Description

For the display control method of display
Technical field
The present invention has about a kind of display control method for display, and is particularly to a kind of polychromeThe display control method of light source display.
Background technology
Rapidly, wherein liquid crystal display (liquidcrystaldisplay, LCD) more in Display Technique development at presentTo be employed widely, and as the image output equipment of various electronic installations. Current liquid crystal on the marketDisplay is white light source display mostly, white light source display have the liquid crystal panel that is full of liquid crystal withWhite light source, wherein liquid crystal panel has thin film transistor (TFT) (thinfilmtransistor, TFT) matrix and rightMultiple colo(u)r filters that should each pixel (pixel).
Because liquid crystal itself does not have color, therefore each pixel can be divided into three sub-pixels, and these three sonsPixel correspondence has redness, green and blue colo(u)r filter, so that white light source display can be smoothGround reaches the colored effect showing.
The light transmittance of each sub-pixel on liquid crystal panel, can be by thin film transistor (TFT) corresponding to each sub-pixelThe driving voltage (or being called source drive signal) that source electrode receives is adjusted. Or rather, do not executingIn alive situation, light can change phase place because of liquid crystal molecule phase difference, is torsion at liquid crystal cellUnder type liquid crystal arrangement, this liquid crystal cell and between orthogonal polarizers, under suitable phase difference design, lightLine can pass through, but is adding after voltage, and liquid crystal molecule rearranges, and changes light phase poor, so lightTo have at least a portion is blocked. Briefly, can be by adjusting film crystalline substance corresponding to each sub-pixelThe driving voltage of body pipe, controls the liquid crystal of corresponding sub-pixel, with the light transmittance of adjusting each sub-pixel (also,The light transmittance of liquid crystal can be relevant to its voltage applying or electric field).
Adjust and the effect of multiple colo(u)r filters by the light transmittance of the multiple sub-pixels to each pixel,Each pixel can according to the ruddiness of the multiple sub-pixels on its space, green glow and blue light value come determine itThe color and the brightness that show.
In addition, also have the liquid crystal panel of the liquid crystal display of a type not there is colo(u)r filter, this type ofThe liquid crystal display of type is called color sequential display, this color sequence displayer (colorsequencedisplay) toolThere are redness, green and blue light light source. In polychromatic source display, picture cycle be divided into first toThe 3rd sprite cycle. Red, green and blue light light source can be respectively in the first to the 3rd sprite cycleBe unlocked. So, the successfully specified each pixel of display video data of polychromatic source displayColor. Briefly, the shown color of each pixel of polychromatic source display and brightness be byRuddiness, green glow and the blue light of three different times is by ruddiness, green glow and blue light value institute structure after liquid crystalBecome.
But, when look order is presented at continuous show image picture at present, if there is fast moving in image frameTarget, may colouredly separate the phenomenon of (colorbreak). Even, sometimes because finger or thingProduct rock before user, the phenomenon that polychromatic source display too may coloured separation. Therefore,For user, the display effect of polychromatic source display may showing unlike white light source displayShow that effect comes outstandingly.
If solve the above problems, need liquid crystal material (each sub-pixel that liquid crystal reaction speed is exceedingly fastReaction time of liquid crystal must be less than 4 microseconds), and picture refreshing rate (framerate) more will be from former accordingly60 hertz that come are promoted to 180 hertz, even 240 hertz. But, current liquid crystal material on the marketMaterial is also difficult for the reaction speed demand that reaches above-mentioned. In addition, even if there is on the market the corresponding liquid crystal material canTo reach the demand, but also will be very according to the cost of the produced color sequential display of this modeGround is high.
In addition, for the liquid crystal display of normal white mode, for example twisted nematic (TwistNematic,TN) liquid crystal display, if will make the light transmittance of the liquid crystal display of normal white mode decline, needs to applyLarger driving voltage is controlled liquid crystal. Therefore, lower (also in the brightness of at least a portion of image frameThat is, the brightness of some pixel is lower) time, the liquid crystal display of normal white mode will have larger power consumption.On the contrary, for the liquid crystal display of normal black pattern, for example wide viewing angle technology (FringeFieldSwitching), multiregional vertical align (Multi-domainVerticalAlign) or transverse electric field effect are aobviousShow technology (In-PlaneSwitching) liquid crystal display, if to make normal black pattern liquid crystal display thoroughlyLight rate rises, and needs to apply larger driving voltage and controls liquid crystal. Therefore, at image frame extremelyFew a part of brightness is when large (also, the brightness of some pixel is larger), the liquid crystal display of normal black patternDevice will have larger power consumption.

If it is not inclined to one side that judged result represents region picture 32To the color of multiple coloured light light sources 144 at least one of them, and if judged result represent region picture 32Relatively do not lack multiple coloured light light sources 144 color at least one of them, perform step S408.
