PURPOSE:To expose a fluorescent screen with the same exposure device regardless of the arrangement of a digitally arrayed electron gun by matching a thinner wedged lens with the direction of the deaxialized length S in the digitally arrayed electron gun and exposing with a digitally arrayed light source. CONSTITUTION:Since the DELTAP' component of the landing error is an error which is commonly generated in tri-colors, it can be compensated with an optical lens. On the other hand, since the beam deflection compensation DELTAS' differs from each direction S of blue B, red R, and green G, it must be compensated using a wedged lens. Consequently, the fluorescent screen is exposed and sticked using a digitally arrayed light source, it is exposed, matching the thinner wedged lens with direction of the deaxialized length S in the digitally arrayed electron gun. By combining an electron gun with inline arrays with this fluorescent screen 2, a picture tube is completed. This reduces the necessary beam compensation and controls the generation of a color shift. |
