  • COLOR FILTER SUBSTRATE, IN-CELL OPTICAL TOUCH DISPLAY PANEL INCLUDING THE SAME AND MATERIALS OF INFRARED FILTER LAYER
    Publication number: 20140145976
    Abstract: A color filter substrate for an in-cell optical touch display panel is provided, which includes a substrate, a visible-light shielding structure, a color filter layer and an infrared filter layer. The visible-light shielding structure is disposed on the substrate to define sub-pixel regions and touch sensor regions of the substrate. The color filter layer covers the sub-pixel regions. The infrared filter layer covers the touch sensor regions. The infrared filter layer is made of a single infrared-light permeable material, which has a light transmittance in infrared-light wavelength range greater than a light transmittance in visible-light wavelength range. An in-cell optical touch display panel including the color filter substrate and materials of the infrared filter layer are also provided.
