The invention provides a manufacturing method of a blue-phase liquid crystal array substrate. The manufacturing method comprises the following steps that step one, a grid line, a common electrode wire and a temperature control line are formed on a glass substrate; step two, a first gate insulation layer and a semiconductor layer are formed; step three, a data line, a source electrode and a drain electrode are formed; step four, a drain electrode contact hole and multiple common electrode line contact holes are formed; step five, a second insulation layer, a pixel electrode and a common electrode are formed; step six, first temperature control material contact holes and a second temperature control material contact holes are formed; step seven, a temperature control material zone is formed. The temperature control line and the temperature control material zone are made, and an electric signal is input for the temperature control line during UV irradiation, so that voltage difference forms between the temperature control line and the common electrode line to produce current, the heat produced by a high-resistance temperature control material is effectively conducted to a liquid crystal layer, the temperature uniformity is ensured, blue-phase liquid crystal can be kept stable, and the product yield is improved. In addition, due to the fact that the temperature control material is directly integrated to the liquid crystal substrate, additional temperature control devices are not needed, and the costs can be saved.
Description
technical field [0001] The invention belongs to the technical field of blue-phase liquid crystal display, and in particular relates to a manufacturing method of a blue-phase liquid crystal array substrate. [0002] technical background [0003] There are two development trends of panel technology at present: low power consumption and high transmittance. Both low power consumption and high transmittance are closely related to the response time of liquid crystal. The response time of the existing anisotropic liquid crystal has become saturated with the development in recent years, and it is difficult to get a greater improvement. The blue phase liquid crystal presents the advantages that the traditional liquid crystal does not have: [0004] First: With a sub-millisecond response time, it is possible for the liquid crystal display to realize a field sequential color display mode, which can also greatly reduce dynamic artifacts, and the resolution and optical efficiency of the d...
