Abstract: An active matrix display device is disclosed. The display includes individual driver circuits for each pixel (100) to provide accurate, high resolution gray scale rendering and an almost 100 % duty cycle. The pixel circuit drivers (Figures 1(10), 2(20), 3(30), 4(40), 5(50), 6(60), 7(70) and 8(80)) minimize factors known to limit gray scale resolution, such as variations in threshold voltage, voltage drops in connecting lines and from leakage currents, and large peak currents. The present invention includes a line driver functioning initially as a low impedance voltage driver (Figure 6(60)), then converting to a high impedance current driver (Figure 6(60)). A method of driving a pixel (100) with sufficient circuitry to substain the pixel's light output at a gray level determined by the input data fed to the pixel (100) is also disclosed. The display is capable of processing both digital and anolog input data.

Abstract: A sealing structure (190) for an organic light emitting device display (100). The sealing structure (190) comprises a metal film (175) overlying a dielectric film (150). The sealing structure (190) has low moisture and oxygen permeability. At least one of the metal layers (175) may react with moisture or oxygen to seal off pin holes. A net low stress sealing structure (190) may be formed by combining tensile and compressive films. The sealing structure (190) may be etched to create openings (160) for connection to outside circuitry. The innovative sealing structure (190) minimizes moisture leakage and vertical shorts between diode cathode (900) and anode (400).

Abstract: A color organic light-emitting diode (OLED) display device is disclosed. The OLED display device comprises a silicon substrate (200) with a plurality of integrated OLED drivers (205) arranged in a matrix; a hydrophobic, transparent passivation layer (210); color filter or color changing media (230) patterned on the passivation layer (210); and a glass cover (220) for protecting the OLED drivers (205), passivation layer (210), and color filter or color changing media (230). The passivation layer (210) permits lithographic patterning of the color filter or color changing media (230) using wet processing methods. In an alternate embodiment, a getter layer (240) is formed on the substrate (200) and OLED drivers (205). The passivation layer (210) is then formed on the getter layer (240). A method for fabricating a color OLED display device with a passivation layer (210) and color filter or color changing media (230) is also disclosed.

Abstract: The invention is directed to an electrode structure (500) for an organic light-emitting device display (10). The electrode structure includes a transparent electrode (510) and a high conductivity rib (550). The structure (500) provides top side light output and a low line resistance, and enables a high resolution display. The structure permits a display to be built on top of a silicon driver chip for active matrix addressing.
