Accelerating and focusing anodes turn the electrons into a fine beam that is directed to the phosphors by magnetic fields that are generated by steering coils. The CRT works by heating a cathode which causes electrons to flow.

Likewise, TV sets no longer use CRTs (see flat panel TV). Today, "monitor" is the correct term as computer displays have long since migrated from CRTs to LCD panels (see flat panel display). In the past, CRT was a popular term for a computer display terminal. The viewing end of the tube is coated with phosphors, which emit light when struck by electrons. (2) ( Cathode Ray Tube) A vacuum tube used as a display screen in a computer monitor or TV.

High definition CRT TVs always have the full 1080 lines and can change their resolution for viewing standard definition TV shows (without upscaling). Graphics professionals still use CRT monitors because they have the best picture quality. CRT is the only kind screen which actually let’s you change the resolution (not just upscaling or downscaling which makes the picture look soft). LCDs have poor color accuracy and contrast and plasma TVs get severe burn-in (meaning the screen can be ruined by static images commonly found in video games or even a TV channel's logo at the corner of the screen). Magnets near the back of the tube bend the beams and make it scan across the screen like reading a book while the beams are made stronger or weaker (or turned off completely) to make different parts of the screen dark or light or different colors. In a CRT three electron guns (one for red, one for green and one for blue) shoot narrow electron beams (electrons are what electricity is made of) through a tube with no air in it to the screen which is coated with phosphor, a substance which glows when electrons hit it. The best kind of screen! They’re the normal looking ones, i.e. That is why the law must be examined for its words *and* its effects when People of Color are adversely affected by the same laws that do not punish white citizens." If it happens over and over and always to the benefit of the white citizens, it can't be a mistake. Denier: I don't believe you, it must have been a mistake! Believer: If it only happened once, it's a mistake. And the only difference was the color of their skin. We treated people with powder addictions and jailed people with crack addictions. Denier: So? Believer: They are the exact same drug and the exact same dosage. Believer: The sentencing for crack cocaine is 100x longer than powder cocaine Denier: They are both illegal, who cares which is longer? Believer: At the time, powder was predominantly used by whites and crack was used predominantly by People of Color. "I think we are a long way from the 3/5ths compromise and slavery being legal, but we have a long way to go and I believe we need people who believe in CRT to root out racism from our legal codes." " Denier: Show me an exact time where CRT proves a law exists. What they miss is the fact that case law is *always* anecdotal and it's still legally binding so long as the courts use previous cases to set a precedent the courts use today. Opponents of CRT complain that it relies too heavily on storytelling and anecdotal evidence instead of strictly reading the laws. The evidence, which is proven to be statistically relevant, speaks for itself and to deny that evidence clearly shows a disconnect with reality. It has become a political point as politicians deny the results of investigations that consistently find that the legal wording and the subsequent case law adversely affect people of color. It differs from Critical Legal Studies ( CLR) by narrowing it down to race and excluding other concerns, such as sexism. CRT is a way of examining the law and societal structures to identify how they contribute to racial oppression. It is founded on the idea that white supremacy is real and the law is written to support that supremacy. Critical Race Theory has been around since the '70s in the academic world which studies how race and the law intersect.
