Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, clear, complete description is carried out to the technical scheme in the embodiment of the present invention.Obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Be illustrated in figure 1 the structural representation of the liquid crystal indicator of negative field sequential.The liquid crystal indicator of this negative field sequential comprises the first negative field sequential liquid crystal display cells 20 and the second negative field sequential liquid crystal display cells 30.
First negative field sequential liquid crystal display cells 20 is contrary with the direction of twist of the second negative field sequential liquid crystal display cells 30, mutually compensates, and adjacent substrate frictional direction is mutually vertical.First polaroid 10 of the first negative field sequential liquid crystal display cells 20 is mutually vertical with the second polaroid 40 of the second negative field sequential liquid crystal display cells 30.Second polaroid 40 is arranged in backlight 50.First negative field sequential liquid crystal display cells 20 and the second negative field sequential liquid crystal display cells 30 are TN box or STN(SuperTwistedNematic, super-twist nematic liquid crystal) box structure; Or one of them is TN box or STN box, and another is 1/2 wave plate; Or one of them is TN box or STN box, and another is compensate film.
A negative field sequential liquid crystal display cells in first negative field sequential liquid crystal display cells 20 and the second negative field sequential liquid crystal display cells 30 is as ITOheater(IndiumTinOxide, plated film transparent conducting glass) heater(heating film), another negative field sequential liquid crystal display cells is heated.
Be illustrated in figure 2 the friction schematic diagram of the liquid crystal indicator of negative field sequential.Adjacent substrate frictional direction is ± 45 ° in the present embodiment.First polaroid 10 of the first negative field sequential liquid crystal display cells 20 is mutually vertical with the second polaroid 40 of the second negative field sequential liquid crystal display cells 30.First negative field sequential liquid crystal display cells 20 is contrary with the second negative field sequential liquid crystal display cells 30 direction of twist, and mutually compensate, adjacent substrate frictional direction is mutually vertical.Like this by compensating, good dark-state and wider visual angle can be reached.
In the present invention, above structure can carry out corresponding change according to practical applications such as visual angles.First negative field sequential liquid crystal display cells 20 and the second negative field sequential liquid crystal display cells 30 twist angle can be designed as 70 ° ~ 120 °, 250 ° ~ 290 °, preferably 90 ° and 280 °.
Be illustrated in figure 3 the collocation schematic diagram of two liquid crystal display cells of the liquid crystal indicator of negative field sequential.
Figure (a) in the first negative field sequential liquid crystal display cells 20(Cell1) with the second negative field sequential liquid crystal display cells 30(Cell2) collocation be: Cell1 and Cell2 one of them not light requirement carve, do compensate with or simultaneously as ITOheater, the heating of another box can be given under low-temperature condition, strengthen its cryogenic property.
In figure (b), the collocation of Cell1 and Cell2 is: mode one: when figure complexity easily causes short circuit or driving force deficiency, and Cell1 display part figure, Cell2 shows remainder figure.Mode two: Cell1 and Cell2 all carve electrode, can be designed by Graphic Pattern Matching, by the figure of collocation displays more than four kinds such as opening respectively about cooperation Cell2 bottom, unlatching Cell1 top or two boxes.
Be illustrated in figure 4 the process flow diagram of the driving method of the liquid crystal indicator of negative field sequential.Step S100, provides the first negative field sequential liquid crystal display cells 20 and the second negative field sequential liquid crystal display cells 30.Step S102, one of them negative field sequential liquid crystal display cells display graphics.Step S103, another negative field sequential liquid crystal display cells compensates one of them negative field sequential liquid crystal display cells, and compensation box now can replace with 1/2 wave plate or liquid crystal type compensate film.Another field sequential liquid crystal display element provides heating film to heat one of them negative field sequential liquid crystal display cells.
