DxOMark test shows OLEDs more likely to cause eye fatigue than LCDs
Recently, DxOMark released its new research article about the reasons for the flickering of popular science smartphone displays and whether it will damage eyesight or not. The report also suggests that OLED screens are more likely to cause eye fatigue than LCDs.
According to DxOMark, flicker refers to the continuous on and off of the screen and the human eye’s iris expands and contracts according to the brightness change. This automatic physiological response explains why our eyes feel tired after watching the screen for a long time as the eyes are always in high-intensity work.
However, the OLED and LCD screen’s light source power supply method determines that these two technologies will have flicker effects. Usually, the flicker effect of OLED panels is more obvious than the LCD displays.
DxOMark pointed out that the PWM (Pulse Width Modulation) frequency range of OLED screens is 50 to 500Hz and the frequency of LCD is higher than 1000Hz, while the human eye is only sensitive to flicker at 250Hz, so OLED displays are more likely to cause eye fatigue than LCDs.
Aside from this, DxOMark has also revealed the test results of the refresh rate and PWM frequency of smartphones from various brands. Among them, Samsung’s Galaxy S20 Ultra 5G that supports 60Hz refresh rate OLED panels has a PWM frequency as low as 241Hz, which is very easy to cause eye fatigue.
On the other hand, the PWM frequency of the Xiaomi Mi 10T Pro mobile phone with a 144Hz refresh rate LCD panel is as high as 2360Hz, which is much higher than the human eye’s sensitivity to flicker. If you want to read the full research, you can check it out by clicking here.

Samsung is reportedly working on the development of the Galaxy S24 FE. Earlier this year, the company released the Galaxy S24 flagships, which are selling well globally. Now, the company has started work on its next budget flagship, with a release expected later this year.
GalaxyClub reports that Samsung is developing the Galaxy S24 FE with the R12 codename. The codename aligns with Samsung’s previous releases as the S20 FE was codenamed R8, the S21 FE was R9, the S23 FE was R11, and the R11 (S22 FE) was in development but hasn’t been released.
It was reported that Samsung might launch the S24 FE in the summer. As the development starts late, the release may be pushed to later this year, as testing and production aren’t finalized yet. The latest report also has no other details than the device’s codename.
Galaxy S23 FE has the hardware specs of the S22 series, however, the S24 FE might bring the latest. If it happens, we might see a price hike in the next budget flagship. New Galaxy AI features are also expected to debut with the S24 FE, before the S25 series launch next year.
Samsung is also working on an affordable Galaxy Z Fold 6, which would be the first Fan Edition foldable. Judging from the 2023 release strategy, it’s expected that the Galaxy S24 FE might launch alongside the Galaxy Z Fold FE, new FE tablets.

The US variant of Samsung Galaxy Z Flip 6 will be equipped with a Snapdragon 8 Gen 3 processor. There were reports that Samsung may expand the Exynos chipset to its foldable lineup, which doesn’t seem to be happening, at least in the United States.
Recently, Samsung Galaxy Z Flip 6 US variant was spotted on Geekbench with Snapdragon chip. It isn’t surprising as the company is following its conventional chipset strategy. We expect that it will be the same chipset used in the Galaxy S24 Ultra, the Snapdragon 8 Gen 3 for Galaxy.
The Flip 6 smartphone scored 15084 points on Geekbench’s GPU test. Due to its foldable form factor, the device may miss a Galaxy S24-like larger cooling technology. Still, its impressive 15000+ points in the GPU test indicates that Samsung has greatly optimized the software.
The company still has three months remaining in the launch event. More performance improvements will likely be achieved before the Unpacked. The South Korean tech giant will likely unveil the next-gen foldable phones in mid-July.
This year, the Galaxy Z Fold 6 Ultra would join the standard Galaxy Z Fold 6 and the Galaxy Z Flip 6. In addition, an affordable variant of Fan Edition branding is also in development. However, the cheaper foldable would miss some pro-grade specs to maintain the price.
