CRT：陰極射線管 (CRT: Cathode Ray Tube)

CRT is an abbreviation of Cathode Ray Tube. Cathode Ray Tube is a vacuum tube that accommodates one or more than one electron filled guns and a phosphorescent screen, which is used in television and conventional computer display. It operates by transferring electrons from the back of the tube in the direction of the display screen where it comes into collision with the phosphorous. The electrons light up and are projected on the display screen when they collide with the phosphorous inside the tube during the collision.

CRT是Cathode Ray Tube的縮寫 。 陰極射線管是一種真空管，可容納一個或多個電子填充槍和磷光屏，用于電視和常規計算機顯示器。 它通過從電子管的背面沿顯示屏的方向傳輸電子來與磷發生碰撞，從而進行操作。 在碰撞過程中，電子與管內的磷碰撞時，電子會發光并投射在顯示屏上。

The three lights Red, Green, and Blue produce the color displayed on the screen and frequently alluded to as RGB.

紅色，綠色和藍色這三個燈產生的顏色顯示在屏幕上，通常被稱為RGB。

Interference occurs, due to the Magnetic charges which are employed to show the way of electrons, when a speaker or other magnetic devices are placed near a CRT monitor. Magnetic charges are not used in LCDs and flat screens and this is the reason why they don't tackle these kinds of interference occurrence problems. In LCDs, the tube is also not present, due to which in comparison to CRT monitors their size looks much leaner. LCDs are superseding CRT monitors from both the markets of consumers as well as professionals because they very nearly match able with the standard of CRT monitors.

當揚聲器或其他磁性設備放在CRT監視器附近時，由于用來顯示電子方式的磁性電荷而產生干擾。 液晶顯示器和平面屏幕中不使用磁性電荷，這就是它們不能解決此類干擾發生問題的原因。 在LCD中，也不存在顯像管，因此與CRT顯示器相比，它們的尺寸看起來更小。 LCD已取代了來自消費者和專業市場的CRT顯示器，因為它們幾乎可以與CRT顯示器的標準相匹配。

特征 (Features)

• CRT has a huge physical size and a massive weight.

  CRT具有巨大的物理尺寸和巨大的重量。

• CRT has a much more effective ratio of contrast and in dark images gives more perceptible specific facts. While CRT shortfall to give blazing white intensities in the LCD.

  CRT的對比度要有效得多，而在深色圖像中，CRT具有更明顯的特定事實。 而CRT不足會在LCD中產生熾烈的白色強度。

• CRT is completely at a low price and getting disappeared from the market. Almost all the manufacturers have put an end to the CRT production and it is very strenuous to find it in the market.

  CRT的價格完全低廉，并從市場上消失了。 幾乎所有制造商都已停止了CRT的生產，因此在市場上找到它非常費力。

• CRT uses a ratio of 4:3 on the display screen. In conventional televisions, on top and bottom of the screen, a black bar is situated which shows that it is not prepared to use all the space of the screen. Whereas, LCD screens have much extensive width which shows that they have bar either small or not at all.

  CRT在顯示屏上使用4：3的比率。 在傳統的電視中，在屏幕的頂部和底部，都有一個黑條，表明它沒有準備好使用屏幕的所有空間。 而LCD屏幕的寬度要寬得多，這表明它們的條形很小或根本沒有。

CRT的基本組成 (Basic Components of CRT)

• Electron Gun: A beam of electrons is produced by an electron gun.

  電子槍 ： 電子槍產生電子束。

• Anodes: electrons are accelerated by anodes.

  陽極 ：電子被陽極加速。

• Horizontal and Vertical Deflection Plates: To modify the regulation of beam of electrons, these plates generate the low-frequency electromagnetic field which is needed.

  水平和垂直偏轉板 ：要修改電子束的調節，這些板會產生所需的低頻電磁場。

• Fluorescent Screen: phosphor is used to make the fluorescent screen. When the electrons hit on it, it releases light.

  熒光屏 ：磷是用來做熒光屏。 當電子撞擊在它上面時，它會釋放光。

• Evacuated Glass Envelope: The whole cathode ray tube is assembled or carried by an evacuated glass envelope.

  真空玻璃外殼 ：整個陰極射線管由真空玻璃外殼組裝或攜帶。

CRT的應用 (Applications of CRT)

• CRT is used in cathode ray oscilloscope.

  CRT用于陰極射線示波器。

• CRT is used in radar as a display device.

  CRT在雷達中用作顯示設備。

• CRT is used in televisions and monitors.

  CRT用于電視和顯示器。
