    Mobile screen technology at a glance should be divided into two general categories, LCD and OLED, where in LCD displays the image and lighting sections are separate, but in OLED panels we encounter integrated units of light and image. Apart from these two general groups, there are other influential elements behind the scenes of display technology that have a direct impact on the user experience. LTPO is one of these that is currently only available on a few devices such as the Apple Watch 6 Series and Galaxy The S21 Ultra is from Samsung and plays an important role in energy consumption. Read more about LTPO technology and its benefits.

    Refresh rates above 60 Hz have become commonplace in smartphones and their logo can be found even in the mid-range and cheaper models on the market. These screens, despite providing a smooth experience of moving between different menus and programs that support this feature, also require higher power consumption than normal 60 Hz panels; This energy consumption is even higher in the presence of high-density QHD panels, and naturally the battery power of such devices is significantly reduced. Thus, at first glance, you have to choose between better battery consumption or a higher screen refresh rate. LTPO, however, gives a different answer to this question. LTPO, or low-temperature polycrystalline oxide, is a type of backplane technology developed by Apple; The technology, first introduced in the Apple Watch 4 Series, made its importance a year later in the Apple Watch 5 Series, where the ever-bright display capability of this model came true without high power consumption.

    Backplane technology in a display determines the type of material and layout of transistors called TFTs. In other words, the backplane consists of a series of transistors whose task is to turn specific pixels on and off at a certain time and is a determining factor in matters such as screen resolution, refresh rate and power consumption. The backplane type is not necessarily related to the technology of making LCD and OLED panels, but occasionally due to some considerations such as higher price in models such as LTPO, it is (at least for now) used only in fully advanced OLEDs.

In LTPO, however, LTPS TFTs and oxidized TFTs (based on IGZO or Indium Gallium Zinc Oxide) combine to create displays with variable refresh rates; The refresh rate in these panels varies depending on the content and practically leads to lower energy consumption. LTPO can thus be described as a revolutionary technology in energy consumption, as it no longer requires an additional component between the display controller and the central graphics unit (GPU) to automatically change the refresh rate.

    Apple The new display uses the Apple Watch 5 Series, where the screen update rate automatically changes between 1 and 60 Hz depending on the content being played, and for example, the Always-on display does not require a high refresh rate. Page content is updated every second. Thus, it goes without saying that the energy consumption of the clock in this technology will be much more efficient than before.

    Although LTPO technology should be called an Apple technology (with specific and registered patents), other companies in turn A similar definition of the technology, including the combination of polycrystalline silicon oxide (abbreviated HOP) from Samsung, was first introduced in the Galaxy Note20 Ultra, but later in the Galaxy S21 Ultra also achieved higher degrees of consumption reduction.

    Another relatively new product introduced with this feature is the OnePlus 9 Pro, which according to the manufacturer, allows you to change the screen refresh rate from 1 to 120 Hz depending on the content. The refresh rate of the OnePlus 9 Pro display automatically adjusts to 24 frames per second when watching a 24-frame video, and viewing a still image is enough to reduce this rate to just 1 Hz. With the exit from the gallery and the beginning of the rotation between the menus, the refresh rate increases again to its maximum of 120 Hz. The Oppo Find X3 and Find X3 Pro with 6.7-inch 1440 x 3216 pixel screens are among the few other phones equipped with this technology.

    Looking at the above, the most important feature of LTPO technology is its lower power consumption by changing the screen refresh rate, a feature that is especially appealing in the flagship category with large screens with high refresh rates and a certain battery volume. It seems absolutely necessary. Despite offering LTPO for the Apple Watch 5 Series and Apple Watch Series 6, Apple has not yet used this technology in its iPhones due to the lack of refresh rates above 60 Hz, but there are numerous and unconfirmed reports of the use of LTPO in the iPhone 13 Series. The presence of LTPO in Apple iPhones, apart from helping to learn more about this technology, will undoubtedly play a positive role in alleviating one of Apple's oldest problems, namely the low battery life of the company's iPhones.
