Abstract
Description
[Technical Field]
[0001] A display, particularly a multistable display with handwriting functionality. [Previous Technology]
[0002] A conventional multistable display, such as a cholesterol liquid crystal display (ChLCD), has bistable liquid crystal display characteristics. Therefore, when displaying an image, this multistable display requires multiple voltage configurations for driving. For example, this multistable display has a display panel unit, and each pixel of the display panel unit is composed of a plurality of pixel electrodes and a plurality of line electrodes, and a liquid crystal layer is disposed between the line electrodes and the pixel electrodes. When driving the display panel unit, a voltage is applied to the line electrodes and the pixel electrodes, so that a specific voltage is applied at the position of the corresponding pixel, causing the liquid crystal in the liquid crystal layer to rotate to a specific angle.
[0003] 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 driving voltage to the line electrodes and the pixel electrodes according to the timing control signal, thereby driving the multistable display to display a specific image.
[0004] 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), complex data output terminals (data 0~n), and complex scan output terminals (scan 0~m). 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), the display start signal control terminal (dsp), the data output terminals (data 0~n), and the scan output terminals (scan 0~m) of the timing control circuit unit (TCON) are connected to the driver circuit unit (Driver IC) to output the timing control signal.
[0005] However, this multi-stable display requires multiple voltage configurations to drive it. Therefore, in the timing control signal, the data used to control the voltage configuration of each pixel needs to be transmitted through multiple bits, making it impossible to express multiple voltage configurations 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.
[0006] Please refer to Figures 7A and 7B. For example, the timing control circuit unit has three data output terminals (data 0~2) and three scan output terminals (scan 0~2). Taking a multistable display with a resolution of 1000 as an example, the three data output terminals (data 0~2) output a data signal 11a to the driving circuit unit, and the data signal 11a contains four sets of pixel electrode data (pixel 1~4), which the driving circuit unit uses to generate corresponding pixel electrode driving signals to the four pixel electrodes of the display panel unit. The three scan output terminals (scan 0~2) output a scan signal 12a to the driving circuit unit, and the scan signal 12a contains four sets of line electrode data (line 1~4), which the driving circuit unit uses to generate corresponding line electrode driving signals to the four line electrodes of the display panel unit.
[0007] In handwriting mode, each pixel electrode data transmitted by the timing control circuit is 3 bits. For example, a first pixel electrode data (pixel 1) has 3 bits: pixel 1 (0) to pixel 1 (2). As shown in Figure 7A, since the timing control circuit unit has 3 data output terminals, the timing control circuit unit can only output 1 pixel electrode data at a time, and 4 pixel electrode data (pixel 1 to 4) need to be transmitted in 4 steps. Similarly, as shown in Figure 7B, 4 line electrode data (line 1 to line 4) also need to be transmitted in 4 steps.
[0008] It can be seen that when the timing control circuit unit outputs the pixel electrode data and the line electrode data to the driving circuit unit, it needs to be transmitted in multiple steps, which is quite time-consuming and results in low data transmission efficiency. [Summary of the Invention]
[0009] In view of the fact that the data transmission of existing multistable displays is quite time-consuming, resulting in low data transmission efficiency, the present invention provides a multistable display with handwriting function to reduce the amount of data transmission in handwriting mode, thereby improving data transmission efficiency.
[0010] The multistable display with handwriting function includes a timing control circuit unit (TCON), a driver circuit unit (Driver IC) and a display panel unit.
[0011] The timing control signal includes a digital-to-analog conversion signal, a data signal and a scan signal, and the data signal sequentially includes handwritten pixel electrode header data and handwritten pixel electrode waveform data, while the scan signal sequentially includes handwritten line electrode header data and handwritten line electrode waveform data.
[0012] When the driving circuit unit receives the digital-to-analog conversion signal, the driving circuit unit generates a pixel electrode driving signal output to the display panel unit based on the handwritten pixel electrode header data and the handwritten pixel electrode waveform data, and the driving circuit unit generates a line electrode driving signal output to the display panel unit based on the handwritten line electrode header data and the handwritten line electrode waveform data.
[0013] When the driving circuit unit receives the digital-to-analog conversion signal, the driving circuit generates the pixel electrode driving signal output to the display panel unit using the handwritten pixel electrode header data and the handwritten pixel electrode waveform data. Therefore, the driving circuit unit can determine the voltage value of the pixel electrode driving signal input to the display panel unit based on a smaller number of bits of the handwritten pixel electrode waveform data, in conjunction with the handwritten pixel electrode header data, without directly transmitting 3 bits of voltage data. Similarly, the driving circuit unit generates the line electrode driving signal output to the display panel unit based on the handwritten line electrode header data and the handwritten line electrode waveform data. Therefore, the driving circuit unit can also determine the voltage value of the line electrode driving signal input to the display panel unit based on a smaller number of bits of the handwritten line electrode waveform data, in conjunction with the handwritten line electrode header data, without directly transmitting 3 bits of voltage data. Since the multistable display with handwriting function of the present invention only needs to use fewer bits to complete the data transmission, the amount of data transmission in handwriting mode can be reduced, thereby reducing the data transmission time and improving the data transmission efficiency.
