Embodiment
Hereinafter with reference to correlative type, a kind of display panels and liquid crystal indicator according to preferred embodiment of the present invention are described, wherein identical element will be illustrated with identical reference marks.
Please refer to shown in Fig. 1 the schematic diagram of its a kind of liquid crystal indicator 1 that is preferred embodiment of the present invention.
Driver module and display panels 11 are electrically connected, and can drive display panels 11 to show an image frame.Wherein, driver module can be electrically connected with display panels 11 by multiple sweep traces and multiple data line (figure does not show).Driver module can comprise a sequential control circuit (T-con), a data drive circuit (data driver) and scan driving circuit (scan driver) (figure does not show).Wherein, the image frame that driver module drives display panels 11 to show for example can be a long-time picture (for example a couple of days all shows that same image is motionless) showing, and for example can be a black and white gridiron pattern picture.As shown in Figure 2, black and white gridiron pattern picture has at least one black square district B and at least one white square district W.In this, to there is multiple staggered black square district B and multiple white squares district W as example.
Below, will describe in detail with an embodiment, how in time the present invention adjustment System common voltage value, to reduce or to improve liquid crystal indicator after long-time demonstration one image frame, and image branding (image residue) phenomenon that show image occurs.
Please refer to shown in Fig. 3 the steps flow chart schematic diagram of its a kind of method that reduces liquid crystal indicator 1 image branding that is preferred embodiment of the present invention.
The method of minimizing liquid crystal indicator image branding of the present invention is to coordinate with a display panels 11, and can comprise step S01～step S03.But, before carrying out step S01, need first carry out some and measure, to understand the characteristic of display panels 11, recycle this characteristic and carry out above-mentioned steps.
The long-time image frame (being the black and white gridiron pattern picture of Fig. 2) showing of display panels 11 can easily there is afterwards the former of image branding (image residue) because, when lighting black and white gridiron pattern picture a period of time again when switchback one grey screen, in under normal circumstances, originally black square district B and white square district W should show grey, the brightness that black square district B but occurs becomes brighter (ash not) on the contrary, and the brightness of white square district W becomes darker on the contrary, therefore cause the brightness inequality between black square district B and the white square district W in display screen, make display screen still show light chessboard pattern.Therefore, before carrying out above-mentioned steps, need first understand respectively black and white gridiron pattern picture and be lit a period of time again after switchback grey screen, the trend that black square district B and white square district W brightness change, using the foundation as subsequent drive module controls.
After measuring, a black square district B of black and white gridiron pattern picture and a white square district W are respectively to having one first brightness change curve and one second brightness change curve.Wherein, obtaining of the first brightness change curve and the second brightness change curve, first show a gray scale picture and measure respectively the gray scale intensities of black square district B and the gray scale intensities of white square district W, then, after switching to black and white gridiron pattern picture a period of time, switch to again a grey screen and measure respectively black square district B gray scale intensities and and the gray scale intensities of white square district W, and compare with the brightness of first step, obtain by this first brightness change curve of black square district B and the second brightness change curve of white square district W.In the present embodiment, a direct current residual voltage (the Residue DC Voltage that the first brightness change curve is corresponding with black square district B, RDC) there is similar variation tendency, and the second brightness change curve direct current residual voltage corresponding with white square district W has similar variation tendency, that is to say that the brightness variation in direct current residual voltage and each lattice district has positive correlation.In addition, the gray-scale value of the black square district B of the present embodiment is a lowest gray value (take 0 gray scale as example) of display panels 11, and the gray-scale value of white square district W is the highest gray-scale value (take 255 gray scales as example) of display panels 11.Certainly in other enforcement aspect, the gray-scale value of black square district B also can be the highest gray-scale value of display panel, and white square district W also can be lowest gray value.In addition, the gray-scale value of grey screen is between the highest gray scale and minimum gray scale of display panels 11.In this, the gray-scale value of grey screen is take 128 gray scales as example.
Please refer to shown in Fig. 4, it is the first brightness change curve L1 corresponding to black square of the present invention district B and white square district W difference and the schematic diagram of the second brightness change curve L2.Wherein, ordinate is brightness, and abscissa is time (second).
By finding in Fig. 4, the first brightness change curve L1 of the black square district B of the present embodiment is greatly in the time of 175 seconds time, and brightness curve starts fast rise, but after exceeding 230 seconds in the time, the brightness of black square district B changes little (having approached full closing).In addition, the brightness of the second brightness change curve L2 of white square district W is to start rising after 175 seconds time, and in the time that the time continues to increase, its brightness still increases constantly.Special one carries, and the first brightness change curve L1 of the black square district B of the present embodiment has the fast-changing characteristic of brightness, and the second brightness change curve L2 of white square district W has the characteristic of brightness rising.But, for example, under the characteristic of different materials, the light characteristic of the black square district B of liquid crystal indicator 1 and white square district W may have contrary situation, that is also may correspond to the second brightness change curve L2 by black square district B, and there is the characteristic of brightness rising, and white square district W corresponds to the first brightness change curve L1, and there is the zooming characteristic of brightness, be not limited in this.
