Abstract: A display device includes a display panel which includes pixels arranged in a matrix form and a controller which receives a first image signal corresponding to a first active period of a first frame, outputs a first final output signal corresponding to a first conversion active period of the first frame, and drives the display panel based on the first final image signal. The controller includes a timing changing unit which receives the first image signal and changes a first image signal pixel size corresponding to the first image signal to a panel pixel size corresponding to the display panel to generate the first output signal, and a frequency changing unit which receives the first output signal from the timing changing unit and reduces a frame frequency of the first output signal based on the first image signal to output the first final output signal.

Abstract: A display device includes lower and upper substrates facing each other, a light source which emits a light toward a side surface of the lower substrate, and an optical medium layer between the lower and upper substrate and through which the light transmits to generate an image. The lower substrate includes a first substrate within which the light travels from the side surface of the lower substrate to exit from an upper surface of the first substrate, and light exit patterns on the upper surface. The first substrate includes an incident surface to which the light emitted from the light source is incident. Each of the light exit patterns is in contact with the upper surface of the first substrate and respectively defines a first space between the light exit pattern and the upper surface of the first substrate, the first space being filled with air.
