Embodiment Construction

[0023] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0024] The present invention firstly provides an optical component, which includes a substrate, and also includes an optical waveguide structure located on at least one side of the substrate, the optical waveguide structure can refract incident light, so that the light is emitted along a predetermined direction; The optical waveguide structure includes a plurality of laminated light-transmitting layers for refracting light.

[0025] Optical waveguide is a guiding structure that transmits optical frequency electromagnetic waves composed of optically transparent media. The transmission principle of the optical waveguide is that the total reflection phenomenon of the electromagnetic wave confines the light wave to propagate in the waveguide and its surround...

Abstract

The invention provides an optical assembly and a display device. The optical assembly comprises a substrate, and further comprises an optical waveguide structure disposed on at least one side of the substrate. The optical waveguide structure can refract incoming light to make the light go out along a predetermined direction. The optical waveguide structure comprises multiple light transmission layers which are arranged in a stacked manner and used to refract light. The display device provided by the invention comprises the optical assembly provided by any embodiment of the invention.

Description

technical field [0001] The invention relates to the display field, in particular to an optical component and a display device. Background technique [0002] In an existing conventional liquid crystal display device, an optical gain film needs to be arranged above the light guide plate to achieve the desired brightness to the greatest extent. The optical gain film material currently used in the module, that is, the prism sheet, its upper surface is composed of microprisms with a pitch of several to tens of microns. This highly concentrating structure can maximize the vertical outgoing light. , but at the same time, its prism structure will concentrate the strong light in a certain direction into the human eye, resulting in glare. [0003] Glare refers to the visual condition that causes visual discomfort and reduces the visibility of objects due to inappropriate brightness distribution or extreme brightness contrast in space or time in the field of vision; the light feeling ...
