  • Patent number: 11810502
    Abstract: An electroluminescent display apparatus including a pixel connected to a detection line; a panel driving circuit configured to off-drive a driving element included in the pixel in a detection interval; a reference voltage generating circuit configured to supply a detection reference voltage to the detection line prior to the detection interval, generate a first comparator reference voltage which is higher than the detection reference voltage in the detection interval, and generate a second comparator reference voltage which is lower than the detection reference voltage in the detection interval; a comparator configured to compare the first comparator reference voltage with a voltage of the detection line to generate a first comparison output at a first timing of the detection interval and comparing the second comparator reference voltage with the voltage of the detection line to generate a second comparison output at a second timing of the detection interval; and a logic circuit configured to determine an occ

  • Patent number: 11804157
    Abstract: An electroluminescent display apparatus can include a display panel including the one or more subpixels connected to a data line, a gate line, and a low-level power line. The display apparatus can further include a comparator connected to the one or more subpixels through the data line and the low-level power line to compare a first input voltage from the data line with a second input voltage from the low-level power line to generate a comparison output. The first input voltage is a reference voltage, and the second input voltage is a voltage of a specific node of the one or more subpixels capable of being shifted from an initialization voltage.
