Erosion, the thin-film encapsulation layer can be formed by stacking by inorganic layer, organic layer, inorganic layer three-layer thin-film.
White light OLED can be used in the OLED luminescent layer, and monochromatic luminous organic electroluminescence device, this reality can also be used
It applies and selects single color light emitting devices in example, in order to reduce light loss, the color of the color blocking layer in the coloured silk film layer 14 need to be with OLED function
Corresponding pixel color on ergosphere is identical, i.e., the red, green, blue color blocking block in the described color film layer 14 respectively with the array substrate
Red, green, blue sub-pixel unit on 11 is arranged in a one-to-one correspondence.
As shown in figure 5, the production method of the flexible display panels, further includes the production of touch function layer, in array base
Touch control layer 12 is formed on plate 11, the touch control layer 12 includes touch control electrode, specifically, depositing gold in the thin-film encapsulation layer
Belong to, and driving touch control electrode and induction touch control electrode are formed by Patternized technique.It in addition to this, can also be by touch function layer list
Solely preparation forms touch control layer 12 on substrate, then is bonded by optical cement with array substrate 11.
As shown in figure 5, the present invention also provides a kind of flexible display panels 10 prepared using the above method, comprising: array
Substrate 11, adhesive layer 13, color film layer 14 and covering window 15.
Wherein, the adhesive layer 13 is set in the array substrate 11, and the coloured silk film layer 14 is set to the adhesive layer
On, the covering window 15 is set in the color film layer.
The array substrate 11 includes setting gradually tft layer on flexible substrates, OLED luminescent layer and thin
Polyimide material preparation can be used in film encapsulated layer, the flexible base board.
Include multiple pixel units in the array substrate 11, includes multiple red, green, blue colors in the coloured silk film layer 14
Resistance layer, the color blocking layer are corresponding with the red, green, blue sub-pixel unit in the array substrate 11 respectively.
The flexible display panels 10 further include touch control layer 12, and the touch control layer is set to the color film layer 14 and the battle array
Between column substrate 11, the touch control layer is to realize touch function.
The utility model has the advantages that the production method of flexible display panels provided by the invention, first by color film preparation on covering window, then
It is bonded together with covering window with array substrate, by changing the production order of color film, avoids preparing directly in OLED device color
Film, and then influence of the color film processing procedure to OLED luminescent layer is avoided, to improve the yield of flexible display panels.
In conclusion although the present invention has been disclosed above in the preferred embodiment, but above preferred embodiment is not to limit
The system present invention, those skilled in the art can make various changes and profit without departing from the spirit and scope of the present invention
