Light source device with high luminescent efficiency and manufacturing method thereof

Abstract

The invention provides a light source device and a manufacturing method thereof. The light source device comprises a cup base, a luminescent chip and a package body, wherein, the cup base is providedwith an accommodating space which is encircled by the cup wall; the luminescent chip is arranged in the accommodating space encircled by the cup wall; and the package body is filled in the accommodating space and encircles the luminescent chip. The outside surface of the package body mainly comprises two parts like a central concave side and an annular convex side, wherein, the annular convex sideencircles outside the central concave side to form an annularity; the central concave side forms a continuous concave ball cambered surface with no singular points; and the joint position of the central concave side and the annular convex side extrudes outside and forms an annular convex ridge.

Description

technical field [0001] The invention relates to a light source device and a manufacturing method thereof; in particular, the invention relates to a light source device and a manufacturing method thereof which can avoid excessive concentration of light and increase the efficiency of light use. Background technique [0002] The display panel and the panel display device using the display panel have gradually become the mainstream of various display devices. For example, various panel displays, flat-screen TVs for home use, flat-panel monitors for personal computers and laptops, display screens for mobile phones and digital cameras, etc., are all products that use a large number of display panels. In particular, in recent years, the market demand for liquid crystal display devices has grown significantly. In order to meet the functional and appearance requirements of liquid crystal display devices, the designs of backlight modules used in liquid crystal display devices are also...

AI Technical Summary

Problems solved by technology

However, in this traditional design, it is easy to focus the light on the front of the component

When used in conjunction with a backlight module, this characteristic of light concentration is likely to cause local bright spots in the backlight module, affecting the image quality of the display device

In addition, since the center point of the convex surface of the encapsulant 30 is relatively prominent, it is easy to contact with the light guide plate or other components and deform, thereby affecting the output performance of the light source.
