    • PROBLEM TO BE SOLVED: To provide a lighting system capable of improving diffusion or scattering performance of illumination light at a low cost, and a driving method of the lighting system.SOLUTION: The lighting system is provided with a light source, an optical element which diffuses or scatters light emitted from the light source, and a reflector which reflects the light passing the optical element toward the direction of the optical element. The light emitted from the light source is made to pass the optical elements several times and then is emitted as illumination light. Thereby, with a simple structure comprising the light source, the optical element, and the reflector, the performance of diffusion or scattering of illumination light emitted from the lighting system can be improved at a low cost.
    • 要解决的问题:提供能够以低成本改善照明光的扩散或散射性能的照明系统以及照明系统的驱动方法。 解决方案:照明系统设置有光源,漫射或散射从光源发射的光的光学元件,以及反射通过光学元件的光朝向光学元件的方向的反射器。 从光源发射的光使光学元件多次通过,然后作为照明光发射。 因此,利用包括光源,光学元件和反射器的简单结构,可以以低成本提高从照明系统发射的照明光的扩散或散射的性能。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a lighting unit of front light type capable of reducing deterioration of uniformity of intensity of light irradiated from a display device to a display section, and to provide the display device having this lighting unit.SOLUTION: The display device is provided with the lighting unit and a display section of reflection type. The lighting unit includes a translucent substrate, a plurality of light-emitting portions arranged dispersed on one surface of the substrate, and a first wiring and a second wiring connected to each light-emitting portion. The first wiring consists of a plurality of metal wiring extended in parallel, and the display section is arranged so as to be opposed to the one surface of the substrate.
    • 要解决的问题:提供一种能够降低从显示装置照射到显示部分的光的均匀性劣化的前光型照明单元,并提供具有该照明单元的显示装置。

      解决方案:显示装置设置有照明单元和反射型显示部。 照明单元包括半透明基板,分散在基板的一个表面上的多个发光部分,以及连接到每个发光部分的第一布线和第二布线。 第一布线由平行延伸的多个金属布线组成,并且显示部分布置成与基板的一个表面相对。 版权所有(C)2013,JPO&INPIT
