  • Publication number: 20120092302
    Abstract: It is an object of the present invention to provide a display device equipped with a display panel that is provided with a photo-detection section with improved accuracy of detecting a touch position. A display panel (11) of an organic EL display device (10) includes a photo-detection section (40) that detects reflected light when a screen is touched by a finger or the like. The photo-detection section (40) includes a photodiode (41) that receives the reflected light, and an output amplifier (42) that outputs an output voltage corresponding to the amount of the received light. If an a-Si diode is used for such a photodiode (41), a sufficiently large signal difference in sensitivity between the bright state and the dark state can be achieved. Also, if a p-Si amplifier is used for the output amplifier (42), the output voltage becomes the saturation voltage at the time of read-out.

  • Publication number: 20110050759
    Abstract: In a display device driven by multi-picture element driving, in order to realize narrowing of a frame, a gate driver provided in the display device includes buffers. Storage capacitor driving signals are inputted in the buffers. In at least one embodiment, once the storage capacitor driving signals are inputted, the buffers shape waveforms of the storage capacitor driving signals, and outputs the storage capacitor driving signals thus shaped to storage capacitor wires via terminals “CSVtypeA1?R” to “CSVtypeA4?R” and terminals “CSVtypeA1?L” to “CSVtypeA4?L”. The buffers supply storage capacitor driving signals reduced in waveform rounding as such, to drive a storage capacitor that is connected to the storage capacitor wires.
