A number of technical challenges are emerging in the preparation of Apple's completely bezel-free iPhone, due to which the technology will not be introduced to the market until 2026. Users around the world are waiting for this "zero bezel" iPhone, but according to reports, Apple will still need more time to turn this dream into a reality.
Apple's vision: unique and unique design
Apple has worked for several years on reducing the edges (bezels) in iPhone models so that the screen becomes completely "borderless". But Apple's goal is different from current curved display designs such as Samsung's smartphones or Xiaomi's "quad-curved waterfall display". Apple wants a design that not only extends the screen to the full edges but also avoids problems such as the "magnifying glass effect", which is usually seen at the edges of curved screens.
Apple is eyeing a unique and elegant design that would seamlessly extend the screen to the edges while maintaining the flat screen and angled edges of the current iPhone. Experts have described the design as “pebble-like” and “cutting-edge.”
Technical Challenges and Obstacles
Apple is working with Samsung Display and LG Display on this revolutionary design. But the project faces several major technical hurdles, especially in adopting two key technologies:
- Thin Film Encapsulation (TFE): This technology is used to protect OLED displays from moisture and other environmental influences.
- Optical Clear Adhesive (OCA): Transparent adhesive films are needed to adhere to curved edges.
Along with these technologies, Apple also needs to ensure that the design provides adequate space for key iPhone components such as antennas and other sensors.
In particular, OCA technology remains the biggest hurdle for Apple. Current adhesives distort the display images at the edges, which is called "sideview distortion." Additionally, the edge design needs to be improved to protect it from drops or shocks.
2026 timeline and reasons for the delay
Apple initially planned to mass-produce the screen so that it could be part of the iPhone 18, which is due to launch in 2026. But experts say that if that were possible, these negotiations between Apple and its display partners should have been completed by now.
According to recent reports, these negotiations with Samsung and LG Display are still ongoing. This means that the technology will still need a lot of time to develop and finalize, and it is likely that the zero-bezel iPhone will not be introduced until after 2026.
Possible future for consumers
Despite the delay of Apple's bezel-free technology, the project is an example of Apple's commitment and innovation. Once this technology is complete, it will set a new standard in the smartphone industry. Consumers will have to wait a little longer, but this step by Apple will be seen as another success in terms of its brilliant and unique designs.

Apple's "single slab of glass" iPhone: Not possible in iPhone 18
Apple's former design chief Jony Ive has long described the "holy grail" of iPhone design as a "single slab of glass." That meant a phone with just the screen on the front, with no bezels visible. But according to a new report, Apple's goal doesn't seem to be coming true with the iPhone 18 in 2026.
"Single slab of glass" vision
Although Jony Ive is no longer at Apple, his dream is still a big goal for Apple. The company is working on creating a phone that looks like a "single slab of glass." When viewed from the front, all you see is the screen, with no bezels at all.
The launch of the iPhone X in 2017 was the first major step in this direction, but progress has been gradual since then. The bezels have been reduced in width, but they are still noticeable.
To completely eliminate the bezels, a curved screen would be needed that extends all the way to the sides of the phone. The Apple Watch offers this type of design, where the bezels are hidden under curved glass. But Apple's goal for the iPhone is to make the edges of the screen functional, meaning that every part of the screen is usable.
Samsung introduced curved screens on the sides in its Galaxy Edge series, but those designs featured prominent edges at the top and bottom (forehead and chin). What Apple wants is a uniform design on all four sides, where there is a full screen on each side.
According to Korean media "The Elk", Apple wanted to introduce a zero-bezel design in at least one iPhone 18 model by 2026. But Samsung and LG Display, which are Apple's display suppliers, are having difficulty meeting this goal.
Samsung and LG are developing zero-bezel OLED screens at Apple's behest, but experts say the technology is unlikely to be completed by 2026. An industry official said:
"If Apple wants to launch a zero-bezel OLED iPhone in 2026, we should have completed the technical discussions by now, but the discussions are still ongoing."
Key technical challenges
This goal is technically achievable for Apple, but there are still practical issues that need to be resolved:
- Waterproofing: Waterproofing the joint between the curved screen and the phone's body.
- Magnifying glass effect: Eliminating the "lens-like effect" seen at the edges of the curved screen.
- Antenna performance: Ensuring that the antennas work fully.
- Edge durability: Protecting the curved edges from damage from shocks and drops.
The camera placement issue
Apple had planned to include a punch-hole camera in a zero-bezel iPhone by 2026, as the technology for hiding the camera under the display would not meet Apple's standards by then. But Apple's long-term goal is to hide the camera under the screen as well.
Conclusion
Apple's "single slab of glass" vision would be a revolutionary step in smartphone design, but the project is being delayed due to current technical challenges. The dream of a zero-bezel iPhone in 2026 does not seem to be coming true, but Apple's continued innovation and efforts could make this goal possible in the future.
