Abstract

The utility model relates to a new type vehicle-mounted large screen back projection display equipment with filter glass, resolving the problems of displaying high-definition television image, character, digital and date effectively not only in stationary but also in moving. The utility model is characterized in that: a rolling advertising machine is arranged in the rear part of a housing, a light penetration lighting lamp box is arranged in the middle of the rolling belt of the advertising machine, a light barrier is arranged in the housing of the light penetration lighting lamp box, a reflected light plate is arranged on the light barrier obliquely, a projector vertical to the reflected light plate is arranged in the upper part of the housing, and a back projection screen is arranged in the anterior part of the housing next to one end of the projector. The utility model has the advantages of simple and novel structure, convenient installation and use, ability to display high-definition or standard-definition television image in moving and driving or in stationary, and ability to display still or continuous moving image, character, digital and data.

Description

The novel on-vehicle high-definition glass large screen back projection display apparatus

One, technical field

The utility model relates to a kind of movable type or fixed novel on-vehicle high-definition glass large screen back projection display apparatus.

Two, background technology

Existing display system has multiple: 1, high brightness luminescent pipe (LED) display system: the display system that a pixel is formed is done with the high brightness luminescent pipe by this system.Because spacing is big between the some pixel, the every square meter pixel of existing technology only can reach 40,000 pixels, and the shortcoming of this system is, can not show high-definition image and literal and data, and display image and literal and data are fineless and smooth to be not suitable for closely watching.And power consumption is big, and every square meter power consumption is 800 watts, and for one 20 square metres high brightness luminescent tube display screen, its pixel has 800,000 pixels at most, and power consumption reaches 16 kilowatts.So display condition is subjected to power limitations, can not be used for non-transformer area, mountain area, field, can not be used for moving demonstration.Its advantage is that brightness is higher, can use in the stronger place of ambient light;

2, liquid crystal display systems and plasma display system: owing to be subjected to the prior art condition restriction, the single screen of existing technology can only be accomplished 63 inches, can not accomplish large-scale seamless demonstration;

3, liquid crystal rear-projection display system: existing back casting large screen is to adopt the organic chemistry material to make foundation plate and make, because of limited by intensity and manufacture craft, existing screen is 200 inches to the maximum, being unable to undergo wind rain shines, can only be used for indoor, can not be used for vehicle-mountedly and outdoor, therefore, its innovation is imperative.

Three, utility model content

In order to overcome and remedy the deficiency of existing display system, the utility model provides a kind of tempering doubling glass to make the novel on-vehicle high-definition glass large screen back projection display apparatus of rear projection screen, not only effectively solve fixedly the time, also can solve and in moving, show the HDTV image, literal, numeral, problems such as data, the technical scheme of its solution is, include casing and rear-projection curtain, the rolling advertisement machine is housed in the casing rear portion, the illumination light transmission lamp box is housed in the middle of the rolling band of rolling advertisement machine, in the casing of illumination light transmission lamp box inner face, be equipped with every tabula rasa, the oblique reflector that is equipped with on the dividing plate light, in casing top, projector is housed perpendicular to reflector, there is the rear-projection curtain casing front portion by projector's one end, the utility model novel structure, simply, easy to install, can move travel in or show high definition fixedly the time, the Standard Definition Television image can show static and continuous mobile image and literal, numeral, data.

Because the utility model is removable, can fix, self is equipped with generator, UPS, solar electric power supply system, not limited by Power Supplies Condition, can be used for non-transformer area, mountain area, field.Because its rear projection screen is the tempering doubling glass rear projection screen that is made into new technology, its intensity height, not beneficial aging.Not only can be used for moving the demonstration of travelling, can also be used for indoor, outdoor fixed ultra-large type rear-projection and show.Flexibly, of many uses.Can be widely used in popularization on TV broadcast, competitive sports demonstration, advertising, theatrical performances, mobile movie projection team, alert with command system demonstration, military command system demonstration, the demonstration of Aero-Space command system.

Four, description of drawings

Fig. 1 is section of structure of the present utility model (dotted line is the light reaction situation among the figure).

Fig. 2 is a rear-projection curtain structure sectional view of the present utility model.

Five, embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Provide by Fig. 1, the utility model includes casing and rear-projection curtain, casing is equipped with rolling advertisement machine 3 in 1 rear portion, illumination light transmission lamp box 4 is housed in the middle of the rolling band of rolling advertisement machine, in the casing of illumination light transmission lamp box 4 inner faces, be equipped with every tabula rasa 5, the oblique reflector 6 that is equipped with is equipped with projector 8 perpendicular to reflector 6 on the dividing plate light 5 in casing top, leans on the casing front portion of projector's one end that rear-projection curtain 2 is arranged.

In order to guarantee result of use and sturdy and durable, tempered glass 7 is equipped with in the rolling band outside of rolling advertisement machine 3 in casing, rear-projection curtain 2 is the composite plane display body that is made of multilayer tempered glass layer 9, doubling layer 10, tempered glass layer 11, frosted layer 12 and optical lens optical coating layer 13 successively.

The utility model rear-projection curtain is to adopt tempered glass to do the basis, make through doubling, frosted, spraying optical lens optical coating, make rear projection screen with this version, and adopt existing projector technology, existing projector can reach more than 1,600 ten thousand pixels, and power consumption has only 1000-2000 watt, and brightness can reach more than 10000 lumens.Utilize the super large wide-angle lens, image is passed through the one or many reflective projection to rear projection screen, the sharpness height, visual strong, can form a high definition rear-projection display system with the computing machine of other configuration, HDTV player, magnetic tape type video machines, audio-frequency power amplifier, audio amplifier, generator, ups power etc.The hard curtain of the rear-projection that the invar doubling glass is made intensity height can be used for the open air and does large-scale demonstration, can be used for the vehicle-mounted demonstration of moving.Utilize van, with the both sides, compartment by loading onto the hard curtain of the rear-projection of making by the tempering doubling glass, form whole vehicle-mounted mobile high definition rear-projection display system, the middle demonstration of travelling can moved, its display resolution height, be subjected to that condition restriction is little, of many uses, power consumption is little, energy-conserving and environment-protective, cost of investment are low, be widely used on the outdoor and vehicle, economic and social benefit is huge.
