Abstract

The utility model relates to a large screen display device. The visual effect is enhanced. The utility model comprises a case. The inner side of the lower part of the case is provided with a concave focusing reflecting mirror, and a focal position of the concave focusing reflecting mirrors is provided with a bulb. The front of the bulb is provided with a light collecting lens and a plastic ophthalmic lens. The case at the front of the plastic ophthalmic lens is provided with a groove. The inner surface at the other end of the case forms an L shape through two reflecting mirrors. A pancratic lens is arranged above the case. An LCD screen is arranged in the groove, which has the function of transparency. The LCD screen is connected with a computer. Light source of the bulb passes through the LCD screen and becomes a refracting projection through two reflecting mirrors via the light collecting lens and the plastic ophthalmic lens, which is used for messages.

Description

Accurate liquid crystal data projector

The utility model relate to utilize the optical projection principle in conjunction with computer to reach the device of large screen display.

The liquid crystal projector of one of existing large screen display device promptly is commonly called as single rifle projector, its shortcoming be price height, projection brightness not enough, must purchase a computer in addition and be used, and can not use traditional transparency; Another kind has the portable computer of projecting function, its back panel of liquid crystal display partly is removable, can make this LCD Panel as can place it in that head is gone up as the lantern slide or projector on, connect image projection on screen by a transmission line, advantage is that computer can be dual-purpose, expense is lower, but shortcoming is a following formula projector heaviness and inconvenience is carried, and must better projection quality just be arranged at dark surrounds.

The purpose of this utility model provides the accurate preferably liquid crystal data projector of a kind of giant-screen visual effect.

The purpose of this utility model is achieved in that accurate liquid crystal data projector, it is characterized in that: it comprises a housing, inboard, housing below is provided with a spill focusing mirror, and establish a bulb in its focal position, and adorn a collector lens and glass lens in bulb the place ahead, establish a groove on the housing of glass lens the place ahead, housing holds inner face to be set as the L type with two catoptrons in addition, and a pancratic lens is established in the housing top; Adorn a liquid crystal display screen with transparency function in the groove, and this liquid crystal display screen connects computer.

Above-mentioned design, the light source of bulb is through collector lens and glass lens, see through liquid crystal display screen and be the refraction projection refraction projection backward that image can be made progress again after via two catoptrons, make image through being located at the pancratic lens of housing top, must with the image projection of liquid crystal display screen on projection screen, reach giant-screen visual effect purpose preferably.

Below by accompanying drawing, embodiment the utility model is described further again.

Fig. 1 the utility model stereographic map;

Fig. 2 the utility model cross-sectional schematic;

Another embodiment cross-sectional schematic of Fig. 3 the utility model.

As shown in Figure 1, 2: the utility model comprises a housing 1, inboard, housing 1 below is provided with a spill focusing mirror 2, and establish a bulb 3 in its focal position, and adorn a collector lens 4 and glass lens 5 in bulb 3 the place aheads, establish a groove 11 on glass lens 5 the place ahead housings 1, housing 1 holds inner face to be set as the L type with two catoptrons 6,6 ' in addition, and a pancratic lens 7 is established in housing 1 top; Adorn a liquid crystal display screen 8 with transparency function in the groove 11, and this liquid crystal display screen 8 connects computer, the light source of bulb 3 is through collector lens 4 and glass lens 5, and seeing through liquid crystal display screen 8 is refraction projection via two catoptrons 6,6 ' back.Because these liquid crystal display screen 8 areas are big than the LCD plate that the projection display uses, so better sharpness is arranged through enlarged image, adopt two L shaped catoptrons 6,6 ' that overall volume is dwindled, groove 11 is located at housing 1 left side or right side, also can be located at the top of housing 1.

As shown in Figure 3: the spill focusing mirror 2 of this housing 1, bulb 3 and collector lens 4 must be installed in the

slider case

12, and 12 of slider cases are contained on the end of housing 1, and in addition end is adorned one and fallen L shaped housing 13, adorns catoptron 6,6 ' respectively in its medial surface; Slider case 12 is outwards pulled out during use, and the L shaped housing 13 that falls is outwards raised, and liquid crystal display screen 8 is inserted in the groove 11 again, not the time spent, slider case 12 can be pushed in the housing 1, and fall L shaped housing 13 and can cover back housing 1, volume is greatly reduced, be convenient to carrying and deposit.

Claims

1, accurate liquid crystal data projector, it is characterized in that: it comprises a housing, inboard, housing below is provided with a spill focusing mirror, and establish a bulb in its focal position, and adorn a collector lens and glass lens in bulb the place ahead, establish a groove on the housing of glass lens the place ahead, housing holds inner face to be set as the L type with two catoptrons in addition, and a pancratic lens is established in the housing top; Adorn a liquid crystal display screen with connected computer of transparency function in the groove.
