Description

Integrated projection optical display system of self-adaptive teaching display panel

Technical Field

The invention relates to the technical field of teaching display equipment, in particular to an integrated projection optical display system of a self-adaptive teaching display panel.

Background

At present, teaching display equipment mainly comprises a projector and a display panel, the projector is equipment capable of projecting images or videos onto a curtain, and can be connected with a computer, a VCD, a DVD, a BD, a game machine, a DV and the like through different interfaces to play corresponding video signals, the projector is widely applied to offices, schools and entertainment places, different types such as a CRT, an LCD, a DLP and the like are provided according to different working modes, the display panel is one of the most commonly used products in peripheral equipment of the projector, if the display panel is properly matched with the projector, a good-quality projection effect can be obtained, the liquid crystal display projector equipment is one of the most popular mainstream products at present, the working principle is that the projector utilizes the photoelectric effect of liquid crystals, namely the arrangement of the liquid crystal molecules and the state of the liquid crystal molecules are changed under the action of an electric field to influence the light transmittance or the reflectivity of the liquid crystal units, and the purpose of utilizing the principle to accurately control the light passing through the liquid crystal units can be achieved. The light source in the liquid crystal projector is a laser and led light source, emits bright white light, and is decomposed into RGB (red, green and blue) light rays through a spectroscope in an optical path system, the RGB light rays pass through liquid crystals at precise positions, each liquid crystal acts like a light valve at the moment, whether the light rays pass through each liquid crystal and the quantity of the light rays passing through the liquid crystal are controlled, and a colorful image which is consistent with a source image is formed on a display panel. And secondly, DLP projection adopts a digital micro-mirror device DMD chip as an imaging device, and realizes a projection technology of projecting an image by adjusting reflected light. It is very different from a liquid crystal projector, and its imaging is realized by reflecting light by thousands of tiny mirrors. From the technical point of view, the DLP projector mainly has three characteristics of high primary contrast, machine miniaturization and closed light path. In the foregoing, the DMD chip adopts a mechanical working mode, so that the controllability of the movement of the mirror is higher, and the original contrast is higher. The DLP projector adopts a reflection type principle, the realization of high aperture opening ratio is simpler, a DLP optical path system of a product with the same configuration is smaller, and the DLP projector can be smaller certainly. In addition, the DMD chip adopts a semiconductor structure, and the lens is not easy to change greatly when the DMD chip operates at high temperature, so that a closed light path is adopted by the DLP projector, and the probability of dust entering the DLP projector is reduced.

The following problems exist in the prior art:

the existing integrated projection optical display system of the self-adaptive teaching display panel is not stable enough to fix the projector, the projector is easy to fall off from a blackboard when being collided by the outside, the projector is damaged, the connection between the projector and the blackboard is not stable enough, and after long-time use, a projector support is deformed, so that the picture is deviated, the touch is invalid, and the picture definition is reduced; the existing integrated projection optical display system of the self-adaptive teaching display panel is inconvenient to adjust the horizontal position of the projector, the general projector is connected to a black and white board through a universal joint, the projector can only adjust the angle and display the image on a middle screen of the black board, the left screen or the right screen cannot be replaced at any time, if a display area needs to be replaced, the projector must be installed again, and the position adjustment is troublesome. The prior integrated projection optical display system of the self-adaptive teaching display panel is characterized in that a projection and a display panel are completely separated into two independent bodies which are not communicated with each other. And the construction and installation need to be separated and the control needs to be separated. The installation process is complicated, and control is single. The existing integrated projection optical display system of the self-adaptive teaching display panel needs to select mounting points of the projection and the display panel respectively, has requirements on the height space of the mounting environment, cannot be used in places with smaller height, has large limitation and small application scenes. The projection and display panel of the existing self-adaptive teaching display panel integrated projection optical display system are completely and independently installed, the central position between the projection and display panel can not be completely superposed, the projected picture is inclined and not centered, and the image is not clear;
