  • Publication number: 20240152241
    Abstract: An embodiment of the present invention provides a touch display panel and a touch display device including an underlay substrate and touch electrodes. The touch electrodes include a plurality of pattern electrodes. Adjacent ones of the pattern electrodes along are arranged in a staggered arrangement a first direction. The pattern electrode has a first width along the first direction and has a second width along a second direction. The second width is greater than the first width. Changing an arrangement of the pattern electrodes reduces touch lead lines in the display panel, improves a touch precision of the display panel, and lowers a manufacturing cost.

  • Patent number: 11947754
    Abstract: The present disclosure provides a capacitive touch screen device, a reading method thereof, and a display device. A plurality of pixel units is divided into a plurality of touch detection regions. A touch sensing unit is configured for each touch detection region to detect charges in the touch detection region, thereby reducing a number of touch sensing units and independently collecting the charge detected by each touch sensor unit, further improving sensing accuracy. A plurality of read lines is added to correspond to each column of read units, simplifying in-plane lines.

  • Publication number: 20240069391
    Abstract: An array substrate and a touch display panel are provided. The array substrate includes a substrate, a pixel unit, a pixel electrode, and a capacitor electrode. An orthographic projection of the capacitor electrode on the substrate at least partially overlaps an orthographic projection of a subpixel electrode on the substrate. By arranging the capacitor electrode in a subpixel area and by making a capacitance value of a storage capacitor corresponding to the subpixel electrode greater than a capacitance value of a storage capacitor corresponding to a main pixel electrode and a common electrode, touch effects of a display panel can be improved.
