  • Patent number: 10929634
    Abstract: An operating method of a touch sensor includes sensing first touch intensities in a first touch-sensing area by using first touch cells, sensing second touch intensities in a second touch-sensing area that is adjacent to the first touch-sensing area by using second touch cells each having an area that is smaller than that of each of the first touch cells, grouping some second touch cells among the second touch cells as a touch-sensing group having a same area as one of the first touch cells, calculating a representative touch intensity of the touch-sensing group by using the second touch intensities sensed by second touch cells in the touch-sensing group, and detecting a touch position by using the first touch intensities and the representative touch intensity.

  • Patent number: 10488684
    Abstract: A display apparatus includes a display panel and a display panel driver. The display panel includes a lower substrate and an upper substrate facing the lower substrate. The lower substrate includes a first base substrate and a flexible substrate. The flexible substrate has an area larger than an area of the first base substrate. The display panel driver includes a gate driver configured to apply a gate signal to a gate line of the display panel and a data driver configured to apply a data voltage to a data line of the display panel.

  • Publication number: 20190070336
    Abstract: The present invention relates to a method for preparing a biocompatible porcine cartilage-derived extracellular matrix membrane capable of adjusting an in-vovo degradation rate and a mechanical property, and a composition containing the porcine cartilage-derived extracellular matrix as an active ingredient, for preventing adhesion between tissues and/or organs. Despite its high biocompatibility as a natural material, cartilage tissue extracellular matrix has a short decomposition period and its mechanical property is weak, thereby restricting the application. Accordingly, a method of enhancing the mechanical property through physical or chemical treatment and radiation treatment has been developed. In the present invention, biomaterials of various formulations were produced by treating the porcine cartilage-derived extracellular matrix with physiochemical methods.

  • Patent number: 8970570
    Abstract: A display device includes a display panel configured to receive a first-frame image signal for displaying a first-frame image in a first frame. The display panel is further configured to receive a second-frame image signal for displaying a second-frame image in a second frame that immediately follows the first frame such that the display panel appears to display a transition region associated with a boundary between a portion of the first-frame image and a portion of the second-frame image and moving in a moving direction. The display device further includes an optical effect layer and electrode sets. The electrode sets respectively overlap different portions of the optical effect layer and are configured for sequentially starting affecting the different portions of the optical effect layer such that the optical effect layer appears to display a light-blocking section that moves in the moving direction and overlaps the transition region.
