The shielding layer, the reflective sheet and the light shielding member define a sealed space for the light guide plate, and the light shielding plate is closed by the sealed space, thereby reducing the overall light leakage phenomenon and further improving the brightness.
過去習知的發光鍵盤多為採行降低漏光的方式以提升鍵盤整體的亮度,然而,卻忽略了角落或邊緣的字 鍵因與光源距離遠,而有局部亮度不足的缺點。In the past, the conventional illuminated keyboards mostly used the method of reducing light leakage to improve the brightness of the keyboard as a whole, but ignored the words at the corners or edges. The key has a short distance from the light source and has the disadvantage of insufficient local brightness.
因此,本新型之目的,即在提供一種將導光板部份漏光並提升特定區域亮度的背光模組。Therefore, the purpose of the present invention is to provide a backlight module that leaks light from a portion of the light guide plate and enhances brightness of a specific region.

該導光板包括相反的一頂面及一底面,及一連接該頂面及該底面周邊的周面。The light guide plate includes an opposite top surface and a bottom surface, and a peripheral surface connecting the top surface and the periphery of the bottom surface.
該發光單元裝設在該導光板,用以提供光源。The light emitting unit is mounted on the light guide plate to provide a light source.
該遮光片裝設在該導光板的頂面,並包括至少一形成於周緣的截除區,該截除區讓該導光板部分漏光。The light shielding sheet is disposed on the top surface of the light guide plate, and includes at least one cutting portion formed on the periphery, the cutting portion partially leaking the light guide plate.
該膠層採用吸光材質,並包圍設置在該導光板的周面,且部分延伸至該底面。The adhesive layer is made of a light absorbing material and surrounds the peripheral surface of the light guide plate and partially extends to the bottom surface.
該反射片藉該膠層而連接該導光板的底面。The reflective sheet is connected to the bottom surface of the light guide plate by the adhesive layer.
本新型之另一目的,即在提供一種使用前述背光模組的發光鍵盤。Another object of the present invention is to provide an illuminated keyboard using the aforementioned backlight module.
於是本新型發光鍵盤,包含一如前述之背光模組,及一鍵盤單元。Therefore, the novel illuminated keyboard comprises a backlight module as described above and a keyboard unit.
該背光模組的該遮光片還包括複數能供光穿透的透光區。The light shielding sheet of the backlight module further includes a plurality of light transmitting regions for light to penetrate.
該鍵盤單元裝設在該背光模組的遮光片,並包括複數鍵帽。該等鍵帽分別對應該等透光區及該截除區設置,並具有至少一能供光穿透的穿透區。The keyboard unit is mounted on the light shielding sheet of the backlight module and includes a plurality of key caps.

在本新型被詳細描述之前,應當注意在以下的說明內容中,類似的元件是以相同的編號來表示。Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.
參閱圖1、圖2及圖3,本新型發光鍵盤之第一實施例包含一背光模組2、一鍵盤單元3,及一外殼4。Referring to FIG. 1 , FIG. 2 and FIG. 3 , the first embodiment of the novel illuminated keyboard comprises a backlight module 2 , a keyboard unit 3 , and a casing 4 .
該背光模組2包括一導光板21、一發光單元22、一黏接層24、一遮光片23、一膠層25,及一反射片26。The backlight module 2 includes a light guide plate 21 , a light emitting unit 22 , an adhesive layer 24 , a light shielding sheet 23 , a glue layer 25 , and a reflection sheet 26 .
該導光板21具有相反的一頂面211及一底面212,及一連接該頂面211及該底面212周邊的周面213。The light guide plate 21 has an opposite top surface 211 and a bottom surface 212, and a peripheral surface 213 connecting the top surface 211 and the bottom surface 212.
