Description

Technical Field

[0001] This case relates to a driving device, and more particularly to a panel driving device. Background Technology

[0002] Currently, the voltage used to drive the liquid crystal in the panel comes from the voltage difference between the reference voltage (e.g., common electrode voltage) and the voltage used to write the pixels.

[0003] With the increasing demand for gaming products, the voltage used to write pixels is often increased to raise the voltage driving the liquid crystal, which in turn causes the panel's wattage to rise significantly. Summary of the Invention

[0004] The present invention is intended to provide a simplified summary of this disclosure to enable the reader to have a basic understanding of it. This summary is not a complete overview of the present disclosure and is not intended to identify key / critical elements of the embodiments or define the scope of the invention.

The data lines are used to transmit data signals. The reference electrode lines are used to transmit reference signals. The first pixel is used to receive the data signals and the reference signals. The first pixel generates a pixel signal based on the data signals and the reference signals. During a positive frame, the difference between a first voltage value of the pixel signal and a first reference voltage value of the reference signal is a first driving voltage value. During a negative frame, the difference between a second voltage value of the pixel signal and a second reference voltage value of the reference signal is a second driving voltage value. The negative frame period follows the positive frame period, and the absolute values ​​of the first and second driving voltage values ​​are approximately the same. During a charging period between the negative and positive frame periods, the pixel signal has a third voltage value greater than the second voltage value and less than or equal to the first voltage value.

[0156] Figure 1A This is a block diagram illustrating a panel driving device according to an embodiment of this case. Figure 1A As shown, in some embodiments, the panel driving device 100 includes a panel 110. The panel 110 includes a data line 111, a reference electrode line 112, and a first pixel 113. In terms of connection, the data line 111 is coupled to the first pixel 113, and the reference electrode line 112 is coupled to the first pixel 113.

[0157] For example, panel 110 can be any type of light-emitting diode panel, such as a micro light-emitting diode (Micro LED) panel, a mini LED panel, or an organic light-emitting diode (OLED) panel, but this application is not limited thereto.

[0158] Figure 1B This is a block diagram illustrating pixels of a panel driving device according to an embodiment of this case. Figure 1A As shown, in some embodiments, the first pixel 113A includes element U11, element U12, and node U13. In terms of connection, data line 111A is coupled to element U11 of the first pixel 113A, reference electrode line 112A is coupled to element U12 of the first pixel 113A, and elements U11 and U12 are coupled to node U13.

[0159] For example, element U11 can be a switching element, such as any type of transistor. Element U11 can output a signal (e.g., data signal SD) based on the gate signal SG and the data signal SD. Element U12 can be any type of capacitor. Element U12 can receive and output a signal (e.g., reference signal SC) based on the reference signal SC. The user can measure the pixel signal at node U13, but this application is not limited thereto.

[0160] In some embodiments, data line 111A is used to transmit data signal SD. Reference electrode line 112A is used to transmit reference signal SC. First pixel 113A is used to receive data signal SD and reference signal SC.

[0161] For example, the reference electrode line 112A can be a common electric electrode, and the reference signal SC can be a common voltage (Vcom), but this application is not limited to this.

[0162] In some embodiments, the first pixel 113A receives and generates a pixel signal based on the data signal SD and the reference signal SC.

[0163] For example, node U13 of the first pixel 113A can form a pixel signal by electrical coupling of data signal SD and reference signal SC, but this application is not limited to this.

[0164] In some embodiments, Figure 1B Data cable 111A can correspond to Figure 1A Data cable 111, Figure 1B The reference electrode line 112A can correspond to Figure 1A Reference electrode line 112, Figure 1B The first pixel 113A can correspond to Figure 1A The first pixel is 113, but this case is not limited to this.

