Abstract
This display module performs a high quality display by preventing the effect resulting from a residual charge of a data signal in the previous scanning remaining in a capacitor of a pixel circuit.The display module is provided with the pixel circuit having an active element that selects a pixel by a horizontal scanning signal supplied from a scanning line GL every intersection unit of multiple scanning lines GLs arranged in a matrix within a display region AR on a substrate SUB, a data holding element that holds a data signal supplied from the data line by the turn-on of this active element, and an organic light emitting diode OLED that emits light by the current supplied from a current supply line CSL in accordance with the data signal held in the data holding element, and a reset circuit RST that recovers at least either a capacitor CPR or a data line DL of the pixel circuit to an initial condition is provided before data for the pixel that corresponds to the next scanning line is sent to the data line after the scanning of the scanning line before one is finished.
