The display you select for your project is equally important as the project itself. One reason is that it governs how your electronic work is displayed. The Eink display stands out and has been adopted by many people around the world. It is significantly better than LCDs or Thin-Film-Transistors (TFT) screens. Unfortunately, eink display is underappreciated and receives little attention.
The reasons why this display is an excellent choice for you are shown below.
What makes the E-ink display unique?
Seven-segment displays and LCDs previously dominated the market due to their ability to deliver pure animated graphics. On top of these foundations, new technology has been developed. The E-ink display is a cutting-edge type of display that lacks an internal backlight. This is advantageous.
Backlights use up a lot of power, which accelerates the battery life of your electronics. The Elink display is energy-efficient and can reduce operating costs because it lacks a backlight. This makes it an excellent option for displaying static content for a long time, making the display appropriate for uses like reading e-books. Additionally, the use of these backlights at night is ineffective because they are only visible during the day.
How the E-ink display work
The e-ink display, also known as electronic paper, uses the reflection principle. Light is reflected within the display, just like it is in LCDs. However, unlike the LCD, the e-ink display makes use of an external light source.
These external light sources, in turn, assist in displaying content on the screen with minimal energy consumption. Internally, this display type is made up of an electronically structured sheet of ink. This layer is responsible for delivering pixels, which are used to determine how rich the picture element in a display will be. Keep in mind that a higher pixel value indicates a better display that will not strain your eyes.
The external light source is designed to pass through both the ink layer and the reflecting region. The reflected light is then used to display the contents so that users can see the output.
Other Advantages of Using E-ink Display
E-ink displays are thin and flexible, in addition to being power efficient. This display type outperforms its competitors, including the TFT, which uses backlight. The e-ink display has a longer battery life because it does not use a backlight. However, this becomes a disadvantage because it cannot be used at night.
Because of their resemblance to printed papers, these displays put less strain on the eyes. They look better and more comfortable to the eye when used for signage and notices. Also, the cost of producing this type of display is significantly lower than the cost of producing other types of display. They are also as durable and adaptable as OLED displays.
As pointed out, e-ink displays are power-efficient and suitable for some mobile applications such as eBook readers. This display is especially suitable for projects that require less energy but still require reliability. So, if you want to build a project with limited funds that is not to be used in the evening, you should probably go with E-ink displays.
