LTPO and LIPO are two entirely different technologies used in the process of display manufacturing and we have already seen many brands using these.
So how are they different from each other? Don’t know? We’ll help you out.
LTPO and LIPO Displays – Differences and Purpose
LTPO stands for ‘Low Temperature Polycrystalline Oxide, and it is a backplane technology that is used in OLED displays, whereas LIPO which stands for Low Injection Pressure Overmolding is a packaging technology. Thus, while the two are used in displays, their purpose is entirely different.
Firstly about the LTPO technology, it is used to enable the device to support variable refresh rate, thereby improving its power efficiency. Both LTPS (Low-Temperature Polycrystalline Silicon) and IGZO (Indium Gallium Zinc Oxide) transistors are equipped within LTPO displays, and this combination of two types of transistors provides it with the capability to run at high and low refresh rates from as low as 1Hz to 120+Hz depending on the required task. Usually, most of the major flagship smartphones that are released now in the market feature LTPO displays.
Regarding LIPO displays, it makes use of a liquid polymer and allows the display to get perfectly sealed to the frame. As liquid polymer is only applied across the edges, using this technology helps to achieve reduced bezels around the display, thereby offering a full screen or all screen experience. To note, Apple’s Watch 7 series was the first to feature this display technology and following which, we have also seen it being used in certain models of the iPhone 15 series as well as in the Xiaomi 15 series. Just to add, Meizu is also another brand that has made use of the LIPO technology.
