Abstract
Description
Technical Field
[0001] This invention relates to a display, and more particularly to a 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 multiple scan electrodes and multiple data electrodes, and a liquid crystal layer is disposed between the scan electrodes and the data electrodes. When driving the panel unit, a voltage is applied to the scan electrodes and the data 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 includes a timing controller (TCON) and a driver IC. The timing controller generates a timing control signal to the driver IC, which outputs a drive voltage to the scan electrode and the data electrode according to the control signal, thereby driving the multistable display to display a specific image.
[0005] Generally, the timing control circuit unit (TCON) 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 (display start pulse; dsp), and multiple 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 data output terminals of the timing control circuit unit (TCON) 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 Full HD resolution, 1920×1080. When transmitting at 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 multi-stable display requires 3 bits of data to transmit. Furthermore, since each pixel requires 3 bits of data to transmit, 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] The clock rate of this multistable display can be calculated using the following formula:
[0008] Clock Rate (Hz)
[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 is adjustable as needed and can be set to 64, typically in powers of 2. Transmission time (T...) line The value is 5 milliseconds (ms). Substituting these figures into the formula yields Table 1, which shows the clock rate under various conditions.
[0011]
[0012]
[0013] Table 1
[0014] As shown in Table 1, under Full HD resolution, the clock rate of this multistable display is quite high, resulting in high power consumption and rapid power consumption. Summary of the Invention
[0015] In view of the fact that the clock frequency of existing multistable displays is quite high, resulting in high power consumption and rapid power consumption, the present invention provides a cholesteric liquid crystal device to reduce the clock frequency of multistable displays, thereby reducing power consumption.
[0016] The multi-stable display includes a timing control circuit unit (TCON), a driver circuit unit (DriverIC), and a panel unit.
[0017] The timing control circuit unit generates a timing control signal. The drive circuit unit stores a voltage configuration truth table, is connected to the timing control circuit unit, and receives the timing control signal. The panel unit is connected to the drive circuit unit.
[0018] The timing control signal includes a first data signal, which sequentially includes at least one header setting data and at least one voltage waveform data. When the drive circuit unit receives the header setting data, it sets the voltage configuration truth table according to the header setting data. When the drive circuit unit receives the voltage waveform data, it determines a drive voltage waveform to be output to the panel unit according to the voltage waveform data and the voltage configuration truth table.
[0019] When the drive circuit unit receives the voltage waveform data, it determines the drive voltage waveform to be output to the panel unit based on the voltage waveform data and the voltage configuration truth table. Therefore, the voltage waveform data can transmit 1 bit of data, allowing the drive circuit unit to look up the voltage configuration truth table based on this 1 bit of data to confirm the voltage value of the drive voltage waveform input to the panel unit, without directly transmitting the voltage value. Generally, the voltage value of the drive voltage waveform is used to control the voltage configuration and requires 3 bits to transmit. However, the voltage waveform data only requires 1 bit to complete the data transmission. Furthermore, the voltage configuration truth table is set according to the header setting data and can change the output voltage value as needed, achieving the goal of transmitting the same amount of data with fewer bits. Since the same amount of data can be transmitted using fewer bits, a lower clock rate can be used to reduce power consumption when transmitting the same amount of data in the same amount of time.

[0043] Please see Figure 1 As shown, the multistable display of the present invention includes a timing control circuit unit 10, a driving circuit unit 20, and a panel unit 30.
[0044] The timing control circuit unit 10 generates a timing control signal. The drive circuit unit 20 stores a voltage configuration truth table, 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.
[0045] Please refer to the following: Figure 2A and Figure 2B As shown, the timing control signal includes a first data signal 11, and the first data signal 11 sequentially includes at least one header setting data 111 and at least one voltage waveform data 112. When the drive circuit unit 20 receives the header setting data 111, the drive circuit unit 20 sets the voltage configuration truth table according to the header setting data 111. When the drive circuit unit 20 receives the voltage waveform data 112, the drive circuit unit 20 determines a drive voltage waveform to be output to the panel unit 30 according to the voltage waveform data 112 and the voltage configuration truth table.
[0046] Since the driving circuit unit 20 determines the driving voltage waveform output to the panel unit based on the voltage waveform data 112 and the voltage configuration truth table, the voltage waveform data 112 can transmit 1 bit of data, allowing the driving circuit unit to query the voltage configuration truth table based on this 1 bit of data and confirm the voltage value of the driving voltage waveform input to the panel unit 30, without directly transmitting the entire voltage value. Generally, the entire voltage value is transmitted using 3 bits, while the voltage waveform data only needs 1 bit to complete the voltage value transmission. Furthermore, the voltage configuration truth table is set according to the header setting data, and the output voltage value can be changed as needed to achieve the purpose of transmitting the same amount of data with fewer bits. Since the same amount of data can be transmitted using fewer bits, a lower clock rate can be used to reduce power consumption when transmitting the same amount of data in the same amount of time.
