Keyboard control method for generating brilliance change and illuminated keyboard for implementing the method

A keyboard control method for generating a brilliance change and an illuminated keyboard for implementing the method, in particular, a keyboard control method for determining a push button to drive a backlight device to provide a corresponding light color, and an illuminated keyboard for implementing the method.

When the computer has been developed, the keyboard is the necessary basic output equipment. While the personal computer is developing very fast, the keyboard still maintains the basic aspect. However, in order to facilitate the use in dimly lit environments, or in order to provide a special dazzling brilliance effect, the R&D has long installed the illuminating device in the keyboard, so that the keyboard body can emit light, which is more dazzling than the use in the dark. The appearance of the various illuminated keyboards is also widely known and widely sold in the market. In order to generate light in a small space, most of the illuminated keyboards use a light-emitting diode as a light source, and the simplest illuminated keyboard is the "lighting keyboard" of the Republic of China Patent Publication No. 509955, wherein the creation reveals a keyboard portion. And a keyboard of the backlight device, wherein the backlight device is disposed under the keyboard portion to provide light from the lower portion of the keyboard portion, and the light source may be a light emitting diode or an electroluminescent sheet. In addition to setting the light-emitting elements under the button, there is also a side light source disposed in the keyboard, and the light guide plate is used to make the light evenly emitted from the bottom of the button. For example, the Republic of China Patent Certificate No. M330513 "Keyboard Light-emitting Structure", The light-emitting element is disposed on the light-incident side of the light-guiding plate, and the light-guiding plate is disposed on the light-incident side of the light-guiding plate, and the plurality of light-guiding plates are disposed on the light-incident side of the light-guiding plate. A reflective sheet is disposed below or a reflective structure is disposed on the bottom surface to reflect the light provided by the light emitting element to the button group. The prior patents of more illuminated keyboards have the function of providing the backlight of the keyboard and being light-emitting, so that the keyboard can be used in a dimly lit place or give the user a dazzling use experience.

However, in order to change the light provided by the illuminated keyboard, the Republic of China Patent Certificate No. M256532 "Colorful Illuminated Keyboard", the prior patent discloses that a plurality of colorful cold light plates having a plurality of light emitting regions are disposed under the plurality of keys, the colorful cold light plate The plurality of light-emitting areas provide color lights of different colors, and correspond to different key groups of the keyboard (such as plural function keys, plural number keys, direction keys, etc.), so that different types of button groups have different backlight colors for distinction. However, during the production, the plurality of buttons included in the light-emitting area and the light-emitting color of the light-emitting area are preset in the production process, and the user cannot separately define the range of the light-emitting area, and the light-emitting color of the light-emitting area cannot be changed.

In summary, although the illuminated keyboard has been developed to a great extent, the light changes provided by the illuminated keyboard are still preset by the manufacturer, and the illumination mode provided is too rigid, and there is still room for further improvement.

Because the illumination color of the illuminated keyboard in the above prior art cannot be adjusted or is too monotonous to meet the preferences of some users, the purpose of the present invention is to provide a backlight unit control method and architecture for the keyboard, so that the keyboard provides a variable backlight. Color changes.

The present invention is a keyboard control method for generating brilliance changes and an illuminated keyboard for implementing the method, wherein the control method further includes at least two control steps. For example, the first step is to store a plurality of signals by constructing a driving signal table. The backlight drives the signal, and sets each backlight driving signal to correspond to at least one keying signal, and then determines that the keyboard is pressed by the input signal generated by the user to determine the output of the backlight driving signal for driving the backlight unit. Therefore, it is only necessary to additionally install a driving signal table including a plurality of backlight driving signals, and output a corresponding backlight driving signal by detecting the input signal, thereby driving the backlight unit of the pressed keyboard to emit corresponding light.

Another step is to store a plurality of backlight driving signals by setting a driving signal table, and setting each backlight driving signal to detect the input signal generation as an output condition, and detecting that the keyboard is pressed by the user to generate a keying signal. The sequence outputs a plurality of backlight driving signals. The difference between the two control steps is that after the plurality of backlight driving signals are set in the steps described in this paragraph, the backlight driving signal is sequentially outputted by the triggering of the input signal, that is, the backlight driving signal is changed according to a predefined Drive signal table. By the wheel sequence output of the backlight driving signal, a variety of brilliance changes can also be generated by the user pressing the button.

