WIRELESS CHARGING THROUGH A DISPLAY

Smart overview of the Invention

A mobile computing device is designed with innovative wireless charging capabilities that allow energy transfer through its display. This device integrates a display, a battery, and a wireless charging coil capable of both transmitting and receiving electrical energy through the display. The circuitry within the device facilitates battery charging via the energy harnessed by the coil.

Background

Traditionally, wireless charging in devices like smartphones and tablets occurs through the back panel, which is typically non-metallic. These devices can either receive power as charging sinks or provide power as charging sources. However, this configuration may not always be ideal due to the necessity of having the display face up or down during charging.

Innovation

This technology introduces a mobile computing device that can perform wireless charging through its display. The device can receive power from a charging pad even when placed face down, preventing distractions from the display illumination. Modifications to components such as the metallic shielding layer enable this capability by creating a cutout over the wireless charging coil.

Technical Details

• Display: Renders images using technologies like LCD, LED, or OLED.
• Shielding Layer: Provides electromagnetic shielding and may have sections cut out to facilitate through-display charging.
• Wireless Charging Coil: Transduces between magnetic fields and electrical current, compliant with standards like Qi.
• Circuitry: Manages power flow to and from the battery, integrating DSPs, microprocessors, or ASICs.
• Battery: Stores and supplies electrical power using technologies such as lithium-ion or nickel-metal hydride.

Implementation

The device's design allows for modifications that enable through-display charging. For instance, a section of the shielding layer directly above the wireless charging coil is removed to facilitate energy transfer. This section can be decorated for aesthetic purposes while maintaining functionality. Such innovations ensure seamless integration of charging capabilities without compromising the device's usability or appearance.