[0165] Figure 2A This is a usage scenario diagram illustrating a panel driving device according to an embodiment of this case. For example... Figure 2A As shown, in some embodiments, the pixel signal has a first voltage value V11 and a second voltage value V0, and the reference signal has a first reference voltage value VC11 and a second reference voltage value VC12. A first driving voltage dv1 is present between the first voltage value V11 and the second reference voltage value VC12, and a second driving voltage dv2 is present between the second voltage value V0 and the first reference voltage value VC11.

[0166] For example, the first voltage value V11 can be 7 volts (Volt, V), the second voltage value V0 can be 0 volts, the first reference voltage value VC11 can be 5 volts, the second reference voltage value VC12 can be 2 volts, the first driving voltage dv1 can be 5 volts, and the second driving voltage dv2 can be 5 volts, but this case is not limited to these.

[0167] In some embodiments, Figure 2A The pixel signal can correspond to Figure 1B pixel signals, Figure 2A The reference signal can correspond to Figure 1B The reference signal SC is used, but this case is not limited to it.

[0168] In some embodiments, during the positive frame polarity (+Frame) period, the first voltage value V11 can be the voltage value of the positive polarity grayscale 255 (+L255), and the second reference voltage value VC12 can be the positive polarity common voltage value (+Vcom).

[0169] In some embodiments, during negative frame polarity (-Frame), the second voltage value V0 can be the voltage value of negative polarity grayscale 255 (-L255), and the first reference voltage value VC11 can be the negative polarity common voltage value (-Vcom).

[0170] Please refer to the following: Figure 1A and Figure 2A In some embodiments, conventional panels are designed with only one common voltage value. During the positive frame polarity period, the liquid crystal driving voltage (Vlc) can be the difference between the voltage value of the positive grayscale 255 (e.g., 10 volts) and the common voltage value (e.g., 5 volts). During the negative frame polarity period, the liquid crystal driving voltage can be the difference between the voltage value of the negative grayscale 255 (-L255) (e.g., 0 volts) and the common voltage value (e.g., 5 volts). Therefore, the liquid crystal driving voltage can be 5 volts.

[0171] However, the panel 110 in this case can have two common voltage values, for example, a first reference voltage value VC11 and a second reference voltage value VC12. During the positive frame polarity (+Frame), the voltage value of the positive grayscale 255 (+L255) can be 7 volts, and one of the two common voltage values ​​can be 2 volts. During the negative frame polarity (-Frame), the voltage value of the negative grayscale 255 (-L255) can be 0 volts, and one of the two common voltage values ​​can be 5 volts. At this time, the driving voltage of the liquid crystal can be 5 volts.

[0172] In summary, this solution can reduce the operating voltage (e.g., the voltage value of positive grayscale 255) by setting two shared voltage values ​​for +Frame and -Frame, thereby achieving the effect of reducing wattage (Low Power).

[0173] Figure 2B This is a usage scenario diagram illustrating a panel driving device according to an embodiment of this case. For example... Figure 2B As shown, in some embodiments, the pixel signal has a first voltage value V21 and a second voltage value V0, and the reference signal has a first reference voltage value VC21 and a second reference voltage value VC22. A first driving voltage dv3 is present between the first voltage value V11 and the second reference voltage value VC12, and a second driving voltage dv4 is present between the second voltage value V0 and the first reference voltage value VC11.

[0174] For example, the first voltage value V21 can be 10 volts, the second voltage value V0 can be 0 volts, the first reference voltage value VC21 can be 8 volts, the second reference voltage value VC22 can be 2 volts, the first driving voltage dv3 can be 8 volts, and the second driving voltage dv4 can be 8 volts. Furthermore, Figure 2B Operation of mid-pixel signals and reference signals Figure 2A The operation of the mid-pixel signal and the reference signal is similar; for the sake of simplicity, details regarding them will be omitted here. Figure 2B Description of other operations.

