As shown in fig. 5 (2), a background layer 102 is formed by screen printing in an area of the base material 101 other than the color mark layer 103.

In one embodiment, the background layer 102 includes opaque light-shielding layers formed outside the color icon A, B, C, D, and the light-shielding layers do not allow light to pass through, and can prevent the area outside the color icon A, B, C, D from being illuminated by the light-emitting member, so as to affect the display effect of the color icon, and make the color icon A, B, C, D more obvious under illumination. In another embodiment, the background layer 102 may be semi-transparent and the transparency of the background layer 102 may be less than the transparency of the colored icon A, B, C, D.

In some embodiments, the colored film panel 11 includes a diffuser layer 104 formed over the colored icons A, B, C, D to make the light emitted from the colored icons A, B, C, D more uniform. The light-diffusing layer 104 is formed on the side of the color icon A, B, C, D opposite the substrate 101. In one embodiment, the light diffusion layer 104 is translucent to prevent light leakage, and can block components, such as light emitting members, located behind the color film panel 11 in a display screen of a home appliance using the color film panel 11, to prevent the components from being seen by a user from the color film panel 11, thereby improving aesthetic appearance and making the color icon A, B, C, D clear. As shown in fig. 5 (3), a light diffusion layer 104 is printed on the surface of the color mark layer 103 opposite to the base material 101. In one embodiment, the diffuser layer 104 may be screen printed using a semi-transparent white ink. In another embodiment, the light dispersing layer 104 may be formed by printing with a material containing light dispersing particles.

Referring to fig. 7, in an embodiment, the color film panel includes a translucent bottom color layer 208 formed on a first surface of the substrate 201, and the hidden color icon is formed on a surface of the bottom color layer 208 opposite to the substrate 201, and a variety of substrates 201 can be selected. The substrate 201 may be a fully transparent substrate, and the bottom color layer 208 may be formed on the surface of the substrate 201 by screen printing using a translucent ink. In some embodiments, the color of the base color layer 208 may be the same or close to the exterior color of the home appliance using the colored film panel, for example, the same or close to the panel color of the home appliance display screen of the home appliance, to harmonize the appearance color of the home appliance. In one example, the base color layer 208 is black or silver. As shown in fig. 7 (2), a color icon A, B, C, D is formed by four-color printing on the side of the ground color layer 208 opposite to the base material 201.

As shown in fig. 7 (3), the background layer 202 is printed in the area of the background layer 208 outside the color icon A, B, C, D. The background layer 202 may make the colored icon A, B, C, D visible and may make the appearance pleasing. The background layer 202 may be formed by screen printing. The background layer 202 may be an opaque light-shielding layer. The background layer 202 is similar to the background layer 102 shown in fig. 5 and will not be described in detail here.

In another embodiment, the background layer 202 is formed between the basecoat layer 208 and the substrate 201, with the color icon A, B, C, D offset from the background layer 202. The background layer 202 is formed on the substrate 201 to leave a region where the color icon A, B, C, D is required, the background layer 208 is formed on the background layer 202 and the region left on the substrate 201, and the color icon A, B, C, D is formed on the background layer 208. The colored icon A, B, C, D does not overlap with the background layer 202.

In another embodiment, the background layer 202 is formed on the substrate 201, and the base color layer 208 and the colored icons A, B, C, D are offset from the background layer 202. The material of the base color layer 208 may be saved. The base color layer 208 and the color icon A, B, C, D are overlapped, and the color icon A, B, C, D is positioned on the side of the base color layer 208 opposite to the substrate 201, so that the base color layer 208 and the color icon A, B, C, D are not overlapped with the background layer 202 for hiding the color icon.

In another embodiment, the substrate 201 is a translucent substrate and the hidden color icon is formed on the translucent substrate. The base color layer 208 may be omitted, the color icon layer 203 may be directly formed on the surface of the substrate 201, and the background layer 202 may also be directly formed on the surface of the substrate 201. The process is simplified.

Similar to the diffusion layer 104 shown in fig. 5, in the embodiment shown in fig. 7, a translucent diffusion layer 204 may be formed by screen printing on the side of the color mark layer 103 facing away from the substrate 201, as shown in fig. 4 in fig. 7, and described in detail above.
