The vivid and direct touch mode has enabled many R&D companies to apply touch panels to portable consumer electronics products such as mobile phones, MP3 players, personal digital assistants (PDAs), and digital cameras. The touch panel can be made of different types of resistive touch panels, such as resistive, capacitive, infrared, and ultrasonic, according to its technology. The main components are: upper and lower conductive I, and upper and lower conductive. Between the layers, the spacer layer and the protective layer, the upper and lower conductive layers are respectively arranged with conductive lines on the peripheral sides in the horizontal and vertical directions, and a good road is formed to form a line area, and the line area is surrounded by The inner area is the Touch & touch layer of the touch field, and the protective layer is located above the upper and lower power layers, as a touch for providing the hand touch $ ^ ... Ding A touches the rainbow. Further, the bottom surface of the protective layer corresponds to the position of the wiring region, and an ink layer is usually formed, thereby shielding the wiring region and making the overall surface beautiful. y However, the ink layer σ soil layer and the touch area of the touch panel are in the standby or off state of the attached electric battery, that is, the backlight module of the LCD screen is not sent to the M356139 light. Under the condition of the touch area, the surface of the touch area can still be seen by the external light projection. As the range of the touch area and the ink layer range cannot be integrated in the appearance, it can be easily made from the color difference. The difference is that the contrast between the product's shutdown (or standby) and the two appearances of the screen in use is not significant enough. Therefore, some manufacturers first form a mirror coating on the bottom of the protective layer, and then set the ink layer to reflect most of the external light by the mirror mineral film, so that the contrast between the touch area and the ink layer in the standby state is achieved. Reduced, however, the lack of this method is that the mirror coating is not only reflecting the external light, but also affecting the penetration of the light of the backlight module, so that the liquid crystal glory of the electronic product is reduced, resulting in the necessity of enhancing the backlight module of the rear end of the screen. Luminous brightness increases the power consumption of electronic products; and the improvement of mirror coating is limited, and the visual contrast provided by the overall interface still has some shortcomings. [New Content] • In view of this, the main purpose of this creation is to provide a touch panel with light adjustment function, which is applied to the touch panel under standby or off state when applied to an electronic product with a liquid crystal screen. The color between the ink layers 'for the peripheral shielding lines is similar. / The technical means used for the above purposes, the touch panel of the ^7 °Haiguang light adjustment function comprises: - a lower conductive layer, a conductive line is formed around the upper surface thereof. - a gap layer, a system On the lower conductive layer; the upper conductive layer is disposed on the gap layer, and the upper conductive surface is formed on the lower surface of the electrical layer; 4 M356139 a polarizing plate is disposed on the upper conductive layer The base-decorative layer is disposed on the polarizing plate, and an ink layer is formed on the lower surface of the t-decorative layer to correspond to the conductive line shielding the upper and lower conductive layers; and an anti-reflection layer is disposed on the decorative layer. on.
