  • Publication number: 20260082792
    Abstract: A touch display module comprises a touch-sensing layer and an organic light-emitting diode display. The touch-sensing layer comprises a plastic substrate, a first metal mesh electrode layer, and a second metal mesh electrode layer. The thickness of the plastic substrate is 10 ?m to 400 ?m. The plastic substrate has a first refractive index and a second refractive index in different directions, and a difference (birefringence) between the first refractive index and the second refractive index is 0 to 0.0001. The first metal mesh electrode layer is disposed on the first surface. The second metal mesh electrode layer is disposed on a second surface, wherein the second surface is facing away from the first surface. The organic light-emitting diode display is disposed on one side of the touch-sensing layer. The maximum black level luminance of the touch display module is 0.0001 cd/m2 to 0.0005 cd/m2.

  • Patent number: 11829546
    Abstract: The disclosure provides a border touch module, including a cover plate, a shielding layer, a first adhesive layer, a sensing electrode layer, a second adhesive layer, an opaque adhesive, and a backlight layer. The shielding layer is disposed below the cover plate. The first adhesive layer is disposed below the shielding layer. The sensing electrode layer is disposed below the first adhesive layer. The second adhesive layer is disposed below the sensing electrode layer. The opaque adhesive is disposed below the sensing electrode layer. The backlight layer is disposed below the opaque adhesive and is in the same plane as the second adhesive layer. The shielding layer has a backlight pattern, and the opaque adhesive has a light source hole. When the backlight layer is in the state of driving backlight, the light illuminates the backlight pattern of the shielding layer through the light source hole.
