Problems solved by technology

However, since the package body of the light emitting diode is usually dripped onto the light emitting diode chip by dispensing and cured by heating, its surface is mostly an arc-shaped curved surface, which makes it difficult to control the uniformity of phosphor powder distribution in the p

Abstract

The invention provides a light guide structure, a backlight module and a manufacturing method thereof. The light guide structure includes a light guide plate, an optical converting element and an optical vapor barrier. The light guide plate is provided with a light receiving face. The chemical vapor barrier covers the light receiving face. The optical converting element is arranged on the light receiving face and between the light guide plate and the optical vapor barrier. The invention utilizes the optical vapor barrier to separate optical converting element and the external world, thereby preventing the optical converting element from being affected with damp. Thus, the reduction of the optical converting efficiency is decelerated.

Description

technical field [0001] The present invention relates to a backlight module, in particular to a light guide plate structure, a backlight module and a manufacturing method thereof. Background technique [0002] Liquid crystal display devices have been widely used in electronic products such as personal digital assistants, notebook computers, digital cameras, mobile phones, and liquid crystal televisions. However, since the liquid crystal display device is not self-illuminating, it needs a backlight module to have a display function. [0003] The liquid crystal display device is mainly composed of a liquid crystal panel and a backlight module. The liquid crystal panel mainly includes two transparent substrates and a liquid crystal layer, and the liquid crystal layer is disposed between the two transparent substrates. The light emitting surface of the backlight module faces the liquid crystal layer to provide the surface light source required by the liquid crystal panel, so th...
