Latest Patents

Among his latest patents is a "Data driving apparatus for liquid crystal display device having a control switch for precharging an output channel." This invention includes an output buffer that buffers and outputs a data voltage input from a digital-analog converter. The output buffer features an input amplifier that amplifies and outputs current proportional to the data voltage. Additionally, it includes an outputter that supplies a data voltage corresponding to the input data voltage to an output channel using charging and discharging current proportional to the output current from the input amplifier. A control switch unit is connected between the input amplifier and the outputter, driving the outputter in a switching mode to precharge the output channel before the data supplying period. A mode controller manages the control switch unit in response to an input control signal.

Another notable patent is the "Method and apparatus for moving call." This invention provides an operation method and apparatus for a terminal to facilitate call movement. The method involves receiving a call move request signal from a first device in voice communication with a second device. The terminal transmits a call state request signal for the first device using the registration information. If the call state for the first device is not a call, the terminal establishes a wireless connection with the first device and performs voice communication with the second device through this connection.
