Problems solved by technology

[0003] 1. Commonly used video tube (CRT), liquid crystal (LCD) or plasma (TFT) screens will generate more or less radiation, which will affect human health
[0004] 2. Commonly used image tube (CRT), liquid crystal (LCD) or plasma (TFT) screens all use display light spots to form images, that is, direct stimulation of light spots to the eyes (ball) is easier for the operator Fatigue and even damage to eyesight
[0005] 3. When manufacturing commonly used traditional screens, the manufacturing process and the disposal of screens after they are discarded have had adverse effects on the green earth environment and sequelae
[0006] Due to the above-mentioned shortcomings of the commonly used screens, the eyesight and health of people who operate computers on the screens for a long time will be adversely affected. getting worse

Embodiment Construction

[0023] Please refer to figure 1 As shown, the projection computer of the present invention mainly outputs digital image display signals to a digital DVI card (Digital Visual Interface, digital character) by the CPU module (including the central processing unit, peripheral chips (Chipsets) and storage) 11 of the host computer 10. display interface card) 12, after coating and array operation, it is introduced into the liquid reflective semiconductor (Reflective Liquid Crystal On Silicon, LCOS) 31 in the projector 30 by the transmission method of the cable 20 for development, refraction, projection, and then passes through The operation of the light source 32 and the lens group 33 directly projects the image on the small area (about 40 cm) projection board 40, display screen or wall with strong light.

[0024] Although a general desktop computer (Desktop computer) or a notebook computer (Notebook computer) can be combined with a general projector to project images on the display ...

Abstract

A projection computer is composed of main computer, projector and projecting plate, which utilizes DVI card in main computer to export image signal being directly transmitted to LCOS (Reflective liquid crystal On silicon) of the projector for displaying and furthermore to be lightened by the optical source and amplified through lens set for being projected on the wall or on the projecting plate to replace the existing structure of displaying image with screen (Monitor).

Description

technical field [0001] The present invention relates to a computer structure, in particular to a projection computer which directly projects images on a wall or a projection board without configuring a common screen. Background technique [0002] The commonly used computer mainframe (mainframe) must be connected to the screen to display its operating status. However, the structure of using the screen has the following disadvantages: [0003] 1. Commonly used video tube (CRT), liquid crystal (LCD) or plasma (TFT) screens will generate more or less radiation, which will affect human health. [0004] 2. Commonly used image tube (CRT), liquid crystal (LCD) or plasma (TFT) screens all use light spots to form images, that is, it is easier for operators to directly stimulate the eyes (ball) with light spots. Fatigue can occur and even damage eyesight. [0005] 3. When manufacturing commonly used traditional screens, the manufacturing procedures and the disposal of screens after t...
