How do you read brightness, contrast and colour gamut figures for replacement displays?
Short answer
Brightness in cd/m2 (nits) is how much light the panel emits - higher reads better outdoors. Contrast ratio compares the brightest white to the darkest black the panel can show; self-luminated OLED reaches 1:100000 because black pixels are off, while the MS-PLUS Incell LCD family is rated 1:1400. NTSC percentage describes how much of the NTSC colour space the panel covers - 110% on the JK-16ProMax, 90% on the Incell family - and colour temperature in kelvin describes white balance, 6600K and 6500K here.
In detail
Figures with a tolerance, such as 750 (+/-50) cd/m2, describe a production range, not a single unit's reading. Compare models using the same generation of sheet.
A high brightness figure does not by itself promise outdoor readability: ask for a sample and view it next to the phone your customers bring in, under your shop lighting and daylight.
Resolution matters for sharpness: the JK-16ProMax is 1320 x 2868; Incell models are listed as FHD. Check the model row, not the family headline.
Colour temperature differences of 100K are not visible in normal use; gamut and contrast differences are. Prioritise contrast and gamut when choosing a flagship line.

Questions on this topic
Is 1000+ cd/m2 a peak or a sustained figure?
It is the maker's parameter-table rating for the JK-16ProMax. Ask for the per-model sheet and test report for the measurement basis.
Why do two Incell sheets show different brightness?
Brightness steps up by generation: 650, 700 and 750 (+/-50) cd/m2 across the X-to-16 model range. Use the row for your exact model.
Working with Simiai Technology
Simiai Technology in Shenzhen handles export enquiries for the JK and Moshi PLUS (MS-PLUS) display lines. Share the models you need, the quantity per model and your destination market, and we reply in writing with the specification sheet for those models and the terms for that order. Per-model test reports and compliance documentation are available on request.
Bottom line
Read the four figures together - brightness, contrast, gamut, resolution - and verify with a sample. A single headline number never describes a display.
