Difference Between LED, QLED & OLED Television
Although marketing terminology like OLED, QLED, and LED may appear to be interchangeable, they actually refer to different types of panels.
A flat panel LCD TV that employs light emitting diodes (LEDs) for its backlighting instead of cold cathode fluorescent lamps ( CCFL).
PROS of LED TV's
- When edge mounted, screens are relatively thin.
- Reasonable brightness
- No burn-in
CONS of LED TV's
- Colors that can be displayed are limited
- Poor contrast ratio
- Black areas are never completely black
developed by Sony.
Between the backlight and the LCD, a layer of "quantum dots" is introduced in QLED.
PROS of QLED TV's
- More natural colour reproduction
- There is no need to back-off blue and green to compensate for the increased brightness.
CONS of QLED TV's
- Contrast ratio is low, although it's better than LCD.
- Because of the QD layer, the panels are slightly thicker.
OLED TV is a type of television display that uses the properties of organic light-emitting diodes (OLED). OLED television is not the same as LED television.
PROS of OLED TV's
- Colors that are true to life, with an infinite contrast ratio
- Response times are really fast, and there is a low latency option available.
CONS of OLED TV's
- It's not quite as bright as QLED, but it's close.
- LEDs' organic chemicals deteriorate with time, resulting in a short lifespan.
There are many different resolutions-
- Standard Definition (SD)
- High Definition (HD)
- Ultra High Definition (UHD)
OLED TVs offer a far faster response time than LED TVs since they can change each pixel on the screen practically instantly.
Cost of LED, QLED & OLED
OLED TVs are the most expensive, provide the best quality. QLED TVs are slightly more expensive than LED TVs, they are likely to provide the best value for your money.
TV technology has advanced to the point where there are now competing panel kinds, each with its own set of benefits and drawbacks.
