Abstract
A touch panel is provided. The touch panel includes a first substrate and a luminous flux adjusting portion. The first substrate has a top surface, in which the top surface has at least one semi-transparent area. The luminous flux adjusting portion is disposed on the first substrate and located in the at least one semi-transparent area, in which the luminous flux adjusting portion has a continuous light-impermissible pattern. Embodiments of the present invention uses the luminous flux adjusting portion to control the luminous flux of the semi-transparent area for achieving good consistence and adjustability of the luminous flux of the semi-transparent area.
Claims20
A touch panel, comprising:
- a first substrate having a top surface, wherein the top surface has at least one semi-transparent area;
- a luminous flux adjusting portion disposed on the first substrate and located in the semi-transparent area, wherein the luminous flux adjusting portion has a continuous light-impermissible pattern;
- and
- a colored ink layer disposed above the luminous flux adjusting portion to reflect light emitted from the semi-transparent area.
A touch panel, comprising:
- a first substrate having a top surface, wherein the top surface has at least one semi-transparent area;
- and
- a luminous flux adjusting portion disposed on the first substrate and located in the semi-transparent area, wherein the luminous flux adjusting portion has a continuous light-permissible pattern,
- wherein the continuous light-permissible pattern is a spiral pattern or a radiating pattern, and the spiral pattern or the radiating pattern is constructed by a continuous patterning line, and
- wherein the continuous patterning line has a starting point, and a line width of the continuous patterning line is gradually increased along the continuous patterning line from the starting point.
A touch panel, comprising:
- a first substrate having a top surface, wherein the top surface has at least one semi-transparent area;
- and
- a luminous flux adjusting portion disposed on the first substrate and located in the semi-transparent area, wherein the luminous flux adjusting portion has a continuous light-impermissible pattern,
- wherein the continuous light-impermissible pattern is a spiral pattern or a radiating pattern constructed by a continuous patterning line, and
- wherein the continuous patterning line has a starting point, and a line width of the continuous patterning line is gradually decreased along the continuous patterning line from the starting point.
