Description

  In particular, the present invention is used by mounting on an electronic product equipped with a liquid crystal panel, and an ink layer and an ink layer are provided to hide a circuit pattern when the liquid crystal panel is in a standby state or when the power is turned off. The present invention relates to a decorative panel in which light can be adjusted so that a visible region that is not visible looks the same color.

  In general, in an electronic product equipped with an image display device such as a mobile phone, in order to make the screen appear more beautiful, it is not necessary to expose an invisible region (for example, a circuit pattern of the substrate) on the periphery of the substrate of the display device. An ink layer for hiding the portion) is provided.

  However, when the electronic product is in a standby state or the power is turned off, that is, when the backlight is not emitting light, the visible layer surrounded by the ink layer and the ink layer becomes visible by irradiation with natural light. Due to the difference, the user can easily distinguish between the image visible area and the image invisible area, so that the user feels that the screen is not beautiful.

  In order to solve the above-described drawbacks, a structure has been devised in which an ink layer is provided after a mirror film is provided on the bottom surface of an upper layer member of a display device in an electronic product. According to this structure, since most of the external light can be reflected by the mirror film, the contrast of the display screen is lowered, and the color difference between the image visible region and the ink layer is reduced in the power-off state.

  However, in the conventional structure, the mirror film not only reflects external light, but also shields light from the backlight at the same time. Therefore, a backlight capable of providing higher emission luminance is required. As a result, more power is consumed, and the improvement effect by the mirror film is not so good.

  Accordingly, the present invention has been devised and an object of the present invention is to provide a decorative panel capable of adjusting light, in which the colors of the ink layer and the visible region surrounded by the ink layer look the same.

  The upper conductive layer (12) is provided above the lower conductive layer (11) and on the lower surface of the polarizing plate (20), and an electrode (on the periphery of the lower surface of the upper conductive layer (12)). 120). In this embodiment, the upper conductive layer (12) may be an ITO conductive film, but may be another member.

  The space layer (13) includes a plurality of dot spacers (130) and a double-sided tape (131) located at the periphery and surrounding the plurality of dot spacers (130), and the upper conductive layer (12). And the lower conductive layer (11), the double-sided tape (131) is adhered to the upper conductive layer (12) and the lower conductive layer (11).

  Further, the touch panel includes a flexible circuit board (14), and one end of the flexible circuit board (14) is provided between the upper conductive layer (12) and the lower conductive layer (11). The electrode (120) in 12) and the electrode (110) in the lower conductive layer (11) are electrically connected.

  The decorative panel according to the present invention is used by being installed in front of the display device, and thereby, an image invisible region such as a circuit pattern on the periphery of the display device can be hidden by the ink layer (31), so that the appearance is improved. When the support member (10) is a touch panel, the electrode (120) in the upper conductive layer (12) and the electrode (110) in the lower conductive layer (11) can be simultaneously formed on the ink layer. It can be hidden by (31).

  In addition, when the backlight in the display device is not emitting light, the polarizing plate (20) polarizes external light, so that the region without the ink layer (31) of the decorative member (30) has a natural light environment. The same color as the ink layer (31). For example, when the ink layer (31) is black, the region surrounded by the ink layer (31) in the decorative member (30) also appears black. That is, since the ink layer (31) and the region without the ink layer (31) have the same color, the user cannot distinguish between the visible region and the invisible region in a natural light environment.

  Since the present invention has the above-described configuration, in a natural light environment, the region of the decorative member where the ink layer is not provided appears to be the same color as the ink layer. Therefore, when the display device equipped with the present invention is in a standby state or turned off, the screen viewed by the user cannot be distinguished from the image visible region and the invisible region in a natural light environment. Because it is the same color, the screen feels more beautiful.
