Abstract

A touch apparatus including a first substrate, a touch sensing structure, an insulation layer, a driving electrode, an electrochromic layer, a reflective electrode and a second substrate stacked sequentially along a direction is provided. The driving electrode and the reflective electrode are used to drive the electrochromic layer. The driving electrode is contacted with the insulation layer. The insulation layer has a thickness T 1 in the direction. The first substrate has a thickness T 2 in the direction. T 1<( T 2/10).

Claims (20)

1. A touch apparatus, comprising:

a first substrate;

a touch sensing structure;

an insulation layer;

a driving electrode;

an electrochromic layer;

a reflective electrode; and

a second substrate, wherein the first substrate, the touch sensing structure, the insulation layer, the driving electrode, the electrochromic layer, the reflective electrode and the second substrate are stacked sequentially along a direction; the driving electrode and the reflective electrode are used to drive the electrochromic layer; the driving electrode is contacted with the insulation layer; the insulation layer has a thickness T 1 in the direction; the first substrate has a thickness T 2 in the direction; and T 1 <(T 2 /10).

2. The touch apparatus as claimed in claim 1 , wherein T 1 ≦100 micrometers.

3. The touch apparatus as claimed in claim 1 , wherein the touch sensing structure comprises:

a plurality of first sensing patterns; and

a plurality of second sensing patterns, the first sensing patterns and the second sensing patterns are alternatingly arranged and belong to the same film layer.

4. The touch apparatus as claimed in claim 1 , wherein the touch sensing structure comprises:

a plurality of first sensing patterns;

an insulation layer, disposed on the first sensing patterns; and

a plurality of second sensing patterns, covering the insulation layer, and interlaced and electrically isolated with the first sensing patterns.

5. The touch apparatus as claimed in claim 1 , wherein the driving electrode is a transparent electrode and covers the electrochromic layer entirely.

6. The touch apparatus as claimed in claim 1 , wherein the reflective electrode totally reflects and covers the electrochromic layer entirely.

7. The touch apparatus as claimed in claim 1 , wherein when the electrochromic layer is enabled, the electrochromic layer is rendered a diming state; and

when the electrochromic layer is not enabled, the electrochromic layer is rendered a light transmissive state.
