Description

Electro-optical display device

Invention field

The present invention relates to electro-optical display device, it can show various forms of figures and letter with the light compositing color of being undertaken by the light reflection, relates in particular to the electro-optical display device that can be used for billboard or decorate picture frame.

Background technology

Can very simply lighting devices that are used for billboard more.

That is, required letter shapes shows or illuminate billboard from the inside or the outside of billboard as long as neon tube bent to.

Yet, if billboard utilization neon tube, because it is made by crooked neon tube, therefore can not represent little letter or meticulous figure, if and size is bigger, then can not form integral body to single letter or figure, thereby it can only produce very rough advertising results, on the contrary, it exists that energy consumption is big, the gas of neon tube device utilization also brings environmental problem, volume is big, manufacturing time is long and must the expensive shortcoming such as high voltage transformer of use price.

In addition, it is too simple that the fluorescent light by billboard inside or outer setting illuminates the surface of billboard, thereby be difficult to obtain required advertising results and it visually gives the in disorder sensation of people.

In order to solve these shortcomings, recently promoted a kind of billboard, be used for obtaining various advertising results by the luminous of control light emitting diode by arranging light emitting diode, but because the arrangement of a large amount of light emitting diodes and wiring need many times and very expensive, if and when a part of shortage is not easy to repair, thereby stay ugly figure, this is a truth of having introduced the public pollution of advertisement.

In addition, also use the billboard (its shades of colour can change fine) of utilization optical fiber, but not only need to arrange a large amount of optical fiber, and need a lot of manufacturing times and very big expense, and because it comes display graphics by point, so be difficult to make optical fiber arrangements figure continuous, thereby its shortcoming is to be used for bigger billboard.

In addition, a kind of billboard that uses LCD panel recently also occurred, but because producing cost is too high and very strict to the technical limitation of size, needed for a long time so actual conditions are its popularizations.

Summary of the invention

Therefore, consider the problems referred to above, the purpose of this invention is to provide a kind of electro-optical display device, there is not the complicacy of the obstacle figure and the letter of size in it, and changeable color is changed.

Another object of the present invention provides a kind of electro-optical display device, and it very simply reaches compactness and color is clear in the inside and outside configuration aspects of billboard, and is very attractive in appearance.

To achieve these goals, the present invention includes:

The laminated member that transparent plastic sheet by stacked a plurality of plate shapes forms;

By carve out the photo-emission part branch that letter or figure form at the rear portion of transparent plastic sheet;

The coating that the polymeric material that refractive index by coating the refractive index ratio plastic plate on the surface of plastic plate is big forms;

The coloured part that optionally adds paint (paint) has only the luminous energy of special color to pass through along all directions of the every plastic plate side that forms laminated member;

By laying the carriage that laminated member fixes;

A plurality of partitions that are integrally formed on the carriage, they are inserted between carriage and the laminated member, thereby are separated out each independent cavity;

At least one illuminating lamp that in each chamber of separating by partition, is provided with, bulb comprises convergent lens in the face of the part of laminated member side; And

Illumination control apparatus is used for controlling the brightness of the illuminating lamp that each chamber is provided with and lights order.

Best mode for carrying out the invention

Below, will be described in greater detail with reference to the attached drawings preferred embodiment of the present invention.

Fig. 1 illustrates sectional view of the present invention, and is stacked together the transparent plastic sheet 1 that has by the Bao Erkuan of a plurality of plastic plates of being done by acrylic resin board (cheap and as easy as rolling off a log acquisition) etc., thereby formed billboard or decorated the laminated member of picture frame effect.

(that is, the bottom surface) gone up with opposite shape and carved out required designs for advertisement such as letter or figure overleaf, divides 3 (making the light reflection when the interface of being carved receives the light time) thereby form photo-emission part.

Form coating 4, wherein at least one side of plastic plate 1, add polymeric material rather than plastic plates such as silicones thinly.Because coating 4 is polymeric materials, so the refractive index of light is very high, and because it is very high to the reflecting properties that reflected with the light greater than predetermined angular incident, so when the time from following illuminating lamp 5 radiant lights, its effect becomes separation layer, be used for isolating to contiguous plastic plate leak light, thereby optical convergence divides 3 to photo-emission part, to obtain color more clearly.

Label 6 is by laying the carriage that laminated member 2 is used for fixing, integrally form a plurality of partitions 7, and the contacts side surfaces of the end of partition 7 and laminated member 2, thereby comprised the independent cavity of separating by partition 78.

One or more illuminating lamps 5 are arranged in each chamber 8.Illuminating lamp 5 passes through the internal radiation light of the lateral parts of plastic plate 1 to plate, bulb forms convex lens 9 in the part of the lateral parts of facing plastic plate 1, and the remainder of bulb adds lighttight materials such as mercury, thereby prevent that light from dispersing along all directions of illuminating lamp 5 sides, and light is assembled by convex lens 9, has therefore increased the ability that light is concentrated to forward direction.

In the face of the plastic plate 1 of each chamber 8 of forming by a plurality of partitions 7 side periphery colored red (R), green (G), yellow (Y), blueness multiple colors such as (B) in a kind of paint of printing opacity of color, or form the coloured part 10 that pastes mutually with isolation autochromatic plate, the color of passing through of the definite light to plastic plate 1 internal radiation of coloured part 10 with this color.

Fig. 2 illustrates the sectional view of the plastic plate 1 that is carved with design for advertisement, it illustrates plastic plate 1 and is carved chevron, curved, smooth sea shape, thereby form reflecting part 3 because the reflection of light degree with the engraving shape difference, so make atmosphere some difference slightly according to carving shape, the general chevron (∧ shape) of using more, if and carve chevron (∧ shape), then the inclination angle at interface is preferably in about 15-45 degree, at this moment, because the inclined-plane that carves is a translucent, the institute so that light reflect to forward direction.

