Static display drive multistable display

Abstract

The present application is a static display driving multi-stable display, comprising a timing control circuit unit, a driving circuit unit and a panel unit. The timing control circuit unit generates timing control signals. The data signal of the timing control signals comprises pixel static display header data and pixel static display waveform data. The driving circuit unit determines the pixel display voltage value of the pixel display driving signal output to the panel unit according to the pixel static display header data, and determines the pixel display driving time length of the pixel display driving signal output with the pixel display voltage value according to the pixel static display waveform data. Since the driving circuit unit only needs to determine the entire waveform of the pixel display driving signal according to the pixel static display header data and the pixel static display waveform data for each pixel electrode, the clock frequency is independent of the working count, thereby greatly reducing the amount of data to be transmitted, and a lower clock frequency can be used, thereby reducing power consumption.

Description

Technical Field

[0001] This invention relates to a display, and more particularly to a static display driven multistable display driven by a low-frequency driving method. Background Technology

[0002] Existing multistable displays, such as cholesterol liquid crystal displays (ChLCDs), exhibit bistable liquid crystal display characteristics. Therefore, these multistable displays require various voltage configurations to drive them when displaying images. For example, such a multistable display has a panel unit, where each pixel is composed of several scan electrodes and several data electrodes, and a liquid crystal layer is disposed between these line electrodes and pixel electrodes. When driving the panel unit, voltages are applied to the line electrodes and pixel electrodes, creating a specific voltage across the corresponding pixel position, causing the liquid crystal in the liquid crystal layer to rotate to a specific angle.

[0003] However, this multi-stable display requires multiple voltage configurations to drive it. Therefore, in the control signals, the data used to control the voltage configuration of each pixel needs to be transmitted through multiple bits, and multiple voltage configurations cannot be expressed with a single bit. For example, currently, the data used to control the voltage configuration is transmitted through 3 bits of data. That is, every time the voltage configuration of a pixel is changed, 3 bits of data need to be transmitted.

[0004] Furthermore, the multistable display will have a timing controller (TCON) and a driver IC. The timing controller generates a timing control signal to the driver IC, and the driver IC outputs a pixel drive signal to the plurality of line electrodes and the plurality of pixel electrodes according to the control signal, thereby driving the multistable display to display a specific image.

[0005] Generally, this timing control circuit unit has a clock output terminal (clock; clk), a display output enable control terminal (display output enable; doe), a display output ground control terminal (display output ground; dog), a digital-to-analog conversion control terminal (digital to analog; d2a), a display start signal control terminal (displaystart pulse; dsp), and several data output terminals. The clock output terminal (clk), display output enable control terminal (doe), display output ground control terminal (dog), digital-to-analog conversion control terminal (d2a), display start signal control terminal (dsp), and these data output terminals are connected to the driver circuit unit (Driver IC) to output the control signal. The frequency of the clock signal output by the clock output terminal (clk) greatly affects the overall power consumption. The higher the frequency of the clock signal, the greater the overall power consumption.

[0006] For example, consider a multistable display with a Full HD resolution of 1920×1080. When transmitting at a single data rate (SDR), 2 pixels of data are transmitted per clock cycle, meaning 2 pixels are transmitted per clock cycle. Furthermore, the transmission time (T) for each frame is set. line The time complexity is 5 milliseconds (ms). Each pixel of this multistable display requires 3 bits of data to be transmitted. Furthermore, since each pixel requires 3 bits of data to be transmitted, and the number of pixels transmitted per clock cycle is 2, the number of data output terminals is 6, calculated as 3 × 2 = 6.

[0007] Furthermore, for each pixel, multiple voltage configurations are required to complete the output within a frame. Therefore, the voltage waveform needs to be adjusted within a frame. For example, there are multiple duty periods within a frame, and the total number of duty periods within a frame is called the duty count. For instance, the duty count is adjusted as needed and can be set to 64, typically in powers of 2. When the voltage configuration required for each duty period is different, 3 bits of data need to be sent again. Therefore, the more duty periods there are, the more times data needs to be transmitted.

[0008] The clock rate of this multistable display can be calculated using the following formula:

[0009]

[0010] The resolution is 1920. The number of pixels transmitted per clock cycle is 2 in SDR mode. The hold time is set to 1. The duty count can be adjusted as needed and can be set to 64. The transmission time (T) line The value is 5 milliseconds (ms). Substituting the above figures into the formula yields the following Table 1.

[0011]

[0012] Table 1

[0013] As shown in Table 1, under Full HD resolution, the clock rate of this multistable display is quite high because the clock rate is related to the duty count. This results in high power consumption and rapid power consumption. Summary of the Invention

[0014] Given that existing multistable displays have relatively high clock rates, resulting in high power consumption and rapid battery drain, this invention provides a static display driver for multistable displays to reduce the clock rate of the multistable display, thereby reducing power consumption.

[0015] The static display driver multistable display includes a timing control circuit unit (TCON), a driver circuit unit (Driver IC), and a panel unit (Panel).

[0016] The timing control circuit unit generates a timing control signal. The drive circuit unit is connected to the timing control circuit unit and receives the timing control signal. The panel unit is connected to the drive circuit unit.

[0017] The timing control signal includes a data signal, which contains pixel static display header data and pixel static display waveform data. The driving circuit unit determines a pixel display voltage value of the pixel display driving signal output to the panel unit based on the pixel static display header data, and the driving circuit unit determines a pixel display driving duration of the pixel display driving signal with the pixel display voltage value based on the pixel static display waveform data.

[0018] Because the driving circuit unit determines the pixel display voltage value of the pixel display driving signal output to the panel unit based on the pixel static display header data, and determines the pixel display driving duration of the pixel display driving signal with the pixel display voltage value based on the pixel static display waveform data, the driving circuit unit only needs to determine the entire waveform of the pixel display driving signal for each pixel electrode based on the pixel static display header data and the pixel static display waveform data. There is no need to readjust the voltage waveform by providing a new voltage value during voltage adjustment. In other words, the clock rate is independent of the duty count. This significantly reduces the amount of data that needs to be transmitted, and allows for the use of a lower clock rate to transmit the same amount of data in the same amount of time, thereby reducing power consumption.

[0061] Please see Figure 1 As shown, the static display driving multistable display of the present invention includes a timing control circuit unit 10, a driving circuit unit 20, and a panel unit 30.

[0062] The timing control circuit unit 10 generates a timing control signal. The drive circuit unit 20 is connected to the timing control circuit unit 10 and receives the timing control signal. The panel unit 30 is connected to the drive circuit unit 20 and receives the timing control signal.

[0063] Please see Figure 2 The diagram shows the structure of the panel unit 30 of the multi-stable display. The panel unit 30 is a passive matrix composed of a plurality of intersecting pixel electrodes 31 (rows 1 to n) and a plurality of line electrodes 32 (columns 1 to m), with each pixel electrode 31 and each line electrode 32 forming a pixel at their intersection. In other words, each pixel has a corresponding pixel electrode 31 and a corresponding line electrode 32. Figure 2 In this display panel unit 30, there are n pixel electrodes 31 and m line electrodes 32. The panel unit 30 is driven by the driving circuit unit 20 outputting pixel driving signals to the pixel electrodes 31 and line driving signals to the line electrodes 32. For example, the driving circuit unit 20 sequentially outputs pixel driving signals and line driving signals to the pixel electrodes 31 and the line electrodes 32 in a scanning manner.