Then, start to carry out image branding improvement method of the present invention, as shown in Figure 3, the step S01 of the method for minimizing liquid crystal indicator 1 image branding of the present invention is: drive display panels 11 show image pictures, wherein, black square district B and white square district W are respectively to having one without the residual common voltage value of direct current (optimised common voltage).In this, be display panels 11 without the residual common voltage value of direct current, under ideal state during without direct current residual voltage, the common voltage value that display panels 11 has.In addition, black square district B for example has one first without the residual common voltage value of direct current, and white square district for example has one second without the residual common voltage value of direct current.Wherein, the common voltage value while referring to display frame flicker (flicker) optimization (less or do not have) without the residual common voltage value of direct current.In this, flicker optimization not only refers to there is no scintillation completely, experiences less than scintillation but comprise for example human eye.Wherein, by adjusting the system common voltage of display panels 11, allow the grayscale voltage of opposed polarity drive when display panel and (for example draw the grayscale voltage of black flour or the grayscale voltage of white picture), there is not scintillation in the brightness of display frame, now adjusted system common voltage is called without the residual common voltage value of direct current.In this, be a preferred values without the residual common voltage value of direct current, a not optimum value.Demander is when obtaining the better common voltage value of better common voltage value because of assisting of experience or measuring instrument.In the present embodiment, the first absolute value without the residual common voltage value of direct current and the second difference without the residual common voltage value of direct current corresponding to white square district W that black square district B is corresponding for example, between (150mv) between 10 millivolts (mv) and 1 volt.In addition, then explanation is a bit, according to the convention of this area, and when the predetermined system common voltage of liquid crystal indicator 1 drives display panels 11 with 128 gray scales, the scintillation of display frame common voltage value hour, and be certain value.
Obtain black square district B first without the residual common voltage value of direct current and white square district second without after the residual common voltage value of direct current, then, carry out step S02: in a very first time point t1, system common voltage is adjusted in these brightness change curves, and rate of curve the greater is corresponding without the residual common voltage value of direct current.In the present embodiment, as shown in Figure 4, in comparison, these brightness change curves are the first brightness change curve L1 of black square district B and the second brightness change curve L2 of white square district W.Wherein, rate of curve the greater represents when brightness curve starts to have significant change, to have larger slope person.In the present embodiment, rate of curve the greater is in black white reverse region in (region A), the first brightness change curve L1 of the fast-changing black square of brightness curve district B, and rate of curve smaller is slowly the second brightness change curve L2 of the white square district W of variation of brightness curve.Therefore, driver module in very first time point t1(for example in the 175th second of Fig. 4) while driving display panels 11, the first brightness change curve L1 corresponding first that the system common voltage of liquid crystal indicator 1 is adjusted into black square district B is without the residual common voltage value of direct current.
Then, then carry out step S03: in one second time point t2, system common voltage is adjusted in these brightness change curves, rate of curve smaller is corresponding without the residual common voltage value of direct current.In this, as shown in Figure 4, rate of curve smaller, for brightness curve changes slower person, is the second brightness change curve L2 of white square district W.Therefore, driver module can be in the time that the second time point t2 drives display panels 11, and the second brightness change curve L2 corresponding second that the system common voltage of liquid crystal indicator 1 is adjusted into white square district W is without the residual common voltage value of direct current.
Because the first absolute value without the residual common voltage value of direct current and the second difference without the residual common voltage value of direct current corresponding to white square district W corresponding to black square of the present invention district B is between between 10 millivolts (mv) and 1 volt, therefore in the modulation of the system common voltage of step S01 and step S02, the mobility scale of system common voltage is still between between 10 millivolts and 1 volt.In addition, the magnitude of voltage after this system common voltage modulation except can be black square district B without the residual common voltage value of direct current or white square district W without the residual common voltage value of direct current, also can fall between, in addition restriction especially.
In addition, please refer to shown in Fig. 5 another steps flow chart schematic diagram of its a kind of method that reduces liquid crystal indicator 1 image branding that is preferred embodiment of the present invention.
As shown in Figure 5, the method for minimizing liquid crystal indicator 1 image branding more can comprise step S04 and step S05.
In step S04, in one the 3rd time point t3, system common voltage is adjusted in these brightness change curves, rate of curve the greater is corresponding without the residual common voltage value of direct current.In this, driver module, in the time that the 3rd time point t3 drives display panels 11, is adjusted into system common voltage the first brightness change curve L1 corresponding first of black square district B again without the residual common voltage value of direct current.
