Display front housing and manufacturing method thereof

Abstract

The invention discloses a display front housing. The display front housing comprises a transparent panel (1), a decorative layer (6) arranged around one side of the panel, and a face frame (2), wherein the face frame (2) is connected with the panel (1) into a whole by injection molding, and the decorative layer (6) is positioned between the joint face between the panel and the face frame. The invention also discloses a manufacturing method of the display front housing. The display front housing has the advantages of high light transmission of the panel, safe and reliable connection between the panel and the face frame, certain three-dimensional (3D) effect of the decorative layer seen out of the transparent panel, low cost, simple process, short manufacturing cycle, high yield and reliable quality and leads an inevitable development trend of the modern LED displays.

Description

technical field [0001] The invention relates to a display casing, in particular to a front casing suitable for a flat panel display and a manufacturing method thereof. Background technique [0002] Existing flat panel display front housings have a transparent panel on their front side. There are two production methods for the front shell. One method is: use injection molding or extrusion molding equipment to make a transparent panel first, and then decorate the side of the transparent panel with silk screen or spraying after cutting and grinding, and then the panel It is fixed on the display frame by glue or screws. Another method is: directly use two-color injection molding equipment, first inject a transparent panel, and then inject the surface frame on the transparent panel. [0003] The defect of the front shell made by the first method is: the panel and the surface frame are glued manually, which not only requires a lot of people to paste, but also the process is diff...

AI Technical Summary

Problems solved by technology

[0003] The defect of the front shell made by the first method is: the panel and the surface frame are glued artificially, which not only requires a lot of people to paste, the process is difficult to control, but also not firm, resulting in low product qualification rate and high scrap rate

The defects of the front shell made by the second method are: high mold development cost, many molding defects, complex injection molding process, and low product qualification rate

In particular, transparent panels cannot be decorated delicately. For example, if you want to screen-print colorful patterns on the side of the panel, especially the trademark, it cannot do it. It can only silk-screen the trademark pattern on the front of the panel. Such patterns can be touched by hands. , easy to wear and not environmentally friendly

Both of the above two production schemes have a fly in the ointment, and neither can make the panel side decoration effect embedded in the panel and surface frame materials and display it in front of consumers with a three-dimensional effect
