The pre-tilt angle of work is designed, specifically, and the liquid crystal molecule 51 of PSVA liquid crystal panels is intended to reach a pre-tilt angle, then needs to make correspondence
Top electrode pattern 1211 and bottom electrode pattern 221 between have voltage difference corresponding with the pre-tilt angle, namely need correspondence
Top electrode pattern 1211 on apply corresponding virtual voltage, the size of corresponding branch 1222 needs satisfaction to be applied to conducting parts
Voltage on 122 trunk 1221 after the partial pressure of branch 1222 higher level's electrode pattern 1211 reach the corresponding actual electricity
Pressure.
For example, in actual production, the pre-tilt angle of the liquid crystal molecule 51 of 32 " PSVA liquid crystal panels should be more than 65 "
The pre-tilt angle of the liquid crystal molecule 51 of PSVA liquid crystal panels, namely the correspondingly upper electricity of 32 " PSVA liquid crystal panels when carrying out orientation
Virtual voltage in pole figure case 1211 should be more than the actual electricity on the Top electrode pattern 1211 of the PSVA liquid crystal panels of correspondence 65 "
Pressure, therefore design electrode group 121 includes the row correspondence of Top electrode pattern 1211 and one of the PSVA liquid crystal panels of a row correspondence 32 "
The Top electrode pattern 1211 of 65 " PSVA liquid crystal panels, while designing the length of the branch 1222 of the PSVA liquid crystal panels of correspondence 32 "
Degree is less than point of the length of the branch 1222 of the PSVA liquid crystal panels of correspondence 65 " or the PSVA liquid crystal panels of design correspondence 32 "
The width of branch 1222 is more than the width of the branch 1222 of the PSVA liquid crystal panels of correspondence 65 " or the PSVA liquid of design correspondence 32 "
The length of the branch 1222 of crystal panel is less than the Design of length of the branch 1222 of the PSVA liquid crystal panels of correspondence 65 " and correspondence 32 "
PSVA liquid crystal panels branch 1222 width be more than correspondence 65 " PSVA liquid crystal panels branch 1222 width so that
The resistance of the branch 1222 of the PSVA liquid crystal panels of correspondence 32 " is less than the electricity of the branch 1222 of the PSVA liquid crystal panels of correspondence 65 "
Resistance, so that after voltage is applied to the trunk 1221 of conducting parts 122, the Top electrode pattern of the PSVA liquid crystal panels of correspondence 32 "
Virtual voltage on 1211 is more than the virtual voltage on the Top electrode pattern 1211 of the PSVA liquid crystal panels of correspondence 65 ", and reaching makes
The pre-tilt angle of the liquid crystal molecule 51 of 32 " PSVA liquid crystal panels is more than the pre-dumping of the liquid crystal molecule 51 of 65 " PSVA liquid crystal panels
The purpose at angle.
