Abstract
The present invention improves a kind of LED lamp panel applied to movie theatre, includes pcb board and LED particle, and multiple LED particle rectangular arrays are distributed in pcb board front, and pcb board is provided with the through-hole through front and back sides, multiple through-hole rectangular array distributions.In the present invention, pcb board is provided with the through-hole through front and back sides, can reduce blocking and reflection of the LED lamp panel to sound in LED movie theatre, avoid echogenicity, essentially identical so as to the sound effect heard in LED movie theatre different location；Since LED lamp panel reduces blocking and reflection to sound, thus resonance of the sound to LED lamp panel is decreased, avoids signal, connector loosening, guarantee that LED display is shown normally；Through-hole can make LED lamp panel front and back sides realize cross-ventilation, improve heat dissipation effect, reduce display screen internal temperature, avoid LED display colour cast serious.
Description
Technical field
The present invention relates to LED display technical field more particularly to a kind of LED lamp panels applied to movie theatre.
Background technique
LED lamp panel is provided in LED display.Existing LED lamp panel include pcb board, LED particle, IC device and
Connector, multiple LED particles are distributed in pcb board front, and IC device is mounted on pcb board reverse side, and it is anti-that connector is fixed on pcb board
Face.
Different according to the working method of LED display, IC device can have row driving IC device, column driving IC device and letter
Number processing IC device etc., and according to lamp plate size and LED particle quantity, every kind of IC number of devices has difference.Connector is used for
It is connect with pinboard, so that LED lamp panel is realized the connection of working power, working signal, connector quantity is not unique according to demand.
LED movie theatre is using LED display as display carrier.In actual use, due in LED movie theatre exist compared with
Big sound, sound largely can be stopped and be reflected by LED lamp panel in communication process, make the sound effect in movie theatre in different positions
Setting cannot be consistent or even echogenicity.Simultaneously as sound can make LED lamp panel resonate in communication process, for a long time
It under resonance, can fall off between connector and pinboard, power supply, signal patch loosening, and then LED display is caused to break down.
Also, as the LED display in LED movie theatre becomes greatly, the IC device in LED lamp panel also can be more and more, and fever also can
Increase, existing LED lamp panel heat dissipation is poor, causes display screen internal temperature excessively high, LED display colour cast is serious, reduces view
Feel effect.
Summary of the invention
It is a kind of applied to movie theatre the technical problem to be solved by the present invention is to provide according to above-mentioned the deficiencies in the prior art
LED lamp panel can be improved the sound effect in movie theatre, and power supply, signal patch stabilization, good heat dissipation effect.
Technical scheme is as follows:
A kind of LED lamp panel applied to movie theatre includes pcb board and LED particle, multiple LED particle rectangular array distributions
In the pcb board front, the pcb board is provided with the through-hole through front and back sides, multiple through-hole rectangular array distributions.
Further, through-hole described in LED particle and every a line described in every a line is interspersed up and down.
Further, each column LED particle and each column through-hole or so are interspersed.
Further, the pcb board reverse side is pasted with IC device, multiple IC device rectangular array distributions.
Further, through-hole described in IC device and every a line described in every a line is interspersed up and down.
Further, each column IC device and each column through-hole or so are interspersed.
Further, the pcb board reverse side is provided with connector.
Compared with prior art, the invention has the following beneficial effects: (1) pcb boards to be provided with the through-hole through front and back sides,
Blocking and reflection of the LED lamp panel to sound in LED movie theatre can be reduced, echogenicity is avoided, so as in LED movie theatre difference position
It is essentially identical to set the sound effect heard；(2) it since LED lamp panel reduces blocking and reflection to sound, thus decreases
Resonance of the sound to LED lamp panel avoids signal, connector loosening, guarantees that LED display is shown normally；(3) through-hole can
So that LED lamp panel front and back sides is realized cross-ventilation, improve heat dissipation effect, reduces display screen internal temperature, avoid LED display inclined
Color is serious.
Detailed description of the invention
Fig. 1 is the perspective view of embodiment.
Fig. 2 is the perspective view of another angle of embodiment.
Appended drawing reference
10-PCB plate, 11- through-hole, 20-LED particle, 30-IC device, 40- connector.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing
Step ground detailed description.
As depicted in figs. 1 and 2, embodiment provided by the invention, a kind of LED lamp panel applied to movie theatre, includes pcb board
10 and LED particle 20.
Multiple 20 rectangular arrays of LED particle are distributed in 10 front of pcb board, and pcb board 10 is provided with the through-hole through front and back sides
11, multiple 11 rectangular array of through-hole distributions.Every a line LED particle 20 and about 11 every a line through-hole are interspersed, each column LED
Particle 20 and each column through-hole 11 or so are interspersed.
10 reverse side of pcb board is pasted with IC device 30, multiple 30 rectangular array of IC device distributions.Every a line IC device 30 and every
About 11 a line through-hole is interspersed, and each column IC device 30 and each column through-hole 11 or so are interspersed.
10 reverse side of pcb board is provided with connector 40.
The above disclosure is only the preferred embodiments of the present invention, cannot limit right model of the invention certainly with this
It encloses, therefore equivalent changes made in accordance with the claims of the present invention, is still within the scope of the present invention.
