Abstract
A touch display panel having a plurality of light emitting elements; a plurality of color filters formed at positions corresponding to the plurality of light emitting elements; and an infrared fluorescent pattern comprising a plurality of individual infrared fluorescent cell patterns formed at positions corresponding to at least some of the plurality of color filters; and an infrared control film positioned on a light emitting surface of the display panel.
Claims17
A touch display device, comprising:
- a display panel including a plurality of light emitting elements;
- a plurality of color filters formed at positions corresponding to the plurality of light emitting elements;
- and an infrared fluorescent pattern comprising a plurality of individual infrared fluorescent cell patterns formed at a position overlapping at least some of the plurality of color filters;
- and
- an infrared control film positioned on a light emitting surface of the display panel,
- wherein the infrared control film includes:
- a base film;
- a first conversion layer formed on the base film to convert infrared light into linearly polarized light;
- a second conversion layer delaying infrared light converted into the linearly polarized light by a ¼ wavelength through the first conversion layer;
- and
- an adhesive layer coupling the second conversion layer to the display panel.
