Abstract
An electronic is provided. An input unit provides a multimedia content. An image processor transforms the multimedia content into frame data. A display unit displays images including blue pixels, green pixels, and red pixels. A backlight unit generates a source light. A source light includes a deep blue-light of a low blue waveband and a far blue-light of a high blue waveband. A display panel transforms the source light into the images based on the frame data and emits the images through a surface. An optical path travels through the backlight unit and the surface. A deep blue-light filter is arranged in the optical path through which the source light passes, for restricting a light transmission rate in the low blue waveband. The image processor adjusts a color hue of the frame data to be transformed by the display panel.
