Problems solved by technology

[0004] The above-mentioned single-layer multi-point design needs to use relatively narrow ITO as the lead in the visible area of ​​the touch screen, but due to the relatively high square resistance of ITO (100-500Ω), usually only 5 inches and 5 inches can be achieved. inch or less, medium and large size structures cannot be carried out

Embodiment Construction

[0026] Please refer to image 3 and Figure 4 , shows a schematic diagram of a wiring structure of a single-layer multi-point capacitive touch screen of an embodiment. The single-layer multi-point capacitive touch screen is provided with a visible area, outside the visible area is the non-visible area of ​​the touch screen, that is, the frame of the touch screen, and the non-visible area can generally be divided into the first end non-visible area (usually That is, the top non-visible area), the second end non-visible area (ie, the bottom non-visible area) and the side non-visible area are well known to those skilled in the art and will not be repeated here. Such as image 3 As shown, the visible area of ​​the single-layer multi-point capacitive touch screen is formed by a plurality of independent electrode units 110 arrayed in multiple rows and columns, wherein each of the plurality of electrode units 110 has wires drawn out.

Abstract

The invention relates to a single-layer multi-point capacitive touch screen comprising a touch panel, and a visible area is arranged on the touch panel, wherein a plurality of independent electrode units arranged in a multi-row multi-column array are arranged in the visible area, and wires are led from the electrode units respectively. The visible area comprises a first end portion visible area, a second end portion visible area and a middle visible area located between the first end portion visible area and the second end portion visible area, wherein the wires of the electrode units in the first end portion visible area are led out of the top of the first end portion visible area, the wires of the electrode units in the middle visible area are led out of one side of the visible area, and the wires of the electrode units in the second end portion visible area are led out of the top of the second end portion visible area. The middle wires of the electrode units of the middle visible area are led out of one side of the visible area, so the lengths of the wires of the middle visible area is short, the total length of the wires of the whole visible area is made to decrease, and thus the resistance value of a whole sensing channel is reduced.

Description

technical field [0001] The invention relates to the field of touch control, in particular to a single-layer multi-point capacitive touch screen. Background technique [0002] Common touch panel components usually include one or more layers of electrodes for transmitting / sensing signals, a substrate for supporting the electrodes, a shielding component and another substrate with scratch resistance, anti-glare, anti-fingerprint / water, anti-reflection, etc. Manufacturing such touch panels requires bonding two separately manufactured components together. If a two-layer substrate with a substrate containing multilayer electrode units plus another substrate with a shielding component and a substrate with scratch resistance, anti-glare, anti-fingerprint / water, anti-reflection, etc. is used, the thickness of the touch panel will be thicker, Moreover, the substrates containing multilayer electrode units need to be fabricated in layers and assembled together, the production process is...
