Description

A kind of compact has the picture and text display of double-deck stereo video

Technical field

The present invention relates to a kind of picture and text display, particularly a kind of picture and text display with double-deck stereo video, utilize guiding device that light is imported display device inside, illuminate the picture and text sheet that places picture and text display inside, picture and text sheet image is derived via the total reflection effect of video servicing unit again, when watching, produce video with double-deck stereo sense.

Background technology

Picture and text display is the device that often uses in the life, the sign of trade name and price for example, the sign of showpiece title and brief introduction in the saloon, waiter's famous brand on the Counter service, the sign of commercial promotions propaganda etc.

Picture and text display; especially small-sized picture and text display; generally has the sweptback face of looking; watch conveniently to overlook; in order to see clearly Chu; particularly in the darker saloon of some ambient lightings; often need the special light of configuration, the light of these special configurations can cause interference to the saloon integrated environment; in addition; the inclination of conventional pictures display device is looked on the face, generally all has transparent support or protective seam, is incident upon transparent inclination and looks light on the face; can produce dazzling reflective and influence is watched; projector device in order not obstruct the view, is placed on position far away through regular meeting; therefore need more intense brightness, increased the consumption of electric energy.

For some sales promotion propagandas, it is mediocre that general picture and text display often seems, is difficult for producing attractive effect, thereby can't reaches sales promotion purpose preferably.

A kind ofly can produce novel sense, possess the interior lighting function, the display device of bright readability will help further to promote the application benefit of picture and text display.

Summary of the invention

Fundamental purpose of the present invention provides the picture and text display that a kind of compact has the double-deck stereo video, improves the novelty sense and the interest of watching.

Another object of the present invention is to utilize guiding device that extraneous light is imported display device inside, illuminates the displaying picture and text by inside, makes the observer only see the tattoo the face light of reflection through figure, does not rely on the external light of special configuration, avoids producing dazzling reflective.

A further object of the present invention provides a kind of light supply apparatus of providing for oneself, makes the brighter readability of graph-text content of displaying, and does not disturb peripheral environment, reaches the purpose of attractive attention.

For achieving the above object, a kind of compact of technical scheme of the present invention has the picture and text display of double-deck stereo video, with a light supply apparatus that comprises that the transparent prism guiding device of an isosceles right-angle triangle and covers on the guiding device string face is core, also comprise a video servicing unit and a base device, light supply apparatus covers the guiding device top in unbonded mode, launch light into guiding device, guiding device imports picture and text display inside with the light of injecting, illuminate the picture and text sheet that places the guiding device two personal share faces outside, it is the transparent prism of congruent figures with guiding device that the video servicing unit is one, base device is a plane device, first strand of face with a hypsokinesis miter angle and video servicing unit form angle-shaped groove always by face, the string face of video servicing unit is flat on the base device in unbonded mode, form a base air-gap, the square groove is accepted two personal share faces of guiding device in unbonded mode, first strand of face of guiding device and base device form one by the face air-gap by face, second strand of face of guiding device and first strand of face of video servicing unit form a video side air-gap, by inserting opaque erect image picture and text sheet in the face air-gap, insert transparent inverted image picture and text sheet in the video side air-gap.

Light supply apparatus is a passive type beam condensing unit, beam condensing unit covers on the string face of guiding device, and between the string face of guiding device air layer is arranged, the beam condensing unit bottom surface has not the parallel zigzag fully reflecting surface to scale, ambient light is imported guiding device, and the direction of zigzag fully reflecting surface is by face with the miter angle of light guide seats device.

Light supply apparatus is an active lighting device, and lighting device is covered on the string face of guiding device, has the optically focused reflecting surface, with the miter angle of active lighting device light guide seats device by face.

The light source of active lighting device is a light emitting diode, has light modulating device.

From technique scheme as can be seen the present invention have following beneficial effect:

The present invention makes and shows that content presents the stereoscopic sensation interest, and reaches the purpose of attractive notice.

When light supply apparatus is the passive type beam condensing unit, make the brightness of showing content, under the situation that does not have special illumination, also can make graph-text content bright outstanding greater than the brightness of peripheral environment.

When light supply apparatus is active lighting device, makes and show that content is brighter showy, and the observer only sees the tattoo the face light of reflection through figure, do not produce dazzling reflective.

Graph-text content is easy to change, and graph-text content has the stereoscopic sensation interest.

Particularly at some commercial locations or in the darker exhibition place of some ambient lightings, that the present invention possesses is bright noticeable, stereoscopic sensation is interesting, do not produce dazzling reflective, the performance of not disturbing peripheral environment, and existing same device can't be reached.
