Workspace
The exact size of the active area of a tablet (or screen in a graphic display) in width and height. In general, it is more of a reference than a practically significant parameter: when choosing a traditional graphics tablet, there is often enough information about the format (see above), and for displays, primarily the diagonal (see above) and aspect ratio (see below) are of practical importance . However, the exact dimensions can also be useful in fact: for example, you can determine the aspect ratio from them (for classic tablets, this parameter is often not indicated).
Control keys
The number of control keys provided in the design of the tablet.
Each of these keys is responsible for a specific function, while the set of these functions can be configured: in some models they can be selected manually, in others the functionality of the keys changes automatically, depending on the currently active application. Anyway, additional keys allow the user to perform various actions without looking up from the tablet — this can be very convenient in the midst of the work process, when you don’t want to change the pen to the mouse again or reach for the keyboard. And the more control keys — so, respectively, more additional actions can be performed using the tablet. On the other hand, with relatively simple tasks, the abundance of additional buttons can hinder and confuse the user rather than help.
The most modest modern tablets provide
up to 5 control keys ; the most popular option is
from 6 to 10 keys, and in advanced models this number can reach
15 or even
more.
Scroll wheel
A wheel for scrolling content on the screen, similar to that used in modern computer mice. A similar wheel is placed on the side or top of the graphics tablet case. It is used for quick navigation through graphical applications, documents or web pages. At the same time, the scroll wheel has expanded functionality - by pressing it you can perform certain commands or gestures such as zooming an image, scrolling horizontally, etc.
Touch ring
The device has
a touch ring for quick control of popular parameters. By simply moving your finger around the ring, you can zoom and scroll in graphics applications, switch between layers, change brush size, rotate the canvas, etc. Note that the touch ring can have several operating modes, and a physical button in the center of the circle is often responsible for switching between them. In advanced devices, the ring can be reprogrammed for certain actions, and even sensitivity (scrolling speed) can be adjusted.
Compatibility
Full-fledged and mobile operating systems with which the device can interact normally. Specific compatibility options may be:
-Windows. The vast majority of graphics tablets are designed to work together with desktop computers and laptops running Windows. At the same time, it is important to clarify the supported OS versions - in modern realities, these are Windows 10 and Windows 11.
—
MacOS. The ability of the device to work with Apple computer equipment that uses the proprietary desktop operating system macOS. First of all, these are iMac desktops and MacBook laptops. This technique has software and hardware features that significantly distinguish it from other types of PCs and laptops, so such compatibility for graphics tablets is specified separately.
-
ChromeOS. ChromeOS is a software product from Google originally created for laptops. The key feature of Chromebooks is their close integration with web services, and in general they are positioned as the most inexpensive and accessible laptops.
- Linux. Initially, the Linux platform was designed mainly for professional programmers and IT enthusiasts. For the average user, such a system can be quite difficult to learn and use. However, a number of graphics tablet models are compatible with this OS.
-
Android. Compatibility of the device with
...portable gadgets running Android OS (primarily smartphones and tablets). This involves using mobile versions of applications to create and process graphics.
- iOS. The ability to work with mobile applications for creating and processing graphics, implemented when using Apple smartphones running the iOS operating system.Resolution
The number of horizontal and vertical pixels from which an image is formed on the graphic display screen (see “Type”). Higher resolution results in sharper, more detailed images for precise graphics work. However, high resolution affects the cost of the graphics display.
As for specific resolutions, models with
Full HD screens predominate in wide use. Less common are models with
2K or even
4K displays.
Panel type
The type of matrix installed in the screen of a graphic display or computer (see “Type”).
- IPS. The technology provides high quality color reproduction, good brightness and wide viewing angles. In addition, IPS screens are relatively inexpensive to produce, which is why they are widely used.
- H-IPS. A variation of the original IPS technology, designed to increase viewing angles and contrast while maintaining high-quality color reproduction. Used in professional graphics tablets.
— TFT. The simplest type of liquid crystal matrices used in color displays. Such panels provide relatively low, but generally sufficient image quality, and they are noticeably cheaper than more advanced technologies. The obvious disadvantages of TFT are very limited viewing angles.
Colour depth
The number of shades that the device screen can display. The parameter is indicated in bits, not for the entire display, but for each individual base color. Let us remind you that the image in modern screens is based on three basic colors according to the RGB scheme - red, green and blue. 6-bit depth means that the display is capable of producing 2^6 shades of each base color, i.e. a total of 64 shades of red, green and blue. The total number of shades is 64*64*64 = 262,144 (262 thousand). In screens with
8-bit depth, there are already 256 shades for each basic color - in total, they are capable of displaying over 16.7 million colors. And the most advanced displays support
10-bit color depth, allowing you to work with more than a billion shades.
High color depth is important for professional graphics and related tasks that require high color accuracy.
Colour gamut (NTSC)
The range of colors that can be displayed on a graphics tablet screen. The parameter is indicated as a percentage relative to the coverage of the NTSC color space. The larger the color gamut, the wider the capabilities of the screen and the better the quality of its color rendition, which is extremely important when working with graphic materials.
NTSC is one of the first color models, launched in 1953 for color television. And it is still used to describe and compare matrices. The NTSC model covers a larger range of colors than the standard sRGB used in computer technology, so even a relatively small number of percentages corresponds to a fairly wide coverage. For example, a value of 72% or more according to NTSC is considered a decent indicator for use in design and graphics.