Implementation Method
[0014] Please refer to Figure 1. The multistable display of the present invention includes a timing control circuit unit 10, a driving circuit unit 20 and a display panel unit 30.
[0015] 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 display panel unit 30 is connected to the drive circuit unit 20.
[0016] In this 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 of a conventional multi-stable display, and will not be described in detail here. In addition, the timing control circuit unit 10 also includes a plurality of data output terminals, such as the first to the (n+1)th data output terminals (data 0 to data n), and a plurality of scan output terminals, such as the first to the (m+1)th scan output terminals (scan 0 to scan m).
[0017] Referring to Figure 2, the display panel unit 30 has a plurality of pixel electrodes 31 and a plurality of line electrodes 32. Each pixel electrode 31 and each line electrode 32 forms a pixel at one of their intersection positions.
[0018] Please refer to Figures 3A to 3C. The timing control signal includes a digital-to-analog conversion signal, a data signal 11, and a scan signal 12. The data signal sequentially includes handwritten pixel electrode header data 111 and handwritten pixel electrode waveform data 112, while the scan signal 12 sequentially includes handwritten line electrode header data 121 and handwritten line electrode waveform data 122. In this embodiment, the timing control circuit unit includes a digital-to-analog conversion control terminal (d2a), which is connected to the driving circuit unit 20 and outputs the digital-to-analog conversion signal to the driving circuit unit 20.
[0019] When the driving circuit unit 20 receives the digital-to-analog conversion signal, the driving circuit unit 20 generates a pixel electrode driving signal output to the display panel unit 30 based on the handwritten pixel electrode header data 111 and the handwritten pixel electrode waveform data 112, and the driving circuit unit 20 generates a line electrode driving signal output to the display panel unit 30 based on the handwritten line electrode header data 121 and the handwritten line electrode waveform data 122.
[0020] When the driving circuit unit 20 receives the digital-to-analog conversion signal, it generates the pixel electrode driving signal output to the display panel unit 30 using the handwritten pixel electrode header data 111 and the handwritten pixel electrode waveform data 112. Therefore, the driving circuit unit 20 can determine the voltage value of the pixel electrode driving signal input to the display panel unit 30 based on the handwritten pixel electrode waveform data 112 (which has fewer bits) and the handwritten pixel electrode header data 111, without directly transmitting 3 bits of voltage data. Similarly, the driving circuit unit 20 generates the line electrode driving signal output to the display panel unit 30 based on the handwritten line electrode header data 121 and the handwritten line electrode waveform data 122. Therefore, the driving circuit unit 20 can also determine the voltage value of the line electrode driving signal input to the display panel unit 30 based on the handwriting line electrode waveform data 122 (which has fewer bits) and the handwriting line electrode header data 121, without directly transmitting 3 bits of voltage data. Since the multistable display with handwriting function of the present invention only needs to use fewer bits to complete data transmission, the amount of data transmission in handwriting mode can be reduced, thereby reducing data transmission time and improving data transmission efficiency.
[0021] In this embodiment, the handwritten pixel electrode waveform data 112 of the data signal 11 is 1 bit of data, and the handwritten line electrode waveform data 122 of the scan signal 12 is 1 bit of data.
[0022] Furthermore, the timing control circuit unit 10 also includes a header setting control terminal (dsh), which is connected to the drive circuit unit 20 to output a header setting signal 101 to the drive circuit unit 20. The data output terminals (data 0~data n) are connected to the drive circuit unit 20 to output the data signal 11 to the drive circuit unit 20. When the data output terminals (data 0~data n) output the data signal 11 as the handwritten pixel electrode header data 111, the header setting signal 101 output by the header setting control terminal (dsh) is a high voltage level. When the data output terminals (data 0~data n) output the data signal 11 as a non-handwritten pixel electrode header data 111, the header setting signal 101 output by the header setting control terminal (dsh) is a low voltage level.
[0023] Similarly, these scan output terminals (scan 0~scan m) are connected to the drive circuit unit 20 to output the scan signal 12 to the drive circuit unit 20. When the scan output terminal (scan 0~scan m) outputs the scan signal 12 as the handwriting line electrode header data 121, the header setting control terminal (dsh) outputs the header setting signal 101 as the high voltage level. When the scan output terminal (scan 0~scan m) outputs the scan signal 12 as not being the handwriting line electrode header data 121, the header setting control terminal (dsh) outputs the header setting signal 101 as the low voltage level.
