_4454. 81 _ 五、發明說明（1) ' 一 本發明是有關於一種彩色陰極射線管（CRT)。本發明 特別是有關於一種遮蔽罩幕（shadow mask)電極架構與遮 蔽罩幕電極支撐架構’其能改善彩色陰極射線管之影像品 質。_4454. 81 _ V. Description of the invention (1) '1 The present invention relates to a color cathode ray tube (CRT). In particular, the present invention relates to a shadow mask electrode structure and a shadow mask electrode support structure, which can improve the image quality of a color cathode ray tube.
在彩色陰極射線管中，大部份電子束係撞擊至遮蔽罩 幕電極。因此，遮蔽罩幕電極之溫度會上升。溫度上升會 造成遮蔽罩幕電極因熱膨服而變形。此變形會造成影像0 質之惡化。有必需避免影像品質因變形而惡化。為避免影 像品質惡化’從前’固定張力係施加至遮蔽罩幕電極。此 遮蔽罩幕電極係固疋至框’該框係施加沿著影像之縱軸方 甸固定張力至遮蔽罩幕電極。In a color cathode ray tube, most of the electron beams impinge on the shield electrode. As a result, the temperature of the shield electrode increases. The temperature rise will cause the shield electrode to deform due to thermal expansion. This distortion will cause deterioration of the image quality. It is necessary to avoid deterioration of image quality due to distortion. To prevent the deterioration of the image quality, a "fixed tension" is applied to the mask electrodes. The mask electrode is fixed to the frame. The frame applies a fixed tension to the mask electrode along the longitudinal axis of the image.
另一方面，遮蔽罩幕電極與周邊設備係裝置在彩色 CRT中。在製造過程中，遮蔽罩幕電極之溫度約上升至4〇〇 X： ~ 500 °C。。在使用過程中，遮蔽罩幕電極之溫度約上升至 5〇°C〜1〇〇°C。在溫度上升時，必需避免遮蔽罩幕電極之緊 繃。為此，需要降低遮蔽罩幕電極與框體間之熱膨脹係數 之差異。為降低遮蔽罩幕電極與框體間之熱膨脹係數之差 異，遮蔽罩幕電極係由鐵組成，而框體則由丨3%鎳_鐵合金 所組成。或著，遮蔽罩幕電極與框體皆由鎳鐵合金所組 成。如上述，在從前，係有習知技術來降低遮蔽罩幕電極 與框體間之熱膨脹係數之差異。此設計理念在於，組合時 所施加之張力係以影像之縱軸方向施加至遮蔽罩幕電極， 此張力係維持到使用彩色CRT時。 然而，在張力只施加至縱轴方向之遮蔽罩幕電極之架On the other hand, the mask electrodes and peripheral devices are installed in a color CRT. During the manufacturing process, the temperature of the shield electrode rises to about 400 ×: ~ 500 ° C. . During use, the temperature of the shield electrode rises to about 50 ° C ~ 100 ° C. When the temperature rises, it is necessary to avoid the tightness of the mask electrodes. For this reason, it is necessary to reduce the difference in thermal expansion coefficient between the shield electrode and the frame. In order to reduce the difference in thermal expansion coefficient between the shield electrode and the frame, the shield electrode is composed of iron, and the frame is composed of 3% nickel-iron alloy. Or, the shield electrode and the frame are made of nickel-iron alloy. As mentioned above, in the past, there are conventional techniques to reduce the difference in thermal expansion coefficient between the shield electrode and the frame. This design concept is that the tension applied during the combination is applied to the mask electrode in the direction of the vertical axis of the image, and this tension is maintained until the color CRT is used. However, in the case where tension is applied only to the shield electrode of the longitudinal axis

Description of the invention (2) The structure 'when manufactured or used' has almost no tension in the transverse direction. This is because, in the above-mentioned conventional method, no tension is applied in the lateral direction during the combination. For this reason, the mask electrode has little resistance to deformation in the lateral direction of the image. Therefore, when manufacturing or using, temperature rise or external oscillation will cause the color quality to decrease, and it will easily shift from the design point. However, the conventional architecture described above cannot avoid the above-mentioned disadvantages. In view of this, the object of the present invention is to provide a color CRT to overcome the above disadvantages. The CRT provides a composition that shields the screen electrode and the supporting structure. Avoid expansion of shield electrode and / or degradation of color quality caused by external oscillations. The present invention is limited to a structure in which tension is applied only to the longitudinal direction of the image. The conventional architecture has not changed, but the appropriate material combination is selected. Even when the "combination" application system did not apply the proper tension along the longitudinal axis of the image, the proper tension was applied to the horizontal direction of the image itself, and it increased according to the temperature during use (50 ° C ~ 100 °. Therefore, the mask was masked. The resistance to deformation in the transverse direction of the image of the electrode is increased β because the resistance to deformation in the transverse direction of the image is increased, which can avoid the expansion of the mask electrode and / or the decline in color quality caused by external oscillations. Another purpose is to provide the material combination of the mask electrode and the supporting structure. Although the CRT (40 (TC ~ 500.00) is not applied during the manufacture of the CRT, the tension is not applied in the transverse direction of the image, and it will not cause any Wrinkle, slack and / or damage of crt. According to the first aspect of the present invention, in order to achieve the above object, it provides a color cathode ray sound in which one of the shield electrodes is shielded from each other. The two side walls are fixed so as to be supported on two opposite side walls of a frame,