The keyboard for implementing the above method comprises a circuit board mounted in a casing, a button group for triggering the circuit board to generate a key input signal, and a backlight unit disposed under the button group, and the backlight The unit includes a plurality of light-emitting element groups that are distinguished by distinct illumination colors. The keyboard further includes a memory unit that stores a drive signal table, and a micro control unit that obtains the input signal. The driving signal table is composed of a plurality of different backlight driving signals, and the backlight driving signal determines the brightness of the light emitting element group. The first step and the second step described in the preceding paragraph can all be implemented by the above keyboard architecture. For example, the memory unit can set the complex input signal to be used to read the correspondence between the backlight driving signals from the driving signal table. The micro control unit determines a backlight driving signal outputted to the backlight unit from the driving signal table according to the input signal input by the user. Therefore, when the user presses each button, the micro control unit can determine the light-emitting brightness of each light-emitting component group in the backlight unit by using the key-in signal and the driving signal table, thereby enabling the backlight unit to provide the corresponding button Specific color. Or the keyboard can detect the generation of the input signal through the micro control unit, and read the backlight driving signal from the memory unit in a wheel sequence, and sequentially output the read backlight driving signal, thereby generating the brilliance of the wheel sequence change. Variety. Furthermore, a new drive signal table can be written to the memory unit via the software to change the color change corresponding to any of the keys. With the above technical features, the keyboard can be provided with variable backlight color variations.

In summary, the present case has the advantage of providing a color change of the backlight of the keyboard.

The present invention discloses a keyboard control method for generating brilliance changes and an illuminated keyboard for implementing the method, wherein the control method includes two control steps under the same technical idea. The first control step of the present invention is described below, wherein the control method of the present invention is for controlling an illuminated keyboard, the illuminated keyboard having a plurality of buttons for pressing to provide different input signals, a backlight unit including at least one light emitting component group, and A micro control unit (the implementation can be seen in Figure 3). First, the first control step of the present case is as shown in FIG. 1 , which includes the following steps: setting a driving signal table (step 1 in FIG. 1 ) and setting the output condition of each backlight driving signal (step 2 in FIG. 1 ). 101) scanning a key input signal generated by pressing the keyboard (step 3102 in FIG. 1), and reading a corresponding backlight driving signal from the driving signal table according to the input signal (step 4103 in FIG. 1). The backlight unit is driven by the backlight driving signal (step 5104 in FIG. 1). The driving signal table includes a plurality of backlight driving signals for controlling the brightness of the at least one light emitting component group, and the output condition of the backlight driving signal defines that each backlight driving signal in the driving signal table is associated with at least one keying signal. And detecting the input signal generation as a condition for outputting the backlight driving signal, that is, setting one or more input signals to read the corresponding backlight driving signal in the driving signal table. In the above steps, the backlight driving signal can be set as the output condition of the backlight driving signal; that is, the input signal generated by the plurality of buttons can be set to read the same backlight driving signal. For example, a button for pressing the English letters "A" to "E" may be preset to generate a first backlight driving signal, and a button for pressing the English letters "F" to "K" corresponds to generate a second backlight driving signal, and so on. And the first backlight driving signal and the second backlight driving signal respectively drive the backlight unit to generate different light brightness, or color, or a combination of brightness and color. The above example can further divide the plurality of keys of the keyboard into a plurality of button groups, and the input signals of the plurality of buttons in the same button group correspond to the same backlight driving signal, for example, all the numeric keys are grouped, and all the direction keys are divided into A group and the like, and pressing the buttons of each button group each produces a different backlight driving signal. Moreover, each backlight driving signal can also selectively detect a different single-keying signal as an output condition of the backlight driving signal, that is, each backlight generates a backlight driving signal that is different, so that when a different button is pressed, a backlight can be generated. Variable brightness and color changes. The light-emitting element group of the backlight unit can provide color light of a single color, and the brightness of the light-emitting element group is determined by the different backlight driving signals, so that the keyboard emits a single color of light and continuously changes the brightness as the user presses the button. The backlight unit can further distinguish the plurality of light-emitting component groups according to the color of the different light. The backlight unit can include a plurality of light-emitting component groups that generate color light of different colors, and determine the brightness of the light-emitting component groups according to the backlight driving signal. And by changing the brightness of each of the light-emitting element groups, the color of the light expressed on the keyboard after the light mixing is changed. The key input signal is a key code (KEY CODE) generated by pressing the button to contact a circuit board, or a key code corresponding to the key code (KEY CODE) in a message array. Regardless of whether the key input code is a key code (KEY CODE) or a corresponding character code, the two corresponding to a specific button can be used to read the corresponding backlight driving signal from the driving signal table.

