  • Patent number: 9348159
    Abstract: An ejection head for ejecting alignment film forming composition includes multiple nozzles. Each nozzle includes a chamber, a composition source, and a control valve. A liquid transportation pipe and a pusher are disposed on the bottom and the top of the chamber, respectively. The pusher is used for pushing the alignment film forming composition out of the liquid transportation pipe. The composition source is used for transporting the alignment film forming composition to the chamber. The control valve is used for controlling switching of the liquid transportation pipe to control output of the alignment film forming composition. Owing to the control valve and the blowing device, the alignment film forming composition is prevented from condensing on the nozzle and blocking the nozzle or from forming large droplets because of accumulation. In this way, the quality of the alignment film is greatly enhanced owing to uniform spraying and regular output.

  • Patent number: 9229258
    Abstract: A to-be-cut liquid crystal mother panel includes a TFT mother substrate forming at least one voltage-applying area onto which an external voltage is applied, a CF mother substrate arranged corresponding to the TFT mother substrate, and a pressure-reduction member located between the CF mother substrate and the TFT mother substrate; the pressure-reduction member corresponds to the voltage-applying area for reducing an adsorptive force between the voltage-applying area and an end portion of the CF mother substrate corresponding to the voltage-applying area. The pressure-reduction member increases the surface roughness of the end portion, avoids a vacuum state formed between the end portion and the voltage-applying area, reduces the adsorptive force between the end portion and the voltage-applying area, and allows the splitting device to separate the end portion from the TFT mother substrate easily after the liquid crystal mother panel is cut.
