Types of LCD |
LCD, LED, OLED |
|
|
Two common classes of LCD |
Twisted Nematic TN In Plane Switching IPS |
|
|
Types of Backlighting |
Cold Cathode Fluorescent Lamp CCFL light emitting diode LED |
|
|
CCFL characteristic |
Older technology Use of two or more fluorescent tubes to light back panel Inverter circuit boards provide power to fluorescent lights |
|
|
LED backlight characteristic |
Receives DC power direct from motherboard No need for inverters Better range accuracy colour Less power than CCFL More environmentally friendly |
|
|
Plasma Characteristic |
High Contrast Better color than LCD Larger in size Bad image burn |
|
|
OLED Organic Light emitting diode |
Thin led layer between two grids of electrodes No Backlighting Most environment friendly Better contrast Faster refresh rates Low power consumption Thin design Has bad glare |
|
|
Refresh rate |
Number times screen is refreshed in one second. Measured in Hz cycles per sec The higher the better |
|
|
Response time |
Time to build 1 frame Measured ms milliseconds Lower the better Related to refresh rate |
|
|
Comparison |
TN older cheaper, best response (good gaming) IPS better angles, colours |
|
|
Resolution |
Maximum number of pixels in each dimension horizontal and vertical that can be addressed. |
|
|
Native resolution |
Number of pixels built into LCD monitor usually gives highest image quality |
|
|
Cd/m^2 |
Brightness measured Cadela per square metre |
|
|
Aspect ratio |
The proportional relationship between width and height. The relative horizontal and vertical size of digital image displayed on screen |
|
|
Inverters |
Supply voltage to backlights of LCD panel Converts DC power to AC |
|
