The light absorbing layer 2 is disposed on the substrate 1, and a plurality of light emitting diode units 3 are also disposed on the substrate 1. The substrate 1 of the present embodiment is an aluminum substrate, but is not limited thereto.
詳細說明之，本創作的吸光層2設置在基板1上，具體來說，本創作吸光層2分成彼此分離的第一吸光層21以及第二吸光層22。第一吸光層21與第二吸光層22分別設置在基板1的兩個相反表面上。如圖2及圖3所示，第一吸光層21設置在基板1的一表面，第二吸光層22則設置在基板1的另一相反表面。本創作的吸光層2可具有一預定圖案。預定圖案可以完全覆蓋基板的表面，也可以部分地覆蓋基板的表面。 In detail, the light absorbing layer 2 of the present invention is disposed on the substrate 1. Specifically, the present light absorbing layer 2 is divided into a first light absorbing layer 21 and a second light absorbing layer 22 which are separated from each other.

As shown in FIGS. 2 and 3, the first light absorbing layer 21 is disposed on one surface of the substrate 1, and the second light absorbing layer 22 is disposed on the other opposite surface of the substrate 1. The light absorbing layer 2 of the present invention may have a predetermined pattern. The predetermined pattern may completely cover the surface of the substrate, or may partially cover the surface of the substrate.
在本實施例中，每一個發光二極體單元3設置在基板1的上表面上，第一吸光層21則配合發光二極體單元3定位完畢後設置在基板1的上表面，第二吸光層22則相對第一吸光層21設置在基板1的下表面。 In this embodiment, each of the light emitting diode units 3 is disposed on the upper surface of the substrate 1, and the first light absorbing layer 21 is disposed on the upper surface of the substrate 1 after the positioning of the light emitting diode unit 3, and the second light absorbing. The layer 22 is disposed on the lower surface of the substrate 1 with respect to the first light absorbing layer 21.
吸光層2的預定圖案可以是條紋狀、點狀、波浪狀、不規則圖案或其組合。本實施例是以吸光層2(包括第一吸光層21以及第二吸光層22)完全覆蓋基板1的設有發光二極體單元3之外的剩餘表面作為例示，然不限於此。吸光層2可為深色的吸光塗料。 The predetermined pattern of the light absorbing layer 2 may be a stripe shape, a dot shape, a wave shape, an irregular pattern, or a combination thereof. In the present embodiment, the remaining surface of the substrate 1 except the light-emitting diode unit 3 is completely covered by the light absorbing layer 2 (including the first light absorbing layer 21 and the second light absorbing layer 22), but is not limited thereto. The light absorbing layer 2 can be a dark light absorbing coating.
承上所述，本創作的每一個發光二極體單元3沿著基板1的一邊排列設置在基板上，且每一個發光二極體單元3的發光面301是垂直於基板1，同時亦垂直吸光層2。每一個發光二極體單元3是包括多個發光二極體晶片31以及包覆多個發光二極體晶片31的封裝體32。多個發光二極體晶片31包括紅色發光二極體R、藍色發光二極體B、綠色發光二極體G或其組合，然不限於此。封裝體32的其中一側邊321與基板1的一側邊11是相互切齊或不 切齊(例如部分地超出基板1的一側邊11)。在本創作是以互相切齊的方式作為示例(如圖2)。由於發光二極體單元3的發光面301是垂直基板1，可直接朝向基板1一側邊出光。舉例來說，以圖3的前視圖作為說明，每一個發光二極體單元3是朝向紙面垂直出光，且每一個發光二極體單元3具有多個發光二極體晶片31，特別是紅色發光二極體R、綠色發光二極體G及藍色發光二極體B，以進行發光。然而，本創作不以此舉例為限。 As described above, each of the light-emitting diode units 3 of the present invention is arranged on the substrate along one side of the substrate 1, and the light-emitting surface 301 of each of the light-emitting diode units 3 is perpendicular to the substrate 1, and is also vertical.

One side edge 321 of the package body 32 and one side edge 11 of the substrate 1 are aligned with each other or not. It is cut (for example partially beyond one side 11 of the substrate 1). This creation is an example of a mutually aligned approach (Figure 2). Since the light-emitting surface 301 of the light-emitting diode unit 3 is the vertical substrate 1, light can be directly emitted toward the side of the substrate 1. For example, taking the front view of FIG. 3 as an illustration, each of the light emitting diode units 3 emits light perpendicularly toward the paper surface, and each of the light emitting diode units 3 has a plurality of light emitting diode chips 31, particularly red light. The diode R, the green light-emitting diode G, and the blue light-emitting diode B emit light. However, this creation is not limited to this example.
