Samsung Tests 7-Inch FMM-Free OLED to Rival LG Tech
Samsung Display is accelerating development of its proprietary Micro Patterned OLED technology to produce displays without fine metal masks. The company is currently testing a 7-inch prototype targeted at phones and wearables, directly challenging LG Display's competing effort.
Ditching the mask to boost brightness and efficiency
Traditional OLED production relies on fine metal masks to deposit organic light-emitting materials onto substrates. While dependable, the physical structure of the mask limits pixel aperture, meaning less surface area actually emits light.
Samsung's Micro Patterned OLED (MPO) eliminates that physical barrier entirely. By shifting to a maskless deposition process, the panels increase the active emissive area of each pixel. Devices can achieve significantly higher peak brightness at identical power draws, or maintain standard luminance levels while consuming noticeably less battery.
Samsung MPO Prototype: Specifications and Timeline
| Spec | Detail |
|---|---|
| Panel Type | FMM-free OLED (Micro Patterned OLED) |
| Prototype Size | 7 inches |
| Development Start | March 2026 |
| Target Completion | Late 2026 to early 2027 |
| Target Devices | Smartphones and smartwatches |
Samsung vs LG: Diverging size strategies for FMM-free OLED
According to industry reporting from The Elec, Samsung began development on its MPO hardware in March 2026. The initial target was to complete prototype development by late 2026, though that milestone might extend into early 2027.
The standout detail is screen size. Samsung is piloting a 7-inch panel clearly intended for smartphones and smartwatches, a contrast to PC manufacturers experimenting with conventional screens like the Lenovo IdeaPad Vibe launches early at $799 price point. Meanwhile, LG Display's rival process—branded as FLiPP (FMM-Less innovative Pixel Patterning)—targets IT-sized displays, prioritizing laptops and external monitors. Neither display manufacturer plans to adapt the technique for full-sized television panels in the near term.
| Manufacturer | Technology Name | Initial Form Factor | Target Devices |
|---|---|---|---|
| Samsung Display | MPO (Micro Patterned OLED) | 7-inch prototype | Smartphones, Smartwatches |
| LG Display | FLiPP | Medium-format panels | Laptops, PC Monitors |
Samsung's decision to target the 7-inch footprint makes strategic sense. Yield rates for maskless deposition are historically difficult over larger surface areas. By tackling mobile screens first, Samsung can absorb production variances while delivering the battery-saving gains that mobile shoppers demand, leaving LG to battle the harder economics of laptop panels.
Availability and pricing
Consumers in the US, UK, and Europe should not expect commercial devices with MPO screens immediately. Samsung's current run involves internal prototypes, meaning commercial availability in flagship Galaxy phones or wearable devices will likely occur in late 2027 or 2028 at the earliest.
Production costs are expected to drop over time once mask fabrication overhead is eliminated, though initial retail pricing for early devices incorporating the panels has not been announced.
The race to drop fine metal masks will reshape mobile display benchmarks over the next two hardware cycles. If Samsung stabilizes MPO production first, portable consumer screens will see dramatic gains in outdoor legibility without the standard battery penalty.
Frequently asked questions
What is FMM-free OLED technology?
It is an OLED manufacturing method that removes the traditional fine metal mask during deposition, allowing pixels to fill more surface area for improved brightness and lower power usage.
When will Samsung release phones with MPO displays?
Samsung expects to wrap initial prototype work between late 2026 and early 2027, making mass-market consumer phone rollouts unlikely before late 2027 or 2028.
