  • Touch display device including buffer layer for accuracy of touch sensing
    Patent number: 11644913
    Abstract: A touch display device includes a display panel, a conductive layer, an optical matching layer and a buffer layer. The display panel comprises a first substrate, a second substrate and a display medium layer. The first substrate comprises a first surface and a second surface, the second substrate is disposed opposite to the first substrate, and the display medium layer is disposed between the second surface of the first substrate and the second substrate. The conductive layer is disposed on the first surface of the first substrate, and comprises a plurality of sensing electrodes. The optical matching layer is disposed between the conductive layer and the first surface of the first substrate. The buffer layer with a thickness greater than or equal to 50 ? and less than or equal to 3000 ? is disposed between the optical matching layer and the first surface of the first substrate.
