Description
本創作係提供一種應用於鍵盤背光模組之軟性電路板，尤指可將軟性電路板二次反折疊合後使複數發光二極體形成二相鄰並排結構設計，可提昇發光二極體空間設計上之彈性，也可有效節省軟性電路板使用面積使生產成本更為低廉。The present invention provides a flexible circuit board applied to a keyboard backlight module, in particular, a flexible circuit board can be folded back twice to form a plurality of adjacent light-emitting diodes to form two adjacent side-by-side structure designs, thereby improving the space of the light-emitting diode. The flexibility of design can also effectively save the use area of flexible circuit boards and make the production cost lower.
按，現今電子科技與資訊產業的快速發展，使各種電子產品皆朝向輕、薄、短、小且功能強大的趨勢發展，如電腦、筆記型電腦、行動上網裝置(MID)、智慧型手機、平板電腦等，已成為現代人在日常生活或工作上所不可或缺的電子產品，而使用者與電子產品之間大多是使用滑鼠、鍵盤等輸入裝置來溝通，其中又以鍵盤最為方便作文字、數字或指令的輸入操作，並提昇實用的功能。According to the rapid development of today's electronic technology and information industry, various electronic products are moving toward light, thin, short, small and powerful trends, such as computers, notebook computers, mobile Internet devices (MIDs), smart phones, Tablet PCs, etc., have become indispensable electronic products for modern people in daily life or work, and most of the users and electronic products use mouse, keyboard and other input devices to communicate, and the keyboard is most convenient. Input operations for text, numbers, or commands, and enhance useful functions.
再者，為了在光線不足的環境下能使人眼清楚的看到每個按鍵上的符號，便有業者在鍵盤中導入導光板及光源技術，並發展出具背光模組之背光鍵盤，使背光模組所產生之光線可投射到每個鍵帽的背面處形成背光效果，讓使用者可以清楚看到鍵帽上的符號，以方便操作使用，而目前市面上之背光鍵盤包括有按鍵模組及背光模組，其中該背光模組為具有一導光板，並於導光板一側表面處設有具軟性電路板及至少一個發光 二極體之發光單元，且發光單元為朝導光板投射光線使導光板均勻發光，另於導光板下方處為設有可將導光板下表面所射出的光線反射回導光板上之反光片，並於導光板上表面設有對應於按鍵模組處之遮光片，且遮光片上具有至少一個可供光線穿過之透光部，便可將導光板所射出的光線穿過遮光片之透光部入射至按鍵模組上形成背光，但因傳統背光模組之發光單元採用的配置方式，係將軟性電路板設置於背光鍵盤長邊方向的位置上，此種配置方式將會使軟性電路板所需的面積較大，且因軟性電路板亦並非設置在背光鍵盤的中央位置，便會造成背光鍵盤整體所需之發光二極體數量亦較多，進而導致使背光鍵盤的生產成本相對提高，並連帶影響到背光鍵盤在市場上之競爭力。Furthermore, in order to enable the human eye to clearly see the symbols on each button in a low-light environment, a manufacturer introduces a light guide plate and a light source technology into the keyboard, and develops a backlit keyboard with a backlight module to make the backlight The light generated by the module can be projected onto the back of each keycap to form a backlight effect, so that the user can clearly see the symbol on the keycap for convenient operation, and the backlight keyboard currently on the market includes a button module. And a backlight module, wherein the backlight module has a light guide plate, and has a flexible circuit board and at least one light emitting on one side surface of the light guide plate The light-emitting unit of the diode, wherein the light-emitting unit projects light to the light guide plate to uniformly emit light, and the reflector below the light guide plate is provided with a reflector capable of reflecting the light emitted from the lower surface of the light guide plate back to the light guide plate. And a light shielding sheet corresponding to the button module is disposed on the surface of the light guide plate, and the light shielding sheet has at least one light transmitting portion through which the light passes, so that the light emitted by the light guiding plate can pass through the light shielding sheet. The part is incident on the button module to form a backlight. However, due to the arrangement of the light-emitting unit of the conventional backlight module, the flexible circuit board is disposed at the position of the long side of the backlight keyboard. This configuration mode will enable the flexible circuit board. The required area is large, and since the flexible circuit board is not disposed at the center of the backlit keyboard, the number of light-emitting diodes required for the backlight keyboard as a whole is also large, which leads to a relatively high production cost of the backlit keyboard. And related to the impact of the backlit keyboard in the market.
