Penetrating LED display

Technical field

The present invention relates to the LED lighting device, in particular, a kind of penetrating LED display.

Background technology

In the prior art, because each LED lamp in process of production, various condition effect will inevitably there are differences, but each LED lamp can carry out stepping by the beam split color scanner, and beam split color separation precision is very high.

Because different clients are different to the accuracy requirement of each LED lamp, and also inequality to the use amount of each LED lamp, therefore, general lamp screen or display screen manufacturing factory after receiving customer order, buy the LED lamp to LED lamp manufacturer again.Because the LED lamp is unfixing relatively in storing process, shake easily, the collision etc. influence and damage, therefore, LED lamp manufacturer produces can not store the goods amount in a large number yet, lamp screen or display screen manufacturing factory are difficult to buy the LED lamp of same precision, therefore, the close LED lamp of class is generally bought by lamp screen or display screen manufacturing factory, because of the LED lamp of each class has chroma luminance difference, generally can directly not get very high lamp with these precision directly made screen after lamp screen manufacturer took these lamps, because human eye is very sensitive for the difference of colourity, if the lamp of different class is used in each zone, will " mosaic phenomenon " that just it has often been said the fragment of brick screen appear, in interregional formation brightness and colourity difference.

The convention of LED display industry is to do will fry lamp-promptly before the screen and the LED lamp back mixing of N class is stirred together realize whole even mixing, and its purpose is the difference between class is broken up, and does not exist monoblock irregular.Though but the way of doing has like this been eliminated the big-difference between the module, the obvious differenceization in the module between the LED lamp, the demonstration heterogeneity of whole screen, display effect is poor.And, making the processing of high-precision LED lamp beam split color separation, the stage of producing in LED display does not have due effect, causes the wasting of resources.Simultaneously, the lamp that different batches is fried, the mean value of its colourity and brightness is different, can not use with! Also increased the difficulty of producing.

Therefore, there is defective in prior art, needs to improve.

Summary of the invention

Technical matters to be solved by this invention is because the LED lamp of each class is evenly mixed, and causes each LED light emitting diode obvious difference in the LED display, shows heterogeneity, display effect is poor, and aspect difficulty such as daily use, management and assembling are strengthened.

Embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

Embodiment 1

As shown in Figure 1, present embodiment provides a kind of penetrating LED display, and described penetrating LED display comprises at least two PCB bars, as comprises PCB bar 101 and PCB bar 102.

In process of production, according to the material difference of LED wafer, can make the LED light emitting diode of different colours, the LED light emitting diode of different colours is produced respectively in batches, and, can adopt identical encapsulation, be made into identical shaped and big or small LED light emitting diode, the employing beam split color scanner of each LED light emitting diode of same color is carried out stepping, promptly can obtain the LED light emitting diode of different class of all kinds.

In PCB bar 101 and the PCB bar 102, be provided with the LED light emitting diode of at least two groups, each LED light emitting diode is the LED light emitting diode that adopts the beam split color scanner to obtain, and the LED light emitting diode of respectively organizing in each PCB bar is all linearly arranged, and the PCB bar of linearly arranging is when the penetrating LED display of assembly cost embodiment, very convenient, quick, and when being combined into conventional dot matrix arrangement LED display, array mode is simple.

In same PCB bar, perhaps for each PCB bar, each is organized the LED light emitting diode the identical LED light emitting diode of all kinds of quantity is set, and each is organized in the LED light emitting diode, and the arrangement mode of LED light emitting diode of all kinds is identical; And the distance that each can also be organized between the LED light emitting diode is made as equal; For example, in each group LED light emitting diode, 1 red LED light emitting diode, 1 green LED light emitting diode and 1 blue led light emitting diode are set all, and, each LED light emitting diode is all triangular in shape arranges, and, be made as the distance between each group LED light emitting diode equal; Perhaps, in each group LED light emitting diode, 2 red LED light emitting diodes, 1 green LED light emitting diode and 1 blue led light emitting diode are set all, and, each LED light emitting diode all is quadrilateral arranges, and, be made as the distance between each group LED light emitting diode equal.

Because the quantity of the color of each LED light emitting diode combined, combination is all identical with the shape of arranging in each group LED light emitting diode, and the LED light emitting diode of respectively organizing of LED display is the dot matrix arrangement; So, the LED display of composition is the LED display of rule, satisfies the requirement that is provided with of conventional LED display, meet the control and the display mode of prior art, and it is even that each organizes the LED light-emitting diode arrangement, and display effect is good.

In PCB bar 101, LED light emitting diode of all kinds is the LED light emitting diode of same minute gear selecting, promptly, all red LED light emitting diodes only adopt the LED light emitting diode of a branch gear selecting, all green LED light emitting diodes only adopt the LED light emitting diode of a branch gear selecting, and all blue led light emitting diodes also only adopt the LED light emitting diode of a branch gear selecting.
