Abstract

An optical filter assembly comprises a substrate, a light-filtering layer, a first conducting layer and a second conducting layer. The light-filtering layer is directly formed on the first surface of the substrate, and first electric conduction patterns and second electric conduction patterns are exposed. All projections, on the light-filtering layer, of electric conduction silk-covered wires of the first conducting layer and the second conducting layer fall on grid wires. The width of the electric conduction silk-covered wires is equal to or smaller than that of the grid wires. According to the optical filter assembly, an induction structure is formed by the first conducting layer and the second conducting layer, so that the optical filter assembly is operated in a touching mode and beside has the function of light filtering. Reduction of the thickness of an electronic product is facilitated, and material and assembly cost are further saved. The first electric conduction patterns and the second electric conduction patterns are exposed, and therefore, subsequent manufacturing of electrode leading wires and binding among a flexible printed circuit board and the electrode leading wires are facilitated. Meanwhile, the width of the electric conduction silk-covered wires can be increased, and the electric conduction capacity of the conducting layers is improved. Meanwhile, the invention provides a touch display screen.

Description

technical field [0001] The invention relates to the technical field of plane display, in particular to an optical filter assembly and a touch display screen using the optical filter assembly. Background technique [0002] A touch screen is an inductive device that can receive input signals such as touch. The touch screen has endowed information interaction with a new look and is a very attractive new information interaction device. The development of touch screen technology has aroused widespread concern in the information media circles at home and abroad, and has become a rising high-tech industry in the optoelectronic industry. [0003] Currently, electronic products with a touch display function include a display screen and a touch screen located on the display screen. However, as a component independent of the display screen, the touch screen needs to be ordered according to the size of the display screen when it is used in some electronic products that realize human-c...