[第二實施例] [Second embodiment]
請參閱圖4至圖5所示，本創作第二實施例提供一種發光二極體顯示器E。圖4為側視示意圖，圖5為前視示意圖。本實施例的發光二極體顯示器E是由多個前述的顯示模組D相互配合而組成。如圖4所示，多個顯示模組D以層疊方式垂直地排列。顯示模組D包括基板1、第一吸光層21、第二吸光層22以及多個發光二極體單元3。本實施例中與第一實施例相同的元件請參閱前述，不再於此贅述。在發光二極體顯示器E中，由於多個顯示模組D以堆疊方式排列，且多個顯示模組D設置在一顯示屏幕S的一側，顯示屏幕S可為透明屏幕。如圖5所示，以前視角度觀看，當顯示模組D的多個發光二極體單元3發光時，多個光線朝向顯示屏幕S的方向出光(朝向紙面的方向)，如此可形成影像投在顯示屏幕S上。 Referring to FIG. 4 to FIG. 5, a second embodiment of the present invention provides a light emitting diode display E. 4 is a side view, and FIG. 5 is a front view. The LED display E of the present embodiment is composed of a plurality of the aforementioned display modules D. As shown in FIG. 4, a plurality of display modules D are vertically arranged in a stacked manner. The display module D includes a substrate 1, a first light absorbing layer 21, a second light absorbing layer 22, and a plurality of light emitting diode units 3. For the components in this embodiment that are identical to the first embodiment, refer to the foregoing, and no further details are provided herein. In the light-emitting diode display E, since the plurality of display modules D are arranged in a stacked manner, and the plurality of display modules D are disposed on one side of the display screen S, the display screen S may be a transparent screen. As shown in FIG. 5, when the plurality of light emitting diode units 3 of the display module D emit light, the plurality of light rays emit light toward the display screen S (direction toward the paper surface), so that the image projection can be formed. On the display screen S.
本實施例以三個顯示模組D作為例示，為了便於說明，在本實施例中定義第一顯示模組D1、第二顯示模組D2以及第三顯示模組D3，然本創作不以此為限。根據圖4，第二顯示模組D的發光面301射出的出射光L射向顯示屏幕S，部分的光會被顯示屏幕S反射成為第一反射光R1。第一反射光R1被設置在上方的第一顯示模組D1的基板1下表面的第二吸光層21部分吸收，且部分反射成為第二反射光R2。第二反射光R2朝向第二顯示模組D2 發光，且被基板1上表面的第一吸光層21部分吸收，部分反射成為第三反射光R3。第三反射光R3朝向發光二極體顯示器E的後方射出。由於從發光面301射出的出射光L的反射光經過上下顯示模組的第一吸光層21與第二吸光層22的吸收之後，光的強度逐漸減弱，L>R1>R2>R3。除了直接從顯示屏幕S反射的光之外，本創作的顯示模組D的吸光層2也可吸收來自鄰近顯示模組D的發光二極體晶片單元3的發光面301所發散的餘光。藉此，透過多個顯示模組D垂直堆疊且發光面301垂直基板1的設置方式，加上每個基板1的兩相反表面均設有吸光層2，可以有效地吸收經各元件表面反射的光，如此可避免在每一個顯示模組D之間因反射光的炫光現象所造成的低對比度，同時可避免屏幕產生殘影。 In this embodiment, three display modules D are taken as an example. For convenience of description, the first display module D1, the second display module D2, and the third display module D3 are defined in this embodiment. Limited. According to FIG. 4, the emitted light L emitted from the light-emitting surface 301 of the second display module D is incident on the display screen S, and part of the light is reflected by the display screen S into the first reflected light R1. The first reflected light R1 is partially absorbed by the second light absorbing layer 21 disposed on the lower surface of the substrate 1 of the first display module D1 above, and partially reflected as the second reflected light R2. The second reflected light R2 faces the second display module D2 It emits light and is partially absorbed by the first light absorption layer 21 on the upper surface of the substrate 1, and partially reflected into the third reflected light R3. The third reflected light R3 is emitted toward the rear of the light-emitting diode display E. Since the reflected light of the emitted light L emitted from the light-emitting surface 301 is absorbed by the first light-absorbing layer 21 and the second light-absorbing layer 22 of the upper and lower display modules, the intensity of the light is gradually weakened, and L>R1>R2>R3. In addition to the light reflected directly from the display screen S, the light absorbing layer 2 of the display module D of the present invention can also absorb the residual light emitted from the light emitting surface 301 of the light emitting diode chip unit 3 adjacent to the display module D. Thereby, through the manner in which the plurality of display modules D are vertically stacked and the light-emitting surface 301 is perpendicular to the substrate 1, and the opposite surfaces of each of the substrates 1 are provided with the light-absorbing layer 2, the surface reflection of each element can be effectively absorbed. The light can avoid the low contrast caused by the glare of the reflected light between each display module D, and at the same time avoid the afterimage of the screen.
