Description
Technical Field
The invention relates to the technical field of teaching display equipment, in particular to a self-adaptive teaching display panel integrated projection optical display system.
Background
At present, the teaching display device mainly comprises a projector and a display panel, the projector is a device capable of projecting images or videos onto a curtain, corresponding video signals can be played through connection of different interfaces with computers, VCD, DVD, BD, game machines, DV and the like, the projector is widely applied to offices, schools and entertainment places, according to different working modes, different types of CRT, LCD, DLP and the like are adopted, the display panel is one of the most commonly used products in peripheral devices of the projector, if the display panel is matched with the projector properly, a high-quality projection effect can be obtained, the liquid crystal display projector device is one of the most popular mainstream products at present, the working principle is that the projector utilizes the photoelectric effect of liquid crystal, namely the arrangement of liquid crystal molecules and the state of the liquid crystal molecules change under the action of an electric field, the light transmittance or the reflectivity of a liquid crystal unit are influenced, and the projector can achieve the aim of accurately controlling light rays passing through the liquid crystal unit by utilizing electric signals by utilizing the principle. The light source in the liquid crystal projector is a laser and led light source, emits bright white light, and splits the white light into three element colors of RGB (red, green and blue) light through a spectroscope in an optical path system, wherein the three element colors of RGB light pass through liquid crystals at accurate positions, each liquid crystal acts like a light valve door at this time, whether the light passes through each liquid crystal and how much light passes through each liquid crystal are controlled, and a colorful image consistent with a source image is formed on a display panel. Secondly, DLP projection uses a DMD chip of a digital micromirror device as an imaging device, and a projection technique of projecting an image is realized by adjusting reflected light. It differs significantly from a liquid crystal projector in that its imaging is achieved by reflecting light through thousands of tiny mirrors. From the technical point of view, the DLP projector mainly has three characteristics of high original contrast, machine miniaturization and closed optical path. In the foregoing, we mention that the DMD chip adopts a mechanical operation mode, and the movement controllability of the lens is higher, so that the higher native contrast is just in mind. The DLP projector adopts a reflection type principle, so that the high aperture ratio is simpler to realize, the DLP light path system of the product with the same configuration is smaller, and the DLP projector can be smaller. In addition, the DMD chip adopts a semiconductor structure, and the lens is not easy to change too much when operating at high temperature, so that the DLP projector adopts a closed light path, and the probability of dust entering is reduced.

The existing self-adaptive teaching display panel integrated projection optical display system is characterized in that a projection and a display panel are completely divided into two independent individuals, and the two independent individuals are not communicated with each other. And the construction and the installation are required to be separated, and the control is required to be separated. The installation procedure is complex and the control is single.

As shown in fig. 1-6, when the laser and led light source projector 2 on the L-shaped inserting plate 41 is required to be installed in the installation seat 3, the L-shaped inserting plate 41 is inserted into the installation seat 3, the turning knob drives the bi-directional threaded rod 44 to turn, the bi-directional threaded rod 44 drives the sliding plate 45 to move, the sliding plate 45 drives the sliding rod 46 to move, the sliding rod 46 drives the tooth-shaped anti-slip block on the clamping plate 47 to be tightly adhered to the outer wall of the L-shaped inserting plate 41, the L-shaped inserting plate 41 is fixed, the L-shaped inserting plate 41 is prevented from shaking, so that the laser and led light source projector 2 is stably installed on the display plate 1, the laser and led light source projector 2 and the display plate 1 are integrated, the led light source projector 2 is projected on the display plate 1, the integrated equipment of touch-control integrated interactive teaching is achieved through infrared, capacitance, image optics and acoustic touch control, the arranged universal joint 42 can enable the laser and led light source projector 2 to reversely rotate to each other, the laser and the led light source projector 2 are convenient to fold and store, when the L-shaped inserting plate 41 is inserted into the mounting seat 3, the V-shaped inserting block 481 is inserted into the rubber base 43 to further stabilize the L-shaped inserting plate 41, when the laser and the led light source projector 2 are collided, the laser and the led light source projector 2 enable the L-shaped inserting plate 41 below the universal joint 42 to shake, the L-shaped inserting plate 41 drives the V-shaped inserting block 481 to shake, the V-shaped inserting block 481 drives the extrusion bar to extrude the honeycomb rebound frame 484, the honeycomb rebound frame 484 drives the extrusion block to extrude the first marble 485, the honeycomb rebound frame 484 deforms to extrude the sponge ring 486, the sponge ring 486 deforms to drive the two conical inserting bars 483 to move, the two conical inserting bars 483 are inserted into the rubber base 43, the L-shaped inserting plate 41 shakes, the depth of the conical inserting bars 483 inserted into the rubber base 43 is deeper, thus, the more stable the fixing of the L-shaped inserting plate 41 is, the laser and the led light source projector 2 on the L-shaped inserting plate 41 are not easy to fall from the display panel 1, when the sponge ring 486 deforms, the spring connector 488 and the second marble 489 are extruded, the follow-up sponge ring 486 can be convenient to recover, the sponge ring 486 drives the conical inserting strip 483 to recover, when the projection positions of the laser and the led light source projector 2 are required to be adjusted, the starting motor 55 drives the threaded rod 52 to rotate, the threaded rod 52 drives the door-shaped sliding block 53 to move, the door-shaped sliding block 53 drives the mounting seat 3 to move, and therefore the positions of the laser and the led light source projector 2 above the mounting seat 3 are adjusted, so that the laser and the led light source projector 2 can be projected onto a left screen or a right screen, and the advantage of convenient adjustment is achieved.
The foregoing invention has been generally described in great detail, but it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, it is intended to cover modifications or improvements within the spirit of the inventive concepts.
