Problems solved by technology

Since the general light source emits non-polarized light, it means that at least half of the light intensity will be lost through the polarizer, which not only reduces the display brightness but also wastes electric energy

Abstract

The disclosure relates to a light emitting device. The light emitting device includes an insulative transparent substrate, a light emitting material layer, and a metal metamaterial layer. The metal metamaterial layer is located between the insulative transparent substrate and the light emitting material layer. The metal metamaterial layer includes a number of periodically aligned metamaterial units. Because the plasmon of the metamaterial can control electromagnetic properties in nanoscale, light from the light emitting device can be polarized in nanoscale. Thus, the light emitting device can emit polarized light. The display device using the light emitting device is also provided.

Description

Technical field [0001] The invention relates to a light-emitting device and a display device using the light-emitting device, in particular to a metamaterial plasmon integrated light-emitting device and a display device using the light-emitting device. Background technique [0002] Currently, liquid crystal displays have been widely used. The principle adopted by the liquid crystal display is to use an electrical modulation layer, such as liquid crystal molecules, to change the polarization of incident polarized light, so that the light intensity that finally passes through the analyzer changes. [0003] In order to generate polarized light, the currently widely used method is to use thin-film polarizers to polarize the light from the light source (tube or LED). Since the general light source emits unpolarized light, this means that at least half of the light intensity is lost through the polarizer, which not only reduces the display brightness but also wastes electrical energy. ...
