Abstract

A display device includes a panel unit, an image shooting unit and a processing unit. The image capturing unit is used to capture the eyes of a user to generate image data. The processing unit is electrically connected to the panel unit and the image capturing unit, and controls the panel unit to be turned on in an on mode, and controls the panel unit to be turned off in an off mode. When the processing unit is in the open mode and it is determined that the user's eyes are closed according to the image data, the processing unit starts to count down a predetermined countdown time. When the processing unit is in the countdown, and it is determined that the user's eyes are open according to the image data, the processing unit terminates the countdown. When the predetermined countdown time is completed, the processing unit switches to the shutdown mode to control the panel unit to shut down.

Description

Display device and method for automatically turning off the display device

The present invention relates to a display device, in particular to a display device including an image capturing unit. The invention also relates to a method for automatically turning off the display device.

A display device (such as a TV) is a common and commonly used household appliance, and it consumes considerable energy. Many users often see falling asleep in front of the TV. At this time, the TV continues to consume energy because it is not turned off. Therefore, how to develop a new display device that can improve the aforementioned waste of energy has become the subject of further discussion in the present invention.

Therefore, the purpose of the present invention is to provide a display device.

Another object of the present invention is to provide a method for automatically turning off the display device.

Therefore, the display device of the present invention includes a panel unit, an image capturing unit, and a processing unit. The image capturing unit is used to capture the eyes of a user to generate image data. The processing unit is electrically connected to the panel unit and the image capturing unit, and controls the panel unit to be turned on in an on mode, and controls the panel unit to be turned off in an off mode. When the processing unit is in the open mode and it is determined that the user's eyes are closed according to the image data, the processing unit starts to count down a predetermined countdown time. When the processing unit is in the countdown, and it is determined that the user's eyes are open according to the image data, the processing unit terminates the countdown. When the processing unit counts down the predetermined countdown time, the processing unit switches to the shutdown mode to control the panel unit to shut down.

In some implementation aspects, when the processing unit is in the countdown, the processing unit controls the panel unit to display the time in the countdown.

The method for automatically turning off the display device of the present invention is implemented by a display device that includes a panel unit, an image capturing unit, and a processing unit. The image capturing unit is used to capture the eyes of a user to generate image data , The processing unit controls the panel unit to open in an open mode, and controls the panel unit to close in a closed mode, the method includes: when the processing unit is in the open mode, and judging the user according to the image data When the eyes of the user are closed, the processing unit starts to count down a predetermined countdown time; when the processing unit is in the countdown, and the user’s eyes are judged to be open according to the image data, the processing unit terminates the countdown; and when the processing After the unit counts down the predetermined countdown time, the processing unit switches to the shutdown mode to control the panel unit to shut down.

The effect of the present invention is: by starting to count down the predetermined countdown time when the processing unit judges that the user's eyes are closed according to the image data, and by switching to the predetermined countdown time when the processing unit finishes counting down the predetermined countdown time In the off mode, the panel unit is controlled to close, thereby achieving the effect of energy saving.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numbers.

Referring to FIG. 1, an embodiment of the display device 100 of the present invention includes a panel unit 1, an image capturing unit 2 and a processing unit 3.

The panel unit 1 is, for example, a liquid crystal panel unit, but it is not limited to this. The image capturing unit 2 is used to capture the eyes of a user to generate image data. The image capturing unit 2 is, for example, a camera, but not limited to this.

The processing unit 3 is electrically connected to the panel unit 1 and the image capturing unit 2, and controls the panel unit 1 to be turned on in an on mode, and controls the panel unit 1 to be turned off in an off mode. The processing unit 3 may include (but is not limited to) a single-core processor, a multi-core processor, a dual-core mobile phone processor, a microprocessor, a microcontroller, a digital signal processor (DSP), and an on-site At least one of a programmable logic gate array (FPGA), a special application integrated circuit (ASIC), and a radio frequency integrated circuit (RFIC).

The display device 100 is a television in this embodiment, but not limited to this. The display device 100 may also be a display, for example.

1 and 2, the following describes the flow of the method for automatically turning off the display device 100. First, as shown in step S01, the processing unit 3 operates in the open mode and the control panel unit 1 is turned on. In other words, the display device 100 is in an on state.

Then, as shown in step S02, the processing unit 3 determines whether the user's eyes are closed according to the image data, if not, step S02 is executed again, and if so, step S03 is executed next.

In step S03, when the processing unit 3 is in the open mode and the user's eyes are closed according to the image data, the processing unit 3 starts to count down a predetermined countdown time (for example, 1 minute). In this embodiment, when the processing unit 3 is in the countdown, the processing unit 3 also controls the panel unit 1 to display the time in the countdown.

Then, as shown in step S04, when the processing unit 3 is in the countdown, the processing unit 3 also determines whether the user's eyes are open according to the image data, if yes, execute step S05, if not, execute step S06.

Step S05 is that the processing unit 3 terminates the countdown, and then executes step S02 again.

In step S06, the processing unit 3 judges whether the predetermined countdown time has been counted down, if not, step S04 is executed again, and if so, step S07 is executed.

Step S07 is that when the processing unit 3 counts down the predetermined countdown time, the processing unit 3 switches to the shutdown mode and controls the panel unit 1 to shut down. In other words, the display device 100 is switched from the open state to a closed state. To achieve the effect of energy saving.

In summary, the display device 100 of the present invention starts to count down the predetermined countdown time when the processing unit 3 determines that the user's eyes are closed according to the image data, and when the processing unit 3 counts down the predetermined countdown time When the time is over, switch to the shutdown mode and control the panel unit 1 to shut down, so as to achieve the effect of energy saving, so the objective of the invention can indeed be achieved.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to Within the scope covered by the patent of the present invention.
