Embodiment Construction
[0015] specific implementation plan
[0016] The content proposed by the present invention will be described in detail below in conjunction with the accompanying drawings. figure 1 It is the basic structural diagram of the compact embedded micro-projection engine provided by the present invention:
[0017] The optical machine 10, the circuit board module 20 and the shielding cover 30 adopt a stacked structure to reduce the area. The circuit board module 20 includes a light source conditioning driver, a display panel controller and a video interface circuit. The pins 102 of the R, G, and B three-color light sources are directly welded on the circuit board module 20 . The radiator 103 is integrated with the housing of the optical machine 10, and the radiator 50 is separated from the housing of the optical machine 10 to install the light source. There is a heat conduction pad 40 between them to reduce thermal resistance, and the shielding cover 30 also serves as a cooling plate ...

The invention relates to a compact embedded micro-projection engine, comprising an optical engine, a circuit board module, a shielding hood, a heat conducting pad and radiator, wherein the optical engine and the circuit board module adopt a stepped structure; and a standard video interface, a power interface and a plug-in component interface are arranged on the circuit board module. The stepped structure is adopted, so that the sizeof the engine is reduced; the radiators with different connection modes are adopted, so that the radiating problem of the engine is improved; and a standard interface mode is adopted, so that modularized production of the micro-projection engine is realized. A circuit board module is provided with an optical sensor and a temperature sensor, so as to realize and ensure the white balance and the brightness of micro-projection engine devices. With the scheme provided by the invention the problems that in the conventional embedded micro-projection engine devices, the volume is large, the radiating is difficult, the modularization is not easy to realize and the white balance and the lightness are not stable are solved, and simultaneously the industrialization of a micro-projection engine product can be conveniently realized.
Description
technical field [0001] The invention relates to a projection engine, in particular to a compact embedded micro-projection engine. Background technique [0002] With the development of projection technology, its application is becoming wider and wider, and projection equipment tends to be more and more miniaturized in the application environment, or the projection module is embedded in the product equipment of related applications. For example, embedded in PAD, notebook, mobile phone and other portable terminals for use. It can be seen that the market for embedded micro-projection engines is huge, but at present, embedded micro-projection engines have defects such as large size, difficult heat dissipation, difficulty in modularization, unstable white balance and brightness, so it is not easy to industrialize. Contents of the invention [0003] The purpose of the present invention is to provide a compact embedded micro-projection engine, which can better solve the problems ...
