Display Technology Presentation Transcript:
1. TECHNOLOGIESCATHODE RAY TUBE (CRT)
LIQUID CRYSTAL DISPLAY (LCD)
PLASMA DISPLAY PANEL (PDP)
ORGANIC LIGHT EMITTING DIODE (OLED)
2. LCD
Most mature flat panel technology Major share of FPD market Poor intrinsic viewing angle Requires backlight Inefficient Slow Effected by Temperature and sunlight
3. Address electrode causes gas to change to plasma state. The plasma emits UV in discharge region which impinges on the phosphor Reaction causes each subpixel to produce red, green, and blue light.
4. OLED
Most promising technology Already in small sizes No inherent size limit Conformal displays Large viewing angle High resolution High Speed Good colour gamut Lifetime issues to be solved Great threat to LCD 2008?
5. TECHNOLOGY ATTRIBUTES
Attribute LCD PDP OLED Size < 15” >30” No limit Brightness nits < 100 <500>10000 Resolution Medium High High Inherent VA Small Large Large Efficiency lm/w 6 1 50 Colour gamut Good Good Good Manuf. cost Medium Medium Low
6. Thanks.
