摘要:
A touch sensing device includes a touch screen including Tx lines, Rx lines crossing the Tx lines, and touch sensors formed between the Tx lines and the Rx lines, and a touch screen driving circuit which senses all the touch sensors of the touch screen in a first sensing step to detect the presence or absence of a touch input, and then again senses the touch sensors, in which the touch input is detected as a first sensing result, in a second sensing step to detect a position of the touch input. When there is no touch sensor, in which the touch input is detected as the first sensing result, the touch screen driving circuit repeats the first sensing step.
摘要:
Provided are a display having a touch sensor and a method for improving the touch performance thereof, which can minimize the distortion of an execution result induced by the process of converting the resolution of touch coordinates, by compensating the coordinate values of a touch position by applying different offset values for upper, lower, left, and right sides in accordance with the sensor data values of surrounding sensor nodes adjacent to a center node having peak data.

摘要:
The present invention discloses a defrost apparatus of a refrigerator which can defrost an evaporator by a defrost heater, when moisture of the ambient air of the evaporator is frozen on the surface of the evaporator. The defrost apparatus of the refrigerator includes a pair of evaporators and a pair of defrost heaters to selectively defrost the pair of evaporators. A path varying means for guiding air flow is installed near the pair of evaporators. The air is not supplied to the defrosted evaporator, for performing the defrosting operation. The air is supplied to the non-defrosted evaporator, for performing the cooling operation. As a result, the defrosting operation is efficiently performed, and the temperature does not sharply increase in freezing and refrigerating chambers, so that the food can be maintained fresh for an extended period of time.
