Phone Display Test Results

Display Testing Methodology:

We begin by measuring each device’s maximum brightness.The 20% APL (average picture level) test uses a white rectangle that covers 20% of the screen, with the rest remaining black, while the 100% APL test uses a fully white image. Since modern OLED screens adjust their brightness depending on the image, the 20% APL test is a more realistic measure of their actual performance.

The Bright Min results show how dim the phone can get. A lower value here is better as the phone will be more comfortable to use in dark environments.

The Color Temperature test uses a reference of 6500K, which is considered standard daylight color temperature. A higher value indicates colder whites, while lower ones mean warmer tones.

We also measure the display’s Gamma, which shows how smoothly the screen transitions from dark to bright area. A value of 2.2 is considered ideal for a natural look with balanced contrast.

Finally, the Delta E measurements show how precisely the display reproduces colors (the RGBCMY score) and neutrals (Grayscale). In both cases, lower values mean better color fidelity.

Display Testing Conditions:

Devices are tested using their default display settings (color profile, resolution and refresh rate). The display quality is measured using professional-grade color calibration equipment under controlled lighting conditions.

All tests are conducted on new devices, running the latest available firmware at the time of testing.

Note: Real-world brightness and color performance may vary depending on ambient lighting, display wear over time, and software updates.
