The term "liquid crystal diode" was invented by patent lawyers in late 1970's for the emerging liquid crystal display technology to rhyme with the then dominant light emitting diode display technology. The term is misleading as the liquid crystal cell is not a diode in the ordinary meaning of the word. Since then the incorrect term has been adopted to patents (over 600 patents describing liquid crystal cells as diodes) and scientific literature in addition to its misuse in lay-articles in internet.

Who invented the zener diode?
Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.
Who invented diode and when?
The first diode was the Galena Cats Whisker. It was invented shortly after the development of radio, but I'm not sure by who.Fleming's vacuum tube diode came shortly afterwards.
What are the early developments in electronics?
The earliest electronic device was the diode which was invented in 1873. The first diodes were both crystal and thermionic valve (vacuum tube) based devices; the first valve diode was in 1873, the first crystal diode in 1874. Edison also developed a diode independently. In the early 20th century, the first triodes were developed - which could amplify signals and electronics was largely valve based until the early 1960s, despite transistors being developed in 1923.
What is fulform of LCD?
LCD Liquid Crystal Display
What is the LCD of?
LCD is the abbreviation for Liquid Crystal Display.
Are LCD TVs the ones with the liquid in them?
Liquid crystal diode.
What does l c d mean?
Liquid Crystal Diode.
Lcd full form?
LCD is Liquid Crystal Display and LED is Light emitting diode.
What is led monitor?
A LCD (liquid crystal display) monitor with a LED (light-emitting diode) backlight
What has Ted Hoff invented?
Liquid Crystal Display ( L.C.D )
1 Who invented the liquid crystal display?
The liquid crystal display (LCD) was invented by George H. Heilmeier, a physicist working for RCA, in 1968. His work laid the foundation for the development of LCD technology that we use in many electronic devices today.
What is the Structure of LCD and LED?
LCD is liquid crystal display, used in computer monitors and handheld devices; LED is a light emitting diode, and are used in some TV's and devices. LED's are the small, bright lights, like a camera or phone flashlight.
What is a crystal triode?
A crystal triode is the old term for transistor. Crystal diodes were well established by the time transistors were invented, so using vacuum tube terminology, the logical name for a diode whose current could be controlled by a third element was "crystal triode".
What is a mechanical device that has been invented in the 2000s?
An LCD (Liquid crystal display) monitor.
Which diode has its characteristics very close to that of an ideal voltagesource.1.zener diode 2.vacuum tube diode 3. crystal diode?
The Zener diode has the characteristics of a constant voltage source.
Is LED stands for liquid emitting diode?
No. Light Emitting Diode
Who invented the zener diode?
Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.
