PLEDs use semiconducting polymers that emit light when electric current is applied. They provide more efficient LED displays than traditional LEDs, and are useful for portable device displays due to their flexibility and thinness. PLEDs have an anode, cathode, and polymer film sandwiched between them. When voltage is applied, the polymer emits light. PLEDs can be flexible, transparent, or stacked to provide different display types and colors. They have advantages over LCDs like lower power use and wider viewing angles, but shorter lifetimes. PLEDs are being developed for applications like phones, watches, TVs, and more.
Light emitting polymers (LEPs) were discovered in 1990 and provide benefits over other displays like LCDs. LEPs use a semiconducting polymer sandwiched between electrodes that emits light when electrons and holes recombine upon application of a voltage. Cambridge Display Technology is developing LEP displays that combine characteristics of CRTs and LCDs with benefits of formability and low power. LEPs are manufactured using spin coating or printer-based techniques like inkjet printing to apply the polymer in thin layers, then electrodes are added to create the final display.
This presentation is about the next Gen display technology Light emitting polymer. It overcomes the disadvantages of LCD's and LED's and take you to to the next level of enjoying this technology.
Light emitting polymers (LEPs) emit light when an electric field is applied. LEPs consist of a thin film of polymer sandwiched between an anode and cathode. When a voltage is applied, electrons are injected from the cathode and holes from the anode, which recombine and emit light radiatively. LEPs have advantages such as low energy consumption, suitability for large area lighting, simple fabrication process, and potential for flexible displays.
This document discusses flexible electronic displays and organic light emitting diode (OLED) technology. It begins with acknowledgements and outlines the aims and structure of the project. It then discusses what makes flexible displays attractive, describing them as rugged, lightweight, thin, portable and low power. It explains that flexible displays are either reflective like e-paper or emissive like OLEDs. Key types of reflective displays discussed are Gyricon, electrophoretic ink and cholesteric, while OLED displays are described as self-emissive. Advantages of flexible OLEDs include being thinner, lighter, flexible and requiring less power than other display technologies.
This document provides an overview of light emitting polymers (LEP) including:
1. LEPs emit light through electroluminescence and are made from semiconducting polymers sandwiched between an anode and cathode.
2. LEP displays use a matrix of pixels that are individually controlled to emit different colors and intensities of light.
3. LEPs have advantages over LCDs like lower power consumption, better viewing angles, and the ability to be made on flexible substrates. However, they also have limitations like degradation over time.
4. LEPs have applications in displays for devices like phones, watches, signs, and vehicles and their use is expected to
OLED (Organic Light Emitting Diode) is a light emitting diode with an electroluminescent layer made of organic compounds that emit light in response to an electric current. OLEDs were first developed in the 1950s and have several advantages over LCDs like being thinner, more flexible, and requiring less energy. Key applications today include TVs, phones, watches, and more. Research is ongoing to improve OLED efficiency and lifespan for broader adoption.

The document discusses optimizing images for better web performance. It introduces Shogo Sensui and his work optimizing images at CyberAgent. It then discusses factors that impact web performance like minimizing payload size and optimizing rendering. It demonstrates how tools like ImageOptim, ImageAlpha, and JPEGmini can optimize images, significantly reducing file sizes in some cases. Shogo Sensui created grunt-image and gulp-image tools to optimize images from the command line. The conclusion recommends using different image formats like 24-bit PNG, JPEG, and 8-bit PNG for different image types and stages of a website project.
