Width be L0;And as shown in figure 11, it is assumed that the width for adding sealant after bed course becomes L ', and sealant is Chong Die with black matrix
Partial width is L0’。
Since volume, length that bed course increases front and back sealant will not change, then cross-sectional area S is also constant, because
This is available:
Before bed course increase, S=(L-L0)×(T0+T1)+L0×T1..........................(1)
After bed course increase, S=(L '-L0′)×(T0+T1-T2)+L0′×T1..................(2)
It can be calculated according to formula 1 and formula 2:
L′T0+L′T1-L0′T0-(L′-L0′)T2=LT0+LT1-L0T0....................(3)
Again due to (L '-L0′)T2>=0, therefore L ' T0+L′T1-L0′T0≥LT0+LT1-L0T0, obtain L '-L < L '0-L0, can
To show after adding bed course, the sealant in the region between black matrix and display area broadens.
Assuming that the distance that sealant extends to the left is x after increasing bed course1, the distance extended to the right is x2, then:
x1=(L '-L0′)-(L-L0)..........................(4)
x2=L0′-L0.....................(5)
A separately is set as spreading coefficient, then has x2=ax1..............(6)
It can be calculated according to formula 4, formula 5 and formula 6:
aL′-(a+1)L′0=aL- (a+1) L0...............(7)
After adding bed course, the increased area in area=right side of left side reduction is available:
T2(L-L0)=x1(T0+T1-T2)+x2T1........................................(8)
It can be calculated according to formula 4, formula 5 and formula 8:
[T0+(a+1)T1-T2]×(L′-L0')=[T0+(a+1)T1]×(L-L0)......(9)
It can be calculated according to formula 7 and formula 9:
It can be derived from according to formula 3, formula 10 and formula 11:
A=1;
