Abstract
The present disclosure provides a display driving circuit and a display device. The display driving circuit includes multiple pixel circuits. A data end of each pixel circuit is connected to a data line, configured to provide a data signal; a gate end of each pixel circuit is connected to a gate line, 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 multiple pixel circuits are divided into at least one first pixel circuit and at least one second pixel circuit, and a luminous efficiency of the first pixel circuit is less than that of the second pixel circuit; a width-to-length ratio of a channel of a thin-film field-effect transistor in a driving module of the first pixel circuit is greater than that of the second pixel circuit.
