Description
本發明係關於一種顯示單元，尤指一種模組化之LED顯示單元。本發明還包括以該LED顯示單元構成之LED顯示裝置。The present invention relates to a display unit, in particular to a modular LED display unit. The present invention also includes an LED display device composed of the LED display unit.
一般拼接式LED顯示裝置是利用複數個小尺寸之LED顯示模組兩兩拼接，進而構成所需之整體結構。然而，當利用前述方式拼接成具有特定角度（例如相接之二顯示面為直角）之轉角顯示裝置時，該些LED顯示模組於轉角部位之拼接難度較高，容易造成製造時間及成本大幅增加。此外，當位於轉角部位之兩個LED顯示模組左右拼接時，也容易出現兩個LED顯示模組於拼接處之相鄰LED元件之間距明顯大於單一LED顯示模組上之LED元件之設置間距之問題，導致轉角顯示裝置於轉角拼接處之亮度小於其他位置之亮度，進而產生黑線等顯示缺陷。如此一來，對觀看者而言將產生不佳之視覺體驗。Generally, a spliced LED display device uses a plurality of small-sized LED display modules to be spliced in pairs to form the required overall structure. However, when the above-mentioned method is used to splice into a corner display device with a specific angle (for example, two connected display surfaces are at a right angle), the splicing of these LED display modules at the corner is more difficult, which can easily lead to a significant increase in manufacturing time and cost. Increase. In addition, when two LED display modules located at a corner are spliced left and right, it is easy to find that the distance between adjacent LED elements of the two LED display modules at the splicing point is significantly larger than the installation distance of the LED elements on a single LED display module. This problem causes the brightness of the corner display device at the corner joint to be lower than the brightness at other locations, resulting in display defects such as black lines. As a result, it will produce a poor visual experience for the viewer.

The adjacent side 13 is mainly used for splicing with another LED display unit 1, and the number of the adjacent side 13 will be adjusted according to different design requirements. For example, the base 10 may include only a single adjoining side 13 for adjoining another LED display unit 1 , or the base 10 may include more than two adjoining sides 13 for adjoining different LED display units 1 respectively.
各鄰接側13相對於第一面11呈一斜角C，以利於鄰接另一LED顯示單元1之底座10。在本發明之一實施例中，前述斜角C不小於45度，例如可設計介於45度至135度之間，使得本發明之LED顯示單元1藉由鄰接側13與另一LED顯示單元1拼接時，可相應形成具有特定角度（例如直角）或呈曲面之顯示單元組合，但本發明不以此為限。Each adjacent side 13 forms an oblique angle C relative to the first surface 11 to facilitate adjoining the base 10 of another LED display unit 1 . In one embodiment of the present invention, the aforementioned bevel angle C is not less than 45 degrees, for example, it can be designed to be between 45 degrees and 135 degrees, so that the LED display unit 1 of the present invention communicates with another LED display unit through the adjacent side 13 1. When splicing, a combination of display units with a specific angle (such as a right angle) or a curved surface can be formed, but the invention is not limited to this.
如圖3所示，在本發明中，底座10之各鄰接側13包括至少一穿孔131。各穿孔131可為長條形孔，且各穿孔131之長度延伸方向大致平行於第一面11。穿孔131主要用以供容置LED顯示模組20之相應部件，且穿孔131之設置數量會依設計需求不同而調整。舉例來說，鄰接側13可以僅包括單一穿孔131，或者鄰接側13可以包括兩個以上穿孔131；而當至少一穿孔131為複數個時，該些穿孔131係沿著平行於第一面11之一直線間隔排列。As shown in FIG. 3 , in the present invention, each adjacent side 13 of the base 10 includes at least one through hole 131 . Each through hole 131 may be a long hole, and the length direction of each through hole 131 is substantially parallel to the first surface 11 . The through holes 131 are mainly used to accommodate corresponding components of the LED display module 20, and the number of the through holes 131 will be adjusted according to different design requirements. For example, the adjoining side 13 may include only a single through hole 131 , or the adjoining side 13 may include more than two through holes 131 ; and when at least one through hole 131 is a plurality, the through holes 131 are parallel to the first surface 11 arranged in straight lines.
