Detailed description of the invention
Following will enumerate several embodiments of the invention, and coordinate institute accompanying drawings, element numbers etc., describe the constitution content of the present invention and effect to be reached in detail.
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, the infrabasal plate (can be thin film transistor base plate) 50 including a upper substrate (can be colored filter substrate) 40, being parallel to described upper substrate 40, the liquid crystal layer (not shown) being arranged between described upper substrate 40 and described infrabasal plate 50.Display panels 70 includes that working region 70A and frame glue region 70B, frame glue region 70B are 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 are surrounded.Display panels 70 also includes multiple the first spacer 62 being positioned at described frame glue region 70B and conducting particles 63, multiple the second spacer 61 being positioned at described working region 70A.
Described first spacer 62 is arranged at a frame glue region 70B of display panels 70 periphery, for supporting described upper substrate 40 and described infrabasal plate 50, conducting particles 63 is arranged in the frame glue 64 of frame glue region 70B of display panels 70, in order to be conductively connected described two substrates 40,50(i.e. turns on the public electrode of upper substrate 40 and infrabasal plate 50).The space between described first spacer 62 and described conducting particles 63 filled by described frame glue 64, and seals described two substrates 40,50.Described second spacer 61 is arranged at the working region 70A on liquid crystal panel within display panels 70, for supporting and keep the box thickness of display panels 70.
In an embodiment, described display panels 70 is that (i.e. the peripheral frame glue region 70B around 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 turning on around the whole panel conducting particles of a week 63), described conducting particles 63 can be a conductive gold spacer (Au Ball).
In an embodiment, consideration based on process convenience, the first spacer 62 and the second spacer 61 preferably use sensitive material, available whereby exposure to form a kind of column photoresistance spacer with the mode of development, and can more accurately control spacer 61, the size of 62 with position is set.Owing to the backing material of two spacers 61,62 is the same, can allow display panels 70 working region 70A and frame glue region 70B gap keep concordance preferable.Described first spacer 62 and the second spacer 61 are column photoresistance spacer.
As above background technology is addressed, when the photoresistance spacer that the first spacer 62 being arranged at display panels 70 external surrounding frame glue region 70B is a kind of tradition column, conducting particles 63 is set in distribution and may produce, with the first spacer 62 being similarly provided at display panels 70 external frame glue region 70B, the phenomenon stacked, and destroy the box gap of display panels 70.
Refer to the top view that Fig. 4, Fig. 4 are the most described spacers.In an embodiment, the first spacer 62 is a polygon-shaped column structure, including being arranged at a through hole 621 of central position and surrounding the outer wall 82 of described through hole 621.Thus, when conducting particles 63 and the first spacer 62 produce stacking when, i.e. the most corresponding first spacer 62 of conducting particles 63, it is internal that conducting particles 63 can be embedded into through hole 621, without affecting the size in display panels 70 gap, nor affect on upper substrate 40 and infrabasal plate 50 conducts performance simultaneously.
As shown in Figure 4, described through hole 621 has internal diameter 80, according to an embodiment, and consider that current Technology is with compatible, through hole 621 is a regular polygon, and its internal diameter can design different width according to the elasticity capacity of different materials at least above 7 microns (um), the thickness of outer wall 82.The position of internal diameter 80 correspondence can be covered up when light shield (Mask) designs, sheltered from by light by the internal diameter 80 of through hole 621, and the position of outer wall 82 correspondence is spilt, allow light shine exposure when, accordingly, just can produce first spacer 62 with through hole 621.
It should be noted that, first spacer 62 also can have identical structure design with the second spacer 61, but because the first spacer 62 is disposed on the inside work areas 70A of display panels 70, without there is conducting particles 63 and the situation of the first spacer 62 stacking.
