Display driving circuit and display device

A display device, comprising a light-emitting display module and a display driving circuit;

• wherein the display driving circuit comprises a plurality of pixel circuits;
• a data end of each pixel circuit is connected to a corresponding data line, and the data end is configured to provide a data signal;
• a gate end of each pixel circuit is connected to a corresponding gate line, and the gate end is configured to provide a gate signal;
• and a power supply end of each pixel circuit is connected to a same power supply common line;
• the plurality of pixel circuits are divided into at least one first pixel circuit and at least one second pixel circuit, and a luminous efficiency of each of the at least one first pixel circuit is less than a luminous efficiency of each of the at least one second pixel circuit;
• a width-to-length ratio of a channel of a thin-film field-effect transistor in a driving module of each of the at least one first pixel circuit is greater than a width-to-length ratio of a channel of a thin-film field-effect transistor in a driving module of each of the at least one second pixel circuit.