Description of the invention (3) Applying tension only in the longitudinal direction of the image 'in the color cathode ray tube' When the temperature is lower than 200 ° C, the thermal expansion coefficient of the frame is greater than that The thermal expansion coefficient of the shield electrode, and when the temperature is below 350 C, the thermal expansion coefficient of the frame is smaller than that of the shield electrode. Because of the above combination, when using a color cathode ray tube (about 50 ~ 100 ° C), the thermal expansion coefficient of the frame is larger than the thermal expansion coefficient of the shield electrode. Therefore, proper tension is applied to the lateral direction of the image, so it can avoid the degradation of color quality due to thermal expansion and / or external oscillation in the lateral direction of the image. Even when manufacturing a color cathode ray tube (about 400 ~ 500 °), because the thermal expansion coefficient of the frame is smaller than the thermal expansion coefficient of the shield electrode, the tension is not applied to the lateral direction of the image. Therefore, wrinkles can be avoided Break, dent, and / or destruction, etc. According to the second aspect of the present invention, in the first aspect t, it provides a color cathode ray tube, wherein the mask electrode is made of nickel with a content higher than 34% but lower than 40%. It is composed of nickel-iron alloy, and the frame system is composed of nickel-iron alloy whose nickel content is higher than 40%. In order to explain the above material combination method, using temperature as a parameter, the relationship between the thermal expansion coefficient and recording ratio of brocade iron alloy is shown. In Figure 3. In Figure 3, for example, the relationship between the coefficient of thermal expansion between an alloy with a nickel ratio of 38% and an alloy with a nickel ratio of 40% is based on the temperature as a parameter. At 20t, the former is 1.6ppm 'The latter is 2.5Ppm. At 300t, the former is 4 lppm and the latter is 4.2ppm. In the range of 20t> 300, the former is always smaller. At 350 ° C, the former is 4.8PPII, The latter is 4.5ρρπ ^ Conversely, at 5CHTC, the former is 9.0 ppm and the latter is 8.21).
第6頁 五、發明說明（4) 在350 C〜500 C之範圍内，其大小關係沒有改變，亦即後 者總是較小。相似地，鎳比率為高於34%但低於4〇%之合金 與鎳比率高於40%之合金間熱膨脹率之大小關係是以溫度 當成參數。在。20 〇2〇〇 °c之範圍内，前者之熱膨脹率係較 小，而在35(TC〜500 t之範圍内，後者之熱膨脹率係較 小。因此，根據上述材質组合方式，在使用彩色陰極射線 管時（約5<rC〜1〇〇°C)，適當張力係在影像之橫向方向上方 加至遮蔽罩幕電極，因為框體之熱膨脹率係較大於遮蔽罩 幕電極。其能避免因影像之橫向方向上之熱膨脹及/或外 來振盪所造成之顏色品質下降。在製造彩色陰極射線管時 (約4 0 0〜5 0 0 °C )，因為框體之熱膨脹率係小於該遮蔽罩幕 電極之熱膨脹率’張力係不施加至影像之橫向方向上。因 此’能避免皺摺，凹陷及/或破壞等。 根據本發明之第三形態，在第—形態中，其提供一種 彩色陰極射線管，其中該遮蔽罩幕電極係由鎳鐵合金（36% 鎳鐵合金）所組成，且該框體係由42合金（42%鎳鐵合金）所 組成。 根據上述組合方式，在使用彩色陰極射線管時，適當 張力係施加至影像之橫向方向上’在製造彩色陰極射線管 時，張力係不施加至影像之橫向方向上。甚至，遮蔽罩幕 j 電極之熱膨脹率係很小，比如1.2(20°〇)至1.8(；1〇〇。〇)。 因此’能得到良好之彩色陰極射線管，其能更進一步避免 在影像之縱軸方向與橫向方向上之顏色品質下降。 根據本發明之第四形態，提供一種彩色陰極射線管，Page 6 V. Description of the invention (4) In the range of 350 C to 500 C, the size relationship does not change, that is, the latter is always smaller. Similarly, the relationship between the thermal expansion coefficient between alloys with nickel ratios above 34% but below 40% and alloys with nickel ratios above 40% is temperature as a parameter. in. The thermal expansion coefficient of the former is relatively small within the range of 200 ° C, and the thermal expansion coefficient of the latter is relatively small within the range of 35 ° C to 500 t. Therefore, according to the above-mentioned material combination method, color is used For a cathode ray tube (about 5 < rC ~ 100 ° C), the proper tension is applied to the shadow mask electrode above the horizontal direction of the image, because the thermal expansion rate of the frame is larger than the shadow mask electrode. It can avoid The color quality is reduced due to thermal expansion and / or external oscillations in the lateral direction of the image. When manufacturing color cathode ray tubes (about 400 ~ 500 ° C), the thermal expansion rate of the frame is less than the shielding The thermal expansion coefficient of the mask electrode is not applied in the transverse direction of the image. Therefore, it can avoid wrinkles, dents, and / or damage.