[0064] Please see Figure 3A and Figure 3BAs shown, the timing control signal includes a data signal 11, and the data signal 11 includes pixel static display header data 111 and pixel static display waveform data 112. The driving circuit unit 20 determines a pixel display voltage value for a pixel display driving signal output to the panel unit 30 based on the pixel static display header data 111, and the driving circuit unit 20 determines a pixel display driving duration for outputting the pixel display driving signal with the pixel display voltage value based on the pixel static display waveform data 112. In this embodiment, the pixel display driving signal is the pixel driving signal output by the driving circuit unit 20 to the plurality of pixel electrodes 31.

[0065] Since the driving circuit unit 20 determines the pixel display voltage value of the pixel display driving signal output to the panel unit 30 based on the pixel static display header data 111, and determines the pixel display driving duration of the pixel display driving signal with the pixel display voltage value based on the pixel static display waveform data 112, the driving circuit unit 20 only needs to determine the entire waveform of the pixel display driving signal for each pixel electrode based on the pixel static display header data 111 and the pixel static display waveform data 112, without needing to readjust the voltage waveform by applying a new voltage during voltage adjustment. In other words, the clock rate is independent of the duty count, which significantly reduces the amount of data that needs to be transmitted, and allows for the use of a lower clock rate to transmit the same amount of data in the same amount of time, thereby reducing power consumption.

[0066] Furthermore, please refer to Figure 4A and Figure 4B As shown, the data signal 11 also includes pixel clear header data 113. The driving circuit unit 20 determines a pixel clear driving signal to be output to the panel unit 30 based on the pixel clear header data 113. Generally, the pixel clear driving signal is a driving signal with a fixed waveform. Therefore, the driving circuit unit 20 can determine the pixel clear voltage value of the pixel clear driving signal based on the data in the pixel clear header data 113, and then output the pixel clear driving signal with a fixed waveform.

[0067] In addition, please see Figure 5A and Figure 5BAs shown, the data signal 11 also includes pixel clear header data 113 and pixel lateral spiral arrangement (Uniform Lying Helix; ULH) header data 115. The driving circuit unit 20 determines the pixel clear drive signal output to the panel unit 30 based on the pixel clear header data 113, and the driving circuit unit 20 determines the pixel ULH drive signal output to the panel unit 30 based on the pixel ULH header data 115. Typically, the pixel clear drive signal and the pixel ULH drive signal are drive signals with fixed waveforms. Therefore, the driving circuit unit 20 can determine the pixel clear voltage value of the pixel clear drive signal based on the data in the pixel clear header data 113, and then output the pixel clear drive signal with a fixed waveform. Furthermore, the driving circuit unit 20 can determine the pixel ULH voltage value of the pixel ULH drive signal based on the data in the pixel ULH header data 115, and then output the pixel ULH drive signal with a fixed waveform.

[0068] Please see again Figure 6A and Figure 6B As shown, the data signal 11 also includes pixel clearing header data 113 and pixel clearing waveform data 114. The driving circuit unit 20 determines the pixel clearing voltage value of the pixel clearing driving signal output to the panel unit 30 based on the pixel clearing header data 113, and the driving circuit unit 20 determines the pixel clearing driving duration of the pixel clearing driving signal with the pixel clearing voltage value based on the pixel clearing waveform data 114. In this embodiment, the pixel clearing driving signal is the pixel driving signal output by the driving circuit unit 20 to the pixel electrodes 31.

[0069] Please see Figure 7A and Figure 7BAs shown, the data signal 11 also includes pixel clear header data 113, pixel clear waveform data 114, pixel ULH header data 115, and pixel ULH waveform data 116. The driving circuit unit 20 determines the pixel clear voltage value of the pixel clear driving signal output to the panel unit 30 based on the pixel clear header data 113, and the driving circuit unit 20 determines the pixel clear driving duration of the pixel clear driving signal with the pixel clear voltage value based on the pixel clear waveform data 114. Furthermore, the driving circuit unit 20 also determines the pixel ULH voltage value of the pixel ULH driving signal output to the panel unit 30 based on the pixel ULH header data 115, and the driving circuit unit 20 determines the pixel ULH driving duration of the pixel ULH driving signal with the pixel ULH voltage value based on the pixel ULH waveform data 116. In this embodiment, both the pixel clear driving signal and the pixel ULH driving signal are pixel driving signals output by the driving circuit unit 20 to the plurality of pixel electrodes 31.

[0070] In addition, the data signal 11 also includes a blank data 110. For example... Figure 4B As shown, the blank data 110 is located between the pixel clear header data 113 and the pixel static display header data 111. Alternatively, as... Figure 5B As shown, the blank data 110 is located between the pixel clear header data 113 and the pixel ULH header data 115, and the blank data 110 is also located between the pixel ULH header data 115 and the pixel static display header data 111. Alternatively, as... Figure 6B As shown, the blank data 110 is located between the pixel clear waveform data 114 and the pixel static display header data 111. Alternatively, as... Figure 7B As shown, the blank data 110 is located between the pixel clear waveform data 114 and the pixel ULH header data 115, and the blank data 110 is also located between the pixel ULH waveform data 116 and the pixel static display header data 111.

[0071] The time occupied by the blank data 110 is used by the drive circuit unit 20 to output the pixel clear drive signal or the pixel ULH drive signal to the panel unit 30.

[0072] In detail, such as Figure 1As shown, in one embodiment, the timing control circuit unit 10 includes a clock output terminal (clock; clk), a display output enable control terminal (display output enable; doe), a display output ground control terminal (display output ground; dog), and a display start signal control terminal (display start pulse; dsp). The functions of the clock output terminal (clk), the display output enable control terminal (doe), the display output ground control terminal (dog), and the display start signal control terminal (dsp) of the timing control circuit unit 10 are the same as those of the timing control circuit unit 10 of existing multistable displays, and will not be described in detail here.

[0073] Furthermore, the timing control circuit unit 10 includes a header setting control terminal (dsh) and a data signal output terminal. In other embodiments, the data output terminal of the timing control circuit unit 10 includes multiple data output terminals, such as first to (n+1)th data output terminals (data 0 to data n). In this embodiment, the first to third data output terminals (data0 to data 2) are used as examples, but this is not a limitation.

[0074] The header setting control terminal (dsh) is connected to the drive circuit unit 20 and outputs a header setting signal 101 to the drive circuit unit 20. The data signal output terminal (data 0) is connected to the drive circuit unit 20 and outputs the data signal 11 to the drive circuit unit 20.

[0075] like Figure 3A and Figure 3B As shown, when the data signal 11 output by the data signal output terminal (data 0~data 2) is the static display header data 111 of the pixel, the header setting signal 101 output by the header setting control terminal (dsh) is a high voltage level. Figure 4A and Figure 4B As shown, when the data signal 11 output by the data signal output terminal (data 0~data 2) is the pixel clear header data 113, the header setting signal 101 output by the header setting control terminal (dsh) is the high voltage level. Figure 5A and Figure 5B As shown, when the data signal 11 output by the data signal output terminal (data 0~data 2) is the pixel ULH header data 115, the header setting signal 101 output by the header setting control terminal (dsh) is the high voltage level. Figure 7A and Figure 7BAs shown, when the data signal 11 output by the data signal output terminal (data 0~data 2) is not the pixel clear header data 113, the pixel ULH header data 115, or the pixel static display header data 111, the header setting signal 101 output by the header setting control terminal (dsh) is a low voltage level.

[0076] When the header setting signal 101 output by the header setting control terminal (dsh) is at the high voltage level, it means that the data signal 11 output by the data signal output terminal (data 0) is the pixel clear header data 113, the pixel ULH header data 115, or the pixel static display header data 111. In this way, the drive circuit unit 20 can determine whether the currently received data signal 11 is the pixel clear header data 113, the pixel ULH header data 115, or the pixel static display header data 111 by using the header setting signal 101.