[0175] Please refer to the following: Figure 1A and Figure 2B In some embodiments, the voltage value of the positive grayscale 255 of a conventional panel can be 10 volts, the common voltage value can be 5 volts, and the driving voltage of the liquid crystal can be 5 volts. However, in this case, the voltage value of the positive grayscale 255 of the panel 110 can be 10 volts, one of the two common voltage values ​​can be 2 volts, and the driving voltage of the liquid crystal can be 8 volts.

[0176] In summary, when this invention has the same positive polarity grayscale voltage value of 255 as a traditional panel, it can have a larger liquid crystal driving voltage compared to the traditional panel, thus achieving the effect of improving the liquid crystal driving voltage.

[0177] Figure 3 This is a schematic diagram illustrating the structure of a panel driving device according to an embodiment of this case. Figure 3 As shown, in some embodiments, panel 300 includes a plurality of data lines 111B, 111C, a plurality of reference electrode lines 112B, 112C, 112D, 112E and a plurality of pixels 113B, 113C.

[0178] In some embodiments, during the positive frame interval, Figure 3 The "+" sign can be considered positive, and the "-" sign can be considered negative. In the negative frame region, Figure 3 The polarities of "+" and "-" in Chinese are reversed, but this case is not limited to this.

[0179] In some embodiments, Figure 3 Panel 300 corresponds Figure 1A Panel 110, Figure 3 One of the multiple data lines 111B and 111C corresponds to Figure 1A Data cable 111 Figure 3 One of the multiple reference electrode lines 112B, 112C, 112D, and 112E corresponds to Figure 1A Reference electrode line 112, Figure 3 One of the multiple pixels 113B and 113C corresponds to Figure 1A The pixel count is 113, but this case is not limited to this.

[0180] Figure 4 This is a schematic diagram illustrating the structure of a panel driving device according to an embodiment of this case. Figure 4 As shown, in some embodiments, panel 400 includes a plurality of gates 9, 9A, a plurality of data lines 41, 41A, a plurality of reference electrode lines 42, 42A, 42B, 42C and a plurality of pixels 43, 43A, 43B, 43C.

[0181] In some embodiments, Figure 4 The panel 400 can correspond to Figure 3 The panel size is 300, but this case is not limited to this.

[0182] Figure 5A This is a timing diagram illustrating multiple signals of a panel driving device according to an embodiment of this case. Figure 5A As shown, in some embodiments, Figure 5A It has a gate signal SG1, a data signal SD1, a reference signal SC1, and a pixel signal SP1.

[0183] For example, Figure 5A The gate signal SG1 can correspond to Figure 1B The gate signal SG, Figure 5A The data signal SD1 can correspond to Figure 1B Data signal SD, Figure 5A The reference signal SC1 can correspond to Figure 1B The reference signal SC, Figure 5A The pixel signal SP1 can correspond to Figure 1B The pixel signal measured by the middle node U13, but this case is not limited to this.

[0184] In some embodiments, the gate signal SG1 has a high-order voltage value and a low-order voltage value.

[0185] For example, the high-order voltage value of gate signal SG1 can be 30 volts, and the low-order voltage value of gate signal SG1 can be 0 volts. The high-order voltage value can be used to turn on element U11 (e.g., Figure 1B As shown), the low voltage value can be used to turn off component U11, but this is not the case.

[0186] In one embodiment, operatively, during a positive frame period P2, the difference between the first voltage value of the pixel signal SP1 and the first reference voltage value of the reference signal SC1 is the first driving voltage value.

[0187] For example, the positive frame period P2 can be the positive frame holding period, the first voltage value of the pixel signal SP1 can be 12 volts (V), the first reference voltage value of the reference signal SC1 can be 4 volts, and the first driving voltage value can be 12-4=8 volts, but this case is not limited to these.

[0188] Then, during the negative frame period P4, the difference between the second voltage value of pixel signal SP1 and the second reference voltage value of reference signal SC1 is the second driving voltage value.