The keyboard for implementing the control method of the present invention can be referred to FIG. 3. FIG. 3 shows a basic configuration of an illuminated keyboard, and FIG. 4 is a circuit block of the keyboard. As shown in FIG. 3 , the keyboard is provided with a circuit board 1 , a button group 3 for triggering the circuit board 1 to generate a key input signal, and a button group 3 disposed under the button group 3 . A backlight unit 2 is constructed. The button group 3 has a plurality of buttons, and the circuit board 1 has a signal contact corresponding to the button. After pressing the button, the signal contact can be triggered to form a corresponding key code (KEY CODE), the circuit board 1 A message processing unit 10 interprets the character code corresponding to the key code (KEY CODE) and outputs it to an information processing system 8 (shown in FIG. 4 or FIG. 5) through a line 12, wherein the information processing system 8 can be a computer. The backlight unit 2 may include a plurality of light-emitting element groups 22 that are distinguished by distinct light-emitting colors and a light guide plate 24 that is combined with the light-emitting element group 22. For example, the backlight unit 2 may include a light-emitting element group 22 that emits blue light, a light-emitting element group 22 that emits red light, and a light-emitting element group 22 that emits green light (but not limited to three colors of red, blue, and green, the backlight unit). 2 can still include a plurality of light-emitting element groups 22) of different colors, and the backlight unit 2 has drivers 21 for driving the light-emitting element groups 22 respectively (as shown in FIG. 4, wherein the light guide plate 24 is not used to turn on electrical signals; Shown in Figures 4 and 5). The keyboard further includes a memory unit 11 and a micro control unit 13 . The memory unit 11 stores a driving signal table. The driving signal table is composed of a plurality of different backlight driving signals, and the backlight driving signal determines the light emitting element group. The brightness of the light is turned on, and the plurality of key input signals are preset to read the correspondence between the backlight driving signals from the driving signal table, and the corresponding relationship is written into the memory unit 11. The micro control unit 13 is electrically connected to the circuit board 1 to detect the input signal. The micro control unit 13 reads the corresponding backlight driving signal from the driving signal table according to the input signal, and outputs a backlight driving signal to drive the The backlight unit 2 determines the light-emitting luminance of the plurality of light-emitting element groups 22 of the backlight unit 2. According to the above technical features, the backlight unit 2 can change the light-emitting brightness of each of the light-emitting element groups 22 according to the user pressing the button, and since the plurality of light-emitting element groups 22 provide different light colors, the color of the plurality of light-emitting element groups 22 will change. Mix to form different colors. In other words, the backlight unit 2 provides a color corresponding to the input signal according to the different keying signals triggered by the different keys, so that the user can have the effect of changing the brilliance when using the keyboard.

It can be seen that the key input code for correspondingly reading the driving signal table can be a key code (KEY CODE), or one key code corresponding to the key code (KEY CODE) in a message array, and two Both can be applied to correspondingly read the drive signal table. As shown in FIG. 4, the micro control unit 13 directly detects and captures the key code (KEY CODE) by the circuit board 1, and determines the output from the driving signal table to the backlight unit according to the key code (KEY CODE). 2 backlight drive signal. As shown in FIG. 5, the micro control unit 13 is connected to the message processing unit 10. The message processing unit 10 obtains the key code (KEY CODE) from the circuit board 1 and converts it into a corresponding character code. The micro control unit 13 captures the character code, and determines a backlight driving signal outputted to the backlight unit 2 from the driving signal table according to the character code. Both of the circuit structures shown in FIG. 4 and FIG. 5 can complete the foregoing control steps and are specifically applied to the keyboard.

Moreover, the driving signal table stored in the memory unit 11 is composed of a plurality of different backlight driving signals, wherein the backlight driving signal is a digital signal, and the encoding includes the brightness information of each of the light emitting element groups 22, and can drive multiple The light-emitting element group 22 is simultaneously illuminated. If the backlight unit 2 is exemplified by a group of three different types of light-emitting elements 22 (red, green, blue), the driving signal table can be illustrated as follows:

The above table 1 is a schematic table for illustrative use. In the implementation, the driving signal table is adjusted according to the number of the light-emitting element groups 22 of the backlight unit 2 and the number of buttons of the button group 3. Any backlight driving signal in Table 1 is mainly encoded by R _n , G _n , B _n (n represents the corresponding serial number), and is further divided into R _n and G by the micro control unit 13 through signal modulation. _The respective signals of _n , B _n and the like are given to the driver 21, and R, G, and B respectively represent the brightness information for driving the red, green, and blue light-emitting element groups 22, and the brightness information of different serial numbers can be driven to drive the corresponding light through the driver 21. The component group 22 provides different brightness, so the backlight driving signal R ₁ G ₁ B ₁ and the backlight driving signal R ₂ G ₂ B ₂ can respectively drive the red, green and blue light emitting element groups 22 to emit different brightnesses, respectively. The light provided by the light-emitting element group 22 can be mixed to provide color light of different colors, so that the different backlight driving signals drive the backlight unit 2 to provide color light of different colors. As with the control steps previously described, the backlight unit 2 can also provide a single color, and its brightness can be changed by a different backlight driving signal. Furthermore, the foregoing Table 1 is for exemplifying that the table to which the actual product is applied may vary depending on the number of the light-emitting element groups 22 and the number of buttons, and may also vary due to the input signal or the encoding format of the micro-control unit 13. For example, the brightness information of the red, green, and blue light-emitting element groups 22 can be stored into three tables, and the read form and signal can be selected according to the correspondence between the input signal and the three forms.

The above technical feature has provided a technique for pressing the button to drive the backlight unit 2 to emit a corresponding color light. However, when the user does not press the button group 3 (that is, the circuit board 1 does not provide a keying signal), the micro control unit 13 further The backlight unit 2 can be driven by a predetermined standby backlight signal, and the standby backlight signal determines the brightness of the plurality of light-emitting element groups 22 to provide a standby color light, so that the illuminated keyboard is in a normal state (the button group 3 is not pressed). ) Provides a predetermined color of light during standby. Further, the information processing system 8 can write the driving signal table to the memory unit 11 through the software to change any backlight driving signal of the driving signal table, so that the user can determine the generated by any button. Color light color.

Referring to FIG. 6 , the light emitting side of the backlight unit 2 is defined as a single light emitting area 23 , and the area of the light emitting area 23 includes the entire button group 3 , so that the entire keyboard button group 3 can be The color of the same color is emitted, and the color of the color provided by the backlight unit 2 is determined by the button pressed by the user and the corresponding backlight driving signal.

Referring to FIG. 7 , another embodiment of the present disclosure can further define a light emitting side of the backlight unit 2 as a first light emitting region 231 and a second light emitting region 232 , and the first light emitting region 231 and the second light emitting region. Each of the 232 covers a plurality of keys that are not repeated, and the plurality of light-emitting element groups 22 of the first light-emitting area 231 are driven by the backlight driving signal to change the brightness. At the same time, the micro control unit 13 can provide a fixed driving signal to drive the plurality of light emitting component groups 22 of the second light emitting region 232 to emit light of a preset color, thereby distinguishing the first light emitting region 231 and the fixed color of the color changing with the button triggering. The second light emitting region 232. In the case that some specific function buttons need to be marked with a special color light, the specific function button can be distinguished by distinguishing the second light-emitting area 232, so that the function button is obviously different from other buttons.

Moreover, this case has another control step under the same technical idea. Referring to FIG. 2, the control step includes: constructing a driving signal table including a plurality of backlight driving signals (step one 200 in FIG. 2), setting an output condition of the backlight driving signal (step 2 201 in FIG. 2), and scanning the The input signal generated by the pressing of the keyboard (step 3202 of FIG. 2), the backlight driving signal is sequentially outputted according to the input signal (step 4203 of FIG. 2), and the backlight unit is driven by the backlight driving signal (FIG. 2) Step 5 of 204 (204). Step 2: 201 is used to detect the input of the input signal as a condition for outputting the backlight driving signal, that is, the setting is as long as it is determined that the input signal has been generated, that is, the condition for outputting the backlight driving signal is met. Therefore, according to step 3202 and step 203, the plurality of backlight driving signals are sequentially outputted as the keyboard continuously generates the input signal, and the backlight unit is continuously driven by the different plurality of backlight driving signals to generate the brilliance change of the keyboard.

The control steps described in the preceding paragraph can also be implemented by the physical structure and circuit architecture of FIG. 3, FIG. 4 or FIG. The memory unit 11 stores a plurality of backlight driving signals, and the micro control unit 13 can determine the condition for outputting the backlight driving signal by detecting the input signal, and sequentially read the backlight driving from the memory unit 11. The signals drive the plurality of light-emitting element groups 22 of the backlight unit 2. The micro control unit 13 can detect the generation of the input signal from the circuit board 1 or the message processing unit 12 (as shown in FIG. 4 and FIG. 5), that is, the input signal can be the key code corresponding to each button. (KEY CODE) or the character code corresponding to the key code (KEY CODE). The micro control unit 13 can realize the function of reading and outputting the backlight driving signals in a wheel sequence through the control of a simple arithmetic circuit or firmware. This function is a well-known technology in the field of circuit control technology, and therefore will not be described again.
