Hereinafter, an electrophoretic display device and a driving method thereof according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings, wherein the same elements will be described with the same reference numerals.

1A and FIG. 1B, FIG. 1A is a schematic diagram of an electrophoretic display device 1 according to a first embodiment of the present invention, and FIG. 1B is a cross-sectional view of the line A-A of FIG. 1A.

The electrophoretic display device 1 includes a display module 11 and a driving module 12 .

The display module 11 has a display panel DP, a plurality of scanning lines S and a plurality of data lines D. The scanning lines S and the data lines D define a plurality of pixels P on the display panel DP, and each drawing The prime P corresponds to one pixel electrode 113. Here, the number of the scanning lines S is, for example, n.

The drive module 12 can be driven by an Active Matrix drive or a Passive Matrix drive. Here, the active array type driving is taken as an example. The driving module 12 is electrically connected to the pixels P of the display panel DP by the scanning lines S and the data lines D. In this embodiment, the driving module 12 includes a scan driving circuit 121 and a data driving circuit 122. The scan driving circuit 121 can output a scanning signal, and the data driving circuit 122 can output a data signal. When the scan signal outputted by the scan driving circuit 121 causes the scan lines S to be respectively turned on, the data driving circuit 122 will correspond to each column of pixels P. The data signal is transmitted to the pixel electrode 113 of each pixel P by the data lines D, so that the electrophoretic display device 1 can display an image.

As shown in FIG. 1B , the display panel DP further has a lower substrate 111 , an adhesive layer 112 , a non-volatile display material 114 , an upper substrate 115 , and a common electrode layer 116 .

The lower substrate 111 is disposed opposite to the upper substrate 115, and the pixel electrodes 113 are disposed on the lower substrate 111 and electrically connected to the data driving circuit 122 (not shown). The material of the lower substrate 111 may be resin, ceramic or glass. Here, glass is taken as an example. In addition, the upper substrate 115 may be flexible or inflexible, and may be made of resin, ceramic or glass. Herein, the material of the upper substrate 115 may be the same as or different from the material of the lower substrate 111. In addition, the non-volatile display material 114 is located between the upper substrate 115 and the lower substrate 111. The non-volatile display material 114 of the present embodiment contains an electrophoretic substance, and is, for example, a plurality of charged particles C suspended in a dielectric solution L. In this embodiment, the display panel DP may further have a receiving structure 117, and the receiving structure 117 may have a plurality of micro-cups or a plurality of microcapsules. The accommodating structure 117 of the embodiment is exemplified by a plurality of microcups, and the charged particles C are suspended in the dielectric solution L, and the charged particles C and the dielectric solution L are accommodated in the microcups. Inside.

The common electrode layer 116 is disposed between the non-volatile display material 114 and the upper substrate 115 and disposed opposite to the pixel electrodes 113 of the lower substrate 111. The material of the common electrode layer 116 and the pixel electrode 113 may be, for example, indium tin oxide (ITO), indium zinc oxide (IZO), aluminum zinc oxide (AZO), gallium zinc oxide (GZO), or oxidation. Zinc (ZnO) or the like is not limited. In addition, the adhesive layer 112 is disposed between the non-volatile display material 114 and the pixel electrodes 113. The adhesive layer 112 can adhere to the receiving structure 117 of the non-volatile display material 114 and the pixel electrodes 113. On the lower substrate 111. Among them, the resistance value of the adhesive layer 112 is relatively low, so that the electric field generated when the pixel is driven is large and the charged particles C can be quickly driven.

Therefore, when the scan signal outputted by the scan driving circuit 121 is controlled to turn on the scan lines S, the data driving signal corresponding to the data driving circuit 122 can cause a voltage difference between the common electrode layer 116 and the pixel electrode 113 to be charged. The particles C can be driven to move and reflect the ambient light, thereby presenting the color of the charged particles C or the dielectric solution L to display an image.

Hereinafter, please refer to the related drawings to explain the driving module 12 of the first embodiment. How the scanning signal drives the pixels P of the display module 11.

Please refer to FIG. 2A to FIG. 2C respectively, wherein FIG. 2A is the first implementation. In the electrophoretic display device 1 of the example, the schematic diagram of the scanning lines S of the display module 11 is shown in FIG. 2B, which is a schematic diagram of the waveform of a scanning signal, and FIG. 2C is a schematic diagram of the potential of the pixel electrode 113 of the first embodiment.

The scan signal output by the scan driving circuit 121 of the driving module 12 of this embodiment The number is input from the (1+ks) scan line to the (b+ks) scan line and is repeated for c times, where k is 0 or a positive integer, and n, b, c, and s are positive An integer, and 1≦s<n,0≦k<n,1<b<n, and when the (1+ks)th scan line to the (b+ks)th scan line are sequentially scanned, the signal is repeatedly input c After that, add k to 1, and then repeat the scanning action. Here, the value of k starts from 0, and is a positive integer such as 1, 2, 3, etc.

