Methods of driving colour sequential displays

Номер: US20120007899A1

A method of driving a display uses first ( 4 ) and second ( 5 ) illumination cycles of the display. In each cycle, a first set of pixels ( 1′ ) is illuminated with a first color (R, G) and a second set of pixels ( 2′ ) is illuminated with a second color (G, B). The first and second colors of the two cycles together include at least three colors (R, G, B) for forming an image. This method provides a sequential drive scheme, in that at least two cycles are used with different color properties. However, each cycle uses at least two different colors, so that each cycle is not a single color across the whole display area. In this way, the color sequence is alternated spatially as well as temporally.

A second oxide component is formed over the first oxide crystal component. Crystal growth is performed by a second heat treatment using the first oxide crystal component as a seed, so that a second oxide crystal component is formed. Thus, a stacked oxide material is formed. A transistor with a high mobility is formed using the stacked oxide material and a driver circuit is formed using the transistor.

Entropy coder supporting selective employment of syntax and context adaptation. In video coding, different entropy coding is selectively and adaptively employed based on local and/or remote consideration(s). For example, certain entropy coding may be context adaptive while other entropy coding may be non-context adaptive, and may operate in accordance with syntax or without syntax. Selective adaptation between context adaptive entropy coding and non-context adaptive entropy coding, as well as those which operate using syntax or without syntax may be made based on one or more local and/or remote characteristic(s). Transitioning between the various end to end configurations midstream can occur upon reference frame transitions with appropriate header information leadoff in a given bitstream. A given device (e.g., encoder or transcoder) may be implemented to transition independently, in cooperation with, or under the direction/coordination with one or more other devices within the communication system.

Display ground plane structures may contain slits. Image pixel electrodes in the display may be arranged in rows and columns. Image pixels in the display may be controlled using gate lines that are associated with the rows and data lines that are associated with the columns. An electric field may be produced by each image pixel electrode that extends through a liquid crystal layer to an associated portion of the ground plane. The slits in the ground plane may have a slit width. Data lines may be located sufficiently below the ground plane and sufficiently out of alignment with the slits to minimize crosstalk from parasitic electric fields. A three-column inversion scheme may be used when driving data line signals into the display, so that pairs of pixels that straddle the slits are each driven with a common polarity. Gate line scanning patterns may be used that enhance display uniformity.
