Substrate 240 and polymeric layer 250 are included, polymeric layer 250 is located on substrate 240, and polymeric layer 250 is formed for hydrophobic material.It is poly-
It closes and fluted 251 is opened up in nitride layer 250, barrier material 162 is liquid paint, and liquid paint is filled in groove 251.It is not powered on
When, liquid paint is located in groove 251, and most of all band light can penetrate electric paper display 120 at this time.After energization, liquid
State pigment is uniformly distributed on polymeric layer 250, and infrared light can pass through at this time.When liquid paint is located in groove 251, at this time entirely
Band of light can pass through, for identifying fingerprint.When liquid Color is uniformly distributed on polymer 250, infrared light can pass through at this time, use
In identification vein.
Above-mentioned electronic equipment 10 and its back shroud module 100 at least have the following advantages：
It picks up or lifts with back shroud module 100 when detecting that motion state changes, such as from stationary state
Electronic equipment 10 when, the identifying system of back shroud module 100 will be started.By being controlled whether the energization of coordination electrode 161
The distribution situation of barrier material 162 processed when 162 uniform barrier electrode 161 of barrier material, allows infrared light, photoelectricity two
Pole pipe image acquiring sensor 130 can first identify the vein pattern of user.It is compared after the completion of the acquisition of vein pattern, after coincideing
The distribution situation of barrier material 162 is controlled, when barrier material 162 is assembled, most of all band light can pass through, and carry out surface line
The acquisition of road pattern, and then to the comparison of surface pattern pattern, vein and surface pattern pattern all coincide if to electronic equipment
10 are waken up and are unlocked.There is no need to be acquired the switching of light by way of increasing and decreasing optical filter, and need not be by finger
Specific position is placed on, the convenience of acquisition light switching can be effectively improved.
Embodiment described above only expresses the several embodiments of the utility model, and description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for 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.