以下請一併參考圖1及圖4，其中圖4為本發明之LED顯示單元之局部剖視圖。如圖1及圖4所示，LED顯示模組20設置於底座10，且LED顯示模組20包括電路板21及設置於電路板21之複數LED元件22。在本發明中，複數LED元件22係採用矩陣陣列規則地排列，且複數LED元件22中之任意二個相鄰LED元件22之間係保持相同之LED設定間距A。前述由複數LED元件22所組成之矩陣陣列，將隨著複數LED元件22之設置數量不同而改變其陣列大小。此外，在本發明中，定義複數LED元件22中最靠近電路板21之邊緣211之任一LED元件為邊緣LED元件22a。Please refer to FIG. 1 and FIG. 4 together below. FIG. 4 is a partial cross-sectional view of the LED display unit of the present invention.

In addition, in the present invention, any LED element closest to the edge 211 of the circuit board 21 among the plurality of LED elements 22 is defined as the edge LED element 22a.
當LED顯示模組20設置於底座10時，電路板21之邊緣211伸入至少一穿孔131內，因此隨著電路板21相對於底座10移動，電路板21之邊緣211位於至少一穿孔131內之位置也會隨之改變。也就是說，藉由前述至少一穿孔131之設置以利於改變電路板21相對於底座10之位置。在本發明之一實施例中，電路板21之邊緣211可包括截角部212，當邊緣211位於至少一穿孔131內時，藉由截角部212使得邊緣211不會凸出至少一穿孔131，以利於本發明之LED顯示單元1藉由鄰接側13與另一LED顯示單元1之鄰接側13拼接。When the LED display module 20 is disposed on the base 10, the edge 211 of the circuit board 21 extends into at least one through hole 131. Therefore, as the circuit board 21 moves relative to the base 10, the edge 211 of the circuit board 21 is located in at least one through hole 131. The position will also change accordingly. That is to say, the position of the circuit board 21 relative to the base 10 is facilitated by the arrangement of the at least one through hole 131 . In one embodiment of the present invention, the edge 211 of the circuit board 21 may include a truncated portion 212. When the edge 211 is located within the at least one through hole 131, the truncated portion 212 prevents the edge 211 from protruding from the at least one through hole 131. , to facilitate the LED display unit 1 of the present invention to be spliced with the adjacent side 13 of another LED display unit 1 through the adjacent side 13 .

在本發明之一實施例中，本發明之LED顯示單元1更包括至少一磁鐵件40。至少一磁鐵件40鄰近底座10之第二面12而設置。前述供LED顯示單元1設置之物件同樣可採用可被磁力吸引之材料製成。因此，當本發明之LED顯示單元1需要設置於前述物件上時，將底座10之第二面12靠近該物件，即可藉由至少一磁鐵件40對該物件產生磁吸力，以快速且簡易達到輔助固定之效果。In one embodiment of the present invention, the LED display unit 1 of the present invention further includes at least one magnet 40 . At least one magnet component 40 is disposed adjacent to the second surface 12 of the base 10 . The aforementioned objects for installing the LED display unit 1 can also be made of materials that can be magnetically attracted.

