Embodiment
Followingly several embodiments of the invention be will enumerate, and appended graphic, element numbers etc., the effect that describes constitution content of the present invention in detail and will reach coordinated.
Please refer to Fig. 2 and Fig. 3, Fig. 2 is the structural representation that spacer of the present invention is arranged at display panels.Fig. 3 is the end view drawing that spacer of the present invention is arranged at LCD sheet frame glue.The structure of the display panels 70 of the present embodiment, comprise a upper substrate (can be colored filter substrate) 40, be parallel to described upper substrate 40 an infrabasal plate (can be thin film transistor base plate) 50, be arranged at the liquid crystal layer (not shown) between described upper substrate 40 and described infrabasal plate 50.Display panels 70 comprises perform region 70A and frame glue zone 70B, and frame glue zone 70B is provided with frame glue 64, is used for bonding upper substrate 40 and infrabasal plate 50.Liquid crystal layer is sealed in the space that upper substrate 40, infrabasal plate 50 and frame glue 64 surrounds.Display panels 70 also comprises a plurality of the first spacers 62 that are positioned at described frame glue zone 70B and conducting particles 63, a plurality of the second spacer 61 that is positioned at described perform region 70A.
Described the first spacer 62 is arranged at a frame glue zone 70B of display panels 70 peripheries, be used for supporting described upper substrate 40 and described infrabasal plate 50, conducting particles 63 is arranged in the frame glue 64 of frame glue zone 70B of display panels 70, connect described two substrates 40 in order to conduction, 50(is the public electrode of conducting upper substrate 40 and infrabasal plate 50).The space that described frame glue 64 is filled between described the first spacer 62 and described conducting particles 63, and seal described two substrates 40,50.Described the second spacer 61 is arranged at a perform region 70A of display panels 70 inside on liquid crystal panel, is used for supporting and keeping the box of display panels 70 thick.
In an embodiment, described display panels 70 is that (namely the frame glue zone 70B around the periphery of whole display panels 70 is evenly distributed with conducting particles 63 to an all-round conduction type display panels, described two substrates 40,50 by conducting particles 63 conductings around whole one week of panel), described conducting particles 63 can be a conductive gold spacer (Au Ball).
In an embodiment, based on the consideration of process convenience, the first spacer 62 and the second spacer 61 should use photosensitive material, can utilize whereby exposure and the mode of developing to form a kind of column photoresistance spacer, and size and setting position that can more accurate control gap 61,62.Because the propping material of two spacers 61,62 is the same, can allow the perform region 70A of display panels 70 and the gap of frame glue zone 70B keep consistency better.Described the first spacer 62 and the second spacer 61 are column photoresistance spacer.
As above background technology is addressed, when the first spacer 62 that is arranged at display panels 70 external surrounding frame glue zone 70B is a kind of photoresistance spacer of traditional column, in distribution, conducting particles 63 is set and produces stacking phenomenon with the first spacer 62 that is arranged at equally display panels 70 external frame glue zone 70B, and destroyed the box gap of display panels 70.
Please refer to Fig. 4, Fig. 4 is the vertical view according to the described spacer of the embodiment of the present invention.In an embodiment, the first spacer 62 is a polygon-shaped column structure, comprises a through hole 621 that is arranged at central position and the outer wall 82 that surrounds described through hole 621.Thus, when conducting particles 63 and the first spacer 62 produce stacking the time, it is vertical corresponding the first spacer 62 of conducting particles 63, conducting particles 63 can be embedded into through hole 621 inside, and can not affect the size in display panels 70 gaps, do not affect the performance that conducts of upper substrate 40 and infrabasal plate 50 simultaneously yet.
As shown in Figure 4, described through hole 621 has internal diameter 80, according to an embodiment, and consider that present technology is with compatible, through hole 621 is a regular polygon, and its internal diameter is at least greater than 7 microns (um), and the thickness of outer wall 82 can be according to the different width of elasticity capacity design of different materials.The internal diameter 80 of through hole 621 can be when light shield (Mask) designs, and the position of internal diameter 80 correspondences is covered up, and light is sheltered from, and the position of outer wall 82 correspondences is spilt, allow illumination arrive in exposure, accordingly, just can produce the first spacer 62 with through hole 621.
It should be noted that, the first spacer 62 also can have identical structural design with the second spacer 61, but because the first spacer 62 is the internal work zone 70A that are arranged at display panels 70, and conducting particles 63 and the stacking situation of the first spacer 62 can not occur.
