YNVISIBLE SEGMENT DISPLAY

The Ynvisible Display is a so-called Electrochromic Display (“ECD”) based on organic electrochromic polymers. It is categorized as a reflective display – meaning that it reflects ambient light instead of using a backlight. The displays are screen-printed on a plastic substrate, which makes the displays very thin and flexible.

Eco-friendly and non-toxic display alternative thanks to energy-efficient production processes, organic materials, and overall low material usage. Ynvisible’s displays are a choice for single-use and disposable products.

WHERE TO START?

Starting with the Clicker to get a feeling for how the displays behave when a positive, negative, or no voltage is applied. You can also activate the display and disconnect it from the Clicker to observe the image memory effect.

1. CLICKER

No matter your level of expertise you will be able to use this device.

Ynvisible Display Kit - Clicker

Step 1: Remove the insulating strip from the battery

Note: please remove the battery if you are not using the device for a long time.

Step 2: Insert the display in the ZIF Connector

  1. Open the locking bar (use your fingernail to open it 90 degrees)
  2. Insert the display connector tail into the ZIF connector.
  3. Close the locking bar

Step 3: Drive the display

  1. Press the button on the right to turn the display on (hold for ≈1 second)
  2. Press the button on the left to turn the display off (hold for ≈1 second)

2. DRIVER

The display driver is a simple and intuitive tool to operate the display. By connecting it to a development board such as an Arduino you can implement it directly into your prototype. With our software library, you will be up and running in no time.

Ynvisible Display Kit - Driver

REQUIRED HARDWARE

  1. Ynvisible 2×7-segment display (or another design if you prefer)
  2. Ynvisible Display Driver
  3. Arduino Uno (or other Arduino with I2C interface)
  4. Four jumper wires (male-female)

REQUIRED SOFTWARE

  • Arduino IDE (we will provide you)
  • Arduino Library for the driver 4.1, RDOT_ECD_I2C_1.0 (we will provide you)

‍CONNECTING THE COMPONENTS

  1. Connect the Arduino to the driver board with the jumper wires.
  2. SDA to A4 (On Uno) or SDA pin
  3. SCL to A5 (On Uno) or SCL pin
  4. VCC to 5V
  5. GND to GND
  6. Insert the display in the connector on the driver board. Make sure that the display electrodes are well aligned with the connector electrodes. The leftmost display electrode must be connected to the leftmost electrode in the connector.

How to use the driver in Ynvisible Display Kit

ADD THE LIBRARY TO THE ARDUINO IDE

  1. Install and open Arduino IDE
  2. Click “Sketch”/”Include Library”/”Add .ZIP Library…” in the main menu
  3. Go to your downloads folder and choose RDOT_ECD_I2C_1.0.zip

UPLOAD YOUR FIRST CODE

  1. Connect the Arduino to your computer with a USB cable
  2. Create a new file in the Arduino IDE
  3. Replace the code in the editor with the code below:
#include <RDOT_ECD_I2C_1.0.h>

int i2c_address = 43;         //The i2c address of driver board 4.1
int number_of_segments = 15;  //Number of segments on display (1-15)

RDOT_ECD ECD(i2c_address, number_of_segments); //ECD Object

void setup() {
}

void loop() {
  for(int i=-99; i<100; i++){ //Counting from -99 to 99.
    ECD.setNumber2x7(i);      //Set display to number i
    delay(5000);              //5 seconds delay between each update
  }
}
  1. Click “upload” (the right arrow on the upper left in the Arduino IDE)
  2. Congratulations! Your display should now count from -99 to 99.

3. ADAPTER

The adapter enables you to delve deeper into the possibilities of driving the display and connect it to your existing system with little or no additional components. Our display can be connected directly to most microcontrollers.

Ynvisible Adapter

CONNECT THE DISPLAY TO THE ADAPTER

  1. Insert the display in the ZIF connector, ensuring that the electrodes are aligned. The leftmost display electrode should be aligned with the leftmost pin on the ZIF.
  2. If the displays do not fit a connector, simply use a pair of scissors to cut the electrodes and/or excessive plastic into a suitable size and shape.

Use Cases

LOGISTICS MONITORING
Cost-effective, energy-efficient, lightweight and thin displays are bringing value in cold chain monitoring, impact detection, and various sensor threshold labels. The Ynvisible’s display is an intuitive interface for visually communicating if something has gone wrong throughout the supply chain.

SMART CARDS & LABELS
The market for various smart cards and labels is booming. The ultra-thin and bendable display can be used for a variety of applications, such as dynamic CVV/CVC codes and other sensor readouts.

CONSUMER ELECTRONICS
Electronics are no longer only flat and wired. A flexible and ultra-low power display with multiple color options opens up new form factors and design opportunities. Instead of using the old-fashioned segmented LCD displays, Ynvisible offers a more energy-efficient and optically appealing alternative.

MEDICAL TECHNOLOGY
The environmental friendliness, readability, and bendability features make the printed electrochromic display well suited for medical products, including inhalers, fever thermometers, disposable medical technology devices, and smart tags.
