In the display system of LCD, reception comes from a shows signal of processor earlier usually, and then sends a driving voltage by a driver element and order about a display show image.Below will continue above-mentioned prior art is enumerated a known embodiment to be specified in conjunction with graphic.
See also Fig. 1 and Fig. 2, Fig. 1 is the functional block diagram that shows known embodiment, and Fig. 2 shows that picture legibility among the known embodiment, picture show the graph of a relation of time and image time.As shown in the figure, after a processing unit 1 sends shows signal S1 to a driver element 2, can send the display module 3 of driving voltage to a LCD, use driving display module 3 and show dynamic or static picture through the processing of over-drive unit 2.
Wherein, it is after receiving shows signal S1 that picture data is handled sequential memory block 211, stores the complex picture data that shows signal S1 is carried according to carrying out sequential.In the previous picture data memory block 212 is to store the preceding unicursal face data of just having handled.Multiplexer 221 is the usefulness for multiplexing process, timer 222 is to judge and the sequential of carrying out each picture data for treatment circuit 224 with the processing sequential that cooperates picture data, 223 of sound attitude picture judging units are in order to judge that picture datas that institute's desire is handled are dynamically or the picture data of static types, to use that ordering about treatment circuit 224 handles each picture data with the processing mode of correspondence.
As shown in Figure 2, in this known embodiment, it is to be stored in above-mentioned picture data to handle sequential memory block 211 and wait to be sent to this treatment circuit 224 and handle that above-mentioned shows signal S1 includes four stroke face data, four stroke face data include target legibility B1, B2, B3 and the B4 of four correspondences respectively, and four target legibility B1, B2, B3 are to correspond respectively to four picture demonstration time FPT1, FPT2, FPT3 and the FPT4 of even time interval mutually with B4.Wherein, picture shows that time FPT1 includes image time FT1 and FT2, picture shows that time FPT2 includes image time FT3 and FT4, and picture shows that time FPT3 includes image time FT5 and FT6, and picture shows that time FPT4 includes image time FT7 and FT8.
See also Fig. 3, it is the definition mode of display-object vision legibility.As shown in the figure, when driving display picture data with a target drives voltage V, legibility can show among the time FPT at a picture, rise to the pairing target legibility B of target drives voltage V gradually.Simultaneously, Fig. 3 also shows the variation relation of legibility and time simultaneously, and wherein, legibility is the function (this function is an objective function) of time.So-called target visual legibility, a desired value of the visual experience degree of the bright situation of picture being set up at the mankind exactly.The pairing target visual legibility of these stroke face data (promptly the mankind are for the visual experience degree of the bright situation of picture) VB is exactly with this objective function numerical value to the time integral gained in picture demonstration time FPT, and its numerical value equals the area in figure bend zone.
Please continue to consult Fig. 4 to Fig. 5, Fig. 4 shows picture legibility and time-varying relationship figure among the known embodiment, Fig. 4 A is the target visual legibility that shows the first stroke picture data, Fig. 4 B is the target visual legibility that shows the second stroke face data, Fig. 4 C is the adjustment vision legibility after the process of the demonstration the first stroke picture data and the second stroke face data exceeds the quata to drive, and Fig. 5 is driving voltage and the time-varying relationship figure that shows corresponding to Fig. 4.
Driving voltage before this only shows in the two-stroke face data and picture legibility variation relation in respect of time, and please in the lump with reference to figure 1.As shown in the figure, when handling the first stroke picture data, when desiring to make the picture legibility of the first stroke picture data to reach its pairing target legibility B1, if driving voltage is adjusted to the pairing target drives voltage V1 of target legibility B1 drives, then can't in the image time FT1 picture legibility of the first stroke picture data be promoted to target legibility B1 (shown in the dashed curve that indicates V1 among Fig. 4).
So, driving voltage must be heightened to the driving voltage OV1 that exceeds the quata and drive, the picture legibility is able to when image time FT1 (as shown in Figure 4), or in image time FT1, reach target legibility B1, then driving voltage is downgraded target drives voltage V1 at an image time FT2.Then, treatment circuit 224 can be stored in the previous picture data memory block 212 of temporary storage 21 with the first stroke picture data, and then begins to handle the second stroke face data.
