Abstract: Disclosed is an apparatus and a method, in which gray levels are realized in such a manner that a pixel is supplied with a constant current instead of a voltage and charging duration (required for inputting data until a gate is turned on/off) is time-divided by the number of gray levels to be realized. The apparatus includes a current supplier for supplying a current filling a pixel, a buffer for latching display data, an adder for adding currently-input display data and display data latched the buffer, a pulse generator for receiving data outputted from the adder and delivering a switch-on pulse having a pulse width corresponding to the outputted data to the current supplier, and a controller for controlling the current supplier, the adder, and the pulse generator.

Abstract: Provided is a wave-shaped coating structure comprising an S/R coating layer coated on TAB/COF. The S/R coating layer is provided with a plurality of recesses for making the edge of the layer to be wave-shaped. The width of the recess is 1-10 units of lead. The shape of the recess is rectangle, trapezoid, U-shape or V-shape.

Abstract: An infrared gas burner for a gas cooker including a mixing tube arranged between a gas valve and a burner unit and adapted to mix gas supplied from the gas valve with air, a support member for supporting a ceramic plate within the burner unit in such a manner that the gas mixture emerging from the mixing tube passes through flame holes of the ceramic plate, a temperature control unit adapted to measure a temperature of flames generated by the burner unit, thereby controlling the amount of gas supplied to the burner unit based on the measured temperature, and a cover unit disposed over the burner unit and adapted to transfer infrared radiant heat and exhaust heat generated at the burner unit to a cooking pot laid thereon. The mixing tube is configured to mix gas with air in an optimum state for the combustion of the gas while uniformly distributing the gas mixture through flame holes of a ceramic plate, the transfer of heat to the body of a burner unit is reduced, thereby minimizing loss of heat.
