[0002] At present, mobile phone display modules will encounter three situations: 1. In order to shield the interference of FPC wiring signals on the RF signals of the mobile phone host, single-conductor copper foil tape will be attached to the dense FPC wiring for signal shielding; 2. Mobile phone display modules usually adopt the method of attaching conductive double-sided adhesive to stick the exposed copper connection position of the main screen FPC to the backlight iron frame for grounding; 3. In order to block the light leakage on the top side of the backlight, a piece of shading paper will be attached to the top side of the backlight.

[0040] Example 1

[0041] Please refer to Figure 1-4A hybrid film roll structure includes a roll structure 1, a conductive double-sided adhesive 2, a single-conductive copper foil tape 3 and a shading paper 4. The conductive double-sided adhesive 2 is adhered to a first heavy release film 5. The single-conductive copper foil tape 3 includes a first insulating tape 31, a copper foil 32 and a second insulating tape 33 from bottom to top, and the whole is adhered to a second heavy release film 6. The shading paper 4 is adhered to a third release film 7. The first heavy release film 5, the second heavy release film 6 and the third release film 7 are all arranged in sequence on the roll structure 1 in a circular manner.

[0042] Through the above-mentioned structural design, the roll structure 1 is used as the incoming material, and the single-conductive copper foil tape 3, the conductive double-sided adhesive 2 and the shading paper 4 are all arranged in sequence on the roll structure 1 in a circular manner. Only a heavy release film needs to be provided for each of them, which saves the use of a light release film.
