Abstract

Slot holes 5 and bridge portions 6 are formed throughout an effective region of a shadow mask, in which the slot holes are to be formed, such that a major side length L(x) of the slot hole 5 and a bridge width Bw (x) of the bridge portion 6 are gradually increased from a center portion of the effective region toward a peripheral portion thereof while maintaining a bridge width ratio R between the major side length and the bridge width in the center portion of the effective region, according to a bridge width determination function F(x).

The connection part 17 is given. Therefore, after the shutter is formed, the mechanical strength of the shutter is changed due to the deformation caused by the impact and the 1 1 thermally induced deformation such as the expansion of the steam chamber. Therefore, it is very important in terms of its influence on the irradiation characteristics. Important 〇1 I In order to improve the mechanical strength 9 of the shutter 14, the area of the bridging portion 1 1 16 can be increased. For example, it is basically possible to increase the 1 I area of the bridging portion 16 and thus increase the area as shown in Figure 6. The mechanical strength of the shutter 14 is improved by the degree 16a of the bridging portion 16 1 I in the slot hole shown.

Description of the invention (4) When the vertical pitch of each narrow hole in the mackerel hole irrigation is fixed under the condition that the width of the eaves joint portion 16 is added, it is necessary to reduce the main edge of the narrow hole.瑄 is incompetent because when the narrow hole is made smaller by one of the methods, the number of electrons in the edge will be reduced, which will reduce its illuminance. A method is disclosed in Japanese Patent Application Publication No. 6-275206, in which changing the joint size of the through-holes along the horizontal direction makes the center portion of the army smaller and then increases from its edge, or The plaque area from the central part to the middle part is fixed, and the peripheral edge of Lang quickly increases. In one of these technologies, the number of electrons reaching the fluorescent surface is reduced because the narrow opening area is partially reduced, which reduces the illuminance of the display screen.发明 糖 描述 _ The present invention is proposed under the above-mentioned problems, and the object of the present invention is to provide a time that can use the width of the joint portion of the shield and the main side of the narrow hole Become a proof color trench, and improve the mechanical strength of the shutter without reducing the illuminance on it. According to the present invention, a shielding plate for a color cathode tube is provided, and a narrow hole is formed in the neodymium region, which is arranged horizontally and parallel to each other. Each narrow hole includes涸 Rectangular narrow holes M and the joints between the narrow holes of each other. Each narrow gun hole has a tilt. The main side length is in the vertical direction. The width of the bridging part is from the horizontal direction. The central part of the effective area of the shutter gradually moves toward the periphery (please read the precautions on the back before filling this page) Order -i Υ · This paper size applies to China National Standard (CNS) Α4 size (210X297 mm) The central government presided over and the goods and workers' consumer cooperatives printed the policy A7 B7 5. The invention description (4) increased. The objective of the present invention is to provide a shield plate for a color cathode ray tube, in which an effective area is formed with a plurality of cranes arranged in a horizontal direction and parallel to each other. Each of the slit hole columns includes Several rectangular slit holes and bridging portions between adjacent slit holes and each slit hole has a main side length falling in the vertical direction, and the width of the bridging portion is effective from the shutter in the horizontal direction The central part of the area gradually increases toward the periphery, wherein the main side length of the slit hole increases proportionally with its degree β. Another object of the present invention is to provide a shield for a color shade tube, in its effective plaque area. Several horizontal slit holes are arranged on the horizontal direction and are parallel to each other. Each inclined slit hole machine includes several rectangular slit holes and a bridge portion between adjacent slit holes. Slot holes all have a major edge length that falls in the vertical direction. The bridging angle of the bridging portion gradually increases from the central part of the effective area of the mask to the periphery in the horizontal direction. The main side length of the slit hole follows it. Degree was gradually increased, wherein the width by the width of the bridge portion bridging the side length ratio of major central portion of the effective region of the slit aperture ratio determined are fixed in the entire effective plaque Cheng art. A further object of the present invention is to provide a shield for a color shade tube, in which a plurality of slits lanthanum arranged in a horizontal direction and arranged in parallel with each other are formed on an effective plaque field, and each inclined slit hole Contains several rectangular slit holes and bridging sections between adjacent slit holes, and each tilted slit hole has a tilt. The main side length is in the vertical direction, and the bridging degree of the bridge section is in the horizontal direction.
