Title:
HEAT DISSIPATION FILM, DISPLAY MODULE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/105481
Kind Code:
A1
Abstract:
A heat dissipation film, a display module, and an electronic device, relating to the field of displays. The heat dissipation film comprises an elastic cushioning layer (10), a heat dissipation layer (20), and an isolation layer (30). The elastic cushioning layer (10) has a first fingerprint hole (101), the heat dissipation layer (20) has a second fingerprint hole (201), and an orthographic projection of the first fingerprint hole (101) on a first side surface (11) is located in an orthographic projection of the second fingerprint hole (201) on the first side surface (11). The isolation layer (30) is located on the first side surface (11) of the elastic cushioning layer (10), the isolation layer (30) has a third fingerprint hole (301), the orthographic projection of the first fingerprint hole (101) on the first side surface (11) at least partially overlaps with an orthographic projection of the third fingerprint hole (301) on the first side surface (11), and the surface of the isolation layer (30) distant from the first side surface (11) is non-adhesive. The isolation layer (30) is located between a fingerprint module (70) and the elastic cushioning layer (10), and the surface of the isolation layer (30) facing the fingerprint module (70) is non-adhesive. When a screen of a display panel is pressed, even if the display panel deforms to drive the elastic cushioning layer and the isolation layer to deform so that the isolation layer is in contact with the fingerprint module, the isolation layer is not adhered to the fingerprint module; after the isolation layer recovers from deformation, the electronic device does not produce sound.
