Title: Ho-Jin Byun: Innovator in Display Technology

Introduction

Ho-Jin Byun is a notable inventor based in Suwon, South Korea. He has made significant contributions to the field of display technology, holding 2 patents that showcase his innovative approach to circuit design.

Latest Patents

One of his latest patents is a duty cycle alteration circuit. This circuit can simply alter the duty cycle of a pulse by using a Schmitt circuit in a monitor. The duty cycle alteration circuit includes a microcomputer for outputting a waveform amplifying ratio control signal, an amplifying circuit for inputting and amplifying the waveform amplifying ratio control signal outputted by the microcomputer or a triangular wave, and a Schmitt circuit for establishing a logic “high” level and a logic “low” level centering around a reference level according to the amplified triangular wave supplied from the amplifying circuit. This circuit changes the duty cycle based on the logic “high” and “low” levels and outputs a rectangular wave with an altered duty cycle.

Another significant patent by Ho-Jin Byun is a display device having a set protection function upon generation of an abnormal voltage. This device includes a horizontal deflection circuit for providing a horizontal signal to a deflection yoke connector, a high voltage output circuit for supplying a high voltage to an anode in accordance with an oscillating signal applied from the horizontal deflection circuit, and a power supply circuit for supplying power to the horizontal deflection circuit. An abnormal voltage detector is also included, which is disposed between the deflection yoke connector and the high voltage output circuit and the power supply circuit. This detector checks whether the deflection yoke connector is connected and whether a part of the high voltage output circuit is damaged, thereby controlling the power output of the power supply circuit based on the detected results.
