Problems solved by technology

However, sunlight is reflected by the surface of the display, and if it enters the eyes of passengers, it is difficult to see the screen, so in order to improve the visibility of the screen, it is necessary to reduce the surface reflectance

Embodiment approach 1

[0101] figure 1 It is a sectional view showing the structure of the optical functional resin panel of Embodiment 1. figure 1 in, for with figure 2 The same symbols are used for the same constituent elements, and their descriptions are omitted.

[0102] figure 1 Among them, the optical functional resin panel is configured to include a base film 20 on which a hard coat layer 21 is formed on the surface of an injection molded resin 17 , and a reflectance control layer 11 is formed on the surface of the hard coat layer 21 . The reflectance control layer 11 is composed of a middle refractive index layer 16 , a high refractive index layer 13 , and a low refractive index layer 12 in this order from the hard coat layer 21 side toward the surface side.

[0103] According to the optical functional resin panel of Embodiment 1, even when the resin molded product has a three-dimensional shape, it has high surface hardness, and can have a uniform low reflectance surface function corre...

Embodiment approach 2

[0141] Figure 9 It is a sectional view showing the structure of the optical functional resin panel of Embodiment 2. Figure 9 in, for with figure 1 Components that are the same as those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted.

[0142] exist Figure 9 In the insert molding product 41, there are a base film 20 for insert molding and a first hard coat layer 21 formed on the surface thereof. In addition, on the surface of the first hard coat layer 21, the reflectance control layer 11 is formed after the applied second hard coat layer 25 made of a hard coat material is formed.

[0143] The hard coat material of the second hard coat layer 25 formed by coating does not need to be extensible because it is formed by coating. Therefore, the hard coat material of the second hard coat layer 25 can be set higher than the surface hardness of the ultraviolet curable resin constituting the first hard coat layer 21 as compared with t...

Abstract

The invention relates to an optical functional resin panel and a method for manufacturing the same. An optical functional resin panel includes an injection molding resin, a base film on the surface of the injection molding resin, an ultraviolet curable hard coat layer provided on a surface of the base film, and a reflectance control layer provided on a surface of the hard coat layer, in which the reflectance control layer has a thickness variation of 10% or less, and the base film, the hard coat layer, and the reflectance control layer have a surface hardness increasing in this order.

Description

technical field [0001] The present invention relates to an optically functional resin panel having high surface hardness and uniform and excellent anti-reflection performance in a transparent resin protective cover disposed on the surface of a vehicle-mounted display, and a method for manufacturing the same. Background technique [0002] Using liquid crystal displays, it is possible to install devices that display information such as navigation, audio, entertainment, and speedometers in the car. Along with the development of in-vehicle displays, the number and design of mounted displays have been diversified. On the other hand, from the design requirements, I don't like to install a sunshade that prevents sunlight from entering the display, but requires that the display be arranged in the cockpit at such an angle that the sunlight directly enters the surface of the display from the window of the car. upper position. However, since sunlight is reflected by the surface of th...
