  • Capacitive Touch Screen Capable of Reducing Side Light Reflection
    Publication number: 20210157445
    Abstract: A capacitive touch screen, having a first transparent substrate provided with a touch circuit layer. The touch circuit layer is provided with first and second electrodes and a jumper portion. The touch screen is further provided with an insulating layer. The insulating layer is continuously disposed in an entire transparent touch area of the touch screen, and is provided with through holes at the jumper portion to form a jumper connection of the second electrode. The touch screen further includes a shielding layer sandwiched between the first transparent substrate and the touch circuit layer, and contains multiple shielding blocks. The shielding blocks correspond to the through holes, and the contours of the shielding blocks are formed by expanding the contours of the through holes outwards. The capacitive touch screen can effectively reduce side light reflection on an edge slope of the insulating layer, thereby avoiding interference with display.
