However, since the shielding layer is only arranged on the cover plate at a position corresponding to the peripheral circuit area of the capacitive touch panel, there is a gap between the shielding layer and the surface of the cover plate. When it is attached to the capacitive touch panel, air bubbles are likely to be generated at the step difference, which affects the appearance of the capacitive touch screen
In addition, since the shielding layer is coated with black resin, it is easy to cause a partial area on the surface of the cover plate corresponding to the peripheral circuit area not to be covered by black resin due to process or operation, resulting in light leakage, or the The lead of the capacitive touch panel affects the appearance
At the same time, when bonding the cover plate to the capacitive touch panel, it is easy for the glue used for bonding to overflow from the outer edge of the shielding layer, making it difficult to clean

The invention relates to the display technical field, in particular to a shielding structure, which at least includes a first shielding layer, a second shielding layer, and a third shielding layer, wherein the first shielding layer and the third shielding layer are arranged at an interval to form a first accommodating space; the second shielding layer is arranged on the first shielding layer and partially covers the first shielding layer; at least one side of the first shielding layer, which is far away from the third shielding layer, is not covered by the second shielding layer, and forms a first step with the second shielding layer. Besides, the invention further provides a capacitive touch panel using the shielding structure, and a preparation method thereof.
Description
technical field [0001] The present invention relates to the technical field of touch display, in particular to a shielding structure, a capacitive touch panel using the shielding structure and a manufacturing method thereof. Background technique [0002] Touch panels are classified into resistive touch panels, capacitive touch panels, infrared touch panels and acoustic wave touch panels according to their different touch principles. [0003] Resistive, infrared, and acoustic wave touch panels are not suitable for use as an operation interface of a handheld mobile terminal due to defects caused by their working principles. Capacitive touch panels are widely used in handheld mobile terminals due to their good touch sensitivity, long service life, and less interference from external signals. [0004] Capacitive touch panels are further divided into surface capacitive touch panels and projected capacitive touch panels. Since the surface capacitive touch panel can only realize ...
