Describe the technical characterictic of display panel of the present invention and frame narrowing thereof, edge strength enhancing method in detail below with reference to accompanying drawing.
The frame narrowing method of display panel of the present invention is described below.With reference to Fig. 1, it illustrates the top view of display panel 10, and comprising three first sides 11, another second side 12 then can be used for circuit in the panel is connected to the external circuit board (figure does not show), and three first sides 11 are connected each other with second side 12.Be equipped with shading region 13 near first side 11,12 places, second side, the shading region material is for example with black matrix (Black Matrix) same material or can form simultaneously with black matrix.Frame narrowing of the present invention is mainly used in narrowing of first side 11, below is that example describes with first side 11 promptly.
Fig. 2 illustrates among Fig. 1 along the cut-open view of 1-1 profile line, and display panel 10 comprises first substrate 21, second substrate 22 and frame glue 23 (liquid crystal limitation structure).In the present embodiment, first substrate 21 can be the colored filter matrix base plate, second substrate 22 can be film transistor matrix substrate, perhaps first substrate 21 can be film transistor matrix substrate, second substrate 22 can be the colored filter matrix base plate, and shading region 13 is formed at first substrate, 21 belows that comprise the colored filter matrix, and its position is rough corresponding to frame glue 23.Frame glue 23 is configured between this first substrate 21 and second substrate 22, and 13 of shading regions are configured between the frame glue 23 and first substrate 21, and its width represents that with w w ' then is a border width.
With reference to Fig. 3, display panel 10 is tilted, make first substrate 21 and grinding component 31 folders first of lapping device 30 grind angle θ 1, this first grinding angle θ 1 is an acute angle.Inclination herein is meant that display panel 10 tilts with respect to the grinding component 31 of lapping device 30, and the historical facts or anecdotes border can refer to tilt display panel 10.Grind under the situation of angle θ 1 in display panel 10 inclinations first, utilize 31 pairs first substrates 21 of grinding component of this lapping device 30 to grind, and further grind shading region 13, and on first substrate 21, grind out first face off 26.In one embodiment, first scope of grinding angle θ 1 is between between about 70 degree and about 88 degree, or preferably between about 78 degree and about 85 are spent.Treat the residue width w of shading region 21 " scope between about 0.35 millimeter and about 1 millimeter the time, stop the grinding of 30 pairs first substrates of this lapping device 21 and shading region 13.After the grinding, originally border width w ' is compared to shading region width w " part that has more is worn away, so the time border width w ' equal shading region width w ", promptly the scope of border width w ' is also between about 0.35 millimeter and about 1 millimeter.Between 0.1 micron and 0.88 micron, full roughness height Ry is approximately between 0.93 micron and 8.5 microns approximately for the center line average roughness Ra of first face off 26 after the grinding.
In one embodiment, grind under the situation of angle θ 1 in display panel 10 inclinations first, utilize this lapping device 30 to continue the frame glue 23 and second substrate 22 are ground, final situation about forming as shown in Figure 4, wherein the edge of first substrate 21, shading region 13, frame glue 23 and second substrate 22 trims into copline approximately.
With reference to Fig. 5, according to another embodiment, after grinding first substrate 21, then display panel 10 is tilted towards opposite side, make second substrate 22 and lapping device 30 folders second grind angle θ 2.Inclination herein is meant that display panel 10 tilts with respect to the grinding component 32 of lapping device 30, and the historical facts or anecdotes border can refer to tilt display panel 10.Grind under the situation of angle θ 2 in display panel 10 inclinations second, utilize 32 pairs second substrates 22 of second grinding component of this lapping device 30 to grind, and on second substrate 22, grind out second face off 28, as shown in Figure 6.This moment, border width w ' equaled shading region width w ".Second scope of grinding angle θ 2 can be between between about 70 degree and about 88 degree, or preferably between about 78 degree and about 85 are spent.Structure situation as shown in Figure 6 after second substrate 22 grinds, between 0.1 micron and 0.88 micron, full roughness height Ry is approximately between 0.93 micron and 8.5 microns approximately for the center line average roughness Ra of second face off 28 after the grinding.
In detail, in the present embodiment, lapping device 30 can comprise that first grinding component 31 and second grinding component, 32, the first grinding components 31 are in order to grind 32 of first substrate 21 and this shading region 13 or frame glue 23, the second grinding components in order to grind second substrate 22 or frame glue 23.Thus, because of first grinding component 31 can adopt different settings with second grinding component 32, the flexible application when being fit to make; But it is not the restriction in the application.In actual applications, also can adopt same grinding component to grind applied in any combination on first substrate 21, second substrate 22, shading region 13 and frame glue 23 or other elasticity.
Fig. 6 shows that it is ideal state that the both sides equal portions grind, and in the practical application, also may not utilize equal portions are ground, as shown in Figures 7 and 8.
With reference to Fig. 7, grind under the situation that time is long or amount of grinding is more that angle θ 1 grinds with first, this lapping device 30 can grind this frame glue 23 and the subregion of this second substrate 22, makes the face off 26 of winning for extend to the part zone of second substrate 22 in regular turn through shading region 13, frame glue 23 from first substrate 21.Then relatively weak point or amount of grinding are less relatively with second time of grinding angle θ 2 grindings, and therefore second face off 28 only comprises another part zone of second substrate 22.Relatively, also have the situation of similar Fig. 8, it is short or amount of grinding is less wherein to grind time that angle θ 1 grinds with first, and it is long or amount of grinding is more to grind time that angle θ 2 grinds with second.Therefore, first face off 26 only comprises the part zone of first substrate 21.28 another part zones that extend to first substrate 21 from second substrate 22 in regular turn through shading region 13, frame glue 23 of second face off.