以下請一併參考圖4至圖6C，其中圖5為本發明之LED顯示裝置之第一實施例之示意圖，圖6A至圖6C為本發明之LED顯示裝置之第一實施例分別選用具有不同LED設定間距之LED顯示模組之剖視圖。如圖5所示，在以下實施例中，本發明之LED顯示裝置300係以兩個相同之LED顯示單元1相互拼接為例來說明相關技術內容，其中各LED顯示單元1之底座10僅包括單一鄰接側13且採用45度之斜角，進而拼接出具有90度直角之轉角顯示裝置，但本發明不以此為限。Please refer to FIGS. 4 to 6C below. FIG. 5 is a schematic diagram of the first embodiment of the LED display device of the present invention. FIGS. 6A to 6C are respectively selected to have different characteristics of the first embodiment of the LED display device of the present invention. Cross-sectional view of an LED display module with set LED spacing. As shown in Figure 5, in the following embodiments, the LED display device 300 of the present invention takes two identical LED display units 1 spliced to each other as an example to illustrate the relevant technical content, in which the base 10 of each LED display unit 1 only includes A single adjacent side 13 adopts an oblique angle of 45 degrees, thereby splicing a corner display device with a right angle of 90 degrees, but the present invention is not limited to this.
如圖5所示， LED顯示單元1係基於對稱面P與另一相同之LED顯示單元1拼接，以構成本發明之LED顯示裝置300。對稱面P係位於兩個LED顯示單元1之間，使得兩個LED顯示單元1基於對稱面P形成結構對稱。由於兩個LED顯示單元1之底座10之斜角均為45度，且於兩個LED顯示單元1彼此拼接時，將其中一個LED顯示單元1之鄰接側13與另一LED顯示單元1之鄰接側13形成面接觸，使得二個LED顯示單元1之間會呈現90度之夾角，該夾角為斜角之2倍；此時，兩個LED顯示單元1之鄰接側13均位於對稱面P上。然而，在本發明之另一實施例中，將底座10之斜角為45度之兩個LED顯示單元1基於對稱面P彼此拼接時，若其中一個LED顯示單元1之鄰接側13與另一LED顯示單元1之鄰接側13僅形成點接觸，將使得二個LED顯示單元1之間會呈現大於90度之夾角；此時，兩個LED顯示單元1之鄰接側13會分別與對稱面P呈另一夾角。據此，本發明之LED顯示裝置300可依據不同設計需求，改變相鄰二個LED顯示單元1所形成之夾角，進而構成具有特定角度之轉角或曲面之顯示裝置。As shown in FIG. 5 , the LED display unit 1 is spliced with another identical LED display unit 1 based on the symmetry plane P to form the LED display device 300 of the present invention. The symmetry plane P is located between the two LED display units 1, so that the two LED display units 1 form structural symmetry based on the symmetry plane P. Since the bevel angles of the bases 10 of the two LED display units 1 are both 45 degrees, and when the two LED display units 1 are spliced to each other, the adjacent side 13 of one LED display unit 1 is adjacent to the other LED display unit 1 The side 13 forms a surface contact, so that the two LED display units 1 will have an included angle of 90 degrees, which is twice the oblique angle; at this time, the adjacent sides 13 of the two LED display units 1 are located on the symmetry plane P . However, in another embodiment of the present invention, when two LED display units 1 with an oblique angle of 45 degrees on the base 10 are spliced to each other based on the symmetry plane P, if the adjacent side 13 of one LED display unit 1 is connected to the other The adjacent sides 13 of the LED display units 1 only form point contact, which will cause the angle between the two LED display units 1 to be greater than 90 degrees. At this time, the adjacent sides 13 of the two LED display units 1 will be in contact with the symmetry plane P respectively. Another angle. Accordingly, the LED display device 300 of the present invention can change the angle formed by two adjacent LED display units 1 according to different design requirements, thereby forming a display device with a specific angle of corner or curved surface.
