OLED Smartphones

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.

Samsung says that the "business environment deteriorated significantly in the fourth quarter due to weak demand amid a global economic slowdown". SDC's mobile AMOLED panel business earning declined, as demand for smartphones fell, but its large-area panel business seen a smaller loss as it is increasing sales of QD-OLED panels.

Today it is possible to repair a smartphone display and replace the screen - and there are companies (mostly independent outlets) that offer lower cost displays - which could refurbished ones, aftermarket imports - or even lower cost alternatives produced by other makers. If the FTC approves Samsung's request, these will not be available anymore, and only original Samsung AMOLED displays will be allowed.

Amorphyx Q&A about champion performance in IGZO TFT for OLED Smartphone applications

This is a sponsored post by Amorphyx, where display industry consultant Ian Hendy has interviewed Amorphyx's CEO John Brewer

Q: Can you start by telling us a little about what Amorphyx does, John?

Amorphyx has several fundamentally new technology platforms that provide for TFT performance improvements in three areas: (1) Switching speeds, with options to move to the Tera-Hz range ultimately, (2) Power, where the IGZO AMeTFT can achieve even lower power performance than today’s LTPO OLED Pro Motion displays and better refresh range, and (3) Small transistor size.

Our technology platforms are lower cost than the alternatives, and move from amorphous and crystalline semiconductor approaches, to devices based on different effects that do not have a semiconductor at all, yet can still drive a display, drive current, deliver grey scale and switch very fast. Or they can operate a flex IC at higher clock speeds than known today.

For now, our main commercial focus is on IGZO AMeTFT which is fundamentally a potential replacement transistor for LTPS or LTPO used in modern OLED phones and has the capability to replace more highly compensated LTPO circuits in modern Smartphone displays due to enhanced stability.

Samsung shows a 2,000 nits smartphone AMOLED display, brands it as UDR

Samsung Display is showing a new OLED smartphone display, that achieves a brightness of 2,000 nits and an improved dynamic range. Samsung brands this as a UDR 2000 display.

The new OLED display was verified by UL (Underwriter Laboratories), an independent testing and validation firm, for the UDR 2000 certification. Samsung's AMOLED have already achieved 2,000 nits (for example in the iPhone 14 Pro screen), but this new display offers a higher dynamic range.

Visionox signs an agreement with the government of Hefei to build its $1.6 billion flexible OLED module fab

In May 2022, Visionox announced plans to build a 11 billion Yuan ($1.6 billion USD) flexible and foldable OLED module production line, in Hefei. Yesterday the company signed the formal agreement with the local government and kickstarted the project.

According to reports from China, the new factory will have a yearly capacity of around 26 million modules in sizes ranging from 6-inch to 12-inch, although the company says it will also produce wearable OLED display modules at this fab, so there will be smaller sizes as well.
