How Does a Drawing Tablet Work? A Complete Guide

How Does a Drawing Tablet Work? For those wondering whether to use a graphic or drawing tablet, it is important to note that the two of them work the same way.

Both a drawing tablet and a graphic tablet will connect to another device such as a laptop or Android phone as a platform to host the drawing software.

You will then draw on the tablet-sensitive surface while looking at the laptop or phone screen for the drawing tablet. You will draw on your tablet surface with a stylus pen as you look at your laptop screen.

For the drawing tablet, the display on the laptop screen will be projected to the built-in tablet screen such that you will be able to view the software display on your tablet.

Tune in as we dive into this mysterious world and explore the science behind graphics tablet technology. At its most basic level, a graphics tablet uses an electromagnetic grid and an electronic stylus to measure pen pressure and button clicks. 

The stylus has a coil of wire that generates electrical energy when exposed to the grid’s electromagnetic waves. The tablet analyzes this electrical energy and uses it as input for controlling the cursor. Let’s break down exactly how graphic tablets work their wonders in detail.

What Is a Drawing Tablet?

What Is a Drawing Tablet

A drawing tablet is a device that has a flat sensitive surface or screen that interacts with a sensitive pencil to draw on it. It is also referred to as a Graphic Tablet. When a drawing tablet is paired with a stylus and connected to a drawing software, it allows you to draw on the sensitive surface either looking at your computer screen, or on the tablet screen depending on the type of tablet you use.

The simplicity of using a tablet just like pen and paper to draw makes it possible for rookies and beginners to easily start off a drawing career with ease. Drawing tablets can be used for diverse functions including graphic design and image editing.

  1. Connect your tablet to your computer or laptop using your cable or wirelessly. Visit the brand page of your tablet manufacturer to download relevant drivers. For example, check out our guide for Downloading GAOMON Drivers.
  2. Some tablets have problems connecting with different systems such as Android OS or Windows. Make sure to choose a drawing tablet compatible with your computer.
  3. Open your drawing software such as Adobe Illustrator on your computer. Simply start drawing.

Components of the Graphics Tablet – No screen

A graphics tablet consists of two important components, which are a tablet and an accompanying stylus. The styluses used on graphics tablets come in a variety of types. Among them, there are battery-powered styluses, rechargeable styluses, and EMR (electromagnetic resonance) styluses. 

Battery-powered styluses are powered by an internal battery and require regular replacement, depending on usage. Rechargeable styluses have an internal battery that can be recharged via micro USB or another power source. 

EMR styluses use electromagnetic induction to detect contact with the tablet surface, giving users greater precision when drawing and creating digital artwork. 

Out of the three types available, the EMR type is generally the most popular due to its superior performance and accuracy compared to other types of stylus. It also offers greater durability since there is no need for a battery replacement or charging process.

A grid of parallel wires on the tablet responds to the stylus hovering above it, so users can control their cursor precisely.

The stylus has coils of wire inside it. These allow signals to go between the stylus and the tablet. This lets the left mouse button work when you touch the tablet with the stylus.

Most modern-day graphic tablets contain an internal battery that allows them to remain powered on even without being connected to another device. 

Working Methods of Both Graphics Tablet and Stylus

The working methods of both a graphics tablet and stylus are based on the same technology known as electromagnetic resonance (EMR). 

This technology allows the battery-free stylus of the pen tablets to receive power from the tablet itself wirelessly. The grid of parallel wires in the tablet transmits electromagnetic waves, which are then picked up by a coil of wire in the stylus. 

This coil then converts these electromagnetic waves into electrical energy, which is used to measure and detect pressure levels and button clicks. 

Data is then sent back to the tablet via electromagnetic waves generated by the stylus coils. The tablet scans for incoming signals and calculates their location, thereby tracking the position of the pen accurately. 

In addition to this technology, recent developments have enabled further refinement in accuracy levels through enhanced detection capabilities such as tilt sensing and hovering recognition. 

Tilt sensing utilizes multiple sensors placed at different angles within a pen tip or eraser, which can detect up to two axes of movement, allowing for more intricate digital designs with improved precision. 

Hovering recognition also works similarly to tilt sensing but uses additional sensors to detect how far away from the surface you are holding your pen, thus providing greater control over digital art. 

Types of Drawing Tablets

There are three different types of graphics tablets available. The first is a simple graphics tablet, which does not have a built-in display or monitor. 

This type of tablet requires that users look at the computer monitor while drawing on the tablet with a pen or stylus. With such a setup, it takes some time for users to get used to hand-eye coordination to draw accurately and effectively. 

The second type of graphics tablet is a graphics display tablet with a built-in screen or monitor. Drawing on this type of device is much more intuitive as you can directly see what you are creating with your pen or stylus and adjust accordingly as needed. 

It also eliminates the need for hand-eye coordination, as all your strokes and edits will be reflected directly onto the monitor’s surface. 

The last type of graphics tablet is a standalone or pen computer tablet, it requires no connection or pairing with a computer to use. This type of device allows users to draw without being bothered by wires and cords linking them to any other devices.  Check out

While such tablets may not be suitable for professional use due to their limited features, they can be quite useful for casual hobbyists looking for something basic yet reliable enough for their artwork.

Can You Use Any Pen on a Drawing Tablet? 

When using a drawing tablet, it is important to check which types of digital pens are compatible with it first. Since not all styluses may be supported by different graphics devices and software. 

Accordingly, many modern tablets feature universal compatibility with most digital pens and even come preloaded with useful drawing software so users can easily get started sketching or painting right away.

Graphics tablets have revolutionized the art world, providing previously impossible levels of accuracy and precision in digital artwork. 

Through electromagnetic resonance (EMR), these tools can communicate wirelessly with their styluses to provide a level of detail that rivals traditional media, with no batteries or cables required. 

For those who use them often, understanding how they operate is key for leveraging all the capabilities at your fingertips so you can create truly breathtaking pieces.

  1. What’s the Size of a Graphic Tablet?

    The graphic tablet size can vary, with common sizes ranging from 6 by 4 inches to 13 by 9 inches. Some even come in 8-by-5 inches or 10-by-6 inches. 

  2. Do drawing tablets have to be connected to a computer?

    Many Graphic Tablets have a screen but no computer. However, in recent years, it is possible to have versatile drawing tablets that have both a computer and a screen. These ones do not have to be connected to a computer to use. A good example is Simbans PicassoTab X14.

  3. How does a drawing tablet detect a styluspen?

    Drawing tablets incorporate magnetostriction technology, employing wires crafted from a unique alloy and stretched across a solid substrate. This technology ensures precise positioning of the stylus tip or the center of a digitizer cursor on the tablet’s surface.
