Because a little deep we will go about the iPhone X display screen.

Samsung is a big company that makes the OLED screens for iPhone X.

Samsung the main and first supplier of OLED screens from the beginning, it makes A-series processors and supplies both NAND flash and DRAM memory chips.

when apple used Samsung for patent infringement, it started to supply fewer components to apple since 2011.

In the iPhone, the most expensive components are display panel and memory chips.

Samsung will be the main supplier for hundreds of companies. If it adds the DRAM chips with OLED display panels and NAND flash memory chip.

 Jeff Kim and Kevin Kim states About OLED display

“Inflexible OLED market, Samsung is the only company to mass-produce and to stand in No. 1 position in both OLED smartphone and  panel markets,”

Till now we listen to the word OLED.

  • It is an emergency display technology.
  • In many markets, it became a mainstream display technology.
  • It enables the display panels that offer the best image quality and free design, which can be made flexible and transparent.
  • In all mobile applications, LCD displays are fast replaced with OLEDs. For that Samsung invested billions of dollars for OLED research and production facilities.
  • OLED is a display technology. That offers rich color, high contrast, deep blacks, wide viewing angle.

Due you got a doubt

 Difference between OLED, LED, and LCD screens

iPhone X

As we are familiar with LED (light-emitting diode).

But, many of them think LCD (light crystal display) and LED both are the same.

Tv or smartphone whatever you use had an LCD just, LED is labeled.

LED is just a lighting source, not the display itself.


Now look at the difference

  • LED and LCD screens use backlight for illuminating their pixels, but OLED uses their own light.
  • The OLED display is controlled using a pixel-by-pixel basis. not possible in LED

Second maker for OLED displays to Apple

iPhone X

LG, the display is the second maker of OLED displays, recently in a quality test conducted by apple LG’s OLED panels passed in it.

So, up to now, I mean till the iPhone X series that Samsung only enjoyed the monopoly and deals to provide 100 million OLED displays.

If a deal moved to LG, the upcoming series launches using LG Display OLED screens.


This is the brief information about the companies which provide screens used for iPhone series.
