However, the present invention is not limited thereto, and more or less than four groups of the backlight units may be used to thereby define different numbers of illuminations for the illumination keyboard. Area 60. When the user presses the button 20, the signal contact is triggered to cause the circuit board 30 to generate the button. After the message processing unit μ reads the character corresponding to the key code, the character code is output to the The information processing system 70 can be a computer. The control unit 32 can receive the key code generated by the circuit board 3 as shown in FIG. 3, or can receive the word generated by the message processing unit 3 as shown in FIG. 4 . [0016] Next, the following is a block diagram of the first embodiment of the present invention, which includes a setting step (S11), and a plurality of pairs are respectively set in the control unit 32. The first to fourth f-light units 4〇a, 4〇b, 40c, 40d, and different illumination time; a detection step (§12), detecting the input signal conforms to a job After the condition, the control unit 32 is activated; a driving step (S13), the control unit 32 outputs a driving signal to the corresponding first to fourth backlight units 4〇a, 40b, 40c, 40d respectively during the lighting time. And causing the first to fourth illuminating regions 6 〇 a, 60 b, 6 〇 c, 610 d to generate brightness 'in a non-synchronous manner and an ending step ( S14 ), and after the detecting the input signal meets an end condition, the control unit is configured 32 stops rotating the drive signal. 100100770 Form No. A0101 Page 7 of 23 1002001391-0 201230107 [0018] In the present embodiment, 'the corresponding to the fourth to fourth backlight unit surgery, injury, 40c, 4Gd' the illumination time and the The driving signals are all four groups, including a first-lighting time, a second lighting time, a third lighting time and a fourth lighting time, and the driving signal includes a first driving signal, a second driving signal, and The third driving signal and the fourth driving signal. Wherein the illuminating time may be continuous (eg, the second illuminating time is subsequent to the first illuminating time) or the illuminating time may be separated by a non-illuminating time, and the (4) unit 32 will not output the non-illuminating time. Driving the signal, in addition, the illuminating time may also partially overlap each other (ie, the first illuminating time partially overlaps the second illuminating time). Further, in this embodiment, the operating condition may be preset to the control unit 32. The drive signal is output when the input signal corresponding to the "Fn" and "F1" to "F12" - buttons is simultaneously pressed. Further, when the setting step (sn) is performed, a plurality of driving modes may be pre-stored in the memory unit 33, and the driving mode is associated with the input S-number and includes an execution parameter. The execution parameter may be an output voltage value of the driving signal, an output sequence of the driving signal, or a period value of the lighting time. In addition, the detecting step (s 12) and the driving step (S13) may further comprise a determining step, and the control unit 32 determines the driving mode that the input signal conforms to, and in the driving step (S13) The control unit 32 will capture the driving board in the memory unit 33 and output the driving signal according to the 5 parameter, that is, the control unit 32 can determine the first to fourth backlight units 4〇a according to the parameter. The brightness of 4〇b, 40c, 40d, the order in which the first to fourth backlight units 4〇a, 4〇b, 40c, 40d generate brightness and the first to fourth backlight units 100100770 Form No. A0101 Page 8 / Total 23 pages 1002001391-0 201230107 4Qa M〇b, 40C, 40d each lighting time. In one embodiment, each 'drive mode' can correspond to a combination of one of the buttons "F1" to "F12" and the "p, fn" button, for example, when the user simultaneously presses the "Fn" and "F1" buttons. The control unit 32 will obtain one of the driving modes. When the user simultaneously presses the rFn" and "F2" buttons, the *unit 32 will take another driving mode, and so on. Each drive mode may represent a different output voltage value of the drive signal, a different output sequence, or a different period value of the illumination time. [0019] For example, when the lighting time is set in the order of: the first lighting time, the second lighting time, the lighting time, the fourth lighting time, the control unit 32 will sequentially The illuminating time outputs the driving signal to the first to fourth backlight units 40a, 40b, 4&c, 40d, so that the first to fourth illuminating regions 60a, 60b, 60c, 60d of the illuminating keyboard alternately generate brightness, that is, During the first lighting time, the control unit 32 outputs only the first driving signal to the first actuator 41a, and