a laptop

technical field

The utility model relates to a notebook computer.

Background technique

At present, when the laptop is in hibernation or sleep state, or how many minutes are set in the power option to turn off the backlight, when the user comes back after leaving, he needs to control the mouse or keyboard to turn on the backlight of the display and continue to use it. , is more troublesome, therefore, if the backlight of the notebook computer is automatically turned on when the notebook computer reaches a certain distance, a better user experience will be achieved, and it will also be loved and sought after.

Utility model content

The technical problem to be solved by the utility model is to provide a notebook computer that can automatically turn on the backlight of the display when it is at a certain distance from the notebook computer.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A notebook computer, comprising: a display and a host, the display and/or the host is provided with a distance sensing unit for detecting the distance between the user and the notebook computer, the input side of the control unit in the host It is electrically connected to the distance sensing unit to send the detected distance information to the control unit, and the output side of the control unit is electrically connected to the display, so that when the received distance information is less than the preset distance, The control unit sends a control signal to the display to control the lighting of the backlight.

Wherein, the distance sensing unit is arranged around the camera on the display.

Wherein, the distance sensing unit is a distance sensor.

Wherein, the range of the preset distance is 50cm-100cm.

Wherein, the notebook computer further includes a brightness detection unit electrically connected to the input side of the control unit, configured to detect the brightness of the backlight of the display, and send the detected brightness information to the control unit, so The control unit sends an adjustment signal for adjusting the brightness of the backlight to the display according to the received brightness information and distance information.

Wherein, the brightness detection unit is a light sensor provided on the host or the display.

Compared with the prior art, the utility model has the beneficial effects of:

1. In the utility model, the distance between the user and the laptop is detected by the distance sensing unit, and when the user reaches the preset distance, the control unit controls the backlight of the display to light up, achieving a better user experience and being more intelligent ;

2. The utility model can also include a brightness detection unit. When the display brightness detection unit sends the detected brightness information to the control unit, the control unit adjusts the brightness of the display according to the brightness information and distance information, which can realize When the user comes back within a preset distance of the laptop, the display's backlight brightness reaches a standard brightness.

detailed description

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the utility model.

As shown in Figure 1, it is a structural block diagram of a notebook computer of the present utility model, which includes: a mutually hinged display 1 and a host (not shown in the figure), the display 1 and/or the host are provided with a The distance sensing unit 2 of the distance between the notebook computers, the input side of the control unit 3 located in the host computer is electrically connected with the distance sensing unit 2, to receive the distance information from the distance sensing unit 2, the output side of the control unit 3 is connected to the display 1 Electrically connected, so that when the distance information sent by the distance sensing unit 2 to the control unit 3 is less than the preset distance, the control unit 3 sends a control signal to the display 1 to control the backlight to turn on. That is to say, when the notebook computer is in a dormant or sleep state, and the distance information received by the control unit 3 is less than the preset distance, the control unit 3 can send a control signal to the display 1 to control the lighting of the backlight , does not require the user to manually operate to wake up the laptop, which is more intelligent and has a better user experience effect.

In this embodiment, the distance sensing unit 2 can be arranged around the camera on the display 1, and the distance sensing unit 2 can be a distance sensor using infrared monitoring, and the range of the preset distance in this embodiment can be 50cm-100cm.

In addition, as shown in Figure 2, it is a structural block diagram of a notebook computer in another embodiment of the present utility model, which can also include a brightness detection unit 4 electrically connected to the input side of the control unit 3, which is used to detect the brightness of the display 1. the brightness of the backlight, and send the detected brightness information to the control unit 3, and the control unit 3 sends an adjustment signal for adjusting the brightness of the backlight to the display 1 according to the received brightness information and distance information. That is, when the user is within the preset distance, the closer the user gets to the notebook computer, the greater the brightness of the backlight of the display of the notebook computer until the maximum brightness value set by the user himself. And the brightness detection unit 4 in this embodiment may be a light sensor located on the host or the display 1 .

In summary, the utility model detects the distance between the user and the notebook computer through the distance sensing unit, and when the user reaches the preset distance, the control unit controls the backlight of the display to light up, thereby achieving a better user experience, and more Intelligent; in addition, the utility model can also include a brightness detection unit, when the display brightness detection unit sends the brightness information it detects to the control unit, the control unit then adjusts the brightness of the display according to the brightness information and distance information, That is, when the user is within the preset distance, the closer to the notebook computer, the greater the brightness of the backlight of the display of the notebook computer, until the brightness maximum value set by the user himself, that is to say, this embodiment can realize when the user returns to the notebook computer. When the notebook computer is within the preset distance and gradually approaches the notebook computer, the brightness of the backlight of the display can gradually reach the standard brightness.
