Abstract:
A color cathode-ray tube in which the brightness is improved while using the conventional electron gun and emitter layer as such, which is characterized in that both or either one of panel glass (3) and safety glass (1) which are used at a front side of the tube comprise glass having the property that a spectral transmission factor with respect to electromagnetic waves in the vicinity of a wavelength of 580-700 nm is relatively higher than that with respect to electromagnetic waves in the vicinity of a wavelength of 430 nm and that with respect to electromagnetic waves in the vicinity of a wavelength of 530 nm.

PROBLEM TO BE SOLVED: To provide a stereoscopic image display capable of reliably preventing a crosstalk phenomenon while minimizing a decrease in the luminance of a displayed image. SOLUTION: The stereoscopic image display includes: an image display panel 1 that displays right-eye images and left-eye images in a regularly mixed pattern in a plane; a retardation element 3 disposed on an image output side of the image display panel 1 and including right-eye-image display portions 3a, corresponding to the right-eye images, and left-eye-image display portions 3b, corresponding to the left-eye images, which cause polarization so that the right-eye images and the left-eye images may be in different polarization state each other; a polarizing plate 2 disposed between the image display panel 1 and the retardation element 3; and a light-shielding layer 4 disposed between the image display panel 1 and the polarizing plate 2 so as to correspond to regions including boundaries between the right-eye-image display portions and the left-eye-image display portions of the retardation element 3.

PROBLEM TO BE SOLVED: To provide a stereoscopic display apparatus that enables appropriate sticking to the whole surface of an image display panel even if a light shield layer has any irregularities. SOLUTION: The stereoscopic display apparatus includes: the image display panel 1 for regularly mixing right-eye images and left-eye images within a plane and displaying them; a phase difference element 2 having a right-eye image display section 2a corresponding to the right-eye images and a left-eye image display section 2b corresponding to the left-eye images and used for carrying out polarization so that the right-eye images and left-eye images are different from each other in polarized state; the light shield layer 3 projecting so as to correspond to an area that includes a boundary between the right-eye image display section 2a and the left-eye image display section 2b; and an adhesive layer 4 formed so as to smooth the roughness of the light shield layer 3, and stick the image display panel 1, phase difference element 2, and light shield layer 3.

PROBLEM TO BE SOLVED: To provide a stereoscopic image display apparatus appropriate sticking to an image display panel even if a light shield layer has any recesses and projections. SOLUTION: The stereoscopic image display apparatus includes: the image display panel 1 for regularly mixing right-eye images and left-eye images within a plane and displaying them; a phase difference element 2 having a right-eye image display section 2a corresponding to the right-eye images and a left-eye image display section 2b corresponding to the left-eye images and used for carrying out polarization so that the right-eye images and left-eye images are different from each other in polarized state; the light shield layer 3 projecting so as to correspond to an area that includes a boundary between the right-eye image display section 2a and the left-eye display section 2b; and an adhesive layer 4 formed at least between the top face of the light shield layer 3 and the image display panel 1, and thereby sticking the image display panel 1, the light shield layer 3 and the phase difference element 2 with each other.

Abstract:
PURPOSE: To suppress the warpage of a glass substrate subjected to prescribed printing on its front surface by supporting the rear surface of this glass substrate at prescribed points and firing the glass substrate in the state that the warpage force toward the rear surface side by its own weight is held applied on the peripheral edges of the substrate. CONSTITUTION: The glass substrate 31 formed with the prescribed printed matter 38 on its front surface is placed near the central part of its rear surface on a supporter 1 placed on a transporting belt 2 and is transported to a firing furnace, where the glass substrate is fired in an atmosphere of, for example, 570 to 600 deg.C. At this time, the solids, such as glass and metals included in the paste of the printed matter 38 are sintered and the printed matter 38 shrinks so that the shrinkage force acts in the warping direction on the front surface side of the glass substrate 31 but this force is suppressed by the force generated by its own weight of the glass substrate 31. The printed matter 38 of which the front surface is exposed to the outdoor air is more liable to be cooled than the glass substrate 31 placed on the supporter 1 at the time of cooling after the firing. Since the coefft. of thermal expansion is large, the force tending to warp to the front surface side acts on the glass substrate 31 but in this case as well, this force is suppressed by the force generated by its own weight of the glass substrate 31.
Abstract:
PURPOSE:To correct miss landing of a panel fluorescent screen peripheral part by forming a recessed part in a partial shape of a cylinder shape expressed by a prescribed expression in a central part of an X-Y axis directional surface of a flat lens having the same thickness in the Z axis direction. CONSTITUTION:In a flat lens having the same thickness in the Z axis direction of a three-dimensional space of a correcting lens 9, a recessed part in a partial shape of a cylinder shape expressed by an expression I is formed in a central part of an X-Y axis directional surface. When this lens 9 is used, a stripe pattern of an X-Y axis plane of a panel fluorescent screen can be corrected in a prescribed position. In this case, since the stripe pattern is dislocated in a curve shape in a peripheral part of a panel fluorescent screen, a stripe of the panel fluorescent screen is formed in the same position by the lens 9 to adjust. Thereby, a symmetric pattern of the panel fluorescent screen peripheral part of miss landing can be corrected.
