Abstract

The invention relates to a projection lens set and the vibrating device thereof. And the vibrating device comprises a light reflecting element, a bearing element, a base, at least a magnetic element and at least a coil circuit, where the light reflecting element is arranged on the bearing element; one surface of the base is vertically provided with at least a supporting element for supporting the bearing element and the light reflecting element; the magnetic element is arranged on the base and near one side of the light reflecting element and has a first polarity and a second polarity; the coil circuit is wound on the side of the light reflecting element, and as the current direction in the coil circuit changes, there is an attraction and repulsion between the light reflecting element and the magnetic element to vibrate the light reflecting element. Because the vibration of the light reflecting element displaces light path, it eliminates the picture incontinuity caused by gaps on the digital microlens in a projection system, by visual stay, thus more practical.

Description

technical field

[0001] The invention relates to a projection lens group and its vibrating device, in particular to a projection lens group and its vibrating device used in an image projection system. Background technique

[0002] Under the multiple demands of large display area, miniaturization and lightweight system, image projection system has become one of the most popular sub-items in the optoelectronic industry.

[0003] According to the principle of projection, the projection system can be divided into three major types, which are liquid crystal projection system (Liquid Crystal Display, LCD), single crystal silicon liquid crystal projection system (Liquid Crystal on Silicon, LCOS) and digital light source processor projection system (Digital Light Processing, DLP), among them, DLP has become one of the new generation of popular projection systems due to its advantages of high brightness, accurate tone reproduction, fast response time, no noise, and light and small. ...
