摘要:
An organic light-emitting device includes a first electrode, a second electrode, and a light-emitting layer disposed between the first and second electrodes. The light-emitting layer contains an organic compound emitting photoluminescent light with a peak wavelength of 430 to 480 nm. The organic compound has a profile factor of 0.02 or less at a wave number of 1,300 to 1,680 cm -1 as calculated from Huang-Rhys factors.

摘要:
The present invention provides a threshold matrix that can obtain high-quality images with a uniform dot distribution using small masks and that can obviate the need to increase the mask size for a high-definition printer to reduce the memory capacity required to store the masks, as well as a gray-level reproduction method and apparatus using this threshold matrix. A threshold matrix is formed so that (1) a dot pattern generated by executing gray level processing using the threshold matrix has a set of element pixel blocks having in all gray levels the same dot distribution in each element pixel block corresponding to each element mask, so that (2) a low irregularity or pseudo periodicity is introduced into one of the low gray levels after the first gray level, so that (3) in all gray levels, the number of dots is equal for all element pixel blocks, and so that (4) every 4n ((n) is an integer) gray levels, the number of dots is equal for four partial element pixel blocks each obtained by dividing each element pixel block into four.
