Abstract: A display device includes a lower cover; a circuit substrate disposed on the lower cover; a plurality of light sources disposed on the circuit substrate; a reflection layer disposed on the circuit substrate; a light regulator disposed at an edge of the reflection layer at an angle with respect to the reflection layer; and an optical sheet disposed on the plurality of light sources. Further, the light regulator includes a reflector portion reflecting light from the plurality of light sources; and an absorber portion having holes arranged in a pattern. In addition, light emitted from a respective light source close to the edge passes through the holes.

Abstract: A lighting apparatus and a mobile terminal controlling the same are disclosed. The lighting apparatus comprises a light source module generating light; and an electrochromic module varying a wavelength of light incident from the light source module, wherein the electrochromic module absorbs light of a specific one among wavelength ranges of the light incident from the light source module, in accordance with a lighting mode which is input. The mobile terminal controlling a lighting apparatus, which includes a light source module and an electrochromic module, comprises an input module receiving a user input; a communication module transmitting a lighting control signal to the lighting apparatus; a display module displaying a setup window for setting a lighting mode of the lighting apparatus; and a controller controlling the input module, the communication module and the display module.
