  • Method of producing a flat LED panel display
    Patent number: 4775645
    Abstract: A flat LED panel display with LED elements arranged in a high density and a method of producing such a display are disclosed. A conductive layer is deposited on a ceramic substrate and bonded to one surface of an LED wafer by a conductive paste. A plurality of electrodes are arranged on the other surface of the LED wafer in rows and columns to define a two-dimensional pattern. Slits are formed along the rows or the columns each to a depth which extends from the other surface of the LED wafer to the ceramic substrate. Other slits are formed perpendicular to the first-mentioned slits each with a depth which extends from the other surface of the LED wafer to a position deeper than it but short of the ceramic substrate.
