Abstract: A home port for a semiconductor manufacturing nozzle head includes a body having a discharge space configured to receive treatment liquid discharged from a plurality of nozzles, discharge flow passages connected to be in communication with the discharge space and penetrating through the body so as to face the plurality of nozzles, and a cleaning liquid distribution system, which is formed to penetrate through the body, and is connected to transfer a cleaning liquid to the discharge flow passages. The cleaning liquid distribution system includes supply flow passages connected to supply the cleaning liquid to the discharge flow passages, and a lead-in passage connected to and which joins the supply flow passages, and connected to receive the cleaning liquid injected from the outside.

Abstract: Disclosed is an organic light emitting display device. The organic light emitting display device includes a display panel including a plurality of pixels formed in intersection areas between a plurality of gate lines, a plurality of data lines, and a plurality of sensing lines, a gate driver supplying a gate signal to the gate lines, a plurality of data driving ICs including a data driver, supplying data voltages to the data lines, and a sensing unit including a plurality of ADCs that each sense characteristic change of a driving transistor included in a corresponding pixel to generate sensing data, a memory storing a gain error and offset error of each ADC, and a timing controller correcting the sensing data on a basis of the gain error and offset error, modulating input data on a basis of the corrected sensing data, and supplying the modulated data to the data driving ICs.
