Electronic device comprising flexible circuit board

An electronic device (101) comprising:

• a first circuit board (310);
• a second circuit board (320) electrically connected to the first circuit board (310);
• a first flexible circuit board (331;
• 531;
• 631) electrically connecting the first circuit board (310) and the second circuit board (320);
• wherein at least a portion of the first flexible circuit board (331;
• 531;
• 631) is deformable according to a movement of the first circuit board (310), wherein the first flexible circuit board (331;
• 531;
• 631) includes a first flexible portion (3313;
• 5313;
• 6313) and a first rigid portion (3311;
• 5311;
• 6311) formed between the first circuit board (310) and the first flexible portion (3313;
• 5313;
• 6313);
• and
• a second flexible circuit board (332;
• 532;
• 632) electrically connecting the first circuit board (310) and the second circuit board (320),
• wherein at least a portion of the second flexible circuit board (332;
• 532;
• 632) is coupled to the first flexible circuit board (331;
• 531;
• 631) and is configured to be deformed by a deformation of the first flexible circuit board (331),
• wherein the second flexible circuit board (332;
• 532;
• 632) includes a second flexible portion (3323;
• 5323;
• 6323) and a second rigid portion (3321;
• 5321;
• 6321) formed between the first circuit board (310) and the second flexible portion (3323;
• 5323;
• 6323), and
• wherein a first boundary portion (5381;
• 6381) formed between the first flexible portion (3313;
• 5313;
• 6313) and the first rigid portion (3311;
• 5311;
• 6311) is dislocated from a second boundary portion (5382;
• 6382) formed between the second flexible portion (3323;
• 5323;
• 6323) and the second rigid portion (3321;
• 5321;
• 6321).
