Abstract
The invention discloses a colorful multi-scan driving method for a color sequence multi-task scan liquid crystal colorful display. A multi-task scan signal provides at least two scans in the same color sequence cycle, so that the luminous fluxes of the backlights with different colors are increased and the total amount thereof is closer so as to obtain the degree of saturation of the better color and the degree of uniformity of the column. The invention can also cooperate with the control of the backlight to enable the backlights with different colors to have non-luminance time when being transferred, and enable the non-luminance time to overlap with the light mixing area caused by the liquid crystal optical response delay, to avoid mixing the backlights with different colors, so that the display color difference caused by mixing colors can be avoided, and the correct derivation colors of the original design can be generated.
Description
Technical field
The present invention relates to a kind of multitask scanning and display method of color-sequence liquid crystal colorful display, relate in particular to a kind of driving method that improves luminous flux, color saturation is increased.
Background technology
Color-sequence liquid crystal colorful display mainly is to pass the liquid crystal photic gate door by switching the multicolor backlight source in proper order, closing and opening by control liquid crystal photic gate door, produce former pure color figure field in proper order, colour mixture produces colorful demonstration by the persistence of vision of human eye, see also shown in Figure 1, control signal 1 is used to drive the liquid crystal photic gate door and closes and open, and the liquid crystal photic gate door is subjected to the restriction of liquid crystal molecule response time, the breakthrough curve 2 of liquid crystal photic gate door can't immediate reaction, thereby the phenomenon that has an operating lag 3 produces.
Please consult Fig. 2 and shown in Figure 3 again, it is sequential chart and each color light flux synoptic diagram of known color-sequence liquid crystal colorful display of known color liquid crystal multitask scanning technique, it is that illustration shows explanation with 1/4 dutycycle (Duty), C0, C1, C3 (C2 does not omit and draws) represents the sequential chart of TCM scanning liquid crystal panel common column (Row/Common) signal 4 respectively, Sn then is the sequential chart of liquid crystal panel capable (Column/Segment) sections sweep signal, and it cooperates in proper order backlight 5 of the multicolor backlight source of switching (to be illustrated as ruddiness 6 (R) together, green glow 7 (G), blue light 8 (B) switches in proper order) use.
The sequential chart of the color liquid crystal multitask scanning technique by Fig. 2 drives color-sequence liquid crystal colorful display, its each color light flux synoptic diagram as shown in Figure 3, the integral area (being luminous flux) of its each color ruddiness 6 (R), green glow 7 (G), blue light 8 (B) is little and inconsistent, can be mixed into the preorder look simultaneously, thereby see also shown in Figure 4, row luminous flux 9 can be coloured dark and distortion, colour mixture be listed as unequal problem.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind of multi-scan driving method of look preface multitask scanning liquid color display, and it can increase luminous flux and total amount is more approaching, to reduce sections difference, makes the color of demonstration that better degree of saturation and row uniformity coefficient be arranged.
Secondary objective of the present invention is, still can keep the demonstration of former pure color and the problem of non-mixed color after increasing luminous flux, improves the colour cast problem of induced color.
Based on above-mentioned purpose, the invention provides a kind of colorful multi-scan driving method, the step of this method comprises:
Provide one at least two kind of color and switch in proper order backlight;
At least one multitask sweep signal is provided, and the circulation of the look preface of this multitask sweep signal is to switching time that should different colours backlight, and this multitask sweep signal provides at least twice scanning in a look preface circulation.
This backlight can be controlled and when switching color, have a fluorescent lifetime not, and make this not fluorescent lifetime and the mixed light area overlapping that is caused because of the liquid crystal optical response time delay, can avoid the different colours colour mixture backlight in this multicolor backlight source.
In view of the above, the present invention provides at least twice scanning in a look preface circulation, thereby can increase luminous flux and total amount is more approaching, to reduce row difference, increase color saturation and row uniformity coefficient, the colour mixture backlight that to avoid different colours that is provided with by fluorescent lifetime not simultaneously, thereby when pure color shows, can avoid colour mixture and cause the demonstration aberration, and when the tertiary colour of deriving shows, can produce the correct former design color of deriving, to satisfy user's demand.

Embodiment
For making those skilled in the art more deep understanding and approval be arranged, now enumerate preferred embodiment and conjunction with figs. is described as follows to feature of the present invention, purpose and effect:
See also Fig. 5 and shown in Figure 6, the present invention is the colorful multi-scan driving method of look preface multitask scanning liquid color display 60, its provide one have at least two kinds of colors and switch in proper order backlight 20, and this backlight 20 can have a fluorescent lifetime 21 not when switching color, this backlight 20 can have in proper order ruddiness 201, the green glow 202 and blue light 203 that switches, and these multicolor backlight 20 sources can in produce this backlight 20 this not fluorescent lifetime 21 initially arranged.
The invention provides at least one multitask sweep signal 30,31 pairs of the look preface of this multitask sweep signal 30 circulations should 20 different colours backlight switching time, and this multitask sweep signal 30 provides at least twice scanning 32 in a look preface circulation 31, it should be noted that, the illustrated multitask sweep signal 30 of the present invention is to be the example explanation with dutycycle 1/4, C0, C1, C3 (C2 does not omit and draws) represents the liquid crystal panel common column sequential chart of timesharing respectively, Sn then is the sequential chart of the capable sections sweep signal of liquid crystal panel, and each look preface circulation 31 is classified the representative explanation as for four scannings are provided.
Please consult shown in Figure 7 more in the lump, its sequential chart for the color liquid crystal multitask scanning technique by Fig. 6 drives each the color ruddiness 201 behind the color-sequence liquid crystal colorful display, green glow 202 and blue light 203 luminous flux synoptic diagram, as seen from the figure, the present invention provides at least twice scanning 32 in a look preface circulation 31, therefore can increase luminous flux greatly and total amount is more approaching, to reduce row difference, so can increase the saturation degree and the row uniformity coefficient of display color, may command of the present invention again this fluorescent lifetime 21 is not overlapping with the mixed light district 40 that is caused because of the liquid crystal optical response time delay, so color of its effective viewing area 50, can not sneak into other color, avoid colour mixture and cause the demonstration aberration, can produce correct former design look and derive color.
As mentioned above, the present invention provides at least twice scanning 32 in look preface circulation 31, as shown in Figure 8, row luminous flux 70 can increase and total amount more approaching, to reduce row difference, again its this backlight 20 forms this not fluorescent lifetime 21 by modulation, thereby when pure color shows, can avoid sneaking into backlight 20 of other color, and do not have a problem that shows colour mixture, and when the tertiary colour of deriving shows, can produce the correct former design color of deriving, to satisfy user's demand.
Only above-mentioned is the preferred embodiments of the present invention only, is not to be used for limiting scope of the invention process.Be that all equalizations of being done according to the present patent application claim change and modification, be all claim of the present invention and contain.
