以下請參照圖6，圖6繪示本發明另一實施例的發光鍵盤的示意圖。發光鍵盤600包括鍵盤控制器610、按鍵陣列620以及發光元件LD1。鍵盤控制器610包括圖像解碼器611以及驅動信號產生器612。按鍵陣列620中包括多個按鍵KY1。在本實施例中，鍵盤控制器610可驅使按鍵陣列620執行掃描動作，並接收按鍵陣列620所產生的輸入資訊（例如鍵盤掃描碼）。另外，鍵盤控制器610可提供驅動信號DRVX以驅動發光元件LD1。在本實施例中，發光元件LD1可以與按鍵KY1重疊配置。且每個按鍵KY1可以與一個或多個發光元件LD1重疊配置。Please refer to FIG. 6 below. FIG. 6 is a schematic diagram of an illuminated keyboard according to another embodiment of the present invention. The light-emitting keyboard 600 includes a keyboard controller 610, a key array 620, and a light-emitting element LD1. The keyboard controller 610 includes an image decoder 611 and a driving signal generator 612. The key array 620 includes a plurality of keys KY1. In this embodiment, the keyboard controller 610 can drive the key array 620 to perform a scanning action, and receive input information (such as a keyboard scan code) generated by the key array 620. In addition, the keyboard controller 610 can provide a driving signal DRVX to drive the light-emitting element LD1. In this embodiment, the light-emitting element LD1 may be overlapped with the button KY1. And each key KY1 can be overlapped with one or more light-emitting elements LD1.

請參照圖7繪示的本發明實施例的按鍵與發光元件的配置關係。單一按鍵KY1可與一個或多個發光元件LD1~LDN對應設置。發光元件LD1~LDN可以為發光二極體。其中，在本實施方式中，發光元件LD1~LDN可分別產生不同波長的光束。透過調整提供至發光元件LD1~LDN的驅動信號，本發明實施例可以調整發光元件LD1~LDN提供的顯示燈效的顏色及/或亮度，並提供所需要的顯示燈效。Please refer to FIG. 7 which illustrates the configuration relationship between the keys and the light-emitting elements in the embodiment of the present invention. A single button KY1 can be set corresponding to one or more light-emitting elements LD1~LDN. The light emitting elements LD1 to LDN may be light emitting diodes. Among them, in this embodiment, the light-emitting elements LD1 to LDN can respectively generate light beams of different wavelengths. By adjusting the driving signals provided to the light emitting elements LD1 to LDN, the embodiment of the present invention can adjust the color and/or brightness of the display light effects provided by the light emitting elements LD1 to LDN, and provide the required display light effects.

綜上所述，本發明的發光鍵盤透過圖像解碼器以接收圖像資料，並針對圖像資料進行解碼來產生用來驅動發光元件的驅動信號。本發明的發光鍵盤不需要為了所要達成的燈光效果（燈效）而需要透過數學公式計算與利用程式實現來產生絢麗燈光效果而曠日費時，提升發光鍵盤使用上的便利性。In summary, the light-emitting keyboard of the present invention receives image data through an image decoder, and decodes the image data to generate driving signals for driving the light-emitting elements. The luminous keyboard of the present invention does not require mathematical formula calculations and program implementations to produce brilliant lighting effects for the desired lighting effects (light effects), which is time-consuming, and improves the convenience of using the luminous keyboard.
