  • Touch display module
    Patent number: 11703966
    Abstract: A touch display module includes a touch device and a polarizing element. The polarizing element includes a polarizer and a retardation film assembly. The retardation film assembly has a polarization ellipticity value (e-value), and the absolute value of the e-value is greater than 0.8. A reflection rate of the polarizing element is less than 6%, and a total reflection rate of the touch device and the polarizing element is less than 7%.

  • Integrated touch module and touch display device having the same
    Patent number: 11561635
    Abstract: An integrated touch module and a touch display device are provided. The integrated touch module has a touch sensing structure formed on a polymer film. The polymer film, a liquid crystal phase retardation layer, and a linear polarizing layer constitute a circular polarizing element. The average reflectance of the circular polarizing element in the visible light range is less than 5%, and the standard deviation of the reflectance is less than 0.2%. The touch display device includes the integrated touch module.
