Minimal power consumption, slim design and a big amount of available versions with multi-color backlight – these are some benefits of the EADOG series displays.

EADOG series is familiar to many of you and probably it´s your favorite one from these main reasons:

  • displays are unusually flat (thin)
  • the have a very low power consumption of 100-s uA (without backlight)
  • wide possibilities of backlight, monochrome and also RGB
  • some types are well legible even without backlight
  • simple communication through 4/8 bit or SPI interface and newly even I2C

So far, types with up to 128x64px or 3×16 characters were available. The most recent additions to the EADOG family are bigger types with resolution of 160x104px (EADOGXL160), 240x64px (EADOGM240), 240x128px (EADOGXL240) and 4×20 characters (EADOGM204) and appropriate backlight modules EALED66x40, EALED94x40 and EALED94x67. Also these new types maintain a low profile – only 5.8 or 6.5mm with backlighting. A positivity is that even these new types are based on standard LCD controllers.

A guide at a choice of a suitable combination of display +backlight will provide you the application described in our article – Start with the EA DOG displays for free.

Detailed information will provide you the datasheets at particular types.

I am very new to the multicopters hobby and a super newbie to the FPV (First Person Viewer) flying. I’ve never watch in real time someone flying through the screen but I’ve watched hundreds of videos online! The best-case scenario is to use some goggles (like the Fat Shark) in order to have a better experience. This will make you believe that you are actually inside the cockpit flying the machine. And that’s awesome!

But sometimes, even when everything looks simple this is not translated to cheap as well! A good FPV system, from the camera on the copter to the radio transmission system and the screen on the ground will cost you sometimes more than $200 (without even taking the price of the goggles into the equation). This is huge for my budget especially when the cost will be mirrored to a hobby of mine! So, I am going to try the most efficient solution!

High power of the UDOO “asks” for usage. One of many occasions to make it is to use various available periphery thus gaining a truly universal platform.

Favorite powerful embedded SBC called UDOO (S975-G000-2100-C2) already found many fans. Maybe also because of its compatibility with the Arduino Due platform (hardware and software) and mainly, it´s possible to connect it with various accessories. Thanks to a wide range of interfaces (USB, Ethernet, bluetooth, WiFi, …) is a connection of periphery flawless, what´s also a case of the 5MPx camera (autofocus).

Despite miniature dimensions this camera provides very decent resolution and speed – for example VGA (640×480) @90fps or 1080p @30fps, or QSXGA (2592×1944) @15fps. Also beneficial is recording of a video in a full 70°field of view (FOV).For a practical usage and application development with UDOO also serves the „Starter kit EU” containing an adapter for the third USB, RTC battery holder, HDMI cable with the UDOO logo, USB/ Micro USB Type B cable, SATA power supply cable, power supply adapter and an 8 GB micro SD card.

Perhaps the biggest “attraction” is the spacious 7“ display KIT LCD 7”–Touch 800×480 px RGB with a capacitive touch panel. By connecting of this display with the UDOO microcomputer, we get a ready-made platform usable to control various processes, with a power, which easily suits to majority of applications. Detailed information about the UDOO can be found in our article: Do you want a microcomputer which will „handle everything“?.

While TFTs have been the mainstay of displays for years, OLEDs are becoming more prevalent as their price drops due to the phenomenal increase in quality from TFT to OLED technology. We received this demo board from Newhaven that effectively illustrates side by side the differences between TFT and OLED technology, using a 1.69 inch 160 x 128 OLED display and a 1.8 inch 160 by 128 TFT display.

Liquid Crystal Displays (LCDs) are a common and increasingly pervasive method of displaying information for everything from watches to giant TV screens. Though, like most other displays, LCDs require electrical energy to constantly display an image. Researchers from the Hong Kong University of Science and Technology, however, have produced an ultra-thin LCD screen prototype that is not only capable of displaying images without continuous power, but in 3D as well.

The planterbot is a plant monitoring robot. It uses capacitance for sensing moisture from the plant instead of using the usual soil probe, this means that wires don’t go into the plant. It also detects temperature and light using thermistors and Cds photocells and displays the temperature and light graphically on the front facing LCD.

TinyScreen is a tiny customizable display. Play games, get notifications from your phone and display useful information.

TinyScreen is the new way to visualize your environment. With a beautiful color OLED display, TinyScreen is designed to be used to display information from the TinyDuino platform, which stack together like little electronic Lego’s.

With TinyScreen there are several default apps that will work right out of the box – like a Smart Watch app, a Video player app and a video game app. You can use these default apps with NO PROGRAMMING AT ALL!

 I built a custom OBD II gauge in the clock of my Subaru BRZ (GT86, FRS) and a lot of people wanted me to build them one. Here is how you can build one of your own. My wife is about to give birth to our second son and all the code is open source, so I have nothing to lose by posting this.

LG Display has an excellent article on how they build TFT LCD displays:

Ever wondered how the TV and monitor displays you use every day work? The TFT-LCD manufacturing process consists of a set of processes for producing TFT, color filtering, cell, module and others. LG Display Newsroom gives a detailed, but easy to follow explanation of the entire steps below.

Let’s take a closer look at the production process for a TFT board, the bottom-most layer of an LCD panel. The image above depicts a TFT board, which consists of rows of small rectangular sections that together resembles a chessboard. Each rectangular section is a pixel, and each pixel contains a transistor that controls its function. The TFT process is the process that builds these transistors on top of a glass substrate.