該發光單元22裝設在該導光板21,用以提供光源,並具有至少一發光二極體221(LED)。在本實施例中,該發光二極體221為七個,且嵌設在該導光板21的中央部分,並沿著該導光板21的一中線L1附近相間隔地設置。The light emitting unit 22 is disposed on the light guide plate 21 for providing a light source and has at least one light emitting diode 221 (LED). In the present embodiment, the light-emitting diodes 221 are seven and are embedded in the central portion of the light guide plate 21 and are spaced apart along the vicinity of a center line L1 of the light guide plate 21.
該遮光片23裝設在該導光板21的頂面211,並具有複數能供光穿透的透光區231,及至少一形成於周緣的截除區232。該遮光片23的製作,是能採用一透明的片材上以油墨印刷遮蓋不欲透光之處,再於周緣截除不需要之部分,其中,未印刷油墨之處即為該等透光區231,而周緣截除之處即為該截除區232。The light shielding sheet 23 is disposed on the top surface 211 of the light guide plate 21, and has a plurality of transparent regions 231 for light to pass through, and at least one cutting portion 232 formed on the periphery. The light shielding sheet 23 can be formed by using a transparent sheet to cover the undesired light by ink printing, and then cutting off the unnecessary portion at the periphery, wherein the ink is not printed. Zone 231, and the cut-off zone 232 is where the perimeter is cut.
參閱圖2、圖4及圖5,該截除區232使該遮光片23的周緣與該導光板21的周緣不重疊,因此能使該導光板21部分漏光。在本實施例中,該遮光片23具有四截除區232,分別將該遮光片23的四個角截除。將角落截除的原因在於本實施例中該發光單元22是嵌設在該導光板21的中央,因此,角落處較為遠離光源,導致光強度較低。在截除該遮光片23的四個角後,能使該導光板21的角落產生部分漏光的現象(如圖4所示之一光線方向I),藉此提高光通量,增加亮度。Referring to FIGS. 2, 4, and 5, the cut-out region 232 does not overlap the periphery of the light-shielding sheet 23 and the periphery of the light guide plate 21, so that the light guide plate 21 can partially leak light. In the present embodiment, the light shielding sheet 23 has four cut-out regions 232, which respectively cut off the four corners of the light shielding sheet 23. The reason why the corner is cut off is that the light-emitting unit 22 is embedded in the center of the light guide plate 21 in this embodiment. Therefore, the corners are farther away from the light source, resulting in lower light intensity. After the four corners of the light shielding sheet 23 are cut off, a phenomenon of partial light leakage (such as one light direction I shown in FIG. 4) can be generated in the corners of the light guide plate 21, thereby increasing the luminous flux and increasing the brightness.
值得一提的是,該截除區232的配置能對應該發光單元22的設置而改變,若該發光單元22只具有一個設置在該導光板21一角落的發光二極體221(亦即,為點光 源),則該截除區232將截除相對於該角落的另外三個角。若該發光單元22具有多數個形成於該導光板21一側的發光二極體221,則該截除區232將截除相對於該發光單元22一側的另外二個角。It is to be noted that the configuration of the cut-off area 232 can be changed corresponding to the setting of the light-emitting unit 22, if the light-emitting unit 22 has only one light-emitting diode 221 disposed at a corner of the light guide plate 21 (ie, For spot light Source), then the truncation zone 232 will intercept the other three corners relative to the corner. If the light-emitting unit 22 has a plurality of light-emitting diodes 221 formed on one side of the light guide plate 21, the cut-off area 232 will cut off the other two corners with respect to the side of the light-emitting unit 22.
前述截除區232之配置方式是為了在該導光板21光線強度較弱之處產生部分漏光,光線不被該遮光片23吸收,藉此提高光通量並增加亮度。因此,前述該截除區232配置的方式可以任意為之,而不應以本新型所公開者為限制。The cutting portion 232 is disposed in such a manner as to partially leak light when the light intensity of the light guide plate 21 is weak, and the light is not absorbed by the light shielding sheet 23, thereby increasing the luminous flux and increasing the brightness. Therefore, the manner in which the foregoing cut-off area 232 is configured may be arbitrarily determined, and is not limited by the disclosure of the present invention.

