Light L energy proportions on the frontier district 1000a of 37 ° of lower splicing display devices 1000.
The design of splicing display device 1000 is preferably, the centre position of frontier district 1000a (such as:Corresponding diagram 5 is to Fig. 8
Frontier district on position be about 500 μm) on brightness it is slightly higher, and the both sides of frontier district 1000a (such as：Corresponding diagram 5 is to Fig. 8's
Position is about 0 μm and 1000 μm on the 1000a of frontier district) on brightness it is lower slightly, the both sides brightness of such frontier district 1000a just will not
Influence the display brightness of viewing area A1, A2.It can be seen that by Fig. 5 to Fig. 8, when acute angle theta is from when increasing to about 37 ° for about 35.5 °, figure
Curve shown in 8 slightly tilts (as Fig. 8 dotted lines enclose place) in the left and right sides, it is represented on the both sides of frontier district 1000a
Brightness raises, and will influence the display brightness of viewing area A1, A2；Also, from Fig. 5 to Fig. 8, when acute angle theta increases from about 35.5 °
During to about 37 °, the light integral energy on the 1000a of frontier district also declines, and is unfavorable for the display effect of frontier district 1000a.It is comprehensive
The data of Fig. 5 to Fig. 8 know that as shown in figs. 5 and 8, when acute angle theta is about 35.5 ° and 36 °, curve can not in left and right sides portion
It can tilt, and peak of curve can maintain about 1.2 or so (the light integral energy i.e. on the 1000a of frontier district is high).Thus can demonstrate,prove,
Acute angle theta 1 is preferably designed more than 0 degree and less than or equal to about in the range of 36 degree, with the display effect of sharp edge battery limit (BL) 1000a

Middle abscissa simulation backlight enters the angular of display panel 100/200, and ordinate represents energy normalization relative intensity (no list
Position).The data of Fig. 9 A to Fig. 9 D can be demonstrate,proved, if acute angle theta is 34 ° and 35.5 °, under 0 ° to 45 ° of visual angle, on the 1000a of frontier district
Light L all has enough brightness.In other words, when user watches splicing display device 1000 with a variety of visual angles, spell
Connect the frontier district 1000a of display device 1000 brightness enough and display effect is good.
However, the present invention, which is not intended to limit acute angle theta 1, has to design in the scope more than 0 degree and less than or equal to about 36 degree
It is interior.Be not easy to be formed the acute angle theta 1 of low-angle, and/or frontier district 1000a width Wb it is larger in the case of, acute angle theta 1 is also optional
Selecting property is more than 36 degree.For example, in the case of pixel wide Wps of the width Wb of frontier district 1000a more than 3 times, if making H1
=0, according to the thickness tg of general upper substrate 10, the thickness tp of upper polarizer P1 and above-listed relational expression (1), angle of reflection θ can be big
In 36 degree；At this time, the light distribution on the frontier district 1000a of tiled display panel 1000 is easily irregular.Therefore, in frontier district 1000a
Width Wb it is larger in the case of (such as:Wb is more than 3 times of Wb), it is preferred that optionally making H1 be more than 0, so that border
Light distribution on area 1000a can be more uniform.It is worth noting that, while H1 is increased, 120 easy light leak of the second sub-pixel,
Therefore, can optionally be set on the side 310c-1 of transparent base 310 brightness decay piece 152 (such as:Shown in Fig. 2),
To reduce influence of the light leak of the second sub-pixel 120 to the display effect of the first sub-pixel 110.Brightness decay piece 152 refers to pair
Various optical wavelength have the neutral colour filter (neutral density filter) of about identical penetrance.Brightness decay piece
Depending on the visual actual demand of 152 penetrance size.In the present embodiment, the penetrance of brightness decay piece 152 is no more than half
The penetrance of penetrating and half-reflecting piece 330A.For example, if the unit area brightness of the second sub-pixel 120 close to splicing seams S
For N times of the unit area brightness of the first sub-pixel 110, then the penetrance of brightness decay piece 152 may be designed as (1/N), but this
Invention is not limited, and is also not necessarily limited to integer.
Similarly, the extending direction x of the extending direction d2 and bottom surface 310b of the inclined-plane 310a-2 of transparent base 310 are accompanied sharp
Angle θ 2.Acute angle theta 2 can be also designed in proper range according to aforesaid way.For example, H1=0 (such as：Splicing display device
1000 integral thickness T are optimized, and transparent base 310 does not have side 310c-1,310c-2) in the case of, acute angle theta 2 is preferably
Design more than 0 degree and be Less than or equal to about 36 degree in the range of；In acute angle theta 2 and/or the frontier district for being not easy to be formed low-angle
The width Wb of 1000a it is larger (such as：It is more than 3 times of pixel wide Wp in the width Wb of frontier district 1000a) in the case of, acute angle
θ 2 is also alternative to be more than 36 degree.In addition, similarly, while H1 is increased, 220 easy light leak of the 4th sub-pixel, therefore, also may be used
In optionally set on the side 310c-2 of transparent base 310 brightness decay piece 154 (such as:Shown in Fig. 2).Brightness decay piece
154 optical characteristics and function is similar with the optical characteristics and function of brightness decay piece 152, is just no longer repeated in this.
