TOUCH CONTROL LIQUID CRYSTAL DISPLAY DEVICE

摘要

One inventive aspect is a touch control liquid crystal display device. The device includes a color film substrate, a thin film transistor array substrate, and a liquid crystal layer between the color film substrate and the thin film transistor array substrate. The color film substrate includes a grid-shaped black matrix layer, a touch control layer, and a color film layer. The touch control layer includes metal grid electrodes in a rectangle, where the metal grid electrodes include metal lines intersecting transversely and vertically. In addition, the metal grid electrodes include drive electrodes and sense electrodes. The drive electrodes are connected together through first metal connection lines in a first direction, and the sense electrodes are connected together through second metal connection lines in a second direction. In addition, the projection of the metal grid electrodes falls into the projection of the black matrix layer in the light transmission direction.
