Field of the Invention The present invention relates to a touch panel, which is applied between a screen display of a range of a touch area in a standby state and an ink layer of a shielded line area when applied to a liquid crystal electronic product. The color is close to the same. [Prior Art] More and more electronic products are input using the touch & interface, and the touch panel is mounted on the upper end of the LCD screen, which can be directly clicked to provide an intuitive and vivid human interface. Due to the application of touch panels, portable consumer tweezers in mobile phones, MP3 players, personal digital assistants (PDAs), etc., which are widely used in the market, will gradually expand. Generally, the touch panel can be distinguished by a resistive type, a capacitive type, an infrared type, etc., wherein the 'resistive touch panel mainly includes an upper and a lower conductive layer and is sandwiched between the upper and lower conductive layers. a spacer layer (d〇t buckle factory) and a protective layer, the upper and lower conductive layers are respectively arranged with conductive lines on the peripheral sides in the horizontal and vertical directions, thereby forming a line area, and the inner area surrounded by the line area is For the touch area of the touch panel, the protective layer is located above the upper and lower conductive layers as a touch end for providing a finger or a stylus to operate. Moreover, in practical applications, the touch panel usually forms an ink layer at a position corresponding to the line region on the bottom surface of the protective layer to shield the circuit region for the aesthetic appearance of the entire surface. However, when the ink layer and the touch area of the touch panel are in a standby or off state, that is, when the backlight module is not illuminated, the surface of the touch panel 3.201025092 can still be projected by external light. It is clearly seen that since the range of the touch area and the range of the ink layer cannot be integrated in appearance, it is easy to make a distinction from the color difference, which will make the contrast effect of the product in the two states of shutdown and use two states insufficient. In order to improve the '遂有薇商, the surface of the protective layer that provides the touch is first formed - the mirror clock film' and then the ink layer is set, and the mirror coating is used to reflect most of the external light, so that the touch area and the ink layer are in standby state.
