Description
Technical field
It the utility model is related to the light alignment technique field of liquid crystal display panel, and in particular to a kind of smooth alignment apparatus.
Background technology
It is backlight liquid crystal display that existing liquid crystal display is most of, and it includes housing, the liquid crystal in housing
Display panel and the backlight module in housing.Usual liquid crystal display panel is by a colored filter substrate (Color
Filter, CF), thin-film transistor array base-plate (Thin Film Transistor Array Substrate, TFT) and fill out
The liquid crystal layer (Liquid Crystal Layer) filled between two substrates is formed, its operation principle be by CF substrates and
Apply driving voltage in TFT substrate to control the rotation of the liquid crystal molecule of liquid crystal layer, the output quantity of light is controlled, by backlight module
Light reflects generation picture.
In the manufacturing process of liquid crystal display panel, it is an important process to carry out orientation to alignment film, that is, passes through orientation
Technique realizes that liquid crystal molecule arranges according to specific direction and angle.There are two kinds of alignment methods in the prior art：Friction matching

Technology, it is radiated at using linearly polarized light through light shield on photosensitive high molecular polymer alignment film, in alignment film surface shape
Alignment microstructure into certain angle of inclination reaches orientation effect.Light orientation has low stain, controllability compared with friction matching
The advantages that high the extensive concern by liquid crystal display manufacturer.In order to judge whether alignment film meets the requirements (such as thickness, voltage
Conservation rate (voltage holding ratio, VHR) etc.), largely to before setting alignment film on the glass substrate opened greatly,
Generally require and first set alignment film to be tested in a small amount on the test substrate of Xiao Zhang, to confirm whether the alignment film conforms to
Ask, if meeting the requirements, alignment film setting is carried out to the glass substrate largely opened greatly according still further to same setting condition.

It is low.
2. operating personnel need manually mark exposure directions (with test glass exposure direction put down to), and glass will be tested manually
Polaroid on glass and light orientation machine aligns one by one.Have that Manual-alignment trueness error is big, cause the precision of orientation angle
Error is big, and aligns one by one, and production efficiency is low.
3. in existing smooth orientation operating process, for various sizes of panel in same test substrate, if often
The alignment direction of individual panel is identical, then can utilize smooth orientation board of the prior art, while in same test substrate
Each panel carries out identical light orientation processing；It is however, different for the alignment direction of different panels in same test substrate
Situation, current light orientation board can not be realized.