[0077] Please see Figure 8A and Figure 8B As shown, the pixel clear header data 113 includes a pixel positive clear voltage data 1131 and a pixel negative clear voltage data 1132. Furthermore, the pixel clear header data 113 may also include clear clock data. This clear clock data is the number of clocks per unit time of clearing. The number of clocks per unit time of clearing refers to the number of clocks (clk) required for one duty period. For example, the clear clock data is a 3-bit binary number used to represent the decimal value 0 to 7; for example, binary 000 represents the decimal value 0, and binary 111 represents the decimal value 7. For instance, when the clear clock data is set to 100, it means that each duty period is 4 clocks (clk).

[0078] Furthermore, the pixel positive clear voltage data 1131 includes a first pixel positive clear voltage value 1131a and a second pixel positive clear voltage value 1131b, and the pixel negative clear voltage data 1132 includes a first pixel negative clear voltage value 1132a and a second pixel negative clear voltage value 1132b. In this embodiment, the first pixel positive clear voltage value 1131a is the first value of the first to third data output terminals (data 0 to data 2), and the first pixel positive clear voltage value 1131a is represented by a 3-bit binary data, namely V1(0) to V1(2), corresponding to a first voltage V1. For example, the binary value corresponding to the first voltage V1 is 001, that is, V1(2) = 0, V1(1) = 0, V1(0) = 1. The second pixel positive clear voltage value 1131b is the second value of the first to third data output terminals (data 0 to data 2), and this second pixel positive clear voltage value is also represented by a 3-bit binary data, corresponding to the first voltage V1. Similarly, the first pixel negative clear voltage value 1132a is the third value of the first to third data output terminals (data 0 to data 2), and this first pixel negative clear voltage value is represented by a 3-bit binary data, namely V4(0) to V4(2), corresponding to a fourth voltage V4. For example, the binary value corresponding to the fourth voltage V4 is 100, that is, V4(2) = 1, V4(1) = 0, V4(0) = 0. The second pixel negative clear voltage value 1132b is the fourth value of the first to third data output terminals (data 0 to data 2), and the second pixel negative clear voltage value 1132b is also represented by a 3-bit binary data, corresponding to the fourth voltage V4.

[0079] Please see Figure 9A and Figure 9BAs shown, the pixel clearing waveform data 114 includes several pixel electrode clearing data, such as first to nth pixel electrode clearing data 1141 to 114n. These pixel electrode clearing data include at least one first pixel electrode clearing data 1141, and the first pixel electrode clearing data 1141 includes a first clearing voltage unit number. In this embodiment, the first clearing voltage unit number is the value of the first to third data output terminals (data 0 to data 2), and the first clearing voltage unit number is represented by a 3-bit binary data format, i.e., pixel 1(0) to pixel 1(2), corresponding to a first pixel electrode. Furthermore, these pixel electrode clearing data may also include second to nth pixel electrode clearing data 1142 to 114n, and the second to nth pixel electrode clearing data 1142 to 114n each include a second to nth clearing voltage unit number. Similarly, the second clear voltage unit number is represented by a 3-bit binary data, namely pixel 2(0)~pixel2(2), corresponding to a second pixel electrode.

[0080] Furthermore, the drive circuit unit 20 has a duty count, and the drive circuit unit 20 determines a first remaining clear voltage unit by subtracting the first clear voltage unit from the duty count. For example, the duty count can be set to 7. When the first clear voltage unit is 100, representing the decimal value 4, the duty count minus the first clear voltage unit is 7 - 4 = 3, and the drive circuit unit 20 sets the first remaining clear voltage unit to 3. In other examples, when the first clear voltage unit is 111, representing the decimal value 7, the duty count minus the first clear voltage unit is 7 - 7 = 0, and the drive circuit unit 20 sets the first remaining clear voltage unit to 0.

[0081] In this embodiment, the pixel clearing header data 113 may also include a total number of jobs data. The driving circuit unit 20 can set the total number of jobs based on the total number of jobs data in the pixel clearing header data 113.

[0082] Furthermore, when the driving circuit unit 20 determines the pixel clearing drive duration for outputting the pixel clearing drive signal with the pixel clearing voltage value based on the pixel clearing waveform data 114, the driving circuit unit 20 determines a first clearing duration for outputting the pixel clearing drive signal with the first pixel positive clearing voltage value to the first pixel electrode based on the first clearing voltage units of the pixel clearing waveform data 114, and the driving circuit unit 20 determines a second clearing duration for outputting the pixel clearing drive signal with the second pixel positive clearing voltage value to the first pixel electrode based on the first remaining clearing voltage units, and the driving circuit unit 20 determines a third clearing duration for outputting the pixel clearing drive signal with the first pixel negative clearing voltage value to the first pixel electrode based on the first clearing voltage units of the pixel clearing waveform data, and the driving circuit unit determines a fourth clearing duration for outputting the pixel clearing drive signal with the second negative clearing voltage value to the first pixel electrode based on the first remaining clearing voltage units.

[0083] Please see Figure 10A and Figure 10B As shown, the pixel static display header data 111 includes positive display voltage data 1111 and negative display voltage data 1112. Furthermore, the pixel static display header data 111 may also include display clock data, which contains the number of clocks per unit time. The number of clocks per unit time refers to the number of clocks (clk) required for one duty period. For example, the display clock data is a 3-bit binary number used to represent the decimal value 0-7; for example, binary 000 represents the decimal value 0, and binary 111 represents the decimal value 7. For instance, when the display clock data is set to 100, it represents a duty period of 4 clocks (clk).

[0084] Furthermore, the positive display voltage data 1111 includes a first positive display voltage value 1111a and a second positive display voltage value 1111b, and the negative display voltage data 1112 includes a first negative display voltage value 1112a and a second negative display voltage value 1112b. In this embodiment, the first positive display voltage value 1111a is the first value of the first to third data output terminals (data 0 to data 2), and the first positive display voltage value is represented by a 3-bit binary data, namely V2(0) to V2(2), corresponding to a second voltage V2. For example, the binary value corresponding to the second voltage V2 is 010, that is, V2(2) = 0, V2(1) = 1, V2(0) = 0. The positive display voltage value 1111b of the second pixel is the second value of the first to third data output terminals (data 0 to data 2), and the positive display voltage value of the second pixel is also represented by a 3-bit binary data form, namely V3(0) to V3(2), corresponding to a third voltage V3. For example, the binary value corresponding to the third voltage V3 is 011, that is, V3(2) = 0, V3(1) = 1, V3(0) = 1. Similarly, the negative display voltage value 1112a of the first pixel is the third value of the first to third data output terminals (data 0 to data 2), and the negative display voltage value 1112a of the first pixel is represented by a 3-bit binary data form, namely V5(0) to V5(2), corresponding to a fifth voltage V5. For example, the binary value corresponding to the fifth voltage V5 is 101, that is, V5(2) = 1, V5(1) = 0, V5(0) = 1. The second pixel negative display voltage value 1112b is the fourth value of the first to third data output terminals (data 0 to data 2), and the second pixel negative display voltage value is also represented by a 3-bit binary data, namely V6(0) to V6(2), corresponding to a sixth voltage V6. For example, the binary value corresponding to the sixth voltage V6 is 110, that is, V6(2) = 1, V6(1) = 1, V6(0) = 0.

