Problems solved by technology

The current unit board is made of plastic injection molding. The ribs between the lamp bead hole and the lamp bead hole on it cannot be designed too narrow due to the injection molding conditions, which hinders the distance between the lamp bead and the lamp bead. Resulting in low pixel LED display
And because the shell of each unit module is a rectangular box made of metal materials, the rectangular box is large in size, heavy in weight, and cannot be folded, which is not conducive to movement, and it is inconvenient to transport and install.

Embodiment Construction

[0014] figure 1 , Paste the LED lamp bead (2) on the FPC (4) by patching. figure 2 , fine steel wires (8) are provided on the back FPC (4) of the independent unit module. image 3 , Paste the LED lamp beads (2) on the FPC (4) and package them with thermally conductive soft silicone (3) to make a unit module. The driver (1) of the free-standing unit module is bolted to the top or bottom of the module. A T-shaped or mushroom-shaped fixing mechanism (5) is provided on the back of the unit module, and the soft LED display screen is fixed on the fixing frame by the fixing mechanism (5) when it needs to be finalized. Figure 4 , there are fast locks (7) and locking holes (6) on the periphery of the combined unit module. When two combined unit modules are connected, the locking block (7) of the unit module is inserted into the into the locking hole (6) of another unit module, and then use the fixing mechanism (5) on the back of the unit module to fix the SMD LED display on the fi...

Abstract

The utility model relates to a surface mount type LED (light emitting diode) display screen. LEDs (2) are attached to FPCs (flexible printed circuit) (4) in a surface mount manner, encapsulated with heat-conducting soft silica gel (3) and molded into unit modules. The unit modules of the surface mount type LED can be classified as independent type unit modules and combination type unit modules. Thin wires (8) are arranged on the FPCs on the backs of the independent type unit modules, and drivers (1) of the independent type unit modules are fixed at the top or bottom of the modules through bolts; and drivers of the combination type unit modules are designed to be of independent forms, the combination type unit modules are connected with the drivers through leading wires, and locking blocks (7) and locking holes (6) are arranged on the peripheries of the combination type unit modules. When two combination type unit modules are connected, the locking block (7) of one of the two unit modules is inserted into the locking hole (6) of the other unit module. T-shaped or mushroom-shaped fixing mechanisms (5) are arranged on the backs of the unit modules, so that when molding is requried, the fixing mechanisms (5) can be used for fixing the flexible LED display screen on a fixing bracket.

Description

technical field [0001] The invention belongs to the technical field of electronic imaging, in particular to a patch type LED display screen. Background technique [0002] The current LED display screen is assembled by display unit modules. The lamp beads on the PCB board of each unit module are plugged in by plug-in, and the PCB board is fixed on the unit board. The current unit board is made of plastic injection molding, and the ribs between the lamp bead hole and the lamp bead hole on it cannot be designed too narrow due to the injection molding conditions, which hinders the distance between the lamp bead and the lamp bead. Resulting in low pixel LED display. And because the shell of each unit module is a rectangular box made of metal material, because the rectangular box has a large volume, heavy weight, and cannot be folded, it is not conducive to moving, and it is also inconvenient to transport and install. Contents of the invention [0003] The purpose of the prese...
