Abstract

The invention relates to a pair of 3D (three-dimensional) glasses, in particular to an active 3D (three-dimensional) glasses driving device. The device comprises a controller, wherein the controller is connected with a memory, a video input interface and a 3D glasses driving unit, the controller is also connected with an asynchronous receiving/sending module, and the asynchronous receiving/sending module is connected with the video input interface and the 3D glasses driving unit. The multi-channel active 3D glasses driving device has the advantages that received serial data is converted into parallel data through the asynchronous receiving/sending module, in addition, the odd-even tags are added, and during the output, the parallel data with the odd-even tags is converted into serial data to be output, so the asynchronous transmission is realized, the smooth and complete operation of the video data is realized, and the occurrence of stagnation and frame skip is avoided.

Description

The 3 D active eyeglasses drive unit of asynchronous communication

Technical field

The present invention relates to the 3D glasses, especially a kind of 3 D active eyeglasses drive unit.

Background technology

3 D active eyeglasses is important part of 3D Display Technique.General by a 3D glasses driving device or title driver, coordinate active shutter 3 D glasses to use.This 3D technology is applied the most extensively at TV with above projector, resource is relatively many, and image effect is outstanding, is subject to a lot of manufacturers and praises highly and adopt.Active-shutter 3D realizes 3D effect by the refresh rate that improves picture, by image is divided into two frame by frame, form two a series of paintings faces of corresponding left eye and right eye, interlock and show continuously, Infrared Projector, by the left and right eyeglass switch of Synchronization Control shutter type 3 D spectacles, makes left and right eyes see respective picture in the correct moment simultaneously.This technology can keep the original resolution of picture, allows very like a cork the user enjoy real full HD 3D effect, and can not cause picture brightness to reduce.

Because parallel processing is carried out when data are processed adopting in existing 3D glasses driving device inside, and usually adopt serial data interface while with data source, with the 3D glasses, being connected, because serial data interface is to store data in memory the then mode with first-in first-out to export, the picture stagnation easily appears when data volume is larger, the situations such as frame-skipping, affect user's normal use.

Summary of the invention

The invention provides a kind of broadcasting of carrying out video of smoothness, avoid stagnating the 3 D active eyeglasses drive unit of the asynchronous communication that the frame-skipping situation occurs.

To achieve these goals, the present invention adopts following technical scheme:

Preferably, described controller also is connected with the universal input/output interface module.

Preferably, described controller also is connected with power module.

Preferably, described controller also is connected with infrared receiving module.

Preferably, described controller also is connected with the WatchDog Timer module.

Preferably, described 3D power module output voltage is 3V-6.5V.

Preferably, described universal input/output interface module clock comprises 4 interfaces.

Preferably, described memory is OTP ROM memory.

Preferably, described 3D glasses driver element is built-in 10V driver module.

Preferably, described controller frequency is 4MHz.

Owing to having adopted said structure, multichannel 3 D active eyeglasses drive unit of the present invention converts the serial data of reception parallel data to and adds parity flag by asynchronous reception/sending module, during output, the parallel data of tape parity mark is converted to serial data output, thereby realize asynchronous transmission, realize the complete operation of smoothness of video data, avoid stagnating and the generation of frame-skipping situation.
