We put the Xiaomi 14 through our rigorous SBMARK Display test suite to measure its performance across four criteria. In the results of this test, we will analyze how it performed in a series of tests and in several common use cases.
Ħarsa ġenerali
Speċifikazzjonijiet ewlenin tal-wiri:
- 6.36 pulzier OLED
- Riżoluzzjoni: 1200 x 2670 pixels, (densità ~ 460 ppi)
- Rata ta 'riħid: 120Hz
Prosperità
- Smooth viewing experience while scrolling the web
- Adapted brightness in low light conditions for photos and web
- Nice color rendering in indoor conditions for the photo
Kontra
- Many discrepancies between frames when watching videos
- Lack of brightness and detail in the indoor lighting environment when viewing photos
- Nuqqas ta 'luminożità u dettalji skuri meta tara vidjows HDR10
- Il-wirja mhix uniformi
The Xiaomi 14 had mixed display performance in our tests, although it offered a very smooth screen experience in all use cases, with consistent performance in touch and video attributes.
The device’s top-scoring attribute was touch, thanks to an impressive average touch-to-display response time of 64 ms.
Even though the Xiaomi 14 provided acceptable video performance, the overall video performance of the device was affected by some instabilities. When watching HDR10 video indoors, the screen lacked sufficient brightness and showed little detail in dark tones, particularly in low-light conditions. Additionally, HDR10 frame-drop handling was poor.
In terms of readability, the Xiaomi 14’s screen handled brightness well, particularly in low light conditions, however, it may be a little lacking in terms of readability in bright light conditions. Xiaomi claims that the device can reach a peak brightness of 3000 nits, but our tests showed that the device reaches 2740 nits, but only for HDR video content. Our experts measured 923 nits under 20,000 lux and just 1490 nits under sunlight on a classic white picture pattern (20% window) in High Brightness mode, lower results than some competitors in this segment. Readability, however, was affected by the screen’s low-frequency time management in default mode (but the device has an anti-flicker function that can limit this phenomenon.) The Xiaomi 14’s screen also lacked brightness and color uniformity.
The Xiaomi 14’s colors were quite good in most lighting conditions when viewing photos, but when tested in true mode, the screen’s color rendition may appear slightly saturated.
Sommarju tat-test
Dwar it-testijiet tal-wiri SBMARK: Għall-punteġġ u l-analiżi, apparat huwa soġġett għal serje ta 'testijiet oġġettivi u perċettivi taħt laboratorju kkontrollat u kundizzjonijiet tal-ħajja reali. L-SBMARK Display Score jqis l-esperjenza ġenerali tal-utent ipprovduta mill-iskrin, meta tqis il-kapaċità tal-ħardwer u l-ottimizzazzjoni tas-softwer. Waqt l-ittestjar jintużaw biss apps tal-vidjow u tar-ritratti installati fil-fabbrika. Aktar dettalji fil-fond dwar kif il-wiri tat-testijiet SBMARK jistgħu jinstabu fl-artiklu "Ħarsa aktar mill-qrib lejn l-Ittestjar tal-Display SBMARK."
It-taqsima li ġejja tiffoka fuq l-elementi ewlenin tal-ittestjar u l-analiżi komprensivi tagħna mwettqa fil-laboratorji SBMARK. Rapporti komprensivi b'evalwazzjonijiet dettaljati tal-prestazzjoni huma disponibbli fuq talba. Biex tordna kopja, ikkuntattjana.
Kif huwa magħmul il-punteġġ tal-leġġibbiltà tal-wiri
Il-leġibbiltà tevalwa l-faċilità u l-kumdità tal-utent biex jara kontenut stazzjonarju, bħal ritratti jew paġna tal-web, fuq il-wiri taħt kundizzjonijiet tad-dawl differenti. Il-kejl tagħna mwettqa fil-laboratorji huwa kkumplimentat minn testijiet u analiżi perċettivi.

