Problems solved by technology

[0007] Therefore, if the color or white decorative frame in the prior art is used in this integrated capacitive touch screen, the high-thickness decorative frame will affect the circuit fabrication of the projected capacitive touch screen, which is due to the higher thickness of the decorative frame. It will affect the patterning process used and reduce the accuracy of the circuit pattern

Abstract

The invention relates to a decoration frame of a high-precision capacitive touch screen. The decoration frame comprises a main layer and a colored or white scattering layer. The scattering layer and the main layer are sequentially arranged on a transparent baseplate, and the main layer is arranged within the range of the scattering layer. The scattering layer is manufactured by adopting yellow light process. Since the scattering layer is manufactured by the yellow light process, edges of the whole decoration frame have smooth lines, high imaging precision and fine appearance effect. Peripheral lines are covered or homogenized by the main layer, and then are further blurred through the colored or white scattering layer, and accordingly graphs on the peripheral lines are difficult to identify when observed from the other side of the transparent baseplate with naked eyes, the decoration frame is colored or white uniformly, and has fine appearance effect. The scattering layer and the main layer can both be arranged to be thin, and are applicable for manufacturing of an integral capacitive touch screen.

Description

technical field [0001] The invention relates to a decorative frame, in particular to a high-precision capacitive touch screen decorative frame. Background technique [0002] Capacitive touch screens have many advantages such as high transparency, no need for force to apply pressure, and resistance to harsh external environments. They can be applied to various consumer electronic products such as mobile phones, tablet computers, and notebook computers. [0003] In the existing design, the capacitive touch screen is generally formed by pasting a sensing substrate and a protective glass. Among them, the sensing substrate includes sensing electrodes, peripheral circuits and other circuits for realizing the touch sensing function composed of patterned film layers; the protective glass covers the outside of the sensing substrate. When the capacitive touch screen is installed in an electronic product, the protective glass is not only It plays the role of protecting the internal ci...
