Abstract
A high-temperature resistant liquid crystal protecting film consists of a PET (Polyurethane) protective stripping layer 1, a PET use layer 2 and a PET stripping film 3, wherein the PET use layer 2 comprises an UV (Ultraviolet) scratching resistant coating 21, a PET low-viscosity protecting film 22 and a high-temperature resistant silica gel coating 23; the upper surface of the PET use layer 2 is coated with the UV scratching resistant coating 21; and the lower surface of the PET use layer 2 is coated with the high-temperature resistant silica gel coating 23. The UV scratching resistant coating 21 is attached to the upper surface of the PET low-viscosity protecting film 22 and cured by irradiation of an ultraviolet lamp so as to generate a certain rebound elasticity and further the functions for preventing collision and scratch to a display screen are achieved; and the lower surface of the PET low-viscosity protecting film 22 is coated with the high-temperature resistant silica gel coating 23 and used for being bonded with the protected display screen.
Description
Technical field
The utility model relates to a kind of diaphragm, refers in particular to such an extent that be a kind of resistant to elevated temperatures liquid crystal diaphragm.
Background technology
The diaphragm of LCD, it is mainly constructed and haves three layers, and ground floor PET protects stripping film, and the second layer is the low sticking diaphragm of PET (using layer), and the 3rd layer is PET stripping film (ground).The low sticking diaphragm of the PET of its second layer (using layer) is divided into 3 layers again: ground floor is the scratch resistant coating of UV, and its key effect is not scratched for the protection display; The second layer is the PET film, is the basic unit of diaphragm; The 3rd layer is silica gel layer, and it mainly act as and lets the PET film, and promptly basic unit can paste or be adsorbed onto LCD Panel automatically.High temperature resistant, the poor-performing of anti-high humidity of existing liquid crystal diaphragm, its main cause is the liquid silica gel that silica gel layer is used for the general industry standard, and liquid silica gel easily under hot and humid environment in the generation physicochemical change.Can reach 60 degree centigrade in silica gel environment for use temperature summer, and under the extreme environment of this hot and humid sealing, sex change just takes place the silica gel layer during liquid crystal protection is pasted, multiple bad phenomenon such as flavescence usually takes place even come unstuck.
In order to solve the problem that exists in the above technology, the utility model has been made following technical solution.
The utility model content:
Like Fig. 1, the utility model uses layer 2 and PET stripping film 3 to form by PET protection stripping film 1, PET, and PET uses layer 2 to comprise the scratch resistant coating of UV 21, low diaphragm 22, the high temperature resistant silicon gel coating 23 of gluing of PET.
On the liquid crystal diaphragm, be designed with PET protection stripping film 1, below the liquid crystal diaphragm, be designed with PET stripping film 3, this two-layer stripping film is not use some surfacecti proteons of previous crops at the PET diaphragm, and the liquid crystal diaphragm is played a part dustproof and anti-scratch.In the time will using the PET diaphragm, at first to remove PET protection stripping film 1 and PET stripping film 3 these two-layer protecting films.Use the upper surface of layer 2 to scribble the scratch resistant coating 21 of UV at PET, this coating is attached to the upper surface of the low sticking diaphragm 22 of PET, and the irradiation through ultraviolet light is cured, and produces certain bounce-back retractility, and display screen is played a part to prevent to collide and scratch.PET is low, and sticking diaphragm 22 is use layers of liquid crystal diaphragm, is coated with the scratch resistant coating 21 of UV above it, is used for preventing the pollution and the scratch of foreign object; Be coated with high temperature resistant silicon gel coating 23 below, be used for carrying out bonding and absorption with protected display screen.
The beneficial effect of the utility model is at hot and humid China's southern area; Use the diaphragm of high temperature resistant dedicated liquid silica gel coating; The high light transmittance that not only can keep original PET diaphragm; Can also the hot and humid adverse circumstances of Nai Chenei, prevent that silica gel layer from because of sex change produces yellowing, fuel-displaced, phenomenon such as come unstuck, having improved traveling security.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the PET of the utility model uses layer structural representation.
Fig. 3 is the silica gel coating layer sketch map of the utility model.
The specific embodiment:
Like Fig. 1, the utility model uses layer 2 and PET stripping film 3 to form by PET protection stripping film 1, PET.PET uses layer 2 to comprise the scratch resistant coating of UV 21, the low sticking diaphragm 22 of PET, high temperature resistant silicon gel coating 23.
Like Fig. 2-3;, PET is coated with the scratch resistant coating 21 of last layer UV on using layer 2; Applying one deck PET protection stripping film 1 on the scratch resistant coating 21 of UV; Below PET uses layer, be coated with last layer silica-gel coating 23, applying one deck PET stripping film 3 has just formed high temperature resistant liquid crystal protection subsides below high temperature resistant silicon gel coating 23.
Claims (2)
1. resistant to elevated temperatures liquid crystal diaphragm; Use layer and PET stripping film to form by PET protection stripping film, PET; PET uses layer to comprise the scratch resistant coating of UV, the low sticking diaphragm of PET, high temperature resistant silicon gel coating; It is characterized in that using the upper surface of layer to scribble the scratch resistant coating of UV, be coated with the high temperature resistant silicon gel coating below at PET.
2. by the described a kind of resistant to elevated temperatures liquid crystal diaphragm of claim 1, it is characterized in that the upper surface of the scratch resistant coating of UV, below the low sticking diaphragm of PET, scribble the high temperature resistant silicon gel coating attached to the low sticking diaphragm of PET.
