The similar unit of structure is to be given the same reference numerals in the figure.
Fig. 1 please be please refer to, Fig. 1 is the knot of the preferred embodiment of the light alignment apparatus for liquid crystal display panel of the invention
Structure schematic diagram.The light alignment apparatus 11 is used to carry out liquid crystal display panel 12 light orientation processing, the liquid crystal display panel 12 packet
Include the display area 121 being made of pixel unit, the liner for applying orientation voltage to the pixel unit of display area 121
122 and for connect liner 122 and display area 121 pixel unit signal wire 123.
The light alignment apparatus 11 includes that voltage generates power supply 111 and probe 112.Voltage generates power supply 111 for providing
Orientation total voltage；It is preferably constant voltage source that the voltage, which generates power supply 111,；The liner of liquid crystal display panel 12 is arranged in probe 112
On 122, power supply 111 is generated with voltage by connecting line 113 and is connect, for being mentioned to the display area of liquid crystal display panel 12 121
For orientation voltage；Wherein adjustable resistance 114 is provided on connecting line 113.
The light alignment apparatus 11 for liquid crystal display panel 12 of this preferred embodiment in use, determine liquid crystal display first
The orientation voltage of the display area 121 of panel 12 can specifically determine the orientation voltage of display area by following formula:
