Abstract: Provided is an insulation sheet for a chip on film. An insulation sheet for a chip on film according to one embodiment of the present invention is provided on the opposite surface of a printed circuit film from the surface on which a display driver IC (DDI) is mounted, and is for preventing heat generated from the display driver IC from being transferred in a direction perpendicular to the opposite surface. Accordingly, the insulation sheet for a chip on film is advantageous for lowering the temperature of the display driver IC while minimizing the transfer of received heat toward a display device housing. Moreover, due to the excellent flexibility of the insulation sheet, peeling can be prevented even when the insulation sheet is attached to a printed circuit film that is curved.

Abstract: An insulation sheet for a display light source is provided. An insulation sheet for a display light source according to an embodiment of the present invention is provided on an opposite surface opposite to a circuit board mounting surface on which multiple LED elements configuring a light source of a display are mounted while being spaced a predetermined interval apart from each other, so as to block heat generated from the multiple LED elements from being transmitted in a direction perpendicular to the opposite surface. Accordingly, the insulation sheet can minimize vertical transfer of received heat as well as reducing the heating level of the multiple LED elements, and is thus advantageous in minimizing or preventing heat transfer in an undesirable direction and/or of an undesirable amount.
