BACKLIGHT DEVICE AND DISPLAY Russian patent published in 2016 - IPC G02F1/1335 

FIELD: construction.

SUBSTANCE: backlight device comprises support element, in which light-guiding plate, and light source circuits are installed. Support element has space for arrangement of printed circuit board in the area located along longitudinal direction of end surface of light-guiding plate and passing from the side of end surface of light-guiding plate to back surface of light-guiding plate. Light source includes bending printed circuit board, containing first and second sections, and bending line is a dividing border between them. First section comprises multiple light-emitting chips arranged in rows, and second one includes tightly packed part of light-emitting microchips interconnection structure. Light-emitting microchips are divided into two or more units for partial excitation of light-emitting microchips. In each unit microchips are connected in series. Parts of interconnections allocated from each unit are oriented along printed circuit board width in direction of mentioned second section of bending printed circuit board.

EFFECT: at second section of bending printed circuit board mentioned parts of interconnections are oriented in longitudinal direction of printed circuit board parallel to each other.
