Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a movable portion, a fixed portion, and a driving assembly. The movable portion is used to connect the optical element. The movable portion may move relative to the fixed portion. The driving assembly is used to drive the movable portion to move relative to the fixed portion.

Abstract: An apertured shadow mask in a color cathode ray tube (CRT) serves as a color selection electrode in permitting each of the three electron beams to be incident only upon its associated color-producing phosphor elements on the CRT's display screen. The apertures are arranged in vertical columns and horizontal rows in the shadow mask with aperture spacing defined by a vertical pitch (P.sub.v) i.e., the vertical spacing between adjacent apertures within the same vertical column where the apertures in one row are in different columns than the apertures in adjacent rows, and a horizontal pitch (P.sub.h), i.e., the horizontal spacing between adjacent apertures in the same horizontal row. To increase the color purity adjustment margin particularly in the corners of the display screen while still maintaining sufficient vertical spacing between adjacent phosphor dot color trios for a high degree of video image resolution, P.sub.
