Portable display device

A portable display device, comprising:

• a display unit including a light-emitting surface displaying an image and a non-light-emitting surface opposite to the light-emitting surface, the light-emitting surface including a first light-emitting surface and a second light-emitting surface that are continuously disposed on a first substrate and are on opposite sides of a folding line;
• a control unit external to the display unit and controlling an operation of the display unit;
• a battery supplying power to the display unit and the control unit;
• a first flexible film, electrically connecting the display unit and the control unit;
• a second flexible film electrically connecting the display unit and the battery, the first flexible film and the second flexible film extending from the display unit in a direction parallel with the folding line in an unfolded state;
• and
• a third flexible film electrically connecting the control unit and the battery,
• wherein:
• the control unit has a first surface on which the first flexible film is disposed, and a second surface opposite to the first surface,
• the battery has a third surface on which the second flexible film is disposed, and a fourth surface opposite the third surface,
• the portable display device is embodied in:
• a folding mode in which the first and second flexible films are bent in such a way that the light-emitting surface and the first and third surfaces face each other,
• the control unit and the battery supplying do not overlap the display unit in the unfolded state,
• in the folding mode, the portable display device is in a normal folding mode or a portable folding mode, and
• in the portable folding mode, the display unit is bent at the folding line such that first light-emitting surface and the second light-emitting surface face each other with the control unit therebetween.

• a drive unit external to the display unit and controlling the display unit;
• and
• a flexible film electrically connecting the display unit and the drive unit, the flexible film extending from the display unit in a direction parallel with the folding line in an unfolded state,
• wherein the drive unit includes:
• a first surface on which the flexible film is disposed, and
• a second surface opposite to the first surface,
• wherein the portable display device is folded in one of a first folding mode in which the flexible film is bent in such a way that the non-light-emitting surface and the second surface face each other, and a second folding mode in which the flexible film is bent in such a way that the light-emitting surface and the first surface face each other,
• wherein in the second folding mode, the display unit is bent at the folding line such that first light-emitting surface and the second light-emitting surface face each other with the drive unit therebetween
• wherein in the first folding mode, the first and second light-emitting surfaces are substantially coplanar with one another with the folding line therebetween, and
• wherein the drive unit does not overlap the display unit in the unfolded state.
