Description
Technical field
The present invention relates to display technology field, specifically, the present invention relates to Flexible Displays cover board and preparation method thereof, display
Device.
Background technology
At present, Flexible Displays are faced with bending performance and the dual huge challenge of mechanical performance with cover board.Generally, it is flexible aobvious
Show with cover board to be typically that can not have preferable bending performance and stronger case hardness and shock resistance concurrently, using flexible thin
Film and its surface set the structure of superhard hardened layer, and Flexible Displays cover board can only be made to possess preferable bending performance (crooked process radius
3mm), but its shock resistance effect is still poor.Also, this Flexible Displays covering plate structure can not also be to Flexible Displays cover board below
Device form good shock resistance protection, specifically refer to Fig. 1, under external force percussion, stress is in display cover board
(Cover) surface is transmitted around, is caused the easy fragmentation in Cover surfaces and is produced open defect, in addition stress can not also at the same time
Break and device is transmitted and be corrupted to device lower end.
Therefore, the structure of Flexible Displays cover board at this stage still has much room for improvement.
The content of the invention
It is contemplated that solve at least some of the technical problems in related technologies.
The present invention is the following discovery based on inventor and completes：
Present inventor has found in the course of the research, in traditional Flexible Displays cover board (Flexible Cover),
As external impacts Flexible Cover, with reference to figure 1, external force can produce Flexible Cover the destruction of both direction
Power, one are in hardening 200 lateral transport of (Hard coating) layer, so as to cause Hard coating layers 200 to crack and draw
The open defect risen, secondly being transmitted to continue longitudinal direction through Hard coating layers 200, so as to cause under Flexible Cover
Partial display device is subject to stronger external impacts to act on and destroyed generation defect.
So present inventor in fexible film (Flexible substrate) first surface by increasing anti-impact
The hardened layer hit, the hardened layer are made of multiple minor structures spaced apart, can so block the destructive power of lateral transport, and
Two surfaces increase the structure of stress absorbing layer, for absorbing the destructive power longitudinally transmitted, so as to cause Flexible Displays cover board