[0189] For example, the negative frame period P4 can be the negative frame holding period, the second voltage value of the pixel signal SP1 can be -4 volts, the second reference voltage value of the reference signal SC1 can be 4 volts, and the second drive voltage value can be 4 - (-4) = 8 volts, but this case is not limited to these.

[0190] Furthermore, during the negative frame period P4, it follows the positive frame period P2, and the absolute values ​​of the first drive voltage and the second drive voltage are approximately the same.

[0191] For example, the negative frame period P4 can be any period following the positive frame period P2, the absolute value of the first driving voltage can be 8 volts, and the absolute value of the second driving voltage can be 8 volts, but this invention is not limited thereto. In some embodiments, the duration of the negative frame period P4 can be equal to the duration of the positive frame period P2, but this invention is not limited thereto. In some embodiments, the duration of the negative frame period P4 can be greater than the duration of the positive frame period P2, but this invention is not limited thereto.

[0192] Then, during the charging period P3 between the negative frame period P4 and the positive frame period P2, the pixel signal SP1 has a third voltage value that is greater than the second voltage value and less than or equal to the first voltage value.

[0193] For example, during the charging period, P3 can be a negative frame charging period, during which P3 can be used for pixel 113A (e.g., ...). Figure 1B (As shown) for charging, the first voltage value can be 12 volts, the second voltage value can be -4 volts, and the third voltage value can be 0 volts, but this case is not limited to these.

[0194] In one embodiment, during the initial period P1 before the positive frame period P2, the pixel signal has a fourth voltage value that is greater than the third voltage value and less than or equal to the first voltage value.

[0195] For example, the initial period P1 can be the positive frame charging period (+frame charging period), and the initial period P1 can be for pixel 113A (e.g. Figure 1B (As shown) for charging, the first voltage value can be 12 volts, the third voltage value can be 0 volts, and the fourth voltage value can be 8 volts, but this case is not limited to these.

[0196] In one embodiment, during a first period P11, the data signal SD1 has a first data voltage value, the reference signal SC1 has a third reference voltage value, and the initial voltage value of the pixel signal SP1 is increased to a fourth voltage value based on the first data voltage value. The first data voltage value is greater than the third reference voltage value, and the first period P11 is located before the positive frame period P2.

[0197] For example, the first data voltage value of data signal SD1 can be 8 volts, the third reference voltage value of reference signal SC1 can be 0 volts, the initial voltage value of pixel signal SP1 can be -4 volts, and the fourth voltage value of pixel signal SP1 can be 8 volts, but this case is not limited to these.

[0198] In one embodiment, during the second period P12, the data signal SD1 has a second data voltage value, the reference signal SC1 maintains a third reference voltage value, and the pixel signal SP1 maintains a fourth voltage value. The second data voltage value is less than or equal to the first data voltage value, and the second period P12 is located after the first period P11.

[0199] For example, the second data voltage value of data signal SD1 can be 8 volts, the third reference voltage value of reference signal SC1 can be 0 volts, and the fourth voltage value of pixel signal SP1 can be 8 volts, but this case is not limited to these.

[0200] In one embodiment, the range of the first data voltage value of data signal SD1 can be a specific range, and the range of the second data voltage value of data signal SD1 can be a specific range. In one embodiment, the first data voltage value of data signal SD1 is equal to the second data voltage value of data signal SD1. In one embodiment, the first data voltage value of data signal SD1 can be any value, and the second data voltage value of data signal SD1 can be any value, but this invention is not limited thereto.

[0201] For example, the first data voltage value of data signal SD1 can be 4 to 8 volts, and the second data voltage value of data signal SD1 can be 4 to 8 volts, but this case is not limited to this.

[0202] In one embodiment, during the third period P31, the data signal SD1 has a third data voltage value, the reference signal SC1 has a fourth reference voltage value, and the first voltage value of the pixel signal SP1 decreases to a fifth voltage value based on the third data voltage value. The third data voltage value is less than or equal to the second data voltage value, the fourth reference voltage value is greater than the first reference voltage value, and the third period P31 is located after the positive frame period P2.

