Abstract: Disclosed is a method of detecting touch coordinates in a touch sensing device. The method of detecting touch coordinates may include calculating touch coordinates of a touch point, determining whether the touch coordinates need to be corrected, extending a first distance between reference coordinates and the touch coordinates to a second distance when the touch coordinates need to be corrected, and correcting the touch coordinates by using a value of the second distance.

Abstract: Disclosed are a device and method for measuring an organic light emitting diode, which measures an amount of energy for compensating for a burn-in of an organic light emitting diode, by sensing a charged voltage of a sensing line connected to the organic light emitting diode. The device for measuring an organic light emitting diode includes an external current source, and is configured to measure an amount of energy for compensating for a burn-in, by sensing a charged voltage of a parasitic capacitor of a sensing line.

Abstract: Disclosed are a communication method between a master controller and slave controllers, a slave controller for the communication method, and a battery management system using the communication method and the slave controller, in which the master controller receives safety information about battery cells through a plurality of channels even when each of a plurality of slave controllers includes only one micro controller unit, thereby minimizing the increase in the cost and enhancing the safety of the battery management system. The communication method includes performing bidirectional communication between a master controller and first to Nth (where N is an integer equal to or more than two) slave controllers through a first communication channel, and receiving, by the master controller, an indication signal through a second communication signal via the first to Nth slave controllers.
