Latest Patents

Tzu-Chieh Lai's latest patents include a GOA circuit and a liquid crystal display device applied to liquid crystal displays. The GOA circuit comprises a plurality of cascaded shift register units, where an (N)th level shift register unit is controlled to charge an (N)th level scanning line accordingly. This innovative design includes a pull-up circuit, a pull-down circuit, a pull-down sustain circuit, a pull-up control circuit, a down transfer circuit, and a bootstrap capacitor. By replacing scanning lines with a constant voltage VDD or two voltages, the loading of scanning lines is reduced, minimizing risks associated with wiring step-by-step. Additionally, the forward-scanning and backward-scanning operations are accomplished effectively.

Another notable patent is the row driving circuit for an array substrate and liquid crystal display device. This invention features an n-th stage array substrate row driving unit that comprises an (n−3)-th and an (n−2)-th stage signal input terminal along with a pull-up controlling unit. The pull-up controlling unit is a first thin film transistor connected to the (n−2)-th and (n−3)-th stage signal input terminals. This design ensures that the peak voltage of the (n−3)-th stage signal input terminal is twice that of the (n−2)-th stage signal input terminal, thereby avoiding threshold voltage shifts of the TFT elements and improving output stability.