[0047] Furthermore, the at least one header setting data 111 includes a white header setting data 1111 and a content header setting data 1112, and the at least one voltage waveform data 112 includes a white voltage waveform data 1121 and a content voltage waveform data 1122. The first data signal 11 is composed of the white header setting data 1111, the white voltage waveform data 1121, the content header setting data 1112, and the content voltage waveform data 1122 arranged sequentially.
[0048] In this embodiment, the first data signal 11 further includes a hold time data 113 in sequence, and the hold time data 113 is located between the whitewash voltage waveform data 1121 and the content header setting data 1112. That is, the first data signal 11 can be composed of the whitewash header setting data 1111, the whitewash voltage waveform data 1121, the hold time data 113, the content header setting data 1112, and the content voltage waveform data 1122 arranged in sequence.
[0049] In detail, such as Figure 1As shown, 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 digital-to-analog conversion control terminal (digital to analog; d2a), 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), the digital-to-analog conversion control terminal (d2a), and the display start signal control terminal (dsp) of the timing control circuit unit (TCON) are the same as those of the timing control circuit units of existing multi-stable displays, and will not be described in detail here.
[0050] Furthermore, the timing control circuit unit 10 includes a header setting control terminal (dsh), a voltage positive / negative control terminal (dpn), and a first data output terminal (data 0). In other embodiments, the timing control circuit unit 10 may include multiple data output terminals (data 0 to data n), such as the first to the (n+1)th data output terminals (data 0 to data n). In this embodiment, the first data output terminal (data 0) is used as an example, but it is not a limitation thereof.
[0051] 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 voltage positive / negative control terminal (dpn) is connected to the drive circuit unit 20 and outputs a positive / negative signal 102 to the drive circuit unit 20. The first data output terminal (data 0) is connected to the drive circuit unit 20 and outputs the first data signal 11 to the drive circuit unit 20.
[0052] like Figure 2A and Figure 2B As shown, when the first data signal 11 output by the first data output terminal (data 0) is the white header setting data 1111, the header setting control terminal (dsh) outputs the header setting signal 101 at a high voltage level. And when the first data signal 11 output by the first data output terminal (data 0) is the content header setting data 1112, the header setting control terminal (dsh) outputs the header setting signal 101 at a high voltage level. However, when the first data signal 11 output by the first data output terminal (data 0) is neither the white header setting data 1111 nor the content header setting data 1112, the header setting control terminal (dsh) outputs the header setting signal 101 at a low voltage level.
[0053] When the header setting signal 101 output by the header setting control terminal (dsh) is at the high voltage level, it means that the first data signal 11 output by the first data output terminal (data 0) is either the white header setting data 1111 or the content header setting data 1112. At this time, the drive circuit unit 20 can determine that the currently received first data signal 11 is the header setting data 111, and then set the voltage configuration truth table according to the header setting data 111.
[0054] Please see Figure 3A and Figure 3B As shown, the brush white voltage waveform data 1121 sequentially includes a positive brush white voltage waveform data 1121+ and a negative brush white voltage waveform data 1121-. When the first data 11 output by the first data output terminal (data 0) is the positive brush white voltage waveform data 1121+, the positive / negative signal 102 output by the voltage positive / negative control terminal (dpn) is the high voltage level. Furthermore, since the first data signal 11 output by the first data output terminal (data 0) at this time does not belong to the brush white header setting data 1111 or the content header setting data 1112, the header setting signal 101 output by the header setting control terminal (dsh) is the low voltage level.
[0055] When the first data 11 output by the first data output terminal (data 0) is the negative brush white voltage waveform data 1121-, the positive and negative signal 102 output by the voltage positive and negative control terminal (dpn) is the low voltage level. Similarly, since the first data signal 11 output by the first data output terminal (data 0) at this time does not belong to the brush white header setting data 1111 or the content header setting data 1112, the header setting signal 101 output by the header setting control terminal (dsh) is the low voltage level.
[0056] Please see Figure 4A and Figure 4B As shown, the content voltage waveform data 1122 sequentially includes a positive content voltage waveform data 1122+ and a negative content voltage waveform data 1122-. When the first data 11 output by the first data output terminal (data 0) is the positive content voltage waveform data 1122+, the positive / negative signal 102 output by the voltage positive / negative control terminal (dpn) is the high voltage level. Furthermore, since the first data signal 11 output by the first data output terminal (data 0) at this time is neither the white label setting data 1111 nor the content label setting data 1112, the label setting signal 101 output by the label setting control terminal (dsh) is the low voltage level.
