Image direct output device

Abstract

The invention discloses an image direct output device. The image direct output device comprises an outer shell, a light source set, a digital microchip device and a projecting lens. The light source set is provided with a light source, a light guiding column and a miniature lens set. The digital microchip device is used for collecting miniature light beams of the light source set and is provided with a stationary-type color wheel and a minitype reflecting mirror set. The stationary-type color wheel is used for conducting color separation and color filtering on the light source and is provided with a plurality of color blocks. The minitype reflecting mirror set is arranged on the side, different from the light guiding column, of the miniature lens set and is used for receiving the light source which is processed by the stationary-type color wheel. The projecting lens is used for receiving an output light source of the digital microchip device and enabling the output light source to be shot out of the outer shell. The image direct output device which can effectively lower needed cost and time is provided.

Description

technical field [0001] The invention relates to a direct output device, especially an image direct output device which can reduce manufacturing cost and time. Background technique [0002] With the rapid development of modern technology, the current digital image projection and display industry has evolved from the three-gun color projection technology with a huge size like a desktop in the early stage. So far, there are simple projectors and single-gun projectors that are as small as a mobile phone and can be carried around. High image quality and high brightness are suitable for lectures, presentations, or movie watching projectors and home-use large-screen high-contrast (Full HD 1080P) projection TVs, etc. The customer base of these digital image projection and display products also comes from a few specific companies The office needs instruments and gradually expands to household consumer electronics products, which are widely used in a large number of applications; [...

Problems solved by technology

[0005] Existing DLP or LCoS projection and display devices mainly perform color separation by rotating the color wheel, and then present colorful static and dynamic projection effects. However, limited by engineering technology and manufacturing costs, the existing color wheel is like Figure 9 The display is mainly through coating the required colors (such as R, G, B, etc.) on several glass substrates, and then cutting, collaging, and calibrating the balance according to the required size and shape. Therefore, the component structure of the existing color wheel is complicated, the weight is increased, and balance calibration is required to avoid the noise of the collage color wheel rotating at high speed, and because several substrates need to be pasted combined, so the penetration of the light source will be attenuated again;

[0006] Although there are a few high-end DLPs in the industry TM Compared with LCoS projection and display equipment, a single-chip color wheel is used. However, this kind of single-chip color wheel uses high unit price semiconductor lithography technology and equipment for protective layer photoresist coating, pattern mask, lithography exposure, Photoresist development, coating, etc. complete the first layer of color one by one. Such steps must be repeated continuously after required colors such as R, G, and B to complete a single-chip color wheel, so its manufacturing cost is almost higher than that of color filters for display panels. (Color Filter) price, relative to the cost of manufacturing and use, there is room for improvement
