Abstract

The present invention relates to a touchable sensing matrix unit, a co-constructed active array substrate having the touchable sensing matrix unit and a display having the co-constructed active array substrate. The touchable sensing matrix unit is formed on the co-constructed active array substrate and has multiple first sensing and transmitting wires and multiple second sensing and transmitting wires. The first and second sensing and transmitting wires are conductive and cyclic, intersect to form an angle, and sandwich an insulation layer formed therebetween.

Description

technical field [0001] The present invention relates to an active array display integrating touch functions, in particular to a touch sensing matrix arranged on a common configuration active array, the wire wiring of the touch sensing matrix includes a plurality of first sensing conductive lines and a plurality of A second induction conduction line is interlaced with each other to form an induction conduction matrix with a certain angle, conductivity and certain periodicity. Background technique [0002] Due to the sophistication of touch panels, the yield rate of touch panels has increased and the touch accuracy has become more accurate. Touch panels can be divided into electromagnetic, resistive, capacitive, and optical (infrared, ultrasonic, etc.) based on the principle of touch sensing. )etc. [0003] In order to provide user input functions for thin, light and miniaturized electronic products, it is a feasible space-saving method to superimpose a touch panel on the scr...

Problems solved by technology

[0010] The above two existing touch display panels can indeed integrate the touch panel into a flat-panel display to realize a thinner touch display, but the manufacturing process and structure of the display panel must be changed. Once the display panel manufacturing process and The first challenges faced by the structure are nothing more than the reduction of the yield rate and the increase of the cost of the manufacturing process; Figure 26 In the shown resistive touch display panel, although the upper transparent electrode on the spacer 93 is used as a means of touching the two metal pads to change the voltage value, the spacer 93 must be separated from the TFT array substrate, and the TFT array Each pixel electrode of the substrate must additionally form two metal spacers 971, such as Figure 27 As shown, and additional auxiliary lines for the X-axis and Y-axis not only reduce the visible area of ​​the pixel electrode but also complicate the manufacturing process of the TFT array substrate

[0011] In addition, in the center, periphery and corner of the pixel display area of ​​the glass substrate, because the pressure sensitivity and deformation will be different, the pressure sensitivity is not easy to correct, and it cannot form multi-finger multi-touch sensing, which is also an important technology. defect

[0012] Similarly, the electromagnetic induction touch display panel must also add the first and second direction wires to the color filter substrate manufacturing process structure, so the manufacturing process steps are also changed, the manufacturing process is more complicated, and the number of light rays and costs are greatly increased.
