Description
本創作係關於一種鍵盤，特別是關於一種發光的鍵盤。This creation relates to a keyboard, and more particularly to a keyboard that emits light.
就目前電腦的使用習慣而言，鍵盤為不可或缺的輸入設備之一。不論是電腦本身或是其周邊產品，皆朝著輕、薄、短、小的設計理念發展。而鍵盤亦從早期的大型架構，轉變為薄型鍵盤。另外，目前市面上亦推出發光鍵盤，一般是在鍵盤的內部設置發光源，例如發光二極體模組（Light-emitting diode, LED），並由按鍵的周緣或鍵面透射光線，以供使用者於昏暗處仍可清楚辨別各個按鍵的位置。In terms of current computer usage habits, the keyboard is one of the indispensable input devices. Whether it is the computer itself or its peripheral products, it is developing towards a light, thin, short and small design concept. The keyboard has also changed from an early large architecture to a thin keyboard. In addition, an illuminated keyboard is also currently available on the market, generally in the interior of the keyboard, such as a light-emitting diode (LED), and transmitted by the periphery or key surface of the button for use. The position of each button can still be clearly distinguished in the dark.
一般而言，發光鍵盤包括底板、薄膜電路板、按鍵及背光模組等元件。薄膜電路板、按鍵及背光模組皆設置於底板，且背光模組包括遮光層、導光層及反射層等結構，並依序組裝於底板的下方。其中，遮光層具有複數個透光部，分別對應於該些按鍵，而發光模組設置於導光層。光線由導光層導引至整個鍵盤底部，並經反射層向上反射，再透過遮光層將光線聚集於各按鍵的位置，進而於按鍵的鍵面或周緣透出光線。In general, the illuminated keyboard includes components such as a backplane, a thin film circuit board, buttons, and a backlight module. The thin film circuit board, the button and the backlight module are all disposed on the bottom plate, and the backlight module comprises a light shielding layer, a light guiding layer and a reflective layer, and is sequentially assembled under the bottom plate.

然而，習知的底板、薄膜電路板及背光模組為層疊狀的結構，並以黏合的方係相互連接。又，底板、薄膜電路板、遮光層、導光層及反射層皆為開放型式，故容易受到外界水氣的影響。舉例而言，水氣可能會造成用於黏合底板、薄膜電路板、遮光層及導光層的膠脫落，而有開膠的情形。再者，導光層更可能因水氣而有彎曲、翹曲等變形的情況，進而造成背光模組及鍵盤的使用壽命下降，實有改善之必要。However, conventional backplanes, thin film circuit boards, and backlight modules have a laminated structure and are connected to each other by a bonding system. Moreover, the bottom plate, the thin film circuit board, the light shielding layer, the light guiding layer and the reflective layer are all open type, so they are easily affected by external moisture. For example, moisture may cause the glue to be peeled off for bonding the bottom plate, the thin film circuit board, the light shielding layer, and the light guiding layer, and there is a case where the glue is opened. Furthermore, the light guiding layer is more likely to be deformed by bending or warping due to moisture, which in turn causes a decrease in the service life of the backlight module and the keyboard, which is necessary for improvement.

In other words, the light-blocking structure 421a of the present embodiment is formed by laser processing, and the light-blocking structure 421a is formed on the periphery of the light guiding layer 42a by laser ablation. The light blocking structure 421a has a function of blocking light, which can prevent the light guided by the light guiding layer 42a from leaking outward from the side.