In step S406, time schedule controller 106 is according to judged result control light source driving circuit 142Produce the multiple coloured light light sources 144 of drive current to corresponding region picture 32 in light source module 14, with rightMultiple coloured light light sources of corresponding region picture 32 are adjusted and are controlled. In more detail, if region pictureFace 32 be partial to multiple coloured light light sources 144 color at least one of them, by corresponding region picture 32The coloured light light source 144 of the color of being partial to lightens, or/and by other colors of corresponding region picture 32Coloured light light source 144 dims or closes. If region picture 32 lacks the face of multiple coloured light light sources 144 relativelyLook at least one of them, the coloured light light source 144 of the color corresponding region picture 32 being lacked relativelyDim or close, or/with by the coloured light light source 144 beyond 32 relative colors that lack of corresponding region pictureLighten. In step S408, time schedule controller 106 is according to judged result control light source driving circuit 142Produce drive current to multiple coloured light light sources 144 of corresponding region picture 32 in light source module 14, with justOften open multiple coloured light light sources 144 of corresponding region picture 32, also, uncomfortable by force, do not dim with notClose multiple coloured light light sources 144 of corresponding region picture 32.
In step S410, processor 104 or operating system 102 judged whether region picture 32 or34 is not selected. If there is region picture 32 or 34 not selected, S402 goes back to perform step. IfAll Ranges picture 32,34 is all selected, finishes display control method. So, by this enforcementThe demonstration control algorithm of example, can reduce the impure phenomenon of colour gamut after the coloured light colour mixture of display 1.
Along band explanation, the coloured light light source of the corresponding color of above-mentioned reduction corresponding region picture is launchedThe bright dark implementation of coloured light can be by progressively reducing in multiple picture subcycles of picture cycleOr point echelon reduces the side of the drive current of the coloured light light source 144 of the corresponding color of corresponding region picture 32Formula is reached. But this kind of implementation is not in order to limit the present invention.
Then, comprise that taking multiple coloured light light sources 144 redness, green and blue coloured light light source carry out as exampleExplain orally. Be partial to redness when region picture 32 and relatively lack, display control method can be drawn corresponding regionThe red coloured light light source of face 32 lightens, or/and by the blueness of corresponding region picture 32 and green coloured light light sourceDim or close. When region picture 32 lacks green and blueness relatively, display control method is by correspondenceThe blueness of region picture 32 and green coloured light light source dim or close, or/and red coloured light light source is lightened.Be partial to cyan when region picture 34 and relatively lack, display control method can be by corresponding region picture 34Green and blue coloured light light source lightens, or/and the red coloured light light source of corresponding region picture 34 is dimmed orClose. When region picture 34 lacks redness relatively, display control method is by corresponding region picture 34Red coloured light light source dims or closes, or/and green and blue coloured light light source are lightened. When region picture32 be not partial to any color or relatively do not lack any color, for example region picture 32For white, normally open multiple coloured light light sources of corresponding region picture 32.
What deserves to be explained is, multiple coloured light light sources of corresponding region picture 32 and 34 can be controlled independentlySystem, therefore, described display control method can be at same picture cycle control corresponding region picture 32With the unlatching of multiple coloured light light sources of 34, close and adjust the bright of coloured light that multiple coloured light light sources launchSecretly.
In another embodiment, the number that picture cycle can corresponding region picture 32 and 34, andBe divided into multiple picture subcycles, for example first to three-picture subcycle, and draws first to the 3rdIn the face cycle, control respectively multiple coloured light light sources of corresponding region picture 32 and 34 unlatching, close withAdjust the bright dark of coloured light that multiple coloured light light sources launch.
Please refer to Fig. 3 and Fig. 5, Fig. 5 is the drive current of multiple coloured light light sources of the embodiment of the present inventionOscillogram. In this embodiment, picture cycle PF is divided into first to three-picture subcycle PF1～PF3, and multiple coloured light light sources of image frame 3, region picture 32 and 34 are drawn respectively at first to the 3rdIn face cycle PF1～PF3, be unlocked, close or adjust power, bright dark.
When image frame 3 deflections red (or image frame 3 lacks green and blue relatively) and regionWhen picture 32 and 34 is partial to respectively green and blueness, (or region picture 32 lacks red and blue relativelyLook and region picture 34 lack red and green relatively), the red light light source of corresponding image frame 3 inIn the first picture subcycle PF1 of picture cycle PF, be unlocked, the green light light of corresponding region picture 32Come from the second picture subcycle PF2 of picture cycle PF and be unlocked, and the indigo plant of corresponding region picture 34Coloured light light source is unlocked in the three-picture subcycle PF3 of picture cycle PF.
In addition, in this embodiment, the green of corresponding image frame 3 and blue light light source also can be in picturesIn the first picture subcycle PF1 of face cycle PF, dimmed, closed or reduce the opening time (increase is closedTime), or/with the red light light source of corresponding image frame 3 can be in the first picture week of picture cycle PFIn phase PF1, lightened; The redness of corresponding region picture 32 and blue light light source can be in picture cycle PFIn the second picture subcycle PF2, dimmed, closed or reduced the opening time (increasing the shut-in time), or/With the green light light source of corresponding region picture 32 can be in the second picture subcycle PF2 of picture cycle PFLightened; And the redness of corresponding region picture 34 and green light light source can be drawn in the 3rd of picture cycle PFIn face cycle PF3, dimmed, closed or reduced the opening time (increase shut-in time), or/with corresponding districtThe blue light light source of territory picture 32 can be lightened in the second picture subcycle PF2 of picture cycle PF.
