POLARITY SWITCHING POWER SUPPLY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240195280 titled 'POLARITY SWITCHING POWER SUPPLY DEVICE

The patent application relates to a power supply device designed to control a liquid crystal display (LCD) panel efficiently and reliably. The device includes a positive-side switching converter, a negative-side switching converter, and a controller.

• The controller alternates the polarity of a bias voltage across a positive output node and a negative output node by switching between forward-bias and reverse-bias states in an active-bias mode.
• In a neutral-bias mode, the controller provides a neutral bias voltage across the positive and negative output nodes.

Potential Applications: - This technology can be applied in various electronic devices that use LCD panels, such as televisions, monitors, and smartphones.

Problems Solved: - The power supply device addresses the need for efficient and reliable control of bias voltages in LCD panels.

Benefits: - Improved power efficiency and reliability in controlling LCD panels. - Enhanced performance and longevity of electronic devices utilizing LCD technology.

Commercial Applications: - The technology can be utilized by manufacturers of electronic devices with LCD panels to improve energy efficiency and overall performance, potentially leading to cost savings and increased customer satisfaction.

Questions about the Technology: 1. How does the power supply device improve the performance of LCD panels? 2. What are the key advantages of using a positive-side and negative-side switching converter in this context?

Original Abstract Submitted

examples are disclosed that relate to a power supply device for controlling a liquid crystal display (lcd) panel in a reliable and power efficient manner. in one example, the power supply device includes a positive-side switching converter, a negative-side switching converter, and a controller. in an active-bias mode, the controller controls the positive-side switching converter and the negative-side switching converter to alternate a polarity of a bias voltage across a positive output node and a negative output node by alternating between a forward-bias state and a reverse-bias state. in a neutral-bias mode, the controller provides a neutral bias voltage across the positive output node and the negative output node.
