This year’s apple watch series 6 is expected to have OLED screens like the previous models, but future models are likely to be Apple products with micro LED display technology, although it will take three to four years. According to reports, EPISTAR is working on building a factory to produce micro LED displays for future Apple products.
according to Li Bingjie, chairman of Jingyuan optoelectronics, smart watches will be the first major application of micro led, and may be applied in batches in 3-4 years.
Li Bingjie pointed out that wafer optics has overcome the difficulties of mass production transfer and other micro led technologies, and is expected to achieve reliable production capacity in 2-3 years, and launch terminal market application in 3-4 years.
it is reported that Apple will invest $330 million in Taiwan’s Micro led plant to produce displays for future iPhone, iPad, macbook and other devices. For PCB substrate with minimum size of 50-100 μ m, micro led with size of 20-50 μ m is too small, so glass substrate is adopted. Taiwan LCD panel maker Youda optoelectronics will provide glass substrates for displays, and wafer optics is said to be focusing on improving the yield of micro led epitaxy and reducing the cost of large-scale transfer.
micro LED screens have several advantages over LCD and OLED displays, including thinner and more energy-saving. For example, the power consumption of micro LED screen is only one tenth of that of LCD display, and the color saturation is close to that of OLED. In addition, micro LEDs can support higher brightness, higher dynamic range and wider color gamut, while achieving faster update speed, wider viewing angle and lower power consumption.
due to the difficulty in the development of micro LED technology, it is expected that early design will rely on mini LED which is between traditional LED and micro LED technology. However, according to previous reports, apple still considers micro LED technology “the top priority.”.
Apple has been testing prototype Apple watch models with micro LED displays since 2017, according to reports. Although early rumors suggested that the apple watch with micro LED displays could be launched as early as 2020, a whistleblower said in May that this year’s apple watch series 6 will use the same OLED display as the previous model, which poured cold water on this prediction.
there is a precedent for the new screen technology to appear on the apple watch. When it was launched in 2014, the apple watch adopted OLED screen, and then the technology was transferred to the iPhone x three years later.
