Abstract: A wireless charger includes a charging base, a connector, and a cable. The charging base is connected to the connector through the cable. The charging base includes a first housing and a transmitting coil disposed in the first housing. The wireless charger further includes a boost circuit and an inverter circuit. The boost circuit is disposed outside the first housing, and is configured to boost a direct current voltage signal input through the connector. The inverter circuit is disposed between the boost circuit and the transmitting coil, and is configured to convert a boosted direct current voltage signal into an alternating current voltage signal, and transmit the alternating current voltage signal to the transmitting coil. The transmitting coil is configured to convert electric energy of the alternating current voltage signal into electromagnetic energy for wireless transmission.

Abstract: Embodiments of the present invention provide a web page color setting method, a web browser, and a web server. The web page color setting method is used to set a color of a web page, where the web page includes a web page background and a content background, and a color of the web page background is different from a color of the content background. With the technical solutions provided in the embodiments of the present invention, setting the web page color will not influence the color of other contents displayed by the monitor. Moreover, the process of setting the web page color is quite simple, and easy to implement. Therefore, the technical solutions can solve the problem in the prior art that it is rather inconvenient to adjust the web page color by adjusting the display color of the monitor.

Abstract: A coil module is provided, which includes a coil, a magnetic conductive sheet, and an adapter plate. The magnetic conductive sheet is disposed on the coil. The adapter plate is disposed on the coil and is electrically connected to the coil. The adapter plate is configured to connect the coil. Through addition of the adapter plate, the adapter plate is first connected to the coil. The adapter plate is used for transition connection, to prevent a fault such as falling or poor contact of the coil, making it possible to implement integrated packaging of the coil module. A coil packaging structure and a wireless charging apparatus comprising the coil module are also provided.
