If be appreciated that enclosure body transmitance it is very big, the light for reflecting to form shade is less, imaging capability compared with
Weak, hatching effect is not apparent relatively at this time；If the transmitance very little of enclosure body, light are irradiated into from first surface
The light of enclosure body is also seldom, further the second surface through substrate reflect be used to form shade light it is then less,
Hatching effect is not apparent relatively yet at this time；And if the transmitance of enclosure body is not especially greatly nor especially small feelings
Condition then has certain light to be capable of forming shade, then obvious to the influential effect of appearance, therefore, specifically, working as shell sheet
The transmitance of body is specifically as follows 2%~50% less than 50%, more specifically can be 2%~40%, 2%~20% etc., such as
2%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50% etc., improve the better effect of shade.
It is appreciated that the material of above-mentioned enclosure body can be ceramics.Specifically, ceramics usually have certain transmission
Rate, ambient, which is irradiated on ceramic base material, can occur to transmit and reflect, and thus picture and text layer easily generates shadow problem, and passes through
High transmission region is set, after ambient can be made to be irradiated to high transmission region, reflex is weaker, and transmission effect is stronger,
To destroy the formation condition of shade, hatching effect is effectively eliminated.Specifically, ceramic base material can be zirconia ceramics substrate,
Color can white etc..
It is appreciated that so that the transmitance in high transmission region is not particularly limited more than or equal to 50% specific method,
As long as the reflex in high transmission region, enhancing transmission effect can be weakened.In some specific embodiments, can by

The appearance of apparatus casing is more preferably.
It is appreciated that be formed with the high transmission region of the first antireflective coating reflectivity can according to actual operation requirements into
Row adjustment.Specifically, the reflectivity in the high transmission region can less than 10% (it is specific such as 9%, 8%, 7%, 6%, 5%,
4%, 3%, 2%, 1%, 0% etc.).Ambient reflects less in high transmission region as a result, and transmission is more, can not be imaged, from
And it can effectively eliminate edge shadow.
As long as it is appreciated that the specific size in high transmission region can make human eye it can be seen that picture and text layer sharpness of border i.e.
Can, it can be adjusted flexibly according to the reflectivity etc. of enclosure body.For example, the high transmission region being located on the outside of picture and text layer can basis
The outer edge line of picture and text layer extends to the outside, and the high transmission region being located in picture and text layer in hollow out figure then can be according to hollow out figure
The edge line of shape extends to the outside or can be just to divide human eye clearly to the specific size of contract to contract
Distinguish the predetermined size on the boundary of picture and text layer, it can also be more slightly larger than above-mentioned predetermined size.Specifically, can be base according to picture and text layer
Standard to contract or extends to the outside 10%~20%, (it is specific such as 10%, 11%, 12%, 13%, 14%, 15%, 16%,
17%, 18%, 19%, 20% etc.), in the range, human eye can clearly differentiate the boundary of picture and text layer, imitate without edge shadow
Fruit.
