Embodiment Construction

[0033] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0034] see figure 2 , the invention provides a method for manufacturing a flexible OLED panel, comprising the following steps:

[0035] Step 1, providing a rigid substrate 20 and a flexible substrate 40 .

[0036] In this embodiment, the rigid substrate 20 is a glass substrate.

[0037] Step 2, forming a metal layer 22 on the periphery of the rigid substrate 20 .

[0038] see image 3 A metal layer 22 is formed on the periphery of the rigid substrate 20, and the metal layer 22 is formed of a metal with a high resistivity. When the width, thickness and length are consistent, the greater the resistivity of the metal, the greater the resistance, and the greater the resistance , when energized, more heat is generated, which can effectively sh...

Abstract

The invention provides a manufacturing method of a flexible OLED panel. The manufacturing method includes the steps that step1, a rigid substrate (20) and a flexible substrate (40) are provided; step2, a metal layer (22) is formed on the periphery of the rigid substrate (20); step3, a supporting layer (24) is formed on the inner side of the metal layer (22); step4, the flexible substrate (40) is placed on the rigid substrate (20); step5, voltage is exerted on the metal layer (22) to heat the flexible substrate (40), so that material of the flexible substrate (40) making contact with the metal layer (22) reaches a melting point, and the flexible substrate(40) and the rigid substrate (20) adhere together; step6, an OLED element (42) is formed on the flexible substrate (40) and packaged; step7, voltage is exerted on the metal layer (22) to heat the flexible substrate (40), and after the material of the flexible substrate (40) making contact with the metal layer (22) reaches the melting point, the flexible substrate (40) and the rigid substrate (20) are separated.

Description

technical field [0001] The invention relates to the field of flat display, in particular to a method for manufacturing a flexible OLED panel. Background technique [0002] The flat panel display device has many advantages such as thin body, power saving, and no radiation, and has been widely used. Existing flat panel display devices mainly include liquid crystal displays (Liquid Crystal Display, LCD) and organic light emitting displays (Organic Electroluminescence Device, OELD), also known as organic light emitting diodes (Organic Light Emitting Diode, OLED). [0003] The existing liquid crystal display is generally a backlight type liquid crystal display, which includes: a casing, a liquid crystal display panel disposed in the casing, and a backlight module (Backlight Module) disposed in the casing. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates, and apply a driving voltage on the two gla...
