Description of the Invention: [Technical Field] The present invention relates to a touch panel, which is applied to a liquid crystal electronic product, between a screen display of a touch area range in a standby state and an ink layer of a shielded line area. The colors are close together. [Prior Art] Nowadays, more and more electronic products are input using a touch interface, and the interface touch panel is mounted on the upper end of the LCD screen, which can directly select materials on the surface to provide an intuitive and vivid human-machine interface. Because of the expected application of touch panels, portable consumer electronics products such as mobile phones, MP3 players, and personal digital assistants (PDAs) with a large consumer market will gradually expand. The touch panel can be distinguished by a resistive or capacitive 'infrared type' according to its sensing method. The towel and resistive touch panel mainly comprise upper and lower conductive layers and are sandwiched between the upper and lower conductive layers. The spacer layer and a protective layer 'up and down guide thunder @八? · 分 · Conductive layer knives are arranged in the direction of the longitudinal axis, the conductive lines _, γ & 仗, 仗 to form a line area, the inner area surrounded by the line area is the touch surface The touch area 'protective layer is located above the upper and lower conductive layers, as the touch end of the lifting: Feng ★ 々 t, the sum or the stylus. In addition, when the touch panel is used in practical applications, the sling is formed at the position corresponding to the line area on the bottom surface of the protective layer to form oil tightness rn ’·-β, which is used to shield the line area for the overall picture. However, when the ink layer and the touch area of the touch surface are in the standby or off state of the electronic product, that is, in the case where b1 is not illuminated in the first group, the range of the touch 1375903 region is The face can still be clearly seen by the external light projection. Since the range of the touch area and the ink layer range cannot be integrated in appearance, it is easy to make a difference in color difference, which will make the product shut down and use two states. The contrast effect on the screen is not significant enough. In order to improve, some manufacturers first form a mirror coating on the bottom surface of the protective layer that provides the touch, then set the ink layer, and use the mirror coating to reflect most of the external light, so that the touch area and the ink layer are in standby state.

The illuminating shell size accelerates the power consumption of electronic products; and the degree of improvement of the mirror coating is limited. The overall interface provides insufficient visual rendering effects. SUMMARY OF THE INVENTION The main purpose of the present invention is to provide a touch panel that can make the touch area range and the ink layer range melt in appearance, so that the product is not turned on and the use form g τ is presented. The contrast effect is remarkable. : Including: the technical means used to achieve the above purpose, the touch panel is wrapped with a conductive layer and a conductive layer is formed into a conductive line; a conductive line is formed on the periphery of the upper surface; and is disposed above and below the lower conductive layer a peripheral gap layer is disposed between the lower conductive layer and the upper conductive layer, and is disposed on the upper conductive layer; and 4 1375903 a decorative layer is disposed on the polarizing plate, and the lower surface of the decorative layer The peripheral layer forms an ink layer corresponding to the position of the conductive lines of the upper and lower conductive layers. When the backlight of the liquid crystal screen attached to the δ and S' touch panels of the polarizing plate is turned off, when the external light is projected on the touch panel, the color of the touch area is consistent with the color of the surrounding ink layer. The overall integration of the appearance will make the electronic products have a significant contrast effect when they are not turned on and used. [Embodiment] Referring to the first and second figures, a schematic cross-sectional view and a perspective exploded view of a preferred embodiment of the touch panel of the present invention include a conductive layer (10) and an upper conductive layer ( 20), a gap layer (30), a polarizing plate (40) and a decorative layer (50) » the lower conductive layer (10) is formed with a lower conductive line (1 1) on the upper surface of the upper conductive layer (10). The lower conductive layer (10) is Indium Tin Oxide Conductive Glass, but is not limited to indium tin oxide conductive glass. For example, as shown in the third figure, the lower conductive layer (10) The substrate (10A) and an indium tin oxide conductive film (10B) disposed on the substrate (10A) by an optical adhesive (10A) may be used. The substrate (10A) may be a plastic or glass substrate, but The two are limited. The upper conductive layer (20) is disposed above the lower conductive layer (1〇) and the upper conductive layer (21) is also formed around the lower surface, and the upper conductive layer (20) may be an indium tin oxide conductive film. The gap layer (30) is disposed between the lower conductive layer (10) and the upper conductive layer (20). The gap layer (30) includes a plurality of spacers (31) and 5 1375903 The double-sided adhesive (32) surrounding the gap layer (30) and surrounding the gaps (31) adheres the upper conductive layer (2〇) and the lower conductive layer (1〇). The polarizing plate (40) is disposed on the upper conductive layer (2 turns). In this embodiment, the optical adhesive (100) is used to adhere the two together. The decorative layer (50) is disposed on the polarizing plate (4〇), and an ink layer (51) is formed on the lower surface of the decorative layer (5〇) to correspondingly shield the upper and lower conductive layers (20) (10). The conductive circuit (21) (1)), in the embodiment, the surface of the decorative layer (5〇曰) can be further processed by an anti-reflection treatment to form an anti-reflection surface to reduce the reflection of external light, and the anti-reflection surface can be It is an anti-reflective coating. The invention may further comprise a flexible circuit board (6〇) connected at one end to the upper and lower conductive layers (2) (10) and to the conductive lines (21) of the upper and lower conductive layers (20) (10) ( 11) Connect. The invention is characterized in that a polarizing plate (40) is added above the upper conductive layer (2) so that the color of the touch area under the backlight is closed to match the color of the ink layer (51), and the ink layer (51) is used. For example, in the case of black, the polarizing plate (4(1) takes care of the outside world; the light makes the touch panel of the touch panel appear black from the appearance, and the color of the surrounding ink layer (5,)) Approaching the same, "the bright enamel surface in the state of backlight operation produces a significant contrast visual effect. In summary, the present invention mainly utilizes the addition of a polarizing plate in the touch panel crucible to make the touch panel known to the electronic product. (such as mobile phone) after the LCD screen 'can be turned off or standby (that is, when the backlight is off), let the touch, the surface of the ink and the border of the ink mask graphic color into one, increase the mouth of the electronic product The switch is written to prepare _ μμ 4 Tian J-® day contrast effect, making it more attractive to consume 6 1375903 force in appearance.
