Problems solved by technology

However, maintaining this coverage leaves a large gap between adjacent electrodes, reducing the effect of touch sensing
If the user's fingers are relatively slender or the user uses a stylus, the electrodes close to the touch point may not be able to sense the change in capacitance, and the control circuit cannot calculate the correct touch position through interpolation, resulting in a tactile sensation. Incorrect
As the design of the stylus becomes thinner and thinner, the touch panel is bound to be more and more affected by this shortcoming in order to meet the requirements

Abstract

A projected capacitive touch panel, which includes: a plurality of strip-shaped first electrodes arranged side by side; and a plurality of meander-shaped second electrodes arranged at intervals, wherein each second electrode includes several induction line. The sensing lines of each second electrode are spaced apart from each other and electrically connected to each other, and extend in a meandering form along a length direction perpendicular to the first electrode. The extending of the sensing lines in a meandering manner can reduce the distance between each other, thereby improving the effect of touch sensing.

Description

Technical field [0001] The invention relates to a touch panel, in particular to a projected capacitive touch panel which can increase the accuracy of touch. Background technique [0002] A projected capacitive touch panel usually includes two sets of transparent electrodes (X and Y) and a plurality of driving lines connected to the transparent electrodes, wherein the two sets of transparent electrodes are respectively arranged on two different substrates or are arranged together On a single substrate. [0003] Please refer to figure 1 As shown, an existing projected capacitive touch panel includes a set of X electrodes (X1 to X4) and another set of Y electrodes (Y1 to Y4) perpendicular to the set of X electrodes. The X and Y electrodes are connected to a control circuit through a plurality of driving lines to form a sensor array. The control circuit can sense the capacitance change between the X electrode and the Y electrode to determine the position touched by a user. [0004] Ea...
