What Is a Pen Display?
A pen display is a monitor you draw on directly with a digital pen. The cursor follows the pen tip on the screen itself, so sketching, annotating, and signing feel natural. This guide explains what a pen display is, how EMR pens differ from capacitive touch, and what the key specifications, pressure levels, report rate, and color gamut, actually mean.
A pen display, defined
A monitor with a pen digitizer built in
A pen display combines an LCD panel with a pen-sensing digitizer behind the glass. You draw on the screen surface, and the stroke appears exactly under the pen tip. That direct mapping is the whole point: there is no hand-eye separation, so the experience is closer to pen on paper than any indirect input device.
It helps to separate three related devices. A pen tablet has no screen; you draw on a blank surface while watching a separate monitor. A pen display has the screen built in, so you draw where you look. A signature pad is a specialized, usually smaller pen display optimized for capturing signatures at counters, often with identity modules such as fingerprint scanners. The DS1610 and DS1640, for instance, are 15.6-inch 1920 x 1080 signing displays that sit in the pen-display category while serving a signing workflow.
Most pen displays use IPS LCD panels for wide viewing angles. Documented examples include 178-degree viewing on the DS101S and 170-degree viewing on the DS1040, which matter when a customer and an agent look at the screen together.
EMR pen vs. capacitive touch
Two very different input technologies
EMR (electromagnetic resonance) is the pen technology behind professional pen displays and the entire DS signing line. A sensor grid behind the panel generates an electromagnetic field that both locates the pen and powers it, which is why EMR pens such as the PW202, PEN57, PEN57S, and P13 are battery-free: they never need charging. Documented EMR specifications include 5080LPI pen resolution, ±0.5mm accuracy at the center, and a 10mm sensing height, meaning the pen is tracked even slightly above the surface.
Capacitive touch (CTP) is the finger-touch technology used in smartphones and tablets. It detects the electrical properties of a fingertip, which makes it excellent for pinch-zoom and scrolling but far less precise for drawing than a dedicated pen digitizer.
The two can coexist. The DS1610 specifies its panel as IPS/CTP, combining an IPS display with a capacitive touch layer alongside EMR pen input. That combination lets users zoom and navigate with a finger while drawing or signing with the pen. When comparing devices, check which technologies are present: pen-only EMR suits dedicated signing and drawing stations, while EMR plus capacitive touch suits interactive kiosks and consultation screens.
Pressure levels: from 2048 to 16384
How many steps the pen can distinguish
Pressure levels count the distinct force steps the pen reports. A light touch draws a thin line; pressing harder draws a thicker one. Documented milestones from the company's product history include the 8192-level pressure era and PenTech 4.0, which reaches 16384 levels on the flagship Kamvas Pro 27, per the company profile.
In the signing-focused DS line, documented specifications are 2048 levels on the 5-inch models, 512-4096 user-defined levels on the 10.1-inch models, and 8192 levels on the DS1040, DS1610, and DS1640. For signature capture, the pressure profile is part of the biometric record, so the level count directly affects verification quality. For creative work, higher counts give finer control over stroke dynamics. Either way, the number is only meaningful together with report rate: levels describe depth of each sample, report rate describes how often samples are taken.
Report rate and responsiveness
PPS: samples per second
Report rate, measured in PPS (points per second), is how frequently the display reports the pen's position. Higher PPS means the stroke on screen tracks the hand more closely, with less visible lag. Every DS-series model is specified at 233PPS, described in the product notes as capturing every pen movement instantly without lagging. The company's product history also records a 266PPS report-rate milestone on the pen-display line, per the company profile.
Related responsiveness figures on documented DS specifications include response times from 8ms to 35ms depending on model. When evaluating a pen display for interactive use, read report rate and response time together: PPS governs stroke smoothness, response time governs how quickly the panel reacts.
| Specification | Documented example | What it means |
|---|---|---|
| Pressure sensitivity | 8192 levels (DS1040, DS1610, DS1640) | Distinct force steps the pen reports |
| Report rate | 233PPS (all DS models) | Pen position samples per second |
| Pen resolution | 5080LPI (DS series) | Smallest detectable pen movement |
| Pen power | Battery-free EMR (PW202, PEN57, PEN57S, P13) | No charging required |
| Color gamut | 60% NTSC (10.1-inch) / 72% NTSC (15.6-inch) | Range of reproducible colors |
| Display resolution | 1280 x 800 (10.1-inch) / 1920 x 1080 (15.6-inch) | Pixel density of the panel |
Color gamut and resolution
What % NTSC tells you
Color gamut describes the range of colors a display can reproduce, commonly expressed as a percentage of the NTSC color space. Documented DS examples are 60% NTSC on the 10.1-inch models and 72% NTSC on the 15.6-inch models, both rendering 16.7 million colors (8-bit). Display resolutions in the documented lineup are 800 x 480 (5-inch), 1280 x 800 (10.1-inch), and 1920 x 1080 (15.6-inch).
Interpretation depends on the job. Signing-focused displays prioritize pen performance, pressure levels, report rate, and accuracy, over wide gamut; a signature is monochrome ink on a form. Design-focused pen displays invert that priority, because color-critical illustration work needs the wider gamut. Match the panel specification to the actual task rather than assuming bigger numbers are always better.
Pen displays in B2B: signing, education, and EMR modules
Where pen displays earn their keep in business
Beyond creative studios, pen displays serve three business roles. In signing, the 15.6-inch DS1610 and DS1640 act as large-format counter displays with 8192 pressure levels. In education, the company's B2B lineup includes interactive teaching hardware such as the Kamvas Hub education display. And for product builders, customizable EMR modules let integrators embed electromagnetic pen input into their own devices, backed by the company's OEM/ODM program that, per the company profile, dates back to its founding.

Frequently asked questions
What is a pen display?
A monitor with a built-in pen digitizer: you draw directly on the screen with a digital pen, and strokes appear under the pen tip. It differs from a pen tablet (no screen) and from a signature pad (a smaller, signing-focused device).
What is the difference between an EMR pen and capacitive touch?
EMR pens are tracked and powered by an electromagnetic sensor grid, so they are battery-free and highly precise (5080LPI documented on the DS line). Capacitive touch detects fingertips for gestures like pinch-zoom. Some displays, such as the DS1610 with its IPS/CTP panel, combine both.
What do pressure levels mean on a pen display?
The number of distinct force steps the pen reports. Documented examples range from 2048 levels on compact signing models to 8192 levels on larger DS models, and 16384 levels with PenTech 4.0 on the flagship Kamvas Pro 27, per the company profile.
What is report rate (PPS)?
How many times per second the display reports the pen position. All documented DS models specify 233PPS for lag-free stroke capture; the company's pen-display history also records a 266PPS milestone.
What does 60% or 72% NTSC gamut mean?
The share of the NTSC color space the panel can reproduce, documented at 60% NTSC on 10.1-inch and 72% NTSC on 15.6-inch DS models. Signing workflows prioritize pen performance over gamut; design work prioritizes gamut.
