Abstract: A fan speed control method performing by a baseboard management controller includes following steps: obtaining a first temperature from a first temperature sensor, determining a first rotational speed according to the first temperature and a proportional-integral-derivative (PID) equation, wherein a proportional term of the PID equation is: ? 0 t f ? ( E ? V ? ( t ) , p ) [ EV ? ( t ) ] 2 ? d ? t - ? 0 t - ? ? t f ? ( E ? V ? ( t - ? ? t ) , p ) [ EV ? ( t - ? ? t ) ] 2 ? dt ; where t denotes time, ?t denotes an interval time, EV(t) denotes an error between the first temperature and a set temperature when the time is t, EV?(t) denotes a first derivative of EV(t), ƒ(EV(t),p) denotes a coefficient of the proportional term, and controlling said at least one fan according to said at least the first rotational speed.

Abstract: The present disclosure provides an information display method and apparatus, a medium, and an electronic device.

Abstract: An electronic device includes: a battery, a mainboard, and a housing. The battery is connected to the mainboard, the mainboard is provided with a first controller, the battery and the mainboard are installed in a cavity of the housing, and the housing includes a rear cover. The rear cover includes an electrochromic layer, the electrochromic layer is connected to the mainboard, the first controller is configured to control whether to power on the electrochromic layer, and a color displayed on the electrochromic layer when the electrochromic layer is powered on is different from a color displayed when the electrochromic layer is not powered on. The rear cover can change, by controlling a power-on and power-off status of the electrochromic layer, a color displayed on the electrochromic layer, and further change a color displayed on the rear cover, without changing a decorative film.

Abstract: An enclosure (200) is provided. The enclosure (200) includes a substrate (1) and composite film layer (2) coated onto the substrate (1). A thickness of the composite film layer (2) gradually decreases or increases along a first direction (X), and a difference between film thicknesses of any two regions arranged along the first direction (X) on the composite film layer (2) is less than or equal to 350 nanometers, so that the enclosure (200) presents a gradient color of a wavelength ranging from 400 nanometers to 760 nanometers. A mobile terminal (100) having the enclosure (200) and a sputter coating apparatus (300) are further disclosed.

Abstract: An enclosure of a mobile terminal and a sputter coating apparatus for making the same are provided. The enclosure includes a substrate and a composite film layer coated onto the substrate. The composite film layer has a thickness changing along a first direction. A difference in thickness between any two regions arranged along the first direction of the composite film layer is less than or equal to 350 nanometers. The enclosure has a spatially varying color corresponding to a wavelength between 400 nanometers and 760 nanometers.

Abstract: Embodiments of this application provide a middle frame, a battery cover, and an electronic device. The electronic device may include a mobile or fixed terminal with an edge frame or a housing, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a POS machine, a personal digital assistant (PDA), an event data recorder, a wearable device, a virtual reality device, a wireless USB flash drive, a Bluetooth speaker/headset, or a vehicle-mounted device. Two types of materials: ceramics and plastic, are used to form a middle frame and a battery cover, thereby reducing a weight of the electronic device. This resolves a problem that is of a relatively large weight of an existing electronic device and that is caused when a pure ceramic middle frame and a pure ceramic battery cover are used in the electronic device.
