Specifications • Parameters that are not yet estimated • Driving Voltage • Cost • Contrast • Weight • Lifetime
Conclusion • The market seems to be very attractive. • The fundamental blocks of the display are defined. • The overall tasks are assigned to the different work groups. • Some improvements are understudy.
Exemples: switchingspeed • Each pixel lit per 17 ms (20 Europe) beforebeenredrawn • LCD : 20 ms in year 2000 (uselessfor video apps) 2 ms moderndisplays. • CRT : < 1ms. • OLED : 0.001 ms. • Plasma : 0.001 ms. • Techniquestoincrease the switcingspeed: • Boost the drivingvoltage • Super sampling : built intermediate frames
Exemples: cost & resolution & weight • Cost: • OLED : ~ $24,000 per square meter • LCD : ~ $800 per square meter • Resolution: • Iphone : 362 ppi • Mirasol IMOD : 223 ppi • Ipad : 132 ppi • Weight : • Ipad : 132 g for 241x185mm
Exemples: Contrast & drivingvoltage • Contrast: ratio of the luminance of the brightest color (white) to that of the darkest color (black) • LCD : 5000 : 1 Dynamic (underpowerbacklight) • 1000 : 1 Static • CRT : >3000 : 1 Static • Plasma : 5000 : 1 Static • OLED : 2000 : 1 to 1,000,000: 1 (in a perfectly dark room) • Drivingvoltage: dependof the battery: • Iphone : 3.7 V • Ipad : 3.7 V
Exemples: Powerconsumption (mW) • Operating Assumptions: 80% active time in an office, 10% in bright light and 10% at night (dim light) • Display power includes the display plus backlight power for an LCD and frontlight power for an IMOD • source : PikeResearch
