Abstract
A method for enhancing edge signals of a touch screen is characterized in that the touch screen is a high-transparency handwriting transparent antenna plate which is formed by attaching high-transparency PE base materials and transparent OCA (optical Clear Adhesive) optical cement (metal grid lines with the diameter less than or equal to 50 um), the outermost metal grid lines of the high-transparency handwriting transparent antenna plate are subjected to signal isolation and noise filtering processing through a processing unit, gray copper wires with the diameter less than 50um are adopted, the space between all the grid lines in an effective area is equal, so that line shadows cannot be seen basically by naked eyes, the light transmittance of the antenna plate is facilitated, the extremely fine line shadows are atomized by a diffusion plate of the screen, the grid line shadows cannot be generated when the screen is lighted, PIN communication lines are all arranged outside the AA effective area, and the transparency of the whole antenna plate is not influenced.
Description
Technical Field
The invention relates to the technical field of digital writing, in particular to a method for enhancing edge signals of a touch screen.
Background
With the popularization of 5G, intelligent education and paperless office, digital writing is already reflected in our eyelids. When the electronic pen is used for writing, handwriting is displayed on the transparent antenna plate. However, the handwriting transparent antenna board mode in the prior art is easily interfered by the outside, and particularly, four edge signals of the prior transparent antenna board are affected by an iron frame of a screen, the signals become very weak, and the edge jitter is more severe during writing. The main reason is that the metal wires used by the screen are thick, shadows appear after the screen is lightened, and certain influence is exerted on the vision of a user. The eyes of the user may be injured by the long-term use. Although it is only one-area type, it cannot write the original handwriting normally if it is interfered by the outside and the shadow affects the vision. Thereby causing a waste of resources.
Disclosure of Invention
The invention aims to solve the problems and provides a touch screen edge signal enhancement method which is simple in structure and convenient to use.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a touch screen edge signal enhancement method is characterized in that the touch screen is a high-transparency handwriting transparent antenna board which is formed by attaching high-transparency PE (polyethylene) base materials and transparent OCA (optical Clear Adhesive) optical cement (metal grid lines with the diameter less than or equal to 50 mu m), and the outermost metal grid lines are subjected to signal isolation and noise filtering processing through a processing unit.
As an improvement to the above technical solution, the metal grid lines are multi-coil metal grid lines.
As an improvement to the above technical solution, the metal grid lines are made of gray copper wires smaller than 50 um.
As an improvement to the above technical scheme, all PIN communication lines of the touch screen are routed outside the AA effective area, and it is ensured that the distances between all grid lines of the AA effective area are equal, so as to avoid the occurrence of shadows when the touch screen is lighted.
Compared with the prior art, the invention has the advantages and positive effects that:
the method for enhancing the edge signal of the touch screen can be assembled by adopting a side-in screen and a direct-down screen, has no limit on the size of the screen, and does not need to consider the direct-in type and the side-in type of the screen and the joint alignment of the antenna plate and the silicon steel sheet in the production process. The assembly process is reduced, and partial operation time and later use and maintenance cost are saved. The handwriting transparent antenna plate not only improves the efficiency, but also reduces the manufacturing cost; the silicon steel sheet in the original handwriting transparent antenna plate is removed, the defects that the silicon steel sheet is high in cost and heavy in pollution to the environment in the production process are overcome, and the transparent design effectively reduces resource waste and environmental pollution.
The invention adopts high transparency (PET + OCA optical cement + copper wires with diameter within 50 um), multi-coil equal type to strengthen signal and port control, and adopts gray copper wires with diameter less than 50um, and the space between all grid lines in the effective area is equal, thus the line shadow can not be seen by naked eyes basically, which is beneficial to the light transmission of the antenna plate, and the diffusion plate of the screen is reused to atomize the ultra-thin line shadow, and the grid line shadow can not appear when the screen is lightened. The PIN communication lines are all wired outside the AA effective area, so that the transparency of the whole antenna board is not affected.
