The present invention relates to electronic paper, in particular, to an electronic paper panel driving method and an electronic paper panel driving device. More specifically, the entire screen is not erased at once, but addressed after sequentially erasing each scan line.

BACKGROUND ART Conventionally, an electronic paper device using an electrophoretic method, an electrochromic method, a thermal method, a two-color particle rotation method and the like has been proposed as an image display device replacing a liquid crystal (LCD). Such an electronic paper device is considered to be a technology that can be used in the next generation of inexpensive image display devices because of the advantages of having a wider viewing angle closer to a normal printed matter, smaller power consumption, and a memory function than LCDs. Development into terminal image displays, electronic papers, and the like is expected.

Especially, the electrophoresis type electronic paper which microencapsulates the dispersion liquid which consists of a dispersion particle and a coloring solution, and arrange | positions it between the opposing board | substrate is proposed, and the expectation is gathering. The display incorporates a unique concept of electrophoretic ink encapsulated in the technology. As shown in FIG. 1, the capsule-type electronic paper prepares transparent microcapsules contained in a dielectric fluid in which black fine particles 40 and white fine particles 30 have a color, and then mixed with a binder 50 to form a substrate ( Positioned between the upper and lower transparent electrodes 20 inscribed in 10) and applying a positive voltage, the negatively charged ink fine particles move to the surface to display the color of the fine particles. In addition, when a negative voltage is applied, the ink particles move downward to see the color of the fluid. In this way, the characters or images are displayed.

In addition, with respect to the electrophoresis method using the above-described behavior in a solution, at least two kinds of particles having different colors and charging characteristics are enclosed between at least one transparent substrate without using a solution in recent years, and the substrate There has been proposed an electronic paper for imparting an electric field to the particles from an electrode pair consisting of electrodes formed on one or both of the electrodes, and moving the particles by coulomb force to display an image.

The cell structure of the dry electronic paper display device is shown in FIG. 2 and briefly described as follows. As shown, the structure is formed of upper and lower substrates 160 and 110 formed of plastic or glass, and transparent electrodes ITO to apply driving voltages of devices on the upper and lower substrates 160 and 110. The upper and lower electrodes 170 and 120, the partition wall 130 separating the cell from the cell, the black positive charged particles 140 and the white negative charged particles existing between the two electrodes. It consists of 150.

In the electronic paper display device having the above structure, when sufficient voltage is applied to the upper electrode 170 and the lower electrode 120, charged particles 130 and 140 charged according to the applied electrode polarity are attracted to each electrode. . For example, when-voltage is applied to the lower electrode 120 and + voltage is applied to the upper electrode 170, the black charged particles 140 positively charged by the coulomb force move toward the lower substrate 110. The charged white charged particles 150 move toward the upper substrate 160. Since the white charged particles 150 are located on the upper substrate 160 side, the white charged particles 150 appear to be white when viewed from the outside. On the contrary, when + voltage is applied to the lower electrode 120 and-voltage is applied to the upper electrode 170, the charged white charged particles 150 move toward the lower substrate 110, and the positively charged black charged particles ( 140 moves toward the upper substrate 160 to be displayed in black. Therefore, after applying a voltage so that all the cells appear white at first, only the desired cell is applied with the opposite voltage so that the cells appear black.

As such, the electronic paper displaying the image by the rotation or movement of the particles by electrophoresis reacts to the change of the cell in response to the voltage applied between the upper electrode and the lower electrode. This causes a difference in the amount and speed at which the particles are attracted.

3 illustrates a simple matrix driving method according to the prior art, and describes an operation when the driving method is applied to an electronic paper display panel in a passive matrix form. As shown in FIG. 3, a conventional simple matrix driving method is not shown, but a plurality of data lines (upper electrode lines) and scan lines (lower electrode lines) (scan lines 1 to scan line N) are configured in a matrix form. Applies a scan pulse that falls from the ground voltage to a predetermined negative voltage (-Vs) to the electronic ink display device connected to the first scan line in the plurality of data lines, and the plurality of data lines D1 configured in the display panel during the time when the scan pulse is applied. Data pulses are applied to ˜Dm) to operate the display elements. The ground voltage is applied to the remaining scan lines to which the scan pulse is not applied, and this process is performed for all scan lines.

After all display elements operate, a reset pulse having a predetermined negative voltage is applied to all data lines D1 to Dm. Electronic paper displaying an image by the movement of particles moved by a driving voltage applied between the positive electrodes has a memory effect in which particles do not move even when the voltage is turned off, so that each cell must be erased before addressing new data information. This is because it requires a step.

