Column spacer design for a display incorporating a third metal layer

摘要

A display that contains a column spacer arrangement which takes advantage of a protrusion on a TFT substrate is provided. One set of column spacers is disposed on top of the protrusion, while a second set of column spacers of substantially the same height as the first set of column spacers are disposed throughout the display. In this way, the display is adequately protected against deformation from external forces while at the same maintaining enough room to allow for a liquid crystal to spread out during the manufacturing process.

主权项

1. A display pixel stackup, comprising:
a top cover; a transistor substrate; a plurality of common electrodes disposed on the transistor substrate; a metal layer in contact with a first common electrode of the plurality of common electrodes, wherein the metal layer forms a protrusion on the transistor substrate; a fluid layer disposed between the top cover and the transistor substrate; and a plurality of column spacers, wherein a first column spacer of the plurality of column spacers is configured to contact the protrusion on the transistor substrate and directly touches the metal layer, wherein the plurality of common electrodes correspond to one or more pixel electrodes for generating an electric field across at least one pixel of the display pixel stackup.
