Latest Patents

Changseung Woo's latest patents include a display device and a method of manufacturing the same. This display device is optimized to operate in a low frame rate mode under specific predetermined conditions. To minimize pixel discharge during this mode, the device employs thin-film transistors (TFTs) with a metal oxide semiconductor layer. Additionally, it features an optical alignment layer with upper and lower portions that have different resistivities. A passivation layer is also included to compensate for the low resistivity of the lower portion of the optical alignment layer, effectively reducing various visual defects associated with pixel discharge.

Another notable patent is for a thin film transistor substrate that incorporates a color filter layer. This substrate consists of multiple pixel areas arranged in a matrix on a substrate. Each pixel area includes an aperture area and a non-aperture area, with a first and second color filter stacked at the non-aperture area. The design also includes an overcoat layer, a semiconductor layer, a gate insulating layer, and a gate electrode, along with a third color filter and source and drain electrodes.