4A to 4C are drive waveform diagrams showing various methods of collectively erasing the full screen of an electronic paper by applying a reset pulse according to the prior art. Specifically, FIG. 4A applies reset pulses only to the scan line, FIG. 4B applies reset pulses only to the data line, and FIG. 4C collectively applies the full screen by applying reset pulses to the scan line and the data line together. It is erasing.

However, by collectively erasing the full screen of the electronic paper by applying a reset pulse to the scan line, the data line, or both the scan line and the data line, the erasing is performed over the full screen before addressing. The entire process is temporarily changed to black or white, and the overall change of the screen seriously degrades the image quality realized by the screen. Accordingly, there is an urgent need for a new driving method and driving device for erasing and addressing each cell in an electronic paper including particles having a memory effect.

Hereinafter, one preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. The invention can be better understood by the following examples, which are intended for the purpose of illustration of the invention and are not intended to limit the scope of protection defined by the appended claims.

5A to 5C show driving waveforms for the electronic paper panel driving method according to the present invention. A first preferred embodiment of the present invention as shown in FIG. 5A applies a reset pulse Vr ₁ only to a scan line. It is applied by erasing. That is, erasing the pixels of one line SCAN 1 of the plurality of scan lines. Here, erasing may be performed by applying a reset pulse Vr ₁ to the one line. In addition, a scan pulse (-Vs) is applied to the corresponding scan line SCAN 1 of the erased pixels, and a data pulse synchronized with the scan pulse -Vs to the data lines DATA 1 and 2. And (V _D ) applying and addressing.

The erasing method according to the present invention does not erase the entire screen to black or white at the same time as in the prior art, and erases pixels belonging to any one line of a plurality of scan lines and then belongs to the other one line. Erase the pixels. That is, the repetition of erasing and addressing for erasing and addressing any one of the scan lines may only erase the selected scan line, and thus, the image quality may not be degraded.

A second preferred embodiment of the present invention as shown in FIG. 5B is to erase by applying the reset pulse -Vr ₁ only to the data line. In other words, the pixels of one line SCAN 2 of the plurality of scan lines are erased. Here, erasing may be performed by applying a reset pulse (-Vr ₁ ) to the one line. In this case, the reset pulse (-Vr ₁ ) is applied by the data lines DATA 1 and 2 to scan line ( Erase the pixels of SCAN 2). In order to erase the pixels belonging to the scan line SCAN 2 by the data lines DATA 1 and 2, a reset pulse (-Vr ₁ ) must be applied to all of the data lines DATA 1 and 2. Although the cell is turned off after a scan pulse is applied (cell on) to any one scan line SCAN 1, the on state may be maintained because there is no charge movement, but any one of the plurality of scan lines There is a disadvantage in that not only the scan line SCAN 2 that is not addressed for erasing (SCAN 2) but also the scan line SCAN 1 that is already addressed are erased. Thereafter, a scan pulse (-Vs) is applied to the corresponding scan line SCAN 2 of the erased pixels, and data synchronized with the scan pulse (-Vs) to the plurality of data lines DATA 1 and 2. The process of applying and addressing the pulse V _D is as described above.

Further, a preferred degree third drive embodiment of the present invention as shown in 5c is to seven days easing by applying a reset pulse ₍₂ Vr and -Vr ₂₎ in both the scan lines and data lines. That is, erasing the pixels of one line SCAN 1 of the plurality of scan lines. Here, the seventh staging can be performed by applying a reset pulse ₍₂ Vr and -Vr ₂₎ on the one line. In addition, a scan pulse (-Vs) is applied to the corresponding scan line SCAN 1 of the erased pixels, and a data pulse synchronized with the scan pulse -Vs to the plurality of data lines DATA 1 and 2. Addressing by applying (V _D ). Here, the scan line reset pulse applied with the (SCAN 1) and data lines (DATA 1, 2) (Vr 2 and -Vr ₂₎ is seven pixels belonging to one scan line (SCAN 1) among a plurality of scan lines For erasing, only pixels of one line SCAN 1 of the plurality of scan lines can be erased by being input to only one selected scan line SCAN 1.

In the present invention, the erasing and addressing may be sequentially applied to each of the plurality of data lines and the plurality of scan lines for each scan line, and the erasing of the pixels may include scan lines and data. It is more preferably performed by applying a reset pulse to at least one of the lines. That is, not only the scan line but also the data line or the scan line and the data line may be characterized by applying a reset pulse. In this case, the reset pulse applied to the scan line and the reset pulse applied to the data line may have voltages in different directions.