如圖4至圖6C，所示，在設計上，本發明之LED顯示單元1可基於LED顯示模組20之LED設定間距A，改變電路板21相對於底座10之適當設置位置，以調整複數LED元件22中之任一邊緣LED元件22a與對稱面P之最短距離。在本發明之一實施例中，若假設LED設定間距為A，則任一邊緣LED元件22a與對稱面P之最短距離約為(A±5%)/2。由此推知，在相同前提之下，當前述兩個LED顯示單元1彼此拼接時，其中一個LED顯示單元1中之任一邊緣LED元件22a與另一LED顯示單元1中對應相鄰之邊緣LED元件22a之最短間隔距離則約為A±5%。據此，本發明之LED顯示裝置300即使在相鄰二個LED顯示單元1所形成之夾角處，也能使相鄰二個邊緣LED元件22a之間距與LED顯示單元1之LED設定間距A幾乎保持一致，以避免因間距差異而產生黑線或亮線等顯示缺陷，提供給觀看者較佳之視覺體驗。As shown in FIGS. 4 to 6C , in terms of design, the LED display unit 1 of the present invention can change the appropriate position of the circuit board 21 relative to the base 10 based on the LED setting pitch A of the LED display module 20 to adjust the complex number. The shortest distance between any edge LED element 22a of the LED element 22 and the symmetry plane P. In one embodiment of the present invention, assuming that the LED setting pitch is A, the shortest distance between any edge LED element 22a and the symmetry plane P is approximately (A±5%)/2. It can be deduced from this that under the same premise, when the two LED display units 1 are spliced to each other, any edge LED element 22a in one LED display unit 1 will be in contact with the corresponding adjacent edge LED in the other LED display unit 1. The shortest distance between components 22a is approximately A±5%. Accordingly, the LED display device 300 of the present invention can make the distance between two adjacent edge LED elements 22a almost equal to the LED setting distance A of the LED display unit 1 even at the angle formed by two adjacent LED display units 1. Keep it consistent to avoid display defects such as black lines or bright lines due to spacing differences, and provide viewers with a better visual experience.
依據設計需求不同，LED顯示單元1會採用具有不同LED設定間距之LED顯示模組20。如圖6A至圖6C所示，假設LED顯示單元1之LED顯示模組20所採用之LED設定間距分別為5mm、3mm及1mm，但均採用相同規格之底座10。當LED設定間距為5mm時，LED顯示模組20之電路板21之邊緣211僅需伸入穿孔131一小段距離，即可達到前述邊緣LED元件22a與對稱面P之最短距離（約為2.5mm；因此，當兩個LED顯示單元1拼接後，相鄰二個邊緣LED元件22a之間距也大致為5mm。隨著所採用之LED設定間距越小，LED顯示模組20之電路板21之邊緣211也相對需要伸入穿孔131更多距離，才能達到前述邊緣LED元件22a與對稱面P之最短距離之要求（分別約為1.5mm及0.5mm）。而為了避免電路板21之邊緣211貫穿穿孔131甚至凸出穿孔131，進而可能造成結構相互干涉，因此電路板21之邊緣211可形成前述截角部212，使得電路板21之邊緣211不會凸出穿孔131。According to different design requirements, the LED display unit 1 will use LED display modules 20 with different LED setting spacings. As shown in FIGS. 6A to 6C , it is assumed that the LED display module 20 of the LED display unit 1 adopts LED setting pitches of 5 mm, 3 mm and 1 mm respectively, but all use the same specifications of the base 10 . When the LED spacing is set to 5mm, the edge 211 of the circuit board 21 of the LED display module 20 only needs to extend into the through hole 131 for a short distance to reach the shortest distance (about 2.5mm) between the edge LED element 22a and the symmetry plane P. ; Therefore, when the two LED display units 1 are spliced, the distance between the two adjacent edge LED elements 22a is also approximately 5mm. As the LED setting distance used becomes smaller, the edge of the circuit board 21 of the LED display module 20 211 also needs to extend relatively further into the through hole 131 in order to meet the aforementioned minimum distance requirements between the edge LED component 22a and the symmetry plane P (approximately 1.5mm and 0.5mm respectively). In order to prevent the edge 211 of the circuit board 21 from penetrating through the through hole. 131 may even protrude from the through hole 131 , which may cause interference between structures. Therefore, the edge 211 of the circuit board 21 can form the aforementioned truncated portion 212 so that the edge 211 of the circuit board 21 does not protrude from the through hole 131 .
