Abstract

The utility model relates to a supplemental application to the application of No. 85202605 utility model (the name is: time-space division rotary type electronic display screen) in Taiwan, China. A rotary body is provided with a plurality of rows/lines of lighting units, and the light emission of the lighting units is controlled at the appropriate time. When the rotary body rotates, the rotary surface of the rotary body can generate a specified pattern using the persistency phenomenon of human vision to image. Moreover, each lighting unit is respectively covered a layer of polarizers, and the polarizers which are positioned outside of the adjacent lighting units have mutually perpendicular polarization directions. Thereby, the images generated by the adjacent lighting units is truly divided. When a user puts on a pair of polarized glasses to view and admire, a left image and a right image which are generated by the adjacent lighting units can be separated to send to the left eye and the right eye of the user respectively, and thus a stereo image can be generated on the sight line of the user.

Technical field

The utility model be No. the 85202605th, TaiWan, China utility model (name is called: space-time is cut apart the rotary electronic display screen " utility model application append application; refer to that be vertical polaroid a kind of setting up separately with the polarization direction outside each adjacent luminescence unit mutually on rotary body; make image that adjacent luminescence unit produces be able to certain separation, and when the user puts on polarising glass, viewed and admired the space-time divided display curtain of stereopsis.

Background technology

The applicant had before obtained No. the 12003rd, TaiWan, China utility model patent " space-time is cut apart the rotary electronic display screen ", and it mainly is to set up number row or number row luminescence unit on a rotary body separately, and in due course control it is luminous.When rotary body rotates with suitable speed, the surface of revolution of this rotary body will utilize the image persistance phenomenon on the human vision and produce specific pattern.By this, need only utilize the number row of minority or number row luminescence unit can produce the display frame that can constitute, thereby can reduce the consumption of luminescence unit in a large number, and reduce manufacturing cost, increase economic efficiency by tens times of luminescence unit beginnings.

Apply for that now the people more becomes vividly for making its display frame, be to do further self-criticism with reaching effect, and deeply study intensively its possible improvement space at the structure of aforementioned patent case.And find that after self-criticism research though aforementioned display screen utilizes the phenomenon that persists on the special structure design fits human vision, and can produce specific pattern on the rotary body surface, this pattern only terminates in plane pattern, and is comparatively plain with regard to visual effect.And, in fact can see through particular processing with present optical technology, common people are seen on the display screen on plane be an instantiation as three-dimensional film by three-dimensional pattern.

Three-dimensional film in the past, be to utilize the polariscope that on two projector heads, adds left and right sides different polarization direction, about two mutually perpendicular images in polarization direction stamp screen, reflect back into by screen again and wear the spectators that are the vertical polarization glasses mutually, and spectators can see through polarising glass and see three-dimensional image.Yet owing to can't hundred-percently keep the polarization of original incident light after the screen reflection, thereby the shortcoming that often has left and right sides image to separate fully.A kind of optical gate switch (optical valve) is arranged again at present, can be for watching left and right sides picture synchronously and produce preferable stereoeffect, but because the viewing-mirror price height that constitutes of optical gate switch synchronously, and it is inconvenient to make us sensation on using.

Therefore, how to use the known technology principle to make previous rotary display screen be produced space pattern, the unlikely left and right sides image that occurs separates or the cost problem.

The utility model content

For this reason, the utility model fundamental purpose improves at female case and can produce the rotary display screen of space pattern providing a kind of, it makes the luminescence unit on the rotary body directly produce the image polarized light, and directly enter spectators' sight line, make the polarization image produce hundred-percent left and right sides separating effect.

For reaching technological means that aforementioned purpose takes is that to make aforementioned rotary electronic display screen be to establish on a rotary body with number row or number row luminescence unit, and in due course control it is luminous, when rotary body rotates, utilize the persist phenomenon of human vision, and on the surface of revolution of rotary body, produce specific pattern for image; It is characterized in that:

Each luminescence unit is covered with one deck polaroid (polarizer) outward respectively, and adjacent luminescence unit system sets up the orthogonal polaroid in polarization direction separately, and the image that adjacent luminescence unit is produced separates really;

When spectators put on polarising glass and watch rotary body, can effectively separate the left and right picture that adjacent luminescence unit produces on the rotary body, and enter its images of left and right eyes sight line respectively, and on its sight line, produce stereoscopic picture plane.

Aforesaid luminescence unit is to be provided with a plurality of light emitting diodes with arranged on a circuit board, and the light emitting diode of each row also is respectively different colors, under its rotary body rotation status, lights with reasonable time, brightness, can constitute colored pattern.

