2. how do we see image
3. refresh rate
4. how to reduce flicker/discomfort

|
1. CRT (Cathode Ray Tube) was the technology first used in TV sets 2. 3 colour electron guns (rbg), shoot beams of electrons many times on screen per second to constantly redraw image 3. refresh rate of 60Hz = redraws image 60 times per second 4. increase refresh rate, reduce the amount of eye discomfort |

CRT Monitor (inside)
1. function of metal plate inside monitor
2. process of removing it
3. how is this done

|
1. shadow mask picks up external magnetic fields which cause discoloration 2. degaussing - reverts colour back to normal 3. usually done when PC turns on OR can be activated by a button |
| LCD Monitor 1. definition 2. how 3. TFT | 1. LCD (liquid crystal display) monitor produces an image on a flat surface by using liquid crystals 2. light shines through these crystals to produce an image on screen, using filters to make different colours 3. uses a TFT (thin film transistor), to create higher quality images as each single pixel on the screen has its own transistor |
| LCD monitor lighting types 1. Florescent 2. LED | 1. Uses florescent lamps for back lighting. Emits UV light when the mercury vapor inside the lamp is ionized 2. Uses multiple LEDs arranging in a pattern - modern and new form of back lighting |

LCD monitor - Twisted Nematic (TN)
1. how
2. Found on..
3. pros & cons

|
1. liquid crystals twist the light as it comes through. 2. calculators, digital watches and older LCD monitors/laptops 3. + faster refresh rate (gaming) + low power draw - poor viewing angles - colour shifts |
|
LCD Monitor - In-Plane Switching (IPS)
1. how
2. pros & cons
Image:
Curve (image/png)
|
1. liquid crystals stay in place, aligned in parallel with the glass 2. + better colour, + no tailing when touched (mobile), + viewing angles - more expensive, uses more transistors = more power |
|
Resolution
1. definition
2. native resolution
3. contrast ratio
Image:

|
1. number of pixels that are used to display an image on screen (WxH), higher resolution = more pixels used = clearer 2. when its set to the highest resolution 3. contrast between black and white - higher contrast = better display |
