Technical field
The present invention relates to OLED field of display technology, refer in particular to a kind of preparation method of flexible display panels.
Background technique
Flexible display panels also known as crimp display panel, be visual flexible panel is made with flexible material and constitute can
The display device of bending deformation.Flexible display panels have broad prospects, and become the focus of major panel manufacturer's competition.
The production method of the flexible OLED display panel of mainstream is at present: using glass substrate as carrier, on whole face glass
It is coated with strata acid imide (PI) film, PI film is solidified, PI film serves as flexible base board, then up successively makes from PI film
Tft layer, OLED device layer and thin-film encapsulation layer, so obtain flexible OLED display panel.Finally by Flexible Displays
Panel is stripped down from glass substrate.However the lift-off technology of flexible display panels and glass substrate is failed always to obtain very
It is good as a result, being easy to cause biggish damage to PI film.
Currently used stripping means substantially has several: laser lift-off technique is used, however required for laser lift-off
Energy is high, its cost is also high, and since the high-energy of laser be easy to cause the damage of luminescent device.Or added using resistance
Thermoinduction lift-off technology, which be detached from flexible display and glass substrate using the method for heating, however the resistance
Incude lift-off technology in stripping process, temperature is excessively high, biggish damage can be caused to PI film, while need to luminescent device into
Row protection, rises manufacturing cost.Or chemical stripping method is used, flexible display panels are shelled using the corrosivity of chemical liquid
From getting off, but the corrosivity of chemicals and acid-base property also will be greatly reduced the service life of flexible display.
