Title: Shwang-Shi Bai: Innovator in Light Emitting Devices and LCD Power Supplies

Introduction

Shwang-Shi Bai is a prominent inventor based in Tainan County, Taiwan. He has made significant contributions to the fields of light emitting devices and liquid crystal display (LCD) power supplies. With a total of 16 patents to his name, Bai's work has had a considerable impact on modern technology.

Latest Patents

One of Bai's latest innovations is a current-type driver of light emitting devices. This driver includes a power conversion circuit, a feedback module, and a control module. The power conversion circuit modulates and generates an output voltage based on a feedback signal, allowing it to sequentially drive multiple light emitting devices. The feedback module generates the feedback signal according to the output voltage and an adjusting signal during a first period, during which none of the light emitting devices is driven. The control module outputs the adjusting signal to the feedback module during this period, enabling the power conversion circuit to adjust the output voltage to a pre-drive voltage for the next light emitting device.

Another notable patent is the LCD power supply, which consists of an AC to DC converter circuit, a transformer, a DC to AC converter, and a feedback circuit. The AC to DC converter circuit connects to an AC power supply to generate a DC signal. The DC to AC converter then alternates the polarities of this DC signal to generate an AC signal on the secondary side of the transformer, supplying power to a load. The feedback circuit receives a first feedback signal indicative of the power supplied to the load and modulates the DC signal generated by the AC to DC converter circuit accordingly.
