E-paper displays
For a long time, electronic paper technology was underestimated. 40 years have passed since it was invented for commercial use. Today, e-paper displays are very versatile, they are appreciated for their energy efficiency and very good image quality. They reflect light, just like paper, which distinguishes them from conventional flat-screen displays. This makes the emitted image more readable and we can see it better even in more difficult conditions, in sunny weather. Moreover, e-paper displays consume little energy, are energy efficient, which in turn results in low operating costs. The image quality, in turn, is also affected by high contrast. E-paper is a technology that provides image display by means of microscopic containers, which are filled with dark and white capsules. In the offer of Botland store you will find a wide range of displays created on the basis of this technology. They are a very good alternative to conventional displays.

Electronic paper - energy-saving and practical displays
Electronic paper uses plastic substrates for the display. This makes e-ink screens flexible - this significantly increases the scope of their use. They can be used as electronic price tags in stores, information boards at bus stations, electronic billboards, and e-book readers. Currently, most e-ink displays are black and white (with the option of gray display).
Low power consumption thanks to the unique operating principle
Many electronic e-ink displays maintain static text or images on the display without access to a power source. They are sometimes called electrophoretic displays. They create images by rearranging charged pigment particles with an applied electric field. Therefore, power for the e-ink screen is only needed when the displayed image changes. Due to their low energy consumption, this type of displays are often used in battery-powered portable equipment.
Clear and ergonomic image
The electronic paper display perfectly emulates a sheet of paper. Thanks to high contrast and the use of only reflected light, these types of screens are not tiring for the eyes. E-ink displays are available in many formats and sizes. Thanks to the relatively high resolution and dynamic range, these displays can present not only text, but also simplified illustrations, icons and graphics. Additionally, the ergonomics of this type of displays is improved by the possibility of mounting flexible screens on surfaces of any shape - thanks to this, the shape of the screen can be adjusted to the geometry of the device.
E-paper displays - FAQ
E-paper, i.e. e-paper display, is a special type of display that imitates an ordinary sheet of paper in its appearance. Unlike standard displays , e-paper does not emit blue light. The principle of operation of displays imitating ordinary paper is based on light reflection. In practice, this means that it is fully readable from various angles. Other advantages of e-paper displays are low electricity demand and high contrast.
When choosing an e-paper display, you should pay attention to several important factors. The first is the communication interface enabling the display to be connected to external devices. The most popular communication interfaces are GPIO, SPI, SPI + I2C, NFC and USB . Another issue is the screen size. The larger the screen diagonal, the more readable the text and graphics displayed. In turn, the quality of the displayed content is influenced by the screen resolution. The higher it is, the more detailed the content is presented.
