Samsung reportedly demonstrated new OLED technologies - including polarizer-free OLEDs and 1,200 PPI VR displays

Mar 23, 2017

According to the Korea Herald, Samsung Electronics demonstrated several new display technologies in a private room during the Mobile World Congress last month. All of these technologies are expected to enter production within the next year or two, according to the source quoted by the report.

1,200 PPI AMOLED for VR

The report claims that Samsung demonstrated a high-resolution AMOLED panel for VR applications. The AMOLED on display featured a 1,200 PPI - much higher than Samsung's current highest density displays which are 577 PPI. Samsung's aim is to reach 1,500 PPI which will greatly enhance the VR experience.

SDC 806 PPI VR OLED at SID 2016

In November 2016 Sunic Systems announced that it developed an plane-source evaporation-FMM based AMOLED production process that can reach very high densities. The 100um mask announced in November can achieve a PPI of 1,500. This may be the system that Samsung is now testing. Sunic says that eventually this technology will enable even 2,250 PPI.

AUO starts shipping a new 1.3" on-cell touch 240x240 AMOLED display

Digitimes: Samsung and LG aim to reduce their reliance on foreign organic material producers

Mar 22, 2017

Digitimes Researcher states that currently Samsung Display and LG Display both rely on imported organic materials used in OLED production, but the two Korean makers aim to decrease this reliance. Both companies are buying stakes in companies outside of Korea (for example Samsung's Novaled acquisition and Sun Fine Chem investment) in order to obtain patents and move production in house, mostly at LG Chem and Samsung SDI.

The polyimide used as a substrate in flexible OLEDs, for example, is produced by Japanese Ube Industries - and used by both LG and samsung. Several organic materials used in the OLED stack are produced by Universal Display (PHOLED emitters), Idemitsu Kosan, Dow Chemical and Merck. Both companies use glass mostly from Corning and high-temperature thin film for the back-end processing from 3M.
