  • LED display apparatus having active devices and fabrication method thereof
    Patent number: 9111843
    Abstract: An active matrix LED display apparatus and a fabrication method thereof are provided. The active matrix LED display apparatus enables to miniaturize pixel by a formation of wiring on bottom layer and an assembly of each block through each eutectic layer into each transistor block receptor and/or each LED block receptor formed according to each color element unit, and to be embodied with high luminance, low power consumption, high reliability and superior optical property by assembling a transistor block having high electron mobility. And the fabricating method of the present invention enables to make efficiently an AM-LED display apparatus at room temperature in a short time by using different shapes of receptor and block depending on the function of a transistor and/or on the color of an LED.
    Type: Grant
