Embodiment Construction
[0035] In order to make the above purpose, features and advantages of the touch display screen and its filter assembly more obvious and understandable, the specific implementation of the touch display screen and its filter assembly will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a full understanding of the touch display screen and its filter assembly. However, the touch display screen and its optical filter assembly can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without violating the connotation of the touch display screen and its optical filter assembly, so The touch display screen and its filter assembly are not limited to the specific implementations disclosed below.
[0036] It should be noted that when an element is referred to as being “fixed” to another element, it ...

An optical filter assembly, comprising a substrate, an embossed adhesive layer, a conductive layer, and a filter layer, the substrate includes opposite first surfaces and second surfaces, and the embossed adhesive layer is covered on the first surface of the substrate; The conductive layer is embedded on one side of the embossed adhesive layer, and includes a first conductive pattern and a second conductive pattern spaced apart from each other to form an induction structure, including a conductive grid composed of conductive threads, and the filter layer is covered on the embossed adhesive layer One side includes a light-shielding part and a light-filtering part, the light-shielding part is grid-shaped, includes grid lines intersecting each other and a plurality of grid units, and the light-filtering part includes a plurality of filter units, and each filter unit is accommodated in Correspondingly, in a grid unit; the conductive layer is located between the embossed adhesive layer and the light-shielding part; the above-mentioned filter assembly can be operated by touch and has a light filtering function, which is conducive to reducing the thickness of electronic products and saving materials and assembly costs. At the same time, a touch display screen is provided.
Description
technical field [0001] The invention relates to the field of touch technology, in particular to a touch display screen and a filter assembly thereof. 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 from 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-computer interaction, and then assembled....