[0057] When the first data 11 output by the first data output terminal (data 0) is the negative content voltage waveform data 1122-, the positive and negative signal 102 output by the voltage positive and negative control terminal (dpn) is the low voltage level. Similarly, since the first data signal 11 output by the first data output terminal (data 0) at this time does not belong to the white label setting data 1111 or the content label setting data 1112, the label setting signal 101 output by the label setting control terminal (dsh) is the low voltage level.
[0058] Furthermore, in this embodiment, the voltage configuration truth table uses the first data signal 11 output from the first data output terminal (data 0) and the positive and negative signals 102 output from the voltage positive and negative control terminal (dpn) as inputs. And when the drive circuit unit 20 sets the voltage configuration truth table according to the header setting data 111, the header setting data 111 is set as the output of the voltage configuration truth table.
[0059] For example, consider a multistable display with Full HD resolution, which has a resolution of 1920×1080. When transmitting at Single Data Rate (SDR), 2 pixels of data are transmitted per clock cycle, meaning the number of pixels transmitted per clock cycle is 2. Furthermore, the transmission time (T) for each frame of data is set. line The time is 5 milliseconds (ms).
[0060] Since the driving circuit unit 20 determines the driving voltage waveform output to the panel unit based on the voltage waveform data 112 and the voltage configuration truth table, the voltage waveform data 112 can transmit 1 bit of data. That is, each pixel of the multistable display only requires 1 bit of data to be transmitted. Furthermore, the timing control circuit unit 10 already has one clock output (clk) and six control outputs (doe, dog, d2a, dsp, dsh, dpn). If the same number of outputs (Pin Count) is maintained, i.e., a total of 11 outputs are set, the number of data outputs (data) can be set to four, namely the first to fourth data outputs (data 0 to data 4).
[0061] Since each pixel's data only requires 1 bit to be transmitted, and the number of data output terminals is 4, the number of pixels transmitted per clock clock can be calculated to be 4, that is, 1×a=4, a=4, where the parameter a is the number of pixels transmitted per clock clock.
[0062] Furthermore, the clock rate of this multistable display is calculated using the same formula, as shown below:
[0063] Clock Rate (Hz)
[0064]
[0065] The resolution is 1920. The number of pixels transmitted per clock clock is 4 at Single Data Rate (SDR). The hold time is set to 1. The duty count is adjustable as needed and can be set to 4, 8, 16, 32, 64… in powers of 2. The transmission time (T…) is… line The value is 5 milliseconds (ms). Substituting these figures into the formula yields Table 2, which shows the clock rate under various conditions.
[0066]
[0067] Table 2
[0068] As can be seen from the comparison in Tables 1 and 2, the clock rate of the multistable display of the present invention can be directly reduced by half under the same conditions. In this way, the multistable display can adopt a low-frequency driving scheme, thereby effectively reducing power consumption.
[0069] For details, please refer to Figures 5A to 5C As shown, since the header setting data 111 is set as the output of the voltage configuration truth table, the white-brush header setting data 1111 contains four output values output(1) to output(4). Furthermore, since the voltage value of a typical multi-stable display is transmitted using three bits, each output value output(1) to output(4) is three bits of data. For example... Figure 5B and 5C As shown, a first output value output(1) has three bits of data, namely V1(0), V1(1), and V1(2), which are used to represent the first voltage V1, and so on. In addition, the voltage configuration truth table is based on the first data signal 11 output from the first data output terminal (data 0) and the positive and negative signals 102 output from the voltage positive and negative control terminal (dpn) as inputs, so the voltage configuration truth table shown in Table 3 below can be obtained.
[0070]
[0071] Table 3
[0072] Furthermore, the voltage used for whitening in this multi-stable display will be the maximum positive voltage and the maximum negative voltage. For example, the maximum positive voltage is the first voltage V1, and the maximum negative voltage is the fourth voltage V4. Therefore, the output of the voltage configuration truth table set by the whitening head setting data 1111 only needs the first voltage V1 and the fourth voltage V4. Thus, the four output values output(1) to output(4) in the whitening head setting data 1111 are the first and second output values output(1) and (2) set to the first voltage V1, and the third and fourth output values output(3) and (4) set to the fourth voltage V4.
[0073] Furthermore, please refer to Figures 6A to 6D As shown, the brush white voltage waveform data 1121 includes the positive brush white voltage waveform data 1121+ and the negative brush white voltage waveform data 1121-. Furthermore, the positive brush white voltage waveform data 1121+ and the negative brush white voltage waveform data 1121- also each have a first pixel data 1121a and a second pixel data 1121b. The first pixel data 1121a is used to drive a first pixel of the panel unit 30, and the second pixel data 1121b is used to drive a second pixel of the panel unit 30.