而為了改善上述之背光模組因配置方式所造成背光鍵盤成本提高之問題，便有業者將軟性電路板設置在背光鍵盤的基板中央位置，並與短邊形成平行，使軟性電路板所需之面積及發光二極體之數量減少以降低生產成本，請參閱第八圖所示，係為習用軟性電路板之俯視圖，由圖中可清楚看出，其中該軟性電路板A上為設有複數發光二極體A1，並由軟性電路板A一側處設有具複數接點A21之電源連接部A2，由於目前背光鍵盤設計愈來愈趨向於小型化，使背光鍵盤內部之空間亦趨於窄小，此種複數發光二極體A1為耦接於軟性電路板A上並根據不同的發光方向形成交錯排列，便會造成各二相鄰直線並排之複數發光二極體A1之間形成有一間距D，不僅將浪費軟性電路板A上之使用面積而無法更加有效的降低成本，並會影響到背光鍵盤內部之整體空間配置，以致使背光鍵盤之其它構件皆需配合予以改變，而無法充分應用背光鍵盤內部有限的空間， 導致成本及空間配置上之彈性便會受到侷限，即為從事此行業者所亟欲研究改善之關鍵所在。In order to improve the problem of the backlight keyboard being improved due to the configuration mode of the backlight module described above, a manufacturer places the flexible circuit board at the center of the substrate of the backlit keyboard, and forms a parallel with the short side to make the flexible circuit board required. The area and the number of light-emitting diodes are reduced to reduce the production cost. Please refer to the top view of the conventional flexible circuit board as shown in the eighth figure. It can be clearly seen from the figure that the flexible circuit board A is provided with a plurality of The light-emitting diode A1 is provided with a power connection portion A2 having a plurality of contacts A21 on one side of the flexible circuit board A. Since the current backlight keyboard design is increasingly miniaturized, the space inside the backlit keyboard tends to be smaller. The plurality of light-emitting diodes A1 are coupled to the flexible circuit board A and are staggered according to different light-emitting directions, so that a plurality of light-emitting diodes A1 are formed between the two adjacent straight lines. The spacing D not only wastes the use area on the flexible circuit board A, but also can not reduce the cost more effectively, and affects the overall space configuration inside the backlit keyboard, so that the backlit keyboard The other components need to be changed to match, and the limited space inside the backlit keyboard cannot be fully applied. The flexibility in cost and space allocation will be limited, which is the key to research and improvement for those in this industry.

本創作軟性電路板12之電源連接部122為電性連接於背光鍵盤內部電路模組(圖中未示出)之電連接器內，以提供複數發光二極體121所需之電力，當發光二極體121發光時，可朝導光板11投射光線使光線可在導光板11中進行傳遞均勻的發光，由於反光片13並不會透光，便可利用反光片13將導光板11下表面所射出的光線反射回導光板11上，並使光線僅能夠通過遮光片14上之複數透光部141，再入射至按鍵模組2上具有可透光性之按鍵單元22處穿出後，即可達到良好的背光鍵盤發光之效果，以此軟性電路板12二次反折疊合後使複數發光二極體121可形成二相鄰並排而不同的發光方向排列之結構設計，可提昇發光二極體121空間設計之彈性，亦不會影響到背光鍵盤內部其它構件之空間配置，以充分應用背光鍵盤內部可供利用的有限空間，也可有效節省軟性電路板12之使用面積使整體生產成本更為低廉，兼具有空間設計之彈性與降低成本之效用。The power connection portion 122 of the flexible circuit board 12 is electrically connected to the electrical connector of the internal circuit module (not shown) of the backlight keyboard to provide the power required for the plurality of LEDs 121. When the diode 121 emits light, the light can be projected toward the light guide plate 11 so that the light can be uniformly transmitted in the light guide plate 11. Since the retroreflective sheet 13 does not transmit light, the reflective sheet 13 can be used to lower the lower surface of the light guide plate 11. The emitted light is reflected back on the light guide plate 11, and the light can pass through only the plurality of transparent portions 141 on the light shielding sheet 14, and then enters the button unit 22 of the button module 2 with the light transmissive button unit. The effect of the good backlight keyboard illumination can be achieved, so that the flexible circuit board 12 can be folded back twice, so that the plurality of light-emitting diodes 121 can form two adjacent side-by-side and different light-emitting directions, which can enhance the light-emitting structure. The flexibility of the space design of the polar body 121 does not affect the spatial configuration of other components inside the backlit keyboard, so as to fully utilize the limited space available inside the backlit keyboard, and also effectively save the use area of the flexible circuit board 12. The overall production cost is lower, and it has the flexibility of space design and the effect of reducing costs.
上述詳細說明為針對本創作一種較佳之可行實施例說明而已，惟該實施例並非用以限定本創作之申請專利範圍，凡其它未脫離本創作所揭示之技藝精神下所完成之均等變化與修飾變更，均應包含於本創作所涵蓋之專利範圍中。The above detailed description is intended to illustrate a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and other equivalents and modifications may be made without departing from the spirit of the invention.