Then, in step S05, in one the 4th time point t4, system common voltage is adjusted in these brightness change curves, rate of curve smaller is corresponding without the residual common voltage value of direct current.In this, driver module, in the time that the 4th time point t4 drives display panels 11, is adjusted into system common voltage the second brightness change curve L2 corresponding second of white square district W again without the residual common voltage value of direct current.
In other words, step S04 and step S05 are repeating step S02 and step S03.So repeatedly adjust the system common voltage that drives liquid crystal indicator 1, to drive display panels 11 to show black and white gridiron pattern picture.
Please refer to shown in Fig. 6, it is for the present invention is in the time that different time is adjusted the system common voltage of liquid crystal indicator 1, the brightness change curve schematic diagram of the black square district B of display frame and white square district W.Wherein, V
cOM1for the black square district B corresponding first of the present embodiment is without the residual common voltage value of direct current, and V
cOM2for the white square district W corresponding second of the present embodiment is without the residual common voltage value of direct current.
As shown in Figure 6, in the process of above-mentioned driving, modulation, the time interval of very first time point t1 and the second time point t2 is T1, and the time interval of the second time point t2 and the 3rd time point t3 is T2, by that analogy.Wherein, time interval T1～time interval T4 can have different time, and each time interval (T1～T4) can be respectively between 1 second and 3600(1 hour) between.
Shown in Fig. 4, can be learnt by Fig. 4, due to the brightness variation of black square district B and the brightness variation tendency difference of white square district W, therefore cause the brightness of black square district B and white square district W to change unequal, thereby can cause the branding phenomenon of image, therefore, the present invention, by the system common voltage of different time points time modulation liquid crystal indicator 1, approaches the brightness variation tendency of black square district B and white square district B.In addition, as shown in Figure 6, in the time of time point t1, due to the first brightness change curve L1 fast rise in black square district, therefore system common voltage value is adjusted into the first brightness change curve L1 corresponding first without the residual common voltage value of direct current V
cOM1, therefore, after time point t1, the brightness of black square district B (curve L1) almost remains unchanged, and the brightness of white square district W (curve L2) slowly increases; In addition, in the time of time point t2, then the second brightness change curve L2 corresponding second that system common voltage value is adjusted into white square district W is without the residual common voltage value of direct current V
cOM2, now, after time point t2, the brightness fast rise of black square district B (curve L1), and white square district W maintains previous brightness (curve L2 almost remains unchanged); In addition, after a period of time spacing T2, in the time of time point t3, then system common voltage value is adjusted into the corresponding V of the first brightness change curve L1
cOM1, now, after time point t3, the brightness of black square district B (curve L1) almost remains unchanged, and the brightness of white square district W (curve L2) slowly increases, and by that analogy.Repeat constantly adjustment System common voltage value, make the brightness of black square district B and white square district W change approaching.Because the brightness variation tendency of black square district B and white square district B approaches, therefore human eye just can not be experienced the luminance difference that between the two, therefore just cannot see the chessboard pattern of black and white.Wherein, the time point that Fig. 6 shows only arrives t6, does not represent that restriction system common voltage value of the present invention is only adjustable to time point t6 and just stops, but repeats sustainably to adjust.
Therefore, by time adjustment System common voltage value of the present invention, can reduce or improve liquid crystal indicator 1 after long-time demonstration one image frame, image branding (image residue) phenomenon that show image occurs.
In sum, because having a variable system common voltage according to display panels of the present invention and liquid crystal indicator, the mobility scale of this system common voltage is between between 10 millivolts and 1 volt.By this, make display panels of the present invention and liquid crystal indicator there is the system voltage value of variation and be different from prior art, and can adjust its variation value in response to the image frame showing.In one embodiment of this invention, can be adjusted in these brightness change curves in the name a person for a particular job system common voltage of liquid crystal indicator of a very first time, rate of curve the greater is corresponding without the residual common voltage value of direct current, and in one second time point, system common voltage is adjusted in these brightness change curves, and rate of curve smaller is corresponding without the residual common voltage value of direct current.In addition.Magnitude of voltage after this system common voltage modulation except can be black square district without the residual common voltage value of direct current or white square district without the residual common voltage value of direct current, also can fall between.Thus, by the modulation of system common voltage, and mobility scale is between between 10 millivolts and 1 volt, make liquid crystal indicator of the present invention can reduce or improve liquid crystal indicator after long-time demonstration one image frame, image branding (image residue) phenomenon that show image occurs.
The foregoing is only illustrative, but not be restricted person.Anyly do not depart from spirit of the present invention and category, and equivalent modifications or change that it is carried out all should be contained in claim scope.
