Embodiment Construction
[0024] One of the embodiments of the present invention is shown in FIG. 1 : a touch-sensitive liquid crystal display 100 for detecting the leakage current of touch electrode lines. The liquid crystal display 100 has a TFT-LCD screen 110, the TFT-LCD screen has a TFT array substrate glass 111 and a common electrode substrate glass 112, and the TFT array substrate glass 111 has N display scanning electrodes 121 and M display signal electrodes 122. N rows of metal touch electrode lines 131 and m columns of metal touch electrode lines 132 are prepared 111 on the glass of the TFT array substrate. The touch electrode lines 131 and 132 have lead-out pins from the same side as the display electrodes 121 and 122 respectively, and the common electrode There is an ITO common electrode 140 on the substrate glass 112 . The display scan electrodes 121 of the liquid crystal display screen 110 are connected to the display driving circuit 151 , the display signal electrodes 122 are connected t...
