What is an OLED display?

An OLED display uses a new technology called OLED (Organic Light Emitting Diodes). OLED screens are brighter, more efficient, thinner and feature better refresh rates and contrast than LCD or Plasma.

OLEDs are made by placing thin films of organic (carbon based) materials between two conductors. When an electrical current is applied, a bright light is emitted. Since the OLED materials emit light, a backlight is not required (unlike LCDs).

OLEDs in mobile phones

Mobile phones that boast OLED screens are rapidly becoming more prevalent, with over 500 million AMOLED screens annually - mostly to satisfy demand from mobile phones. Samsung has been using AMOLEDs in its high-end phones for many years, and most phone makers are also adopting OLED displays (including Apple, LG, Xiaomi, Huawei, Oppo, Vivo, Lenovo, Motorola, and others).

OLED displays are advancing quickly, and today smartphone AMOLED displays outperform LCDs in all parameters - except the price which is still at a premium.

Based on DisplayMate's extensive lab tests and measurements the OnePlus 12 delivers excellent display performance - and has earned the company's highest overall display assessment rating and highest display performance grade of A+. The display matches or breaks 18 different display quality records. some of these display records records include the highest peak display brightess (it reaches 2,675 nits for Low APL), the lowest screen reflectance (4%), the highestabsolute color accuracy (visually indistinguishable from perfect), and the largest native color gamut.

UBI: Samsung to delay the introduction its first blue phosphorescent AMOLEDs to the second half of 2025

Universal Display is progressing with its blue PHOLED material, and earlier this month the company said it is on track to introduce the new material commercially in 2024. During a company seminar, UBI's Daejeong Yoon updated that according to their latest information, Samsung Display has decided to adopt a blue phosphorescence material in the second half of 2025 - a year later than expected.

Samsung is calling the new material stack B1, and it says that the new stack will increase the efficiency of its OLED device by more than 65% (which seems to be rather too much, maybe it means 65% of the power consumption of the current stack). UBI says that the blue OLED still suffers from low lifetime - the lifetime of the blue PHOLED stack is only 55% of the lifetime of its current fluorescence-blue stack, but regardless of that the company will introduce it commercially due to the power consumption efficiency.

Apple finally approves BOE as an iPhone 15 AMOLED supplier, will order 2 million diplays in 2023

BOE has been trying to be accepted into Apple's supply chain for their latest iPhone devices for many years, but has so far succeeded only in getting small orders for aftermarket panels. In March it was reported that BOE is developing panels for Apple, but in September it was reported that Apple decided to cancel all of its panned orders for BOE's iPhone 15 display OLED panels due to technical issues, and has moved all these orders to Samsung Display.

Now it is reported in Korean media that BOE has been finally approved, and the Chinese-based OLED maker will supply 2 million panels for Apple - or only about 3% of its total OLED supply in 2023. Obviously BOE hopes to gain more orders in 2024.

Samsung to bring AMOLED displays to its lowest-cost phone lineup

According to reports from Korea, Samsung Electronics has decided to adopt an AMOLED displays in its upcoming budget phone, the Galaxy A15. This will be the lowest cost Samsung phone to ever sport an OLED display.

Most of Samsung's entry-level phones use an LCD, but it seems that as prices of OLED panels continue to drop, Samsung is introducing its OLED into a wider range of phones. In fact it is said that Samsung's production cost of a rigid OLED is currently lower than the production cost of an equivalent LCD display. The A15 will use a 6.4" rigid (glass-based) panel, and the phone itself will cost around $270 when it launches next year, for the 5G variant.

DSCC: the OLED industry's capacity still far outstrips demand, recovery will not be easy

DSCC shared their estimation about display fab utilization (LCD and OLEDs), with some interesting comments. The slowdown in the industry, according to DSCC, is effecting all display makers, but the slowdown in demand for OLEDs is more severe and persistent. The industry is starting to recover, but this is a bumpy ride as the total capacity still far outstrips demand, and DSCC sees a slowdown in Q4 2023.

DSCC says that the slowdown for large-screen displays bottomed out towards the end of 2022, the slowdown in mobile devices only hit bottom in early 2023. There is still a weak demand for rigid OLEDs, mostly because of the lower demand for smartphones - but also because China-based flexible OLED makers are lowering prices to make them more competitive with glass-based OLEDs.

DSCC: smartphone OLED revenues to decline 11% in 2023, growth to resume in 2024

DSCC says that OLED smartphone shipments will total 585 million units in 2023, a 0.3% decline from 2023 in terms of shipments. Revenues will total $29 billion, a 11% decline from 2023. The soft demand for smartphones is due to a slow Chinese market, high inventories in the first half of 2023 and the global macroeconomic environment.

For flexible OLEDs, DSCC expects a 14% growth in 2023 (shipments) and a 9% decline in revenues - as average sale price has dropped 20%. The industry saw aggressive price cuts by Chinese phone makers - to the point where a flexible OLED made in China is cheaper than a rigid OLED made in Korea (by SDC). The market share of flexible OLED smartphones will reach 75% in 2023 out of the total OLED smartphone market.
