  • ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE AND METHOD OF MANUFACTURING AN ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE
    Publication number: 20200052056
    Abstract: An organic light emitting diode display device includes a substrate, a first oxide transistor, a second oxide transistor, and a sub-pixel structure. The substrate has a display region including a plurality of sub-pixel regions and a peripheral region located in a side of the display region. The first oxide transistor is disposed in the peripheral region on the substrate, and includes a first oxide semiconductor pattern that includes tin (Sn). The second oxide transistor is disposed in the sub-pixel regions each on the substrate, and includes a second oxide semiconductor pattern. The sub-pixel structure is disposed on the second oxide transistor.

  • Photo sensor-integrated tubular light emitting apparatus and lighting system using the same
    Patent number: 9468066
    Abstract: A photo sensor-integrated tubular light emitting apparatus includes a cylindrical cover unit, a light-emitting module and a pair of sockets. The cylindrical cover unit includes a heat dissipation member and a cover. The cover has light-transmittance and is combined with the heat dissipation member. The light-emitting module is disposed in the cylindrical cover unit and has a plurality of arrayed light-emitting devices therein. The pair of sockets is combined with ends of the cylindrical cover unit. A photo sensor module is disposed in one of the pair of sockets. A driving voltage applied to the light-emitting module is adjusted based on an amount of light sensed by the photo sensor module.
