Abstract
The utility model discloses a screen device in a poor light of cut -off computer, a serial communication port, include: button, time -recorder, embedded controller and BIOS, time -recorder, embedded controller and BIOS connect in order, the signal of telecommunication that the button produced when pressing is inputed the time -recorder, the time -recorder is configured as based on receiving the signal of telecommunication and start right the duration's of the signal of telecommunication timing, and, the time -recorder is configured as works as when duration reaches schedule time to embedded controller transmitting trigger signal, embedded controller be configured as based on triggering signal sends the closed signals that is shaded to BIOS, and BIOS is configured as according to receiving closed signals in a poor light comes the screen of cut -off computer to be shaded. The utility model discloses screen device in a poor light of cut -off computer can save the keyboard space to convenience of customers uses.
Description
Technical field
The utility model relates to field of computer technology, is specifically related to a kind of device of screen backlight of shutting down computer.
Background technology
On the keyboard of some current notebook computers, being provided with a button for closing screen backlight, being also provided with two buttons being respectively used to screen backlight brightness be heightened, turn down in addition.Namely, for screen backlight, employ three buttons to regulate its function.Along with the development of current computer product technology, there are the needs function of keyboard constantly expanded.And only screen backlight this, just occupy three buttons, occupy keypad space.And when user wants to close backlight time, carefully will distinguish which is the button of closing backlight, which is the button regulating backlight size, and it is convenient not to use.
Utility model content
In view of the foregoing defects the prior art has, the utility model provides a kind of device of screen backlight of shutting down computer, and is no longer provided with the button of independent closedown screen backlight, thus saves keypad space.
The device of screen backlight of shutting down computer of the present utility model comprises: button, timer, embedded controller, and BIOS, described timer, embedded controller, and BIOS connects in turn, the electric signal produced when described button is pressed is imported into described timer, described timer is configured to the timing starting the duration to described electric signal based on the described electric signal received, and, described timer is configured to send trigger pip when the described duration reaches the schedule time to described embedded controller, described embedded controller is configured to send backlight shutdown signal based on described trigger pip to BIOS, BIOS is configured to the screen backlight of shutting down computer according to the described backlight shutdown signal received.
Preferably, described timer and described embedded controller are integrated structure.
Preferably, described button is the key that screen intensity is turned down by computer keyboard.
Preferably, described button is the key that screen intensity is turned down by graphoscope.
The utility model has following beneficial effect:
1, the space on keyboard can be saved, originally need three buttons, only need two now.
2, user does not need to take time to look in addition again and closes the button of backlight.
3, length goes to turn off backlight by the button for turning down backlight, more intuitively.
Accompanying drawing explanation
Fig. 1 is the structural representation of the device of the screen backlight of shutting down computer of the utility model embodiment.
Fig. 2 is the structural representation of the device of the screen backlight of shutting down computer of a preferred embodiment of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
What illustrate is, " button " alleged in the utility model is the button for computing machine well-known to those skilled in the art, comprise: the conventional keys (button as on display) on other hardware devices of the button on computer keyboard or computing machine, it is characterized in that when the button is pressed, computing machine can be caught the electric signal produced when being pressed by this button and also can be processed accordingly.
Fig. 1 is the structural representation of the device of the screen backlight of shutting down computer of the utility model embodiment.As shown in Figure 1, the device of the screen backlight of shutting down computer of embodiment, comprising: button 11, timer 12, embedded controller 13 and BIOS14, and its Timer 12, embedded controller 13 and BIOS14 connect in turn.
The electric signal produced when button 11 is pressed is imported in timer 12, timer 12 starts the timing of the duration to electric signal thus, trigger pips are sent to embedded controller (EmbeddedController is called for short EC) 13 when the duration reaches the schedule time (such as 3 seconds, 4 seconds etc.).
Embedded controller EC is the conventional controller on computing machine (as notebook computer, desk-type integrated computer), it is integrated on computer motherboard, it is the bottom hardware for managing electrical power, when after the trigger pip that it receives from timer 12, namely backlight shutdown signal Qevent is sent, to notify the screen backlight that BIOS shuts down computer to BIOS14.
BIOS (Basic Input or Output System (BIOS)) is also the customary components on computer motherboard, its can the specifically opening and closing of computer for controlling screen backlight, brightness size.The Qevent that BIOS can send according to EC closes screen backlight.
Known by this embodiment, without the need to arranging the button of independent closedown screen backlight, achieving the function that backlight is closed, saving keypad space.
Fig. 2 is the structural representation of the device of the screen backlight of shutting down computer of a preferred embodiment of the present utility model.In this embodiment, timer 12 and EC13 are integrated structure.
In a preferred embodiment, button 11 is the key that screen intensity is turned down by computer keyboard.Namely, be incorporated into by screen closing function on key screen intensity turned down, therefore user only need press the button turned down by screen and reaches the schedule time (as 3 seconds), just can realize closing screen backlight, this set is relatively more directly perceived, and user uses can be more convenient.
In another embodiment, button 11 is the key that screen intensity is turned down by graphoscope, utilizes the program, and user presses and the button that screen is turned down reaches by display the schedule time (as 3 seconds, 4 seconds etc.), also can realize closing screen backlight.
Certainly; the above is only preferred implementation of the present utility model; for those skilled in the art; under the prerequisite not departing from spirit of the present utility model and principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
Claims (4)
1. a device for the screen backlight of shutting down computer, is characterized in that, comprising: button, timer, embedded controller and BIOS, and described timer, embedded controller and BIOS connect in turn,
The electric signal produced when described button is pressed is imported into described timer, described timer is configured to the timing starting the duration to described electric signal based on the described electric signal received, and, described timer is configured to send trigger pip when the described duration reaches the schedule time to described embedded controller, described embedded controller is configured to send backlight shutdown signal based on described trigger pip to BIOS, and BIOS is configured to the screen backlight of shutting down computer according to the described backlight shutdown signal received.
