Transflective display panel and display apparatus using the same

InactiveUS20080158486A1High-brightness color reproductionHigh reflective brightnessNon-linear opticsTransmittanceLiquid crystal
A transflective display panel and a display apparatus using the same are provided. The display panel includes a plurality of pixels arranged in a matrix. Each of the pixels includes a plurality of subpixels, and each subpixel within a pixel outputs a different color of light. In addition, each of the subpixels includes a transflective mode region which has a reflection mode region with a diffraction grating and a transmission mode region; a liquid crystal layer which adjusts a transmittance of incident light through electric control; and a sub color filter which transmits light within a wavelength band of the incident light. Because the display panel includes the reflection mode region where the diffraction grating is formed, it can display a high-quality image with good white balance, even while outdoors or under bright illumination.

Image feature extraction device

This image feature extraction device extracts, from an image, an image feature that makes it possible to adjust the balance between identification capability and robustness, which are the scales of the capability of determining identity of images. This image feature extraction device executes hierarchical quantization to calculate quantization indexes of a plurality of hierarchies in accordance with a previously defined hierarchical quantization method for each quantization target region of an image, and outputs a hierarchical quantization index code, which is an encoding allowing unique specification of the quantization indexes of the respective hierarchies of each quantization target region.
