Apple's iPhone Duo has exceeded pre-order expectations in major markets, prompting optimism among display chip suppliers for increased investment in foldable devices. Industry sources believe the iPhone Duo's success could bolster other smartphone makers' confidence in foldables, thereby expanding the market for OLED touch and display driver integration (TDDI). While cost currently hinders OLED TDDI adoption in conventional flagship smartphones, it is deemed a technical necessity for foldables, offering chipmakers a path to higher shipments. Apple's rumored touchscreen MacBook is also seen as a potential driver for investment in notebook displays, creating opportunities for more sophisticated components. Rival manufacturers are anticipated to adopt similar display technologies in response to Apple's new products, benefiting companies beyond Apple's direct supply chain. This potential growth arrives amidst a period of subdued consumer demand in the latter half of 2026. Furthermore, strong demand for the iPhone Duo could offset softer sales of the iPhone 18 Pro. The positive reception of the iPhone Duo is a significant development for the display and smartphone industry. It highlights a potential shift towards foldable technology and integrated display solutions.
