Embodiment Construction
[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.
[0033] In the prior art, the metal bridge generally adopts a molybdenum-aluminum-molybdenum structure, wherein the aluminum acts as a conductive layer in the middle layer, and the molybdenum is divided into upper and lower layers to reduce contact resistance and protect the aluminum layer. Among them, the thickness of molybdenum-aluminum-molybdenum is generally 30 nanometers (nm)-250 nanometers-20 nanometers. Here, since the thickness of aluminum reaches 250 nanometers, its optic...

Abstract
The invention discloses a touch screen assembly, a preparation method of the touch screen assembly and a touch device. The touch screen assembly comprises a first protection layer, a conductive layerand a second protection layer which are sequentially stacked from bottom to top. Wherein the upper surface of the conductive layer is provided with a rough structure; wherein the upper surface of theconductive layer is in contact with the second protective layer, the rough structure comprises a plurality of first grooves which are regularly arranged, and the rough structure is used for enabling incident light to generate diffuse reflection and / or scattering when the incident light irradiates the conductive layer through the second protective layer. Therefore, the whitening phenomenon is reduced, and the transmittance and the display quality are improved.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a touch screen component, a method for preparing the touch screen component, and a touch device. Background technique [0002] In recent years, the development of touch display technology has been advancing by leaps and bounds, and users can directly operate on the touch display, so it has received more and more attention and applications. [0003] In the prior art, touch displays are mostly made of a touch screen with touch function attached to the display panel, and the touch screen mostly uses capacitive sensing, and its main structure includes driving lines and sensing lines that criss-cross across insulating layers When a finger (or other object) approaches or touches, it will affect the capacitance between the driving line and the sensing line that intersects near the touch point, and the position of the touch point can be identified by detecting the capacitance ...
