Introduction

Seongjoo Lee is an inventor based in Yongin, South Korea, whose work focuses on display electronics and circuit technologies. He is associated with Samsung Display Co., Ltd. and is named on 2 patents.

Latest Patents

Lee’s listed patents address gate-driving and data-driving technologies for display devices.

- **Gate driver and electronic device.** This patent describes a gate driver with multiple stages. At least one stage uses a logic circuit to generate intermediate carry and carry-output signals from a carry input and clock signal, then produces an intermediate gate signal through logic operations. A level-shifting circuit adjusts the signal’s voltage, while a buffer outputs the gate signal or floats the gate output node according to a high-impedance control signal.

- **Data driver and display device including the same.** This patent describes a display device with a sub-pixel containing a capacitor, transistors, and a light-emitting element. A data driver selectively supplies a data voltage or reference voltage to the capacitor through a source channel, under the control of a timing controller.

Career Highlights

Lee’s listed patent work reflects contributions to display-panel circuitry, including gate-signal control and the delivery of data and reference voltages to sub-pixels. These technologies relate to the operation and control of display devices.
