  • Patent number: 9748321
    Abstract: An organic light-emitting diode display is disclosed. In one aspect, the display includes a substrate that includes a first sub-pixel region and a second sub-pixel region adjacent to the first sub-pixel region, and a first driving circuit and a second driving circuit respectively disposed in the first sub-pixel region and the second sub-pixel region. The first and second driving circuits include a first thin film transistor (TFT) and a second TFT. The display further includes a first pixel electrode and a second pixel electrode electrically connected to the first driving circuit and the second driving circuit, respectively, and a common electrode facing the first and second pixel electrodes. A first organic emission layer is interposed between the first pixel electrode and the common electrode, and a second organic emission layer interposed between the second pixel electrode and the common electrode, and a light-shielding member is configured to shield incident light.

  • Publication number: 20160189609
    Abstract: An organic light emitting display apparatus includes first and second pixels on a display region, first and second scan lines connected to the first and second pixels respectively, and a gate driver to output a first scan signal and a second scan signal to the first and second scan lines respectively. The first pixel includes a first pixel circuit and a first organic light emitting diode (OLED). The second pixel includes a second pixel circuit and a second OLED. Each of the first and second pixel circuits includes a driving transistor to output driving current to the anode of a respective one of the first and second OLEDs. The anode of the second OLED at least partially overlaps the gate of a driving transistor of the first pixel circuit.

  • Publication number: 20040188964
    Abstract: A novel two wheel-hand truck for easy, semi-automatic, loading and unloading, is equipped with a means, which is installed in the platform of the hand-truck, including but not limited to, double layers, upper and lower layer, of staggered rollers in the platform, a synthetic rubber belt optionally surrounding the upper layer rollers to fill the clearances, and two wheels. The rollers are constructed of cast iron having outer diameter of 3 to 30 mm. Diameter of all the rollers of the upper layer and the lower layer may be the same. More than one row of the double layers may be installed in row in a platform. The front edge of the platform is tapered for easy access of the bottom of the luggage to be loaded.

  • Publication number: 20040129744
    Abstract: A novel folding and expanding hanger for narrow neck top wears is comprised of, including but not limited to, a spring, two solid wings, a pivot pin, a hook, and a member connecting the hook and pivot pin. The spring, coiled around at the center of the pivot pin, renders a repulsion force for thrusting the wings to the extended position. The two solid wings are firmly connected to the arms of the spring. The pivot pin is pivotably connected to one end of the two wings. The hook, which has distorted neck, is connected to a member, which has two hands anchored to the pivot pin at both sides of the spring. The hook may be connected directly to a spring, which has two extended wings of 5 to 20 cm long. The other ends of the two wings may be broader than the opposite ends for sustaining the shape of the top wears.
