Problems solved by technology

However, it can be understood that the shielding layer often needs a certain thickness to achieve the shielding effect, but the height formed by the shielding layer being too thick will lead to the inability of the sensing electrode layer to climb up the shielding layer smoothly when extending to the shielding layer. form a circuit breaker

Embodiment Construction

[0015] The repeated symbols or signs may be used in the following different embodiments, and these repetitions are only for the purpose of simply and clearly describing the present invention, and do not represent any relationship between the different embodiments and / or structures discussed. Furthermore, when it is mentioned that a first material layer is located on or above a second material layer, it includes the situation that the first material layer is in direct contact with the second material layer or is separated by one or more other material layers. In the drawings, the shape or thickness of the embodiment may be exaggerated to simplify or highlight its features. In addition, components not shown or described in the figure can be in any form known to those skilled in the art.

[0016] See figure 1 , shows a cross-sectional view of the touch panel according to the first embodiment of the present invention. Such as figure 1 As shown, the touch panel 100 is defined wi...

Abstract

The invention provides a touch panel. The touch panel comprises a first shielding layer arranged on one region on the surface of a substrate, a second shielding layer arranged on the first shielding layer and provided with a communication hole, an induction electrode layer arranged on the other region on the surface of the substrate, further arranged between the first shielding layer and the second shielding layer in an extending mode and partially exposed through the communication hole, and a conductive filling layer arranged in the communication hole and electrically connected with the induction electrode layer. The invention further provides a manufacturing method of the touch panel. Thus, the short circuit condition is prevented from occurring when the induction electrode layer on the touch panel extends to the shielding layers and the yield of the touch panel is effectively increased.

Description

technical field [0001] The invention relates to touch technology, in particular to a touch panel and a manufacturing method thereof. Background technique [0002] With the rapid advancement of technology, the applications of consumer electronic products are becoming more and more diverse. For example, many portable electronic products (such as personal digital assistants (PDA) or mobile phones) have widely used touch Panel (touch panel). [0003] The shielding layer of the touch panel has the function of shielding the surrounding components, so that the user will not be aware of the existence of the surrounding components. In addition, the shielding layer may be designed in different colors depending on the design of the actually matched electronic product. However, it can be understood that the shielding layer often needs a certain thickness to achieve the shielding effect, but the height formed by the shielding layer being too thick will cause the sensing electrode layer...
