Embodiment：As shown in Figs. 1-3, the present invention provides a kind of technical solution, a kind of small space distance LED display screen, including LED
Lamp group 1, babinet 2, fixed screw 3, the LED light group 1 are fixedly connected on 2 front end of babinet, and the LED light group 1 and babinet 2 are adopted
With interference fit, the babinet 2 is equipped with fixed screw 3, and the babinet 2 and fixed screw 3 are flexibly connected, the LED
Lamp group 1 includes pcb board 21 and is arranged in the positive several LED light tube 22 of pcb board 21, and the LED light tube 22 is rectangle
Array distribution, 21 back side of pcb board are integrated circuit welding surface 23, and pyromagnetic heat dissipation is also had additional on the integrated circuit welding surface 23
Device 24；2 side of the babinet is additionally provided with thermal vias；The babinet 2 includes shell 201, screw 202, bottom case
203, heat emission hole 204, connecting terminal 205, indicator light 206,201 centre position of shell is equipped with bottom case 203, described
Shell 201 and bottom case 203 are flexibly connected by screw 202, and the bottom case 203 is equipped with heat emission hole 204, the bottom
Shell 203 and heat emission hole 204 are integrated, and about 203 bottom case is equipped with connecting terminal 205, the bottom case 203
It is gap-matched with connecting terminal 205, the bottom case 203 is equipped with indicator light 206, and the bottom case 203 is equipped with four
A connecting terminal 205, the LED light group 1 and connecting terminal 205 are electrically connected by conducting wire, and the LED light group 1 is rectangle
Structure, 2 length of babinet, height, width be respectively 400,300,66mm, the babinet 2 is pack alloy, is not easy
Damage, the LED light group 1 are equipped with mask.
The size of each LED light tube 22 is less than or equal to 1.0mm*1.0mm, adjacent two LED in the present invention
Distance is less than 1mm between the edge of luminous tube 22.Point spacing is important an one of technical parameter index of LED display,
Point spacing is to reflect pixel density from the distance between pixel two-by-two, put spacing and pixel density be display screen physical attribute；
Information capacity is then the unit of quantity of the disposable shown information carrying capacity of unit area pixel density, and point spacing is got over
Small, pixel density is higher, and unit area can disposably show that information capacity is more.Small space distance LED display screen can be realized same
Higher resolution picture is shown under equidimension, this performance becomes consumer's household for LED display product and shows that equipment is great
Meaning, and it have both high colour gamut, high refresh rate, without ghost, low-power consumption the features such as, it is aobvious to parlor screen to meet very much user at present
Show the trend of effect requirements.
Since spacing is reduced between lamp group, more LED lamp beads are installed on unit area, small space distance LED display screen is to technique
It is required that higher, and radiate, circuit the problems such as to solve also to spend costs more more than big spacing product.The present invention exists
