Latest Patents
One of his latest patents is for an electronic device and display driver chip. This invention includes a substrate and a display driver chip bonded on the substrate. The display driver chip consists of multiple operational amplifiers, each featuring a first stage and a second stage. The first stage has a first power input terminal, while the second stage includes a first power input terminal and an output terminal for outputting an output voltage. The first power input terminal of the first stage is connected to a first metal trace of the substrate, and the first power input terminal of the second stage is connected to a second metal trace of the substrate. Both power input terminals are provided with a first voltage level.
Another significant patent by Ping Chen is related to a driving circuit of display apparatus and its driving method. This driving circuit includes an operational amplifier (OP) with multiple input terminals, a digital-to-analog converter (DAC), and a multiplexer that connects the OP and the DAC through several switches. Additionally, it features a boosting module designed to decrease the equivalent time constant between the DAC and the OP, thereby increasing the output slew rate of the OP during a boosting period, which is enabled before the OP reaches a steady state.
