  • Patent number: 12232405
    Abstract: A display device includes a display module and a flexible circuit film connected to the display module. The display module includes a display panel and an input sensing layer. The flexible circuit film includes a base film, a ground line disposed on the base film, a plurality of connection lines disposed on the base film and electrically connected to at least one of the input sensing layer and the display panel, a conductive layer disposed on the connection lines and overlapping at least a portion of the connection lines, an insulating layer disposed on the conductive layer, and a cover tape disposed on the insulating layer and overlapping the ground line.

  • Patent number: 12039904
    Abstract: A noise measurement device for measuring noise of a test image displayed on a display device including a display panel and an input sensor configured to sense an external input, includes a luminance meter, a converter, and a determiner. The luminance meter is configured to: measure a luminance of the test image in a state in which the input sensor is turned on to generate first luminance measurement values; and measure a luminance of the test image in a state in which the input sensor is turned off to generate second luminance measurement values. The converter is configured to apply a contrast sensitivity function to luminance difference values between the first and second luminance measurement values to generate final conversion values. The determiner is configured to compare the final conversion values with a predetermined reference range to determine whether a defect exists in the test image.