For example, as shown in FIG. 2A, the number n of scan lines S is, for example, 16 (the first strip is denoted by S1, ... the 16th strip is denoted by S16), and is respectively connected to the display panel DP. The scan lines S are divided into a plurality of regions (for example, four regions), and each region has, for example, four scan lines (b=4), and is respectively S1~S4, S5~S8, S9~S12, and S13~. S16. In addition, in the embodiment, c is, for example, 2, indicating that the scanning signal is repeatedly input to the area twice. In addition, s is not greater than b, ie s≦b. Here, s is, for example, 4, indicating that after a certain area ends scanning, four scanning lines are moved downward, and therefore, s=b=4. However, in other embodiments, s and b may not be equal, for example, s=3, indicating that after scanning for a certain area, only three scanning lines are moved down. Therefore, the above numbers of n, b, c, and s are merely examples, and the designer can of course apply the concepts of the present invention to different numbers of n, b, c, s.

It can be seen from the above that when k=0, the scanning signal outputted by the scan driving circuit 121 is sequentially input by the first scanning line S1 (1+0×4) and turned on to the fourth scanning line S4 (4+0×4). At this time, the data signal is input to the pixel electrodes 113 corresponding to the scan lines S1 to S4. In the prior art, the scan signal continues to output and turn on the fifth scan line S5 and the sixth scan line S6..., however, the fifth scan line S5 is not turned on in this embodiment, but the scan signal is output again. The first scanning line S1 is sequentially turned on to the fourth scanning line S4. At this time, the data signals are again input to the pixel electrodes 113 corresponding to the scanning lines S1 to S4. In other words, the scan driving circuit 121 outputs a scan signal from the first scan line S1 to the fourth scan line S4, and then repeatedly outputs a scan signal to the first scan line S1 to the fourth scan line S4 (ie, c) =2).

Next, 0(k) is incremented by 1, so that when k=1 is new, the scan driving circuit 121 The output scan signal is sequentially input by the fifth scan line S5 (1+1×4) and turned on to the eighth scan line S8 (4+1×4). At this time, the data signal is input to the scan lines S5~ S8 corresponds to the pixel electrode 113. Thereafter, the scan driving circuit 121 does not output the scan signal to the ninth scan line S9, but the output scan signal is sequentially turned on by the fifth scan line S5 to the eighth scan line S8. At this time, the data signal is again input to the pixel electrodes 113 corresponding to the scan lines S5 to S8. In other words, the scan driving circuit 121 outputs the scan signal to turn on the fifth scan line S5 to the eighth scan line S8, and then repeatedly outputs a scan signal to the fifth scan line S5 to the eighth scan line S8 (c=2). ). Then 1(k) is added to 1, so that the new k=2, the new k=3, and the repeated scans are repeated, and will not be described again.

Therefore, within a frame time, the scan lines S are sequentially scanned. The driving and opening sequence of the driving circuit 121 is: S1~S4, S1~S4, S5~S8, S5~S8, S9~S12, S9~S12, S13~S16 and S13~S16. Taking 60Hz as an example, the period of the conventional scanning signal is 1/60 second (the frame time is 1/60 second), so for each scanning line, 1/60 second will be turned on once (corresponding to this time) The data signal is input to the pixel electrode), but the pixel electrodes of adjacent pixels may cause mutual coupling and interference, thereby affecting the potential of the pixel electrode, so that the charged particle C cannot be correctly moved to the proper position. However, in the case where the frame time does not change in this embodiment, as shown in FIG. 2B, the scanning period T of the scanning signal is 1 ÷ (60 × n / b) = 1 ÷ (60 × 16 / 4) = 1 / 240 seconds, 3 times faster than the conventional technology, so compared with the conventional, although the adjacent pixel electrodes will still interfere with each other, as shown in FIG. 2C, the pixel electrode 113 of the pixel P can be 1/240. The second is input by the data voltage once, and can be input twice in one frame time, so that the potential comparison of the pixel electrodes 113 can be maintained, thereby improving the signal coupling interference between the two adjacent pixel electrodes. The display shows poor quality conditions.

However, in the above scanning process, the corresponding drawing of the first scanning line of the next zone The prime electrode 113 still interferes with the pixel electrode 113 corresponding to the last scan line of the previous region (for example, S5 affects S4, S9 affects S8, and S13 affects S12), and therefore, the signal interference problem of the adjacent pixel electrode 113 is still caused. A problem of bright and dark stripes is produced at the junction of the two zones.

In order to solve this problem, please refer to FIG. 3A , which is a schematic diagram of partitioning of the scan lines S of the display module 11 a according to the second embodiment of the present invention.