Fig. 3 illustrates the figure that is subjected to from the zone of the influence of light of illuminating lamp radiation because each illuminating lamp is only luminous to forward direction, so have only the part of plastic plate 1 to be illuminated, but because a plurality of lamps arrange round all directions of plate, so do not produce the dead angle area of light.

Fig. 4 illustrate when when 1 piece ground of each plastic plate being separated the letter of carving out negative shape or figure (for example in the present invention, the sea-gull shape that is carved with English letters COKE and circles in the air), be carved with the skeleton view of laminated member 2 decomposition of letter and figure at sea.

The quantity of the plastic plate 1 that use this moment according to letter or figure preferably from two (2) to six (6), in the present invention,, use four plastic plates comparatively convenient because COKE comprises four letters.

At first, go up engraving C at first block of plate 11 (top layer plastic plate), on second block of plate 12, carve O corresponding to its character position, on the 3rd block of plate 13 and the 4th block of plate 14, carve K and E respectively, figure (promptly, ring, sea-gull, wave) divide on every block of plate and and carve with identical method, after this when four flaggies were stacked, COKE and figure can be seen in the front that sees through laminated member.

Fig. 5 illustrates the front elevation of one embodiment of the present of invention, the length of plastic plate with widely be divided into four equal parts, and be isolated into four chambers respectively, lateral parts at every plastic plate facing each chamber 8 is coated the paint of special color or is being sticked coloured plate, thereby form coloured part 10, for example, viridescent plate (G) and be attached to first lamp A place on the plate 11, red plate (R) and be attached to second lamp B place on the plate 12, yellow plate (Y) and be attached to the 3rd lamp C place on the plate 13, blue plate (B) and be attached to the 4th lamp D place on the plate 14, or be coated with so that the paint of the light transmission of this color.

Each illuminating lamp 5 is linked and is used to control the illumination controller 15 of lighting order, lighting the brightness of time and light, thereby operate according to the state that is input to illumination controller, as light the ornament lamp of Christmas tree, can produce different illuminating states according to program.

If light A lamps all in each chamber, then, bump against photo-emission part then and divide 1 (interface portion of letter C), thereby can see green letter C by forward direction by the green portion (G) of first block of plate 11 of light transmission of each A lamp radiation by illumination controller.

The reason that produces this phenomenon is because the interface portion of carving out from plastic plate stops that the straight line of light moves, make light transmission green portion (G) from the radiation of A lamp, bump against the photo-emission part branch that forms by letter C then, thereby changed direction of light and advanced, thereby can see and the identical letter of viridescent part (G) color to the forward direction of laminated member.

On the other hand, when lighting all remaining B, C and D lamp simultaneously, can see green letter C, red alphabetical O, yellow alphabetical K, and blue letter e, each letter is presented by different colors respectively, if and photo-emission part divides 3 light that receive multiple color simultaneously, then letter becomes the color with synthetic light.

That is,,, and whether light illuminating lamp 5, can become shades of colour to letter and figure continuously according to the time according to 10 pairs of painted colors of plastic plate 1 interface portion of coloured part corresponding to each chamber 8 because light can present all colors by synthetic.

For helping to understand the present invention, the foregoing description is an example with single product of planting color, if but resemble and construct Fig. 6, then can produce unlimited multiple color.

In the embodiment of Fig. 6, if the lateral parts of all plastic plates 1 is worn into different colors by the partitioned portion branch, and each chamber is had more than an illuminating lamp, convergent lens part (front portion of illuminating lamp) is also divided under the situation of the paint that wears different colours then, can produce the different color as the color TV piece image.

Promptly, bump against the photo-emission part branch of letter or figure from the light of the color that has nothing in common with each other of all direction radiation of plastic plate, changing direction then advances to the forward direction of plastic plate, produce the letter or the figure of synthetic color simultaneously, at this moment, if in a chamber, provide a plurality of illuminating lamps, and plastic plate and illuminating lamp all on the color coloured silk that has nothing in common with each other, then basis is positioned at the combination of lighting of lighting combination and all lamps of a plurality of illuminating lamps of a chamber, can present the different color that to describe really, only by colored state and lighting control and can make all these become possibility to illuminating lamp.

Here, do not need all parts painted, and if special part not go up any color, then because radiation white light in fact, so by synthetic other coloured smooth scalable brightness and atmosphere.

The work of the present invention and the effect that so constitute below will be described.

To a plurality of plastic plates of preparing, make being separated into several parts and carving on different plates also stacked respectively of letter and figure.When seeing so stacked plate from the front, what see is complete letter and figure.Because the side of the illuminating lamp that provides in each chamber has added lighttight material, thereby strengthened the convergence and the rectilinear propagation characteristic of light, can reduce required power consumption, and can increase the sharpness of design for advertisement.

Below will enumerate effect of the present invention in more detail.

The first because this equipment of the present invention can be only the control of lighting by illuminating lamp freely produce different colors by the synthetic ten minutes of light, so significantly advertising results are splendid,

The second, because the simple layer stack structure of transparent plastic sheet, do not introduce tangible public pollution the common billboard so do not resemble.

The 3rd, because can on plastic plate, present extremely meticulous figure with the computing machine engraving machine, thus can make various advertisement,

The 4th, because only appear the design for advertisement of letter and figure, so electric work consumption is seldom,

The 5th, because occupation space is little and do not need to show the part of letter or figure fully, thus in light weight and manufacturing cost is very low,

The 6th, because there is not flimsy part, so service time is long and easy M R.

Should notice that the present invention is not only limited to the foregoing description, from claim described below, find the different only foreseeable equivalent that changes of the present invention, also can carry out different utilizations it.
