Abstract: An electroluminescent display device includes a display panel including a plurality of pixels each having a light emitting element and a driving thin film transistor for controlling a driving current flowing through the light emitting element and connected to a data line and a gate line, a panel driver connected to the data line and the gate line, and a timing controller configured to control an operation of the panel driver such that the operation is divided into an emission period in which the light emitting element emits light and a non-emission period in which light emission is stopped and to perform control such that a data voltage is input through the data line during the non-emission period and light emitting elements to which the data voltage is applied simultaneously emit light during the emission period.

Abstract: A display apparatus in one example includes a display panel having a subpixel configured to emit light with a data voltage applied through a first data line and change an emission condition, based on an additional voltage applied through a first additional line. The display apparatus further includes a driver configured to drive the display panel.
