Abstract: A luggage board for a vehicle includes a core layer; a first layer covering a portion of the core layer; and a second layer covering a remaining portion of the core layer except for a region covered by the first layer. End portions of the first layer and the second layer disposed on a side surface of the core layer are bonded to each other.

Abstract: Disclosed are a semiconductor device (1) including a MOSPET region and an integrated diode region, and a manufacturing method thereof. More particularly, a semiconductor device (1) including a silicon carbide (SiC) MOSPET region and an integrated Schottky bather diode that reduce forward voltage drop (Vf), device area, and switching oscillation resulting from parasitic inductance are disclosed.

Abstract: A non-painted thermoplastic resin composition including viscose rayon so as to embody a marble pattern and a method for making it are disclosed. The viscose rayon is included in the thermoplastic resin composition to minimize the deterioration of physical properties while minimizing weld lines and flow marks during an extrusion process, and a luxurious outer appearance of a marble pattern is embodied without additional post-processing or painting process. The non-painted thermoplastic resin composition includes 80-90 parts by weight of a thermoplastic resin composition, 0.1-5 parts by weight of a carbon fiber, and 0.1-3 parts by weight of viscose rayon based on 100 parts by weight of the entire resin composition. The viscose rayon provides an effect of minimizing weld lines and flow marks during injection, improving physical properties, and providing the luxurious appearance of the marble pattern.

Abstract: An amplifying circuit of a display device including a plurality of pixels includes an input unit, a bias unit, and an output unit. The input unit is coupled between a first power source for supplying a first voltage and a second power source for supplying a second voltage, receives a first input signal and a second input signal, and is controlled by the first and second input signals. The bias unit receives a bias voltage for operating the input unit, and includes a first node and a second node controllable by the input unit. The output unit applies an output voltage to a pixel by using a first output transistor turned on/off by a signal applied to the first node and a second output transistor turned on/off by a signal applied to the second node, and the first output transistor is a different type to the second output transistor.

Abstract: The present invention relates to a liquid crystal display, a driving device thereof, a digital to analog converter, and an output voltage amplifying circuit.

Abstract: An output voltage amplifier, and a driving device of a liquid crystal display using the same are disclosed. The output voltage amplifier includes: an amplifying unit to generate first and second signals corresponding to a gray voltage input to a first input terminal and a feedback signal input to a second input terminal, and to output a first voltage by using first and second switches driven to be on or off according to the first and second signals; an output unit to apply the first and second data signals to the first and second pixels by using third and fourth switches turned on or off according to the first and second signals; and a feedback circuit unit to selectively supply one of the first voltage and the first and second data signals to the second input terminal. Heating characteristics and a slew rate can be improved.
