Display
screen size
7.8"
The size of the screen (measured diagonally).
is self-lit
✔PocketBook InkPad 4
Self-lit devices have a back or front light incorporated, so they can be used in poor light conditions or in the dark.
pixel density
300 ppi
Pixel density is a measurement of a screen's resolution, expressed as the number of pixels per inch (PPI) on the screen. A higher pixel density translates into more clarity and sharpness for the images rendered on the screen, thus improving the quality of the viewing experience.
Has an e-paper display
✔PocketBook InkPad 4
An e-paper display provides a high contrast allowing users to read in direct sunlight without requiring much power.
has a touch screen
✔PocketBook InkPad 4
You can operate the device easily, by pressing the screen with your fingers.
has anti-reflection coating
✔PocketBook InkPad 4
This helps to reduce the reflection from your device.
resolution
1404 x 1872 px
Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.
number of screen shades
Unknown. Help us by suggesting a value.
More screen shades (greys) result in better gradients and usually a better reading experience.
has branded damage-resistant glass

RAM
1GB
Random-access memory (RAM) is a form of memory used to store working data and machine code. Having more RAM is particularly useful for multitasking, allowing you to run more programs at once or have more tabs open in your browser.
CPU speed
2 x 1 GHz
The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.
semiconductor size
Unknown. Help us by suggesting a value.
Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.