When handling the second stroke face data, be to be used as reference data from the partial data that previous picture data memory block 212 captures in the first stroke picture datas, when desiring to make the picture legibility of the second stroke face data to reach its pairing target legibility B2, be that target legibility B1 with the first stroke picture data is a benchmark, drive if driving voltage is adjusted to the pairing target drives voltage V2 of target legibility B2, then can't in another image time FT3 the picture legibility of the second stroke face data be promoted to target legibility B2 (shown in the dashed curve that indicates V2 among Fig. 4) from target legibility B1.
So, driving voltage must be heightened to another driving voltage OV2 that exceeds the quata and drive, the picture legibility is able to when image time FT3 (as shown in Figure 4), or in image time FT3, reach target legibility B2, then driving voltage is downgraded target drives voltage V2 at an image time FT4.Then, treatment circuit 224 is understood the previous picture data memory block 212 of the second stroke face data storing in temporary storage 21, and then begins to handle the 3rd stroke face data.The 3rd stroke face data are similar to the processing mode of preceding two-stroke face data to the processing mode of the 4th stroke face data, then no longer given unnecessary details at this.
By Fig. 4 A to Fig. 4 C,, when driving, can calculate two target visual legibility VB01 and VB02 respectively with this target drives voltage V1 and this target drives voltage V2 in conjunction with aforementioned cognition to the target visual legibility.By that analogy, when exceed the quata with this driving voltage OV1 and OV2 drive, then can calculate two respectively and adjust vision legibility VB1 and VB2.Simultaneously, adjust vision legibility VB1 and VB2 significantly respectively greater than target visual legibility VB01 and VB02.Therefore, the mankind can feel that the picture image that the first stroke picture data and the first stroke picture data presented is brighter more dazzling than predetermined target value.
Allly drive to show at picture that correlative technology field has and know that usually the knowledgeable can both understand, take a broad view of in the above tupe generally have three shortcomings: the first mankind can feel that the picture image that every stroke face data are presented is brighter than predetermined target value; Two to be that every stroke face data are thin handle with reference to last picture data for it, sees the ghost of last picture easily because of the factor of persistence of vision; It three is for every stroke face data, its reaction time need approximately usually an image time the time apart from (as image time FT1 and FT3).

See also Fig. 6 to Fig. 8, Fig. 6 is the functional block diagram that shows preferred embodiment of the present invention, Fig. 7 shows picture legibility and time-varying relationship figure in the preferred embodiment of the present invention, Fig. 7 A is the target visual legibility that shows the first stroke picture data, Fig. 7 B is the target visual legibility that shows the second stroke face data, Fig. 7 C is the adjustment vision legibility that shows after the first stroke picture data and the second stroke face data drive with exceed the quata driving voltage and reference voltage, Fig. 8 is driving voltage and the time-varying relationship figure that shows corresponding to Fig. 7, simultaneously, please contrast Fig. 2 to Fig. 5 in the lump.
As shown in the figure, send above-mentioned shows signal S1 to another driver element 2a at above-mentioned processing unit 1, can send the display module 3 of another driving voltage through the processing of over-drive unit 2a, use driving display module 3 and show dynamic or static picture to above-mentioned LCD.
Wherein, driver element 2a includes a temporary storage 21a and a shows signal processing module 22a.Store an image time of presetting in the temporary storage 21a (as the FT1 to FT8 that Fig. 2 indicated, and build and be equipped with a picture data processing sequential memory block 211a and an adjustment parameter memory block 212a the i.e. image time of eight even time intervals equating with image time of expression respectively).A built-in multiplexer 221a, a timer 222a, a sound attitude picture judging unit 223 and the treatment circuit 224 of being equipped with of shows signal processing module 22a.
Wherein, it is after receiving shows signal S1 that picture data is handled sequential memory block 211a, stores the complex picture data that shows signal S1 is carried according to carrying out sequential.Multiplexer 221a is the usefulness for multiplexing process, timer 222a judges and the sequential of carrying out each picture data for treatment circuit 224a with the processing sequential that cooperates picture data, sound attitude picture judging unit 223a is then in order to judge that the picture data that institute's desire is handled is the picture data of dynamic or static types, to use that ordering about treatment circuit 224a handles each picture data with the processing mode of correspondence.The function of above-mentioned functions square is all similar to known embodiment, and is just different with known embodiment for adapting to following processing mode, and does necessary change.All have at affiliated correlative technology field know that usually the knowledgeable can make corresponding design and adjustment according to following disclosed method with notion, below give unnecessary details no longer especially.
