Abstract
A particular multi-domain vertical alignment (MVA) liquid crystal display (LCD) can offer a high contrast ratio and a wide symmetrical viewing angle, without rubbing, protrusion surface, or ITO slit geometry. The viewing angle can be further enlarged by the use of optical compensation films, such as a negative birefringence anisotropic optical film with a vertical optical axis.
Claims51
A multi-domain vertical alignment display, comprising:
- a liquid crystal display device having a fringe field associated with each pixel of the device, the fringe field in each pixel being substantially used to control the liquid crystal tilt direction to create the multi-domain vertical alignment display.
A method of creating a multi-domain vertical alignment display, comprising:
- in a liquid crystal display device having a fringe field associated with each pixel of the device, substantially controlling the liquid crystal tilt direction in each pixel using the fringe field to create the multi-domain vertical alignment display.
18 The method of claim 15, further comprising reducing or eliminating the fringe field from extending into neighboring pixels.
The method of claim 18, wherein reducing or eliminating the fringe field includes installing boundary lines between the neighboring pixels.
A multi-domain vertical alignment display, comprising:
- a first substrate and a second substrate;
- a plurality of rows and a plurality of columns formed on the second substrate, the intersection of which forming a plurality of pixels;
- liquid crystal material disposed between the first and second substrates, liquid crystal molecules having a vertical orientation and each pixel having an associated fringe field when an electric field is applied between the first substrate and the second substrate;
- and
- a controller for substantially providing a tilted orientation of the liquid crystal molecules only the fringe field associated with each pixel.
