Abstract: A dual-frequency bistable liquid crystal display and the liquid crystal mixture thereof includes liquid crystal cell filled with a liquid crystal mixture which contains dual-frequency liquid crystal, chiral compound, and nematic liquid crystal mixture. The liquid crystal mixture has the characteristics of both the dual-frequency liquid crystal and cholesteric liquid crystal. The dual-frequency bistable liquid crystal display is driven in a frequency modulation mode and can be switched between two optical states by taking advantage of the dielectric anisotropy of the liquid crystal, which results in a short switching time and sharp contrast between two optical states. Furthermore, the maintaining of the two optical states requires no voltage, which does not require the use of a high voltage to destabilize the helical structure of the cholesteric liquid crystal, and does not have to go through a metastable stage. Hence, power consumption and switching time are reduced.

Abstract: The present invention discloses a REPEATED-SCAN driving method, which applies to a field sequential color liquid crystal display, wherein each sequential-color cycle of the multiplex-scan signal has at least two stages of scans to increase the luminous fluxes of all colors of backlights and bring closer the total amounts of fluxes, whereby is achieved higher color saturation and better flux uniformity between the rows. Further, the method of the present invention controls the backlights to form dark stages between the intervals respectively of two different colors of the backlights and controls the dark stage to coincide with a color-mixing interval, which is caused by response delay of liquid crystal, to prevent from color distortion caused by color mixing. Therefore, the present invention can generate the pure colors and the designed derived colors accurately.

Abstract: The present invention discloses an FSC LCD enhance driving modulation method, which modulates the timing signal that controls the liquid crystal optical gate to shorten the transit delay caused by optical response delay of liquid crystal and thus increases luminous flux and improves color saturation. The present invention also controls the multi-color backlight source to sequentially emit at least two colored backlights with a dark interval therebetween. The present invention further controls the transit delay to coincide with the dark interval, whereby the latter colored backlight will not mix with the former colored backlight during the transit delay, wherefore the present invention can avoid the color deviation caused by color mixing and can present the designed colors correctly.

Abstract: An image data bus comprises an input port, an output port, and an image register with two ends thereof respectively coupled to the output port and the input port. The image register connects with an LCD driver. A plurality of image data buses is cascaded via using a plurality of cascading signal cables to connect the output ports and the input ports of the image data buses. Image data is sequentially transposed in a first-in-first-out way and transferred from the output port of the front-stage image data bus to the input port of the rear-stage image data bus. The present invention can facilitate flexibly constructing different-size assembled LCD billboards. Further, the present invention can reduce the cables used in wiring an assembled LCD billboard and effectively lower material cost thereof.

Abstract: The present invention discloses a single-level driver is programmed to generate a plurality of segment voltage signals. A multicolor backlight modulation device receives the segment voltage signals and modulating a portion of the segment voltage signals to generate a common voltage signal and at least two synchronous color-separation backlight driving signals driving a backlight source to emitting different-color backlights. The common voltage signal cooperates with the segment voltage signals to form voltage differences which drive a mono-pixel to turn on or turn off in a time-division mode and allow different-color backlights to pass the mono-pixel at the same time. The time-division different-color backlights are accumulated by vision persistence to present a chromatic effect on the mono-pixel. The resultant colors can be intelligently varied via programming the segment voltage signals to achieve diversified multicolor effects.

The new common voltage signals and segment voltage signals cooperate to form voltage differences making a mono-pixel allow different-color backlights to pass and controlling the mono-pixel to turn on or turn off in a time-division mode. The effects of the time-division different-color backlights are accumulated by vision persistence to form different colors on the mono-pixel. Thus, the present invention can enable a monochromatic LCD chip and a mono-pixel to present a multi-color effect.

The accumulated effect of the time-division turn-on and turn-off states enables the same monochromatic pixel to present gray-pixel.