The same as above, the number n of S of the scanning lines is, for example, 16 pieces. It is divided into 4 zones, each zone has 4 scan lines (b=4). In addition, in the present embodiment, c is, for example, 2, indicating that the scanning signal is input twice, and s is, for example, 2, indicating that after one area ends scanning, two scanning lines are moved downward, and therefore, s<b. The display module 11a of the embodiment may further have a plurality of first dummy scan lines and a plurality of second dummy scan lines, and the number of the first dummy scan lines and the second dummy scan lines is equal to (bs)=2 Therefore, as shown in FIG. 3A, the codes of the first virtual scan lines are DS11 and DS12, respectively, and the codes of the second virtual scan lines are DS21 and DS22, respectively. Of course, when s and b are changed, the number of the first virtual scan lines and the second virtual scan lines also changes.

Therefore, in the second embodiment, when k=0, the scan signal is input first. Before the scanning line S1, the scanning signal first inputs the first virtual scanning lines DS11 and DS12 in sequence, and then sequentially inputs and turns on the first scanning line S1 and the second scanning line S2 (s=2). Thereafter, the scan driving circuit does not output the scan signal to the third scan line S3, but outputs the scan signal again to sequentially input the first dummy scan line DS11 to the second scan line S2. In other words, the scan driving circuit outputs the scan signal from the first dummy scan lines DS11, DS12 to the first scan line S1 and the second scan line S2, and then repeats the first dummy scan lines DS11, DS12, and the first strip. The scanning line S1 and the second scanning line S2 are output once (c=2). At this time, the first scanning line S1 and the second scanning line S2 are turned on twice.

Then, the scan signal output by the scan driving circuit is determined by the first scan line S1 (1+0×2) is sequentially input and turned on to the fourth scanning line S4 (4+0×2), after which the scan driving circuit outputs the scanning signal again from the first scanning line S1 to the fourth Scan line S4. In other words, after the scan driving circuit outputs the scan signal to turn on the first scan line S1 to the fourth scan line S4, the scan is repeated for the first scan line S1 to the fourth scan line S4 (c=2). After that, the value of k is sequentially added to 1... so that the new k=1, 2, 3...6, and the repeated scanning situation can be deduced.

When k=7, the scan signal output by the scan driver circuit is scanned by the fifteenth The line S15 (1+7×2) is sequentially input and turned on to the sixteenth scanning line S16. Since (b+ks)=(4+7×2)=18>16(n), the scanning signal is input. After the sixteenth scan line S16, the second dummy scan lines DS21 and DS22 are sequentially input. In other words, since (b+ks)>n, the scan drive power After the last scan line is turned on (S16), the second dummy scan lines DS21 and DS22 are turned on, and the fifteenth scan line S15, the sixteenth scan line S16, and the second dummy scan line DS21 are repeated. The DS22 outputs once (c=2).

Therefore, within one frame time, the scan lines and the virtual scan lines are sequentially scanned. The order of driving and starting of the dynamic circuit is: DS11~S2, DS11~S2, S1~S4, S1~S4, ...S13~S16, S13~S16, S15~DS22, S15~DS22. Therefore, taking 60 Hz as an example, in the case where the frame time is constant, the scanning period of a certain scanning line is 1/240 seconds, which is three times faster than the conventional technique, compared with the conventional one, although The adjacent pixel electrodes will still interfere with each other, but as shown in FIG. 3B, the pixel electrode 113 of the pixel P can be input to the data voltage once in 1/240 seconds, and can be input four times in one frame time. Therefore, it is possible to improve the poor display quality caused by signal coupling interference between two adjacent pixel electrodes. In addition, since the scanning of one area is completed, the two scanning lines are moved downward and the two scanning lines of the previous area are turned on and the input voltage voltage is input to the pixel electrode 113, so that the first implementation can be improved. In the example, the pixel electrode 113 corresponding to the first scan line of the next region interferes with the pixel electrode 113 corresponding to the last scan line of the previous region, thereby improving the problem of bright and dark stripes between the two regions.

In addition, please refer to FIG. 2A to FIG. 4B, wherein FIG. 4A and FIG. 4B are divided.

In one embodiment, s = b, in another embodiment, s < b. In addition, Yu Yu In the step of outputting the scan signal by the driving module, when the scan signal is input to a scan line, the drive module can further output a data signal, and input the corresponding pixel electrodes through the data lines. In addition, as shown in FIG. 3A, the display module 11a may further have a plurality of first virtual scan lines and a plurality of second lines. a virtual scan line, the number of the first virtual scan lines or the second virtual scan lines is (bs), and as shown in FIG. 4B, when k=0, step S02 is performed: the scan signal is input first. Before the scan lines, the scan signals are sequentially input to the first virtual scan lines, and then the first scan lines are sequentially input to the sth scan lines. In addition, when (b+ks)>n, step S03 is performed: after the scan signal is input to the nth scan line, the scan signal is sequentially input to the second dummy scan lines.

Further, other technical features of the driving method of the electrophoretic display device have been described in detail above and will not be described again.

Therefore, compared with the conventional ones, although the adjacent pixel electrodes still interfere with each other, the data voltage of the data line can input the pixel electrodes of the pixels in a short time, and the frame time can be The input data voltage is applied several times, so that the potential of the pixel electrode can be easily maintained at a certain value so that the electrophoretic substance can be driven to reach the position to correctly display the image.
