Abstract: A terminal device and an infrared light transmission method are provided. A proximity light emission component and an infrared remote control emission component of the terminal device are in a shared mode. The proximity light emission component and the infrared remote control emission component share a same infrared lamp, lampshade, and appearance hole. A function of infrared remote control or a function of proximity light detection may be performed as required through one appearance hole, which can simplify hardware design and help to reduce costs. In addition, an infrared top path parallel to a screen of the terminal device and an infrared forward path perpendicular to the screen of the terminal device may be constructed based on an internal structure of the lampshade, and infrared light is transmitted through the infrared top path and the infrared forward path.

Abstract: This application discloses a hinge angle detection method and a related device, to accurately calculate a hinge angle of a foldable screen. A specific solution is applied to a foldable electronic device. The foldable electronic device includes a first screen and a second screen. A motion status of the electronic device and a relative position between a common axis and a horizontal plane are determined, and then a target algorithm is determined based on the motion status and the relative position. For the current motion status and relative position, accuracy of calculating a hinge angle by using the determined target algorithm is relatively high. The target algorithm includes an acceleration sensor algorithm, a gyroscope sensor algorithm, or a fusion algorithm. The fusion algorithm is an algorithm of fusing data of an acceleration sensor and data of a gyroscope sensor to calculate a hinge angle.

Abstract: An ambient light detection method and an electronic device are provided to prevent leaked screen light and/or screen transmittance from affecting ambient light detection. The method is applied to an electronic device. A first ambient light detection unit and a second ambient light detection unit are disposed in the electronic device. A first photosensitive area of the first ambient light detection unit is used to detect intensity of first light, and a second photosensitive area of the second ambient light detection unit is used to detect intensity of second light. The first light includes ambient light and leaked screen light, and the second light includes the leaked screen light. A calibration coefficient is further configured in the electronic device. The method includes: the electronic device determines intensity of the ambient light based on a first value, a second value, and the calibration coefficient.
