Latest Patents

Yung Fong Kao holds a patent for an "Organic light-emitting diode display with passive leakage-reducing structures." This invention involves an array of OLED pixels, where OLED layers are interposed between a cathode and an anode. By applying voltage to the anode of each pixel, the emitted light can be controlled. The design addresses the challenge of leakage current that can occur between neighboring anodes, which can lead to cross-talk. To mitigate this issue, the display incorporates both active and passive leakage-mitigating structures. The passive structures feature an undercut that creates discontinuities in the OLED layers, while the active structures may include a conductive layer that drains leakage current to ground or a gate electrode modulator that controls current flow laterally.