In this way, the reset pulse Vr ₁ is applied with scan pulses (-Vs) and data pulses DATA 1 and 2 (on a cell) while addressing and sequentially addressing and scanning each scan line. Since it is not applied to the coarse scan line SCAN 1 but is applied to another scan line SCAN 2 other than the coarse scan line, it does not affect the charge movement of the previously addressed cell and does not affect the cell. Can remain on. The width and voltage levels of the reset pulse Vr ₁ may be such that they do not affect adjacent scan lines.

In addition, since the reset pulse Vr ₁ has a slow response time due to the characteristics of the electronic paper display device, a pulse width is wide and a high voltage level is supplied to rapidly change the state of the cell, thereby increasing the contrast and the response speed of the cell. It is more desirable to control. That is, it is more suitable that the pulse width and voltage level Vr ₁ of the reset pulse is wider and larger than the pulse width and voltage level (-Vs or V _D ) of the scan pulse or data pulse.

As shown herein, in the electronic paper panel driving apparatus including a plurality of data lines 1 and a plurality of scan lines 2 to which a driving voltage is applied, among the plurality of scan lines 2 And a scan driver 4 and a data driver 7 capable of applying a reset pulse for erasing one line of pixels. The scan driver 4 includes a scan line to which the reset pulse is applied. A scan pulse is applied to each other, and the data driver 7 applies an address of the data pulse synchronized with the scan pulse to the plurality of data lines.

Specifically, in the present invention, a plurality of data lines D1 to Dm and a scan line (Scanline 1 to Scanline N) are vertically intersected as shown in FIG. 6, and cells are present at the crossing positions. The electronic paper display panel 3 and the scan driver 4 capable of applying a reset pulse for erasing pixels belonging to any one of the plurality of scan lines 2 as shown in FIG. 7; And a data driver 7.

Here, the reset pulse may erase any one of the plurality of scan lines 2, and the scan driver 4 and the data driver 7 capable of applying the reset pulse may be one of the driving units. At least one drive unit preferably applies a reset pulse. That is, not only the scan driver 4 but also the data driver 7 or the scan driver 4 and the data driver 7 may apply the reset pulse together.

Thus, the scan driver 4 applying the reset pulse preferably erases pixels of one line of the plurality of scan lines 2 by applying a reset pulse to any one of the plurality of scan lines 2. In addition, the data driver 7 applying the reset pulse may more preferably erase the pixels of one line of the plurality of scan lines 2 by applying the reset pulses to the plurality of data lines 1.

The present invention erases the pixels belonging to any one of the plurality of scan lines 2 by using the scan driver 4 and the data driver 7 which can apply the reset pulse. Is applied by applying a scan pulse and a data pulse for each scan line applied. That is, the scan driver 4 according to the present invention applies a scan pulse for each scan line after the scan pulse is applied to any one scan line to which a reset pulse is applied, among the plurality of scan lines 2. The scan pulse is sequentially applied to another scan line to which a reset pulse is applied among the plurality of scan lines 2.

To this end, the scan driver 4 according to the present invention includes a plurality of switching means, applies a scan pulse for each scan line to which the reset pulse is applied, and the data driver 7 includes a plurality of switching means. And a plurality of driving ICs 6 which apply data pulses synchronized with the scan pulses to the plurality of data lines.

The scan driver 10 may include a pulse generator 5 for outputting a reset pulse or a scan pulse capable of erasing any one of a plurality of scan lines according to an externally input control signal, and generating the pulse. And a floating driver 6 for applying a predetermined pulse signal output from the section 5 to a new scan line that has not been erased or to a scan line that has already been reset with a reset pulse.

8 is a detailed view of the scan driver of FIG. 7. As shown here, the pulse generator 5 includes a plurality of switching means sw1 to sw3 and reset pulses Vr ₁ for erasing pixels of one of the plurality of scan lines. or Vr ₂ ) or a scan pulse (−Vs) having a predetermined voltage is output for each scan line to which the reset pulse is applied. Here, the voltage Vr ₁ is output when the reset pulse is based only on the scan driver, and the voltage Vr ₂ is output when the reset pulse is applied together with the data driver. Then, the floating driver 6 applies the predetermined pulse signal (reset pulse or scan pulse) output from the pulse generator 5 to the selected scan line among the scan lines in the floating state.

FIG. 9 is a detailed view of the driver IC 6 of the data driver 7 of FIG. 7. As shown here, the driving IC 6 is composed of a plurality of switching means SWa to SWd, and reset pulses (-Vr ₁ ) for erasing pixels of one line of the plurality of scan lines. or -Vr ₂ ) or a data pulse V _D having a predetermined voltage synchronized with the scan pulse output from the scan driver. Here, when the reset pulse is based only on the data driver, -Vr ₁ When the voltage is output and the reset pulse is applied together with the scan driver, the -Vr ₂ voltage is output to the data line 1 of the electronic paper display panel 3.

