Embodiment Construction

[0034] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail the preferred embodiments of the present invention and the accompanying drawings.

[0035] See figure 1 , The present invention provides a method for manufacturing a flexible OLED display panel, including the following steps:

[0036] Step 1, such as figure 2 versus image 3 As shown, a rigid substrate 10 is provided. On the rigid substrate 10, several circles of inorganic barrier walls 20 are formed at intervals, and the several circles of inorganic barrier walls 20 enclose several panel areas 11 on the rigid substrate 10.

[0037] Specifically, the rigid substrate 10 is a glass substrate.

[0038] Specifically, the material of the number-turn inorganic retaining wall 20 includes silicon oxide (SiO x ), silicon nitride (SiN x ), and silicon oxynitride (SiO x N x ) At least one of.

[0039] Preferably, the material of the inorganic retaining wal...

Abstract

The invention provides a manufacturing method of flexible OLED (Organic Light Emitting Diode) display panels. The method comprises the following steps: firstly forming a plurality of circles of inorganic retaining walls on a rigid substrate, wherein a plurality of panel areas are defined on the rigid substrate by the plurality of circles of inorganic retaining walls, and thus a plurality of flexible substrates are directly formed on the plurality of panel areas on the rigid substrate respectively by using segmentation effects of the plurality of circles of inorganic retaining walls when the rigid substrate and the plurality of circles of whole inorganic retaining walls are coated with organic material films; subsequently stripping the plurality of flexible substrates off from the rigid substrate by using a laser stripping technique to obtain a plurality of flexible OLED display panels. Compared with the prior art, the process of simultaneously cutting the organic material films and the rigid substrate by using a laser cutting machine table is eliminated; the purchase cost of the laser cutting machine table is reduced while a laser cutting process is eliminated, so that the manufacturing cost of the flexible OLED display panels is reduced.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a manufacturing method of a flexible OLED display panel. Background technique [0002] Organic Light Emitting Display (OLED) has self-luminescence, low driving voltage, high luminous efficiency, short response time, high definition and contrast, close to 180° viewing angle, wide operating temperature range, and can realize flexible display and Large-area full-color display and many other advantages are recognized by the industry as the display device with the most development potential. [0003] According to the driving mode, OLED can be divided into passive matrix OLED (Passive Matrix OLED, PMOLED) and active matrix OLED (Active Matrix OLED, AMOLED), namely direct addressing and thin film transistor matrix addressing. Among them, AMOLED has pixels arranged in an array, is an active display type, has high luminous efficiency, and is generally used as a high-definition large-si...
