Title: Color display tube having internal magnetic shield
Inventor: HENDORITSUKU YAN DE UITO
IPC: H01J29/86
Filed: 1992-03-05
Abstract: PURPOSE: To provide a magnetic shield of a color display tube which sufficiently reduces an adverse effect upon color purity caused by the terrestrial magnetic field. CONSTITUTION: This color display tube includes a rectangular screen having a phosphor dotted pattern. In order to possibly reduce a mislanding error particularly in the Y axis direction of an electron beam, a means 20 for deflecting a magnetic line of force to a short side rather than a long side is provided in close proximity of an opening end 21 nearer to an electron gun of the color display tube. In particular, the short side has edges 22 and 23 extending toward the electron gun, or an edge strip band is removed from the long side, thereby constituting the means 20.

Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of gray scale reproducibility and the occurrence of uneven brightness in a liquid crystal device surface or the like due to veriation of panel temperature. SOLUTION: As for this liquid crystal device, in a liquid crystal panel P in which a pair of electrodes 3a, 3b are arranged so as to hold a liquid crystal 2 and one of the electrode 3b is connected to an active element 4, the temperature dependence of the voltage holding capacity between the pair of electrodes 3a, 3b is regulated to be <=10%/10 deg.C. Thus, even if the temperature of the liquid crystal panel P is locally varied by about 10 deg.C, the voltage effectively applied to the liquid crystal 2 is hardly changed, so that the lowering of gray scale reproducibility and the occurrence of uneven brightness in the liquid crystal device surface or the like are prevented.
