Description of the Invention: [Technical Field] The present invention relates to an anti-reflection thin-shaped touch panel, and more particularly to a touch panel having high anti-reflection effect and thinning. [Prior Art] A flat panel display having a touch function has a wide variety of methods and structures. The early touch panels were independently produced, and were combined with the LCD panel of the size to be completed. Therefore, if a flat panel display with touch function is to be manufactured, the most direct method is to apply a layer of adhesive layer to a touch panel. To adhere to the front surface of the front panel of the liquid crystal display panel. In the development process of this touch-type flat panel display, there is a technical problem that the visibility is too low under the illumination of sunlight or strong light source, that is, the flat display itself is visible due to the intensity of the ambient light. The difference in quality and quality, so if the liquid crystal display with touch panel is directly exposed to sunlight or strong light source, it will produce severe reflections, resulting in an overall reflectivity of 25%, so the touch-type liquid crystal flat panel display is strong Under the illumination, it is not clear from the light-emitting surface of the liquid crystal display. Recently, the technology for reducing the touch-sensitive flat display ϋ reflectivity to improve the visibility has been improved. The improved touch panel structure is proposed, as shown in the second figure. The basic structure of the general touch panel (5〇) is on a glass substrate... The next layer of conductive film (layer...)/mesh layer is formed in series (..., -... two electricity - electricity: 4 200839588 (5 6 ), an upper conductive electrode layer (57) and a unidirectional polymer material layer (59), and the upper surface of the unidirectional polymer material layer is sputtered with an upper conductive film (58); wherein the surface of the unidirectional polymer material layer (59) is further provided with a polarizing # (6〇) in the upper layer of the anti-reflective polymer material plate (61), and on the glass substrate (5ι): The 1/4λ phase difference plate (6 2) is attached to the end, so that the principle of polarized light plus the principle of a circular polarizer can be used to make the touch panel (5 〇)

Therefore, there are still some shortcomings in the structural design of the touch panel, because the anti-reflective polymer material plate, the polarizing plate, the 1/4" mesh difference plate, and the unidirectional polymer material layer all ask the knife material layer. Not only the overall manufacturing cost is expensive, but also seriously affects the brightness of the display, but the best display quality is not achieved. Because of the addition of these polymer layers, the overall thickness increase yield is reduced. And the 1/4 it differential plate is extremely soft. Polymer materials are not only difficult to add and can not be cleaned. For this reason, the main V of the present invention, k, is provided with an anti-reflection thin touch panel, so that the touch panel is strong and strong. Under the premise of high visibility under the source, the optimal thinning structure design is achieved. The main technical means used by y moxibustion for the purpose of 4 people is to make the anti-reflective thin touch panel mainly integrate eight. The A ° 卩 高分子 polymer layer is a single high knive material polarizing material layer, so that Α 7 具有 recorded polarized and high anti-reflective optical special 5 200839588, the polymer polarizing material layer is formed in a high anti-reflection Optical layer of molecular material a lower end surface, and further bonded to the molecular material layer with a 1/4 λ phase difference, and an upper conductive electrode layer formed on the upper conductive film polymer material layer to form a complete The V private thin plate on the touch panel is combined with the lower conductive plate to form a touch panel. The present invention is effective in simplifying the entire process of the touch panel, reducing manufacturing cost and improving yield.

[Embodiment] Referring first to the first embodiment, it is a schematic structural view of a touch panel (i 〇) according to a preferred embodiment of the present invention, which includes: ^ upper V electric board (2 〇), tied to An anti-reflective polymer material optical layer (2 1 ) is further formed with a layer of anti-reflective polymer polarizing material (2 2 ) and an upper conductive film (23) having a phase difference of 1 Μλ, and The conductive film is further formed with an upper conductive electrode (24); wherein the high anti-reflective polymer polarizing material I (2 2 ) has both polarization and high anti-reflection, and the characteristics of the drop-off are The material layer of the polymer material optical layer (2 1 ) may include a high anti-reflection coating, triacetyl cellulose, polyethyl alcohol, cellulose triacetate film, polyethylene terephthalate, etc.; The conductive plate (3 〇) is bonded to the upper conductive layer 200839588 sheet (2 〇) by an adhesive layer (40), wherein the lower conductive plate (3 〇) is formed on a substrate (31) with a transparent conductive layer. a thin film (32), and a transparent conductive electrode layer (3 3 ) and a dot layer (3 4) are formed thereon, and then An insulating layer (35) is formed on the upper conductive electrode layer (33), and the insulating layer (35) is adhered to the adhesive layer (40); wherein the substrate (31) is a glass substrate. Also, as shown in the first figure, the lower end surface of the base φ plate (3 1 ) of the lower conductive plate (3 )) is adhered to a layer of 1 Μ phase difference plate (3 6 ), since 1/4 λ is simply added. The phase difference plate is likely to be scratched or scrapped after being wiped by alcohol, so it is hardened on the phase difference plate to form a high hardness 1 / 4 λ phase difference plate. It can be seen from the above description that the present invention integrates two layers of polymer material into a single optical layer (thickness of about 13 〇-138 um), and the optical layer has both polarized light and high anti-reflection optical characteristics, compared with the set anti-reflection. Reflective plastic film and polarizer (the thickness of the two layers is about 300-400um), the touch panel can be said to greatly reduce the overall thickness.
