  2. History of Display Technologies • The display technologies have developed greatly ever since it began. The first displays that initiated the evolution of technological displays, lasted much longer than the ones we see everyday. An example is the clay tablets which was used to display and store information into your own personal archive. In 1970, companies started the development more advanced displays, implementing electrophoresis and electric fields into the process. Without the earlier creations and discoveries, we would not have the televisions, monitors, and handheld devices we have today. [6]

  3. There's more displays than you think... • The common: • CRT, LCD, Plasma, OLED, projection The less heard of: • SED, FED, IMOD, LCoS... Retrieved from [2]

  5. Touchscreens • “Touch screens are devices that allow a user to provide a computer or electronic system by making physical contact or near-contact with the system’s display.” [5] • Touch screens make the mouse obsolete because it replaces its function and is easier to use. • Touch screens enhances our hands amplifying our ability to touch and our finger dexterity Retrieved from [7]

  6. History of Touchscreens • Touch screens were most likely seen in the past on ATM machines because there are no moving parts so it can’t be stolen and no moving parts makes it sturdier. They were scarce in the past because they used to be built by hand but now it can be produced by machines. • Touch screens originated from the digitizing tablet developed by Dr. G. Sam Hurst in 1971. Retrieved from [4]

  7. Disadvantages • Although Touch screens bring us convenience, it still needs to be improved. Touch screen technology is commonly used where there are “finger use conditions”. • Capacitive touch screens do not work well with gloved hands or a stylus. And also they easy to get scratched when people have nails and there are finger prints and dirt on them after the first use.