經由以上說明,可將本新型之優點歸納如下:Through the above description, the advantages of the new model can be summarized as follows:
一、藉由在該遮光片23上對應該導光板21光線較弱之處形成該截除區232,使該導光板21部分漏光,光線不被該遮光片23吸收,因而提高該導光板21周緣光線較弱之處的光通量,使該鍵盤單元3的特定區域有良好的發光效果,例如使用者常用的Esc及Ctrl等字鍵。1. The cut-off region 232 is formed on the light-shielding sheet 23 corresponding to the weak light of the light guide plate 21, so that the light guide plate 21 partially leaks light, and the light is not absorbed by the light-shielding sheet 23, thereby improving the light guide plate 21. The luminous flux at the weaker peripheral light makes the specific area of the keyboard unit 3 have a good luminous effect, such as the word keys such as Esc and Ctrl which are commonly used by the user.
二、該反射片26能使光線反射回該導光板21,提高光利用效率,並且,位於該導光板21側面的該膠體25能吸收直線光線,以避免側面漏光。2. The reflective sheet 26 can reflect light back to the light guide plate 21 to improve light utilization efficiency, and the colloid 25 located on the side of the light guide plate 21 can absorb linear light to avoid side leakage.
三、該黏接層24能採用吸光之材質,可將該導光板21邊緣的折射光吸收,使該鍵盤單元3整體之發光更為均勻。3. The adhesive layer 24 can adopt a material that absorbs light, and can absorb the refracted light at the edge of the light guide plate 21, so that the overall illumination of the keyboard unit 3 is more uniform.
參閱圖6,本新型發光鍵盤之第二實施例大致上與該第一實施例相同,差異只在於該遮光片23的截除區232是使該遮光片23的周緣形成缺口。Referring to FIG. 6, the second embodiment of the present illuminated keyboard is substantially the same as the first embodiment except that the cut-out area 232 of the light-shielding sheet 23 is such that the periphery of the light-shielding sheet 23 is notched.
該截除區232能夠任意地形成在該遮光片23周緣,因此,能選擇鄰近該基板31周緣的特定鍵帽32下方形成該截除區232,藉此提升該鍵帽32的亮度,令使用者更能準確地找到該鍵帽32。譬如,在Shift鍵下方形成該截除區232,亦或在方向鍵(圖未示)、F1鍵至F12鍵(圖未示)下方對應形成該等截除區232。The cut-out region 232 can be arbitrarily formed on the periphery of the light shielding sheet 23, and therefore, the cut-out region 232 can be formed under the specific key cap 32 adjacent to the periphery of the substrate 31, thereby enhancing the brightness of the key cap 32, so that the use The keycap 32 can be found more accurately. For example, the cut-off area 232 is formed under the Shift key, or the cut-off area 232 is formed under the direction keys (not shown) and the F1 key to the F12 key (not shown).
如此,該第二實施例不只能完成前述第一實施例之功效外,還提供另一種該截除區232的配置方式,藉此,可以提升特定鍵帽32的亮度,提升辨認的方便性。As such, the second embodiment not only performs the functions of the foregoing first embodiment, but also provides another configuration of the cutting area 232, whereby the brightness of the specific keycap 32 can be improved, and the convenience of recognition can be improved.
綜上所述,藉由在該遮光片23上形成該截除區232,使該導光板21部分漏光,增加該導光板21光線較弱之處的光通量,提升特定區域的發光效果,故確實能達成本新型之目的。As described above, by forming the cut-off region 232 on the light-shielding sheet 23, the light guide plate 21 is partially leaked, and the light flux of the light guide plate 21 is increased, thereby improving the light-emitting effect of the specific region. Can achieve the purpose of this new type.
惟以上所述者,只為本新型之實施例而已,當不能以此限定本新型實施之範圍,即大凡依本新型申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾,皆仍屬本新型專利涵蓋之範圍內。However, the above is only the embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent changes and modifications made by the scope of the patent application and the contents of the patent specification are still It is within the scope of this new patent.