[0024] Preferably, the data output terminals (data 0~data n) and the scan output terminals (scan 0~scan m) synchronously output the handwritten pixel electrode header data 111 and the handwritten circuit electrode header data 121.
[0025] Furthermore, the data signal 11 also includes pixel electrode blank data 113, which is followed by the handwritten pixel electrode waveform data 112. The scan signal 12 also includes line electrode blank data 123 in sequence, which is followed by the handwritten line electrode waveform data 122.
[0026] For example, please refer to Figures 4A and 4B. The timing control circuit unit 10 has three data output terminals (data 0~2) and three scan output terminals (scan 0~2). As shown in Figure 5, taking a multistable display with a resolution of 1000 as an example, the three data output terminals (data 0~2) output four sets of pixel electrode data (pixel 1~4) to the driving circuit unit 20, so that the driving circuit unit 20 can generate corresponding pixel electrode driving signals to the four pixel electrodes of the display panel unit 30 based on the four sets of pixel electrode data (pixel 1~4). The three scan output terminals (scan 0~2) output four sets of line electrode data (line 1~4) to the driving circuit unit 20, so that the driving circuit unit 20 can generate corresponding line electrode driving signals to the four line electrodes of the display panel unit 30 based on the four sets of line electrode data (line 1~4).
[0027] Furthermore, the handwritten pixel electrode header data 111 of the data signal 11 includes a first pixel electrode voltage data 1111 and a second pixel electrode voltage data 1112. For example, the bit data of the first pixel electrode voltage data 1111 output by the data output terminals (data 0~2) are V2(0), V2(1), and V2(2). And the bit data of the second pixel electrode voltage data 1112 output by the data output terminals (data 0~2) are V5(0), V5(1), and V5(2).
[0028] Furthermore, the handwritten line electrode header data 121 of the scan signal 12 includes a first line electrode voltage data 1211 and a second line electrode voltage data 1212. For example, the bit data of the first line electrode voltage data 1211 output by the scan output terminals (scan 0~2) are V5(0), V5(1), and V5(2). And the bit data of the second line electrode voltage data 1212 output by the scan output terminals (scan 0~2) are V2(0), V2(1), and V2(2).
[0029] Furthermore, the handwriting pixel electrode waveform data 112 of the data signal 11 is 1-bit data, and the handwriting line electrode waveform data 122 of the scan signal 12 is 1-bit data. Since in a handwriting mode, handwriting input represents the generation of a trajectory, and the trajectory is represented by a single color, as shown in Figure 5, when a user performs handwriting input at the lower left position, the display panel unit 30 needs to update the pixel corresponding to that position to a colored state, while the other positions remain colorless. For example, the pixel at the lower left position is the intersection of the first pixel electrode 31 (pixel 1) and the first line electrode 32 (line 1). Therefore, the number of bits in the handwriting pixel electrode waveform data 112 corresponding to the first pixel electrode 31 (pixel 1) and the number of bits in the handwriting line electrode waveform data 122 corresponding to the first line electrode 32 (line 1) are set to a first bit value, such as bit 1, and the rest are set to a second bit value, such as bit 0. For example, as shown in Figure 4A, pixel 1 (0) is set to 1, and as shown in Figure 4B, line 1 (0) is set to 1, indicating that the pixel at the intersection of pixel 1 (0) and line 1 (0) has handwritten input and needs to be updated to a colored state. The remaining pixels 2~4 (0) and lines 2~4 (0) are all set to 0, indicating that no update is needed and the state is without color.
[0030] Please refer further to Figures 6A to 6F. As shown in Figure 6D, the pixel electrode driving signal 201 has a first pixel electrode half-cycle 201a and a second pixel electrode half-cycle 201b.
[0031] As shown in Figures 6B and 6D, when the driving circuit unit 20 receives the first digital-to-analog conversion signal 102, the driving circuit unit 20 outputs the pixel electrode driving signal 201 as the first pixel electrode half-cycle 201a. And when the driving circuit unit 20 receives the second digital-to-analog conversion signal 102, the driving circuit unit 20 outputs the pixel electrode driving signal 201 as the second pixel electrode half-cycle 201b.
