A kind of 3D glasses and manufacturing method thereof

Abstract

The invention provides 3D (Three Dimensional) glasses and a production method thereof. The 3D glasses comprise glasses supports, two LCD (Liquid Crystal Display) lenses, a battery, a main PCB (Printed Circuit Board), a PCB connecting board, a first FPC (Flexible Printed Circuit) board and a second FPC board, wherein the first FPC board and the second FPC board are embedded into the glasses supports through an injection molding technology; the PCB connecting board is arranged inside a nose bridge position of the glasses supports and connected with the two LCD lenses; the battery and the main PCB are respectively arranged inside two free ends of the glasses supports and respectively connected with the PCB connecting board through the first FPC board and the second FPC board; and the PCB connecting board is provided with an electrostatic protection module. The 3D glasses have the advantages of being easy to perform machining and assembling due to the fact that the PCB connecting board, the first FPC board and the second FPC board are light in weight; avoiding wire welding and assembling difficulties and greatly reducing the oppressive feeling to a nose bridge when the 3D glasses are worn due to the fact that interconnected electrical performance is good; and simultaneously solving the LCD lens damage problem caused by electrostatic conduction due to the facts that the electrostatic protection module is placed on the PCB connecting board and capable of providing an electrostatic nearby access.

Description

technical field [0001] The invention relates to the technical field of 3D glasses, in particular to 3D glasses and a manufacturing method thereof. Background technique [0002] In traditional 3D glasses, the PCB board where the control circuit is located and the battery are installed in the nose bridge at the front end of the glasses bracket. This structure is relatively simple, but it is easy to wear the glasses because the bridge of the nose is always under great pressure during wearing the glasses. Causes nose bridge fatigue. At the same time, the PCB board is set in the bridge of the nose of the 3D glasses, and needs to be electrically connected to the battery, some control switches and function buttons in the temples through connecting wires, and the space of the glasses bracket is small, so this structure is difficult to assemble. Electrical connection performance is unstable. In addition, some 3D glasses place the PCB board and the battery on the two free ends of th...