請一併參考圖7A至圖7C有關本發明之LED顯示裝置之不同實施例之示意圖。如圖7A至圖7C所示，在以下實施例中，本發明之LED顯示裝置更可藉由兩個以上之LED顯示單元1相互拼接所構成。各LED顯示單元1之至少一鄰接側13可為複數鄰接側，以便於所需位置鄰接另一LED顯示單元1；而各LED顯示單元1以不同鄰接側13鄰接另一LED顯示單元1時，係對應不同之對稱面P，使得任二個相鄰LED顯示單元1基於對應之對稱面彼此鄰接後可獨立呈現一夾角，其中夾角至少為底座10之斜角之2倍且不小於90度。Please refer to FIGS. 7A to 7C for schematic diagrams of different embodiments of the LED display device of the present invention. As shown in FIGS. 7A to 7C , in the following embodiments, the LED display device of the present invention can be formed by splicing two or more LED display units 1 to each other. At least one adjacent side 13 of each LED display unit 1 can be a plurality of adjacent sides, so as to be adjacent to another LED display unit 1 at a desired position; and when each LED display unit 1 is adjacent to another LED display unit 1 with different adjacent sides 13, It corresponds to different symmetry planes P, so that any two adjacent LED display units 1 can independently present an included angle after being adjacent to each other based on the corresponding symmetry plane, where the included angle is at least twice the oblique angle of the base 10 and not less than 90 degrees.
隨著相鄰二個LED顯示單元1之間所呈夾角不同，本發明之LED顯示裝置300可構成如圖7A所示之外凸形式之曲面顯示裝置（即夾角小於180度）、如圖7B所示之平面顯示裝置（即夾角等於180度）或如圖7C所示之內凹形式之曲面顯示裝置（即夾角大於180度）。或者，本發明之LED顯示裝置300也可構成具有多邊形柱體、圓柱體、球體或六面體等立體結構之立體顯示裝置，但本發明不以此為限。As the angle between two adjacent LED display units 1 is different, the LED display device 300 of the present invention can form a convex curved display device as shown in Figure 7A (that is, the angle is less than 180 degrees), as shown in Figure 7B The flat display device shown (that is, the included angle is equal to 180 degrees) or the concave curved display device as shown in Figure 7C (that is, the included angle is greater than 180 degrees). Alternatively, the LED display device 300 of the present invention may also constitute a three-dimensional display device having a three-dimensional structure such as a polygonal cylinder, a cylinder, a sphere or a hexahedron, but the present invention is not limited thereto.

The plurality of LED display units 1 are arranged on the support frame 310 so that the plurality of LED display units 1 are carried and positioned by the support frame 310 to form the LED display device 300 of the present invention. The support frame 310 is made of a material that can be magnetically attracted, such as iron or other similar metal materials. Therefore, with the arrangement of at least one magnet 40 of the LED display unit 1 as shown in FIG. 1 , each LED display unit 1 can be quickly and easily fixed to the support frame 310 , thereby completing the assembly of the LED display device 300 of the present invention. Similarly, when any LED display unit 1 needs to be detached from the supporting frame 310, the relevant disassembly operation can be completed quickly and easily.
綜上所述，藉由本發明之LED顯示單元可適用於具有不同LED設定間距之LED顯示模組20，使得任意相鄰二個LED顯示單元之間不會出現間距差異，避免產生黑線或亮線等顯示缺陷。此外，本發明之LED顯示裝置藉由模組化之LED顯示單元之設計，可呈現所需之立體結構型態並提升組裝及之便利性。In summary, the LED display unit of the present invention can be applied to LED display modules 20 with different LED setting spacings, so that there will be no spacing difference between any two adjacent LED display units, and black lines or bright lines will be avoided. Lines etc. show defects. In addition, through the design of the modular LED display unit, the LED display device of the present invention can present the required three-dimensional structural form and improve the convenience of assembly.
