Making OLED Displays almost everywhere

Via: https://hackaday.com/2021/09/04/making-oled-displays-in-the-home-lab/

Herstellung von OLED Displays im Heimlabor. Es ist also zumindest prinzipiell auch im Home Lab möglich. Abgesehen von ein paar Grundlagen und Standard Equipment, sollte das doch in einer ruhigen Woche zu machen sein 😉 Jedenfalls ist es interessiert anzusehen, auch ohne eigene Ambitionen bezüglich Herstellung. Es gibt so viele tolle Projekte von engagierten Menschen die es echt einfach machen die Dinge auch selbst zu machen. Wenn nur die Zeit für all die genialen Sachen wäre und der Platz ohne den Woman acceptance factor überzustrapazieren. Nur cool reicht bei meiner Herzallerliebsten nicht mehr aus, selbst mit Wireless connectivity nicht.

How to Drive an Electronic Paper Display (EPD) with EFM32

Samsung Galaxy Gear final product

The picture from venturebeat.com was near by the final product. It seems that these guys been well informed.

Every possible question answered in the t3.com article: http://www.t3.com/news/samsung-galaxy-gear-smart-watch-price-release-date-and-specs

In my opinion the less important fact is the availability in six different strap colours, but maybe this fact is the essential argument for someone to buy one.

It’s not a stand alone device, although the hardware specifications (1.63-inch Super AMOLED display, custom built 800 Mhz processor, 1.9 megapixel camera, 4GB of built-in storage.) would provide enough power to do so.

The Galaxy Gear needs a connection to a Note 3 or Note 10, because that are the only devices that been supported at the moment.

The Android 4.3 update for Samsung mobiles enables the S4 to work with the Galaxy Gear.

The price will be about £200 which will be approximately 236,67 € (05.09.2013) when launched at the end of september.

Make a slim watch with ARM Cortex-M3 EFM32

„Hack-a-Gecko project by Anders and Adam

How to make a very slim watch and keep battery life long? In this Hack-a-Gecko project, they tried to catch two birds with one stone.

The Idea
We thought it would be cool to utilize the extremely low power EFM32 in combination with an extremely low power display to create a wrist watch demo application. And usually, the smaller and thinner something is, the cooler it is. (Admittedly, wrist watches do not necessarily follow this trend… big watches.)

Anyway, we wanted it slim. The starting point was the memory LCD display from Sharp (link). It is truly a Nano ampere display technology. And it is also thin, only 0.75 mm. A watch also needs a battery, cool new technologies exist such as the Thinergy battery, but the voltage of 4.1 V is a bit awkward. We decided to use a standard 3.0V CR1616 cell as it can power the EFM32 and display directly. Thickness of battery + display is 2.35 mm, is it possible to design the electronics as well within this thickness limit…? Challenge accepted!“
