LIGHT EMITTING DIODE
Comparison Of Chip Technologies For Wide-Angle, Non-Diffused LEDs
Organic light-emitting diodes (OLEDs)
High contrast
Fast response at any temperature
Thinness – eventually ~ one glass substrate or <0.5 mm
Wide viewing angle, essentially a Lambertian emitter
Good colour reproduction
Simple structure and inexpensive bill of materials (BOM)
HDTV OPTICAL ARCHITECTURE
What makes 7040 the perfect LED Backlight Driver ?
Active VS. Passive Display
Why is LED technology in TV is advantageous?
LED TV can better handle darker tones - It can achieve deeper blacks as well as emit brAighter images. It can also achieve better contrast ratios.
It is slimmer - With the Edge-LED lighting system, LED TVs can be made
It has better viewing angles - Even the most expensive LCD TVs still suffer from providing the viewer with excellent picture and viewing quality, especially when the person is away from the center. LED TVs fare much better in this aspect, perhaps another reason why it is being used outdoors with huge number of audiences.
LEDs last longer - LEDs have longer life than LCDs and often more durable.
LEDs are more energy efficient - While LEDs are capable of providing lower power consumption, some LCD TVs can actually match it in terms of energy usage.
