Abstract

The invention provides a light-emitting unit and a sideward light emitting type liquid crystal display with the light-emitting unit. The light-emitting unit comprises a first light-emitting assembly. The first light-emitting assembly comprises a substrate and an LED packaging body arranged on the first surface of the substrate. The light-emitting unit further comprises a second light-emitting assembly. The second light-emitting assembly comprises a transparent pipe and quantum dot material. The transparent pipe comprises pipe walls which include the arc-shaped inner wall and the arc-shaped outer wall, and a pipe cavity defined by the arc-shaped inner wall. The pipe walls extend in the direction parallel to the first surface. The side, facing towards the substrate, of the arc-shaped outer wall is in a wavy shape. The wavy shape is symmetrical with the perpendicular face, passing through the central light-emitting point of the first light-emitting assembly and perpendicular to the first surface, as the symmetrical face. The pipe cavity is formed along the symmetrical face. The quantum dot material is arranged in the pipe cavity. The side, facing towards the substrate, of the arc-shaped outer wall is in a wavy shape, and therefore the light receiving area of quantum dots is enlarged, the utilization rate of the quantum dots is increased, the luminous efficacy of the light-emitting unit is improved, and work stability of the quantum dots is improved.

Description

technical field [0001] The invention relates to the field of light-emitting devices, in particular to a light-emitting unit and a side-emitting liquid crystal display having the same. Background technique [0002] The color rendering principle of color display products (such as computer screens, TVs, smart phones, etc.) is based on the combination of blue, green and red "three primary colors". Filters come apart. Among them, the color gamut of the display is used to represent the ability of the display device to reproduce colors. The larger the color gamut of the display, the more colors the display can display, so that the displayed picture is richer and can reflect the color of the displayed image. reality of things. However, referring to the color television broadcasting standard (NTSC), the color gamut level of mainstream liquid crystal display devices (including flat panel display devices) currently on the market is only about 72%, or even lower. In order to achieve ...
