Latest Patents
Roush's latest patents focus on an improved active matrix organic light-emitting diode (AM OLED) pixel circuit and a method of wide dynamic range dimming for AM OLED displays. These innovations maintain color balance throughout the dimming range and ensure uniformity of luminance and chromaticity at low gray levels. This is particularly important for avionics, cockpit, and hand-held military device display applications. The disclosed OLED pixel circuit utilizes Pulse Width Modulation (PWM) of the OLED pixel current to achieve the desired display luminance. Two example circuits modulate the common cathode voltage or common power supply voltage to adjust the OLED current. Additionally, three example circuits incorporate extra transistor switches in the pixel circuit to modulate the OLED current during the frame time. This combination allows for wide dynamic range dimming while maintaining the necessary color balance and uniformity across the display surface.
