Pros

  • Adapted luminance in outdoor and indoor conditions
  • Smooth touch interaction in every use case and quick response time to touch
  • Accurate color rendering

Cons

  • Poor  HDR video experience in low-light environments in terms of brightness, dark details, and colors
  • Unnatural tone rendering appearance under sunlight
  • Relatively strong reflections

The OnePlus 13 display demonstrated an overall good performance, especially in readability and touch.

The device’s luminance was well-suited in indoor and outdoor situations despite an unnatural tone rendering under sunlight (with the High Brightness Mode activated). The relatively strong reflections impacted outdoor performances, adding a color cast when viewing content. Reading comfort was enhanced thanks to the screen’s lack of flicker.

Using faithful mode, color rendering was accurate overall, but colors visibly shifted when the screen was held at a 25° angle.

The device’s weakest performance was in HDR and SDR video rendering in low-light conditions because of poor brightness, contrast, and color results. However, in indoor lighting conditions, the device rendered HDR videos with adequate luminance and contrast, providing a generally good experience.

Touch interactions on the screen had a fast response time and were smooth and accurate, despite some occasional unintended touches.

Test summary

About DXOMARK Display tests: For scoring and analysis, a device undergoes a series of objective and perceptual tests in controlled lab and real-life conditions. The DXOMARK Display score takes into account the overall user experience the screen provides, considering the hardware capacity and the software tuning. In testing, only factory-installed video and photo apps are used.  More in-depth details about how DXOMARK tests displays are available in the article “A closer look at DXOMARK Display testing.”

The following section focuses on the key elements of our exhaustive tests and analyses performed in DXOMARK laboratories. Full reports with detailed performance evaluations are available upon request. To order a copy, please contact us.

How Display Readability score is composed

Readability evaluates the user’s ease and comfort of viewing still content, such as photos or a web page, on the display under different lighting conditions. Our measurements run in the labs are completed by perceptual testing and analysis.

Luminance under various lighting conditions
This graph shows the screen luminance in environments that range from total darkness to outdoor conditions. In our labs, the indoor environment (250 lux to 830 lux) simulates the artificial and natural lighting conditions commonly seen in homes (with medium diffusion); the outdoor environment (from 20,000 lux) replicates a situation with highly diffused light.
Contrast under various lighting conditions
This graph shows the screen’s contrast levels in lighting environments that range from total darkness to outdoor conditions. In our labs, the indoor environment (250 lux to 830 lux) simulates the artificial and natural lighting conditions commonly seen in homes (with medium diffusion); the outdoor environment (from 20,000 lux) replicates a situation with highly diffused light.
Photo EOTF
The Electro-Optical Transfer Function (EOTF) defines how bits are converted into luminance out of the display. Gray levels (horizontal axis) represent the different shades from pure white (100% gray level) to pitch black (0% gray level). The standard for still images follows a 2.2 gamma. The flatter the curves, the harder it is to perceive differences between consecutive shades. This phenomenon is more frequent under intensive lighting conditions (20,000 lux) in the low gray level regions.

Luminance vs Viewing Angle
This graph presents how the luminance drops as viewing angles increase.

SCI stands for Specular Component Included, which measures both the diffuse reflection and the specular reflection. Reflection from a simple glass sheet is around 4%, while it reaches about 6% for a plastic sheet. Although smartphones’ first surface is made of glass, their total reflection (without coating) is usually around 5% due to multiple reflections created by the complex optical stack.
Average reflectance is computed based on the spectral reflectance in the visible spectrum range (see graph below) and human spectral sensitivity.
Reflectance (SCI)
Wavelength (horizontal axis) defines light color, but also our capacity to see it; for example, UV is a very low wavelength that the human eye cannot see; Infrared is a high wavelength that the human eye also cannot see). White light is composed of all wavelengths between 400 nm and 700 nm, i.e. the range the human eye can see. Measurements above show the reflection of the devices within the visible spectrum range (400 nm to 700 nm).

Uniformity
This graph shows the distribution of luminance throughout the entire display panel. Uniformity is measured with a 20% gray pattern, with bright green indicating ideal luminance. An evenly spread-out bright green color on the screen indicates that the display’s brightness is uniform. Other colors indicate a loss of uniformity.

Displays flicker for 2 main reasons: refresh rate and Pulse Width Modulation. Pulse width modulation is a modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. This measurement is important for comfort because flickering at low frequencies can be perceived by some individuals, and in the most extreme cases, can induce seizures. Some experiments show that discomfort can appear at a higher frequency. A high PWM frequency (>1500 Hz) tends to be less disturbing for users.
Temporal Light Modulation
This graph represents the frequencies of lighting variation; the highest peak gives the most important modulation. The combination of a low frequency and a high peak is susceptible to inducing eye fatigue.

How Display Color score is composed

Color evaluations are performed in different lighting conditions to see how well the device manages color with the surrounding environment. Devices are tested with sRGB and Display-P3 image patterns. Both faithful mode and default mode are used for our evaluation. Our measurements run in the labs are completed by perceptual testing & analysis.