As shown in Figure 7, when handling the first stroke picture data, must make the picture legibility of the first stroke picture data reach its pairing target legibility B1.At this moment, if above-mentioned driving voltage is adjusted to the pairing target drives voltage of target legibility B1 V1 to be driven, then can't be in an image time (Frame Time) FT1 the picture legibility of the first stroke picture data be promoted to target legibility B1, so driving voltage can be modulated into an optimum visual display voltage OV1 ' who is higher than target drives voltage V1 earlier drives, and makes the picture legibility be able to reach target legibility B1 within the optimization driving time OT1 less than image time FT1.For fear of after adjusting, causing the too high problem of vision legibility, then can one reference time RT1 driving voltage involution to is lower than the reference voltage RV of this target drives voltage V1, make the picture legibility level off to a benchmark legibility (be the utmost point drive be bordering on 0 lumen) in this enforcement from target legibility B1 involution.Simultaneously, optimization driving time OT1 shows that with the picture described in the known embodiment time FPT1 equates with the summation of RT1 reference time, that is equals the summation of two image time FT1 and FT2.
Please comparison diagram 7A and Fig. 7 C, when driving, can calculate a target visual legibility VB01 ' according to the mode of above-mentioned integration with the pairing target drives voltage of this target legibility B1 V1.By that analogy, when driving voltage being modulated into the optimum visual display voltage OV1 ' that keeps optimization driving time OT1 and keeping the reference voltage RV of RT1 reference time, also can set up one and adjust function, and utilize this adjustment function calculation to go out one and adjust vision legibility VB1 ' according to the variation relation of picture legibility and time.In order to allow the user when watching the first stroke picture data, can not feel stronger than the lightness of expection, can adjust above-mentioned optimum visual display voltage OV1 ', reference voltage RV, optimization driving time OT1 and reference time RT1, make adjustment vision legibility VB1 ' equal target visual legibility VB01 ', at this moment, can with through the optimum visual display voltage OV1 ', the reference voltage RV that adjustment, optimization driving time OT1 and reference time parameter such as RT1 be stored in above-mentioned adjustment parameter memory block 212a.In the present embodiment, the adjusted optimization driving time OT1 of process approximates the time of 3/4 times of FT1, and reference time, RT1 approximated the time of 5/4 times of FT1.
When handling the second stroke face data, must make the picture legibility of the second stroke face data reach its pairing target legibility B2.At this moment, if above-mentioned driving voltage is adjusted to the pairing target drives voltage of target legibility B2 V2 to be driven, then can't be in an image time FT3 picture legibility of the second stroke face data be promoted to target legibility B2, so driving voltage can be modulated into another optimum visual display voltage OV2 ' that is higher than target drives voltage V2 earlier drives, and makes the picture legibility be able to reach target legibility B2 within another optimization driving time OT2 less than image time FT3.For fear of after adjusting, causing the too high problem of vision legibility, then can one reference time RT2 with the driving voltage involution to the reference voltage RV that is lower than this target drives voltage V2, make the picture legibility level off to the benchmark legibility from target legibility B2 involution.Simultaneously, optimization driving time OT2 shows that with the picture described in the known embodiment time FPT2 equates with the summation of RT2 reference time, that is equals the summation of two image time FT3 and FT4.
Please comparison diagram 7B and Fig. 7 C, when driving, can calculate a target visual legibility VB02 ' according to the mode of above-mentioned integration with the pairing target drives voltage of this target legibility B2 V2.By that analogy, when driving voltage being modulated into the optimum visual display voltage OV2 ' that keeps optimization driving time OT2 and keeping the reference voltage RV of RT2 reference time, also can set up another and adjust function, calculate another according to this and adjust vision legibility VB2 ' according to the variation relation of picture legibility and time.Human when watching the second stroke face data in order to make, can not feel stronger than predetermined lightness yet, can adjust above-mentioned optimum visual display voltage OV2 ', optimization driving time OT2 and RT2 reference time (reference voltage RV still keeps above-mentioned adjusted value), make adjustment vision legibility VB2 ' equal target visual legibility VB01 ', at this moment, can with through the optimum visual display voltage OV2 ', the optimization driving time OT1 that adjustment and reference time RT1, and parameter such as reference voltage RV is stored in above-mentioned adjustment parameter memory block 212a.
