Abstract
The utility model relates to an LED (light-emitting diode) display screen, which belongs to the technical field of LEDs. The structure of the LED double-sided display screen comprises five parts, namely an LED lamp bead 1, a PCB (printed circuit board) lamp panel 2, a metal profile 3, a pressure-riveting nut column 4 and a box body framework 5, wherein positioning pin holes 7 are manufactured at two ends of the box body framework 5, and two or more box body frameworks 5 can be tightly combined for forming the display screen in larger area by using positioning pins 6. The LED display screen with the structure can realize double-sided display and increase the display area; furthermore, as the positioning pin holes and the positioning pins are manufactured at the top end of the box body framework, the LED display screen in the large area can be manufactured by only connecting two or more display screens through the positioning pins, and the manufacturing, the maintenance and the replacement of the LED display screen become very simple and convenient.
Description
Technical field
This patent relates to a kind of LED display, belongs to the LED technical field.
Background technology
LED display (LED display) is electronic display again or the word screen that wafts.Be made up of the LED dot matrix, the light on and off by LED lamp pearl come display text, picture, animation, video, and content can be changed at any time, and the each several part assembly all is the display device of modular construction.Usually form by display module, control system and power-supply system.The dot matrix that display module is made up of the LED lamp constitutes, and is responsible for luminous demonstration; Control system can allow contents such as screen displaying character, picture, video by the light on and off of control respective regions; Power-supply system is responsible for transferring input voltage and input current to display screen required voltage electric current.
LED display is the novel demonstration product that develops rapidly in the whole world in the later stage eighties in last century, shoots up to be the main product of flat pannel display.Why LED display is subjected to extensively paying attention to and is developed rapidly, is that the advantage that had with itself is inseparable.These advantages are summarized: the brightness height, operating voltage is low, power consumption is little, miniaturization, the life-span is long, shock-resistant and stable performance.The development prospect of LED is very wide, and at present just towards high brightness more, more high weather resistance, higher luminous density, higher uniformity of luminance, reliability, panchromaticization direction develop.
But conventional LED display hangs or posts up support or building wall surface, can only show by single face, and the conventional LED display of outdoor mostly is an one-piece construction, because area is bigger, and the making of display screen, maintenance or change all very trouble.
Summary of the invention
For solving the problems referred to above that conventional LED display exists, the present invention proposes a kind of LED two-sided display screen.
A kind of LED two-sided display screen, its structure comprise LED lamp pearl (1), PCB lamp plate (2), shape (3), Self-Clinching Standoffs (4) and box frame (5) five parts composition, and wherein, LED lamp pearl (1) is fixed on the PCB lamp plate (2); Shape (3) tow sides are manufactured with slot respectively, can place the PCB lamp plate (2) that has LED lamp pearl (1) in the slot; PCB lamp plate (2) in shape (3) and the slot constitutes single lamp bar jointly, adopts Self-Clinching Standoffs (4) that the lamp bar is fixed on the box frame (5), constitutes two-sided display screen.
Shape (3) can adopt aluminium alloy extrusions, has good heat dissipation, light weight, and intensity advantages of higher.
In addition, box frame (5) two ends are manufactured with dowel hole (7), use register pin (6) two or more box frames (5) can be combined closely more large-area display screen.
LED display with this structure, can realize double-sided display, increased display area, and because the box frame top is manufactured with dowel hole and register pin, only two or more display screens need be connected by register pin, can make the large area LED display screen, make making, maintenance and the replacing of LED display all very easy.

Specific embodiment
A kind of LED two-sided display screen, its structure comprise LED lamp pearl (1), PCB lamp plate (2), shape (3), Self-Clinching Standoffs (4) and box frame (5) five parts composition, and wherein, LED lamp pearl (1) is fixed on the PCB lamp plate (2); Shape (3) adopts aluminium alloy extrusions, and the section bar tow sides are manufactured with slot respectively, can place the PCB lamp plate (2) that has LED lamp pearl (1) in the slot; PCB lamp plate (2) in shape (3) and the slot constitutes single lamp bar jointly, adopts Self-Clinching Standoffs (4) that the lamp bar is fixed on the box frame (5), constitutes two-sided display screen.In addition, box frame (5) two ends are manufactured with dowel hole (7), use register pin (6) two or more box frames (5) can be combined closely more large-area display screen.
LED display with this structure, can realize double-sided display, increased display area, and because the box frame top is manufactured with dowel hole and register pin, only two or more display screens need be connected by register pin, can make the large area LED display screen, make making, maintenance and the replacing of LED display all very easy.
