Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In the field of display technology, there are many process steps required to attach a product in the process of forming a display screen body. For example, a guide film is generally used in a process of attaching a touch-sensitive flexible printed wiring board. Under the influence of the tension of the guide film, the process equipment (such as a 3D laminating machine) excessively bears the force or unevenly bears the force in the process of bending and pulling down the screen body to be laminated. Therefore, the TP FPC and the COF (Chip on Film) are easily pulled downward during the lamination process of the touch panel, the TP FPC and the COF are damaged, and the lamination yield of the touch flexible printed circuit board is reduced. Because the laminating yield of touch-control flexible printed circuit board reduces, consequently, there is the flexible display product disability rate height, and the output yield is low, the extravagant problem of manpower man-hour, screen body and material.
The inventor of the application provides a touch panel attaching method and a display panel. By adopting the guide film and the touch panel laminating method provided by the application, the touch yield of the laminated touch panel can reach 100%.
Please refer to fig. 1 to 4 to understand the display panel 10 and the touch panel bonding method provided in the present application. The display panel 10 includes a screen body 100 to be attached and a touch panel. The touch panel comprises a touch flexible printed wiring board TP FPC, which is part of the structure of the display panel 10. The touch panel attaching method provided in the present application is a method of attaching the touch panel to the screen body 100 to be attached to form the display panel. Referring to fig. 1, the present application provides a touch panel attaching method, including:
and S100, providing the screen body 100 to be attached and the guide film 400. The screen body to be attached 100 has a first surface 111 and a second surface 112.
The screen body 100 to be attached in this step may include a substrate, a thin film transistor TFT, an organic light emitting diode OLED, and an encapsulation module TFE. Referring to fig. 2, a top view of the to-be-bonded panel 100 shows that the to-be-bonded panel 100 includes a base film layer region 110 and an electrical connection region 120. No metal leads or electrical connection leads are exposed at the base film region 110. The base film region 110 may include a display region and a bezel region beside the display region. The electrical connection region 120 may include a bonding region, and a printed circuit board, a flexible printed circuit board, a driver chip board, or a touch chip board externally connected through the bonding region. The guide film 400 in this step belongs to a process structure in the process of bonding the display panel 10, and is used for assisting process equipment in realizing a bonding process of a touch panel.
S200, attaching the guide film 400 to the second surface 112 without the guide film 400 directly contacting the electrical connection assembly 130.
In this step, please refer to fig. 3 and fig. 4, the guiding film 400 is attached to the second surface 112. The second surface 112 is a surface of a substrate in the screen body 100 to be attached. The substrate base plate may be a flexible and bendable substrate base plate. The surface of the guide film 400 attached to the substrate (i.e., the second surface 112) can fix the screen body 100 to be attached. The guide film 400 may be matched with a 3D bonding process device, so that the touch panel is bonded to the first surface 111 of the screen body 100 to be bonded, so as to implement a bonding process of the touch panel.
The electrical connection member 130 may include a touch flexible printed circuit board (TP FPC) and a driving control Chip (COF). The TP FPC may enable control of the touch electrodes in the touch panel 300. COF realizes the drive control of OLED display. The guide film 400 does not directly contact the electrical connection assembly 130, so that the electrical connection structure of the TP FPC and COF regions is not affected by a bending pull-down force during the 3D bonding process. The electrical connection structure in the electrical connection assembly 130 does not follow the bending amplitude of the 3D laminating machine, so that the TP FPC and COF can shift by themselves.
S300, providing a touch panel 300, and attaching the touch panel 300 to the first surface 111.
In this step, the touch panel 300 may be attached to the first surface 111 by means of a 3D attaching process device. In the process of attaching the touch panel 300, the guide film 400 fixes the screen body 100 to be attached, and the structure of the first surface 111 of the screen body 100 to be attached is aligned with the structure of the touch panel 300 accurately.
S400, separating the guide film 400 from the to-be-bonded panel 100 to complete bonding of the display panel 10.
In this step, the guide film 400 is separated from the screen body 100 to be attached. Since the electrical connection assembly 130 in the screen body 100 to be attached leaks out during the process of attaching the guide film 400 to the second surface 112, when the guide film 400 is separated, the electrical connection structure of the electrical connection assembly 130 is not damaged.
In this embodiment, when the guide film 400 is attached to the second surface 112, it can be ensured that the guide film 400 does not directly contact with the electrical connection assembly 130. The electrical connection structure in the electrical connection assembly 130 does not shift along with the bending amplitude of the 3D laminating machine. The electrical connection structure in the electrical connection assembly 130 is not damaged when the guide film 400 is separated. The touch panel attaching method provided in this embodiment can avoid the problem of pulling the electrical connection structure in the electrical connection assembly 130. Through process verification, the display panel 10 prepared by the touch panel attaching method provided in the embodiment does not find the malfunction of the touch panel 300, and the yield of the prepared display panel 10 is 100%.
Referring to fig. 5, in one embodiment, the step S400 of attaching the guide film 400 to the second surface 112 without the guide film 400 directly contacting the electrical connection assembly 130 includes:
according to the structure of the screen body 100 to be attached, the guide film 400 is cut so that the electrical connection assembly 130 leaks when the guide film 400 is attached to the second surface 112.
