Title: Jeongkyoo Kim: Innovator in Display Technology

Introduction

Jeongkyoo Kim is a prominent inventor based in Yongin-si, South Korea. He has made significant contributions to the field of display technology, holding 2 patents that showcase his innovative approach to light-emitting devices and analog-to-digital conversion methods.

Latest Patents

One of his latest patents involves a pixel design that includes light-emitting devices and a display device featuring this pixel. Each pixel consists of a light-emitting portion with first light-emitting devices connected in a forward direction and second light-emitting devices connected in a reverse direction between two electrodes. The pixel circuit is designed to receive a data voltage synchronized with a scan signal, generating a driving current that is output to a first node. Additionally, a light-emitting circuit is controlled by a control signal to provide the driving current to the first light-emitting devices during a first emission period and to the second light-emitting devices during a second emission period.

Another notable patent is related to an analog-to-digital converter that includes a successive approximation converter, a voltage comparator, and a controller. This converter receives an analog input voltage and a reference voltage, determining the level of a voltage at a first node. It uses a successive approximation method to determine an output logic value corresponding to one bit of the N-bit output digital code during each approximation cycle. The voltage comparator generates a comparison logic value by comparing the first node's voltage with a second reference voltage, allowing the controller to terminate conversion and determine the N-bit output digital code when certain conditions are met.
