Uniformity of backlighting, calibration results, dead pixel check

To test the uniformity of the backlighting, screen brightness was set to 160 cd/m². The test was carried out on a calibrated profile.

Luminance uniformity was good. As you can see, the illumination intensity decreases as you move away from the center. The maximum subsidence is observed on the left. When analyzing the black field, we found no obvious bleeding. Of course, the presence or absence of "highlights" may differ between different units of this model, but in this case, we can only report a good result for the test sample.

Viewing angles, glow-effect, and pulse width modulation

The viewing angles are great (typical for OLED). OLED panels have greater off-axis image quality than LCDs, although they are not flawless. The light output remains very constant, and the detail remains consistent. We scarcely noticed anything when we moved off-center in the material. There’s no glow effect.

Calibration results

After calibration, the accuracy of the panel’s color rendition significantly improved. DeltaE deviations reached 0.19 on average (norm - 1.5) and 0.52 on maximum deviation (norm - 4). The measured vs assumed target whitepoint DeltaE*00 is now 0.22, much lower than the recommended 1.

Dead pixel check

On inspection, we found no dead or stuck pixels.
