Abstract
The invention provides a method for repairing a damaged light of an LED display screen. The method includes the following steps that S1, a heat insulation film is manufactured to cover the LED display screen, and the damaged light is exposed out of the heat insulation film; S2, a heating device is used for heating the damaged light and enables solder tin at the damaged light to be melt, the damaged light is taken down from the LED display screen, and a new LED light is installed. The heat insulation protective film is stuck to the periphery of the damaged light of the LED display screen, in the process of heating and replacing the damaged light through the heating device, good lights around the damaged light will not be affected by high temperature of the heating device and will not yellow, and the problem that the light beads of a small-interval LED display screen are affected by high temperature and yellow after the LED display screen is repaired is resolved. The method is easy to operate and implement.
Description
Technical field
The present invention relates to LED and keep in repair field, more specifically, relate to the bad lamp method for maintaining of a kind of LED display.
Background technology
LED display have display area large, brightness is high, bright in luster, easily assembled, the advantages such as space utilization factor is high, maintenance cost is low, apply more and more extensive in the society of Modern Information based.But before because LED display pixel pitch more greatly, closely watches the technical bottlenecks such as picture particle sense is strong, fail to enter indoor middle and high end mainstream applications.In recent years along with technical development, semiconductor fabrication process reached its maturity, and make LED show dot spacing more and more less, resolution is more and more higher, and Small Distance LED display has become a kind of inevitable development trend.Industry is referred to as Small Distance LED display below P2.5 product traditionally, and its maximum advantage is the natural reality of the completely seamless and display color of display screen.
Along with entering the market in enormous quantities of Small Distance LED screen, product after sale and safeguard it is also an important problem, the especially maintenance of lamp plate, at present or a common fault of industry, the method for maintaining that neither one is more ripe.Due to the lamp plate lamp pearl arrangement very dense of Small Distance LED, very difficult flatiron reaches lamp pearl gap to the heating of lamp base pad, and bad lamp is taken off.Relatively more conventional method blows down bad lamp with heat gun, after the lamp pearl changed, reusable heat air pressure gun blows in hot weld, a problem is there will be in this process, scolding tin could be melted because the temperature of heat gun generally will be adjusted to 250 degrees Celsius even higher, so high temperature can be given a piece of bad advice lamp pearl heat damage originally good around lamp, similarly be scorched the same, there will be the phenomenon of yellowing.Many times there will be the problem having occurred the yellowing of a sheet of area lights pearl because keeping in repair a bad lamp, losing more than gain.
Summary of the invention
The invention provides the bad lamp method for maintaining of a kind of LED display, avoid damaging other LED do not damaged when the bad lamp of maintenance LED display.
In order to reach above-mentioned technical matters, technical scheme of the present invention is as follows:
The bad lamp method for maintaining of a kind of LED display, comprises the following steps:
S1: making thermal isolation film is covered LED display and lamp of giving a piece of bad advice exposes from thermal isolation film;
S2: use heating arrangement it to be taken off and the LED more renewed from LED display the heating of bad lamp.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
In LED display, insulation protection film is sticked around bad lamp in the present invention; adding in the process of hot swap with heating arrangement to bad lamp; the lamp not having to damage around bad lamp would not the yellowing by the temperatures involved of heating arrangement; solve Small Distance LED display maintenance back light pearl because the problem of yellowing by high temperature, and the method simple to operate, be easy to realize.

Embodiment
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent;
In order to better the present embodiment is described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product;
To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.
Below in conjunction with drawings and Examples, technical scheme of the present invention is described further.
Embodiment 1
As shown in Figure 1, the bad lamp method for maintaining of a kind of LED display, comprises the following steps:
S1: making thermal isolation film is covered LED display and lamp of giving a piece of bad advice exposes from thermal isolation film;
S2: use heating arrangement it to be taken off and the LED more renewed from LED display the heating of bad lamp.
In the present embodiment, before S1, also comprise the step of the bad lamp found out in LED display.
The process finding out the bad lamp in LED display is as follows:
Make LED display work, if arbitrary LED is often bright or do not work, namely judge that this LED is damaged.
In the present embodiment, the manufacturing process of thermal isolation film is as follows:
According to number and the position of the bad lamp found out, utilize heat-barrier material and produce thermal isolation film according to the size of LED display, ensureing that bad lamp exposes from thermal isolation film when this thermal isolation film covers in LED display, the lamp of normal display is coating to be covered.
As shown in Figure 2, three pieces of LED display, wherein light blockage represents the LED 1 not having to damage, and dark blockage represents bad LED 2, and the bad lamp quantity of every block LED display and position are all uncertain, and in Fig. 2, the 1st piece of LED display has gone bad 1 LED; 2nd piece of LED display has gone bad 2 LED; 3rd piece of LED display has gone bad 3 LED.Stick insulation protection film to these 3 pieces of LED display when maintenance; as shown in Figure 3; grid of dashed lines shape region be high temperature resistant, heat insulation diaphragm 3, the LED 1 damaged that do not have around bad LED 2 is all covered, only the position of bad LED 2 is exposed.The making of insulation protection film does corresponding adjustment according to the position of bad lamp and quantity difference; the material of insulation protection film can with heat-barrier materials such as thermal insulating paper or glass fibre cotton plates; require ability 450 celsius temperature, the material of light and handy, the easy processing of choosing as far as possible.
The detailed process of step S2 is as follows:
Blow facing to the bad lamp place of having pasted thermal isolation film LED display with heating arrangement, bad lamp is taken off after scolding tin melts, change the normal LED lamp bead of identical type, again with the original position of heating devices heat bad lamp until scolding tin melt, the normal LED lamp bead of identical type is welded on the original position of bad lamp.Use heat gun as heating arrangement in the present embodiment.
The corresponding same or analogous parts of same or analogous label;
Describe in accompanying drawing position relationship for only for exemplary illustration, the restriction to this patent can not be interpreted as;
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All any amendments done within the spirit and principles in the present invention, equivalent to replace and improvement etc., within the protection domain that all should be included in the claims in the present invention.
