Embodiment Construction

[0010] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0011] Please also refer to Figure 1 to Figure 3 , the embodiment of the present invention provides a digital display device 100 . The digital display device 100 includes a light source 20 , a converging component 40 , a micromirror device 60 and a projection component 80 .

[0012] The light source 20 is a laser light source or an LED light source.

[0013] The converging component 40 includes two converging lenses 401 and 402 for converging the light emitted from the light source 20 .

[0014] The micromirror device 60 is used to control whether the light projected from the converging component 40 enters the display light path, so as to generate a digital display image.

[0015] The projection assembly 80 includes two projection lenses 801 and 802 for receiving digital images and projecting and displaying the digital images on a proje...

Abstract

The invention provides a digital display device. The device comprises a light source, a convergence component, a pair of micro mirror devices and a projection component, wherein the convergence component is used for converging light rays emitted from the light source; the pair of micro mirror devices are used for controlling the entry of the light rays projected from the convergence component into a display light path so as to produce a digital display image; and the projection component is used for receiving the digital image and performing projection display on the digital image. The micro mirror device in the digital display device is manufactured by a micro-electro-mechanical process and a CMOS process, has the advantages of small volume, light weight, low cost and the like, and is relatively suitable for displaying date or time in a small-sized hand-held mobile communication device.

Description

technical field [0001] The invention relates to a digital display device, in particular to a micro-electromechanical (MEMS) digital display device. Background technique [0002] At present, digital display devices generally use 7-segment LED digital tube display, which consists of 7 light-emitting diodes arranged in the shape of a "day". Some of the diodes are turned on, and the turned on diodes light up to form a number. However, such a structural design has a large volume and is not suitable for placing in a miniaturized handheld mobile communication device. Contents of the invention [0003] In view of this, it is necessary to provide a digital display device with a smaller volume. [0004] A digital display device, which includes a light source, a converging component that condenses the light emitted by the light source, a pair of micromirror devices that control whether the light that passes through the converging component enters the display optical path, thereby g...
