Description of the invention: [Technical field of the invention] A panel, in particular, a touch panel having an anti-electromagnetic interference function. [Prior Art], the electrical device is vulnerable to the influence of the high electromagnetic field environment and changes its characteristics, so it will increase the anti-electromagnetic interference, and the production of the inspection will prevent the electrical device from being affected during operation. Common high electromagnetic field environments are like hospitals or military bases. Because these rings use: frequency medical or communication equipment, it is best to add anti-electromagnetic interference to the electronic products used in this environment. —^ For the current touch-sensitive liquid crystal display, in order to maintain the normal display function, the outer casing is designed as a metal casing and grounded, and it has anti-electromagnetic interference function. However, only the outer casing is designed to be grounded metal = Asia does not have the function of essay to achieve electromagnetic interference, so at present; t people will touch: the outermost touch panel of the liquid crystal display is designed to have electromagnetic resistance, first Reduce the normal display effect of external electromagnetic interference. 6 Since the touch panel is disposed on the front end surface of the liquid crystal panel, the anti-p magnetic interference technology is added, which may not have an excessive influence on the influence image, because the light-transmitting material of the first consideration is used as a transparent electrode. I π j ΙΖ0 film, the specific structure is to plate IT 在 on a layer of polymer film, and then coated with I τ ο film bonded to the outer surface of the bottom surface of the touch panel, but because the film is a polymer material, it has long been After use, there is a problem that the touch panel bottom plate 1 is poorly occupied. Furthermore, since the ITQ film is fully attached to the touch panel of 200839361, and the touch panel is disposed on the front end surface of the liquid crystal display, It will reduce the light penetration of the entire liquid crystal display and affect the development effect. In addition, due to the ITO material characteristics, the effect against electromagnetic interference is not good. Based on the above disadvantages of poor adhesion, some people directly on the bottom of the touch panel. The bottom surface is fully coated with an ITO film to avoid the problem of the polymer film sticking to the bottom plate, but it will still affect the light penetration, which will reduce the transmittance by about 5%~10%. Refer to the attached-show, which is a chart and data list for the detection of electromagnetic interference by the liquid crystal display of the anti-electromagnetic interference touch panel as the installation-mineral ΙΤ0. It can be seen that there are 19 frequency detection results exceeding the electromagnetic Tolerance value; in addition, the most original material 44 ... effective to achieve anti-electromagnetic interference ^ fruit of the shortcomings still exist, and ^ ν ^ ^ to minimize the impact of the first tooth permeability, skin; must be below 100 pieces of resistance, ^ ^ Also, it has an anti-electromagnetic effect, so it is mixed with metal, but it will be turned on. This is the result of the above-mentioned description of the metal film of the Yuyu. The technology for a disturbance is still necessary. In view of the above, the main touch panel of the present invention makes the use of the touch #'糸 to provide an anti-electromagnetic interference with the lowest degree of influence, and can be used daily.颏 颏 将 将 将 将 将 将 将 it it it it if if if if π π π π π 政 政 政The touch panel of the main disturbance used by the slaves includes the bamboo means for the electromagnetic anticorrosion 5 200839361 and the touch panel body, which comprises a bottom plate and an upper conductive electrode layer; The film is bonded to the lower end surface of the bottom plate of the touch panel body and electrically connected to a ground source. This I month is directly woven into a metal mesh with metal wire, which has the best anti-electromagnetic effect. The line width of each metal wire is slightly smaller than that of each element panel. § It is not installed in a liquid crystal panel and will not be seen by the naked eye. Moreover, since the jade network of the i-month is mainly a mesh structure, the bottom plate of the touch panel is not completely shielded, and the transmittance of the liquid crystal panel is relatively low. Another object of the invention (4) provides an anti-electromagnetic interference touch panel that improves the light transmission rate, that is, the metal mesh is completely coated with optical glue, so that the surface of the wire is bright, and the grid is made. The space is filled with optical glue to increase penetration. Still another object of the present invention is to provide a liquid crystal display having high electromagnetic interference resistance, the liquid crystal display comprising a metal casing, a liquid crystal panel and a backlight module, wherein the liquid crystal panel, the backlight module and the touch panel They are all assembled in the metal casing, and the metal mesh of the touch panel can directly contact the metal casing, so that the metal (4) can be externally resistant to electrical interference. [Embodiment] An exploded view of a touch panel (1 〇) display (20) of the present invention is shown in the first figure. The preferred embodiment is provided in a liquid crystal containing: 6 200839361 a touch panel The body (11), 丄丄) includes a bottom plate, a lower conductive film, a lower conductive electrode layer, a spacer layer, an insulating layer, a sticky layer, and an upper layer. a conductive electrode layer and an upper conductive film; a metal mesh (1 2 ) woven from a plurality of metal wires (1 2 1 ) and bonded to the lower end surface of the bottom surface of the touch surface 11 1 to be grounded Source connection; J: Zhonglu green /, the line width of each wire is about 0.01 to ο·ι_' and the distance between two adjacent wires is from 细1_ to 5 颜 from the thin to thick line; The preferred line pitch range of this embodiment is 〇" with 〇μ·, and the angle of the metal wires interlaced is preferably 45 degrees and 135 degrees. Further, the material of the metal wire is steel. Moreover, referring to the second figure, the metal mesh (12) is conveniently attached to the touch panel body (11), and the optical adhesive (14) is coated on the upper end surface to seal the plurality of metal wires (121). ) and bonded to the bottom plate; then a protective film (13) is attached to the lower end surface. Since the metal surface of the metal mesh (1 2 ) is a matte surface, the effect of the surface of the 7-piece copper mesh king is coated by coating the optical glue (丄4), and the space of each grid is filled to enhance the penetration of the light source. force. X, the protective film can be glass, PET, PAR, PEN, PMMA, ARTON, PES, ZEONOR, TAC or PC, etc. to avoid oxidation of the metal mesh and to protect it from external forces. As shown in the figure, the touch panel (10) is assembled to a liquid crystal display (2), and the liquid crystal display (2) includes a metal casing (2 1 ). (2丄) π is provided with a liquid crystal panel (2 2 ) and a backlight module; wherein the metal casing (2 丄) is connected to a ground source, and the touch panel (10) is assembled to the gold 7 200839361 The outer casing (2 1 ) can be directly connected to the grounding end through the metal casing (2丄). The two ends of the wire (121) of the metal_(12) extend beyond the edge of the stomach of the touch panel body (1 1 ). And the excess is not covered by the optical adhesive (14) and the protective film (13); so, as shown in the third figure: when the assembly is completed, the metal i 2 is protruded from the wire. Relying on the inner edge of the metal casing (2 1 ). It can be seen from the above description that the touch panel of the present invention mainly combines a metal mesh to the bottom plate of the touch panel. Since the metal mesh is made of a metal wire, it can effectively sense high frequency signals and effectively reduce electromagnetic interference. At the same time, as shown in Annex II, when the liquid crystal display of the present invention performs electromagnetic interference detection, the frequency-free point exceeds the tolerance value, and the line width of each wire of the metal mesh is not visible to the human eye, and the mesh structure The bottom plate of the touch panel body is not fully covered. . The coating of the yoghurt is relatively low on the light transmittance of the liquid crystal display.
