Problems solved by technology

[0004] Since the above-mentioned existing transfer device cannot sense the state of the substrate, when the surface of the substrate is uneven, the pressure per unit area between the substrate and the printing roller will be uneven, thereby affecting the quality of the alignment film.

Embodiment Construction

[0039] The specific implementation manners of the alignment liquid transfer method and the transfer device provided in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] A method for aligning liquid transfer printing provided by an embodiment of the present invention, such as figure 2 As shown, it specifically includes the following steps:

[0041] S101. The transfer roller coated with the pressure-sensing film contacts and transfers the alignment liquid substrate to be transferred, and the pressure-sensing film acquires surface roughness information of each display panel area in the alignment liquid substrate to be transferred;

[0042] S102. According to the obtained surface flatness information of each display panel area in the alignment liquid substrate to be transferred, adjust the printing dot pattern corresponding to each display panel area in the piezoelectric variable layer covering the sur...

Abstract

The invention discloses a directional liquid transfer method and device. In the transfer method, a pressure perception film wrapping a transfer roll can obtain surface evenness information of display panel regions in a directional liquid substrate to be transferred and adjust printing dot patterns in a piezoelectric variable layer wrapping the surface of the printing roll and corresponding to the display panel regions according to the obtained surface evenness information to enable printing dot patterns of the piezoelectric variable layer to be deformed into the shape matched with the display panel regions in the directional liquid substrate to be transferred, so that unit area pressure borne by the display panel regions in the directional liquid substrate to be transferred is uniform when the printing roll conducts directional liquid transferring on the display panel regions in the directional liquid substrate to be transferred, and transfer quality is improved accordingly.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method and a transfer device for aligning liquid transfer. Background technique [0002] In recent years, liquid crystal display panels (Liquid Crystal Display, LCD) have gradually spread in people's lives. A liquid crystal display panel is mainly composed of an array substrate, an opposite substrate, and a liquid crystal layer between the two substrates. The liquid crystal display panel controls the orientation of liquid crystal molecules through an electric field to change the transmittance of the liquid crystal display panel, thereby realizing the display function. In order to arrange the liquid crystal molecules in a certain direction in the initial state, an alignment film needs to be coated on the inner surface of the opposite substrate of the liquid crystal display panel and the inner surface of the array substrate, and the array substrate and the opposit...
