A high voltage semiconductor device includes a well region of a first conductive type formed at a surface portion of a substrate, a gate electrode disposed on the well region, a source region formed at a surface portion of the well region adjacent to the gate electrode, a drain region formed at a surface portion of the well region adjacent to the gate electrode, and a drift region of a second conductive type disposed under the drain region.


According to embodiments, methods of scanning a touch panel and a touch integrated circuit (IC) for performing the same are disclosed. The touch IC simultaneously supplies a first driving signal having a first phase and a second driving signal having a second phase to a first driving line and a second driving line of the touch panel, respectively, and detects a sensing signal from a sensing line crossing the first driving line and the second driving line. The touch IC acquires a first scanning signal corresponding to the first driving line and a second scanning signal corresponding to the second driving line from the sensing signal.

A Schottky diode includes a drift region of a first conductive type formed at a surface portion of a substrate, an insulating layer disposed on the substrate and having an opening exposing a portion of the drift region, and a titanium silicide layer disposed on the portion of the drift region exposed by the opening.


Disclosed is a light emitting device driving apparatus configured to control a light emitting unit including light emitting devices or array(s) thereof connected in series. The light emitting device driving apparatus includes a rectifier configured to rectify an AC signal and supply to the light emitting unit a ripple current signal, and a sequential driving controller configured to generate a reference current, compare the reference current with a channel current from the light emitting unit, and selectively connect one of channel lines connected to respective output terminals of the light emitting devices or array(s) thereof. The sequential driving controller adjusts a level and/or value of the reference current based on the ripple current signal. The reference current is a current flowing between the first node and a ground potential.

Disclosed is an image sensor. The disclosed image sensor includes a pixel array including a plurality of unit pixels arranged in a matrix form having rows and columns, a binning sampling unit configured to output a binning sampling signal according to an average of signals from two or more unit pixels selected from among the unit pixels of each of the columns, and an analog-to-digital converter configured to convert the binning sampling signal to a digital signal. The selected unit pixels have different exposure times.
