摘要： PURPOSE:To prevent circuit breakdown and picture quality deterioration by providing a conductor, insulated from a phosphor screen at the front case, in circumferential shape at the inner face of the standing-up part of a front case, and connecting the conductor to an external terminal. CONSTITUTION:The front case 1 made of glass is provided with a phosphor screen 5 at the inner face of that transparent part. Also, at the inner face of the standing-up part of the front case 1 is provided in circumferential shape a conductor 4 insulated from the phosphor screen 5, and the terminal 6 of the conductor 4 is connected with outside. When high voltage applied to the phosphor screen 5 leaks, the probability of flying to the nearest conductor 4 is high, and creeping leakage at the exposed part of the inner face of the front case 1 or discharge by partial charge-up also probably flies to the conductor 4 whereby high voltage is stabilized. In this way, it can prevent circuit breakdown caused by direct flying to an electron beam control means 3, or picture quality deterioration caused by magnetization of the electron beam control means 3.

摘要： PURPOSE:To enhance the horizontal resolution as a frame screen by shifting the phase in horizontal orientation of each line of phosphor constituting a scanning line corresponding to respective field in an amount 1/2 trio from one another between fields. CONSTITUTION:Three-color phosphor lines 1P, 2P, 3P,... in the horizontal direction are cones for scanning lines to constitute the P field, while phosphor lines 1S, 2S, 3S,... adjoining to the phosphor lines 1P, 2P, 3P,... constituting the P field are ones for scanning lines to constitute the S field. The lines 1S, 2S, 3S,... are coated being shifted from the lines 1P, 2P, 3P,... in an amount 1/2 trio pitch in the horizontal direction. Thereby two field screens compensate each other, and a screen is obtained which excels in the horizontal resolution as frame screen.

摘要： PURPOSE:To prevent a screen quality from being deteriorated by providing a container with holes and positioning/fixing an electron beam controlling means through these holes against a phosphor screen disposed on the container. CONSTITUTION:One of containers 1a and 1b divided in two is provided with holes 4. An electrode composite (an electron beam controlling means) 3 disposed inside this container 1a is positioned/fixed through the holes 4 against the one container 1a coated with a phosphor screen 2, and next the holes 4 are sealed. Accordingly, positioning of the phosphor screen 2 to the electrode composite 3 is performed with good precision because they have no effect of a positioning shift due to heat generated when the containers 1a and 1b are stuck to each other by firing. Hence, screen quality can be improved.

摘要： PURPOSE:To reduce the color phase irregularity at the horizontal ends of a screen, by making an electron beam acceleration electrode of a flat plate and providing the electrode with holes corresponding to the positions of passage of electron beams, and by attaching the electrode with horizontal support plates to the fluorescent screen. CONSTITUTION:In an image display device, a plurality of cathodes and a plurality of flat electrodes are disposed between a rear electrode and a screen and sealed in a glass container. An electron beam acceleration electrode block, which is provided between a horizontal convergence electrode 6a and a fluorescent surface 9, is constructed so that an acceleration electrode 23 made of a flat plate and having the same number of holes as the horizontal convergence electrode 6a is welded to a frame 25 and attached to the fluorescent surface 9 through support plates 24 welded to the lateral portions of the electrode 23 and the inside surfaces of the vertical portions of the frame. As a result, the infiltration of an electric field toward the fluorescent surface 9 through the holes of the acceleration electrode 23 is reduced to prevent the electric field from being disturbed by the vertical portions of the frame 25 to cause color phase irregularity at the horizontal ends of the screen of the device.

摘要： PURPOSE:To improve the reliability of an image displaying equipment by providing uniform ratio of the cross sectional area of an electrode to flat of a spacer in the respective Y-Z planes thereof all over the X-Y plane, where the picture screen is assumed as X-Y plane. CONSTITUTION:As the figure shows, a slit 39 is formed in the spacer 38 an outer frame joint and the cross sectional area of the spacer 38 is made small and the ratio of the cross sectionals area of the spacer 38 to that of an electrode is made equal to that in the central jointed part, hence no difference is produced in reduction of size due to calcinate joining. Thereby, the pitch irregularity in central portions of respective electrodes and near the out frame can be reduce to about 5mum or less and high quality of the image display device can be produced.