[0074] However, according to the truth table of the voltage configuration in Table 3, since the first and second output values output(1) and (2) are set to the first voltage V1, and the third and fourth output values output(3) and (4) are set to the fourth voltage V4, therefore, as Figure 6D As shown, regardless of the first data signal 11 output by the first data output terminal (data 0), as long as the positive and negative signal 102 output by the voltage positive and negative control terminal (dpn) is set to the high voltage level, i.e., the digital 1, the driving voltage waveform output by the driving circuit unit 20 to the panel unit 30 can be controlled to be the first voltage V1. Similarly, as Figure 6D As shown, when the positive and negative signal 102 output by the voltage positive and negative control terminal (dpn) is set to the low voltage level, i.e., digital 0, the driving voltage waveform output by the driving circuit unit 20 to the panel unit 30 can be controlled to be the first voltage V1.
[0075] to this end, Figure 6C In this context, X represents the first data signal 11 output by the first data output terminal (data 0). No matter how it is set, it will not affect the driving voltage waveform output by the driving circuit unit 20 to the panel unit 30.
[0076] In addition, please see Figures 7A to 7CAs shown, the header setting data 1112 also contains four output values, output(1) to output(4). Similarly, since the voltage value is transmitted using 3 bits, each output value, output(1) to output(4), is 3 bits of data. For example... Figure 7B and 7C As shown, the first output value output(1) has three bits of data, namely V2(0), V2(1), and V2(2), which are used to represent the second voltage V2. The others are represented in the same way, representing the third voltage V3, the fifth voltage V5, and the sixth voltage V6, respectively. In addition, the voltage configuration truth table is based on the first data signal 11 output from the first data output terminal (data 0) and the positive and negative signals 102 output from the voltage positive and negative control terminal (dpn) as inputs. Therefore, the voltage configuration truth table shown in Table 4 below can be obtained.
[0077]
[0078] Table 4
[0079] Furthermore, the driving voltage used by the multi-stable display to display content has four voltage configurations, such as the second voltage V2, the third voltage V3, the fifth voltage V5, and the sixth voltage V6. Therefore, the output of the voltage configuration truth table set by the content header setting data 1112 has the second voltage V2, the third voltage V3, the fifth voltage V5, and the sixth voltage V6. Thus, the four output values output(1) to output(4) in the content header setting data 1112 are: the first output value output(1) is set to the second voltage V2, the second output value output(2) is set to the third voltage V3, the third output value output(3) is set to the fifth voltage V5, and the fourth output value output(4) is set to the sixth voltage V6.
[0080] Furthermore, please refer to Figures 8A to 8D As shown, the content voltage waveform data 1122 includes the positive content voltage waveform data 1122+ and the negative content voltage waveform data 1122-. Furthermore, the positive content voltage waveform data 1122+ and the negative content voltage waveform data 1122- also each have a first pixel data 1122a and a second pixel data 1122b. The first pixel data 1122a is used to drive the first pixel of the panel unit 30, and the second pixel data 1122b is used to drive the second pixel of the panel unit 30.
[0081] For example, according to the truth table of this voltage configuration in Table 4, as follows: Figure 8C and Figure 8DAs shown, when the first pixel data 1122a of the first data signal 11 output by the first data output terminal (data 0) is at the high voltage level, i.e., the digit 1, and when the positive and negative signal 102 output by the voltage positive and negative control terminal (dpn) is also at the high voltage level, i.e., the digit 1, the driving voltage waveform output by the driving circuit unit 20 to the panel unit 30 is the second voltage V2. Similarly, when the second pixel data 1122b of the first data signal 11 output by the first data output terminal (data 0) is at the low voltage level, i.e., the digit 0, and when the positive and negative signal 102 output by the voltage positive and negative control terminal (dpn) is at the high voltage level, i.e., the digit 1, the driving voltage waveform output by the driving circuit unit 20 to the panel unit 30 is the third voltage V3.
[0082] In this way, the drive circuit unit 20 can set the voltage configuration truth table, such as Tables 3 and 4, according to the white label setting data 1111 and the content label setting data 1112, respectively. Furthermore, the drive circuit unit 20 can also determine the drive voltage waveform output to the panel unit 30 based on the white label voltage waveform data 1121, the content voltage waveform data 1122, and the voltage configuration truth table, such as Tables 3 and 4. Figure 9A and Figure 9B As shown, Figure 9A This is a waveform diagram of the driving voltage waveform 201 output by the driving circuit unit 20 to the first pixel. Figure 9B This is a waveform diagram of the driving voltage waveform 202 output by the driving circuit unit 20 to the second pixel.
