What is visually felt should be also what is shone exposed to outer non-display area 411, effectively prevent naked eyes from perceiving non-luminous exposure
The presence of non-display area 411 outside (i.e. naked eyes will not perceive black surround presence).Therefore, cause to cover due to because installation error
200 upright projection on display screen 400 of layer is not covered with whole non-display areas 410, aobvious exposed to outside non-so as to be formed
When showing region 411, by setting transition face 130, the cover board 100 comprising the transition face 130 is made to play the role of convex lens, from mistake
The reverse extending line 404 for crossing the emergent ray 403 that face 130 transmits intersects with exposed to outer non-display area 411, is formed
This is exposed to the illusion that outer non-display area 411 also shines, it is ensured that naked eyes visually perceive the presence less than black surround.
Refering to Fig. 7, transition face 130 is arc-shaped curved surface, and transparent surface 150 and mounting surface 140 are in plane in overall profile
Shape.In other embodiments, refering to Fig. 8,140 overall profile of mounting surface is two planes with respect to the bending song that bending is formed
Face, i.e. mounting surface 140 include first module face 141 and second unit face 142, and first module face 141 and second unit face 142 are equal
For plane, the one end in second unit face 142 is connected with first module face 141, the other end and transition face in second unit face 142
130 connections, the angle between first module face 141 and second unit face 142 is α, and wherein the value range of α is 90 °≤α ＜
180°.When the value of α is 90 °, first module face 141 and second unit face 142 are vertical, it will be understood that when the value of α is
At 180 °, first module face 141 and second unit face 142 are coplanar, i.e., mounting surface 140 is in planar feelings in overall profile
Shape.
By setting transition face 130, transition face 130 is arc-shaped curved surface, can not only make to be exposed to outer non-display area
411 form luminous illusion, it is ensured that naked eyes visually perceive the presence less than black surround；Also the thickness of cover board 100 can be reduced, is accorded with
The development trend of 100 lightening design of closing lid plate；Meanwhile Sharp edge present on also eliminating cover board frontside edge, avoid rib
While the effect stress in external impacts is concentrated and destroyed, and then cover board 100 is damaged, improve 100 shock resistance of cover board and shatter-resistant