[0032] Further, referring to Figures 6C and 6D, the handwritten pixel electrode header data 111 of the data signal 11 includes the first pixel electrode voltage data 1111 and the second pixel electrode voltage data 1112. When the handwritten pixel electrode waveform data 112 of the data signal 11 is the first digital value, and when the pixel electrode driving signal 201 output by the driving circuit unit 20 is the first pixel electrode half-cycle 201a, the driving circuit unit 20 generates the pixel electrode driving signal 201 based on the first pixel electrode voltage data 1111 of the handwritten pixel electrode header data 111. In this embodiment, when the pixel electrode driving signal 201 output by the driving circuit unit 20 is the first pixel electrode half-cycle 201a, the voltage value of the pixel electrode driving signal 201 generated by the driving circuit unit 20 is the second voltage V2 in the first pixel electrode voltage data 1111.
[0033] When the handwritten pixel electrode waveform data 112 of the data signal 11 is the first digital value, and when the pixel electrode driving signal 201 output by the driving circuit unit 20 is the second pixel electrode half-cycle 201b, the driving circuit unit 20 generates the pixel electrode driving signal 201 based on the second pixel electrode voltage data 1112 of the handwritten pixel electrode header data 111. In this embodiment, when the pixel electrode driving signal 201 output by the driving circuit unit 20 is the second pixel electrode half-cycle 201b, the voltage value of the pixel electrode driving signal 201 generated by the driving circuit unit 20 is the fifth voltage V5 in the second pixel electrode voltage data 1112.
[0034] Furthermore, as shown in FIG6F, the line electrode drive signal 202 has a first line electrode half-cycle 202a and a second line electrode half-cycle 202b.
[0035] As shown in Figures 6B and 6F, when the driving circuit unit 20 receives the first digital-to-analog conversion signal 102, the driving circuit unit 20 outputs the line electrode driving signal 202 as the first line electrode half-cycle 202a. When the driving circuit unit 20 receives the second digital-to-analog conversion signal 102, the driving circuit unit 20 outputs the line electrode driving signal 202 as the second line electrode half-cycle 202b.
[0036] Further, referring to Figures 6E and 6F, the handwritten line electrode header data 121 of the scan signal 12 includes the first line electrode voltage data 1211 and the second line electrode voltage data 1212. When the handwritten line electrode waveform data 122 of the scan signal 12 is the first digital value, and when the line electrode drive signal 202 output by the drive circuit unit 20 is the first line electrode half-cycle 202a, the drive circuit unit 20 generates the line electrode drive signal 202 based on the first line electrode voltage data 1211 of the handwritten line electrode header data 121. In this embodiment, when the line electrode drive signal 202 output by the drive circuit unit 20 is the first line electrode half-cycle 202a, the voltage value of the line electrode drive signal 202 generated by the drive circuit unit 20 is the fifth voltage V5 in the first line electrode voltage data 1211.
[0037] When the handwritten line electrode waveform data 122 of the scan signal 12 is the first digital value, and when the line electrode drive signal 202 output by the drive circuit unit 20 is the second line electrode half-cycle 202b, the drive circuit unit 20 generates the line electrode drive signal 202 based on the second line electrode voltage data 1212 of the handwritten line electrode header data 121. In this embodiment, when the line electrode drive signal 202 output by the drive circuit unit 20 is the second line electrode half-cycle 202b, the voltage value of the line electrode drive signal 202 generated by the drive circuit unit 20 is the second voltage V2 in the second line electrode voltage data 1212.
[0038] Furthermore, in this embodiment, as shown in Figures 6B and 6C or 6E, the driving circuit unit 20 outputs the digital-to-analog conversion signal 102 to the driving circuit unit 20 during the period when the data signal 11 is the pixel electrode blank data 113. Alternatively, the driving circuit unit 20 outputs the digital-to-analog conversion signal 102 to the driving circuit unit 20 during the period when the data signal 11 is the line electrode blank data 123.
[0039] Furthermore, in the multistable display device with local update mode of the present invention, the counting signal of the digital-to-analog conversion signal 102 output by the digital-to-analog conversion control terminal (d2a) is used to allow the driving circuit unit 20 to determine whether the pixel electrode driving signal 201 is the first pixel electrode half-cycle 201a or the second pixel electrode half-cycle 201b. Therefore, the data output terminals only need to complete the transmission of waveform data before the rising edge of the first counting signal. That is, after the waveform data is output, the data output terminals do not need to output the waveform data again. In this way, during the period when the counting signal 102 is output by the digital-to-analog conversion control terminal (d2a), the data output terminals do not need to output the waveform data. For example, as shown in Figures 6B and 6C, when the digital-to-analog conversion control terminal (d2a) outputs the counting signal 102, the data output terminals output the pixel electrode blank data 113. The blank data 113 of the pixel electrode indicates that there is no output data from these data output terminals. Therefore, during the counting period when the digital-to-analog conversion control terminal (d2a) outputs the counting signal 102, these data output terminals do not need to transmit waveform data.
