Embodiment Construction

[0014] The portable electronic device and its control method proposed by the present invention simultaneously utilize an ambient light sensor and a proximity sensor to determine the opening and closing status of the screen, thereby automatically controlling the electronic device. state.

[0015] Please refer to figure 1 , which shows a block diagram of an example of a portable electronic device according to an embodiment. The portable electronic device 100 is, for example, a laptop computer, which includes a control unit 110 , an ambient light sensor 120 , a distance sensor 130 , a digital processing system 140 and a panel 150 . In this embodiment, the control unit 110 includes a controller hub 112, such as a platform controller hub (platform controller hub, PCH) or a fusion controller hub (fusion controller hub, FCH). It is not limited, and depends on the design architecture of the control unit 110 . In addition, the digital processing system 140 is an optional element, wh...

Abstract

A portable electronic device including a control unit, an ambient light sensor, a proximity sensor and a panel is provided. The ambient light sensor is electrically connected to the control unit. The proximity sensor is electrically connected to the control unit. The panel is electrically connected to the control unit. When the portable electronic device is in a normal operation state and the panel is in an enabled state, if the ambient light sensor detects that the ambient light is dark and the proximity sensor detects that an object is close to a predetermined distance, the control unit switches the portable electronic device into one of a sleep mode, a hibernation mode or a shutdown mode, otherwise, the portable electronic device maintains in the normal operation state.

Description

technical field [0001] The invention relates to a portable electronic device and its control method. Background technique [0002] Traditional laptop computers (laptops) use the interaction between a magnet disposed on the top cover and a Hall sensor disposed on the base to determine whether the top cover is closed to detect panel switch or not. However, the magnet and the hall sensor not only occupy the space of the laptop computer, but also increase the manufacturing cost. Contents of the invention [0003] The invention relates to a portable electronic device and its control method, using a sensor to automatically detect the opening and closing state of the screen. [0004] According to a first aspect of the present invention, a portable electronic device is provided, including a control unit, an ambient light sensor, a distance sensor, and a panel. The ambient light sensor is electrically connected to the control unit. The distance sensor is electrically connected ...