On practice utilization aspect, each stroke face data is that the target drives voltage by specific quantity kind (can be 32 kinds or 64 kinds usually) voltage quasi position (Voltage Level) is driven, therefore only need target drives voltage at these 32 kinds or 64 kinds voltage quasi positions calculate pairing 32 groups or 64 groups of driving voltages that exceed the quata respectively, exceed the quata driving time and reference time, and parameter such as reference voltage, and it is stored in adjusts parameter memory block 212a in advance.Thus, can be when handling many strokes face data, self-adjusting parameter memory block 212a loads above-mentioned parameter automatically, and needn't all carry out above-mentioned modulation and adjustment work at every turn.The 3rd stroke face data are similar to the processing mode of preceding two-stroke face data to the processing mode of the 4th stroke face data, then no longer given unnecessary details at this.
In addition, all have at affiliated correlative technology field know that usually the knowledgeable can both understand, on practice utilization aspect, above-mentioned picture shows that the time normally equals two to three times image time, may not be certain to equal just two times image time.Above-mentioned image time is generally 16.67 milliseconds or 13.33 milliseconds, and above-mentioned driving voltage is normally between 0 to 10 volt.
Comprehensively the above in the present embodiment, equates with the target visual legibility owing to adjust the vision legibility, so can not cause the problem of lightness out of expection on the human vision sense organ.Simultaneously, in the terminal stage of carrying out every stroke face data, be with reference time RT with the involution of picture legibility to the benchmark legibility, so carrying out next record picture data phase time, be difficult for the ghost of residual preceding unicursal face data.
In addition, first picture data and second picture data all only need 3/4 times of image time with interior time distance (OT1 and OT2 equal 3/4 times FT1 and FT3 approximately respectively), can reach target legibility B1 and B2 respectively, therefore can reduce the reaction time of 1/4 times of image time at least compared to aforementioned known embodiment.In the above-described embodiments, reference voltage is to equal 0 volt, so its pairing benchmark legibility also levels off to 0 lumen.Yet on practice utilization aspect, reference voltage only is required to be a default value and gets final product, and may not be certain to be defined as 0 volt.Another conspicuous fact is in that reference voltage is default when finishing, and the benchmark legibility also can be synchronously by default.
All in affiliated technical field, have know that usually the knowledgeable can both understand easily, reference voltage also can be applied to the initial period of carrying out every stroke face data.Simultaneously, above-mentioned driving voltage also can be modulated into the combination of a plurality of optimum visual display voltage and said reference voltage, adjusts the condition that vision legibility (as VB1 ' and VB2 ') must equal target visual legibility (as VB01 ' and VB02 ') and gets final product but only need satisfy.
In order to simplify above loaded down with trivial details narration, will be made into simple process flow figure to above disclosed method remittance below.Please continue to consult Fig. 9, it is the simple and easy driving process flow diagram that shows single picture data in the preferred embodiment of the present invention.As shown in the figure, the embodiment of the invention is to preestablish image time (as FT1), and is stored among the temporary storage 21a (step 110).Then, receive above-mentioned shows signal S1 (step 120), according to target drives voltage that the picture data in the shows signal S1 comprised and set up above-mentioned objective function (step 130), and with objective function to time integral to calculate target visual legibility (as VB01 ' and VB02 ', step 140).
Then, driving voltage is modulated into the optimum visual display voltage (as OV1 ' and OV2 ') of keeping optimization driving time (as OT1 and OT2) and the reference voltage of keeping reference time (as RT1 and RT2) (as RV, step 150), set up above-mentioned adjustment function (step 160) according to optimum visual display voltage and reference voltage, to adjust function time integral will be adjusted the vision legibility (as VB1 ' and VB2 ' to calculate, step 170), and adjustment optimum visual display voltage, reference voltage, optimization driving time and reference time, make adjustment vision legibility equal target visual legibility (step 180).At last, store optimum visual display voltage, reference voltage, optimization driving time and reference time (step 190), and show pairing picture data (step 210) to drive stored optimum visual display voltage, reference voltage, optimization driving time and reference time through above-mentioned adjustment.
All in affiliated technical field, possess know that usually the knowledgeable can both understand easily, the present invention preestablishes a schedule time (being meant image time in the present embodiment), and then carry out optimum visual display voltage, reference voltage, optimization driving time and the adjustment of reference time, use making above-mentioned adjustment vision legibility equal above-mentioned target visual legibility.Yet, on practice utilization aspect, more than the predefined schedule time also can be a picture and show the time, and this picture demonstration time is to equal at least two image times.
