摘要:
In an image display apparatus which has a multi-electron beam source in which a plurality of electron emission elements are connected in a matrix pattern using a plurality of data electrodes and a plurality of scanning electrodes, and a fluorescent screen having phosphors of three primary colors R, G, and B corresponding to the electron emission elements, natural white color emission is obtained while suppressing a decrease in G luminance, using, e.g., a checkerboard layout which has a G spatial resolution higher than the R or B spatial resolution and includes more G phosphors than the R or B phosphors. For this purpose, the scanning electrodes connected to the electron emission elements corresponding to the G phosphors are electrically independent from those connected to the electron emission elements corresponding to the R or B phosphors, signal components corresponding to the G phosphors and signal components corresponding to the R or B phosphors are extracted from an image signal for a 1-line period, and the scanning electrode connected to the electron emission elements corresponding to the G phosphors and those connected to the electron emission elements corresponding to the R or B phosphors are selected during successively the 1-line period.
摘要:
A method and apparatus for detecting the relative positional displacement between a mask and a wafer. The mask is provided with a cantilever. The position mark is provided on the wafer so as to face the cantilever. A relative positional displacement between the mask and the wafer is detected from a deformation amount of the cantilever based on a force acting between the position mark and the cantilever upon relative movement of the position mark and the cantilever.
