Latest Patents

Choi’s listed patent, “Method for Fabricating a Thin Film Transistor Array Substrate with a Thinned Protective Film over a Storage Capacitor,” describes a TFT array substrate and a method for making it. The design places a TFT where gate and data lines intersect, with a protective film covering the transistor and data line. A contact hole allows a pixel electrode to connect to the TFT’s drain electrode.

The invention focuses on the storage capacitor. It removes some or all of the protective film in the capacitor area, leaving either no protective film or a thinner layer there than over the TFT. This arrangement is intended to support the capacitor structure while retaining protective coverage over key transistor components.

Career Highlights

Choi’s listed patent connects his work with display-substrate fabrication at LG Display Co., Ltd. The disclosed approach concerns the arrangement of insulating and protective layers in a TFT array, particularly around the storage capacitor.

Collaborations

Sung Jin Kim is identified as Choi’s coworker. The available information does not specify whether Kim was a co-inventor or describe a particular collaboration on the patent.

Conclusion

Woo Young Choi’s listed invention addresses a specific challenge in TFT array substrate design by thinning or removing protective film over a storage capacitor while maintaining coverage over the TFT.