[0085] Please see Figure 11A and Figure 11BAs shown, the pixel static display waveform data 112 includes several pixel electrode display data, such as first to nth pixel electrode display data 1121 to 112n. These several pixel electrode display data include at least one first pixel electrode display data 1121, and the first pixel electrode display data 1121 includes a first display voltage unit number. In this embodiment, the first display voltage unit number is the value of the first to third data output terminals (data 0 to data2), and the first display voltage unit number is represented by a 3-bit binary data format, i.e., pixel 1(0) to pixel 1(2), corresponding to the first pixel electrode. Furthermore, these several pixel electrode display data may also include second to nth pixel electrode display data 1122 to 112n, and the second to nth pixel electrode display data 1122 to 112n each include a second to nth display voltage unit number. Similarly, the second display voltage unit number is the value of the first to third data output terminals (data 0 to data 2), and the second display voltage unit number is represented by a 3-bit binary data, namely pixel 2(0) to pixel 2(2), corresponding to the second pixel electrode.

[0086] Furthermore, the drive circuit unit 20 has a duty count, and the drive circuit unit 20 determines a first remaining display voltage unit by subtracting the first display voltage unit from the duty count. For example, the duty count is set to 7. When the first display voltage unit is 100, representing the decimal value 4, the duty count minus the first display voltage unit is 7 - 4 = 3, and the drive circuit unit 20 sets the first remaining display voltage unit to 3. In other examples, when the first display voltage unit is 111, representing the decimal value 7, the duty count minus the first display voltage unit is 7 - 7 = 0, and the drive circuit unit 20 sets the first remaining display voltage unit to 0.

[0087] In this embodiment, the pixel static display header data 111 may also include the total number of jobs data. Furthermore, the driving circuit unit 20 can set the total number of jobs based on the total number of jobs data in the pixel static display header data 111.

[0088] Furthermore, when the driving circuit unit 20 determines the pixel display driving duration for outputting the pixel display driving signal having the pixel display voltage value based on the pixel static display waveform data 112, the driving circuit unit 20 determines a first display duration for the pixel display driving signal output to the first pixel electrode having the positive display voltage value of the first pixel based on the first number of display voltage units in the pixel static display waveform data 112, and the driving circuit unit 20 determines a second display duration for the pixel display driving signal output to the first pixel electrode having the positive display voltage value of the second pixel based on the first remaining number of display voltage units, and the driving circuit unit 20 determines a third display duration for the pixel display driving signal output to the first pixel electrode having the negative display voltage value of the first pixel based on the first number of display voltage units in the pixel static display waveform data, and the driving circuit unit 20 determines a fourth display duration for the pixel display driving signal output to the first pixel electrode having the negative display voltage value of the second pixel based on the first remaining number of display voltage units.

[0089] For example, please refer to Figure 12 As shown, the preset total number of operations is 7. As shown in the first pixel electrode clearing data 1141, the number of first clearing voltage units is 111. As shown in the second pixel electrode clearing data 1142, the number of second clearing voltage units is 111. As shown in the first pixel positive clearing voltage value 1131a, the first pixel positive clearing voltage value is the first voltage V1, i.e., 001. As shown in the second pixel positive clearing voltage value 1131b, the second pixel positive clearing voltage value is the first voltage V1, i.e., 001. As shown in the first pixel negative clearing voltage value 1132a, the first pixel negative clearing voltage value is the fourth voltage V4, i.e., 100. As shown in the second pixel negative clearing voltage value 1132b, the second pixel negative clearing voltage value is the fourth voltage V4, i.e., 100. As shown in the first pixel electrode display data 1121, the number of first display voltage units is 100. As shown in the second pixel electrode display data 1122, the number of second display voltage units is 111. As shown by the positive display voltage value 1111a of the first pixel, the positive display voltage value of the first pixel is the second voltage V2, i.e., 010. As shown by the positive display voltage value 1111b of the second pixel, the positive display voltage value of the second pixel is the third voltage V3, i.e., 011. As shown by the negative display voltage value 1112a of the first pixel, the negative display voltage value of the first pixel is the fifth voltage V5, i.e., 101. As shown by the negative display voltage value 1112b of the second pixel, the negative display voltage value of the second pixel is the sixth voltage V6, i.e., 110.

[0090] Since the first clear voltage unit number is 111, the first clear duration of the pixel clear driving signal with the first pixel positive clear voltage value (i.e., the first voltage V1) output by the driving circuit unit 20 to the first pixel electrode is 7 working hours. And since the total number of working hours is 7, the first remaining clear voltage unit number is 0, and the second clear duration of the pixel clear driving signal with the second pixel positive clear voltage value (i.e., the first voltage V1) output by the driving circuit unit 20 to the first pixel electrode is 0 working hours. Furthermore, after the driving circuit unit 20 outputs the pixel clear driving signal with the first voltage V1 to the first pixel electrode, the driving circuit unit 20 enters a negative half-cycle, and then outputs the pixel clear driving signal with the first pixel negative clear voltage value (i.e., the fourth voltage V4) to the first pixel electrode for the first clear duration, and the first clear duration is 7 working hours. Furthermore, since the total number of working units is 7, the number of the first remaining clear voltage units is 0, and the second clear duration of the pixel clear drive signal with the second pixel negative clear voltage value (i.e., the fourth voltage V4) output by the drive circuit unit 20 to the first pixel electrode is 0 working hours (duty).

[0091] Similarly, since the second clear voltage unit number is 111, the first clear duration of the pixel clear drive signal with the first pixel positive clear voltage value (the first voltage V1) output by the driving circuit unit 20 to the second pixel electrode is 7 working hours. And since the total number of working hours is 7, the first remaining clear voltage unit number is 0, and the second clear duration of the pixel clear drive signal with the second pixel positive clear voltage value (i.e., the first voltage V1) output by the driving circuit unit 20 to the second pixel electrode is 0 working hours. Furthermore, after the driving circuit unit 20 outputs the pixel clear drive signal with the first voltage V1 to the second pixel electrode, the driving circuit unit 20 enters a negative half-cycle, and then the driving circuit unit 20 outputs the pixel clear drive signal with the first pixel negative clear voltage value, i.e., the fourth voltage V4), to the second pixel electrode for the first clear duration, and the first clear duration is 7 working hours. Furthermore, since the total number of working units is 7, the number of the first remaining clear voltage units is 0, and the second clear duration of the pixel clear drive signal with the second pixel negative clear voltage value (i.e., the fourth voltage V4) output by the drive circuit unit 20 to the second pixel electrode is 0 working hours (duty).

[0092] Since the first display voltage unit number is 100, the first display duration of the pixel display driving signal with the positive display voltage value of the first pixel (i.e., the second voltage V2) output by the driving circuit unit 20 to the first pixel electrode is 4 working hours (duty). And since the total number of working hours is 7, the first remaining display voltage unit number is 3, the second display duration of the pixel display driving signal with the positive display voltage value of the second pixel (i.e., the third voltage V3) output by the driving circuit unit 20 to the first pixel electrode is 3 working hours (duty). Furthermore, after the driving circuit unit 20 outputs the pixel display driving signal with the third voltage V3 to the first pixel electrode, the driving circuit unit 20 enters a negative half-cycle, and then outputs the pixel display driving signal with the negative display voltage value of the first pixel (the fifth voltage V5) to the first pixel electrode for the first display duration, and the first display duration is 4 working hours (duty). Furthermore, since the total number of working units is 7, the number of the first remaining display voltage units is 3, and the second display duration of the pixel display driving signal with the second pixel negative display voltage value (i.e., the sixth voltage V6) output by the driving circuit unit 20 to the first pixel electrode is 3 working hours (duty).

