Abstract

The utility model discloses a color changeable flat display device, for providing a color changing, energy saving, long acting and ultra-thin flat display device. The utility model has a frame with die cavity, inner the frame is provided with a light spare plate, a light guide plate, a reflecting piece and a backboard. The front surface and the back surface of the light guide plate distribute diffusion points with different density, and the farther away from the light source the thicker of the diffusion points get. The side of the light guide plate is provided with a LED light source bar along the inner side of the frame, the light source bar chooses red, green and blue LED alternately assembling along a straight line, the LED connects into red, green and blue groups and separately connects with a time program controller, and after the power supply is turned on the red, green and blue groups of the LED separately produce a diversification of a bright and dark to mix the color, thus the varying color is shown on the outer light spare plate. A light transparent piece can be stick on the outer light spare plate, even a light-passing board can be mounted to make a color changeable frame and lamp house, and the device also can be made with double-face. The utility model can be used widely in the field of advertising decoration.

Description

The flat display apparatus of changeable colour

Technical field:

The utility model relates to a kind of flat display apparatus, relates in particular to a kind of flat display apparatus that utilizes super bright LED to make the changeable colour of light source.

Background technology:

Present big flat display apparatus generally all adopts fluorescent tube or incandescent lamp bulb to make light source, is not easy to the light modulation toning, therefore dull coloring not only, and also volume is big, quality heavy, high, cracky heat up.

Summary of the invention:

The utility model provides a kind of flat display apparatus that adopts super bright LED to make light source in order to overcome above-mentioned the deficiencies in the prior art, and it not only can change color, and has advantage energy-conservation, long-acting, ultra-thin, fabric width.

The utility model solves the problems of the technologies described above the technical scheme of being taked;

The utility model provides a kind of flat display apparatus of changeable colour, and it has a frame that has die cavity, and the inboard coated of frame has reflector layer, and frame can be circular, also can be polygonal.In the plane that frame is formed, even tabula rasa, light guide plate, reflecting piece, backboard are installed successively after by forward direction.Side in light guide plate, along on the periphery of scuncheon, also can on one group of opposite side of polygon frame or a limit, the led light source bar be installed, described led light source bar selects for use the LED of three kinds of colors of red, green, blue alternately to install along straight line, LED connects into three groups of red, green, blues and is connected to respectively in the time schedule controller on separately the driving circuit, thereby colour mixture is carried out in the variation that three groups of LED of red, green, blue alternately produce shading value respectively after the energized.The two sides, front and back of described light guide plate is distributed with the diffusion point that density does not wait, and is close more apart from the position diffusion point that light source is far away more.

The utility model can be the flat display apparatus of single face changeable colour, also can the flat display apparatus of sparing tabula rasa and becoming variable double sided look all only be installed on the two sides, front and back of light guide plate.Also can outside described even tabula rasa, mount printing opacity lamp sheet, can also outside described printing opacity lamp sheet, install light-passing board and make various changeable colour picture frame, lamp box.Compared with prior art the utlity model has following advantage;

1, because of selecting for use LED as light source, its luminous quantity can be regulated easily, three groups of LED of red, green, blue are by the control of time schedule controller in the utility model, and colour mixture is carried out in the variation that shading value alternately takes place respectively for three groups of LED, therefore can produce colourful change color.

2, select for use LED as light source because of the utility model, so this device have that power consumption is few, temperature rise is little, shock resistance, long advantage of life-span.

3, the utility model is selected the medium of light guide plate as light for use, the effect that utilizes the light guide plate total reflection is with the light far-end that leads, the acting in conjunction of the diffusion point that on the light guide plate plane, distributes, even tabula rasa etc., make this device not only can on bigger plane, demonstrate uniform color, and can do very thinly

Embodiment:

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

With reference to Fig. 1, preferred embodiment of the present utility model has a rectangular shaped rim 1 that has die cavity, and the inboard coated of frame 1 has reflector layer.In the plane that frame 1 is formed, even tabula rasa 2, light guide plate 3, reflecting piece 4, backboard 5 are installed successively after by forward direction.The two sides, front and back of described light guide plate 3 is distributed with the diffusion point that density does not wait, and is close more apart from the position diffusion point that light source is far away more.The installation of the utility model electrical appliance part is with reference to shown in Figure 5, at the side of light guide plate 3, along on one group of opposite side of the inboard of frame 1 led light source bar 6 being installed, at frame 1 inboard one jiao time schedule controller 7 is installed.Described led light source bar 6 is alternately installed along straight line by red, green, blue LED, and their are formed three groups of red, green, blues and are connected in the time schedule controller 7 on separately the driver.Colour mixture is carried out in the variation that three groups of LED of red, green, blue alternately produce shading value after the energized under the control of time schedule controller 7, and variable color light is through the reflection of transmission, diffusion and the reflecting piece 4 of light guide plate 3, in the variation of the surperficial display color of even tabula rasa 2.

With reference to Fig. 2, be another embodiment of the present utility model, specific practice is on the two sides, front and back of light guide plate 3 even tabula rasa 2 only to be installed all, the utility model just becomes the flat display apparatus of variable double sided look.

With reference to Fig. 3, be another embodiment of the present utility model, specific practice is in the outside of even tabula rasa 2 printing opacity lamp sheet 8 to be installed, the utility model just becomes picture frame, the lamp box of variable double sided look.Can certainly make single face.

With reference to Fig. 4, be another embodiment of the present utility model, specific practice is in the outside of printing opacity lamp sheet 8 light-passing board 9 to be installed, the utility model just becomes picture frame, the lamp box of the single face changeable colour with light-passing board protective seam.Can certainly make two-sided.

With reference to Fig. 6, it is the electric functional-block diagram of time schedule controller 7 of the present utility model, deliver to the sequential coding circuit after the step-down of civil power process, rectification, the voltage stabilizing, the control signal of sequential coding circuit removes to control each driving circuit through output terminal, make each driving circuit export the electric current of big or small alternate respectively, the electric current that changes makes each led light source group of red, green, blue produce the variation of bright-dark degree respectively, thereby reaches the purpose of colour mixture variable color.
