Embodiment Construction

[0069] Hereinafter, embodiments of the present invention will be described with reference to Examples and the accompanying drawings.

[0070] The flat panel display of the present invention is characterized in that it includes a space between the light guide unit and the diffusion plate. refer to Figure 2A , the light guide unit 201 is arranged between the reflector 202 and the diffusion plate 203 , and a panel 204 (eg, a liquid crystal panel) is arranged above the diffusion plate 203 . A distance 206 is located between the light guide unit 201 and the diffusion plate 203 . exist Figure 2B Among them, the light guide unit 201 is disposed between the reflector 202 and a plurality of optical components (diffusion plate 203 and polarizer 205 ). Likewise, the distance 206 is located between the light guide unit 201 and the diffusion plate 203 . A panel 204 is provided above the polarizer 205 . exist Figure 2C Among them, the diffuser 203 is arranged between the reflector ...

Abstract

A flat-panel display apparatus is provided to increase the color smoothness and brightness of the resultant image by enhancing the light emitted from a light guiding unit. The apparatus provides improved flat-panel display color uniformity from the light emanating from the light guiding unit. The apparatus comprises a gap disposed between the light guiding unit and a panel and its associated optical layers. The gap is located in a close proximity to the light guiding unit. Moreover, the flat-panel display apparatus further comprises a light transmissive plate disposed inside the gap.

Description

Technical field: [0001] The present invention relates to a flat-panel display technology and a light source device thereof, and to a display technology for controlling the color and light-emitting characteristics of an image. Background technique: [0002] In recent years, flat panel displays have attracted much attention due to their thinness and large size, and are gradually widely used in business or daily life. Flat panel display technology is commonly used in electronic products such as notebook computers, desktop monitors, televisions, digital cameras, DVD players, personal digital assistants (PDAs), cell phones, handheld games, and car navigation systems. In addition, the widespread application of flat-panel display technology has also stimulated the advancement of technologies such as color sensing methods and light source control. [0003] figure 1 A cross-sectional view of a conventional flat panel display 101 is shown, which has light sources 102 disposed on bot...
