CRT, LED And LCD Wireless Computer Monitor
We use wireless computer monitor on a daily basis spending much time in front of them but on the other hand it is really fascinating that we basically know just a little about them. Most people do not know how they work; many also do not know which types of computer display screens are available on the market.
On following page here on my site, I will do my best to explain and reveal most important things and factors related to computer monitor just like aspect ratio, refresh rate, resolution, dot pitch, also I will write about LED, LCD, OLED and CRT monitors and many more related things. Spend few minutes and you will find out much!
First wireless computer monitor, as you probably know, user cathode ray tube for image reproduction and we call those types of monitors CRT. New devices available on the market use thin film of transistors called TFT. Those are used in LCD monitors and also in LEDs (I will explain similarities and dissimilarities of LCDs and LEDs later in article). As every computer needs to have monitor, it is most used output device. Its job is to reproduce data from computer and display it in form of text and graphic.
Many times when people are speaking about monitors they say “flat screen” or “flat panel” but in many cases they really do not understand what the difference between them is. Easiest way to separate flat screens from flat panel is to take a look at next image.
Flat Screen vs Flat Panel comparison of computer display screens
So, now when we know and understand that we have two major types of wireless computer monitor: CRT and LCD, and when we understand what are flat screen display screens are in fact CRT while flat panel displays are LCDs and LEDs, we may proceed. First of all, let’s say something about CRT displays.
Flat Screen CRT wireless computer monitor
Very first wireless computer monitor used cathode ray tubes (from that we have term CRT) for image and graphic reproduction. Earliest models in 1980s were video display terminals and monitors were physically attached to the keyboard and computer. They were monochrome and because of that image quality was very poor. With advancements of computer technology and IBMs invention of color graphic adapter and enhanced graphic adapter later in 1984 wireless computer monitor were producing 16 colors. Through 1980s and 1990s CRT monitors and technology was dominant on the PC market mainly because of cheap production cost.
Comaprison of sizes of CRT and LCD and LED monitors
From the beginning of year 2000, demand for CRT monitors have dropped significantly mainly because of lower price of LCD monitors. CRT is officially dead technology as brand name manufacturers do not produce those anymore.
