LEDs, 18 pieces placed along the long side of the display, which makes the whole screen illuminated evenly. Of course, small areas with uneven lighting could not be avoided, but given the screen size, the work was worthy.

For reading texts, consisting of two columns, often found in various articles and magazines, you can use the auto split page into two equal parts, between which movement is to be carried out with the buttons of paging.

You can manually select the number of parts into which is divided the page (from two to nine) and the path that will move the picture when you press the buttons of paging. It allows you to read almost any graphic works (including in cbr format), without having to use the touch screen in an endless attempt to adjust the picture position.
