Description

A kind of arc surface LED display screen

Technical field

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

Background technology

In the prior art, because each LED lamp in process of production, various condition effect will inevitably there are differences.

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 make screen will fry lamp before, promptly the LED lamp back mixing of N class is stirred together and realizes all evenly mixing, and its purpose is, the difference between class is broken up, with the unevenness of elimination monoblock.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, like this, the difficulty of also increased production, producing and repairing again.

The display surface of LED display is generally a planar rectangular, and therefore the LED display technique also is included into flat pannel display (FPD:Flat Panel Display) technology.Along with the appearance of LED full color display, the large display screen engineering development is rapid, and its display surface no longer is confined to a plane, and in many application scenarios, its display surface is required to make arc surfaced.In the prior art, arc surface LED display screen generally all adopts the cambered surface pcb board, complex structure, and difficulty of processing is big, and assembling is difficult.

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

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 arc surface LED display screen, and the present embodiment arc surface LED display screen can be made up of one or more arc surface LED modules, and wherein, each arc surface LED module comprises an arc surface panel 104 and some LED unit 101.

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.

For example, in arbitrary arc surface LED module of forming this example arc surface LED display screen, arbitrary LED unit 101 comprises one or more LED light emitting diodes, each LED light emitting diode is the LED light emitting diode that adopts the beam split color scanner to obtain, and, LED light emitting diode of all kinds is the LED light emitting diode of same minute gear selecting, promptly, in the same arc surface LED module, 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.

Because LED light emitting diode of all kinds adopts identical branch gear selecting respectively, therefore, the brightness of the LED light emitting diode of same color is identical, consistent wavelength, encapsulation is identical, shape is identical and big or small identical; Described consistent wavelength refers to, and each LED light emitting diode color that people's naked eyes are seen in a certain wavelength coverage is identical, promptly can think the consistent wavelength of all the LED light emitting diodes in wavelength coverage.

And the arrangement mode of each LED unit 101 is identical, for example, in each LED unit 101,1 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; Perhaps, in each LED unit 101,2 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 and arranges.

Because, the quantity of the color of each LED light emitting diode combined, combination is all identical with the shape of arranging in each LED unit 101, and, in the same arc surface LED module, the LED light emitting diode that each color is identical adopts the LED light emitting diode of same minute gear selecting, therefore, make the arc surface LED module of composition and the arc surface LED display screen of forming by each arc surface LED module, when display graphics, literal, letter, animation etc., show homogeneous, display effect is good.
