In order to obtain a stable display effect, the electron emitting end needs to emit electrons in a vacuum environment where the vacuum pressure is less than 1G—Peach. Therefore, the Fanfa 2 display needs a good vacuum seal to ensure its internal vacuum environment. The X conventional technique uses a getter in the field emission display to obtain a better vacuum ring. The second picture of the tea, U.S. Patent No. 5,688, View No. (Announcement date is the 18th day of the bile year), discloses a field emission display ⑽, comprising: an anode plate 102 covered with a fluorescent layer 104, The cathode plate 106 of the plurality of electron emission terminals 108 and the side wall 112 disposed between the cathode plate ⑽ and the anode contact ，, and a certain distance is formed between the side walls 112. A glass material is used for sealing (not marked). The side wall 112 is fixed on the cathode plate 106 and the anode 102 only to form a sealed area. □ Draw the next page (when it is said that bribes are not enough, _ 雠 note and Lai Xian) 5 200407932 Description of the invention $ Sale page Λ 射 Rabbit shooting display device 100 further includes a plurality of receiving chambers 118 communicating with the sealed area. The getters 120 and 122 are respectively contained in different containing chambers 118. The first and second getters 120 and 122 can remove residual gas in the sealed area to improve the vacuum environment. However, the field emission display 100 has a plurality of receiving chambers 118 making it larger in volume, and the receiving chambers are larger because of the receiving chambers. Protruding outwards makes it inconvenient to install into the system. In addition, the thermal expansion coefficients between the glass material sealant, the pole plate 106, the anode plate 102, and the side wall 112 are different. For long-term use, the cathode plate 106, the anode plate 102, and The seal between the side walls fails, reducing the life and reliability of the field emission display. _ [Objective of the Invention] The purpose of the present invention is to provide a dense arrangement of a secret indicator with good sealing and strong structure.
