1.00。
Second of embodiment according to the present invention, as the light transmittance LT=98% of screen protection glass, at 20 DEG C
Thermal coefficient of expansion TCE=0, meets between the radius of curvature R of light guiding surface 103 and the thickness T of screen protection glass：R/T=-
1.14。
As shown in Fig. 2, screen protection glass 1 according to the present utility model, which can be stablized, is securely supported on the electronics such as mobile phone
In equipment, while obvious invalid dark border is not had using the screen protection glass 1 of the utility model.
Fig. 3 is the screen for including above-mentioned screen protection glass for schematically showing a kind of embodiment according to the present utility model
The structure arrangement side view of curtain module.As shown in figure 3, screen module according to the present utility model includes 1 He of screen protection glass
Display element 2.When passing through eye-observation, imaging region is virtual image screen 3.As shown in figure 3, in the present embodiment, screen
Curtain protective glass 1 is arranged on the right side of 2 display surface of display element.The upright projection of display element 2 is located at screen protection glass 1
Central area, and the gluing black surround of screen protection glass 1 is beyond the above-mentioned upright projection of display element 2, i.e. screen protection glass
The gluing black surround part of glass 1 is with display element 2 without completely corresponding.Mobile phone is applied to when in electronic equipment, screen is protected
Shield glass 1 is covered on display element 2.Specifically, the first surface 101 of screen protection glass 1 is close to display element 2
Display surface is set.As shown in figure 3, virtual image screen 3 is more than the size of 2 display surface of display element, the side of virtual image screen 3
While it is concordant with the side of screen protection glass 1.In the utility model, since the side edge of screen protection glass needs to apply
Glue is covered, so when the screen module of the utility model is loaded in mobile phone when in electronic equipment, gluing on screen protection glass 1
Part forms black surround part seen by person, i.e., the image that human eye actually observes is less than virtual image screen 3 in Fig. 3
Size.
Fig. 4 and Fig. 5 is to schematically show A portions enlarged drawing in Fig. 3.It is aobvious due to being arranged on display element 2 with reference to Fig. 4 and Fig. 5
Show that the screen protection glass 1 above face is provided with light guiding surface 103, and the radius of curvature R of light guiding surface 103 and screen protection glass
1 thickness T meets the restriction of above-mentioned relation formula, when the display light that display element 2 is sent is along from first surface 101 to second
When 102 direction of surface is propagated, it is arranged to the light guiding surface 103 of curved surface irreflexive display light can will occur to be refracted to first
The opposite perimeter in surface 101, and the light of refraction is projected along the direction perpendicular to/substantially vertical second surface 102.
Be arranged such so that user from the outside of second surface 102 of screen protection glass 1 along from shown by arrow direction when, can see
To light guiding surface 103 at the light that reflects so that light guiding surface 103 still can with the corresponding position of above-mentioned non-display area
Enough there is light injection, so, human eye would not observe that obvious invalid black in viewing screen beyond screen protection glass 1
Frame region, but the entirety of screen has active area.Thus one, because the setting of the light guiding surface 103 of curved surface causes people
Observing the black surround in the picture of the virtual image screen 3 observed becomes no longer obvious, is not provided with seeing during light guiding surface 103 than ever
The black surround area observed substantially diminishes.The width of the invalid black surround frame of screen module non-display area formation is reduced, is improved
Imaging surface shows the screen accounting of area, improves viewing experience.In the present embodiment, as shown in figure 5, according to the utility model
The width of actual gluing black surround of screen protection glass 1 be H, the refraction of light path projected by light guiding surface 103 to display element 2
Afterwards, the visual black surround width of human eye physics is obviously reduced as H`, and when the screen module of the utility model is loaded in the electricity such as mobile phone
When being imaged in sub- equipment, that human eye is actually seen is the black surround H`` on virtual image screen 3, i.e. image black surround H``.Thus may be used
Know, due to the relation being provided between light guiding surface 103 and 1 medium spacing T of screen protection glass and radius of curvature R so that according to
Vision black surround (i.e. human eye can be obviously reduced in imaging of the screen module of the utility model when applied to mobile phone when electronic equipment
It was observed that black surround) area.
In addition, light guiding surface 103 can rationally set leaded light under the restriction of -2 ＜ R/T ＜ -0.7 of above-mentioned relation formula
The face type in face 103 and the thickness of screen protection glass, be conducive to do in screen protection glass it is thinner, it is more attractive, use feel
More preferably.
Fig. 6 to Fig. 8 schematically show the optics of other three kinds of embodiments of screen module according to the present utility model into
As schematic diagram.According to Fig. 6 to Fig. 8, screen module according to the present utility model exists in the ratio of radius of curvature R and spacing T
In above range during any change, screen module according to the present utility model can obtain above-mentioned beneficial effect.
The above is only enumerating for specific embodiment of the present utility model, for wherein not detailed description equipment and
Structure, it should be understood that take the existing common apparatus in this area and universal method to be practiced.
The foregoing is merely an embodiment of the utility model, it is not intended to limit the present invention, for
For those skilled in the art, various modifications and changes may be made to the present invention.It is all in the spiritual and former of the utility model
Within then, any modification, equivalent replacement, improvement and so on, should be included within the scope of protection of this utility model.