[0203] For example, the third data voltage value of data signal SD1 can be 0 volts, the fourth reference voltage value of reference signal SC1 can be 8 volts, the first voltage value of pixel signal SP1 can be 12 volts, and the fifth voltage value of pixel signal SP1 can be 0 volts, but this case is not limited to these.

[0204] In one embodiment, during the fourth period P32, the data signal SD1 has a fourth data voltage value, the reference signal SC1 maintains a fourth reference voltage value, and the pixel signal SP1 maintains a fifth voltage value. The fourth data voltage value is less than or equal to the third data voltage value, and the fourth period P32 is located after the third period P31.

[0205] For example, the fourth data voltage value of data signal SD1 can be 0 volts, the fourth reference voltage value of reference signal SC1 can be 8 volts, and the fifth voltage value of pixel signal SP1 can be 0 volts, but this case is not limited to these.

[0206] In one embodiment, the range of the third data voltage value of data signal SD1 can be a specific range, and the range of the fourth data voltage value of data signal SD1 can be a specific range. In one embodiment, the third data voltage value of data signal SD1 is equal to the fourth data voltage value of data signal SD1. In one embodiment, the third data voltage value of data signal SD1 can be any value, and the fourth data voltage value of data signal SD1 can be any value, but this invention is not limited thereto.

[0207] For example, the third data voltage value of data signal SD1 can be 0 to 4 volts, and the fourth data voltage value of data signal SD1 can be 0 to 4 volts, but this case is not limited to this.

[0208] In some embodiments, the gate signal SG1 may have n-level gate signals and n+1-level gate signals, the data signal SD1 may have n-level data signals and n+1-level data signals, the reference signal SC1 may have n-level reference signals and n+1-level reference signals, and the pixel signal SP1 may have n-level pixel signals and n+1-level pixel signals, but this invention is not limited thereto.

[0209] For example, Figure 5AThe n-level signal and the n+1-level signal are similar in operation, with the only difference being the timing and signal size, but this case is not limited to this.

[0210] In some embodiments, the nth level data signal of data signal SD1 is the same as the n+1th level data signal of data signal SD1, but this invention is not limited thereto.

[0211] In some embodiments, Figure 5A The first driving voltage value can correspond to Figure 2A The voltage value of the first driving voltage dv1, Figure 5A The second driving voltage value can correspond to Figure 2A The voltage value of the second driving voltage dv2, but this invention is not limited thereto. In some embodiments, Figure 5A The first driving voltage value can correspond to Figure 2B The voltage value of the first driving voltage dv3, Figure 5A The second driving voltage value can correspond to Figure 2B The voltage value of the second driving voltage dv4, but this case is not limited to it.

[0212] Please refer to the following: Figure 3 and Figure 5A Data line 111B can transmit data signal SD1 to pixel 113B, reference electrode line 112B can transmit reference signal SC1 to pixel 113B, and pixel 113B can have pixel signal SP1, but this is not limited to this.

[0213] In some embodiments, the voltage value of the reference signal SC1 can drop from 4 volts to 0 volts at any time from the start of the positive frame (+frame) until the pixel 113B is fully charged (generally recommended before the gate is turned on). At this time, it can be regarded as the reference electrode line (or common electrode, Com) switching to the positive polarity reference voltage (Vcom+), but this invention is not limited to this.

[0214] In some embodiments, the time point at which the voltage value of the reference signal SC1 rises from 0 volts to 4 volts can be after the pixel 113B has finished charging. At this time, it can be regarded as the reference electrode line (or common electrode, Com) switching to a stable reference voltage (Vcom-stable), but this invention is not limited to this.

[0215] In some embodiments, the voltage value of the reference signal SC1 can rise from 4 volts to 8 volts at any time from the start of the negative frame (-frame) to before the pixel 113B is fully charged (generally recommended before the gate is turned on). At this time, it can be regarded as the reference electrode line (or common electrode, Com) switching to the negative polarity reference voltage (Vcom-), but this invention is not limited to this.