In Fig. 5, the degree that green light light source is dimmed from PF2 in picture subcycle PF1 can be different,And degree that blue coloured light light source is dimmed in picture subcycle PF1 and PF2 be unlocked, closeTime can be different. Generally speaking, the present invention adjusts the closing of coloured light light source, unlatching and bright dark modeNot as limit.
For instance, in the first half section of the first picture subcycle PF1 (blue light light source be not unlocked before)Shown image frame 3 with red colour system for leading and lacking blue colour system, therefore red coloured light light source quiltNormally open, green coloured light light source can be dimmed, and blue coloured light light source is closed. In the first pictureIn the second half section of face cycle PF1, (blue light light source be unlocked after) shown image frame 3 is with rednessFor leading and lacking green colour system, therefore red and blue coloured light light source is normally opened with blue colour system,And green coloured light light source can be dimmed.
(blue light light source be not unlocked before) shown district in the first half section of the second picture subcycle PF2Territory picture 32 is with green colour system for leading and lacking blue colour system, and therefore green coloured light light source is normally openedOpen, red coloured light light source can be dimmed, and blue coloured light light source is closed. In the second picture subcycleIn the second half section of PF1, (blue light light source be unlocked after) shown region picture 32 is main with green,Therefore green coloured light light source is normally opened, and red and blue coloured light light source can be dimmed. InRegion picture 34 shown in three-picture subcycle PF3 is taking basket look colour system as main and shortage redness and greenLook colour system, therefore basket look coloured light light source is normally opened, and green is closed with red light light source.
(another embodiment of display control method)
Please refer to Fig. 6, Fig. 6 is the liquid of the respective pixel of the display of the normal white mode of the embodiment of the present inventionThe brilliant driving voltage receiving and the curve map of light transmittance. As shown in Figure 6, when the liquid crystal of respective pixel receivesWhile arriving larger driving voltage, the light transmittance of respective pixel declines, or the darkness of respective pixel rises. IfMake the light transmittance of pixel lower than pixel light transmittance threshold T TH, need to apply a larger drivingVoltage, and along with the rising of driving voltage, the light transmittance decrease speed of pixel also eases up. When whole imageThe image frame pixel light transmittance (average transmittances of all pixels of for example image frame) of picture is lowerTime, the driving voltage that the source electrode of each thin film transistor (TFT) is received is larger, may cause the electricity of displayEnergy consumes excessive, and does not meet the environmental protection trend of current energy-saving and carbon-saving.
In addition, the light transmittance of each pixel is relevant to the GTG value of each pixel, and the GTG value of each pixel is lower,The light transmittance of each pixel is lower. If in advance the GTG value of each pixel is promoted to the light transmittance of each pixelWill reduce, now also can reach the effect that reduces driving voltage. Meanwhile, because the lifting of light transmittance,Therefore can dim accordingly or control the closing of coloured light light source, bright dark and opening time, with furtherReduce the power consumption of coloured light light source, and reach better energy-saving effect.
For instance, in Fig. 6, pixel light transmittance L1 and L2 be lower than pixel light transmittance threshold T TH,And its corresponding driving voltage is V1 and V2. Now, can be for example, with particular power (3 times) by pixelLight transmittance L1 and L2 are promoted to L1 ' and L2 ', and the pixel light transmittance L1 ' driving voltage corresponding with L2 'For V1 ' and V2 ', driving voltage V1 ' and V2 ' are less than respectively voltage V1 and V2. Meanwhile, according to specificThe inverse of multiplying power dims or controls the closing of coloured light light source, bright dark when opening by corresponding coloured light light sourceBetween, to maintain the shown color of original pixel and brightness. So, can effectively reduce displayPower consumption.
In addition, for the display of normal black pattern, still can be by pixel light transmittance threshold T THPixel light transmittance heighten with particular power, although, the corresponding driving electricity of pixel light transmittance after heighteningPress can rise, but because can according to the inverse of particular power, corresponding coloured light light source be dimmed accordingly orControl the closing of coloured light light source, bright dark and opening time, to maintain the shown color of original pixel and brightSpend, therefore can reduce the drive current of coloured light light source. The drive current of minimizing coloured light light source is savedThe power consumption that power consumption increases much larger than the lifting of driving voltage, therefore, generally speaking, showsBe so incensed that power consumption still can effectively reduce.
Generally speaking, can be by the darkness of light transmittance, GTG value or each pixel of the each pixel of lifting and rightShould adjust the unlatching of coloured light light source, bright dark, shut-in time, reduce the power consumption of display.
