AI Technical Summary

Problems solved by technology

When the size of the backlight module is larger, more spacers are required, resulting in a significant increase in assembly and material costs
In addition, the mold cost of the planar optical control board is high. If the mold area can be reduced, the cost can be saved and the product competitiveness can be improved.

Embodiment Construction

[0043] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments to further understand the objectives, solutions and effects of the present invention, but not as a limitation of the protection scope of the appended claims of the present invention.

[0044] figure 1 It is a schematic partial cross-sectional view of a backlight module according to an embodiment of the present invention. See figure 1 The backlight module 100 of this embodiment includes a reflective plate 110, a light source 120, a three-dimensional optical control structure 130, and at least one support structure 140. It should be noted that figure 1 Only one light source 120, one three-dimensional optical control structure 130 and two supporting structures 140 are schematically taken as examples in order to illustrate the relative positional relationship of the above-mentioned elements. Of course, the number relationship...

Abstract

The invention discloses a backlight module group comprising a reflector, a light source, a three-dimensional optical regulation and control structure, and a supporting structure. The light source is configured on the reflector. The three-dimensional optical regulation and control structure is configured on the reflector, and is used to cover the light source. The supporting structure is configured on the reflector, and comprises a column body, which passes through two parts of the three-dimensional optical regulation and control structure for the supporting of the three-dimensional optical regulation and control structure. By adopting the backlight module group provided by the invention, the costs can be reduced, the three-dimensional optical regulation and control structure can be reduced effectively, and the probability of deformation caused by the vibration, the falling, or the high temperature and high humidity environment can be reduced.

Description

Technical field [0001] The present invention relates to a backlight module, and in particular to a backlight module that can provide a lower cost and a stable structure. Background technique [0002] In recent years, with the widespread use of electronic products, display panels for providing display functions in electronic products have become the focus of attention of designers. There are many types of display panels, which can be selected according to the design of electronic products. Among them, some types of display panels do not have a light-emitting function, and a backlight module (backlight module) needs to be arranged below to provide a light source to achieve the display function. [0003] The backlight module usually includes an assembly frame, a light source, and a planar optical control board. According to the relative relationship between the light source and the planar optical control board, the backlight module can be divided into a direct type backlight module ...