[0216] In some embodiments, the time when the voltage value of the reference signal SC1 drops from 8 volts to 4 volts can be after the pixel 113B has finished charging. At this time, it can be regarded as the reference electrode line (or common electrode, Com) switching to a stable reference voltage (Vcom-stable), but this invention is not limited to this.

[0217] In some embodiments, the voltage value of the pixel signal SP1 rising from -4 volts to 8 volts signifies that after the gate is turned on, pixel 113B is charged by the data signal SD1, but this invention is not limited to this.

[0218] In some embodiments, maintaining the voltage value of pixel signal SP1 at 8 volts means that after the gate is turned off, pixel 113B holds pixel signal SP1, but this invention is not limited to this.

[0219] In some embodiments, the increase in the voltage value of the pixel signal SP1 from 8 volts to 12 volts is the result of the pixel signal SP1 being coupled by the reference voltage after the reference electrode line (or common electrode, Com) switches to a stable reference voltage (Vcom-stable), but this invention is not limited thereto.

[0236] It should be noted that the positive and negative polarities here can represent the relative magnitude of physical quantities. For example, both positive and negative polarities can be positive voltage polarities, and the voltage value of the positive polarity signal can be greater than the voltage value of the negative polarity signal. In this case, both of the voltage values ​​can be positive. The first polarity of the first pixel 63 can come from the first polarity data signal transmitted by the data line 61, but this case is not limited to this.

The first polarity of the first pixel 63D can come from the data signal of the first polarity transmitted by the data line 61C, but this case is not limited to this.

[0249] In one embodiment, data line 61C is coupled to the fourth pixel 63G.

[0257] Then, during the negative frame, the first pixel 63H has a second polarity, the second pixel 63I has a first polarity, the third pixel 63J has a second polarity, and the fourth pixel 63K has a first polarity. The first polarity and the second polarity are different from each other, and the first polarity is related to the reference signal.

The high-order voltage can be used to turn on element U11 (e.g., Figure 1B As shown), the low voltage value can be used to turn off component U11, but this is not the case.

[0288] Please refer to the following: Figures 1A-1B , Figure 7B and Figure 7C In one embodiment, the panel driving device 100 includes a panel 710. The panel 710 includes a data line 74, a plurality of first reference electrode lines 75, 75B, a second reference electrode line 751, and a first pixel 76.

[0289] In one embodiment, the data line 74 is used to transmit the data signal SD3.

[0290] Then, multiple first reference electrode lines 75, 75B are used to transmit the reference signal SC3.

[0291] Next, the second reference electrode line 751 overlaps with and is coupled to each of the plurality of first reference electrode lines 75, 75B.

[0292] Then, the first pixel 76 is used to receive the data signal SD3 and the reference signal SC3.

[0293] Next, the first pixel generates a pixel signal PA based on the data signal SD3 and the reference signal SC3.

[0294] Then, during the positive frame period C2, the difference between the first voltage value of the pixel signal PA and the first reference voltage value of the reference signal SC3 is the first driving voltage value.

[0295] For example, the first voltage value of the pixel signal PA can be 10 volts, the first reference voltage value of the reference signal SC3 can be 2 volts, and the first driving voltage value can be 10-2=8 volts, but this case is not limited to these.

[0296] Next, during the negative frame period C4, the difference between the second voltage value of the pixel signal PA and the second reference voltage value of the reference signal SC3 is the second driving voltage value.

[0297] For example, the second voltage value of the pixel signal PA can be 0 volts, the second reference voltage value of the reference signal SC3 can be 8 volts, and the second driving voltage value can be 8-0=8 volts, but this case is not limited to these.

[0298] In one embodiment, the negative frame period C4 is located after the positive frame period C2, and the absolute value of the first drive voltage value is approximately the same as the absolute value of the second drive voltage value.

