Problems solved by technology
[0004] However, the manufacturing process of the touch panel includes the process of anti-ultraviolet light testing, and the touch panel may be exposed to sunlight for a long time during use. Due to the influence of ultraviolet light (mainly in the wavelength range of 280nm to 420nm), the shielding layer will be damaged. Aging causes opacity to decrease, which seriously damages the appearance of the touch panel; therefore, the industry needs a touch panel with anti-ultraviolet light ability and prevents the opacity of the non-visible area from decreasing.

Abstract
The present invention provides a touch panel, which defines a visible area and a non-visible area for distinguishing the visible area, and defines the side close to the user as the lower side, and the side far away from the user as the upper side. The feature is that the touch panel includes: a substrate having an upper surface and a lower surface; a shielding layer located on the upper surface of the substrate, wherein the shielding layer defines the non-visible area; a sensing electrode layer , located on the upper side of the substrate and at least in the visible area; a signal wiring layer, the signal wiring layer is located on the upper side of the shielding layer, and electrically connected to the sensing electrode layer, wherein the signal wiring layer includes a plurality of metal leads; and an anti-aging layer located on the lower side of the shielding layer. Thereby, the touch panel of the present invention can increase the ability to resist ultraviolet light and prolong the service life of the touch panel.
Description
technical field [0001] The present invention relates to a touch technology, and in particular to a touch panel. Background technique [0002] With the evolution of touch technology (Touch control), touch panels have been widely used in various consumer electronic devices, such as: smart phones, tablet computers, cameras, e-books, MP3 players and other portable electronic devices. products, or display screens applied to operator control equipment. [0003] A touch panel is usually defined with a non-visible area and a visible area corresponding to the non-visible area. Defined by the placement of a masking layer, the material of which is usually ink or photoresist. [0004] However, the manufacturing process of the touch panel includes the process of anti-ultraviolet light testing, and the touch panel may be exposed to sunlight for a long time during use. Due to the influence of ultraviolet light (mainly in the wavelength range of 280nm to 420nm), the shielding layer will b...
