Latest Patents

Park’s listed recent patents address DC-DC conversion and short-circuit protection in display systems.

The patent titled “DC-DC Converter and Display Device Including the DC-DC Converter, and Electronic Device Including the Display Device” describes a converter with two switching elements, an inductor, and a switching controller. The controller generates switching signals, responds to reset signals, and selects low-power or normal operation according to panel current and a threshold. The threshold is adjusted based on the switching control signal.

“Display Device Having a Short Circuit Protection Part to Output a Shutdown Signal” describes a voltage generator and a protection circuit that monitors a converter’s output. The converter pre-charges the output, maintains its level, and then boosts it to produce a voltage. If the output falls below a reference level during the maintenance period, the protection circuit issues a shutdown signal.
