The right display for my application
A decision-making aid for anyone faced with the task of selecting the right display for a new device or an update. The choice is huge, from STN text displays and graphic displays to high-resolution colour displays with touch. There are good arguments for all display technologies (see below), because the "ideal display" that fulfils all properties optimally and is also inexpensive to purchase has not yet been invented. Monochrome displays, for example, are not as stylish as colour displays, but they do save energy and are generally very easy to read in sunlight. And although OLED displays have been under constant development for many years, they are rarely a complete replacement for LC displays. A good way to narrow down the almost unmanageable variety is to approach it from the point of view of the application or the requirements.
Handheld / energy-saving
The device is compact and probably even battery-operated. The integrated display must be correspondingly small and possibly flat. The width should not exceed 80 mm. A 3.5 inch display, for example, is a convenient size and can also be installed upright ("portrait" mode).
Inexpensive colour displays are available in this size, as well as high-quality, bright displays using IPS technology. However, power consumption is often also a decisive factor, as it determines the required capacity of the battery...
