Publication number: 20260082792Abstract: 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.Type: ApplicationFiled: September 10, 2025Publication date: March 19, 2026Inventors: Ren-Yuan YAN, Ching-Kai Cho, Jia-Jing Chen