According to the above combination, a color cathode is used At the time of wire tube, proper tension is applied to the transverse direction of the image. 'When manufacturing a color cathode ray tube, tension is not applied to the transverse direction of the image. Even the thermal expansion coefficient of the shielding electrode j is very small, such as 1.2 (20 °) to 1.8 (; 100.). Therefore, a good color cathode ray tube can be obtained, which can further avoid the degradation of color quality in the longitudinal and lateral directions of the image.

Shielding curtain electrode 14 pairs of two: two and the curved surface of the cylinder. The shield electrodes 14 are supported on each other by more than 1 I anthracene tightly fixed to be supported by spot welding and similar methods == curtain electrode support portion 13. Furthermore, the mask electrode 14 masks the entire opening on the upper surface of H φ. However, the two dotted lines only represent the shielding. The peripheral parts of the four side walls of the curtain electrode 14 are for easy illustration. Therefore, the shielding mask electrode 14 is made of nickel-iron alloy (36% nickel-iron alloy). The frame 11 is composed of 42_ alloy (42% nickel iron alloy). The frame 15 is composed of 13% chromium-stainless steel.
從組合時，張力係沿著影像之縱軸方向（短侧）施加至 遮蔽罩幕電極1 4之兩個側。在使用時，影像之縱轴方向上 之張力係維持著。因此，影像之縱軸方向上之張力避免因 使用時之影像之縱軸方向上之熱膨脹或外來振盪所造成之 顏色品質下降。另一方面，在組合時，並沒有施加張力至 橫向方向（長軸）。然而，在使用時，遮蔽罩幕電極支撐體 12之溫度變為50 °C〜100 t。遮蔽罩幕電極支撐體12之擴張 率係大於遮蔽罩幕電極14之擴張率。影像之橫向方向上之 適當張力係根據其效果而施加。因此，其能避免因外來振 盈所造成之影像之橫方向擴張及/或顏色品質下降。甚 至’在製造時（約400 0500 °C) ’遮蔽罩幕電極支樓體12When assembled, tension is applied to both sides of the mask electrode 14 along the longitudinal axis (short side) of the image. In use, the tension in the vertical axis of the image is maintained. Therefore, the tension in the direction of the vertical axis of the image avoids the degradation of color quality caused by thermal expansion or external oscillation in the direction of the vertical axis of the image during use. On the other hand, no tension is applied to the lateral direction (long axis) during assembly. However, during use, the temperature of the shield electrode supporting body 12 becomes 50 ° C to 100 t. The expansion ratio of the mask electrode support 12 is larger than the expansion ratio of the mask electrode 14. Appropriate tension in the lateral direction of the image is applied according to its effect. Therefore, it can avoid the horizontal expansion of the image and / or the degradation of color quality caused by external vibration. Even ‘at the time of manufacture (approximately 400 0 500 ° C)’ the shield electrode support building 12

Explanation of the invention (10) The thermal expansion coefficient is smaller than the thermal expansion coefficient of the shield electrode 14. Therefore, the lateral tension of the image is not applied to the mask electrode 14. Therefore, it can avoid the wrinkle, slack, and / or destruction of the mask electrode 14 during manufacturing. Furthermore, in the second embodiment, the frame 15 is composed of cheap 13% chromium-stainless steel. Only the shield electrode support 12 is made of 42-alloy (42% nickel-iron alloy). Therefore, it can be manufactured at low cost. As described above, according to the present invention, in a mask electrode which only applies tension to the direction of the longitudinal axis of the image, the conventional structure is not changed, but an appropriate combination of materials is selected. Therefore, even when the tension is not applied to the horizontal direction of the image during the combination, the proper tension caused by the temperature rise will be applied to the horizontal direction of the image during use. Therefore, it can avoid lowering the color quality caused by the expansion of the mask electrode and / or external oscillations, and its deterioration, etc., because it is in the direction. It can avoid wrinkles, depressions and / or breakage tensions in the manufacture of color cathode-ray tubes that shield the screen electrodes. The tension is applied to the transverse lack of basins. Not: Although the present invention has been disclosed above in a preferred embodiment, the present invention Within the spirit and scope, it can be used as ::: Without changing the #_ 铭 H ^ π Γ of the present invention, change and retouch, so the scope of warranty should be treated as the attached application.
