Problems solved by technology

Due to the high resistance of ITO itself and the thin ITO layer during actual deposition, the Rx and Tx made of ITO usually have large impedances. When the touch part and the display part are driven in time, it is easy to cause signal delay and affect Touch Screen Performance

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate, a preparation method thereof, and a capacitive embedded touch screen. Background technique [0002] Capacitive touch screen has become the current mainstream touch screen due to its thinner, higher light transmittance, stronger stability, and support for multi-touch. Among them, the in-cell mode can make the capacitive touch screen thinner and have higher light transmittance. However, since the touch part and the display part of the capacitive touch screen often need time-sharing driving, signal delay (loading) becomes an important factor restricting the performance of touch control and display. [0003] The capacitive in-cell touch screen includes a touch driving electrode layer and a touch sensing electrode layer that usually include insulation. The touch driving electrode layer includes a plurality of touch driving electrodes TX, and the touch sensing ele...
