Resolution and brightness get most of the attention when sourcing a display for creative or stylus-input work, but two other specs — color gamut and cover glass compatibility — decide whether the finished product actually works the way it's supposed to. Here's what else to check.
Color gamut: what NTSC 72% actually covers
Color gamut describes how much of the visible color range a display can reproduce, most commonly expressed as a percentage of the NTSC reference gamut. 72% NTSC is a solid working gamut for general creative use — sketching, note-taking, general design review — but it's worth knowing its limits:
- It's narrower than the wide-gamut panels used in color-critical photo and video grading monitors
- For most drawing-pad and general creative applications, 72% NTSC is genuinely sufficient — the gap only matters if your specific workflow depends on precise color matching against a professional reference
- If color accuracy is a hard requirement rather than a nice-to-have, confirm the gamut spec explicitly rather than assuming a "good enough" panel covers it
Cover glass compatibility: the spec that's easy to miss
A display panel's optical and touch performance is validated against a specific cover glass thickness — deviate from that and you risk touch accuracy issues, optical artifacts (like a visible air gap or reduced contrast), or stylus-tracking inconsistencies that weren't present in the panel's own testing.
This particular panel is specified for 0.4T (0.4mm) cover glass. If your mechanical design calls for a thicker protective layer — for extra durability, for example — that mismatch needs to be resolved before finalizing your enclosure, either by adjusting the cover glass spec or confirming with your supplier whether the panel's touch/stylus system tolerates the difference.

What to confirm before finalizing your mechanical design
- Whether your application genuinely needs wider color gamut than 72% NTSC, or whether this is sufficient
- Your cover glass thickness plan, checked explicitly against the panel's 0.4T specification
- Stylus and touch controller compatibility with both the panel and the specific cover glass you plan to use
