摘要: The present disclosure discloses a digital loop filter in an all-digital phase-locked loop. The digital loop filter may include a selection circuit configured to output one of a first data signal and a second data signal as valid data, a first operation circuit configured to output a first operation signal by adding or subtracting the valid data and a first register signal, a first register circuit configured to register the first operation signal and output the first operation signal as the first register signal, a second operation circuit configured to output a second operation signal by adding or subtracting a value of at least one bit of the valid data and the first register signal, and a second register circuit configured to store the second operation signal and output the second operation signal as a control signal.

摘要: 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.

摘要: 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.
