Technological advancements in backlight display is expected to drive the mobile phone LED market demand over the forecast timeline. The Organic Light-Emitting Diode (OLED) are brighter than LEDs, increases the battery life and have better response time for sensing the finger touch. Currently, the OLEDs are quiet costlier than LCD and LED displays and the costs are expected to reduce over the years owing to the economies of the scale.
OLED technologies are currently used in high end smartphones with some mobile phones using AMOLED display. For instance, OnePlus’ 5 smartphone feature a 5.5” FHD AMOLED display. Similar display technology is used in Oppo R11, Moto Z2 Play, Samsung Galaxy S8, J3 Pro and Vivo Xplay 6.
As LED flash has become the standard specification in smartphones, many LED manufacturers have entered into this potential industry. Some manufacturers are integrating front LED flash to satisfy the increasing night vision selfie demand. Lumileds is the oldest manufacturer of LED flash followed by Osram and Everlight. Samsung has also started to make flash LEDs for its smartphone consumption. Currently, the industry is swarmed with the entrance of Chinese manufacturers thereby not leaving the industry solely to Taiwanese and international players.
