Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
The backboard of liquid crystal indicator of the present invention is described below.
Backboard has different zones;
Each zone has corresponding flatness;
The forward deviation value of flatness in zone that is arranged in four jiaos of backboards is maximum in each zone;
The absolute value of negative sense deviation value of flatness that is arranged in the zone in the middle of the backboard is maximum in each zone;
The difference of the zone that is positioned at four jiaos of backboards and the forward deviation value of the flatness that is positioned at the zone in the middle of the backboard is smaller or equal to first preset value;
The difference that is positioned at zone and the absolute value of the negative sense deviation value of the flatness in the zone that is positioned at four jiaos of backboards in the middle of the backboard is smaller or equal to second preset value;
Be positioned at four jiaos of backboards the zone flatness forward deviation value and the negative sense deviation value of the flatness that is positioned at the zone in the middle of the backboard absolute value and smaller or equal to the 3rd preset value.
Be arranged in forward deviation value maximum expression in each zone of flatness in the zone of four jiaos of backboards: the forward deviation value of flatness in zone that is positioned at four jiaos of backboards is more than or equal to the forward deviation value of other regional flatnesses of backboard.
The absolute value of negative sense deviation value of flatness that is arranged in the zone in the middle of the backboard is in the maximum expression in each zone: the absolute value of negative sense deviation value of flatness that is positioned at the zone in the middle of the backboard is more than or equal to the absolute value of the negative sense deviation value of other regional flatnesses of backboard.
Referring to Fig. 1, be the synoptic diagram of the embodiment of the backboard of liquid crystal indicator of the present invention.
In this embodiment, the zone that is positioned at four jiaos of backboards is an angular zone, is respectively first angular zone, second angular zone, and the Delta Region, the 4th angular zone is expressed as F1, F2, F3, F4.
Being positioned at the middle zone of backboard is zone line, is expressed as C.
The forward deviation value of the flatness of angular zone is maximum in each zone.The absolute value of the negative sense deviation value of the flatness of zone line is maximum in each zone.
The forward deviation value of the flatness of angular zone and zone line poor, the absolute value of the negative sense deviation value of the flatness of zone line and angular zone poor, and maximum forward deviation value and maximum negative to the absolute value of deviation value with, be limited in the scope of regulation.Thereby, the flatness of backboard is arranged in certain scope.This restricted portion is the scope that is provided with in advance.
So, low, four jiaos of high backboards in the middle of having formed on the whole.Making that backboard and LGP are smooth contacts, and avoids the generation of image quality bad phenomenon such as bright line and light leak on the module backlight.
In a more excellent embodiment, between 0 to 0.2 millimeter, promptly first preset value is 0.2 millimeter in the difference of the forward deviation value of the flatness in the zone of four jiaos of backboards and the zone in the middle of backboard.
As shown in Figure 1, the difference of the forward deviation value of the forward deviation value of the flatness of angular zone and the flatness of zone line is not more than 0.2 millimeter.
So, the gap of the forward deviation value of the flatness of pilot angle zone and zone line is in 0.2 millimeter scope.
In a more excellent embodiment, the zone in the middle of backboard and in the difference of the absolute value of the negative sense deviation value of the flatness in the zone of four jiaos of backboards between 0 to 0.2 millimeter, promptly second preset value is 0.2 millimeter.
As shown in Figure 1, the difference of the absolute value of the negative sense deviation value of the flatness of zone line and angular zone is not more than 0.2 millimeter.
So, the gap of the absolute value of the negative sense deviation value of the flatness of control zone line and angular zone is in 0.2 millimeter scope.
This 0.2 millimeter preferred value for obtaining through experiment test; Controlling four jiaos exceeds in 0.2 millimeter scope than the centre; Can make when guaranteeing to avoid the generation of image quality bad phenomenon such as bright line and light leak on the module backlight, can not make mould too accurate again, practice thrift cost.
In a preferred implementation, the absolute value of the negative sense deviation value of the flatness in the forward deviation value of the flatness in the zone of four jiaos of backboards and the zone in the middle of backboard and be the value between 0 to 1 millimeter, promptly the 3rd preset value is 1 millimeter.So, the whole flatness of backboard is limited in 1 millimeter.
This 1 millimeter preferred value for obtaining through experiment test is for using the threshold value that the present invention guarantees the picture good quality.It is thus clear that employing the present invention to the requirement reduction of the whole flatness of backboard, has practiced thrift cost.
In a preferred implementation; Negative sense irrelevance in the negative sense irrelevance in zone in the middle of backboard and the zone between the zone of four jiaos of the backboards zone middle with being positioned at backboard is identical, and the forward irrelevance is identical with the forward irrelevance in the zone that is positioned at four jiaos of backboards.
As shown in Figure 1, be interval region in zone in the middle of backboard and the zone between the zone of four jiaos of backboards, be expressed as D.This interval region is used for from middle zone to the angular zone transition between angular zone and zone line, and therefore, the negative sense irrelevance of interval region is identical with the negative sense irrelevance of zone line, and the forward irrelevance is identical with the forward irrelevance of angular zone.So, it is better to make that LGP contacts with backboard.
In a preferred implementation, identical in the flatness in the flatness in the zone between two jiaos on the backboard minor face zone middle with being positioned at backboard.
As shown in Figure 1, backboard is a rectangle, and first angular zone and second angular zone are positioned at a side minor face of backboard, is two gap areas between first angular zone and second angular zone, is expressed as A7 and A8 respectively.Delta Region and the 4th angular zone are positioned at the opposite side minor face of backboard, are two gap areas between Delta Region and the 4th angular zone, are expressed as A5 and A6 respectively.
The flatness of gap area is identical with zone line, matches with angular zone, and is low in the middle of so forming in the part, and the state that both sides are high further improves LGP and contacts raising picture display quality with backboard is seen.
Embodiment
The embodiment of the invention is as shown in Figure 2.In the present embodiment, zone line comprising 5 measurement points, is expressed as C1～C5; Be positioned at the angular zone of four jiaos of backboards, be expressed as F1～F4; Interval region between zone line and angular zone is two, and first interval region comprising 9 test points, is expressed as D1～D9, and second interval region comprising 9 test points, is expressed as D10～D18.Be positioned at the gap area between two jiaos of same minor face of backboard, be expressed as A5～A8 respectively.In addition, gap area also is positioned between a long limit of zone line and backboard, becomes T shape, is expressed as A1～A4 respectively.Both sides at the vertical line of T shape have elevated regions, are expressed as B1 and B2.Fig. 2 bend zone is for being used for the supporting zone of supporting back board in the test.
With test point D1 is that benchmark is measured.
The flatness of gap area A1～A8 is+0/-0.8mm;
