Latest Patents

Dong-Hyon Ki holds two patents that showcase his expertise in display technology. The first patent is for a display apparatus and method thereof. In this invention, a gate driver receives at least one clock to sequentially provide gate lines in a display panel with a gate signal in a high state corresponding to a high interval of the clock. The gate driver includes a plurality of amorphous silicon transistors and is formed in the display panel through a thin film process. The clock has a delay time of about 2.0 µs or less. If the delay time of the clock is reduced to less than about 2.0 µs, a threshold voltage margin of the transistors increases, preventing the gate driver from malfunctioning during high-temperature aging processes.

The second patent is for a gate driver and display apparatus having the same. This invention comprises n shift registers, where n is an integer equal to or larger than 1. Each of the n shift registers includes a start stage that outputs a gate signal and begins its operation in response to a start signal. Additionally, a plurality of subsequent stages are connected in sequence, which sequentially output a plurality of gate signals in response to a signal output from the start stage. Notably, at least one stage of the subsequent stages is reset by the start signal.
