Abstract

See full text

This disclosure provides a method for filling printing ink in an electrowetting display substrate and a method for producing the electrowetting display panel. The electrowetting display substrate comprises a first substrate. The first substrate has pixel grids formed by pixel walls. The method for filling printing ink in an electrowetting display substrate comprises steps of: filling a mixture of an oil-containing printing ink and a solvent into the pixel grids, wherein the solvent has a boiling temperature lower than that of the oil, and the printing ink is soluble in the solvent; and vaporizing the solvent at a temperature that is lower than the boiling temperature of the oil and higher than or equal to the boiling temperature of the solvent. The method may adjust the filling height of the printing ink effectively, and allow the filling heights of the printing ink in all pixel grids to be substantially the same, so as to enhance the display effect of the electrowetting display panel.
