  • Publication number: 20190285942
    Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a backlight unit. The backlight unit may include a printed circuit board, a plurality of light-emitting diodes mounted on the printed circuit board, at least one light spreading layer formed over the printed circuit board that spreads light received from the plurality of light-emitting diodes, a partially reflective layer formed over the at least one light spreading layer, a color conversion layer formed over the partially reflective layer, a collimating layer formed over the color conversion layer, a brightness enhancement film formed over the collimating layer, and a diffuser formed over the brightness enhancement film. The at least one light spreading layer may include two light spreading layers with elongated protrusions that are rotated relative to each other.

  • Patent number: 8663155
    Abstract: A device (12) and method are provided for percutaneous transdermal delivery of a potent pharmacologically active agent. The agent is dissolved in water to form an aqueous coating solution having an appropriate viscosity for coating extremely tiny skin piercing elements (10). The coating solution is applied to the skin piercing elements (10) using known coating techniques and then dried. The device (12) is applied to the skin of a living animal (e.g., a human), causing the microprotrusions (10) to pierce the stratum corneum and deliver a therapeutically effect dose of the agent to the animal.

  • Patent number: 7438926
    Abstract: This invention relates to a method for inhibiting a decrease in the transdermal flux of an agent that is being transdermally delivered or sampled over a prolonged period of time wherein the delivery or sampling involves disrupting at least the stratum corneum layer of the skin to form pathways through which the agent passes. The desired result is achieved by co-delivering or co-sampling the agent with an amount of at least one anti-healing agent wherein the amount of the anti-healing agent is effective in inhibiting a decrease in the agent transdermal flux compared to when the delivery or sampling of the agent is done under substantially identical conditions except in the absence of the anti-healing agent(s).

  • Patent number: 7087035
    Abstract: A device and method for enhancing skin piercing by microprotrusions involves pre-stretching the skin to enhance pathway formation when the microprotrusions are pressed into the skin. An expandable device includes skin engaging opposite ends that contact the skin surface so that when the device is expanded the skin is stretched. The skin is placed under a tension of about 0.01 to about 10 megapascals, preferably about 0.05 to 2 megapascals. The device has a plurality of microprotrusions which penetrate the skin while the skin is being stretched by the expanded device. Another stretching device employs suction for skin stretching.

  • Patent number: 6562014
    Abstract: A transdermal agent sampling device is provided. The sampling device is comprised of a microblade array and a device for applying a partial vacuum. The microblade array comprises a sheet having a plurality of microblades for piercing the skin to a very shallow depth (i.e., 25 &mgr;m to 400 &mgr;m) to create microslits in the outermost stratum corneum layer of the skin. The partial vacuum applying device applies a partial vacuum in the range of about 0.1 to about 0.8 atm, and preferably about 0.3 to about 0.7 atm, for sampling a body analyte such as glucose in interstitial fluid. The partial vacuum is applied for a period of about 2 to about 30 seconds, and preferably about 5 to about 15 seconds. The interstial fluid is analyzed for body analyte (e.g., glucose) content or concentration.
