  • Patent number: 9030460
    Abstract: A display apparatus includes pixels, a driver for providing a driving voltage, and conductive lines including a first line, a second line, and a third line. The display apparatus further includes a first circuit electrically connected to the driver for receiving the driving voltage and electrically connected to the pixels for controlling the pixels. The first circuit includes a first chip, a first inner line, a first pad, a second pad, a third pad, a fourth pad, and a fifth pad. The first chip is electrically connected to the driver through the third pad, the fourth pad, the fifth pad, the third line, the second line, the second pad, the first inner line, the first pad, and the first line. The fourth and fifth pads may contribute to consistent resistance for paths that transmit the driving voltage, for enabling desirable display quality of the display apparatus.

  • Patent number: 8976305
    Abstract: A display apparatus includes a light generating part and a display panel. The display panel includes a first substrate, and a second substrate facing the first substrate. The second substrate includes a plurality of pixel units including a sensor sensing the light generated from the light generating part and reflected from an object disposed on the display panel, and a pixel. The display panel further includes a light blocking member which is positioned at a position corresponding to an area in which the sensor is disposed and prevents the light generated from the light generating part from being directly incident to the sensor. The light blocking member is disposed on the first substrate.
