Abstract

A method for manufacturing a color display provides a bottom substrate, injects a liquid display media onto the bottom substrate, and disposes a sealing substrate on the liquid display media, such that the liquid display media is contained between the sealing substrate and the bottom substrate. The method also aligns an image device corresponding to the bottom substrate and transfers a color coating onto the sealing substrate by a laser device through a laser thermal transfer process to form a color filter layer on the sealing substrate.

Claims (11)

1. A method for manufacturing a color display, comprising:

providing a bottom substrate having at least one alignment marker;

injecting a liquid display media onto the bottom substrate;

disposing a sealing substrate on the liquid display media, such that the liquid display media is contained between the sealing substrate and the bottom substrate;

aligning an image device with the bottom substrate; and

transferring a color coating onto the sealing substrate by a laser device through a laser thermal transfer process to form a color filter layer on the sealing substrate.

2. The method for manufacturing the color display as claimed in claim 1 , further comprising forming a grid structure layer having a plurality of grid structures formed between the sealing substrate and the bottom substrate.

3. The method for manufacturing the color display as claimed in claim 2 , wherein the grid structures define a plurality of display pixels.

4. The method for manufacturing the color display as claimed in claim 3 , wherein the image device is aligned with the bottom substrate by the display pixels after the display pixels are driven.

5. The method for manufacturing the color display as claimed in claim 1 , wherein the color coating comprises a thermal sensing layer and a pigment layer, and the thermal sensing layer transfers the pigment layer onto the sealing substrate to form the color filter layer when a laser beam from the laser device hits the color coating.

6. The method for manufacturing the color display as claimed in claim 1 , wherein the image device is aligned with the bottom substrate by the at least one alignment marker.
