  • Patent number: 11817058
    Abstract: A light emitting display device includes a display panel configured to display an image, a data driver configured to supply a data voltage to data lines of the display panel, and a sensing circuit configured to obtain a sensing voltage through sensing lines of the display panel after reflecting a negative impedance value canceling impedance differences of the sensing lines.

  • Patent number: 11670223
    Abstract: An electroluminescent display device includes a display panel including a plurality of pixels connected to a plurality of sensing lines, a plurality of sampling circuits configured to simultaneously sample driving characteristics of the pixels to generate sampling outputs, a plurality of sampling multiplexers configured to divide the sampling outputs into n groups and to alternately select group sampling outputs, a plurality of scalers individually connected to the sampling multiplexers, and a global multiplexer configured to selectively connect outputs of the scalers to an analog-to-digital conversion circuit, wherein the number of scalers is less than the number of sampling circuits.

  • Publication number: 20220334130
    Abstract: The present invention relates to a melanogenesis detection method using FAM86A, and the like. The level of FAM86A of the present invention decreases according to an increase in the amount of melanin secretion or formation, and thus the present invention can whiten the skin by using protein FAM86A or an agonist thereof, and can prevent, treat or alleviate melanin-deficiency diseases such as vitiligo since the formation and secretion of melanin is promoted when FAM86A is inhibited. Therefore, the present invention is expected to be used in various ways, such as a composition for skin whitening using protein FAM86A or an agonist thereof, and as a composition for preventing and treating melanin deficiency diseases including vitiligo and canities by using a FAM86A inhibitor.