Here, the plurality of switching means provided in the pulse generator 5 and the floating driver 6 and the plurality of switching means constituting the driving IC 6 are connected to a predetermined switching control signal output from an external control unit. The control signal applied to each switching means of the floating driver 6 is basically controlled (on or off), and all the scan lines (scan line 1 to scan line N) are floated with the off switching control signal applied. In this state, the ON switching control signal is input for the selected scan line only for a predetermined time, and the predetermined pulse signal output from the pulse generator 5 is applied to the selected scan line.

The operation of the first embodiment of the present invention made up of these steps will now be described in detail with reference to FIGS.

First, a reset pulse for erasing pixels belonging to one line of a plurality of scan lines is applied, in which case erasing may be a moment when voltage is first applied to a screen, and another scan after a specific scan line is addressed. It might be erasing a line. In addition, it is preferable that any one of the scan lines to which the present invention is applied is in a floating state before the addressing signal is applied by the scan pulse and the data pulse.

Thus, the reset pulse Vr ₁ having a predetermined width and direction is applied through the scan driver 4 to make the floating scan line black or white. That is, the scan driver (4) by the SW1 of sw2, and the floating drive unit 6 of the pulse generator (5) in the on for a predetermined period of time by applying a reset pulse (Vr ₁₎ in a scan line one seven cells in a floating state Keep in the easing state. At this time, the 0V voltage GND is applied to all data lines.

Then, in order to address the cells of the scan line erased by the reset pulse Vr ₁ , a scan pulse is applied to the scan line. For example, in order to drive the cells connected to the first scan line (scan line 1), sw3 of the pulse generator 5 and SW1 of the floating driver 6 are turned on to scan the first of the floating scan lines. Only scan lines with a voltage level of -Vs are applied. Here, since the scan lines other than the selected scan line are all floating during the time when the scan pulse is applied, no voltage is applied to the unselected cells unlike the conventional manual driving method.

Simultaneously or subsequently, a data pulse synchronized with the scan pulse is applied to the plurality of data lines to drive a cell. For example, when frame data for driving a specific cell is input from the outside, each driving IC 6 of the data driver 7 outputs a data pulse for driving the cell to a data line. That is, after turning on the SWa for a predetermined time by the switching control signal input from outside off to output a V _D voltage, a data pulse to thereby turn on the SWb and SWc outputs the ground voltage (GND) having a V _D voltage level Is applied to the data line. Data pulses applied to the plurality of data lines and scan pulses applied to the first scan line are synchronized to drive cells connected to the first scan line to display predetermined data.

This process is sequentially performed from the first scan line (scan line 1) to the last scan line (scan line N). In other words, after a reset pulse for erasing cell pixels belonging to any one of the plurality of scan lines is input, a scan pulse and a data pulse synchronized with the erased scan line are applied to address the last scan. It will be done sequentially up to the line. The operation of the first embodiment as described above can be implemented on the same principle in the second and third embodiments, which are erased by both the data line, the scan line, and the data line. It is obvious to those skilled in the art.

In addition, in the present invention, since the on state is maintained because there is no charge movement even when the cell is turned off after the scan pulse is applied (cell on), the reset pulse and the reset pulse are applied. The scan pulses applied to the scanned lines may have voltages in different directions. In the same principle, it is preferable that the reset pulse and the data pulse applied to the data line to which the reset pulse is applied also have voltages in different directions.

Furthermore, in the present invention, since the scan pulse and the data pulse also have voltages in different directions, the voltage applied to the cell can be divided, so that the voltage of the driving IC can be lowered, thereby reducing the cost of the driving IC. There are advantages to it.

In the above description, it should be understood that those skilled in the present invention can only make modifications and changes to the present invention without changing the gist of the present invention as merely illustrative of a preferred embodiment of the present invention.

As described above, according to the present invention, in an electronic paper panel driving method having a plurality of data lines and a plurality of scan lines applying a driving voltage, erasing pixels of one line among the plurality of scan lines. And an addressing step of applying a scan pulse to a corresponding scan line of the erased pixels and applying a data pulse to the plurality of data lines. Can provide.

According to the present invention, it is possible to solve the problem that the entire screen temporarily turns black or white by erasing the full screen of the electronic paper before addressing as in the prior art, and increase the contrast of the panel. In addition, the screen quality can be increased by equalizing the state of cells.
