Abstract: A latch mechanism for a battery unit includes a locking mechanism having a main body, at least one engaging mechanism, and at least one abutting portion. At least one tenon extends from the main body, and at least one ramp structure having an inclined surface extends from the main body. The engaging mechanism is arranged on a battery unit to receive the tenon. The abutting portion is arranged on the battery unit and has a contacting surface projected toward the inclined surface. When the locking mechanism is moved from the locking position to the released position, the contacting surface is abutted and lifted by the inclined surface, after the tenon has been completely disengaged from the engaging mechanism. The displacement of the contacting surface enables the battery unit to displace away from the inclined surface. The instant disclosure also includes an electronic device having the latch mechanism for a battery unit.

Abstract: A display apparatus includes a photoelectric sensor disposed on an inner side of a frame and located corresponding to a corner of a pixel area of a display panel in a predetermined position. When the display apparatus is turned on, the display panel provides a light spot at a corner of a current pixel area of the display apparatus corresponding to the photoelectric sensor, and a micro-control circuit compares an electronic signal received from the photoelectric sensor with a sample value.

Abstract: In a screen protection system and method, a first operation temperature of an electronic device is detected from each of one or more first temperature sensors, and a first ambient temperature is detected from a second temperature sensor, when a display screen is activated. Once there is no operation on the electronic device, a timer is started timing. Once the electronic device is being operated, a duration is temporarily stored and the timer is reset. If the duration is equal to a screensaver time, a second operation temperature of the electronic device is detected from each of the first temperature sensors, and a second ambient temperature is detected from a second temperature sensor. The method further determines whether the electronic device is currently being held by a hand of a user, according to the above-mentioned temperatures. If the electronic device is not being held by a hand of the user, the display screen is controlled to be in an inactive state.