[0093] Similarly, since the second display voltage unit number is 111, the first display duration of the pixel display driving signal output by the driving circuit unit 20 to the second pixel, which has the positive display voltage value of the first pixel (i.e., the second voltage V2), is 7 working hours (duty). And since the total number of working hours is 7, the first remaining display voltage unit number is 0, so the second display duration of the pixel display driving signal output by the driving circuit unit 20 to the second pixel, which has the positive display voltage value of the second pixel (i.e., the third voltage V3), is 0 working hours (duty). Furthermore, after the driving circuit unit 20 outputs the pixel display driving signal with the second voltage V2 to the second pixel, the driving circuit unit 20 enters a negative half-cycle, and then outputs the pixel display driving signal with the negative display voltage value of the first pixel (i.e., the fifth voltage V5) to the second pixel for the first display duration, and the first display duration is 7 working hours (duty). Furthermore, since the total number of working units is 7, the number of the first remaining display voltage units is 0, and the second display duration of the pixel display drive signal output by the drive circuit unit 20 to the second pixel having the negative display voltage value of the second pixel (i.e., the sixth voltage V6) is 0 working hours (duty).

[0094] like Figure 13A and Figure 13B As shown, Figure 13AThis is a waveform diagram of the first pixel display drive signal 201 output by the drive circuit unit 20 to the first pixel electrode. Figure 13B This is a waveform diagram of the second pixel display drive signal 202 output by the drive circuit unit 20 to the second pixel electrode.

[0095] For example, consider a multistable display driven by a Full HD static display with a resolution of 1920×1080. When transmitting at a single data rate (SDR), one pixel electrode's data is transmitted per clock cycle, meaning the number of pixels transmitted per clock cycle is 1. Furthermore, the transmission time (T) for each frame's data is set. line The time is 5 milliseconds (ms).

[0096] The clock rate for driving the multistable display in static display mode is calculated using the following formula:

[0097]

[0098] The resolution is 1920. The number of pixels transmitted per clock clock is 1 at Single Data Rate (SDR). Transmission time (T) Iine The value is 5 milliseconds (ms). Substituting the above figures into the formula yields the following Table 2.

[0099]

[0100] Table 2

[0101] As can be seen from the comparison of Tables 1 and 2, the clock rate of the static display driving multistable display of the present invention can be significantly reduced. In this way, the static display driving multistable display can adopt a low-frequency driving scheme, thereby effectively reducing power consumption.

[0102] Furthermore, such as Figure 14As shown, in a fourth embodiment, the timing control circuit unit 10 includes a clock output terminal (clock; clk), a display output enable control terminal (display output enable; doe), a display output ground control terminal (display output ground; dog), a display start pulse control terminal (display start pulse; dsp), and a digital-to-analog conversion control terminal (d2a). The functions of the clock output terminal (clk), the display output enable control terminal (doe), the display output ground control terminal (dog), and the display start pulse control terminal (dsp) of the timing control circuit unit 10 are the same as those of the timing control circuit unit 10 of existing multi-stable displays, and will not be described in detail here.

[0103] The digital-to-analog conversion control terminal (d2a) is connected to the drive circuit unit 20.

[0104] Furthermore, the timing control circuit unit 10 also includes the header setting control terminal (dsh) and the data signal output terminal. In other embodiments, the data signal output terminal of the timing control circuit unit 10 may include several data output terminals, such as the first to the (n+1)th data output terminals (data 0 to data n). In this embodiment, the first to the third data output terminals (data 0 to data 2) are used as examples, but this is not a limitation.

[0105] like Figure 15A and Figure 15B As shown, the data signal 11 contains several blank data 110, one of which is located between the pixel clear waveform data 114 and the pixel ULH header data 115, another blank data 110 is located between the pixel ULH waveform data and the pixel static display header data 111, and yet another blank data 110 follows the pixel static display waveform data 112.

[0106] In this embodiment, the drive circuit unit 20 has the total number of working data. When the data signal 11 is blank data 110, the digital-to-analog conversion control terminal (d2a) outputs a count signal 102 that is an even multiple of the total number of working data. For example, when the data signal 11 is blank data 110, the digital-to-analog conversion control terminal (d2a) outputs a count signal 102 that is twice the total number of working data, but this is not a limitation.

[0107] Furthermore, when the data signal 11 is the waveform data 112 to be displayed for that pixel, the digital-to-analog conversion control terminal (d2a) can also output a count signal 102 that is an even multiple of the total number of operations. For example, when the data signal 11 is the waveform data 112 to be displayed for that pixel, the digital-to-analog conversion control terminal (d2a) outputs a count signal 102 that is twice the total number of operations, but this is not a limitation.

[0108] Furthermore, such as Figure 16 As shown, in this embodiment, the pixel clearing header data 113 includes a pixel positive clearing voltage data 1131 and a pixel negative clearing voltage data 1132. The pixel positive clearing voltage data 1131 includes a first pixel positive clearing voltage value 1131a and a second pixel positive clearing voltage value 1131b, and the pixel negative clearing voltage data 1132 includes a first pixel negative clearing voltage value 1132a and a second pixel negative clearing voltage value 1132b. In this embodiment, the timing control circuit unit 10 includes the first to third data output terminals (data 0 to data 2), and the first pixel positive clearing voltage value 1131a is the first value of the first to third data output terminals (data 0 to data 2), and the first pixel positive clearing voltage value 1131a is represented by a 3-bit binary data, namely V1(0) to V1(2), corresponding to a first voltage V1, for example 001. The second pixel positive clear voltage value 1131b is the second value of the first to third data output terminals (data 0 to data 2), and it is also represented by a 3-bit binary number, corresponding to the first voltage V1, for example, 001. Similarly, the first pixel negative clear voltage value 1132a is the third value of the first to third data output terminals (data 0 to data 2), and it is represented by a 3-bit binary number, namely V4(0) to V4(2), corresponding to a fourth voltage V4, for example, 100. The second pixel negative clear voltage value 1132b is the fourth value of the first to third data output terminals (data 0 to data 2), and it is also represented by a 3-bit binary number, corresponding to the fourth voltage V4, for example, 100.

[0109] The pixel clearing waveform data 114 includes several pixel electrode clearing data. These several pixel electrode clearing data include at least one first pixel electrode clearing data 1141, and the first pixel electrode clearing data 1141 includes a first clearing voltage unit number. In this embodiment, the first clearing voltage unit number is two values ​​from the first to third data output terminals (data0 to data 2), and the first clearing voltage unit number is represented by a 3-bit binary data, i.e., pixel 1(0) to pixel 1(2), corresponding to the first pixel electrode, for example, 111 as shown in the first pixel electrode clearing data 1141. Furthermore, the several pixel electrode clearing data may also include second to nth pixel electrode clearing data 1142 to 114n, and the second to nth pixel electrode clearing data 1142 to 114n each include a second to nth clearing voltage unit number. Similarly, the second clear voltage unit number is the value of the first to third data output terminals (data 0 to data 2), and the second clear voltage unit number is represented by a 3-bit binary data, namely pixel 2(0) to pixel2(2), corresponding to a second pixel electrode, such as 111 shown in the second pixel electrode clear data 1142.

