On the one LED submounts 21, the 2nd LED submounts 22, the 3rd LED submounts 23, be loaded with respectively a LED and show that subarray 11, the 2nd LED show that subarray 12, the 3rd LED show subarray 13. The front of the one LED submounts 21 is also covered with a transparent overcoat 3, so that protection the one LED shows subarray 11. In reducing production difficulty, allowing to increase LED arrangement of elements density, so that the abundant picture of display color.
The front that is positioned at the LED submounts at relative rear is furnished with rear electrode 41 (conducting wire), and the rear that is positioned at the LED submounts in relative front is furnished with front electrode 42 (conducting wire). Before and after two pins of LED element, arrange, access respectively rear electrode and front electrode. Front electrode 42 can be set on overcoat. Front electrode 42 and rear electrode 41 forms controls arrays, under the control of external control circuit and then control the luminous situation of each LED element, thereby realizes the control to imaging pixel. Be conducive to like this simplify the production technology of controlling array. Front electrode 42 all adopts transparency electrode, and the rear electrode on a LED submounts 11, the 2nd LED submounts 12 adopts transparency electrode, so that form better display effect. Rear electrode 41 on the 3rd LED submounts 23 can not adopt transparency electrode.
In order further to reduce production difficulty, a pin of LED element is fixedly attached to rear electrode 41 (or front electrode), and another pin is crimped on front electrode 42 (or rear electrode), to simplify production technology. In order to ensure good electrically contacting, in two pins of LED element, at least one is for having flexible pin, so that keep good contact by rear electrode 41 or the front electrode 42 of elasticity and pressing. Or rear electrode or the employing of front electrode of carrying out pressing with the pin of LED element have flexible or flexible transparency electrode, so that carry out good contact with the pin of LED element in pressing process.
LED submounts can adopt flexible transparent material, has flexible LED stereoscopic display screen to generate. In order to adapt to flexible demand, the electrode that connects LED element in LED array of display can adopt wire, such as filamentary silver, copper wire etc.
The LED submounts place in LED element front is provided with the astigmatic piece 51 with astigmatism effect, all uses thereby the light that LED element is launched is soft. The area of astigmatism piece 51 is greater than the longitudinal section area of LED element, so that the area of single pixel is larger, and then improves display effect. Astigmatism piece 51 can be the part matsurface that LED submounts produces, and can be also the matsurface producing on front electrode on LED submounts or rear electrode.
LED element in tandem each LED demonstration subarray can overlappingly be arranged, and also can misplace and arrange. In the time that LED element can overlappingly be arranged, the area of astigmatic piece 51 is greater than the longitudinal section area of LED element, and the light that can effectively avoid the LED element in front to produce the LED element at rear causes and blocks. Astigmatic piece 51 can play the effect that three primary colours are mixed in addition. The area of astigmatism piece 51 can be that area progressively increases from front to back, blocks avoiding. The area of astigmatism piece 51 can be that area progressively reduces from front to back, three primary colours is mixed promoting.
LED is shown to the method that subarray is embedded in described LED substrate is, LED submounts adopts the thermosets that not yet carries out heat cure. This thermosets should be transparent material after heat cure supplies. First each LED is shown to subarray is arranged on each layer of LED submounts, then each layer of LED submounts stacked, put into mould and heat, carry out heat cure. And then obtain LED show subarray be embedded in the LED stereoscopic display screen in LED substrate. So the gap between the LED submounts of LED substrate can reduce, and even disappears. Also can consider curing materials or the curing mode of other cured form, such as photocuring.
More than show and describe general principle of the present invention and principal character advantage of the present invention. The technical staff of the industry should understand the present invention and not be subject to the restriction of above-mentioned using method; that in above-mentioned using method and description, describes just says principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall into the claimed scope of the present invention in the claimed scope of the invention and defined by appending claims and equivalent thereof.
