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.

Method of liquid crystal alignment for a flexible LCD with micro-grooves

A color filter manufacturing method for a plastic substrate uses an extrusion process to form a plastic substrate with multiple grooves. Then, it uses inkjet printing method to jet photo resists into the groove of the plastic substrate after defining the primary colors of red R., green G., and blue B. The method can overcome the problem happened in the conventional CF photolithography process. This, therefore, can simplify the manufacturing process, and can apply to the large-area plastic substrate of a color filter.

Color filter manufacturing method for a plastic substrate

The present invention discloses a method for manufacturing liquid crystal display (LCD) device by utilizing photopolymer. A first photopolymer layer is coated on the support substrate and the substrate having a buffer layer is treated by photopolymerization. A substrate is treated by processes for forming an electrode layer, an alignment layer and projections as required by general LCD manufacturing. A second photopolymer layer is coated on the substrate having a plurality electrode patterns, an alignment layer and projections. Mask exposure is applied to the substrate and the photopolymer forms a polymer wall. Alternatively molding can be applied to the substrate along with linear ultra violet exposure. The photopolymer layer is hardened by such process and forms a polymer wall with alignment. The cavities in the polymer wall are filled with mixture of liquid crystal and small amount of photopolymer. The support substrate and the substrate are aligned and treated by mask exposure for coupling the support substrate to the substrate via photopolymerization. The support substrate is separated from the substrate and accordingly a single substrate LCD device is generated. The same method can be applied to manufacturing process for a LCD device without a substrate. The method increases yield rate also provides a different method for manufacturing a LCD device.

Method for manufacturing liquid crystal display

A touch screen mounting assembly for a liquid crystal display panel (LCD) and a method for fabricating a touch screen mounting assembly for use on a LCD panel are disclosed. The mounting assembly includes a bottom frame that has a plurality of attachment means mounted thereon, a backlight panel that has a plurality of pressure-sensitive transducers mounted thereon, a liquid crystal display panel, and a top frame for exerting pressure when mounted to the bottom frame such that a plurality of compressible springs biases the LCD panel towards the bottom frame when touched or contacted by a user. The pressure-sensitive transducers may be suitably piezoelectric transducers that produce a flow of electricity upon sensing a pressure.
