An improved AM OLED pixel circuit and method of wide dynamic range dimming for AM OLED displays are disclosed that maintain color balance throughout the dimming range, and also maintain the uniformity of the luminance and chromaticity of the display at low gray-levels as the display is dimmed to lower luminance values. As such, AM OLED displays can meet the stringent color / dimming specifications required for existing and future avionics, cockpit, and hand-held military device display applications. Essentially, the OLED pixel circuit and method of dimming that are disclosed use Pulse Width Modulation (PWM) of the OLED pixel current to achieve the desired display luminance. Two example circuits are disclosed that externally PW modulate the common cathode voltage or common power supply voltage to modulate the OLED current in order to achieve the desired display luminance. Three example circuits are disclosed that incorporate additional transistor switches in the pixel circuit to modulate the OLED current during the frame time. By PWM of the OLED current, in combination with data voltage (or current) modulation, wide dynamic range dimming can be achieved while maintaining the color balance and the luminance and chromaticity uniformity required over the surface of the display involved.

Milled, small particle size, solid bicyclo[2.2.1]heptane dicarboxylate salt-containing thermoplastic nucleating additive formulations further comprising at least one anticaking agent for improved haze reduction, improved nucleation performance, and prevention of potential cementation (via agglomeration) of the salt component present therein are provided. Such small particle size dicarboxylate salts provide desirable properties within thermoplastic articles, particularly as nucleating agents, but apparently suffer from certain clarity issues and agglomeration problems (due to the flat and thin plate structures of such compounds and the propensity they exhibit to cohere to each other during storage), making utilization thereof less desirable for certain applications. Thus, an improvement has been provided to permit full benefit of the excellent crystallization temperatures, stiffness, and calcium stearate compatibility such dicarboxylate salts accord within target low haze thermoplastics. Furthermore, unexpected improvements in dusting reduction have been found upon the utilization of such anticaking additives in combination with the aforementioned nucleating salts. Thermoplastic additive compositions and methods of producing thermoplastics with such nucleator / anticaking additive combinations are also contemplated within this invention.

A button head tie has a button head and a tie strap. The button head is a generally flat member having an aperture for receiving the tie strap. The aperture includes lead-in ramps to facilitate tie strap insertion and is configured to prevent angled tie strap insertion. The tie strap is a flat elongate member having a wedge that is captured within the aperture. The remainder of the strap passes through the aperture. The wedge and strap have teeth and serrations on both sides, respectively, the teeth and serrations being engageable. In use, the strap is looped around a bundle and inserted into the aperture to either side of the wedge. Strap insertion force is reduced by standoff tabs which elevate the wedge out of aperture, temporarily, during installation. When loop tension is applied to the bundle, the wedge is pulled into the aperture, compressively locking the strap.

A smoking article having one or more reconstituted tobacco split inner wrap strips is described. One or more split inner wrap strips extend coaxially along the tobacco column between the inner surface of an outer wrap of cigarette paper and the tobacco column. The tobacco blend includes burley and a second tobacco, such as flue-cured, oriental, Maryland, or rare and exotic tobaccos, and combinations thereof This blend improves burley smoke character without increasing Hoffman analyte levels, especially tobacco-specific nitrosamines (i.e., TNSAs). A cigarette with an improved burley smoke character without increasing Hoffman analyte levels is also described.
