The exemplary embodiments herein provide an electronic display having high brightness through continuation operation over a period of 5 to 10 years or more. High ambient temperatures do not affect the luminance output of the exemplary displays. Off angle viewing only affects the luminance output by the display minimally when compared to prior art electronic displays. The displays can produce at least 98% LED efficacy over the span of up to 15 years of continuous operation in an outdoor environment. Exemplary displays maintain at least 85% NTSC color saturation for up to 10 years of continuous operation in an outdoor environment.

A lighting device includes a light source line, a light guide plate, and a wavelength converting member. The light source line includes an inner light source and outer light sources. The inner light source is disposed in the middle and configured to emit primary light rays in a predefined wavelength range. The outer light sources are disposed outer than the inner light source and configured to emit primary light rays and complementary color light rays. The light guide plate includes a light entering surface and a light exiting surface. The wavelength converting member contains first phosphors configured to emit secondary light rays in a wavelength range different from the wavelength range when excited by the primary light rays. The wavelength converting member is disposed to cover the light exiting surface and configured to pass some of the primary light rays and to release planar light.

An image display apparatus is disclosed. The image display apparatus includes a display, a first speaker unit to output a first sound in a front direction, and a second speaker unit to output a second sound in a ceiling direction. The second speaker unit includes an array speaker with a plurality of speakers.
