Logo patterning methods for liquid crystal displays

摘要

A display may have a thin-film transistor (TFT) layer and a color filter layer. The TFT layer may have a first substrate, a first black masking layer, a planarization layer, and a layer of TFT circuitry on the planarization layer. The color filter layer may have a second substrate and a second black masking layer on the second substrate. A portion of the inactive area may serve as a logo area for displaying desired information to the user. A reflective structure may be formed on the bottom surface of the planarization layer, on the bottom surface of the first substrate, on the bottom surface of the second substrate, or on the upper surface of the first substrate in the logo area. In another embodiment, the logo area may be backlit by transmitting light through one or more openings in the first and second black masking layers in the logo area.

主权项

1. Display circuitry having an active display area surrounded by an inactive border area, comprising:
a thin-film transistor substrate; a color filter substrate; a backlight unit, wherein the color filter substrate is interposed between the backlight unit and the thin-film transistor substrate; and a reflective structure that is formed in the inactive border area and that reflects ambient light to display predetermined information.
