Background technique
LED display is as a kind of electronic equipment, with its brightness is high, dynamic image display effect is good, failure is low, energy consumption
Less, the advantages such as long service life, display content multiplicity, the abundant, ratio of performance to price height of display mode, it is each to be widely used to each row
Industry.But LED display also will appear some fault conditions in the case where gradually increasing service life, and for example lamp has not worked just
It is common one of failure.Because of the needs usually carried, the design of LED screen itself, which will have, can be resistant to the firm of carrying
Property, it is not so easy to collide in the handling process, causes the LED lamp bead even damage of PCB pad, even a LED lamp is bad
Fall and also influences whether whole effect.
Existing technology has the following problems: 1, putting the display screen of spacing P2.5 or more, Pad off can pass through fly line
Maintenance.But fly line is exposed to have some potential safety problems in air, and fly line will affect the vision effect of entire display screen
Fruit, appearance are ugly；In addition the Pad off of large area, because required fly line makes fly line operation extremely difficult too much；2, spacing is put
P2.5 display screen below because spacing too it is small can not fly line operation, therefore completely new method for maintaining must be taken.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of repairing of LED display module lamp face PCB Pad off
Paper, including two layers of ultrathin flexible wiring board, one layer is lamp bead welding surface, and another layer is PCB welding surface；
Lamp bead welding surface is equipped with several evenly distributed lamp bead welding surface pads, passes through between adjacent lamps bead weld junction pad
Alignment is connected to column signal, and lamp bead welding surface pad is equipped with several equally distributed via holes one, and via hole one is located at each lamp bead
Welding surface pad foot position center；
PCB welding surface is equipped with several evenly distributed PCB welding surface pads, passes through row between adjacent PCB welding surface pad
Line connects right of way signal, and PCB welding surface pad is equipped with several equally distributed via holes two, and via hole two is located at each PCB welding
Face pad foot position center.
Technical effect: the utility model can cut the repairing paper of a big circle, greatly according to impaired region area when in use
Normal electric signal is conducted on repairing paper by the part of one circle, other regions are used as the substitution pad of impaired pad.
The technical solution that the utility model further limits is:
A kind of preceding LED display module lamp face PCB Pad off repairs paper, the diameter of via hole one and the via hole two
For 0.2mm~0.4mm.
A kind of preceding LED display module lamp face PCB Pad off repairs paper, repair paper with a thickness of 0.1mm.
A kind of preceding LED display module lamp face PCB Pad off repairs paper, and lamp bead welding surface and PCB welding surface are not
Front and back sides are distinguished, can be rotated by 90 ° as needed or 180 ° use, face use can also be overturn.
The beneficial effects of the utility model are:
(1) the utility model maintenance paper thickness there was only 0.1mm, be laid on impaired PCB in this way have substantially no effect on it is original
The thickness of pcb board, the lamp bead after repairing can be effectively ensured will not obviously be higher by other regions；
(2) the utility model can arbitrarily cut corresponding shape according to impaired area size, because it uses flexible wires
The production of road plate, therefore can satisfy plane screen paving, arc screen paving can also be met；
(3) the utility model can be adapted for big spacing, small spacing, indoor mould group, outdoor mould group, Local Damaged, sheet
The various occasions such as impaired, it is adaptable.

Specific embodiment
A kind of LED display module lamp face PCB Pad off provided in this embodiment repairs paper, and structure is as shown in Figs. 1-2, packet
Two layers of ultrathin flexible wiring board is included, one layer is lamp bead welding surface 1, and another layer is PCB welding surface 2.
Lamp bead welding surface 1 is equipped with several evenly distributed lamp bead welding surface pads 3, between adjacent lamps bead weld junction pad 3
It is connected to column signal by alignment 4, lamp bead welding surface pad 3 is equipped with several equally distributed via holes 1, and via hole 1 is located at
Each 3 foot position of lamp bead welding surface pad center.
PCB welding surface 2 is equipped with several evenly distributed PCB welding surface pads 6, passes through between adjacent PCB welding surface pad 6
Line 7 connects right of way signal, and PCB welding surface pad 6 is equipped with several equally distributed via holes 28, and via hole 28 is located at each
