Problems solved by technology

[0003] This type of product can only be applied to print advertisements and decorations pasted on the surface of glass materials, so there is a singleness in the advertisements made of this type of material, and it cannot play the effect of advertisement decoration in dark places, and cannot be used as a one-way LED display screen. See-through printing materials, and it is impossible to replace the display content through the change of the LED display screen, which brings obvious defects of different visual effects day and night, and there are obvious limitations in the scope of use.

Embodiment 1

[0017] See attached figure 1 , 2 , the one-way see-through printing material for LED display consists of the upper printing substrate layer 1 using white PVC film and the lower layer using black PVC film as the bottom layer 2, which is laminated by heating. The white PVC film is used as the printing substrate layer 1, and the black PVC film The film is used as the bottom layer 2, and a layer of transparent acrylic pressure-sensitive adhesive is coated on the surface of the bottom layer 2 as the glue layer 3, so that the bottom layer 2 and the opaque paper layer 4 are bonded by the glue layer 3, and the entire surface Through-holes 5 are perforated in a square arrangement in the vertical direction. The diameter of the through-holes 5 is Φ4.5mm, and the hole spacing is 15mm. The paper layer 4 sticks the one-way transparent film on the LED display screen, and the through hole 5 exposes the LED light-emitting diode, which is used for advertising and marking day and night.

Embodiment 2

[0019] See attached figure 1 , 2 , use white PVC film as the printing substrate layer 1, and coat a layer of black pressure-sensitive adhesive layer on the surface of the printing substrate layer 1 as the bottom layer 2 to form a one-way perspective film, and then use the black pressure-sensitive adhesive layer as the glue on the bottom layer 2 Layer 3 is pasted with a layer of opaque paper layer 4, and through-holes 5 are perforated in the vertical direction of the entire sheet in a square arrangement. The diameter of the through-holes 5 is Φ4.5mm, and the hole distance is 30mm. The film printing substrate layer 1 sprays graphics and text, removes the opaque paper layer 4, and sticks the one-way see-through film on the LED display screen. The through hole 5 reveals the LED light-emitting diode, which is used for advertising and marking day and night.

Abstract

The invention relates to a unidirectional-transparent printing material used in an LED display screen. According to the invention, an upper printing substrate layer and a lower coated bottom layer are composed into a unidirectional-transparent film with a heat composition method. The coated bottom layer and a light proof paper layer are bonded by using an adhesive layer, or a layer of black glue is coated on the surface of the printing substrate layer, such that a unidirectional-transparent film is formed, and a layer of opaque paper is adhered by using the black glue layer as the adhesive layer. Through holes are provided in the vertical direction of the entire surface. Compared with existing products, the printing material is advantaged in that: the unidirectional-transparent film is applied on an LED display screen, such that a function of advertisement changeability of the LED display screen is achieved, and an advertisement effect is brought by the unidirectional-transparent film, such that good advertising and marking effects are provided; ink absorption performance of the material is good, image precision is high, and the color is bright; and the material has excellent aging resistance, ductility resistance, UV resistance, and stiff and smooth characteristics. With the material, different advertisement decorative effects are achieved, and application space is saved. Different visual effects can be provided days and nights.

Description

technical field [0001] The invention relates to a one-way see-through printing material for an LED display, relating to an advertisement display and decorative material, in particular to a one-way see-through printing material for an LED display. Background technique [0002] One-way see-through film is a flat consumable for advertising. The one-way see-through film currently on the market is mainly used to paste on automobile body glass, glass curtain wall, shopping mall glass window, etc. to display advertising decoration effects. [0003] This type of product can only be applied to print advertisements and decorations pasted on the surface of glass materials, so there is a singleness in the advertisements made of this type of material, and it cannot play the effect of advertisement decoration in dark places, and cannot be used as a one-way LED display screen. See-through printing materials, and it is impossible to change the display content through the change of the LED d...
