    摘要： The present disclosure relates to an X-ray detector. The X-ray detector includes the first and second gate lines arranged to be spaced apart from each other on a substrate, a data line and a bias line that are arranged to be spaced apart from each other in a direction intersecting the first and second gate lines, and define a unit pixel area, a storage capacitor that is arranged in the unit pixel area and has one end connected to a ground, a phototransistor that is turned on by a reset signal applied to the first gate line and provides a signal generated by an incident light source to the storage capacitor, and a thin film transistor that is turned on by a gate signal applied to the second gate line to provide a charge stored in the storage capacitor to the data line.

    摘要： According to an aspect of the present disclosure, an organic light emitting display device includes a plurality of pixels each including a pixel driving circuit. The plurality of pixels includes an organic light emitting diode and a driving TFT configured to control driving of the organic light emitting diode and including a gate node as a first node, a source node as a second node, and a drain node. Also, the plurality of pixels includes first to third switching TFTs electrically connected to the driving TFT and first and second storage capacitors configured to store a voltage to be applied to the driving TFT DT. Further, the plurality of pixels includes a coupling capacitor connected to a gate node of the third switching TFT so as to increase a voltage to be applied to the gate node of the driving TFT.
