Title:
DISPLAY DEVICE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/155472
Kind Code:
A1
Abstract:
A display device and a manufacturing method therefor. The display device comprises a display panel (10) and a functional film layer (20); the functional film layer (20) comprises a substrate (21), a drive electrode (22) provided on the substrate (21), and a cleaning film layer (23) covering the drive electrode (22); the cleaning film layer (23) comprises polar liquid crystal molecules bearing acrylate groups, and the drive electrode (22) provides an alternating-current electric field for the polar liquid crystal molecules. Under the action of the alternating-current electric field, the surface of the cleaning film layer changes with the change of the alternating-current electric field, generating a surface vibration similar to a macroscopic vibration, so as to achieve the effect of cleaning, so that the interior and exterior of a display device can be cleaned. Said display device can be used outdoors or in water-stressed regions having an arid climate, while being not limited by a cleaning tool, being convenient and efficient, and environmental friendly, being not harmful to a human body, and being able to avoid damage to precision parts in the display device.
