  • Patent number: 7641935
    Abstract: The present invention is method of liquid crystal alignment for a flexible LCD with micro-grooves comprising: coating a thermoplastic material onto a conductive film; heat embossing a plurality of micro-grooves formed by a mold, wherein the surface of said mold forms said plurality of micro-grooves; and aligning said plurality of micro-grooves with an aligning wall and grooves. The present invention also adds a plurality of liquid alignment technology in roll-to-toll micro cell LCD processes. The plurality of liquid alignment technology lets the micro cells of the LCD from without aligning with an alignment LCD mode (such as TN, VA or horizontal alignment) and achieves a better contrast and display quality.
