An improved electronic display that includes components selected to enhance display performance. The improved display includes an active substrate that has a plurality of thin film transistors and a plurality of thermally transferred color filters that include a colorant in a crosslinked binder. The active substrate can also include a black matrix. Other components in the improved display such as a liquid crystal material, spacers, and bottom polarizer, can be selected to enhance display performance characteristics such as brightness, power consumption, response time, weight, and thickness. The invention also provides a method of forming a color filter substrate for displays including the steps of thermally mass transferring a plurality of color filters and crosslinking the plurality of color filters after transfer. Before the crosslinking step, the plurality of color filters can be inspected and removed for reworking of the substrate.

Process for making active substrates for color displays

A microporous liquid impermeable but vapor permeable sheet material useful as a backsheet for disposable absorptive devices such as disposable diapers, incontinent devices, sanitary napkins, and panty liners is disclosed. This backsheet provides unexpected useful attributes such as compatibility with available closure tapes and embossibility with translucent patterns.