In this embodiment, the guiding film 400 is cut to be consistent with the structure of the base film layer 110 in the to-be-attached screen 100, so as to realize a state that the guiding film 400 is not in direct contact with the electrical connection assembly 130. The purpose of the guiding film 400 leaking out of the electrical connection region 120 is to prevent the guiding film 400 from pulling on the electrical connection region 120 during the attaching process, which may eventually cause the electrical connection assembly 130 to fail. As can be seen in fig. 5, the hollow-out area in fig. 5 directly corresponds to the electrical connection area 120. The hollow area of the guide film 400 is cut out. The hollow area of the guide film 400 corresponds to the electrical connection assembly 130, and the guide film 400 does not damage the electrical connection assembly 130 in the process of the bonding process.
Referring to fig. 6, in an embodiment, the screen body to be attached 100 includes a base film region 110 and an electrical connection region 120. The guide film 400 includes: a body film layer 410 and a bonding glue layer 420. The body film layer 410 is aligned to cover the base film layer region 110 and the electrical connection region 120, and the body film layer 410 is a transparent film layer. The bonding glue layer 420 is only aligned with the base film region 110.
The step S200 of attaching the guide film 400 to the second surface 112 without the guide film 400 directly contacting the electrical connection assembly 130 includes:
the guide film 400 including the body film layer 410 and the adhesive layer 420 is attached to the second surface 112, and the adhesive layer 420 is only aligned with the base film layer 110, so that the electrical connection assembly 130 leaks out when the guide film 400 is attached to the second surface 112.
In this embodiment, the structure of the guide film 400 is improved to achieve the effect that the guide film 400 is not directly contacted with the electrical connection component 130, so as to ensure the yield of the touch panel 300 in the attaching process and improve the yield of the display panel 10. Specifically, the guide film 400 includes: a body film layer 410 and a bonding glue layer 420. The body film layer 410 is in registration covering the base film layer region 110 and the electrical connection region 120. The body film layer 410 is a transparent film layer. The bonding glue layer 420 is only aligned with the base film region 110. The adhesive layer 420 may be a UV adhesive or other adhesive capable of adhering and fixing.
In one embodiment, the body film layer 410 is polyethylene terephthalate, and the thickness of the body film layer 410 is 15 to 65 micrometers. The body film layer 410 can also be replaced by any antistatic flexible film with a PI film or a UV light transmittance. Preferably, the thickness of the bulk film layer 410 is 45 to 65 microns. The thickness reduction of the body film layer 410 can enable the attaching precision to be higher in the attaching guiding process, and the guiding film 400 causes less damage to the screen body 100 to be attached.
In this embodiment, the Polyethylene terephthalate is known by its english name as Polyethylene terephthalate, PET for short. The PET material has good mechanical property, the impact strength is 3-5 times that of other films, and the folding resistance is good. The PET material can also resist oil, fat, olefine acid, dilute alkali and most solvents. The PET material also has excellent high and low temperature resistance, can be used for a long time within the temperature range of 120 ℃, can resist high temperature of 150 ℃ and low temperature of-70 ℃ in short time, and has little influence on the mechanical properties of the PET material at high and low temperatures. The PET material has low gas and water vapor permeability, and has excellent gas, water, oil and odor barrier properties. The PET material has high transparency, can block ultraviolet rays and has good glossiness. Applying the PET material to the body film layer 410 may make the guide film 400 more advantageous in achieving the fitting process.
In one embodiment, the guide film 400 further includes a transparent release film and an antistatic coating layer, which are laminated, and are disposed adjacent to the adhesive layer 420.
Specifically, in this embodiment, the guide film 400 may include the body film layer 410, the adhesive layer 420, a transparent release film (not shown), and an antistatic coating (not shown) sequentially stacked. In one embodiment, the material of the bulk film layer 400 is antistatic transparent PET with a thickness of 50 microns. The adhesive layer 420 is an antistatic UV debonding adhesive with a thickness of 15 microns. The thickness of the transparent release film is 50 micrometers. The thickness of the antistatic coating was 5 microns. Before the 3D laminating, the guide film 400 may include the body film layer 410, the laminating adhesive layer 420, the transparent release film, and the antistatic coating layer, which are sequentially stacked. In the 3D attaching process, the transparent release film and the antistatic coating of the guide film 400 are peeled off, so that the attaching glue layer 420 and/or the body film layer 410 directly contact the screen body 100 to be attached.
In one embodiment, the area of the guide film 400 is larger than the area of the panel 100 to be attached, so that when the guide film 400 is attached to the second surface 112, the structures of the panel 100 to be attached except the electrical connection assembly 130 are covered by the guide film 400.
In this embodiment, the guide film 400 having a large area may be provided according to actual bonding requirements, so as to avoid frequent replacement of the guide film 400 in the process of mass production of the display panel 10.
Referring to fig. 6, in an embodiment, the body film layer 410 further has an auxiliary action area 411 for an area outside the screen body 100 to be attached. The auxiliary motion area 411 is used to provide a manual or mechanical operation structure, so as to facilitate the separation of the guide film 400 from the screen body 100 to be attached.
The step S400 of separating the guide film 400 from the to-be-bonded panel 100 to complete bonding of the display panel 10 includes:
fixing the screen body 100 to be attached and the touch panel 300, and applying a separating force to the auxiliary action area 411 of the guide film 400, so that the guide film 400 is separated from the screen body 100 to be attached.
In this embodiment, the auxiliary motion area 411 is used to provide a manual or mechanical operation form, so as to facilitate the separation of the guide film 400 from the screen body 100 to be attached. In this embodiment, the auxiliary operation area 411 is used to separate the guide film 400 from the screen body 100 to be attached, so as to improve the yield in the separation process and simplify the separation process. The area of the auxiliary operation region 411 may be adjusted according to actual process requirements, and the auxiliary operation region 411 may be disposed to prevent the guide film 400 from being broken during the separation process.
