On height.Wherein, when bent angle alpha is identical, bending position is more remote with the incident side in mixed light area 42,
The height that the mixed light area 42 increases in a first direction is higher.
For example, it is assumed that during the junction that bending position is mixed light area 42 with light guide zone 41, i.e., entirely
When mixed light area 42 bends, then, when bent angle alpha is 90 °, the mixed light area 42 is in second direction
On length reduction at most, but the height of light conducting plate structure 4 also increases at most, that is, increase the mixed light area 42
Length d3, and when the matching relationship in view of light-source structure 3 and light conducting plate structure 4, the light source is tied
Structure 3 will further result in overall increasing in a first direction.
And as shown in figure 3, when bent angle alpha is 180 °, mixed light area 42, light-source structure 3 etc. are
Plane setting structure is kept, only increases the thickness of the mixed light area 42 or light-source structure 3, so as in first party

Lightening growth requirement.
Additionally, for the embodiment shown in Fig. 3, i.e. mixed light area 42 are towards in the case of top curved, by
Need the panel construction 1 of light conduction to top directly in light guide zone 41, so that control mixed light area
42 bending position and angle of bend, to guarantee that it is effective that mixed light area 42 and light-source structure 3 will not be entered
Inside viewing area 10, it is to avoid above-mentioned light conduction is caused to block and harmful effect.
2nd, bending direction
Except shown in Fig. 2A, Fig. 2 B and Fig. 3 towards in addition to 4 top curved of light conducting plate structure, mixed light
At least a portion in area 42 can be with the bottom bend towards light conducting plate structure 4.Such as Fig. 4 is according to one
A kind of light conducting plate structure shown in the three of exemplary embodiment and its cooperation schematic diagram with light-source structure, such as
Shown in Fig. 4, at least a portion in mixed light area 42 can be towards the bottom bend of light conducting plate structure 4 and curved
Bent angle [alpha] can be 180 ° in Fig. 4 (it is of course also possible to be that other between 0 °～180 ° are any
Angle (not including 0 °)), and light-source structure 3 is located at 41 bottom side of light guide zone and parallel to the mixed light area
42 at least a portion.
3rd, bending position
In above-mentioned 2 points of description, part is had been incorporated with for the explanation of bending position；And in fact,
Bending position may be located at the optional position in mixed light area 42.For ease of understanding, below for several possible
Bending position is illustrated：
1) midpoint
As shown in figure 4, bending position can be set to the midpoint in mixed light area 42 so that mixed light area
42 U-shaped symmetrical structures upon bending.
2) impact to border width is reduced as much as possible
As described above, when bent angle alpha is identical, bending position is more remote with the incident side in mixed light area 42,
The height that the mixed light area 42 increases in a first direction is higher；Simultaneously as panel construction 1 is located at leaded light
The top of hardened structure 4, thus when at least a portion in the mixed light area 42 in Fig. 4 is towards light conducting plate structure 4
Bottom bend when, need not consider that mixed light area 42 or light-source structure 3 are made to the light conduction of light guide zone 41
Into blocking or harmful effect.
Therefore, it can the connection for making bending position be positioned as close between mixed light area 42 and light guide zone 41
Place, so that mixed light area 42 is bent as much as possible to 41 bottom of light guide zone, so as to shorten which as much as possible
Length d3 in a second direction ', its frame for display module at respective side edge is reduced or eliminated
The impact of width.
3) avoid just the impact to border width
