Between zone of reasonableness in.Such as specific in present embodiment, the refractive index of the first optical compensating layer 240 takes 1.75 to be used as specifically
It is bright.
Above-mentioned touch module 200 has at least the following advantages：
Since the first optical compensating layer 240 is set to photosensitive layer 232 toward the surface of first surface 211, and positioned at sense
Between photosphere 232 and transparent conductive oxide film 220, thus etching region and non-etched area reflectivity the difference is that：Etching
Area, reflection and transparent conductive oxide film of first optical compensating layer 240 with 220 interface of transparent conductive oxide film
220 with the reflection of 210 interface of base material；Rather than etching region, the reflection of the first optical compensating layer 240 and 210 interface of base material.By
In the first optical compensating layer 240 refractive index between photosensitive layer 232 refractive index and transparent conductive oxide film 220 refraction
Between rate, therefore the reflectivity difference in etching region and non-etched area can be made smaller, to slow down etching line phenomenon, it might even be possible to
The difference of the two reflectivity is set to be less than the range that human eye can identify, to have the function that eliminate etching line.
For example, the refractive index n1 of the first optical compensating layer 240 takes 1.75, the refractive index of transparent conductive oxide film 220
1.9 are taken, the refractive index of base material 210 takes 1.6.The reflectivity in etching region and non-etched area the difference is that：
Referring to Fig. 4, etching region：The reflection of first optical compensating layer 240 and 220 interface of transparent conductive oxide film
With the reflection of transparent conductive oxide film 220 and 210 interface of base material.Non-etched area：First optical compensating layer 240 and base material
The reflection of 210 interfaces.According to the relationship of reflectivity and refractive index, the first optical compensating layer 240 can be calculated and led with transparent
The reflectivity of 220 interface of oxide film, transparent conductive oxide film 220 and 210 interface of base material reflectivity and
The reflectivity of first optical compensating layer 240 and 210 interface of base material, it is as follows respectively：
R (reflectivity of the first optical compensating layer and transparent conductive oxide film interface)=(1.9-1.75)2/(1.9
+1.75)2=0.17%；
R (transparent conductive oxide film and the reflectivity at substrate interface)=(1.9-1.6)2/(1.9+1.6)2=
0.73%；
R (the first optical compensating layer and the reflectivity at substrate interface)=(1.75-1.6)2/(1.75+1.6)2=

First optical compensating layer 240 substantially reduces the difference in reflectivity of etching region and non-etched area, has the function of slowing down etching line,
By accurately adjusting, the difference of reflectivity can be made to be less than the range that human eye can identify, etching line is eliminated to reach
Effect.
It is the sectional view of the touch module 200 ' in another embodiment, specific to the reality also referring to Fig. 6 and Fig. 7
It applies in mode, in addition to including base material 210 as shown in Figures 1 to 5, transparent conductive oxide film 220, transfer printing type electrically conducting transparent
Film 230 and the first optical compensating layer 240 further include the second optical compensating layer 250.Second optical compensating layer 250 is located at base material
210 first surface 211, and between transparent conductive oxide film 220, the first optical compensating layer 240 and base material 210,
Refractive index of the refractive index of second optical compensating layer 250 between the refractive index and transparent conductive oxide film 220 of photosensitive layer 232
Between.That is, the second optical compensating layer 250 isolation transparent conductive oxide film 220, the first optical compensating layer 240 and base material
210。
At this time etching region and non-etched area reflectivity the difference is that：Etching region, the first optical compensating layer 240 are led with transparent
The reflection of 220 interface of oxide film and transparent conductive oxide film 220 and 250 interface of the second optical compensating layer
Reflection；Non-etched area, the reflection of 250 interface of the first optical compensating layer 240 and the second optical compensating layer.
Specific in Fig. 6 and Fig. 7 illustrated embodiments, the refractive index n2 of the second optical compensating layer 250 is between 1.55 and 1.8
Between.Therefore it is similar between the second optical compensating layer 250 and the first optical compensating layer 240, can reduce etching region with it is non-
The difference of the reflectivity of etching region further slows down etching line phenomenon.
The light transmittance of second optical compensating layer 250 is more than 90%.For example, the light transmittance of the second optical compensating layer 250 can be with
It is 95%.The light transmittance of second optical compensating layer 250 is higher, and light transit dose is bigger, can further slow down etching line phenomenon.
But light transmittance it is bigger when, to the cost of manufacture of the second optical compensating layer 250 and require it is higher, therefore by the second optical compensating layer
250 light transmittance is set greater than in 90% zone of reasonableness.
For example, the refractive index n1 of the first optical compensating layer 240 takes 1.75, the refractive index of transparent conductive oxide film 220
1.9 are taken, the refractive index of base material 210 takes 1.6, and the refractive index of the second optical compensating layer 250 takes 1.65.Etching region and non-etched area
Reflectivity the difference is that：
Referring to Fig. 7, etching region：The reflection of first optical compensating layer 240 and 220 interface of transparent conductive oxide film
With the reflection of 250 interface of transparent conductive oxide film 220 and the second optical compensating layer.Non-etched area, the first optical compensation
The reflection of layer 240 and 250 interface of the second optical compensating layer.According to the relationship of reflectivity and refractive index, first can be calculated
The reflectivity of optical compensating layer 240 and 220 interface of transparent conductive oxide film, transparent conductive oxide film 220 and the
The reflectivity of two optical compensating layers, 250 interface and the first optical compensating layer 240 are anti-with 250 interface of the second optical compensating layer
Rate is penetrated, it is as follows respectively：
R (reflectivity of the first optical compensating layer and transparent conductive oxide film interface)=(1.9-1.75)2/(1.9
+1.75)2=0.17%；
R (reflectivity of transparent conductive oxide film and the second optical compensating layer interface)=(1.9-1.65)2/(1.9
+1.65)2=0.50%；
R (reflectivity of the first optical compensating layer and the second optical compensating layer interface)=(1.75-1.65)2/(1.75+
1.65)2=0.086%.
Therefore, reflectivity difference=0.17%+0.50%*95%-0.086%=of etching region and non-etched area
0.56%.So the first optical compensating layer 240 and the second optical compensating layer 250 substantially reduce etching region and non-etched area
Difference in reflectivity has the function of slowing down etching line, by accurately adjusting, the difference of reflectivity can be enable to be less than human eye institute
The range of identification, to have the function that eliminate etching line.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