[0110] Furthermore, when the driving circuit unit 20 determines the pixel clearing drive duration for outputting the pixel clearing drive signal with the pixel clearing voltage value based on the pixel clearing waveform data 114, the driving circuit unit 20 outputs the pixel clearing drive signal with the first pixel positive clearing voltage value to the first pixel electrode between the first to the Ath count signals 102 output from the digital-to-analog conversion control terminal (d2a), and the driving circuit unit 20 outputs the second... The pixel clearing drive signal with the positive clearing voltage value is sent to the first pixel electrode. The driving circuit unit 20 outputs a pixel clearing drive signal with the negative clearing voltage value of the first pixel to the first pixel electrode between the (B+1)th and (A+B)th count signals 102 output from the digital-to-analog conversion control terminal (d2a). The driving circuit unit 20 also outputs a pixel clearing drive signal with the negative clearing voltage value of the second pixel to the first pixel electrode between the (A+B+1)th and (2B)th count signals 102 output from the digital-to-analog conversion control terminal (d2a). In this embodiment, A is the number of units of the first clearing voltage, and B is the total number of working units.

[0111] The pixel static display header data 111 includes a pixel positive display voltage data 1111 and a pixel negative display voltage data 1112. The pixel positive display voltage data 1111 includes a first pixel positive display voltage value 1111a and a second pixel positive display voltage value 1111b, and the pixel negative display voltage data 1112 includes a first pixel negative display voltage value 1112a and a second pixel negative display voltage value 1112b. In this embodiment, the timing control circuit unit 10 includes the first to third data output terminals (data 0 to data 2), and the first pixel positive display voltage value 1111a is the value of the first to third data output terminals (data 0 to data 2), and the first pixel positive display voltage value 1111a is represented by a 3-bit binary data, namely V2(0) to V2(2), corresponding to a second voltage V2, namely 010. The positive display voltage value 1111b of the second pixel is the value of the first to third data output terminals (data 0 to data 2), and the positive display voltage value 1111b of the second pixel is also represented by a 3-bit binary data form, namely V3(0) to V3(2), corresponding to a third voltage V3, i.e., 011. Similarly, the negative display voltage value 1112a of the first pixel is the value of the first to third data output terminals (data 0 to data 2), and the negative display voltage value 1112a of the first pixel is represented by a 3-bit binary data form, namely V5(0) to V5(2), corresponding to a fifth voltage V5, i.e., 101. The negative display voltage value of the second pixel is the value of the first to third data output terminals (data 0 to data 2), and the negative display voltage value 1112b of the second pixel is also represented by a 3-bit binary data form, namely V6(0) to V6(2), corresponding to a sixth voltage V6, i.e., 110.

[0112] The pixel static display waveform data 112 includes several pixel electrode display data. These several pixel electrode display data include at least one first pixel electrode display data 1121, and the first pixel electrode display data 1121 includes a first display voltage unit number. In this embodiment, the first display voltage unit number is two values ​​from the first to third data output terminals (data 0 to data 2), and the first display voltage unit number is represented by a 3-bit binary data format, i.e., pixel 1(0) to pixel 1(2), corresponding to the first pixel electrode, for example, 100 as shown by the first pixel electrode display data 1121. Furthermore, the several pixel electrode display data may also include second to nth pixel electrode display data 1122 to 112n, and the second to nth pixel electrode display data 1122 to 112n each include a second to nth display voltage unit number. Similarly, the second display voltage unit number is two values ​​of the first to third data output terminals (data 0 to data2), and the second display voltage unit number is represented by a 3-bit binary data, namely pixel2(0) to pixel2(2), corresponding to the second pixel electrode, for example, 111 shown by the data 1122 displayed by the second pixel electrode.

[0113] Furthermore, when the driving circuit unit 20 determines the pixel display driving duration for outputting the pixel display driving signal with the pixel display voltage value based on the pixel static display waveform data 112, the driving circuit unit 20 outputs the pixel display driving signal with the first pixel positive display voltage value to a first pixel electrode between the first to C count signals 102 output from the digital-to-analog conversion control terminal (d2a), and the driving circuit unit 20 outputs the pixel display driving signal with the first pixel positive display voltage value to a first pixel electrode between the (C+1)th to Bth count signals 102 output from the digital-to-analog conversion control terminal (d2a). The second pixel positive display voltage value is sent to the first pixel electrode, and the driving circuit unit 20 outputs a pixel display driving signal with the first pixel negative display voltage value to the first pixel electrode between the (B+1)th and (B+C)th count signals 102 output from the digital-to-analog conversion control terminal (d2a). The driving circuit unit 20 also outputs a pixel display driving signal with the second pixel negative display voltage value to the first pixel electrode between the (B+C+1)th and (2B)th count signals 102 output from the digital-to-analog conversion control terminal (d2a). In this embodiment, C is the number of first display voltage units, and B is the total number of working units.

[0114] For example, the preset total number of operations is 7. As shown in the first pixel electrode clearing data 1141, the number of first clearing voltage units is 111. As shown in the second pixel electrode clearing data 1142, the number of second clearing voltage units is 111. As shown in the first pixel positive clearing voltage value 1131a, the first pixel positive clearing voltage value is the first voltage V1, i.e., 001. As shown in the second pixel positive clearing voltage value 1131b, the second pixel positive clearing voltage value is the first voltage V1, i.e., 001. As shown in the first pixel negative clearing voltage value 1132a, the first pixel negative clearing voltage value is the fourth voltage V4, i.e., 100. As shown in the second pixel negative clearing voltage value 1132b, the second pixel negative clearing voltage value is the fourth voltage V4, i.e., 100. As shown in the first pixel electrode display data 1121, the number of first display voltage units is 100. As shown in the second pixel electrode display data 1122, the number of second display voltage units is 111. As shown by the positive display voltage value 1111a of the first pixel, the positive display voltage value of the first pixel is the second voltage V2, i.e., 010. As shown by the positive display voltage value 1111b of the second pixel, the positive display voltage value of the second pixel is the third voltage V3, i.e., 011. As shown by the negative display voltage value 1112a of the first pixel, the negative display voltage value of the first pixel is the fifth voltage V5, i.e., 101. As shown by the negative display voltage value 1112b of the second pixel, the negative display voltage value of the second pixel is the sixth voltage V6, i.e., 110.

[0115] Please refer to the following: Figures 17A to 17C As shown, since the number of units of the first clear voltage is 111, the first clear duration of the pixel clear drive signal with the first pixel positive clear voltage value, i.e., the first voltage V1, output by the drive circuit unit 20 to the first pixel electrode is 7 working hours. Therefore, the drive circuit unit 20 outputs the pixel clear drive signal with the first pixel positive clear voltage value (i.e., the first voltage V1) to the first pixel electrode between the first and seventh count signals 102 output from the digital-to-analog conversion control terminal (d2a). Although the driving circuit unit 20 outputs a pixel clearing drive signal with the second pixel positive clearing voltage value to the first pixel electrode between the (A+1)th and Bth count signals 102 output from the digital-to-analog conversion control terminal (d2a), since the number of first clearing voltage units is 7 (A=7, A+1=7+1=8), and the total number of working units is 7, the number of first clearing voltage units (A)+1 is greater than the total number of working units (B), i.e., A+1=7+1=8>7. Therefore, the driving circuit unit 20 will not output a pixel clearing drive signal with the second pixel positive clearing voltage value, i.e., the first voltage V1, to the first pixel electrode.

[0116] Furthermore, after the driving circuit unit 20 outputs the pixel clearing driving signal with the first voltage V1 to the first pixel electrode, the driving circuit unit 20 enters the negative half-cycle. The driving circuit unit 20 outputs the pixel clearing driving signal with the first pixel negative clearing voltage value, i.e., the fourth voltage V4, to the first pixel electrode between the 8th to 14th count signals 102 output from the digital-to-analog conversion control terminal (d2a). Although the driving circuit unit 20 outputs the pixel clearing driving signal with the second pixel negative clearing voltage value to the first pixel electrode between the A+B+1th to 2Bth count signals output from the digital-to-analog conversion control terminal (d2a), since A+B+1=7+7+1=15, and 2B=2×7=14, that is, the total number of operations (B) + the number of first clearing voltage units (A)+1 is greater than twice the total number of operations (B), i.e., 7+7+1=15>2×7=14. Therefore, the driving circuit unit 20 will not output the pixel clearing driving signal with the second pixel negative clearing voltage value (i.e. the first voltage V4) to the first pixel electrode.

