Problems solved by technology

[0004] -silicon, low-temperature polysilicon), and the Z-axis direction of the Encap (encapsulation, packaging substrate) layer has a step difference, so it is easy to crack or break at the chamfered corner or the middle IC position. The simple buffer layer (Padding Tape) cannot affect the AMOLED display panel. The side edges and the OLB area play a very good protective role, affecting the structural strength and service life of the AMOLED display panel, which is what those skilled in the art do not want to see

Embodiment 1

[0042] Such as figure 2 and image 3 As shown, this embodiment relates to an AMOLED display panel structure, which includes an AMOLED display panel 1 and an outer pin bonding area mechanism 2 arranged on the first side edge of the AMOLED display panel; Adhesive 3 is poured into other side edges other than the edge and the outer lead attaching area mechanism 2, so as to increase the strength of the AMOLED display panel structure.

[0043] In a preferred embodiment of the present invention, the above-mentioned adhesive 3 is ultraviolet glue (UV glue) or silica gel; among them, ultraviolet glue is also called photosensitive glue, ultraviolet light curing glue, and it is a kind of glue that must be irradiated by ultraviolet light to be cured. A type of adhesive that can be used as a bonding agent. Specifically, UV is the abbreviation of Ultraviolet Rays in English, that is, ultraviolet light with a wavelength in the range of 110-400nm. The principle of UV glue curing is that t...

Embodiment 2

[0052] This embodiment relates to a method for preparing an AMOLED display panel structure, and the method specifically includes:

[0053] In step S1, an AMOLED display panel is provided, and the AMOLED display panel includes a package substrate and a polarizer disposed on the package substrate.

[0054] Step S2 , forming an outer pin bonding area mechanism on the first side edge of the AMOLED display panel.

[0055] In a preferred embodiment of the present invention, step S2 specifically includes:

[0056] Step S21 , attaching a protective film on the first side edge of the AMOLED display panel, the protective film fills the height difference between the packaging substrate and the polarizer, and the protective film avoids the bonding area of ​​the touch panel.

[0057] Step S22 , attaching a buffer layer to the side edge of the protective film along the bottom edge of the packaging substrate.

[0058] In a preferred embodiment of the present invention, the buffer layer inc...

Abstract

The invention relates to the field of display, and especially relates to an AMOLED display panel structure and a preparation method therefor. Ultraviolet glue or silica gel is poured at the edge of aside surface of an AMOLED display panel and an external pin gluing region mechanism, thereby preventing the invasion of water vapor, and, more importantly, buffering the impact when a cellphone falls,effectively solving problems of edge breakage and corner breakage of the AMOLED display panel and the crack and breakage of the external pin gluing region mechanism, improving the structural strengthof the AMOLED display panel, and prolonging the service life of the AMOLED display panel.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to an AMOLED display panel structure and a preparation method thereof. Background technique [0002] OLED is an Organic Light-Emitting Diode (Organic Light-Emitting Diode), which has the characteristics of self-illumination, high brightness, wide viewing angle, high contrast, flexibility, and low energy consumption. It began to gradually replace traditional liquid crystal displays and was widely used in mobile phone screens, computer monitors, full-color TVs, etc. [0003] At present, because the AMOLED display panel will be bumped or hit when the whole machine is dropped, the edge of the AMOLED display panel is prone to edge chipping and corner chipping. The Outer Lead Bonding (OLB) is only a single-layer LTPS ( low temperature poly [0004] -silicon, low-temperature polysilicon), and the Z-axis direction of the Encap (encapsulation, packaging substrate) layer has a step differe...
