The present embodiment to this and it is without restriction, as long as guarantee it is corresponding with the pixel color of luminescence unit 40.
It is important to note that optical filter provided in this embodiment allows the color of transmitted light and corresponding luminous list
The luminescent color of member is identical, and such setting can guarantee, when ambient lighting penetrates the surface in flexible display panels, with optical filtering
The identical light of piece color can just enter the inside of flexible display panels by optical filter, strong after light color is filtered out
Degree will certainly weaken, therefore can use optical filter and weaken the intensity for entering the environment light inside flexible display panels.Further
Ground, the light after flexible display panels internal reflection can be again through optical filter, intensity when projecting flexible display panels
It can be weakened again, therefore the optical filter can also weaken the intensity for reflecting the environment light of flexible display panels, to improve
The contrasts that flexible display panels itself shine with environment light, enhance the display effect of flexible display panels.
Meanwhile allowing the color of transmitted light identical as corresponding luminescence unit luminescent color based on optical filter, therefore filter
The light that mating plate can't issue flexible display panels itself has an impact, and ensure that the display effect of flexible display panels.
Specifically, in order to further reduce reflected intensity of the environment light in flexible display panels, the back of filter layer 50
The side of underlay substrate 10 is provided with light-absorption layer 60, the not set opening of light-absorption layer 60 and pixel confining layer 30

It is a variety of.
As a kind of achievable embodiment, light-absorption layer 60 with a thickness of 10-300nm.The thickness of light-absorption layer 60 is excessive,
Meeting is unfavorable for the folding and distortion of flexible display panels so that the entirely thickness increase of flexible display panels.And work as light-absorption layer
When 60 thickness is too small, and it will affect the extinction effect of light-absorption layer 60.As a preferred embodiment, the thickness of light-absorption layer 60
Degree can be 10-150nm.Actual in use, user can according to need selectes light-absorption layer 60 in above-mentioned range
Specific thickness value, the present embodiment is to the specific thickness value of light-absorption layer 60 and without restriction.
As a kind of achievable embodiment, flexible display panels can be arranged in light-absorption layer 60 by way of bonding
In, for example, can filter layer 50 backwards to and/or transparent optical adhesive layer is set towards the side of underlay substrate 10, and will inhale
Photosphere 60 is fixed in optical adhesive layer, and optical adhesive layer can not only play the purpose of fixed light-absorption layer 60, can also be to light-absorption layer
60 provide protective effect.
Further, interior with multiple extinction ducts 61 based on light-absorption layer 60, therefore can play the role of discharging stress,
When flexible display panels fold or are bent, the structure sheaf of 60 two sides of light-absorption layer, such as pixel confining layer 30 and filter layer 50,
Or the stress generated between filter layer 50 and encapsulated layer (not shown) can be transferred to light-absorption layer 60, it is multiple in light-absorption layer 60
Extinction duct 61 forms reticular structure, and stress can transmit on the grid lines of reticular structure, so that stress is evenly distributed on suction
It in photosphere 60, avoids stress build up in pixel confining layer 30, filter layer 50 or encapsulated layer, avoids breaking in the layer of recurring structure layer
