# Brightness

## Overview

Drawing tablets that have an embedded display panel and those display panels have maximum typical brightness. You have been exposed to many display panels in televisions in phones and watches. Here I'd like to set your expectations about what you're going to experience in terms of brightness for 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 man people use the equivalent unit of **nit**.

## Lighting conditions

The environment you are using 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 be to bright indoor lights. Maybe due to windows. If window, then 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 hitting your tablet.</p><ul><li>>=500 nits is needed</li></ul>                                                                 |
| **outdoors + no shade**    | <p>Very bright. Sunlight hitting your tablet.</p><ul><li>>= 1000 nits is 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. And these fans help to keep their brighter displays cool. The fan noise can be disturbing for some people. For others it doesn't matter.
