TWI278235B - Folding-type front-projection and back-projection dual-function TV and conveying method of back projection TV - Google Patents

Abstract

The invented projection TV is basically composed of a foldable reception housing and a projector body. The housing is provided with at least one projection display screen that can be disassembled and a speaker; and the accommodation body, which can be folded-and-received and pulled-and-extended, is provided at the backside of the housing. The accommodation body is used as the arrangement space for the projector body and the related optical devices. Thus, a dual-function TV can be formed, in which the projector body can be placed inside the housing to form back-projection or placed outside the housing to form front-projection. In addition, the housing can be folded and received such that it is convenient for conveying and accommodation.

Description

1278235 V. INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a unit structure improvement of a projection television, and aims to provide an image that can be projected from the inside of the casing to the back of the projection display screen or external to the casing. The dual-purpose projection TV that projects the image onto the front of the projection display screen; in particular, the casing can be folded and folded to facilitate the handling and storage of the projection television. [Prior Art] Press, generally used in conference rooms or home theaters to see the projection (FP) audio-visual equipment, mainly to connect the video signal to a projector (or projector), the projector converts the image signal into an optical projection image. The display screen projected by the projector is displayed by a display screen other than a certain distance, so as to achieve the effect of the large screen by using the amplification of the optical image. Moreover, the machine and the display complete the image; therefore, when the front optical image of the inner casing is used for electrical power, any displayable screen can be used as the image frame of the light-receiving image. Line cross • ~ 邛 公口人 I can block the shadow, and create the optical shadow back projection electric 'through the performance of the large screen image of the machine, the opposite view of the audience before the projection (screen must be excluded) There is also a video TV in the studio (or set a projection distance of the projection, the projection TV can be better integrated in the machine often needs to be used in the actual use of the image-like object to use the device group), the main The air image inside the shell expresses the effect of the projection path, and the projection electric front projection viewer, so that the projection body can be limited in a casing to be connected between the machine and extend the fruit. Put the equipment in the projection TV

χ 278235 ^ V. Invention Description (2) Before the replacement of the case, the light and the overall projection of the casing, the same will be used, R τ ) TV is effective, but the traditional cathode is expensive, not the film and television equipment. However, the conventional projection $ visual imaging device integration becomes an immutable solid knot. The volume is proportional to the image scale that can be presented. The volume is cumbersome, not only difficult to transport, but also takes up considerable indoor space. Although the plasma TV or the traditional cathode ray can be enlarged in size, when the size of the large screen image exceeds 4 〇, the overall electric ray tube (CRT) will be more cumbersome and the cost is generally The family can accept. The system will use the configuration and will not make ^ (C video table TV or equivalent) [invention] The present invention "television of the TV's overall projection TV foldable folding or machine and according to the machine Inside the shell, the projector will be single-projection display screen, especially in the unit, and will be removed. The folding method is used to produce the projection of the projector housing. The uranium projection and backing of the casing is made up of a single unit that can be cast by a single optical projection into a fixed sealing element, and the front part of the image is projected into the casing. The folding and folding, when not in use, the projection dual-use TV and the rear projection独 The single-operation projector unit is used as the image device, and the casing with the two closed body is used as the projection space. The relevant optical components are placed in the pull-up to the back of the projection display screen, or by the casing. Externally projecting the image L ' can facilitate the carrying of the projector inside the casing and accept the I278235

In addition, the group of projection TVs can also be applied to any of the commercially available labels of the north=pieces, which are modularized, mass-produced, disassembled, and transported, and are particularly advantageous for transport wheels. The cost. Appropriately, the manufacturing, storage, and [implementation] can be greatly reduced. In order to enable the operation mode of the body, the "projection television base can be used alone to produce the optical housing 2" as the capacitive element 11 machine. Shell 2 0, , the configuration of the housing of the closed body of the casing 20 is empty and the review committee cooperates with the diagram of the folding front-projection structure to form a detachable projection image device. The first part of the front side of the front side is provided with a body, and is accommodated by the room. f Chu The structure of the invention is as follows: ~ and the moon projection dual-use television", as shown in the first figure and the second figure, The unit 1 is used as a whole projection, and has a foldable body 10, a speaker 3 and a phase diagram, a second diagram and a third diagram, and a detachable projection display for folding or folding. The pull-up body is used as the projector unit and the phase and the whole body is made up of a TV unit. The front screen 2] fixed I off the light a. In the specific implementation, the casing 20 will project the display screen. 2 a front shell plate 2 2, and in front The four sides of the plate 2 2 are disposed, and the side plates 2 3 of the front cover plate 2 2 are folded and folded, and the cover plate 2 4 can be oriented toward the end of the cover plate 24 and the bottom plate of the folding bottom plate 2 5 Between _f ^ 2 5, the side plate 2 3, the cover plate 2 4, the bottom plate 2 5 and the front cover plate 2 6 suction 2