[0117] The generation method of the pixel clearing drive signal output by the drive circuit unit 20 to the second pixel electrode is the same as that output by the drive circuit unit 20 to the first pixel electrode, and will not be described again here.

[0118] Since the first display voltage unit number is 100, the first display duration of the pixel display driving signal output by the driving circuit unit 20 to the first pixel electrode, which has the first pixel positive display voltage value (i.e., the second voltage V2), is 4 working hours. Therefore, the driving circuit unit 20 outputs the pixel display driving signal with the first pixel positive display voltage value (i.e., the second voltage V2) to the first pixel electrode between the first to fourth count signals 102 output from the digital-to-analog conversion control terminal (d2a). Furthermore, the driving circuit unit 20 outputs the pixel display driving signal with the second pixel positive display voltage value (i.e., the third voltage V3) to the first pixel electrode between the fifth to seventh count signals output from the digital-to-analog conversion control terminal (d2a).

[0119] Furthermore, after the driving circuit unit 20 outputs the pixel display driving signal with the third voltage V3 to the first pixel electrode, the driving circuit unit 20 enters the negative half-cycle. The driving circuit unit 20 outputs the pixel display driving signal with the negative display voltage value of the first pixel (i.e., the fifth voltage V5) to the first pixel electrode between the 8th and 11th count signals 102 output from the digital-to-analog conversion control terminal (d2a). The driving circuit unit 20 also outputs the pixel display driving signal with the negative display voltage value of the second pixel (i.e., the sixth voltage V6) to the first pixel electrode between the 12th and 14th count signals 102 output from the digital-to-analog conversion control terminal (d2a).

[0120] Similarly, since the second display voltage unit number is 111, the driving circuit unit 20 outputs a pixel display driving signal with the positive display voltage value of the first pixel (i.e., the second voltage V2) to the second pixel electrode between the first to the seventh count signals 102 output from the digital-to-analog conversion control terminal (d2a). Since the total number of operations is 7, the period after the seventh count signal 102 is a negative half-cycle, and the driving circuit unit 20 does not output a pixel display driving signal with the positive display voltage value of the second pixel (i.e., the third voltage V3) to the second pixel electrode.

[0121] Furthermore, when the driving circuit unit 20 enters the negative half-cycle, it outputs a pixel display driving signal with the negative display voltage value of the first pixel (i.e., the fifth voltage V5) to the second pixel electrode between the 8th and 14th count signals 102 output from the digital-to-analog conversion control terminal (d2a). However, since twice the total number of operations is 14, the cycle ends after the 14th count signal 102, and the driving circuit unit 20 does not output a pixel display driving signal with the negative display voltage value of the second pixel (i.e., the sixth voltage V6) to the second pixel electrode.

[0122] like Figure 17A and Figure 17B As shown, Figure 17A This is a waveform diagram of the first pixel display drive signal 201 output by the drive circuit unit 20 to the first pixel electrode. Figure 17B This is a waveform diagram of the second pixel display drive signal 202 output by the drive circuit unit 20 to the second pixel.

[0123] For example, consider a multistable display driven by a Full HD static display with a resolution of 1920×1080. When transmitting at a single data rate (SDR), one pixel of data is transmitted per clock cycle, meaning the number of pixels transmitted per clock cycle is 1. Furthermore, the transmission time (T) for each frame of data is set. line The time is 5 milliseconds (ms).

[0124] The clock rate for driving the multistable display in static display mode is calculated using the following formula:

[0125]

[0126] The resolution is 1920. The number of pixels transmitted per clock clock is 1 at Single Data Rate (SDR). Transmission time (T) line The value is 5 milliseconds (ms). Substituting the above figures into the formula yields the following Table 2.

[0127]

[0128] Table 3

[0129] As can be seen from the comparison of Tables 1 and 3, the clock rate of the static display driving multistable display of the present invention can be significantly reduced. In this way, the static display driving multistable display can adopt a low-frequency driving scheme, thereby effectively reducing power consumption.

[0130] In summary, since the clock rate is independent of the duty count, the static display driver multistable display of this invention can achieve the same transmission time (T) within the same transmission time. line Under the conditions of, for example, T line =5ms, the clock rate can be significantly reduced to the kilohertz (kHz) level. In other words, this static display driver for multistable displays can use a low-frequency driving scheme, thereby effectively reducing power consumption.

[0131] Furthermore, the static display driver multistable display of the present invention only needs to transmit data once to complete the transmission of the voltage waveform of a frame. The voltage configuration of multiple working intervals (duties) within a frame can be directly determined based on the pixel static display header data 111 and the pixel static display waveform data 112, without the need to transmit different voltage configurations for each working interval (duty) within a frame for switching. Therefore, for the display start signal control terminal (DSP), the display start signal control terminal (DSP) only needs to output one cycle for each frame, without needing to output one cycle for each working interval (duty), thereby significantly reducing the number of switching times of the output signal of the display start signal control terminal (DSP), and thus reducing dynamic power consumption.

[0132] Furthermore, since the counting signal 102 output by the digital-to-analog conversion control terminal (d2a) is used for counting, the data signal output terminal can continuously transmit data during the holding time of the counting signal 102 output by the digital-to-analog conversion control terminal (d2a), without affecting the digital-to-analog conversion, and thus preventing the generation of data bubbles. In other words, during the holding time of the counting signal 102 output by the digital-to-analog conversion control terminal (d2a), the data signal output terminal (data 0) can continuously transmit data without interrupting the transmission to avoid the generation of data bubbles, thereby further improving transmission efficiency.

[0133] Furthermore, since the counting signal 102 output by the digital-to-analog conversion control terminal (d2a) of the static display driving multistable display of the present invention is used for counting, the waveform data of the first frame needs to be transmitted before the rising edge of the first counting signal 102. During the counting periods of the second to nth counting signals 102, the waveform data of the next frame can be transmitted, and the transmission can be completed before the rising edge of the (n+1)th counting signal 102. For example, assuming that the voltage waveform of a frame has 4 working intervals, the data signal output terminal needs to transmit the waveform data of the first frame before the rising edge of the first counting signal 102. During the counting periods of the second to fourth counting signals 102, the waveform data of the second frame can be transmitted, and the transmission can be completed before the rising edge of the fifth counting signal 102. This allows for a buffer time between two consecutive frames of waveform data, eliminating the need for tightly continuous transmission and providing greater design flexibility.

[0134] Furthermore, in existing multistable displays, the signal output from the digital-to-analog conversion control terminal (d2a) is used for digital-to-analog conversion. Therefore, in each working interval (duty) of a frame, the digital-to-analog conversion control terminal (d2a) needs to output one cycle of signal. Only after the digital-to-analog conversion control terminal (d2a) outputs one cycle of signal will the data signal output terminal output the waveform data for the next working interval (duty), until the waveform data for the last working interval (duty) is output. More specifically, after the waveform data for the last working interval (duty) of the last frame (frame) is output, the digital-to-analog conversion control terminal (d2a) needs to output another cycle of signal. After the digital-to-analog conversion control terminal (d2a) outputs the last cycle of signal, the data signal output terminal no longer needs to output waveform data. In other words, the data signal output terminal of existing multistable displays only stops outputting waveform data after the signal output of the last digital-to-analog conversion control terminal (d2a).

