Need to prove that in the foregoing description, the type of drive of pixel A is: wash black → whiten → write GTG, the type of drive of pixel B is: whiten → wash black → write GTG; But the present invention is as limit, for example the situation shown in Fig. 2 B.
See also Fig. 2 B; Its show electrophoretic display device (EPD) 10 in a certain operating cycle shared current potential Vcom and offer pixel A and another sequential chart of the pixel potential of B; And in the operating cycle, gate lines G L (n-1)～GL (n+1) is enabled so that each pixel A and the B corresponding person from data line DL (m-1)～DL (m+1) receives pixel potential in regular turn.Among Fig. 2 B, the type of drive of pixel A is: whiten → wash black → write GTG, the type of drive of pixel B is: wash black → whiten → write GTG.
Particularly; In the period of time T a in operating cycle; The shared current potential Vcom that offers pixel A and pixel B be high level for example+15V; The pixel potential that offers pixel A be high level for example+15V and equate with shared current potential Vcom so that pixel A to keep its display optical state constant, the pixel potential that offers pixel B be low level for example-15V with pixel A is washed black operation make the pixel B trend show extreme black light learn state for example the GTG value be 0.
In the period of time T b in operating cycle; The shared current potential Vcom that offers pixel A and pixel B change into low level for example-15V; The pixel potential that offers pixel A be maintained high level and with the different so that pixel A of shared current potential Vcom carry out whiten operation so that make the pixel A trend show extreme white light learn state for example the GTG value be 255, the pixel potential that offers pixel B change into high level for example+15V makes the pixel B trend show that extreme white light learns state pixel B is whitened operation.
In the period of time T c in operating cycle; The shared current potential Vcom that offers pixel A and pixel B changes into high level, the pixel potential that offers pixel A change into low level for example-15V and wash black operation with the different so that pixel A of shared current potential Vcom and then make the pixel A trend show that extreme black light learns state; Moreover; Make pixel B carry out the GTG write operation with trend display-object optical states and then demonstration gray scale image; GTG value and extreme white light in that the GTG value of this each pixel B is learned state between extreme black light are learned between the GTG value of state, and for example the GTG value is more than or equal to GTG value 0 and smaller or equal to GTG value 255.In addition, after the period of time T c in operating cycle, will make pixel A carry out the GTG write operation with trend display-object optical states and then demonstration gray scale image.
In the above embodiment of the present invention; Through pixel A is designed and adopts respectively different type of drive with the spatial arrangement of pixel B; Therefore when electrophoretic display device (EPD) 10 makes charged particle mobile slack-off because of illumination ageing; Adopt the type of drive shown in Fig. 2 A will make that the show state of pixel A is white partially and show state pixel B can be black partially, and adopt the type of drive shown in Fig. 2 B will make the black partially and pixel B of the show state of pixel A the show state meeting partially in vain, like this; Utilize the whole image that on average can make on the space tangible color lump can not occur, that is the color lump non-uniform phenomenon that exists in the prior art can be well solved.
Certainly; Utilize average on the space except above-mentioned; Also can further utilize the temporal purpose of on average reaching the color lump homogenizing; For example shown in Fig. 2 C; In adjacent two operating cycle P1 of electrophoretic display device (EPD) 10 and the operating cycle P1 formerly among the P2 to pixel A adopt T1 time cycle wash-in black → T2 whiten in the time cycle → write GTG type of drive and to pixel B adopt T2 whiten in the time cycle → T3 time cycle wash-in deceive → writes the type of drive (being similar to the type of drive shown in Fig. 2 A) of GTG, and in the operating cycle P2 of back to pixel A adopt T5 whiten in the time cycle → T6 time cycle wash-in deceive → write GTG type of drive and to pixel B employing T4 time cycle wash-in deceive → T5 whitens → writes the type of drive (being similar to the type of drive shown in Fig. 2 B) of GTG in the time cycle; Or shown in Fig. 2 D; In adjacent two operating cycle P1 of electrophoretic display device (EPD) 10 and the operating cycle P1 formerly among the P2 to pixel A adopt Tb whiten in the time cycle → Tc time cycle wash-in deceive → write GTG type of drive and to pixel B adopt Ta time cycle wash-in black → Tb whitens → writes the type of drive (being similar to the type of drive shown in Fig. 2 B) of GTG in the time cycle, and in the operating cycle P2 of back to pixel A adopt Td time cycle wash-in black → Te whiten in the time cycle → write GTG type of drive and to pixel B employing Te whiten in the time cycle → Tf time cycle wash-in deceive → writes the type of drive (being similar to the type of drive shown in Fig. 2 A) of GTG.
In addition; Also can only adopt temporal average and the purpose of on average reaching the color lump homogenizing on the non-space; Particularly, in a certain operating cycle in adjacent two operating cycles of electrophoretic display device (EPD) 10, though pixel A or pixel B all adopt wash black → whiten → write the type of drive of GTG; And in another operating cycle, then all adopt whiten → wash black → write the type of drive of GTG.
In addition; What also need explain is, in the above embodiment of the present invention, the shared current potential Vcom that offers pixel A and pixel B is along with the switching of the time cycle in the operating cycle changes; With the charged particle in the electrophoresis showed layer bigger driving force is provided; But the present invention is not limited to this, for example, also can share current potential Vcom and be set to steady state value.Moreover; In the driving process of pixel A and pixel B; Owing to be electrically coupled on the same data line with the pixel A in the delegation and pixel B among Fig. 1, so data line need constantly carry out the current potential switching to provide different pixel potential to pixel A and pixel B, makes that power consumption can be bigger.So, for further realizing purpose of power saving, pixel A and pixel B can adopt electric connection mode as shown in Figure 3, that is the pixel A in the same row receives pixel potential with the electrical respectively coupling of pixel B to different data line.
In addition, the electrophoretic display device (EPD) 10 that the above embodiment of the present invention relates to can be microcapsule-type electrophoretic display device (EPD) or little glass of type electrophoretic display device (EPD), but the present invention is not as limit.Moreover the display drive method that the embodiment of the invention proposes is not limited to be useful in electrophoretic display device (EPD) 10, also also applicable to the bistable display of other type.
In sum; The embodiment of the invention is black and whiten operation through each pixel of bistable display being carried out washing of ad hoc fashion; Make that the aging color lump that occurs spatially and/or on the time averages out after bistable display is because of illumination in the prior art; Like this then can solve the color lump non-uniform phenomenon that occurs after the illumination in the prior art, promote image displaying quality.
Though the present invention discloses as above with preferred embodiment; Right its is not in order to limit the present invention; Any those skilled in the art; Do not breaking away from the spirit and scope of the present invention, when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking appended the claim scope person of defining.
