Abstract
A touch panel including a transparent substrate and a first sensing layer is provided. The transparent substrate has a first surface and a second surface opposite to the first surface. The second surface has a light exporting pattern. The first sensing layer is disposed on the first surface. An electronic apparatus with the touch panel is also provided.
Claims19
A touch panel, comprising:
- a transparent substrate, having a first surface and a second surface opposite to the first surface, wherein the second surface has a light exporting pattern;
- and
- a first sensing layer, disposed on the first surface, the first sensing layer comprising:
- a plurality of first sensing lines directly disposed on the first surface and extending along a first direction,
- wherein the touch panel is a first touch panel disposed on a side of a display panel, and a second touch panel is disposed above a top of the display panel, the transparent substrate and the second touch panel are independent from and spatially separated from the display panel, the light provided by a light source module is first emitted into the display panel and then emitted into the transparent substrate and the second touch panel from the display panel, and the light is scattered out of the transparent substrate from a position of the first surface corresponding to the light exporting pattern.

The touch panel as claimed in claim wherein the light exporting pattern is distributed over entire second surface.
An electronic apparatus, comprising:
- a body, comprising at least one light source module and a display panel;
- a touch panel comprising:
- a transparent substrate, having a first surface and a second surface opposite to the first surface, wherein the second surface has a light exporting pattern, and light provided by the light source module enters the transparent substrate and scatters from a position of the first surface corresponding to the light exporting pattern;
- and
- a first sensing layer, disposed on the first surface, the first sensing layer comprising:
- a plurality of first sensing tines directly disposed on the first surface and extending along a first direction,
- wherein the touch panel is a first touch panel disposed on a side of the display panel, and a second touch panel is disposed above a top of the display panel, the transparent substrate and the second touch panel are independent from and spatially separated from the display panel, the light provided by the light source module is first emitted into the display panel and then emitted into the transparent substrate and the second touch panel from the display panel, and the light is scattered out of the transparent substrate from a position of the first surface corresponding to the light exporting pattern.
