[0003] However, in addition to providing illumination, there is also an illuminated keyboard with a brilliance change effect, such as the Republic of China new patent No. M256532, which discloses a colorful illuminated keyboard, including a plurality of buttons and a colorful cold plate, the colorful The cold light plate has a plurality of light emitting regions, and the light emitting regions can respectively generate color lights of different colors. In addition, the light emitting regions can correspond to different key groups of the keyboard (eg, plural function keys, plural number keys, direction keys, etc.) 'This allows different types of button sets to have different backlight colors for the user to distinguish.
另如中華民國新型專利第M256976號，揭示—種多色發 光的鍵盤，包括一鍵盤本體、一多色區塊發光的冷光片 與一電路元件’該鍵盤本體包含一上蓋、一彈性觸動層 、一軟性電路板、複數按鍵與一底板，該按鍵排列於上 蓋的預設位置且為可透光構造。該冷光片設於該彈性觸 動層及該電路板之間，該電路板連接於該冷光片的—接 100105197 表單編號A0101 第3頁/共16頁 1002008928-0 201235885 電出端部，以供應該冷光片所需的工作電源，其中，該 冷光片包括多個區塊色層，且可發射不同顏色的光線。 [0005] 上述先前技術均是將鍵盤區分為多個可發光的區域，因 此若多個發光區域要具備有可變化的發光顏色、獨立的 發光時間、獨立的觸發訊號，則鍵盤本身需具有支援光 源驅動的控制電路。 [0006] 習知的多功能鍵盤如中華民國專利第468838號「多媒體 電腦鍵盤」，該先前案件揭示了由一鍵盤、控制鍵模組 以及模組切換鍵所構成的多功能鍵盤。其中該鍵盤内部 包含一微處理器，該微處理器支援8x18的掃瞄陣列，換 言之，該微處理器至少有26支以上的輸入接腳以支援8x 18的掃描陣列。然而，除了對應各鍵盤按鍵的掃瞄陣列 以外，該微處理器還包含了輸出、接收電力、接地等等 其他接腳。因此，用於鍵盤上的微處理器擴充的彈性取 決於該微處理器本身的接腳數量以及微處理器本身内部 的電路密度（容量）。 [0007] 為了要配合前述發光鍵盤多個發光區域的控制功能，習 知鍵盤的微處理器接腳數量以及電路容量已不敷使用， 造成多個發光區域的發光模式過少，較為呆板。若需要 讓多個發光區域具有更多樣化的發光模式，或者支援更 多發光區域，則需突破習知鍵盤微處理器擴充性不足的 問題。 【發明内容】 [0008] 由於習知發光鍵盤中的微處理器受限於體積、接腳數量 以及成本，造成該微處理器可驅動的發光元件組數量或 100105197 表單編號A0101 第4頁/共16頁 201235885 者驅動模式數量不足，㈣的f知鍵財的微處理器已 不敷使用。因此，本_目的在於提供—種發光鍵盤的 結構:令該發紐細部具有足夠的控制電路驅動多個 發光元件組，並同時可提供較多控制模式㈣該些發光 [0009]In addition, as disclosed in the Republic of China, the new patent No. M256976, a multi-color illuminated keyboard includes a keyboard body, a multi-color block light-emitting cold light sheet and a circuit component. The keyboard body includes an upper cover and an elastic touch layer. A flexible circuit board, a plurality of buttons and a bottom plate are arranged in a preset position of the upper cover and are permeable to light. The cold light sheet is disposed between the elastic touch layer and the circuit board, and the circuit board is connected to the cold light sheet - 100105197 Form No. A0101 Page 3 / Total 16 pages 1002008928-0 201235885 Electric output end to supply the The working power supply required for the cold light sheet, wherein the cold light sheet comprises a plurality of block color layers and can emit light of different colors. [0005] The foregoing prior art all divides the keyboard into a plurality of illuminable regions. Therefore, if the plurality of illuminating regions are to have a variable illuminating color, an independent illuminating time, and an independent trigger signal, the keyboard itself needs to have support. Light source driven control circuit. [0006] A conventional multi-function keyboard, such as the "Multimedia Computer Keyboard" of the Republic of China Patent No. 468838, discloses a multi-function keyboard composed of a keyboard, a control key module, and a module switching key. The keyboard internally includes a microprocessor that supports an 8x18 scan array. In other words, the microprocessor has at least 26 input pins to support an 8x18 scan array. However, in addition to the scan array corresponding to each keyboard button, the microprocessor also includes other pins for output, receive power, ground, and the like. Therefore, the flexibility of the microprocessor expansion for the keyboard depends on the number of pins of the microprocessor itself and the circuit density (capacity) inside the microprocessor itself. [0007] In order to cooperate with the control functions of the plurality of light-emitting areas of the foregoing illuminated keyboard, the number of microprocessor pins of the conventional keyboard and the circuit capacity are insufficient, and the light-emitting modes of the plurality of light-emitting areas are too small and relatively rigid. If you need to have more illuminating modes in multiple illuminating areas, or to support more illuminating areas, you need to break through the problem of insufficient expansion of the conventional keyboard microprocessor. SUMMARY OF THE INVENTION [0008] Since the microprocessor in the conventional illuminated keyboard is limited by the volume, the number of pins and the cost, the number of light-emitting component groups that the microprocessor can drive or 100105197 Form No. A0101 Page 4 / Total 16 pages 201235885 The number of driver modes is insufficient, and the microprocessor of (4) is not enough. Therefore, the purpose of the present invention is to provide a structure for an illuminated keyboard: having a plurality of control circuits for driving the plurality of light-emitting element groups, and at the same time providing more control modes (4) the illuminations [0009]
