Recently, China Taier Lab awarded the 5G digital mobile phone OnePlus 10 Pro (model: NE2210) mobile phone of Shenzhen OnePlus Technology Co., Ltd. with five-star adaptive display refresh rate performance. Certificate. This is the first certificate after the launch of the “Mobile Terminal Adaptive Display Refresh Rate Performance Evaluation Scheme (Regular Scenario & Game Scenario)” by China Tell Labs.
Mobile Terminal Adaptive Display Refresh Rate Performance Evaluation Scheme (Conventional Scenarios & Game Scenarios) is mainly to test and verify the five dimensions of non-game scenarios, game scenarios, power consumption experience, basic display performance, and low blue light performance of mobile phone products. , and score various test results, and finally get the corresponding star according to the score. Products with a five-star rating have an excellent adaptive display refresh rate performance experience.
After evaluation, the OnePlus 10 Pro model mobile phone has an excellent performance in five dimensions: non-game scene, game scene, power consumption experience, basic display performance, and low blue light performance, reaching the evaluation level of a “five-star product with adaptive display refresh rate performance” Require.
Interpretation of the attached evaluation items
Non-game scenarios
- The non-game scene evaluation items mainly include minimum display refresh rate, maximum display refresh rate, adaptive display refresh rate, frequency up speed, down frequency speed, frequency conversion flicker, low-frequency flicker and low-frequency smear, etc. Use these items to evaluate the performance experience of adaptive screen refresh rate.
Game scene
- The game scene selects the training ground of shooting games. The main evaluation is to find target delay, mirror opening delay, aiming delay, hit feedback delay, comprehensive delay, temperature rise limit frame delay, display delay and viewing angle rotation. The lower the delay, the better the time correspondence of visual and tactile manipulation, and the better the interactive experience.
Power consumption experience
- It mainly evaluates the power loss within a unit of time. The lower the power loss, the less obvious the perception of the power consumption experience, and the longer the time, the more energy-saving the user perceives the game.
Basic display performance
- It reflects the hardcore strength of the screen visual experience. It mainly measures the basic optical performance indicators such as screen brightness, contrast, uniformity, color, resolution and clarity, which corresponds to the subjective feeling of the user when using it.
Low blue light performance
- The low blue light performance is used to verify the ability of the mobile phone screen in terms of software anti-blue light and hardware anti-blue light, and comprehensively examine the blue light radiation of the screen itself and the anti-blue light performance under the blessing of software. At the same time, in response to the color cast problem of the screen caused by the anti-blue light function, the evaluation of color is added, and the screen has a balance between low blue light and color performance.
Interpretation of the attached evaluation data
Non-game scenarios:
It can achieve not only a lower display refresh rate of 1Hz but also a higher refresh rate of 120Hz, which provides necessary conditions for taking into account the display effect and energy-saving needs. The display refresh rate no longer relies on coarse-grained simple scene recognition (such as application list, content type, user operation, etc.), but can be switched adaptively according to the software frame rate. Not only can it match simple scenes (such as 120Hz for sliding operation, 30/60Hz for video playback, and 1Hz for still images), it can also quickly match some complex scenes, which can achieve both display effects and energy-saving needs.
Upscaling speed and downclocking speed: It only takes 8.3ms to increase from 1Hz to 120Hz, which satisfies the high brushing fluency, and only 67.3ms to decrease from 120Hz to 1Hz, so as to achieve the purpose of saving power consumption. The screen can quickly adapt to the current usage scenario, adjust the refresh rate to the current application state, and make the experience online every moment.
In the variable frequency flicker performance, the display brightness and chromaticity fluctuation between different refresh frequencies are small. For the flicker caused by screen refresh, it has a lower low-frequency flicker. At low frequencies, through the evaluation of the smear brightness ratio and smear color difference, the results show that the prototype has less smear.
Game scene:
It is found that the target delay, mirror opening delay, aiming delay, hit feedback delay and their comprehensive delay values are small, the temperature rise limit frame delay and display delay value is also small, and the picture when the viewing angle is rotated is basically free from freezes. , the time correspondence of comprehensive visual and tactile manipulations is better, so the interactive experience is better.
The evaluation items in the game test scene, the delay test results are excellent. Among them, after the overclocking response function is turned on, the delay performance of the display delay is improved by more than 70% compared with the traditional use of a fixed display refresh rate (overclocking response function is turned off). The experience continues to be online.
Power consumption experience:
The power loss per unit time is low, and the perception of power consumption experience is not obvious.
Basic display performance:
The screen has a resolution of 525 PPI and 3216 * 1440 and has good color performance. Its color gamut coverage (DCI-P3 color gamut space) and color reproduction accuracy are high, the light and dark details are expressive, and the uniformity effect is good.
Low blue light performance:
The screen has excellent software and hardware anti-blue light capabilities, and it has achieved a very good balance in low blue light and color accuracy performance.
