TapTechNews August 26th news, according to the display backplane research released by TrendForce today, OLED has become the mainstream display technology of smart phones, promoting the penetration rate of mid-to-high-end backplane technologies such as LTPS and LTPO in the smart phone market in 2024 to nearly 57%; In 2025, due to improved yield and effective cost control, the penetration rate is expected to challenge 60%..
It is reported that currently most flagship phones adopt the low-temperature polycrystalline oxide LTPO (Low Temperature Polycrystalline Oxide) backplane technology, and in the larger-sized folding phones, the effect of different refresh rates for picture segmentation can be achieved through LTPO, taking into account both the multi-tasking mode of the picture and the energy-saving effect. LTPO technology adds an oxide semiconductor on the basis of LTPS to optimize the display performance, including improving the problem of leakage current when driving the picture and adjusting the screen refresh rate according to the display content. However, since the production process of LTPO requires stacking more layers, its manufacturing process is complex and the manufacturing cost is also higher than that of LTPS..
TrendForce stated that the oxide (Oxide) semiconductor backplane technology currently commonly used in the smart phone screen mainly uses materials such as zinc oxide (ZnO) or indium gallium oxide (IGZO), and this technology is also often used in high-end displays such as Apple's iPad and Macbook series and other medium-sized products. The leakage current of Oxide is low, which will be beneficial to the application in transparent displays in the future.
TapTechNews learned from the report that in addition to OLED occupying a dominant position in the display market of smart phones, AMOLED panels are accelerating the development to other IT markets, including medium-sized displays such as tablet computers and laptops. According to the research, when IT equipment brand customers choose the matching backplane technology, they will comprehensively consider the display effect, energy consumption, cost and product positioning. Currently, when panel manufacturers are preparing new capacity for large-generation AMOLED panels, it is expected that they will give priority to using high-end backplane technologies such as Oxide or LTPO to meet the requirements of different brands for specifications.
