The technological means, the creation characteristic that realize in order to the present invention, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the present invention further.
With reference to Fig. 1, layering LED display, comprises EL diplay array, and EL diplay array comprises at least two group EL diplay subarrays, i.e. the first EL diplay subarray 11, second EL diplay subarray 12.Two-layer arrangement before and after first EL diplay subarray 11 and the second EL diplay subarray 12 are divided into obviously also can be the mode of being arranged above and below.EL diplay array is divided at least two groups tandem EL diplay subarray and effectively can reduces electroluminescence point arrangement quantity on same thickness (or height), effectively can reduce production difficulty.EL diplay subarray can also be allowed to be embedded in electroluminescence laminar substrate.Electroluminescent layer substrate peripheral can be cylindricality, spherical, polygon or other shapes.
Electroluminescence point can be LED, can also be electroluminescent powder point, can also be the region, two electrode intersections of a slice electroluminescent powder.
When electroluminescence point is electroluminescent powder point, electroluminescence point can be itself be that the electroluminescent powder of spot distribution is determined, also can be determined by the cross-point of electrode.The alternating share of front electrode and rear electrode can determine an electroluminescence point.
Electroluminescence point in EL diplay array adopts LED element, or directly adopts electroluminescent layer.Electroluminescent layer can be the electroluminescent powder by voltage stimulated luminescence.The color of the electroluminescence point that the color of the electroluminescence point that the first EL diplay subarray 11 adopts and the second EL diplay subarray 12 adopt is inconsistent.This design can so that electroluminescence point control and be convenient to produce.
In order to produce abundant color, in actual production, electroluminescence array of display can adopt three groups of EL diplay subarrays, namely from the first EL diplay subarray 11, second EL diplay subarray 12, the 3rd EL diplay subarray 13 of A-P hierarchal arrangement.First EL diplay subarray 11, second EL diplay subarray 12, the 3rd EL diplay subarray 13, adopt the electroluminescence point of the different color in three primary colours respectively, the electroluminescence point color in each group EL diplay subarray is preferably consistent.So that the picture that display color is abundant.The electroluminescence point of the different color in three primary colours can be red, green, blue three colour field photoluminescence point.Also can be utilize other forms of three primary colours, adopt the electroluminescence point forming other forms of three primary colours.
Layering LED display also comprises electroluminescence laminar substrate, and EL diplay array arrangement is on electroluminescent layer substrate.Electroluminescence laminar substrate comprises at least two-layer electroluminescent layer submounts, namely at least comprises the first electroluminescent layer submounts 21, second electroluminescent layer submounts 22.In tandem, the first electroluminescent layer submounts 21 adopts transparent material for first electroluminescent layer submounts 21 and the second electroluminescent layer submounts 22.First EL diplay subarray 11 is arranged on the first electroluminescent layer submounts 21, and the second EL diplay subarray 12 is arranged on the second electroluminescent layer submounts 22.By arranging electroluminescent layer submounts as carrier for the EL diplay subarray of EL diplay array, reduce production difficulty further, and allow to increase electroluminescence point arrangement density, to increase pixel.
In order to produce abundant color, in actual production, electroluminescence laminar substrate can adopt three layers of electroluminescent layer submounts, i.e. tandem first electroluminescent layer submounts 21, second electroluminescent layer submounts 22, the 3rd electroluminescent layer submounts 23.First electroluminescent layer submounts 21, second electroluminescent layer submounts 22 adopts transparent material respectively.First electroluminescent layer submounts 21, second electroluminescent layer submounts 22, the 3rd electroluminescent layer submounts 23 are loaded with respectively the first EL diplay subarray 11, second EL diplay subarray 12, the 3rd EL diplay subarray 13.The front of the first electroluminescent layer submounts 21 is also covered with a transparent protective layer 3, so that protection the first EL diplay subarray 11.While reduction production difficulty, permission increase electroluminescence point arrangement density, so that the picture that display color is abundant.
