Abstract: The present invention relates to a photoresist stripper composition for manufacturing a display, and more particularly, to an integrated photoresist stripper composition which can be used in every process for manufacturing a display. More specifically, the photoresist stripper composition for manufacturing a display according to the present invention can be applied to all of transition metals and oxide semiconductor wirings, and has an excellent ability to remove modified photoresist after a hard bake process, and implant process, and a dry etch process have been performed. In particular, the photoresist stripper composition for manufacturing a display according to the present invention exhibits a corrosion inhibitory effect that has been further specialized for copper (Cu) wiring pattern edge portions which are susceptible to corrosion following dry-etching.

Abstract: A method of correcting an output value of a geomagnetic sensor that recursively calculates a state estimate, an estimate gain vector, and an estimate error co-variance based on the output value of the geomagnetic sensor that is acquired sequentially and corrects the output value of the geomagnetic sensor based on the value includes acquiring a kth output value of the geomagnetic sensor, calculating a kth estimate gain vector based on a k?1th estimate error co-variance and the kth output value, calculating a kth state estimate based on the calculated kth estimate gain vector and the kth output value and a k?1th state estimate, calculating the kth estimate error co-variance using the kth estimate gain vector and a k?1th estimate error co-variance, and correcting the output value of the geomagnetic sensor based on the kth state estimate, wherein k is a natural number larger than 1.

Abstract: A method for calculating an angle of inclination of a magnetic field in a sensor coordination system includes measuring a magnetic field vector using a magnetometer, measuring an acceleration vector using an accelerometer, determining whether the sensor coordination system is in a moving state or a stationary state using the acceleration vector, and calculating the inclination angle of the magnetic field using the magnetic field vector and the acceleration vector, in response to the determining indicating the stationary state.
