Latest Patents

One of Jong-Ho Lim's latest patents is a "Lamp driving apparatus for liquid crystal display device having high contrast ratio." This technology implements a high contrast ratio that cannot be achieved through traditional analog dimming or burst dimming methods. It selectively turns off lamps on the LCD device, utilizing a control unit that outputs control signals and video data. The system includes a gate driving unit that supplies scan signals to gate lines and a data driving unit that provides data voltage to data lines. The backlight driving unit controls the optical amount by managing the tube current supplied to the lamps, allowing for high brightness in dark areas by selectively turning off some lamps.

Another significant patent is related to a "Liquid crystal display device." This invention allows for the driving of a light-emitting diode (LED) to turn on a fluorescent lamp in darkness using an induced voltage, minimizing fabrication costs and power consumption. The LCD device drives the fluorescent lamp while simultaneously powering the LED, which helps to turn on the fluorescent lamp more quickly in low-light conditions.
