Description

Pure white film for LED display and the manufacturing method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a white film for LED displays, and more particularly, to displays of commercial home appliances and other electronic products (refrigerators, kimchi refrigerators, air cleaners, water purifiers, air conditioners, and the like). The present invention relates to a white film for an LED display and a method of manufacturing the same, wherein the color of the film to be realized is a pure white color (white).

In general, the film for the LED display is generally designed to white the area where the LED is projected on a black background. Looking at the manufacturing process of the film for LED display using such a black (Black) printing as follows.

That is, the conventional manufacturing process of the film for LED display is a material (for example, dark ink such as black ink) that can shield the light on the base portion except for the character portion to be expressed by the fabric of the fabric to work Print with Accordingly, when the LED is turned on, the printed background portion is shielded by the LED light, and the unprinted portion is transmitted through the LED light to express the corresponding character.

In other words, the film for the LED display should be able to completely shield the light and the text portion is clearly expressed except the base portion. To this end, a color (for example, black, silver, gray) ink capable of shielding light is commonly used in the base portion of the film for LED display.

1 is a diagram showing an example of a conventional general LED display film.

As shown, the film for LED display is intended to be represented by the letter "silence" through the light emission of the LED.

To this end, the conventional film for LED display is a non-printing treatment of the letter portion 20, "silent", and prints the remaining base portion 10 with a material that can be shielded light. Accordingly, when the LED light is emitted, the base portion 10 may be shielded from light, and the light may be transmitted through the character portion 20 so that the letter “silence” may be expressed.

Recently, attention has been focused on external design as well as the performance of the product, and in response to this interest, a film for LED display having a white surface on the basis of the spotlight in the market.

2 is a view showing a manufacturing process of a conventional LED display film.

As shown in the drawing, first, a film fabric for LED display (for example, PC, PVC, PET) and a shielding ink (for example, black, silver, gray, and white ink) of LED light are prepared (S10). .

After that, the trial is made larger than the size of the character to be expressed using the fabric (S20). In addition, the trial is manufactured in the character size to be expressed using the fabric (S30).

Subsequently, the fabric is printed in a larger size than the character size, and the area except for the character area is printed with ink for shielding LED light (black, silver, gray) (S40). In addition, the printed area is printed in white ink on an area except for the letter area in a trial manufactured in letter size (S50). Thereafter, the film for LED display is completed through the processing operation (S60).

Figure 3a) is a view showing a state printed using a trial 35 made larger than the character to be expressed on the fabric produced by the step S20 of FIG. In the drawing, the substrate surface except for the trial 35 is printed with a material capable of shielding light (for example, black, silver, and gray inks), and the trial 35 is printed without printing.

FIG. 3 b is a view showing a state of printing using the trial 45 manufactured in the character size to be expressed on the fabric produced by the step S30 of FIG. In the drawing, the base surface except for the trial 45 is printed with white ink, and the trial 45 is unprinted.

3 c shows the printing state using two trials 35 and 45 as shown in FIG. 3 a) and FIG. 3 b). As shown, the characters 55 printed on the film 50 are demarcated by a double print job of different sizes for the same characters to be represented.

4 is an enlarged view of a printing state of a film for LED display manufactured through the fixing of FIGS. 2 and 3.

As shown, looking at the printing state of each area of the LED display film 50 is as follows. That is, the base surface 51 of the LED display film 50 is printed with the LED light shielding ink (black, silver, gray) printed by the step S40 of FIG. 2 and the white ink printed by the step S50. . Further, the character area 52 of the size to be expressed is an unprinted area where no printing is performed by the steps S40 and S50. In the region 53 except for the character size region 52 among the trial regions manufactured larger than the character size, white ink printed by the step S50 is printed.

This conventional LED display film has a problem that it is difficult to match the exact point (Point) for the two trials because it uses two trials. Accordingly, there is a problem in that the character to be expressed is not clear due to the white print area 53, and border lines appear.

In addition, the conventional LED display film has a disadvantage that the base surface 51 is printed with a white (close to gray) or black color rather than a pure white as the base 51 is printed with a shielding ink and white ink of the LED emitting light. .
