Samsung S21 Ultra features new OLED power-efficient Display

Samsung OLED Display

When Samsung launched its product galaxy S21 ultra. Samsung informed that the device’s screen will support refresh rates of 120Hz at both full HD and Quad HD resolutions. But it didn’t inform that the Samsung Galaxy S21 ultra is the first Samsung display that features a low-power OLED display.

Samsung says that the OLED display consumes 16% much less power. Because of a “just-developed organic material” that means electrons flow faster and more easily through the Samsung S21 Ultra display’s organic layer.

Samsung simply explains this technology as OLED panels will create brighter light with less power. Thus improving battery life. Generally, A smartphone display is one of the elements which requires the most power. So, by designing a display that consumes less power it can have a great impact on the overall battery life of the device. Samsung S21 ultra uses an OLED display that can last longer than a full day.

How Samsung S21 Ultra Display works

An OLED display doesn’t need any additional light source but instead produces vibrant colors by running an electric current directly through an exclusive set of self-luminous organic materials. Because of this reason, the efficiency of organic materials is very important in defining an OLED display’s performance. Also, it includes its color range, high-dynamic-range imaging (HDR), and power consumption.

Head of the mobile display sales executive Jeeho Baek said “The current demand of display technologies are looking for lower power consumption to enable features such as greater resolution, faster display driving, and larger screens.

He further added that ” Samsung display is directly contracting with many of its users to improve performance of their newest products that are building upon industry-leading expertise in material technology which is progressing rapidly for a long time.

Samsung displays use novel organic material through it achieved its sharp increase in luminous efficiency. By making electrons flow faster and easily between the display’s organic layer. In simple terms, OLED panels can produce brighter light with less power. Thus improving battery lifetime for 5G smartphone users. Thus using an OLED display in Samsung S21 Ultra can significantly improve battery usage time.

Samsung OLED display transferring its technological resources into securing “super-gap” competitiveness in the form of more effective organic display materials. For that Samsung is collaborating with a number of global material companies, and increasing its influence in the smartphone display field over the past decade. Currently, Samsung display holds nearly 5000 patents worldwide which involve using organic materials for display. Along with that Samsung has applied for more than 370 patents regarding OLED organic materials in the past three years.

Samsung Rumored to supply LPTO OLED for next iPhones

If reports are accurate, Samsung displays are going to be the exclusive supplier for the apple for organic light-emitting diode (OLED) panels. These panels will be used in the iPhones next models.

As per reports both of the iPhone 13 models will be using low-temperature polycrystalline oxide (LTPO) thin-film transistors (TFT) OLED panels all are made by the Samsung Display. Apple’s iPhone 13 will come in four models. All of them are going to use OLED panels. The top two models of iPhone 13 will use LPTO OLED. These displays can support a 120Hz refresh rate. Allowing faster display updates in a second. 

This year LG Display won’t be able to supply its LPTO OLED to Apple for iPhones, but LG is planning to supply them in the year 2022. Still, it is in the development stage we can say. Last year Samsung display was the only supplier for iPhone 12 series on cell OLED panels. The 5.1-inch iPhone 12 Mini and 6.7-inch iPhone 12 Pro Max used this method. All of the iPhone 13 models are going to use on-cell OLEDs.

Samsung’s Galaxy Note 20 Ultra also used LTPO display panels as HOP panels.

Samsung confirmed that the Samsung S21 Ultra uses an LPTO OLED display, but it is not the first time Samsung phones feature this type of display. Last year The Elec reported that Samsung’s Galaxy Note 20 Ultra also used LTPO display panels. Samsung calls this technology Adaptive Frequency or hybrid oxide and polycrystalline silicon (HOP).

However, as per the latest announcements, the Samsung S21 Ultra is the first to use the more power-efficient panels. It suggests that Samsung display has further improved its technology compared to last year.

Samsung Display is looking forward to transferring some of its A3 line to Asan for LPTO TFT. The Asan line has nearly a production capacity of 105,000 sheets per month in that around 60,000 sheets will be transferred to LPTO TFT.

Compared to conventional OLED panels, LPTO TFT panels production takes around 2 weeks longer. LTPO TFT combines an oxide process in TFT production with the previous low-temperature polycrystalline silicon (LTPS) process.

Before using LPTO OLED displays in smartphones, LPTO displays have been used in smartwatches. According to Elec, the Apple Watch Series 4 features an LPTO display that was produced by LG. Whereas Samsung Galaxy Watch Active 2 also used an LPTO display produced by Samsung display.


 In a press release, the Samsung Galaxy S21 ultra is the first Samsung display that features a new power-efficient OLED display. OLED panels can create brighter light while consuming less power. Because of a “just developed organic material” that means electrons flow faster and more easily between the display’s organic layer.
