After 106 years the death knell of the cathode ray tube is sounding. Hitachi sees no growth prospects in the market of the CRT so it is closing its 333+ million a year CRT plant. The LCD (Liquid Crystal Display) is increasingly replacing it. What took a major act of strength to lift can now be done with one hand through the use of the LCD.
Only 20% of the energy put into the CRT came out as light. The majority was used to maintain a temperature of 945º C as the operating temperature. The dropping price of LCD’s and slowing of the PC market have indeed sounded the death knell for the CRT.
