Step S322, obtains the original position and end position of the pending through hole.
The original position of the pending through hole refers to the through hole near the lead to the hole site of adjacent left side grating, and this is pending
The end position of through hole refers to the through hole near the lead to the hole site of adjacent the right grating.
Fig. 5 is referred to, the starting position coordinates of the pending through hole are (xge, zge), the stop bits of the pending through hole
Coordinate is put for (xgs, zgs).
As shown in fig. 5, it is assumed that coordinate system with the starting position of display screen matrix as (0,0) origin, then the 1st picture of display screen
Plain starting position coordinates for (0,0), then n-th p pixel starting position coordinates of display screen be (xps, zps=0), wherein, xps

Assume that the grating has certain light angle of divergence, and the light angle of divergence of the grating is θ.
(1) when θ s≤θ and θ e≤θ is met simultaneously：
Due toTherefore xa can be calculated according to following formula (1)：
In the same manner, xb can be calculated according to following formula (1) or formula (2)：
(2) if θ is s >=θ and θ e >=θ, it is not required to calculate effect of this light hole to (xs, zs), i.e., no longer calculates the thang-kng
The number of odd even pixel in hole, into the judgement flow process of next light hole；
(3) as a kind of specific embodiment, if the light angle of divergence of the grating is located at first angle and described the
Between two angles, according to first angle, the smooth angle of divergence and the original position, the first joining position is calculated
Put；According to second angle, the smooth angle of divergence and the end position, the second joining position is calculated.
Fig. 8 is referred to, as a kind of embodiment, it is assumed that the light angle of divergence is θ, if θ is s≤θ ＜ θ e, with the straight line of θ angles

Xb=xs+zs × tg θ
Fig. 9 is referred to, as another embodiment, if θ s are ＞ θ >=θ e, with the straight line of θ angles and the intersection point of grating
(xgm, zgm), needs due to zgm=zgs=zge=-distGL therefore only to calculate as the pending light hole original position
The value of xgm：
Xgm=xs-tg θ (zs-zgm)
The now abscissa xb coordinates of the second joining position constant (according to formula (2) or formula (3) calculating), but first
The abscissa xa coordinates of joining position should be point (xs, zs) and (xgm, zgm) line and the intersection point abscissa of display screen, be somebody's turn to do
Abscissa can be obtained with geometrical relationship：
Xa=xs-zs × tg θ
