As shown in the figure, the LED dot matrix display 1 is composed of a plurality of dot matrix LEDs 11 side by side spliced on a circuit board 12, and each dot matrix LED 1 comprises: a casing 111, an inner circuit board 112 and a plurality of The LED light-emitting chip 113 has a rectangular box structure. The top surface of the housing 111 is a light-emitting surface 1111, and a plurality of through-holes 1112 are arranged equidistantly in a dot matrix manner. The two through holes 1112 have a set spacing corresponding to the display resolution, and the smaller the set pitch is, the higher the display resolution is; and the rows of the inner circuit board 112 are provided with rows of pins 1121 for externally controlling the power supply; When assembled, the LED light-emitting chips 113 are disposed on the inner circuit board 112, and finally the inner circuit board 112 is placed in the housing 111, so that the LED light-emitting chips 113 are respectively disposed correspondingly. The position of the hole 1112 is fixed by injection molding. its The housing 111 is made by a general plastic injection molding technique, and the finished product is provided with a draft angle between the light-emitting surface 1111 and each side surface in order to smoothly remove the film, so that the area of the light-emitting surface 1111 is slightly The area of the bottom opening of the casing 111 is smaller than that of the casing 111 to be removed from the mold.
再請參閱第2圖,係為一般LED點矩陣顯示器組裝時的狀態示意圖。如圖中所示,拼接時,該等點矩陣LED 11係以該殼體111邊緣對齊的方式進行,由於該殼體111底面開口面積較大,致使拼接後造成該二相鄰二殼體的該等出光面頂面之間產生一細微的間隙(GAP),當焊接時的溫度使該殼體111及固定膠的體積膨脹,造成該間隙擴大而影響拼接時的平整度及間隔距離,特別是會產生影像移動時的跳動現象(或稱之為馬賽克效應)。再者,由於焊接時的該殼體111或固定膠的體積並非均勻地膨脹,造成設計人員及組裝人員在進行設計或組裝時,無法精確計算該二殼體111間的間隔距離,經常會造成顯示平面產生段差或是不平整等問題,這些問題長久以來一直困擾製造該LED點矩陣顯示器1的生產廠商。Referring to FIG. 2 again, it is a schematic diagram of a state in which a general LED dot matrix display is assembled. As shown in the figure, when splicing, the dot matrix LEDs 11 are aligned in the edge of the casing 111. Since the opening area of the bottom surface of the casing 111 is large, the two adjacent two casings are caused by splicing. A fine gap (GAP) is generated between the top surfaces of the light-emitting surfaces, and the temperature during the welding expands the volume of the casing 111 and the fixing glue, thereby causing the gap to expand and affecting the flatness and the spacing distance during the splicing, in particular It is a beating phenomenon (or called a mosaic effect) when an image moves. Moreover, since the volume of the casing 111 or the fixing glue is not uniformly expanded during welding, the designer and the assembler cannot accurately calculate the separation distance between the two casings 111 when designing or assembling, which often causes The display plane creates problems such as step differences or unevenness, which have long plagued manufacturers who manufacture the LED dot matrix display 1.
是以,本創作人有鑑於此,乃針對上述該殼體111之缺失深入加以研究、設計,經多方實驗改良後,終於設計出一種改良式殼體的結構,以在組裝後具有平整顯示面之LED點矩陣顯示器。Therefore, the present inventors have intensively studied and designed the above-mentioned missing of the casing 111, and after a plurality of experiments, finally designed an improved casing structure to have a flat display surface after assembly.