For ease of further aforementioned purpose of understanding and architectural feature of the present utility model, attached now with accompanying drawing detailed description as back:

Embodiment

Relevant structure of the present utility model at first sees also shown in Figure 1ly, mainly is luminescence unit (11)～(18) that are provided with many groups on a rotary body (10), and wherein, the shape of this rotary body (10) can be cylindric, spherical or discoid person.Each luminescence unit (11)～(18) are with equiangularly arranged again.Each luminescence unit (11)～(18) can be made up of the luminophor of several different colours again, generally can form by three kinds of luminophors of red, green, blue (R.G.B), the luminophor of various different colours (R.G.B) when rotated will be overlapping on same track while scan, thereby through luminous angle and the time width thereof of each luminophor of control, i.e. its brightness of may command; Particularly, be to utilize pulse width modulation method (PWM) to reach the purpose of control brightness, thereby can form required image after the luminophor of the variant color process PWM control colour mixture.

Concrete structure about luminescence unit (11)～(18) sees also shown in Figure 2 again, with a luminescence unit (11) wherein is example, mainly be on a circuit board (110), to be arranged with three row light emitting diode (111)～(113), each row light emitting diode (111)～(1113) is made of the light emitting diode of different colours respectively, promptly as discussed previously, it is red, green and blue that the color of each row light emitting diode (111)～(113) is respectively.

And be to reach the purpose that picture that adjacent luminescence unit produces separates really, the outer transparent polaroid (114) that is arranged with of this luminescence unit (11), this polaroid (114) has specific polarization direction, in the present embodiment, polaroid (114) polarization direction of this luminescence unit of definition (11) is in the horizontal direction earlier.

See also shown in Figure 3 again, be another luminescence unit (12) adjacent with aforementioned luminescence unit (11), its essential structure is still identical with luminescence unit (11), mainly be on a circuit board (120), to be provided with three rows to be respectively light emitting diode (121)～(123) of red, green, blue look, and be provided with the polaroid (124) of a particular polarization in the outside.

With last adjacent luminescence unit (11) unique different be in: the polarization direction that this luminescence unit (12) is gone up set polaroid (124) is orthogonal with polaroid (114) polarization direction of adjacent luminescence unit (11), and meaning i.e. polaroid (124) polarization direction of this luminescence unit (12) is in vertical direction.

And promptly set up separately with the mutually perpendicular polaroid in polarization direction in alternate mode luminescence unit (11)～(18) of respectively organizing on the rotary body (10), for example, luminescence unit (11) (13) (15) (17) as odd number is when being covered with the polaroid of horizontal polarization direction, and the luminescence unit of even number (12) (14) (16) (18) promptly is covered with the polaroid of vertical polarization.

When the polaroid on the luminescence unit (11) (13) (15) (17) is horizontal polarization direction, all all will be polarized by its corresponding horizontal polarization sheet at this any light that light emitting diode sent of organizing on the luminescence unit (11) (13) (15) (17), and meaning promptly is partial to horizontal direction; And other luminescence units (12) (14) (16) (18) adjacent with aforementioned luminescence unit (11) (13) (15) (17), its polaroid then is a vertical polarization, so all will be polarized by its corresponding vertical polarization sheet at this any light that light emitting diode sent of organizing on the luminescence unit (12) (14) (16) (18), meaning promptly is partial to vertical direction.

Can produce the image of two different polarizationization by this, image as formation horizontal direction polarization such as luminescence units (11) (13) (15) (17), adjacent luminescence unit (12) (14) (16) (18) etc. then forms the image of vertical direction polarization, these two images are simultaneous, and can independently play different images.Therefore what hypothesis was play is two pictures that left and right parallactic angle is suitable, and then spectators have worn the corresponding polariscope in the left and right sides, produces stereoeffect when left and right picture is separable into left and right image during by polariscope.Mainly be because luminescence unit (11)～(18) are by spectators' direct viewing, thus almost can absolutely separate behind the mutually perpendicular polariscope of left and right image process, and reach very desirable stereoeffect.

From the above, the utility model mainly is to set up separately on the adjacent luminescence unit of rotary body with different polarization direction and orthogonal polaroid, make all light that each light emitting diode produces on each luminescence unit all be polarized through polaroid earlier, after spectators put on the corresponding polariscope in the left and right sides, but during the image that produces by luminescence unit on the direct viewing rotary body, the left side that adjacent two luminescence units are produced, the certain separation of right image, to produce splendid stereoeffect, and the generation of this kind stereopsis, and need not use expensive optical gate switch, so be a kind of cheap and stereopsis rotary display screen curtain that effect is distinguished, and also have a remarkable efficacy compared to female case and promote.
