Abstract
The utility model relates to a flexible surface mount device (SMD) light emitting diode (LED) display screen, which comprises a flexible circuit board and a plurality of SMD LEDs welded on the circuit board and is characterized in that the flexible circuit board is made of flexible insulation substrates, and the distance between any two adjacent SMD LEDs is not greater than 2.0mm, wherein each SMD LED comprises a welding disc, a red LED chip, a green LED chip and a blue LED chip, and the red LED chip, the green LED chip and the blue LED chip are welded on the welding disc in a shape of a equilateral triangle and are in homopolar connection through gold wires. The flexible SMD LED display screen has the advantages that the display screen can be arranged on a curved surface building, the image resolution is improved, and a better image display effect is reached.
Description
Technical field:
The utility model relates to the LED display technique, is specifically related to a kind of flexible SMD LED display.
Background technology:
The LED technology is more and more ripe, has been widely used in industry and various fields in life.A kind of LED that SMD LED grew up especially in recent years, SMD LED is exactly the meaning of surface patch light emitting diode, is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity.Wherein SMD LED more is used for display screen and field of light fittings, has advantages such as volume is little, scattering angle is big, uniformity of luminance is good, reliability is high, speed of production is fast, purposes is wide, and its glow color can be that white light is at interior shades of colour.
LED display all adopts the hard wiring board to be made at present, the inflexibility of hard wiring board, can not be implemented on some curved-surface building thing and use, and also there is the restriction of manufacturing process in the LED display that this hard wiring board is made, makes that its pixel minor increment is bigger, and foot has 4mm, because the unit area pixel is many more, the resolution of image is just high more, and therefore, this hard wiring board LED display image does not reach optimum efficiency.
The utility model content:
The purpose of this utility model is exactly the deficiency at prior art, and a kind of flexible SMD LED display is provided, can use at curved surface and non-curved-surface building surface, and the spacing between two neighbor pixels is not more than 2.0mm, increase the resolution of image, reach best display effect.
Technology solution of the present utility model is as follows:
A kind of flexible SMD LED display, comprise flexible circuit board and welding a plurality of SMD LED in the circuit board, the flexible circuit board that described flexible circuit board is made for the flexible insulation base material, spacing between described any two adjacent SMD LED is not more than 2.0mm, wherein said SMD LED comprises pad and is welded on red LED chips on the pad, green LED chip and blue led chip, described red LED chips, green LED chip and blue led chip are equilateral triangle and are welded on the pad described red LED chips, link to each other by the gold thread homopolarity between green LED chip and the blue led chip three.
Also be provided with the electron scanning driving circuit on the described flexible circuit board, electronic drive circuit control SMD LED sends the light with drive signal respective color and brightness.
Beneficial effect: the utility model adopts flexible circuit board to make the SMD LED display, can arrange arbitrarily according to space layout, can be so that display screen is installed on the curved-surface building thing.Simultaneously, the distance between any two adjacent SMD LED shortens, and has improved the resolution of image, reaches the better pictures display effect.
