Latest Patents

One of Gun-Won Lee's latest patents is a test circuit designed for identifying open and short circuit defects in a liquid crystal display. This innovation modifies the display to support exhaustive, quantitative testing after assembly while requiring only a limited number of test pads. Multiple data lines are connected to form data line blocks on-board the display but outside the active area of the array for testing purposes. Each data line block is connected to a corresponding test pad via a control switch, which is preferably formed of thin-film transistors (TFTs) and controlled by test gate lines arranged in a matrix form.

Another significant patent by Lee is a probe control method for leveling probe pins during a probe test sequence. This method is particularly useful for testing large area substrates, such as thin film transistor circuit substrates. The process includes connecting a pin of a probe station to a resistance material, measuring the resistance between adjacent pins using a resistance measuring device, and leveling the probe pins using a pin control device at the probe station.