[0135] However, the counting signal 102 output by the digital-to-analog conversion control terminal (d2a) of the static display driving multistable display of the present invention is used for counting. The data signal output terminal only needs to complete the transmission of waveform data before the rising edge of the first counting signal 102. Therefore, after the waveform data of the last frame is output, the data signal output terminal does not need to output the waveform data. That is to say, after the waveform data of the last frame is output, the data signal output terminal does not need to output the waveform data during the period of the counting signal 102 output by the digital-to-analog conversion control terminal (d2a). For example, assuming that the voltage waveform of the last frame has 4 working intervals, the data signal output terminal only needs to complete the transmission of the waveform data of the last frame before the rising edge of the first counting signal 102, and during the counting period of the first to fourth counting signals 102 of the last frame, the data signal output terminal does not need to transmit waveform data again.

[0136] Furthermore, as described in the above embodiments, the driving circuit unit 20 determines the pixel display driving voltage value of the pixel display driving signal output to the panel unit 30 based on the pixel static display header data 111, and determines the pixel display driving duration of the pixel display driving signal with the pixel display voltage value based on the pixel static display waveform data 112. Moreover, when the driving circuit unit 20 determines the pixel display driving duration of the pixel display driving signal with the pixel display voltage value based on the pixel static display waveform data 112, the driving circuit unit 20 determines the number of display voltage units based on the waveform data 11b, and then determines the display duration of the first pixel positive display voltage value and the first pixel negative display voltage value based on the number of display voltage units. Next, the driving circuit unit 20 also determines the display duration of the second pixel positive display voltage value and the second pixel negative display voltage value after subtracting the number of display voltage units from the total number of operations. In other words, the pixel static display waveform data 112 corresponds to the holding time of each voltage value. When the driving circuit unit 20 receives the pixel static display waveform data 112, it calculates the number of the counting signals 102 output by the digital-to-analog conversion control terminal (d2a) based on the pixel static display waveform data 112, in order to calculate the pixel display driving duration of the pixel display driving signal with the pixel display voltage value. Therefore, the driving circuit unit 20 only needs the pixel static display waveform data 112 to determine the entire waveform of the pixel display driving signal for each pixel, thereby significantly reducing the amount of data that needs to be transmitted.

[0137] Furthermore, since the timing control circuit unit 10 only outputs a signal to drive the drive circuit unit 20 to output the line drive signal after the pixel clear header data and the pixel clear waveform data have been output, the timing control circuit unit 10 does not need to provide data during the period when the drive circuit unit 20 outputs the pixel positive clear voltage and the pixel negative clear voltage, and in the Uniform Lying Helix (ULH) steady-state mode.

[0138] Please see Figure 18 As shown, the timing control circuit unit 10 also includes a scan output terminal. In other embodiments, the scan output terminal of the timing control circuit unit 10 may include multiple scan output terminals, such as the first to the (n+1)th scan output terminals (scan 0 to scan n). In this embodiment, the first to the third data output terminals (scan 0 to scan 2) are used as examples, but this is not a limitation.

[0139] Please see Figures 19A to 19CAs shown, the timing control signal includes a scan signal 21, and the scan signal 21 includes line static display header data 211 and line static display waveform data 212. The drive circuit unit 20 determines a line drive voltage value of a line drive signal output to the panel unit 30 based on the line static display header data 211, and the drive circuit unit 20 determines a signal waveform of the line drive signal output to the panel unit 30 based on the line drive voltage value and the line static display waveform data 212.

[0140] For example, please refer to Figure 20A and Figure 20B As shown, the static display header data 211 of the line includes at least one line positive display voltage data 2111 and one line negative display voltage data 2112, but is not limited thereto. In this embodiment, the timing control circuit unit 10 includes the first to third scan output terminals (scan 0 to scan 2), and the first line positive display voltage data 2111 includes a first line positive display voltage value 2111a and a second line positive display voltage value 2111b, and the first line positive display voltage value 2111a is the value of the first to third scan output terminals (scan 0 to scan 2), that is, V6(0) to V6(2), which corresponds to the sixth voltage V6, for example. Figure 22 As shown, the first line is displaying a voltage value 2111a of 110. Similarly, the second line is displaying a voltage value 2111b of V2(0) to V2(2), corresponding to the second voltage V2, for example... Figure 22 As shown, the positive voltage value 2111b of the second line is 010. The negative voltage data 2112 of the first line includes a negative voltage value 2112a and a negative voltage value 2112b. The negative voltage value 2112a of the first line is V3(0) to V3(2), corresponding to the third voltage V3, for example... Figure 22 As shown, the first line negative display voltage value 2112a is 011. And the second line negative display voltage value 2112b is V5(0)~V5(2), corresponding to the fifth voltage V5, for example... Figure 22 As shown, the negative display voltage value 2112b of the second line is 101.

[0141] Please see Figure 21A and Figure 21BAs shown, the scan display waveform data 212 includes several line electrode display data, such as the first to m-th line electrode display data 2121 to 212m. These several line electrode display data include at least one first line electrode display data 2121, which contains the type of line drive signal waveform for the first line electrode, while the second line electrode display data 2122 contains the type of line drive signal waveform for the second line electrode. In this embodiment, the first line electrode display data is the value of the first to third scan output terminals (scan 0 to scan 0), for example... Figure 22 As shown, the data displayed by the first line electrode is 2121, which is 111. Similarly, the data displayed by the second line electrode is the value from the first to third scan output terminals (scan 0 to scan 5), for example... Figure 22 As shown, the second line electrode displays data 2122 as 000.

[0142] Please see again Figures 23A to 23C As shown, the driving circuit unit 20 determines the signal waveform of a first line drive signal 2001 output to the first line electrode based on the first line electrode display data 2121. For example, if the first line electrode display data 2121 is 111, the driving circuit unit 20 determines that the signal waveform of the first line drive signal 2001 output to the first line electrode is to first output the sixth voltage V6, then output the third voltage V3, and the output duration of the sixth voltage V6 is 1:1 with the output duration of the third voltage V3. For example, the waveform of the first line drive signal 2001 output by the driving circuit unit 20 to the first line electrode... Figure 23A As shown, the drive circuit unit 20 outputs a line drive signal with the sixth voltage V6 to the first line electrode between the first to seventh count signals 102 output from the digital-to-analog conversion control terminal (d2a), and outputs a line drive signal with the third voltage V3 to the first line electrode between the eighth to fourteenth count signals 102 output from the digital-to-analog conversion control terminal (d2a).

[0143] Furthermore, the drive circuit unit 20 determines the waveform of a second line drive signal 2002 output to the second line electrode based on the second line electrode display data 2122. For example, if the second line electrode display data 2122 is 000, the drive circuit unit 20 determines that the waveform of the second line drive signal 2002 output to the second line electrode is to first output the second voltage V2, then output the fifth voltage V5, and the output duration ratio of the second voltage V2 and the fifth voltage V5 is 1:1. For instance, the waveform of the second line drive signal 2002 output by the drive circuit unit 20 to the second line electrode... Figure 23B As shown, the drive circuit unit 20 outputs a line drive signal with the second voltage V2 to the second line electrode between the first to the seventh count signals 102 output from the digital-to-analog conversion control terminal (d2a), and outputs a line drive signal with the fifth voltage V5 to the second line electrode between the eighth to the fourteenth count signals 102 output from the digital-to-analog conversion control terminal (d2a).
