In the world of cell phones, new technologies are continuously appearing with the goal of improving the user experience, and one of the most recent is LTPO displays. Last year, several phones began implementing these features, and they’re here to stay now more than ever. As a result, it’s crucial to understand what these screens are and how they might assist you.
OLED and IPS LCD screens dominate the market today, but LTPO screens are finding their way into the high-end market as they provide considerable advantages in terms of energy efficiency, as we’ll see in more detail below.
Everything You Need to Know About LTPO Displays
LTPO displays, also known as “low-temperature polycrystalline oxide” panels, offer greater potential for savings in terms of both electricity and heat compared to displays utilizing other technologies, such as those described above. This is because they are able to change their refresh rate in real-time, which helps the autonomy of the mobile or any other device that uses it to be greater than what can be obtained with conventional TFT, LTPS, LCD, IPS LCD, and OLED screens in any of their presentations. This is due to the fact that they are capable of varying their refresh rate in real-time.
Apple was the first company to create and patent this technology, which is why other companies immediately began working to produce their own versions of LTPO technology under various brand names in order to profit freely from Apple’s labor. It has been referred to as “HOP” (Hybrid-Oxide and Polycrystalline Silicon) in the case of Samsung, for example, but it is based on the same principle as LTPO technology.
Low-Temperature Polycrystalline Silicon (LTPS) displays are said to have been the precursor of LTPO (Low-Temperature Polycrystalline Organic) displays. This is due to the fact that manufacturers have combined some of the transistors that are used in LTPS and TFT panels with new ones made of different materials (indium, gallium, zinc, and oxygen, abbreviated as IGZO), in order to achieve a lower energy impact on the device itself. LTPS and TFT panels are both types of liquid crystal display panels.
On the other hand, since this technology is fully compatible with OLED, it is very uncommon to come across mobile devices that feature displays that are either LTPO OLED or, as in the case of the OnePlus 10 Pro, “LTPO2 Fluid AMOLED.” And it is for this reason that, as we have mentioned, manufacturers frequently name their displays in a variety of ways and at their leisure, which is directly related to the marketing strategies they implement when presenting and releasing their goods in a fashionable manner.
The Benefits of Using an LTPO Display on a SmartPhone
- To recap, the primary benefit of LTPO displays is their ability to save energy. As a result, these panels use less battery power than other types of screens because they can lower their refresh rate to an appropriate number of frames per second (Hz) depending on how they are being used. The refresh rate may be increased instantaneously, which is not possible with traditional panels, which have a fixed refresh rate.
- However, what does Hz mean when it comes to refreshing rates?? When a screen refresh rate is 1Hz, for example, the image on the screen will be changed once per minute; as a result of this, the mobile device’s battery consumption will be significantly reduced; as a result, it will be able to run for longer periods of time. This means that if it has a refresh rate of 120 Hz, the image on the screen will be updated 120 times per minute. A greater understanding of how screen picture refreshes affect battery usage may be gained by looking at this example.
- Refresh rates can vary greatly depending on the phone and the manufacturer’s specifications, since some screens have a minimum refresh rate of just 10 Hz, while others have a maximum of 90 or 120 Hz; this relies on the specifications of the phone and what the manufacturer has set for it.
- Although LTPO displays can already achieve 144 Hz on mobile devices, their maximum refresh rate is currently 1 Hz in order to conserve battery life and enhance battery life, at the time of publishing of this article. Another incentive to choose a smartphone with an LTPO screen is that these panels often have high refresh rates starting at 120 Hz; this provides a smooth and speedy user experience.
- Many famous smartphones have recently introduced LTPO panels, however for now the Samsung Galaxy S22, iPhone 13 Pro and Max, OnePlus 9 and 10, realme GT2, Oppo FindX3 Pro, iQOO 9 Pro, Xiaomi 12 Pro, and the Google Pixel 6 Pro are the only ones that have these displays available to consumers. Because these and other high-end phones have this sort of screen, there are no lower or mid-range phones with these screens.
Assuming they do make it to lower-cost smartphones, we can only hope that these panels will become commonplace in the near future.
