New graphic display EA DIP180B-5NL brings a high contrast, small power consumption and a fast response. And what is important for the most of people – it is also available with a touch panel.
Display EA DIP180B-5NLWTP was designed for use in industrial control panels. That´s why it is available with an analogue resistive touch panel. This enables to combine control of a device and display of information into a single unit. EA DIP180B-5NLWTP is a graphic display with 180×32 pixels resolution. It contains 3 integrated graphic controllers SED1520 type (or compatible) used to control left, center and right sections of the display. White LED backlight provides crystal-clear picture and excellent readability under all light conditions.
Touch panel is linked to an external controller or a controller with analogue inputs. Touch panel operates similarly like a potentiometer – if a voltage is connected to the „Top-Bottom“ input of the controller, a voltage proportionate to Y (vertical) position is read by a microcontroller from the „Left-Right“ input. By the same process can be a horizontal – X position of a contact determined. Display provides a high level of contrast and a fast response thanks to the use of an LCD „supertwist“ technology. Even at extremely low temperatures of -20°C, the response time is a sufficient 2.5 sec. Module features an automatic temperature compensation, that´s why they don´t require any external contrast compensation during operation. Together with a wide specified temperature range from -20 to +70 °C, the display is ideal for various industrial applications. To fix the module mechanically, it is necessary only to solder pins directly to a PCB, without a need to use screws or other mechanical components.

Programming of a graphic interface perhaps cannot be any simpler. Company 4D Systems brings to developers a new powerful graphic editor, which further shifts borders of simplicity and speed at a creation of a graphic output.
4D ViSi tool enables to very easily and intuitively arrange graphic control and displaying elements into the layout which we wish to achieve on the 4D Systems display modules. As a result, this way you will create the graphic interface very quickly and you can fully focus on the main – the application itself. In other words – you can put your effort to what the application “has to do” and not “how it should look”.
4D ViSi tool is a part of the 4D Workshop3 IDE – Alpha program, which is free to download. 4D ViSi is a powerful SW tool, which enables an immediate overview of your desired graphic layout for 4D Systems display modules. 4D ViSi contains a set of various dials, gauges and meters, which can be simply dragged and dropped onto the desired place. Every item has wide possibilities of adjustment. Without necessity to always reload the source code to a display module, you have a possibility to see every change on a monitor of your computer and all relevant code is inserted into the program at one click. In the enclosed video you can gain a closer view of the work in this program.
Focus on application itself and the 4D ViSi will take care about its look – [Link]
These displays are small, only about 1″ diagonal, but very readable due to the high contrast of an OLED display. This display is made of 128×32 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!

This is a quick tutorial on getting a VFD working with an Arduino (or Arduino equivalent system). VFDs are beautiful devices with a wonderful hexagonal mesh of wires and this lovely green/blue glow. Operating at around 5V, they offer a nice alternative to high voltage Nixie tubes, while still retaining a lot of the charm.
This tutorial will show you how to connect a Arduino-like device to a VFD display as well as a basic program to display text.

DOG series will start with 3 types: 1×8 character, 2×16 and 3×16 character. Outline dimensions are very compact with 55x27mm and especially designed for handheld applications and low power applications. Thanks to the most modern Chip-On-Glas technology (STN and FSTN) overall height is 2.0mm only. Even together with LED backlight thickness will increase to 5.8mm only. Operating temperature range of –20..+70°C (temperature compensated) is standard.
Standard character height of 5.57 mm for the 2×16 makes „DOG modules“ easy readable. User can decide for 3 different interface 4-Bit, 8-Bit and SPI. No need to say that character set with full 248 ASCII characters is installed. Because of direct placement onto pcb production and mounting cost are unequaled low. No special mounting is required.
Combining various display technologies (positive/negative, blue/green/black) with different backlights (white, blue, amber, yellow/green, red) gives the advantage of many different design looks.

New graphic displays EA DIP122-5 series with efficient LED backlight are optimized for good legibility even in demanding light conditions like for example at the direct sunlight.
Graphic displays EA DIP1222-5 with a 122×32 pixels resolution feature an excellent contrast and an efficient LED backlight offers great legibility even in a low ambient light environment. They are equipped with a temperature compensation for an increased working temperatures range from -20 to +70°C, without necessity of contrast adjustment. Displays also feature a „superfast liquid technology“, ensuring a sufficiently quick response time even at extremely low temperatures (average 2 sec at -20°C).
Three colour versions are available: yellow/green, amber and blue-white. Yellow-green and amber variant is particularly suitable for outdoor usage and extreme light conditions, while an effective LED backlight enables their usage even in a low ambient light environment. Blue-white veriant is optimized with respect to contrast and is ideally suitable for indoor usage with or without artificial light and when low energy consumption is vital.
Displays contain 2 built-in controllers (PT6250 compatible), while every controller is assigned to 61 columns. For external communication an 8-bit interface is used. An external series resistor or constant current source is all that is needed for the LED background illumination. The displays are easily soldered to the printed circuit board or socket connectors can be used if desired. New graphic displays offer for a customer also a high flexibility in a possibility to use a graphic or a character display module for various versions of a given device. As a character display modules types EA DIP081-CHNLED (1×8), EA DIP162-DHNLED (2×16) a EA DIP204-4HNLED (4×20) with the same casing and pinout can be used. .

HD44780 based LCD displays are very popular for embedded projects because they are cheap, easy to interface, can display characters, consume power lot less than seven-segment displays, and most of the present day compilers have in-built library routines for them. However, the only disadvantage is that they require at least 6 I/O pins of microcontroller. Well, you may ask, isn’t that less than what seven-segment displays require? Yes, that’s true but there are circumstances where you don’t have left enough pins for LCD display.

Pretty much ever since the iPhone 4 with retina display was launched, resolutions have played a major role in smartphone market. In September, Samsung unveiled Galaxy S II HD LTE, which sports a 4.65″ 1280×720 display. That was the first smartphone with HD resolution (720p). Now there are already a few phones with HD resolution, for example Samsung Galaxy Nexus and LG Optimus LTE. Higher resolutions are not only courtesy of smartphones as “retina” displays are coming to tablets as well. On May, Samsung showed off a 10.1″ panel with resolution of 2560×1600 – resolution that’s only seen in high-end 30″ monitors.

The MAX7219 does all the control and refresh work for you in driving either an 8×8 matrix display or 8 x 7-segment displays (usually these also have a dot so its really an 8-segment display) – 64 LEDs total. All you have to do is send it serial commands via the 4-pin SPI interface and it will auto-magically take care of the rest. Wiring is simplified as well, you only need to set the current level for all LEDs with a single resistor instead of 8 and you can also dim the entire display digitally. It’s a thru-hole chip so you can use it in any breadboard, perfboard or other project, although if you’re soldering it in, we suggest using a socket.

I found these electromechanical vane displays on eBay and accidentally won them. So, here they are! These are seven segment displays. Each segment is painted a bright yellow and fluoresces under UV light. The segments do not actually draw any power except when they are moved. Behind each segment is a solenoid that flips the segment on or off. Several units are then daisy chained together to form larger numbers. Watch the video below to see it in action and be sure to check out the image gallery.
