TOUCH SCREEN PANEL AND DISPLAY APPARATUS HAVING THE SAME

摘要

PURPOSE: A TSP(Touch Screen Panel) and a display device including the same are provided to improve the opening rate of the TSP by simplifying the construction of a driving unit in the TSP. CONSTITUTION: A unit pixel is connected to a gate line(GLN) and a data line(DLM), and a light sensing unit includes a first and a second switching device(T1,T2). The gate electrode of the first sensing switching device is connected to the gate line, and a drain electrode is connected to a lead-out line, and a source electrode is connected to a first node. When the first power is applied to the gate electrode of the second switching device, and the drain electrode of the second switching device is connected to the first node, and the source electrode is connected to the gate line. The second switching device is an oxide semiconductor thin film transistor, and the first power includes the first power includes a pulse signal.
