Description
【０００１】0001
本考案は、鏡面な外表面に帯電防止を付与したブラウン管用パネルに関する。 The present invention relates to a cathode ray tube panel that has a specular outer surface that is antistatic.
【０００２】0002
一般にブラウン管は高電圧を印加して作動させるため、スイッチの切り換え時 等にパネルの外表面に静電気が帯電し、この静電気のために、パネルの外表面に ほこりが付着して見にくくなったり、パネル外表面に手等が触れたときショック を受けることがある。このために、ブラウン管特にディスプレイ用ブラウンに於 いてはパネルの外表面に帯電防止の作用を具備することが望まれている。 Generally, cathode ray tubes are operated by applying high voltage, so when switching etc., static electricity is charged on the outside surface of the panel, and due to this static electricity, the outside surface of the panel is charged with static electricity. If dust accumulates and makes it difficult to see, or if you touch the outer surface of the panel with your hand, you may receive a shock. may be received. For this reason, in CRTs, especially CRTs for displays, Therefore, it is desired that the outer surface of the panel has an antistatic effect.
【０００３】 従来、この帯電防止に関し、夫々個々には種々の提案がされているが、安価で 信頼性がありかつ量産に適したブラウン管用パネルは得られていないのが実情で ある。0003 In the past, various proposals have been made for preventing static electricity, but there are some inexpensive and The reality is that reliable cathode ray tube panels suitable for mass production are not yet available. be.
【０００４】0004
本考案は、上記事情に鑑み、良好な帯電防止特性を具備したブラウン管用パネ ルを提供することを目的とする。 In view of the above circumstances, the present invention was developed to develop a cathode ray tube panel with good antistatic properties. The purpose is to provide the following information.
【０００５】[0005]
本考案は、ガラス製パネルの鏡面な外表面上に、ＳｎＯ2 の導電膜を１０〜２ ００Å厚さに形成してなるブラウン管用パネルであることを特徴にする。The present invention is characterized in that it is a cathode ray tube panel in which a conductive film of SnO 2 is formed to a thickness of 10 to 200 Å on the mirror-like outer surface of a glass panel.
【０００６】[0006]
本考案では、パネルの鏡面な外表面上に薄い導電膜が形成されており、これに より良好な帯電防止特性を有することになる。 In this invention, a thin conductive film is formed on the mirrored outer surface of the panel. It will have better antistatic properties.
【０００７】[0007]
【実施例】 以下図１を参照して本考案を説明する。同図はブラウン管の全体を示し、ガラ ス製のパネル１０とファンネル１１とが溶着もしくはフリットガラス封着されて いる。パネル１０の外表面１２は、予め研磨により鏡面に作製してあり、その鏡 面な外表面１２上にはＳｎＯ2 の薄い膜１３が被着形成してある。ＳｎＯ2 の導 電膜の厚みは１０〜２００Å、好ましくは５０〜１５０Åとし、膜抵抗値を１０ 9 〜１０11Ω／ＳＱにするのが適当であり、膜厚が１０Å以下であるときは十分 な帯電防止の特性を発揮し難く、一方膜厚が２００Åを越えるときはパネルガラ ス表面の反射が増大してＴＶ画像が見にくくなる。ＳｎＯ2 の導電膜１３を形成 する場所は、パネル１０の外表面１２であるが、それの有効面１２’のみならず 側面１２" まで形成すると、この導電膜１３をブラウン管の防爆強化のためにこ の側面１２”上に設けられる金属製バンド１４に電気接続してアースすることが できて好ましい。【Example】 The present invention will be explained below with reference to FIG. This figure shows the entire cathode ray tube. The panel 10 made of stainless steel and the funnel 11 are welded or sealed with frit glass. There is. The outer surface 12 of the panel 10 is made into a mirror surface by polishing in advance. On the planar outer surface 12 is SnO.2 A thin film 13 is deposited thereon. SnO2 guidance The thickness of the electrical film is 10 to 200 Å, preferably 50 to 150 Å, and the film resistance is 10 9 ~1011It is appropriate to set the value to Ω/SQ, and it is sufficient when the film thickness is 10 Å or less. On the other hand, when the film thickness exceeds 200 Å, it is difficult to exhibit antistatic properties. Reflection on the surface of the screen increases, making it difficult to see the TV image. SnO2 forming a conductive film 13 of The location where the When the conductive film 13 is formed up to 12" on the side surface, this conductive film 13 is used to strengthen the explosion protection of the cathode ray tube. It can be electrically connected to a metal band 14 provided on the side surface 12" of the ground. It's nice to be able to do it.
【０００８】 上記説明の本考案のブラウン管用パネルを製作する場合、予め研磨により鏡面 に作製されているパネルの外表面にＳｎＯ2 の薄い導電膜を形成する。これには 、化学蒸着法が最適であり、例えば二塩化ジメチル錫（ＣＨ3 ）2 ＳｎＣｌ2 を 加熱し気化したガスを予め加熱したパネルの外表面上に吹きつけてＳｎＯ2 の薄 膜を形成する。尚、この際ドーパントとしてアンチモン化合物、例えば三塩化ア ンチモンＳｂＣｌ3 等を少量添加してもよい。しかしこの例に限定されずに他の 有機若しくは無機の錫化合物の原料を用いてもよいし、また膜形成法についても 浸漬法、スピニング法等によってもよい。When manufacturing the cathode ray tube panel of the present invention as described above, a thin conductive film of SnO 2 is formed on the outer surface of the panel, which has been previously polished to a mirror surface. The best method for this is chemical vapor deposition, in which, for example, dimethyltin dichloride (CH 3 ) 2 SnCl 2 is heated and the vaporized gas is sprayed onto the external surface of a preheated panel to form a thin film of SnO 2 . . At this time, a small amount of an antimony compound such as antimony trichloride SbCl 3 may be added as a dopant. However, the present invention is not limited to this example, and other organic or inorganic tin compound raw materials may be used, and the film forming method may be a dipping method, a spinning method, or the like.
【０００９】 本考案では、パネルの外表面が鏡面となっているのでその上にＳｎＯ2 の薄い 導電膜を均一な厚さで形成できる。In the present invention, since the outer surface of the panel is a mirror surface, a thin conductive film of SnO 2 can be formed thereon with a uniform thickness.
【００１０】0010
本考案は上述の如くパネルの鏡面な外表面にＳｎＯ2 の導電膜を形成すること により、良好な帯電防止特性を具備するブラウン管パネルが得られる。As described above, the present invention provides a cathode ray tube panel with good antistatic properties by forming a conductive film of SnO 2 on the mirrored outer surface of the panel.
