What's different about the Samsung Galaxy S5 LTE-A WQHD Super AMOLED display?

The Galaxy S5 LTE-A's processor and 3 GB of RAM will help with the device's performance, but how much better is that praised WQHD Super AMOLED panel?
July 7, 2014

The Samsung Galaxy S5 LTE-A was recently announced in South Korea as a higher-end smartphone to succeed the Galaxy S5. Aside from the faster LTE speeds, the device comes with a series of improvements, including a Snapdragon 805 processor, 3 GB of RAM and a WQHD (2560x1440p) Super AMOLED display.

Now, we know the processor and 3 GB of RAM will help with the device’s stunning performance, but how much better is that praised WQHD Super AMOLED panel? Samsung is trying to make its new display’s advantages very clear with its latest blog post.

Definition and PPI

Of course, one of the advantages of the improved display is definition. WQHD resolution is nothing to scoff at, especially when viewed in a 5.1-inch display. This amounts to 577 PPI (pixels per inch), which is a substantial improvement over the Full HD Galaxy S5’s 432 PPI.

The 2560x1440p resolution amounts to a total of 3,686,400 pixels, which was unheard of in any smartphone not so long ago. This makes for crisper text and much more details in image and video (given that they offer the same resolution or higher). Below you will find a comparison given to us by Samsung.


The difference in image detail is quite substantial when you look deeper into the image, like the feathers in the bird. While 1080p is already stunning, there seems to be a significant difference in that WQHD resolution, after all.

Is this all that we were hoping for, though? This is, after all, information we already knew. The trick is really all on the fact this is a Super AMOLED display.

Super AMOLED and Samsung’s tricks

The first thing you will notice about Super AMOLED displays are those amazingly vibrant colors and stunning deep blacks. Also, AMOLED displays are, by nature, much more power-efficient, but that 2560x1440p resolution is still not easy on battery life. This is why Samsung is using some ingenious techniques to keep the device alive for longer.

For starters, Samsung created a new type of OLED technology with more power-efficient organic material. This means the display is naturally better than regular AMOLED panels. In addition, Samsung has added RAM to the Display Driver IC, which is one of the elements that allows for images to be displayed. This forces the display to only use power when the screen is activated.

Lastly, Samsung changed the color composition in the user interface. Colors were re-adjusted to create a more energy-efficient experience without giving up the vibrant and saturated AMOLED colors we all know and love.

We have yet to see how well these improvements work. We must wonder if this is better than what LG is doing with the G3. We are still not sure if the Samsung Galaxy S5 LTE-A will ever make it outside of Korea, though.
