The one first site group 102a of region P and the second site group 102b for being distributed in second area Q.It is known as illustrated in Figure 4 to set
Meter, is usually set to identical by the spacing of two neighbour nodes of all areas, such as wantonly two adjacent net in the group 102a of the first site
The site spacing d1 all sames of point, and site spacing d1 can be equal to the site spacing of wantonly two neighbour node in the group 102b of the second site
D2, however, as optical path length increase makes luminous energy gradually decay, in light path remote position (for example away from the of incidence surface 106
Two region Q) network point distribution density need to be usually improved to meet optical design requirements, therefore the second site of Known designs group 102b
Dot size can be significantly greater than the dot size of the first site group 102a, cause the site of the second site group 102b too intensive
(gap of neighbour node is too small), so when printing net-point, site is readily attached together and produces scumming problem.

State schematic diagram.In this present embodiment, lattice point structure includes the entity shown in the default stipple pattern and Fig. 2 B shown in Fig. 2A
Lattice point structure, entity lattice point structure (Fig. 2 B) include the one first site group 20a for being distributed in first area P and are distributed in the secondth area
The one second site group 20b of domain Q, default stipple pattern (Fig. 2A) include one the 3rd site group 20c that is distributed in first area P and
It is distributed in one the 4th site group 20d of second area Q.Referring first to Fig. 2A, in a default stipple pattern, every two adjacent net
Spacing (such as distance values d2 ' of the distance values d1 ' and second area Q of first area P) all same of point, because with optical path length
Increase luminous energy can gradually decay, thus the dot size in the light path position (i.e. further away from incidence surface 12) farther out can gradually increase with
Meet optical design requirements and preferable briliancy uniformity, the clearance C of two neighbour nodes be provided ' can be towards remote incidence surface direction gradually
Reduce.Therefore, preset stipple pattern first area P and second area Q can pass through the clearance C of every two neighbour node ' size come
Division, the region that a prepsetting gap (such as 0.1mm) is more than when the gap of every two neighbour nodes C ' belong to first area P, and often
The region that the gap of two neighbour nodes is less than the prepsetting gap (such as 0.1mm) belongs to second area Q.As shown in Figure 2 A, Yu Yi
In embodiment, the 3rd site group 20c and the 4th site group 20d of default stipple pattern can be made of multiple circular shaped lattice point T, and
On a reference direction S perpendicular to incidence surface 12, the diameter of multiple circular shaped lattice point T is from the incidence surface 12 of light guide plate 10 to leaded light
Plate 10 relative to a surface 22 of incidence surface 12 direction increase, and on reference direction S any two adjacent circular sites T site
Spacing d1 ', d2 ' (air line distance in two circular shaped lattice point T centers of circle) all same.
Fig. 2 B are refer again to, the entity lattice point structure of one embodiment of the invention, which includes, is distributed in the one first of first area P
The site group 20a and one second site group 20b for being distributed in second area Q, the dot size of the second site group 20b are more than the first net
The dot size of point group 20a, as shown in Figure 2 B, the first site of entity lattice point structure group 20a and the second site group 20b also can be by
Multiple circular shaped lattice point T are formed, and the diameter of multiple circular shaped lattice point T is equally opposite from the incidence surface 12 of light guide plate 10 to light guide plate 10
Increase in the direction on a surface 22 of incidence surface 12, and the site spacing d2 of the second site group 20b is more than the first site group 20a's
Site spacing d1.In this present embodiment, the 3rd site group 20c and entity of the default stipple pattern of first area P are similarly positioned in
The network point distribution of the first site group 20a of lattice point structure is identical, but is similarly positioned in the 4th of the default stipple pattern of second area Q the
Site group 20d is different from the network point distribution of the second site group 20b of entity lattice point structure, as follows with both Fig. 3 A and Fig. 3 B explanations
In the different network point distribution modes of second area Q.The second area Q of bottom surface of light guide plate 14, which can be drawn, is divided into multiple unit areas, figure
3A shows network point distribution kenels of the 4th site group 20d of default stipple pattern under unit area, and Fig. 3 B show entity site
Network point distribution kenels of the second site group 20b of structure under unit area.Compare Fig. 3 A and Fig. 3 B to understand, in the present embodiment
In, an area ratio and fourth site of the dot area with the unit area M gross areas in the group's 20b unit areas M of the second site
Dot areas of the group 20d in unit area M is identical with an area ratio of the unit area M gross areas, that is, the second site group
20b has identical unit area distribution density, but nets of the second site group 20b in unit area M with the 4th site group 20d
Point spacing d2 is more than the site spacing d2 ' of the 4th site group 20d, and the dot size of the second site group 20b is more than unit area M
The dot size of interior the 4th site group 20d.According to the design of the embodiment of the present invention, for example, when site, group 20b, 20d are
When circular shaped lattice point T is formed, the average circular shaped lattice point diameter (can be 1.1962mm) of the second site group 20b of entity lattice point structure
More than the average circular shaped lattice point diameter (can be 1.1857mm) of the 4th site group 20d of default stipple pattern, the second site group 20b
Site spacing d2 (can be 1.3362mm) be more than the site spacing d2 ' (can be 1.2557mm) of the 4th site group 20d, and second
Site group 20b in two neighbour nodes produce clearance C for 0.14mm (>0.1mm).Therefore, in this present embodiment, it is distributed in second
Although the second site larger (1.1962mm of group's 20b sizes of region Q>1.1857mm), but can be by increasing site spacing d2
(1.3362mm>The effect that clearance C is more than 0.1mm 1.2557mm) is obtained, therefore can be kept away in the case where maintaining identical network point distribution density
Scumming situation is produced from second area Q.
According to the design of above-mentioned each embodiment, first by the default stipple pattern of design one, make the region (example that light path is different
Such as first area P, second area Q) produce respective network point distribution density reference value, with meet optical design requirements and provide compared with
Good briliancy uniformity, can be according to the default respective site of stipple pattern different zones so when forming entity lattice point structure
Distribution density reference value, under the premise of the network point distribution density identical with default stipple pattern is maintained and meanwhile increase dot size and
Site spacing, so when net-point printing, can avoid site from linking together without producing scumming situation.
The foregoing is merely illustrative of the preferred embodiments of the present invention, it is impossible to the scope implemented of the present invention is limited with this, it is all according to
The simple equivalent changes and modifications that the claims in the present invention and the content of the invention are made, all still belongs to the scope that patent of the present invention covers
It is interior.In addition of the invention any embodiment or claim be not necessary to reach disclosed herein whole purposes or advantage or spy
