Abstract

Apparatuses and methods for forming displays are claimed. One embodiment of the invention relates to forming a flexible active matrix display along a length of flexible substrate. Another embodiment of the invention relates to forming multiple flexible displays along a continuous flexible substrate. Another embodiment of the invention relates to forming a flexible display along a flexible reflective substrate. Another embodiment of the invention relates to using FSA generally with a flexible web process material. Another embodiment of the invention relates to using FSA and a deterministic method such as “pick and place” to place objects onto a rigid substrate or onto a web process material. Another embodiment of the invention relates to using web processing to deposit and/or pattern display material through an in-line process.

Claims8

Dependent claims

A device for continuously feeding a flexible substrate and a display tape through a production line to form a display panel comprising:

a first drive belt disposed on a first plurality of support members to traverse a flexible substrate about a stationary point;
a second drive bell disposed on a second plurality of support members to traverse a display tape about the stationary point;
said flexible substrate disposed on a first drive belt wherein the flexible substrate has apertures;
a display tape deposited on the second drive belt wherein the display tape has apertures;
a slurry comprising a plurality of shaped blocks is placed onto the substrate;
a container stores excess slurry;
the first drive belt has adjustable fasteners corresponding to the apertures of the flexible substrate;
the second drive belt has adjustable fasteners corresponding to the apertures of the display tape;
and
the flexible substrate is coupled to the display tape.
