Further, the micro-diffusion structure 63 is a plurality of light-shielding points arranged in a distributed manner and having a reflective diffusion capability, so as to eliminate the light generated by the light-emitting unit 5 by the distance (ie, the light-emitting unit 5 is the brightest directly above, and the brightness is gradually decreased outward). Small) and the formation of uneven brightness. In more detail, the micro-diffusion structure 63 may be a black or white ink, and is formed on the light-incident surface 61 and the light-emitting surface 62 of the diffusion sheet 6 or one side thereof by printing a predetermined pattern.
除此之外，本實施例之直下式發光鍵盤更包括一反射片7，用以反射射出至按鍵1鍵帽11底面的光線，將光線重新利用以提升亮度。如圖3所示，反射片7是設置於銅蝕刻薄膜電路板4之上且位於擴散片6下方。反射片7還形成有多個穿孔71(為了圖式簡潔只示出一個)，以對應容置各個發光單元5，使光線得以通過。進一步地說，本實施例之反射片7為一完全白色化的反射片，為一以白色有機樹脂所製成單獨一片的反射片，並非如習知是以聚酯膠膜(麥拉片，Mylar)正面為黑背面印白所製成，因此本實施例之反射片7相較於習知反射片可具有更高光線反射率。 In addition, the direct-lit illuminated keyboard of the present embodiment further includes a reflective sheet 7 for reflecting light emitted to the bottom surface of the keycap 11 of the button 1, and reusing the light to enhance the brightness. As shown in FIG. 3, the reflection sheet 7 is disposed on the copper etched film board 4 and under the diffusion sheet 6. The reflection sheet 7 is also formed with a plurality of perforations 71 (only one is shown for simplicity of the drawing) to accommodate the respective illumination units 5 so that light can pass therethrough. Further, the reflective sheet 7 of the present embodiment is a completely whitened reflective sheet, which is a single sheet of reflective sheet made of white organic resin, which is not conventionally a polyester film (Mylar sheet, The front side of Mylar) is made of white on the black back side, so the reflection sheet 7 of the present embodiment can have higher light reflectance than the conventional reflection sheet.
