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 produced in 2018 - 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 starting to adopt 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 - the flexible 5.8" 1125x2436 OLED (made by SDC) used by Apple's iPhone Xs is considered the best mobile display ever produced.

Royole announces new foldable OLED displays with much improved specifications

Chinese OLED developer Royole announced its next-generation (3rd-Gen) fully flexible OLED displays, which it refers to as "Cicada Wing". Royole says that these new displays deliver significant improvements over its previous generation displays. The new displays have a material stack of over 100 layers.

Cicada Wing displays, compared to Royole's 2nd-Gen flexible OLEDs, offer 5X higher contrast, 50% higher brightness, 20% faster response time and a better color shift. It also offers a low brightness decay (Royole says it is 3.5X better then competing foldable OLEDs).

DSCC: 577 million OLED panels shipped in 2019, generating $27.9 billion

DSCC says that OLED panel revenues in Q4 2019 reached $8.1 billion, down 2% from Q3 2019 and pretty much the same as in Q4 2018. In terms of units, DSCC says that in Q4 2019 124 million smartphone panels were shipped, 31 million wearable panels and 998,000 TV panels.

OLED panel revenue (2016-2019, DSCC)

Smartphone revenues in Q4 2019 were down 2% from Q4 2018 (due to lower average sales price for both rigid and flexible panels, the number of panels actually increased 4%), and revenues for TVs were up 30% (to $752 million). Smartwatches remain the 3rd largest market for OLED panels, and experienced strong growth in 2019, but it seems as if the growth may have plateaued (in Q4 the revenues were down 7% from last year).

We now list BOE's 5.99" 1080x2160 flexible smartphone AMOLED display at the OLED marketplace

We are happy to announce that we now list a new panel at the OLED Marketplace - a BOE 5.99" 1080x2160 flexible AMOLED display with a flexible touch panel.

This is a high-end smartphone display (but can be used for other applications as well) that is now in production (at BOE's B7 line in Chengdu). Check out more information over at the OLED Marketplace, or contact us now.

LG's iPhone display orders propel its OLED smartphone market share to over 10% in Q4 2019

Towards the end of 2019 LG Display started to supply Apple with 6.1" film-touch OLED flexible displays for its 2020 iPhone, and IHS Markit now says that these shipments propelled LGD's OLED smartphone market share to 10.8% in Q4 2019 (up from only 2.1% in Q3 2019).

In fact LGD now says that mobile OLED revenues make up for 36% of its total revenues in Q4 - which is higher than its OLED TV revenues for the first time ever.

iFixit offers lower-cost LCD replacements for broken iPhone X and Xs OLED screens

Apple's latest flagship iPhone displays all use OLED screens, and Apple is charging a hefty fee for a screen replacement - $280 if you do not have AppleCare. Another option is to buy the OLED screen from a vendor - at a lower cost, and perform the replacement yourself.

One such vendor is iFixit - and the screens still cost around $185 for the iPhone Xs and $155 for the iPhone X. iFixit is now offering a lower cost alternative - replace the OLED with an LCD display, which costs around $100 less than the fancier OLED option.

Samsung Display announced new high-efficiency smartphone AMOLED displays

Samsung Display announced that it developed a new AMOLED smartphone display, optimized for 5G smartphones, that features a reduction of 15% in its power consumption compared to SDC's previous OLEDs. The new display also features the lowest blue-light emission in the industry - 6.5%.

Samsung did not explain how it managed to achieve the new reduction in power consumption - this is likely to be the result of new OLED materials. Samsung also does not explain how exactly these new OLEDs are optimized for 5G smartphones exactly - except for saying that these new displays are an excellent choice due to their high image quality, low power consumption and eye-protective functionality (low blue light).

Motorola's foldable Razr 2019 is a week old - and reports of screen damage continue

In early February Motorola started shipping its $1,500 foldable OLED phone, the Razr 2019 - with its 6.2" 2142x876 (21:9) inside-foldable AMOLED display, produced by BOE. Initial reports suggested that the screen feels fragile - even more so than the screen of the Galaxy Fold.

Phone Radar now reports that only a week after getting the device, the plastic display is peeling off at the fold. iFixit tested the device, and scored it 1 out of 10 in terms of durability and fixability - and a simulated test suggested a failure at the hinge mechanism.

Is TCL developing an expanding-sliding OLED smartphone?

CNet reports that TCL was supposed to demonstrate a novel smartphone design next week (at the cancelled MWC event) that uses an "expandable" sliding OLED display. The idea is basically the same as in the first crop of foldable OLEDs - provide a phone that can open up to a tablet-size device:

Apparently TCL was supposed to show a working demonstration. Such a design will likely require a screen that is folded in two places or some sort of rollable display - which is possible but more difficult to actually commercialize compared to a screen that folds inwardly or outwardly in a single position.