drives the first lighting element group 42a to make only the first illumination in the initial area 60. The area 6〇a generates a brightness, and after the first lighting time is exceeded, the control unit 32 stops outputting the first driving signal to the first driver 41a, and outputs the second driving signal. Up to the second driver 41b, the second light-emitting element group 42b' is driven to generate brightness only in the second light-emitting area 60b among the light-emitting areas 60, and the remaining first light-emitting area 60a and the third light-emitting area 6〇c and the first The four light-emitting regions 60d do not generate brightness, and then the first to fourth light-emitting regions 60a, 60b, 60c, 60d are alternately generated in this manner to generate brightness. [0020] Furthermore, in the present embodiment, the different driving signals are different. The first 100100770 form number A0101 page 9 / 23 page 1002001391-0 201230107 to the fourth light emitting element group 42a, 42b, 42c, 42d may also provide different brightness, for example, the first driving signal may be set, The voltage values of the second driving signal, the third driving signal and the fourth driving signal are increasing or decreasing, and the first to fourth lighting regions 60a, 60b, 60c, and 6Od are gradually brightened or darkened. The way is to illuminate sequentially. In other embodiments, if the first to fourth backlight units 40a, 40b, 40c, and 4d each include a plurality of light-emitting element groups respectively providing color lights of different colors, the different driving signals may determine the light emission. The color of the color of the component group, in this way, the first to fourth light-emitting regions 60a, 60b, 60c, 60d will sequentially emit light in different colors. Finally, in the stopping step, similar to the setting of the working condition, the stopping condition may be preset to, for example, when detecting that the user presses the input signal corresponding to the “Fn” and “Esc” buttons at the same time, The control unit 32 does not output a talk drive signal. [0021] Please continue to refer to FIG. 6 , which is a block diagram of a second embodiment of the present invention, including: a setting step (S21), in which the control unit 32 sets a plurality of corresponding light-emitting regions and is phased. a different illuminating time; a detecting step (S22), detecting that the input signal is not generated for more than a predetermined time to start the control unit 32; - driving step (S23), the control unit 32 respectively outputting one during the illuminating time Driving the signal to the corresponding backlight unit to cause the light emitting area to generate brightness asynchronously; and in an end step (S24), the control unit 32 stops outputting the driving signal after receiving the input signal. [0022] The second embodiment of the present invention described above The steps of the example can also be implemented by the illuminated keyboard and circuit architecture of FIG. 1 to FIG. 4, wherein when the user does not touch the button 20 after the predetermined time is idle, the control unit 32 is activated and the form number is 100100770. A0101 Page 10 of 23 1002001391-0 201230107 The driving signal is respectively output to the corresponding backlight unit during the lighting time. In addition, a driving mode may be pre-stored in the memory unit 33, and the driving mode may include at least one execution parameter, where the execution parameter may be an output voltage value of the driving signal, an output sequence of the driving signal, or a period of the lighting time. Value, etc. When the driving step (S23) is executed, the control unit 32 outputs the driving signal according to the parameter. In this embodiment, the ending step (S24) is when the user touches one of the buttons 20, and the control unit 32 stops the output of the driving signal after receiving the input signal. [0023] The method for controlling the flashing brilliance change of the illuminating keyboard is mainly that the illuminating keyboard is divided into a plurality of illuminating regions according to the backlight unit, and the driving signal is respectively output by the control unit at different illuminating times, so that the driving signal is The backlight unit generates brightness in a certain order, whereby the illuminated keyboard can exhibit a brightness performance with a flickering effect. On the other hand, by changing the brightness and color of the backlight unit, the illuminated keyboard can display a brilliant multi-color illumination effect through non-synchronized brilliance changes. Therefore, the present invention is highly progressive and conforms to the patent requirements of the application for publication, and the application is made according to law, and the praying office grants the patent as soon as possible, and it is a matter of fact.