SCI tfisser Specular Component Included, li jkejjel kemm ir-riflessjoni mxerrda kif ukoll ir-riflessjoni spekulari. Ir-riflettanza ta 'pjanċa tal-ħġieġ sempliċi hija madwar 4%, filwaqt li tilħaq madwar 6% għal pjanċa tal-plastik. Għalkemm l-ewwel wiċċ ta 'smartphones huwa ħġieġ, ir-riflettanza totali tagħhom (mhux miksija) hija ġeneralment madwar 5% minħabba riflessjonijiet multipli maħluqa mill-munzell ottiku kumpless.
Ir-riflettanza medja hija kkalkulata abbażi tar-riflettanza spettrali fil-medda tal-ispettru viżibbli (ara l-grafika hawn taħt) u s-sensittività spettrali tal-bniedem.
Uniformità
Din il-grafika turi d-distribuzzjoni tal-luminanza madwar il-pannell tal-wiri kollu. L-uniformità titkejjel b'disinn griż ta '20%, b'aħdar qawwi li jindika luminanza ideali. Kulur aħdar jgħajjat imqassam b'mod uniformi madwar l-iskrin jindika li l-luminożità tal-wiri hija uniformi. Kuluri oħra jindikaw telf ta 'uniformità.
Displays teptip għal 2 raġunijiet ewlenin: rata ta 'aġġornament u modulazzjoni tal-wisa' tal-polz. Il-modulazzjoni tal-wisa 'tal-impuls hija teknika ta' modulazzjoni li tiġġenera impulsi ta 'wisa' varjabbli biex tirrappreżenta l-amplitudni ta 'sinjal ta' input analogu. Dan il-kejl huwa importanti għall-kumdità għaliex it-teptip ta 'frekwenza baxxa jista' jiġi pperċepit minn xi individwi u, f'każijiet aktar estremi, jista 'jikkaġuna aċċessjonijiet. Xi esperimenti juru li l-iskumdità tista 'sseħħ aktar ta' spiss. Frekwenza għolja PWM (> 1500 Hz) għandha t-tendenza li tfixkel inqas lill-utenti.
Kif huwa magħmul il-punteġġ tal-kulur tal-wiri
Evalwazzjonijiet tal-kulur huma mwettqa taħt kundizzjonijiet ta 'dawl differenti biex tara kemm l-apparat jimmaniġġa l-kulur mal-madwar tiegħu. L-apparati huma ttestjati b'mudelli ta 'immaġni sRGB u Display-P3. Kemm il-mod fidila kif ukoll il-mod default jintużaw għall-evalwazzjoni tagħna. Il-kejl tagħna mwettqa fil-laboratorji huwa kkumplimentat minn testijiet u analiżi perċettivi.
Circadian action factor is a metric that defines the impact of light on the human sleep cycle. It is the ratio between the light energy that contributes to sleep disturbances (centered around 450 nm, representing blue light) and the light energy that contributes to our perception (covering 400 nm to 700 nm and centered at 550 nm, which is green light). A high circadian action factor means that the ambient light contains strong blue light energy and is likely to affect the body’s sleep cycle, while a low circadian action factor means that the light has weak blue light energy and is less likely to affect sleep patterns.
Kif huwa magħmul il-punteġġ tal-Vidjo Display
L-attribut tal-vidjo jevalwa l-immaniġġjar tal-vidjow Standard Dynamic Range (SDR) u High Dynamic Range (HDR10) f'kundizzjonijiet ta 'ġewwa u ta' dawl baxx. Il-kejl tagħna mwettqa fil-laboratorji huwa kkumplimentat minn testijiet u analiżi perċettivi.

Dawn l-indikaturi jippreżentaw il-perċentwal ta' irregolarità tal-qafas f'video ta' 30 sekonda. Dawn l-irregolaritajiet mhumiex neċessarjament pperċepiti mill-utenti (sakemm ma jkunux kollha bl-istess timestamp) iżda huma indikatur tal-prestazzjoni.
Kif huwa magħmul il-punteġġ Display Touch
Aħna nevalwaw l-attributi tal-mess f'ħafna tipi ta' kontenut fejn il-mess huwa kritiku u jeħtieġ imġieba differenti bħal logħob (mess mgħaġġel u ħinijiet ta' rispons), web (scrolling tal-paġna bla xkiel), u immaġini (navigazzjoni preċiża u bla xkiel minn immaġni għal immaġni). oħrajn).
