Viewing angle around 160°-170° and an excellent contrast say in favor of character displays with OLED technology.
OLED technology (Organic LED) slowly but surely finds its place even in industrial devices. After a big success at mobile phones, where they convince by high contrast and an excellent viewing angle, this technology becomes price-affordable and technologically advanced even for industrial applications.Benefits in short:
- OLED means, that every pixel is principally one „planar“ LED, thus each pixel emits light (white, RGB or some color). That means, that OLED doesn´t have / doesn´t need backlight and it also helps to a high contrast, as there´s no problem with a light bleeding through “off” (black) pixels, as it is often at LCD displays. High contrast also ensures excellent legibility even at a strong daylight.
- wide viewing angle. As every pixel (point) is itself a light source, it shines in all directions (half-globe) and it provides an extreme viewing angle near to a theoretical maximum of 180°
- extremely wide operating temperatures range, frost doesn´t “slow down” display response time
- the same color from every viewing angle. This is vital at color (RGB) OLED displays and it means almost zero color shift at viewing from various viewing angles, so well-known from TFT LCD displays
- low power consumption, partially dependent on a display content (number of switched-on pixels and their intensity)
New character displays from company Winstar belong to advanced displays with declared features. In our stock can be found types for example WEH001602ABPP5N00000 (16×2, blue), WEH001602AWPP5N00000 (16×2, white), WEH002002ALPP5N00001 (20×2, yellow/orange – „amber“) and WEH002004ALPP5N00000 (20×4, yellow/orange – „amber“) and other. They all have 8-bit parallel interface „6800“ and a modern controller WS0010. Direct comparison of OLED display with an FSTN LCD is best illustrated in the attached video.

After unveiling the world’s first flexible OLED TV at CES earlier this year, LG has gone a step further with the unveiling of two new 18-inch OLED panels: the first is a transparent display, while the second can be rolled up. Although both fall short of the 77-inch flexible TV on show at CES, the company says the new panels prove that it has the technology to bring rollable TVs with screens in excess of 50 inches to market in the future.

So it’s been a while since I last posted about my OLED watch, and I’ve done a lot of work on it! (And also broke it multiple times)
It’s taken me a lot of work to get this far, and I developed EVERYTHING from the ground up. The electronics design, the PCB layout, the RTOS and firmware drivers, the graphics engine, the user-mode app code, and even USB communications apps. I’ve used C, C#, and Python extensively in this project, and Altium Designer for the schematic and PCB.
Overall it has been an awesome learning experience, and if I was to make another one I would do a lot of things differently!

The WifiDuino is the chip-sized Arduino + Wi-Fi + 128×64 OLED at low price that is easy to use.
WifiDuino is an open-source Arduino-compatible, wifi-enabled board. It allows users to use Arduino IDE (Integrated Development Environment) interface to write programs directly, and with Wi-Fi function. WifiDuino is user friendly, get started in no time. What’s different from Arduino Wi-Fi shield is that WifiDuino is a lot smaller in size, cheaper and easier to use.
WifiDuino is an open source project, which means you are welcome to develop and improve the project if you want. It is also ideal for beginners too. WifiDuino and Arduino are used the same chip. You can quickly learn how to make things with WifiDuino with its rich library resources from the Arduino database.

OLED Watch v4.2 @ Walltech. John writes-
I just finished writing up my OLED Watch project on my website! I took loads of great pictures, and explained the whole thought process of the project, as well as the hard ware and software behind it! I’ve officially released the board files and the code under the appropriate creative commons licenses, and just wanted to let you know that it’s all now online on walltech.cc! You guys have been strong supporters of my projects and really thank you for that.

Organic LED, microprocessor controlled, intelligent energy source for all of your electronic devices.
Legion is a portable energy source with a built-in Organic LED display coupled with a microprocessor. It can charge any USB powered electronic devices. Unlike a traditional portable battery where you’re left in the dark about the state of charge of your battery, Legion learns how you use your electronic devices and displays precisely how much more time (day:hours:minutes) you have remaining until you run out of power. Legion uses premium grade Lithium Polymer batteries designed to maximize your energy density while packing it into the smallest area possible. Legion is proudly designed in Silicon Valley, California.

(Phys.org) —A device created by UCLA researchers could lead to a significant leap in the quality of images on smartphones, computer displays, TVs and inkjet printers.
The new material, and a new manufacturing process developed at UCLA, are used to produce semiconductors that are essential to liquid crystal displays and organic light-emitting diode, or OLED, displays.
Led by Yang Yang, the Carol and Lawrence E. Tannas Jr. Professor of Engineering at the UCLA Henry Samueli School of Engineering and Applied Science, the team created a high-performance device that can be produced without requiring a clean room or the expensive equipment now commonly in use.

by Kalle Hyvönen:
I needed a display for a project of mine and was just going to use a regular HD44780 -based text LCD display, until I spotted some very neat looking TINY OLED-displays from eBay.
The displays are monochrome 128×32 pixel displays with a 4-wire SPI bus and they are around 30x11mm in size (the actual display area is under an inch diagonally!). The exact type of the displays is UG-2832HSWEG04. I found a datasheet for the displays and a datasheet for the actual display controller (SSD1306) and they seemed easy enough to use so I ordered a two of them for just $13.

Here’s Oscar Liang another Arduino GPS project, he writes:
Garlow stands for GPS Arduino Rechargeable Logger OLED Watch. The device gives GPS information which is logged on SD card and shown on a OLED display. It can be carried as a watch or simply used as a GPS data logger. The whole system is based on Arduino Nano, with a Lipo power management module which enables USB battery recharge.
