摘要:
This invention is an electricity generating organic light-emitting display device (OLED) consisting of vertically stacked layers including an organic light emitting device (OLED), an insulation layer, a solar cell and thin film transistors. The device can reduce the reflection of ambient light, improve the contrast of the signal, and enhance sun-light readability by allowing the ambient light to be absorbed by the solar cells. Furthermore, additional power will be generated by the solar cell through absorption of ambient light and backward emission of OLEDs. The device, without using the polarizer, can exhibit low reflectance characteristics over the visible region and high display contrast.
摘要:
A reconfigurable organic light-emitting device and a display apparatus employing the organic light-emitting device, wherein the reconfigurable organic light-emitting device includes at least two organic light-emitting layers and at least one high-energy-gap carrier-blocking layer. The at least one high-energy-gap carrier-blocking layer is formed between the organic light-emitting layers. The structure of the reconfigurable organic light-emitting device can be reconfigured through heating, and the reconfigurable organic light-emitting device may thus emit light characteristic of one layer of the at least two organic light-emitting layers, after a bias voltage is applied on the upper electrode and the lower electrode of the reconfigurable organic light-emitting device. The heating may be performed with a built-in resistive heating source, an external heating source or a light-beam. By employing the reconfigurable organic light-emitting device, a fixed-pattern, passive-matrix, or active-matrix display apparatus of multi-color or full-color may further be fabricated.

One embodiment relates to a computer-implemented process of content fingerprinting. A context and a content for fingerprinting are received. The context comprises a set of context components for use in generation of content fingerprints. The content includes instances of at least some of the context components. The content is processed to generate context offset sequences, and a fingerprint for the content is formed from at least a portion of the context offset sequences. Another embodiment relates to a computer-implemented process for comparing a target content against a pool of contents. The process includes constructing an automata data structure based on the fingerprints in the pool. Context offset sequences of a target fingerprint are scanned against the automata data structure to determine matched offset subsequences. Other embodiments, aspects and features are also disclosed.
