OLED VS LCD in 2018

OLED VS LCD in 2018

• What has evolved since now in both of these
  technologies?

2
Current Scenario in Display Technology

• Earlier the LCD had a competition with Plasma,
  but now the Plasma is out of the competition and
  is outdated to use now. OLED is the new display
  technology giving tuff competition to LCD and is
  proven better than LCD in many aspects according
  to the user reviews.

How LCD works?

• We all know that a picture displayed on a
  television consists of millions of pixels which
  are either red, green or blue and they
  collectively form a picture for us to see.

• In an LCD television, the pixels are switched on
  or off electronically using liquid crystals to
  rotate polarized light, it has a large bright
  light that shines out toward the viewer and
  liquid crystals manipulating It to create an
  image.

What powers OLED to display a crystal clear view ?

• OLEDs have layers of n-type and p-type
  semiconductors, they use organic molecules to
  produce their electrons and holes. A simple OLED
  is made up of six different layers of
  protective glass or plastic. The top layer is
  called the seal and the bottom layer
  the substrate.

• In between those layers, there's a negative
  terminal (sometimes called the cathode) and
  a positive terminal (called the anode). Finally,
  in between the anode and cathode are two layers
  made from organic molecules called the emissive
  layer

Which has a awesome Light output ?

• LCD gets the nod here specifically because the
  whole screen can be brighter, a function of
  its backlight. OLED can't do a full screen with
  as much brightness. Full-screen brightness isn't
  very important in the real world however, so this
  category is a relatively hollow victory for LCD.

• Light output also plays a big part in High
  Dynamic Range (HDR).

6
Which one takes the lead while considering Black
level?

• At the other side of light output is black level,
  or how dark the TV can get. OLED wins here
  because of its ability to turn off individual
  pixels completely. It can produce truly perfect
  black.

• The better LCDs have local dimming, where parts
  of the screen can dim independently of others.
  This isn't quite as good as per-pixel control
  because the black areas still aren't absolutely
  black, but it's better than nothing. 

7
Which is the best when it comes to Contrast ratio?

• Here's where it comes together. Contrast ratio is
  the difference between the brightest and the
  darkest a TV can be. OLED is the winner here
  because it can get extremely bright, plus it can
  produce absolute black with no blooming. It has
  the best contrast ratio of any modern display.
• Contrast ratio is the most important aspect of
  picture quality. A high contrast-ratio display
  will look more realistic than one with a lower
  contrast ratio.

8
Who ranks first in terms of Resolution?

• This one's easy. Both OLED and LCD are widely
  available in Ultra HD 4K form. There are also
  plenty of 1080p LCDs. Some older OLEDs are 1080p,
  but new models are all 4K.

9
Which one is best at Refresh rate and motion blur?

• Refresh rate is important in reducing motion
  blur, or the blurring of anything on screen that
  moves (including the whole image if the camera
  pans). Sadly, the current version of OLED has
  motion blur, just like custom LCD screen that
  makes both of them perform almost same in this
  segment.

10
Which one performs in providing better HDR?

• There are both OLED and LCD models that are
  HDR-compatible. The best HDR LCDs can produce
  brighter highlights than OLED, but OLED still has
  a better overall contrast ratio (dynamic range,
  if you will) thanks to its better black level.
  Which is to say, done well, both are good. You
  need HDR content though.

Which has a better Viewing angle?

• One of the main downsides of LCD TVs is a change
  in picture quality if you sit away from dead
  center
• A few LCDs use in-plane switching (IPS) panels,
  which have better off-axis picture quality than
  other kinds of LCDs, but don't look as good as
  other LCDs, primarily due to a lower contrast
  ratio, which enables OLED displays to score here.

12
Conclusion

• LCD dominates the market because it's cheap to
  manufacture and delivers good enough picture
  quality for just about everybody. But OLED wins
  for overall picture quality, largely due to the
  incredible contrast ratio.
