In a wide portfolio of development tools for displays from company Electronic Assembly can be found evaluation boards for development of applications with eDIP displays family, including a connectivity via all common industrial interfaces.

Everyone who already ever designed his own development board knows, that it takes a lot of time to design, construct and assemble such a board. That´s why a ready-made development board at an affordable price is always a big simplification. EA EVALeDIP320-TFT70 development kit is a beautiful example of such a set, as it provides an immediate access to a full display functionality and it comes rich-equipped. At the same time it meets a criterion of an acceptable price, because the difference in price of the development board and the display itself is approx. 50 Eur only.

EA EVALeDIP320-TFT70 enables to develop applications in an elegant way and to use all possibilities of 5.7“ and 7“ Electronic Assembly displays. The development kit contains an evaluation board (USB), 7″ display with a touch panel, CD with SW and drivers, 5 small PCBs enabling a communication through industrial interfaces (RS232, RS485, I2C, SPI and RS232-CMOS level), USB cable and a line adapter. The development kit enables to also develop applications, which use input/output pins of the display – 8 push-buttons and 2 trimmers enable to control I/O pins and simulate analog signals, while 8 LEDs indicate logic levels at the corresponding outputs. Another LEDs indicate data traffic and a beeper/ loudspeaker serves as a touch feedback. An advantage of Electronic Assembly displays is, that black-anodized aluminium frames (bezels) are available for many types.

Further information will provide you the EA EVALeDIP320-TFT70 and EA eDIPTFT70-A datasheets. A 5.7” display will be available in the nearest period. In case of interest in Electronic Assembly products, please contact us at info@soselectronic.com

I like fast things. And good code. Often, they go hand in hand. This is a demo of my optimized library, LiquidTWI, pushing data out to the LCD almost as fast as the “native” (direct) interface with LiquidCrystal. Only this time, using just 2 wires (TWI).

New intelligent display eDIPTFT70 from Electronic Assembly provides all what its smaller relatives and something in addition – the size.

With the 7” size and an 800 x 480 pixels resolution, it can display a relatively considerable amount of information. Similarly like other member of family eDIP (eDIPTFT32 a eDIPTFT43), even eDIPTFT70 eliminates the need of demanding and time-consuming programming at pixels level.

All the control of the display is done on commands level, thus to display text, graphics and many other symbols is exceptionally easy and simple. Control by commands substantially accelerates development and shortens the time to market. At an application development it is possible to use predefined functions, symbols and geometric functions, bargraphs, frames, buttons and many other. In general eDIPTFT70 offers almost the same functions like other eDIPTFT family members, including almost immediate start within a few 1/10 of second.

Single +5V supply, analogue touch panel with a variable raster and software-dimmable backlight brightness contribute to the versatility of usage. In many of applications also 80 various short jingles for audio feedback can be useful. Even eDIPTFT70 contains 3 communication interfaces – RS232, I2C and SPI, that´s why it can be connected to virtually any device. Further information will provide you the eDIPTFT70 datasheet.

The TWIDisplay 8-digit LCD is an easy to use 8-digit 14-segment transflective LCD display. Libraries for Arduino and avr-gcc are available on GitHub.

Only four wires are required for operation, one for power (runs on both 3.3V and 5V), one for ground, and two for the TWI protocol. To control a display like this, a dedicated controller chip is required.

We came across Scott Harden’s brief article describing how to control an HD44780 LCD using an Attiny2313. After a number of unsuccessful attempts with other code he found this LCD library written by Martin Thomas for use with AVR-GCC. With a few mods to the code Scott produced the above results controlling his 2×20 LCD in 4-bit mode. The code provides for scrolling and wrapping and can even display Japanese characters. A handy tip for ATTiny2313 users.

LG Display has announced a 5-inch, full HD LCD panel for smartphones – the highest resolution mobile panel to date, giving a clear indication that the 720p display on your current top-end smartphone won’t reign supreme for long. This new, 5-inch Full HD LCD panel is a step forward from the existing mobile display technology and is based on AH-IPS (Advanced High Performance In-Plane Switching) technology. It features a 440ppi and 1920×1080 resolution, providing, for the first time, Full HDTV quality on a smartphone. We had first carried a story about AH-IPS displays, way back in May 2011 and LG had announced then that they were indeed developing AH-IPS panels for smartphones. Here’s how AH-IPS improves on the existing technology.

I was digging around trying to find some information on an obscure LCD module, and came across this interesting table (compiled partially in Russian) that correlates a lot of older mobile phones with their specific LCDs, LCD controllers, dimensions, serial bus, etc.  If you’re looking for cheap LCDs of a specific physical size or resolution, this might be a good starting point since there may still be spare parts floating around out there.  If nothing else, it’s just an interesting read looking at how much time and effort went into this thing (presumably a repair shop owner, or something similar).  Original Excel Spreadsheet: http://vrtp.ru/index.php?act=Attach&type=post&id=385043, or safer HTML conversion courtesy google.

uLCD-14 replaces the previous model uLCD-144. The new type remains a full software compatibility, that’s why if you already have an application designed for uLCD-144, you can use them without any modification.

The only main change is the connector, instead of the original 1×9 THT pin header a new 2×5 SMD pin header is used with an added +5V output through a protection schottky diode. The new uLCD-14 module, also marked as uLCD-144-G2, features the same excellent properties like other members of uLCD family.

Properties of the module are mainly determined by the used Goldelox chip, able to work in a slave, as well as stand-alone mode. It is also possible to use the 4D-Visi graphic development environment, considerably simplifying and accelerating a development of graphic applications. A detailed description of features common to all 4D Systems modules you can find in our article. Detailed information will provide you the uLCD-144-G2 datasheet.
