and
• a second power terminal,
• wherein:
• a light-emitting component of the plurality of light-emitting components includes a light-emitting module and a first switch module, wherein the light-emitting module and the first switch module are connected in series between the first power terminal and the second power terminal;
• a control terminal of the first switch module is connected to a signal calculation module of the plurality of signal calculation modules, 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 according to the original data signal and a common potential;
• the signal calculation module is further configured to generate a pulse width modulation signal according to the first data signal and the reference signal, and to control the light-emitting module to emit light by controlling the first switch module using the pulse width modulation signal;
• the original data signal is an analog signal for characterizing image information of a display area corresponding to the light-emitting component;
• and
• the common potential is preset according to a voltage range of the original data signal.
