# Brightness

## Overview

Drawing tablets with embedded display panels have a maximum typical brightness. You have been exposed to many display panels in televisions, phones, and watches. Here I'd like to set your expectations for brightness on drawing tablets.

## Measurement

Brightness is measured in cd/m2 ([candela per square meter](https://en.wikipedia.org/wiki/Candela_per_square_metre)), but that is hard to type, so many people use the equivalent unit of **nit**.

## Lighting conditions

The environment you use the tablet in greatly affects the brightness you need. Below is my take on what you need under different conditions.

| Environment                | Notes                                                                                                                                                                                                              |
| -------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **indoors + dark**         | <p>Low amounts of ambient light. Light conditions are not changing.</p><ul><li>200 to 250 nits is enough</li></ul>                                                                                                 |
| **indoors + bright**       | <p>Lots of ambient light. Maybe due to bright indoor lights. Maybe due to windows. If there is a window, brightness may change dramatically because of cloud cover.</p><ul><li>250 to 350 nits is enough</li></ul> |
| **outdoors + under shade** | <p>Overall bright environment with lots of ambient light. No direct sunlight hits your tablet.</p><ul><li>>=500 nits are needed</li></ul>                                                                          |
| **outdoors + no shade**    | <p>Very bright. Sunlight hits your tablet.</p><ul><li>>=1000 nits are needed</li></ul>                                                                                                                             |

## What you can expect from drawing tablets

Overall, display panels for drawing tablets fall in the range of 200 to 400 nits.

* Many are within the range 220 to 250 nits.
* Only a few are >= 300 nits.

## Fan noise

A few tablets - only Wacom as far as I know - have fans. These fans help keep their brighter displays cool. The fan noise can be disturbing for some people. For others, it does not matter.
