Abstract
A display device includes a timing control circuit, a driving circuit, a display panel, and a DC voltage converter. The timing control circuit generates a data signal based on an image signal. The driving circuit generates a first conversion control signal and a second conversion control signal representing a status of the first conversion control signal. The driving circuit generates a driven signal based on the data signal and is powered by a first DC voltage. The display panel is powered by a second DC voltage. The DC voltage converter includes first and second DC voltage conversion circuits. The first DC voltage conversion circuit generates the first DC voltage based on an external voltage. The second DC voltage conversion circuit generates the second DC voltage based on the external voltage. The DC voltage converter executes time-shared control of the first and second DC voltage conversion circuits based on the first and second conversion control signals.
