Embodiment
[first embodiment]
Fig. 2 is the diagrammatic cross-section according to the display panels of the present invention's first preferred embodiment.Please refer to Fig. 2, the display panels 200 of present embodiment comprises a colored optical filtering substrates 2100, a subtend substrate 2200, a liquid crystal layer 2300 and a glue frame 2400.Wherein, glue frame 2400 and liquid crystal layer 2300 are disposed between colored optical filtering substrates 2100 and the subtend substrate 2300, and glue frame 2400 is around liquid crystal layer 2300.In addition, colored optical filtering substrates 2100 has a plurality of thrusts 2140 and uses electrode layer 2150 with having altogether of these thrusts 2140 of covering, and colored optical filtering substrates 2100 electrically connects with subtend substrate 2200 via the common electrode layer 2150 of these thrust 2140 tops, and these thrusts 2140 can be so that keep a bug hole spacing between colored optical filtering substrates 2100 and the subtend substrate 2200.
More specifically, colored optical filtering substrates 2100 also comprises a substrate 2110, one black matrix layer 2120, a chromatic filter layer 2130 and an alignment film 2160, and wherein black matrix layer 2120 is disposed on the substrate 2110.In addition, chromatic filter layer 2130 is disposed on the substrate 2110, and matrix layer 2120 is deceived in the cover part at least.Common electrode layer 2140 is disposed on the substrate 2110, and covering should black matrix layer 2120 and chromatic filter layer 2130.In addition, alignment film 2160 is disposed on the common electrode layer 2140.
In the present embodiment, thrust 2140 is made of with chromatic filter layer 2130 black matrix layer 2120, and common electrode layer 2140 covers thrust 2140.It should be noted that thrust 2140 also can only be made of black matrix layer 2120 or chromatic filter layer 2130.In addition, alignment film 2160 does not cover the common electrode layer 2140 of thrust 2140 tops.
Subtend substrate 2200 comprises a substrate 2210, a thin film transistor (TFT) array 2220, a protective seam 2230, a plurality of pixel electrode 2240, a plurality of connection pad 2240a and an alignment film 2250; wherein thin film transistor (TFT) array 2220 is disposed on the substrate 2110, and protective seam 2230 cover film transistor arrays 2220.In addition, protective seam 2230 has a plurality of contact hole 2230a, and it exposes part thin film transistor (TFT) array 2220.These pixel electrodes 2240 are disposed on the protective seam 2230, and electrically connect with thin film transistor (TFT) array 2220.In addition, these connection pads 2240a is disposed on the protective seam 2230, and the common electrode layer 2150 of thrust 2140 tops contacts with connection pad 2240a.Moreover alignment film 2250 covers pixel electrode 2240.The material of connection pad 2240a for example be indium tin oxide (indium tin oxide, ITO), indium-zinc oxide (indium zinc oxide, IZO), Zinc-aluminium (aluminum zinc oxide, AZO) or other transparent conductor materials.
Because the common electrode layer 2150 of thrust 2140 tops contacts with connection pad 2240a, so the common voltage exported of the chip for driving on the subtend substrate 2200 can input to the common electrode layer 2150 of thrust 2140 tops in regular turn via these connection pads 2240a.In other words, compared to prior art, thrust that present embodiment adopts 2140 is made of the part rete that constitutes colored optical filtering substrates 2100, so present embodiment need not increase extra processing procedure or equipment just can form thrust 2140.
In the present embodiment, subtend substrate 2200 has thin film transistor (TFT) array 2220, yet thin film transistor (TFT) array 2220 also can be integrated on the colored optical filtering substrates 2100 COA (Color Filter On Array) substrate just.In addition, in order to improve the differ phenomenon of (Gap mura) of peripheral bug hole spacing, thrust 2140 also can have other design, its describe in detail as after.
[second embodiment]
Fig. 3 A is the vertical view according to the thrust of the present invention's second preferred embodiment, and Fig. 3 B illustrates along the sectional view of the A-A ' line among Fig. 3 A, and Fig. 3 C illustrates along the sectional view of the B-B ' line among Fig. 3 A.Please also refer to Fig. 3 A, 3B and 3C, the thrust 3140 of present embodiment comprises black matrix layer 2120 and chromatic filter layer 2130, and wherein chromatic filter layer 2130 comprises ruddiness filter layer 2130a, green glow filter layer 2130b and blue light filter layer 2130c.In addition, ruddiness filter layer 2130a is disposed on the black matrix layer 2120, and green glow filter layer 2130b is disposed between ruddiness filter layer 2130a and the blue light filter layer 2130c.
It should be noted that for fear of blue light filter layer 2130c generation and peel off that the top of each thrust 3140 in each zone is for being connected with each other, just the blue light filter layer 2130c of each thrust 3140 in each zone is for being connected with each other.Yet ruddiness filter layer 2130a, the green glow filter layer 2130b of each thrust 3140 and the stacking order of blue light filter layer 2130c do not limit shown in Fig. 3 B or 3C, just are not defined as blue light filter layer 2130c for being connected with each other.In other words, the chromatic filter layer 2130 of each thrust 3140 is for being connected with each other.In addition, the top of each thrust 3140 for example is circular, square, rectangle or other shapes.In addition, the continuous mode at the top of each thrust 3140 is not defined as shown in Fig. 3 A yet, its describe in detail as after.
Fig. 3 D to Fig. 3 F is the vertical view according to the thrust of the present invention's the 3rd preferred embodiment.Please refer to Fig. 3 D, the top of each thrust 3140 can be to connect into the H type.Please refer to Fig. 3 E, the top of each thrust 3140 can be to connect into the E type.Please refer to Fig. 3 F, the top of each thrust 3140 can be to connect into the S type.
In sum, the present invention utilizes the black matrix layer that constitutes colored optical filtering substrates or chromatic filter layer and forms thrust, so colored optical filtering substrates and subtend substrate can be electrical connected by thrust.When the subtend substrate was thin-film transistor array base-plate, the voltage that the chip for driving on the subtend substrate is exported can conduct on the colored optical filtering substrates via the common electrode layer on these thrusts.
In addition, adopt conducting resinl and conducting resinl coating apparatus compared to prior art, the present invention can improve the yield of display panels, and the quantity of required process apparatus also can reduce, and the cost of letter province conducting resinl and the cost of equipment.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, any those of ordinary skills, without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is when with being as the criterion that claim was defined.
