Samsung’s New Display Makes the S21 Ultra More Efficient
It’s safe to say that OLED displays are the gold standard for smartphones these days. What you may not know is that some OLED panels are better than others, and the Galaxy S21 Ultra may have the best yet.
The best may be subjective in some ways – but the device’s display is definitely the most energy efficient. In fact, Samsung has developed a new ultra-low power OLED display for the new phone that cuts energy consumption by up to 16%.
The way Samsung did this is a little technical. OLED displays generally do not require backlighting like LCD screens. Instead, each individual pixel is made from an organic carbon-based material that lights up when electricity is applied. OLED displays are made up of a number of layers that serve different purposes. The essence of the new OLED display technology is that Samsung has found a way how electrons can flow faster between these layers while creating a brighter light at the same time.
The power savings are put to good use as 5G phones can use slightly more power than non-5G phones, while other things, like more powerful chipsets, can hoard power as well.
It’s important to note that the new display technology is only available for the Galaxy S21 Ultra – not the standard Galaxy S21 and Galaxy S21 +. All three devices offer a refresh rate of up to 120 Hz. The Galaxy S21 Ultra, however, has a resolution of 1,440p. While the standard Galaxy S21 and S21 + have refresh rates between 48 Hz and 120 Hz, the Galaxy S21 Ultra can reach up to 10 Hz, which also helps to save energy.
Samsung has long been a leader in display technology, and it looks like it will continue to do so in the future. According to the company, it holds 5,000 patents that use organic materials for displays. Hopefully, this new technology will be available for lower-priced phones in the next few years, or at least the entire Galaxy S22 series next year.
