New Description: [New Technology Field] This creation is about a touch panel, especially a touch panel with a strong light blocking effect. [Prior Art] At present, the touch panel with a high market share has different resistances and capacitance types according to the working principle. Among them, the resistive touch panel includes four-wire and five-wire, six-wire or Eight-wire type; capacitive type is divided into surface capacitance type (SCT) and projected capacitance type (PCT). The touch panel of the above-mentioned touch panel is mainly composed of a substrate which is transparent and has two opposite surfaces, wherein one or more surfaces are formed with a transparent electrode layer (ITO); and the capacitive touch panel is activated. The principle is that when the finger of the human body approaches the transparent electrode layer, a capacitance is formed between the finger and the transparent electrode layer, so that the total capacitance of the transparent electrode layer changes, so when the hand Φ refers to the touch panel, the transparent electrode layer The electric valley value corresponding to the coordinate position will change, as long as the position of the coordinate changed by detecting the capacitance value of the transparent electric layer is the position touched by the finger. Referring to FIG. 7 , the touch panel 91 is generally disposed on a display panel 92. Since the substrate and the transparent electrodes of the touch panel 91 are transparent, the image displayed on the display panel 92 under the touch panel can be viewed. However, since the general display panel 92 takes into consideration the aesthetics of the displayed image, the surface is made of a smooth material, and therefore has the property of easily reflecting light. When it is located at a strong light, such as when it is sunny, the light passes through the touch panel 91. After the surface of the display panel 92 is reflected, the visibility of the image displayed on the display panel 82 is affected, so that the user cannot see the image clearly under strong light, which is inconvenient for outdoor use, so the touch panel needs to be improved. [New content] In view of the above technical defects that the existing touch panel cannot resist glare, the main purpose of the present invention is to propose a touch panel having a glare blocking effect. The main technical means for achieving the above purpose is that the touch panel having the glare blocking effect comprises: the substrate 'having two opposite surfaces, and one or more surfaces are formed with more than one transparent electrode layer; The discoloration layer is disposed on one surface of the substrate, and the light transmittance of the photochromic layer changes according to the intensity of ultraviolet light irradiation, and the ultraviolet light intensity is strong, the light transmittance is deteriorated; When the light intensity is weak, the light transmittance is improved. Since the photo-chromic layer is disposed on one surface of the substrate of the touch panel of the present invention, the touch panel is disposed on the display panel, and the photochromic layer is exposed to light when exposed to strong light. The strong ultraviolet light reduces the transmittance, thereby greatly blocking the light penetration and reflection' greatly reducing the influence of the strong light reflection, so that the display image of the display panel is still clearly visible. [Embodiment] Please refer to FIG. 1 for the basic structure of the present invention.

The opposite surface of the X-axis sensing region 16 forms an ink layer 21 corresponding to the wiring region 71, and a cured film 22 is formed to completely cover the ink layer 21 and the substrate 7 surface. After the touch panel of the present invention is disposed on a display panel, if the user carries it for internal use, the intensity of the ultraviolet light contained in the indoor light is insufficient to make the photochromic layer 20 bleed, thereby making the photochromic Layer 2 is still transparent, so it does not affect the display image of the panel. When it is exposed to strong light and is exposed to strong light, it will look like a $6 towel. The photochromic layer 2G is discolored by the ultraviolet light in the strong light. At this time, the photochromic layer 2 〇 blocks most of the strong light from refracting, and refracts the glare after entering the display panel 92. After the upper reflection, the photochromic layer 20 blocks most of the 'only a small part of the light from the photochromic layer' can effectively block the glare from the outside, as for the display panel 92. The light is blocked only when the photochromic layer 2G is refracted, so that the light emitted by the display panel 92 is higher than the light from the outside with respect to the light that is blocked twice from the outside, so that the light is displayed. The image displayed by the panel is still clearly visibleIn summary, the photochromic layer of this creation can be changed according to the light intensity. 7 ΙΌΌ H 14 (4) External light can be maintained through the influence of the Japanese display: *, when the external light is strong, the light from the outside is greatly blocked. The reflection makes the light emitted by the display panel stronger than the reflection of the external light, so that the user can clearly see the display image of the display panel and block the glare.
