Abstract
The invention discloses an indoor soft full-color LED display screen, comprising a circuit board and a plurality of SMD light-emitting diodes (LED) which are welded on the circuit board; wherein the circuit board is a soft circuit board made of soft insulating material. The distance between every two adjacent SMD light-emitting diodes is not more than 2.5mm. The LED display screen welds the SMD light-emitting diodes (LED) in a triangular arrangement on the soft circuit board and controls the color and the brightness of the SMD light-emitting diodes though an electronic scanning drive circuit, thus not only improving the resolution of the indoor soft full-color LED display screen, but also enabling the indoor soft full-color LED display screen to be installed on a curved wall.
Description
Technical field:
The present invention relates to the LED display technique, particularly be a kind of indoor flexible full-colored LED display screen.
Background technology:
Along with the development of society and the raising of people's material and cultural life, LED display has progressed into individual domestic consumer.And the indoor display screen of LED all adopts the hard wiring board to be made at present, inflexibility, can not be implemented on some curved-surface building thing and use, and the indoor display screen of LED that this hard wiring board is made is because the restriction of its manufacturing process, make the minimum spacing of its pixel can only be 4MM, because dot spacing is more little, the pixel of unit area is just many more, the resolution of image is high more, the image reality resolution of the therefore existing indoor display screen of LED does not reach best effect, thereby can't realize that real TV shows the screen effect.
Summary of the invention:
In order to solve the not high problem of resolution that the existing indoor display screen of LED can't be applied to curved-surface building thing and image, the object of the present invention is to provide a kind of indoor flexible full-colored LED display screen, the present invention not only can be installed on the curved-surface building thing, and the spacing between its any two neighbor pixels is not more than 2.5MM, thereby increase the resolution of display image, reach TV and show the screen effect.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of indoor flexible full-colored LED display screen comprises wiring board and welding a plurality of SMD LED in the circuit board, the flexible circuit board that wherein said wiring board is made for the flexible insulation base material, and the spacing between described any two adjacent SMD LED is not more than 2.5MM.
Wherein said SMD LED comprises pad and is welded on red LED chips, blue led chip and green LED chip on the pad, described red LED chips, blue led chip and green LED chip are triangular in shape to be welded on the pad, links to each other by the gold thread homopolarity between described red LED chips, blue led chip and the green LED chip three.
Wherein said SMD LED forms by the transparent epoxy resin encapsulation.
Also be provided with the electron scanning driving circuit on the wherein said wiring board, described electronic drive circuit is used to control SMD LED and sends light with drive signal respective color and brightness.
The flexible circuit board (FPC) that the present invention utilizes the flexible insulation base material to make replaces existing hard system wiring board, and the SMD LED that forms that red LED chips, blue led chip and green LED chip are evenly arranged by triangle is as the base pixel point of display screen, thereby produced following beneficial effect:
1, flexible circuit board can require to arrange arbitrarily according to space layout, and mobile arbitrarily and flexible at three dimensions, thereby reaches integrated that the components and parts assembling is connected with lead, and display screen is installed on the indoor curved-surface building thing becomes possibility.
2, utilize flexible circuit board can dwindle the volume of electronic product greatly, spacing is dwindled, thereby improve the resolution of display image, reach better display effect.
Description of drawings:
Fig. 1 is a Facad structure synoptic diagram of the present invention.
Fig. 2 is a SMD LED structural representation of the present invention.
Identifier declaration among the figure: flexible circuit board 1, SMD LED 2, pad 3, transparent epoxy resin 4, green LED chip 5, blue led chip 6, red LED chips 7.
Embodiment:
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
As Fig. 1～shown in Figure 2, the present invention is a kind of indoor flexible full-colored LED display screen, comprise wiring board and welding a plurality of SMD LED 2 in the circuit board, wherein said wiring board is the flexible circuit board 1 that adopts the flexible insulation base material to make, and evenly being welded with a plurality of SMD LED2 on this flexible circuit board 1, the spacing between described any two adjacent SMD LED 2 is not more than 2.5MM.
Each SMD LED 2 all can be considered an independently pixel among the present invention, its concrete structure sees also shown in Figure 2, here SMD LED 2 is formed by transparent epoxy resin 4 encapsulation by pad 3 and led chip, wherein led chip comprises red LED chips 7, blue led chip 6 and green LED chip 5, red LED chips 7 described here, blue led chip 6 and green LED chip 5 are triangularly arranged and are welded on the pad 3, and the positive pole back that links together welds together with flexible circuit board 1 between three led chips, negative pole is welded on respectively on the flexible circuit board 1, be formed by connecting according to certain circuit relationships between a plurality of like this SMD LED on the flexible circuit board 1, the positive pole of each SMD LED can link together.
On flexible circuit board 1, also be provided with an electron scanning driving circuit in addition, the video input signals of outside can be changed into the corresponding driving signal by this sweep circuit, and send and corresponding color of vision signal and brightness by this electron scanning driving circuit control SMD LED.
Because the flexible circuit board 1 that the present invention adopts is four layers of flexible circuit board, its Copper Foil with perfect heat-dissipating is a base material, and structure with the good double-side hollowed-out of ventilation effect, therefore this flexible circuit board 1 has good performance of heat dissipation, therefore the spacing between a plurality of SMD LED that weld on this flexible circuit board can be accomplished very little, spacing between adjacent two the SMD LED of the present invention can accomplish to be not more than 2.5MM, so just can on the flexible circuit board on the equal area, weld more SMDLED, the resolution that image is shown improves greatly, thereby can reach the resolution of TV, make the present invention can reach the effect that TV shows.
The present invention is welded on the flexible circuit board by the SMD LED that forms that triangle is arranged, and control SMD LED by the electron scanning driving circuit and send corresponding color and brightness, thereby not only improved the resolution of indoor flexible full-colored LED display screen, and on some curved surface things, also can realize installing.
More than a kind of indoor flexible full-colored LED display screen of the present invention is described in detail, used specific case in this instructions principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand core concept of the present invention; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
