In order to make the above description of the present invention more comprehensible, a preferred embodiment will be described below in detail with reference to the accompanying drawings: FIG. 1 A schematic diagram of an electronic device of a preferred embodiment includes an display module 110 and a keyboard module 130. The keyboard module 13 is coupled to the display module 11A. The electronic device 100 herein is a notebook computer, but is not limited thereto. The electronic device 100 can also be other electronic devices having a keyboard module, such as a Digital Personal Assistant (PDA) or a mobile phone. Please refer to FIG. 2A and FIG. 2B simultaneously. FIG. 2A shows a partial schematic view of the button module in FIG. 1 , and FIG. 2B shows the keyboard module along the section line 2B-2B in FIG. 2A . Sectional view. The keyboard module 130 includes a light source group 131, a plurality of buttons 133, and a mode controller 135. The light source group 131 is disposed below the button 133 and includes two light sources 131a and 131b. The light sources 131a and 131b are used to generate color lights of different colors. The button 133 includes a color transfer layer CL', and one of the light transmissive layers s 201036020 has patterns S1 and S2. As shown in Fig. 2A, the patterns S1 and S2 are respectively illustrated by a numeral "1" and a phonetic symbol "gate". Of course, the patterns S1 and S2 can also be other letters, symbols or numbers. The pattern S1 is for converting the color of the color light generated by the light source 131a therethrough such that the color light passing through the pattern S1 and the color light passing through the region outside the pattern S1 in the light transmitting surface S are different in color. Further, the pattern S2 is for converting the color of the color light generated by the light source 131b therethrough so that the color of the color light passing through the pattern S2 and the region passing through the pattern S2 in the light transmitting surface is different. U When the mode controller 135 enables the light sources 131a and 131b according to the input modes of the electronic device 100 in FIG. 1, the patterns S1 and S2 are different from the colors of the regions other than the light transmitting surface S. Appeared. In this way, in different modes of operation, the button 133 can clearly display a pattern corresponding to the mode of operation performed to facilitate user identification and operation. Hereinafter, the color light passing through the pattern S1 is blue, and the color light in the region outside the pattern S1 in the light transmitting surface S is green. As shown in Fig. 3A, Q, when the user switches the mode in which the input mode of the electronic device 100 is the input number, the mode controller 135 enables the light source 131a so that the light source 131a generates the color light L1. The color light L1 passing through the pattern S1 is converted into blue color light B. Further, the color light L1 passing through the region outside the pattern S1 in the light transmitting surface S is converted into the green color light G. In this way, as shown in FIG. 3B, the light transmissive surface S of the button 133 clearly shows the pattern S1 by the color difference, that is, the number "1", so that the user can quickly find out for input. The button for the number "1". In addition, the color light passing through the pattern S2 is yellow, and the color of the region outside the pattern S2 in the light transmitting surface S is red as an example. As shown in Fig. 4A, assuming that the user switches the input mode of the electronic device (10) to the mode of inputting the left note, the mode controller 135 enables the light source 131b' to cause the light source 131b to generate color light. . The color of the colored light L2 is different from the color of the colored light L1. The color light L2 passing through the pattern % is converted into a yellow color light Y. Further, the color light L2 passing through the region outside the pattern % in the light transmitting surface s is converted into the red color light R. In this way, as shown in the figure, the light-transmissive surface S of the button 133 clearly shows the pattern S2 by the color difference, that is, the phonetic symbol "gate", so that the user can quickly find out Enter the button for the phonetic symbol "Door". Continuing the above example, as shown in Fig. 5, the pattern S1 and the pattern S2 are overlapped with each other in the fe circumference R1. The region outside the pattern S2 in the pattern S1 and the light transmitting surface s overlaps each other in the range R.2. The pattern S2 and the region outside the pattern S1 in the light transmitting surface s overlap each other in the range R3. The area outside the pattern S1 in the light transmitting surface s and the area outside the pattern S2 in the light transmitting surface s overlap each other in the range R4. Referring to FIGS. 3B and 4B simultaneously, in the range R1, the passed color light L1 is converted into blue color light B, and the passed color light L2 is converted into yellow color light γ. In the range R2, the passed color light L1 is converted into blue color light b, and the passed color light L2 is converted into red color light R. In the range R3, the passed color light L1 is converted into green color light G' and the passed color light L2 is converted into yellow color light Y. The color light L1 passed in the range R4 is converted into green color light G, and the passed color light L2 is converted into red color light R. Therefore, in the selection of the material, in the range R1, the material of the color light B in which the mixed color light L1 is mixed with blue, and the material in which the color light L2 is converted into yellow color 201036020 light Y are used. Similarly, the range R2, R3, and R4 are mixed with two materials to convert the colors of the color lights L1 and L2 such that the pattern S1 is different from the color of the area outside the pattern S1 in the light transmitting surface S, and the pattern S2 and the light transmitting surface s are The areas outside the pattern S2 are different in color. The above examples are all exemplified by the pattern and the area outside the pattern in the light-transmissive surface for converting the color of the color light. However, if the color of the color light passing through the pattern is different from the color of the color light generated by the original light source, the area outside the pattern in the light transmitting surface can directly pass the color light to maintain its color. For example, assuming that the color light produced by the light source is yellow and the color of the colored light passing through the pattern is blue, the area outside the pattern in the light transmissive surface allows the yellow colored light to pass in a manner to maintain its color. As a result, the color light passing through the pattern is blue, and the color light passing through the area outside the pattern in the light transmitting surface is maintained yellow. The pattern can also be clearly displayed by the difference in color for the user to recognize and operate. The keyboard module and the electronic device using the same according to the above embodiments of the present invention have a light-transmissive surface of a single button that displays a corresponding pattern according to an input mode © of the electronic device. The pattern and the area outside the pattern in the light-transmissive surface emit colored light of a different color' for the user to distinguish and operate. In view of the above, the present invention has been disclosed in a preferred embodiment, and is not intended to limit the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