又，本實施例之阻光結構421a為線型，且具有至少三條阻光結構421a，並依序排列於導光層42a的周緣。其中，最內側的阻光結構421a可吸收60%～70%的光線、中間的阻光結構421a則可吸收20%～30%的光線，最外側的阻光結構421a便可吸收剩餘的光線。三條線型的阻光結構421a即可有效地避免導光層42a所導引的光線向外洩漏的情形，使發光模組所發出的光線可有效的傳送至遮光層41a，以確保鍵帽31表面透光的效果，進而可清楚顯示各鍵帽31表面的各種符號或記號等標示。Moreover, the light-blocking structure 421a of the present embodiment is linear and has at least three light-blocking structures 421a arranged in sequence on the periphery of the light guiding layer 42a. The innermost light blocking structure 421a can absorb 60% to 70% of the light, the middle light blocking structure 421a can absorb 20% to 30% of the light, and the outermost light blocking structure 421a can absorb the remaining light. The three-line type light-blocking structure 421a can effectively prevent the light guided by the light-guiding layer 42a from leaking outward, so that the light emitted by the light-emitting module can be efficiently transmitted to the light-shielding layer 41a to ensure the surface of the keycap 31. The effect of light transmission can further clearly indicate various symbols or symbols on the surface of each keycap 31.
又，習知係於導光層42a的周緣塗覆吸光油墨，或是同樣以雷射加工的方式形成一條寬度較寬的帶狀阻光結構。然而，吸光油墨的阻光效果差，而以雷射加工的方形成帶狀阻光結構，會同時造成導光層42a的周緣捲曲或翹曲。本實施例係於導光42a的周緣形成至少三條線型的阻光結構421a，其阻光效果優於吸光油墨，又不會使導光層42a周緣有捲曲或翹曲的情形，優於帶狀阻光結構。Further, it is conventional to apply a light-absorbing ink to the periphery of the light guiding layer 42a, or to form a wide strip-shaped light-blocking structure by laser processing. However, the light-blocking ink has a poor light-blocking effect, and the laser-processed side forms a strip-shaped light-blocking structure, which causes the peripheral edge of the light-guiding layer 42a to curl or warp at the same time. In this embodiment, at least three linear light-blocking structures 421a are formed on the periphery of the light guide 42a, and the light-blocking effect is superior to that of the light-absorbing ink, and the peripheral edge of the light-guiding layer 42a is not curled or warped, which is superior to the strip shape. Light blocking structure.
另外，由於本實施例之導光層42a之阻光結構421a可避免光線從導光層42a的側邊洩漏，且反射層43a的內表面亦具有白色塗層431a，以反射自導光層42a所射出的光線，故反射層43a的外表面可印刷或塗覆任何顏色的塗料，而不限於深色塗料。In addition, since the light blocking structure 421a of the light guiding layer 42a of the embodiment can prevent light from leaking from the side of the light guiding layer 42a, and the inner surface of the reflective layer 43a also has a white coating 431a to reflect the self-light guiding layer 42a. The light emitted, so that the outer surface of the reflective layer 43a can be printed or coated with a coating of any color, without being limited to a dark paint.
綜上所述，依據本創作之鍵盤，薄膜電路板設置於底板的上方，背光模組包括遮光層、導光層、反射層及防水件，而遮光層、導光層、反射層依序設置於底板的下方。防水件的一側連接於反射層，另一側延伸形成一凹槽，且凹槽套設於底板、薄膜電路板、及遮光層的周緣，進而可減少水氣對於底板、薄膜電路板、遮光層及導光層的影響，以避免開膠的問題，進而可達到延長背光模組及鍵盤之使用壽命的效果。In summary, according to the keyboard of the present invention, the thin film circuit board is disposed above the bottom plate, and the backlight module comprises a light shielding layer, a light guiding layer, a reflective layer and a waterproof member, and the light shielding layer, the light guiding layer and the reflective layer are sequentially arranged. Below the bottom plate. One side of the waterproof member is connected to the reflective layer, and the other side extends to form a groove, and the groove is sleeved on the periphery of the bottom plate, the thin film circuit board, and the light shielding layer, thereby reducing moisture and moisture on the bottom plate, the thin film circuit board, and the shading The effect of the layer and the light guiding layer to avoid the problem of opening the glue, thereby achieving the effect of prolonging the service life of the backlight module and the keyboard.
