Problems solved by technology
If a two-layer substrate with a substrate containing multiple layers of first electrodes plus another substrate with shielding components 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 , and the multi-layered first electrode substrate needs to be combined after layered manufacturing, the production process is complicated, and the cost of the adhesive between the substrate and the combination is increased
[0003] The area and distance between the first electrode and the second electrode of the traditional single-layer multi-point are almost the same size, because the electrode far from the electrode lead terminal block needs to be electrically connected to the electrode lead through a relatively long lead, and the ITO lead The resistance is large, resulting in inconsistent charging and discharging time of each sensing electrode, which makes the touch screen sensitivity and other performance poor

The invention relates to a conductive electrode structure used for a touch screen. The conductive electrode structure used for the touch screen comprises a plurality of electrode units, wires and lead terminal strips, wherein the distance between a first electrode unit in the electrode units and a corresponding second electrode unit decreases gradually towards the direction of a corresponding lead terminal strip. Due to the fact that the distance between the first electrode unit and the corresponding second electrode unit decreases gradually towards the direction of the corresponding lead terminal strip and capacitance between the first electrode unit and the corresponding second electrode unit increases gradually towards the direction of the corresponding lead terminal strip, approximate balance of charge-discharge time of the electrode units can be guaranteed, the manufactured touch screen can achieve quite even reaction to touch. Furthermore, the invention relates to a touch panel comprising the conductive electrode structure used for the touch screen.
Description
technical field [0001] The present invention relates to the technical field of touch screens, in particular to a conductive electrode structure for a touch screen and a touch panel using the conductive electrode structure. Background technique [0002] Touch screens are widely used in various electronic devices with display screens, such as smart phones, TVs, and PDAs. Common touch panel components usually include one or more layers of emitting / sensing signal electrodes, and a substrate supporting the electrodes. Shielding components and another substrate with scratch resistance, anti-glare, anti-fingerprint / water, anti-reflection, etc. Manufacturing such a touch panel requires laminating two separately fabricated components together. The thickness of the touch panel will be thicker if using a substrate containing multiple layers of the first electrode plus another two-layer substrate with a shielding component and a substrate with scratch resistance, anti-glare, anti-finge...
