Description of the invention (ο «The present invention discloses a color image tube with a shadow mask forming a hanging relationship with a glow screen, and in particular discloses an improved type Lighter shadow mask. Because the size of the color image tube increases, the size and weight of the κ image tube sister parts increase most. The shadow mask frame sister fit is one of the sister parts. The current color image tube A steel frame is used to support the shadow mask in the image tube panel. One of the frames is made of continuous L-shaped mesh, that is, the mesh a is bent and welded at both ends. The frame Another type * is made by squeezing a flat screen into a frame shape. Typically, it is used for a 31V image tube with a 7-9 cm diagonal screen pedestal, the frame is made of about 1.00 cm (0.03 9 British Hours> Thickness a is made of a material weighing about 1.63 kilograms (3.6 pounds). Other frames can be as thick as 1.51 boxes of rice (0.062 pounds) and more proportionally The frame is usually rectangular in shape and supported by three or four springs attached to the sides of the frame In the panel; alternatively, the frame can be supported at its four corners. US Patent No. 4.723,088 issued to Sonne et al. On February 2, 1988, and March 1, 1988 U.S. Patent No. 4,7 2 8, 8 5 3 issued to Sone, etc. as shown in the Japanese example, this embodiment of the corner support is used. Because the conventional mask frame sister fit is quite heavy * If the support frame can be removed, it is necessary. There is an opportunity to reduce the weight of the image tube. The present invention provides a shadow mask that does not use a conventional frame. An improved color image tube according to the present invention includes a vacuum package with a rectangular panel. The panel includes a The development screen on the surface, and a shadow mask assembled therein. The shadow mask includes a perforated outer shape portion and a reinforced structure with the periphery attached to the perforated portion. The reinforced structure and the mask portion are in the mask A box-shaped shell is formed around the perimeter.

It includes a rectangular panel and a tubular neck 14 to which a rectangular funnel 16 is connected. The panel 12 includes a display panel 18 and a peripheral flange or side wall 20 which is hermetically connected to the funnel portion 16. An inlaid tri-color phosphor screen 22 is positioned on the inner surface of the panel 18. The screen is preferably a line screen with parallel phosphor lines extending vertically. Alternatively, the screen may be a dot matrix screen thin. A porous color selection electrode or shadow mask 24 is movably assembled to the screen 22 to form a predetermined interval relationship. The e-frame 25 is assembled in the central part of the neck 14 to generate and guide three electron beams along the collecting path through the mask 24 to the screen 22. The design of the image tube in Figure 1 is used in conjunction with an external magnetic yoke 28 positioned near the junction of the funnel and the neck. When activated, the yoke 28 exposes the three thunder beams to the magnetic field, causing the electron beam to scan the screen 22 horizontally and vertically in a rectangular grating.

Description of the invention (5) • The shadow mask 24 shown in detail in FIGS. 2 and 3 includes a perforated outer shape portion 26 and a peripheral measuring edge 30 surrounding the perforated portion 26. The shadow mask is installed in the panel 12 with four supporting devices positioned at four corners of the shadow mask. Figure 2 shows one such support device 34. Each supporting device 34 includes a screw pile 36 embedded in the panel side 20, a spring 38 that engages the screw, and a bracket 40 attached to the shadow 3 side and edge 30. Alternatively, the shadow mask 24 may be positioned to hang along a support device along the edge of the shadow mask. After the shadow mask 24, there is a thick peripheral reinforced frame 3 described in the conventional technique, ^ _____ 一一-— ·-一 —— 一-Alternatively, the side edge 3 0 of the shadow mask 24 j so that the periphery is attached to the inner surface of the side edge 30 to strengthen the C-shaped strengthening structure 4 g). The C-shaped structure 42 is formed by a pure angle and a right-angled cross section. The reinforced structure 42 and the measuring edge 30 form a rigid box-shaped casing 43 in the shaded S periphery, and have the reinforced structure to form three sides of the casing. The material structure of the reinforced structure 42 has approximately the same thickness as that of the mask material, that is, 0.229 cm (0.090 inches). The structure is likely to be as thick as 1.5 cm (0.5 mm). 0 6 2 English hours) The thick conventional frame is much thinner. Therefore, because the reinforced structure is 42 lighter than the conventional technical frame, it is much lighter than the conventional technical frame, so the shaded cover with box-shaped peripherals is very light compared to the heavy one. The conventional shadow mask frame of the peripheral frame fits together. Figures 4, 5 and 6 show the spring 38 and the bracket 40 in detail. One end of the spring 38 is welded to the bracket 40, and the other end of the spring includes a hole 44 for engaging the screw 36. The bracket 40 includes a central portion 46, and two legs 48 and 50 to which the spring 38 is welded. The legs 48 and 50 extend along the adjacent edges of the shadow mask and are welded to the side edges of the shadow mask 30 The outer surface.

Description of the invention (4) The shadowy surroundings The gong structure can be formed with parts of different shapes. For example, FIG. 7 is a preferred example of a small correction. In FIG. 7, the shadow mask 60 shown has a box-shaped housing 6 1 * which has a cross section It is formed by two right-angled C-shaped reinforced structures 62. In 鈃 8, an iron-chain mask 70 has a U-shaped side edge 72, which forms a box-shaped peripheral 7-2 side. Outer valley 7 3 other The side is formed by the outer surface of the side edge 72 attached to the peripheral point and the U-shaped bottom of the side edge attached to the peripheral point 78. The flange 79 of the structure 74 extends toward the center of the shadow mask as a thunder The beamlets are overscanned. The shadow mask 80 shown in FIG. 9 is similar to the embodiment of FIG. 8 except that the structure 84 contacts the side edge 82 and the il-shaped outer portion. The shadow S has a box-shaped housing 86 The U-shaped side edge 82 and the C-shaped structure 84. The shadow mask and the shadow mask support device manufactured according to the present invention use the least amount of materials and are significantly lighter than the shadow mask using the frame. This results in lower costs, Better thermal performance and reduced warpage during long hours of operation. The thinner material with enhanced structure is easier to process and the finished product is shaded The sister fit and support are still strong enough to withstand mechanical shock and vibration.
