摘要： A display apparatus includes a display panel configured to display an image. A light guide plate is disposed below the display panel. The light guide plate has a light incident surface. A light source is disposed adjacent to the light incident surface of the light guide plate to generate first light. A light conversion layer is disposed between the light guide plate and the display panel to convert a wavelength band of incident light. An optical filter layer is disposed between the light guide plate and the light conversion layer to selectively transmit or reflect incident light.

摘要： A display device including a display panel driving unit configured to convert an image signal provided from an external device into a data signal such that an image is displayed on a display panel, and to output a first light control signal and a second light control signal. A backlight unit is configured to provide the display panel with a first color light and a second color light different from the first color light in response to the first light control signal and the second control signal. The display panel driving unit is further configured to determine a pulse width of each of the first light control signal and the second light control signal according to a color characteristic of the image signal.