[0299] For example, the negative frame period C4 can be located in any period after the positive frame period C2, the absolute value of the first driving voltage value can be 8 volts, the absolute value of the second driving voltage value can be 8 volts, but this case is not limited to this.

[0300] In one embodiment, during the charging period C3 between the negative frame period C4 and the positive frame period C2, the pixel signal PA has a third voltage value that is greater than the second voltage value and less than or equal to the first voltage value.

[0301] For example, the charging period C3 can be located in any period between the negative frame period C4 and the positive frame period C2, and the pixel signal PA can have a third voltage value, which can be 5 volts, but this case is not limited to this.

[0302] In one embodiment, during a first period C11, the data signal SD3 has a first data voltage value, the reference signal SC3 has a first reference voltage value, and the pixel signal PA has an initial voltage value. The first period C11 is located before the positive frame period C2.

[0303] For example, the first data voltage value of data signal SD3 can be 5 volts, the first reference voltage value of reference signal SC3 can be 2 volts, and the initial voltage value of pixel signal PA can be 5 volts, but this case is not limited to these.

[0304] In one embodiment, during the second period C12, the data signal SD3 has a second data voltage value, the reference signal SC3 maintains a first reference voltage value, and the initial voltage value of the pixel signal PA is increased to the first voltage value based on the second data voltage value. The second data voltage value is greater than the first data voltage value, and the second period C12 is located after the first period C11.

[0305] For example, the second data voltage value of data signal SD3 can be 10 volts, the first reference voltage value of reference signal SC3 can be 2 volts, and the first voltage value of pixel signal PA can be 10 volts, but this case is not limited to these.

[0306] In one embodiment, during the third period C31, the data signal SD3 has a first data voltage value, the reference signal SC3 has a second reference voltage value, and the pixel signal PA has a fifth voltage value. The second reference voltage value is greater than the first reference voltage value, and the third period C31 is located after the positive frame period C2.

[0307] For example, the first data voltage value of data signal SD3 is 5 volts, the second reference voltage value of reference signal SC3 can be 8 volts, and the fifth voltage value of pixel signal PA can be 5 volts, but this case is not limited to these.

[0308] In one embodiment, during the fourth period C32, the data signal SD3 has a third data voltage value, the reference signal SC3 maintains a second reference voltage value, and the fifth voltage value of the pixel signal PA decreases to the second voltage value based on the third data voltage value. The third data voltage value is less than or equal to the first data voltage, and the fourth period C32 is located after the third period C31.

[0309] For example, the third data voltage value of data signal SD3 can be 0 volts, the second reference voltage value of reference signal SC3 can be 8 volts, and the second voltage value of pixel signal PA can be 0 volts, but this case is not limited to these.

[0310] In some embodiments, the gate signal SG3 may have n-level gate signals and n+1-level gate signals, the data signal SD3 may have n-level data signals and n+1-level data signals, the reference signal SC3 may have n-level reference signals and n+1-level reference signals, and the pixel signal may have n-level pixel signals PA and n+1-level pixel signals PC, but this invention is not limited thereto.

[0311] For example, Figure 7C The n-level signal and the n+1-level signal are similar in operation. The difference between the two can be in timing and signal size, but this case is not limited to this.

[0315] Figure 8 This is a schematic diagram illustrating the structure of a panel driving device according to an embodiment of this case. Figure 8 As shown, in some embodiments, panel 800 includes multiple data lines 81, 81A, multiple reference electrode lines 82, 82A, 82B, and multiple pixels 83, 83A, 83B, 82C.

[0316] For example, data line 81 can transmit data signals to pixel 83, data line 81A can transmit data signals to pixel 83A, reference electrode line 82A can transmit reference signals of the first polarity to pixels 83 and 83B, reference electrode line 82 can transmit reference signals of the second polarity to pixel 83A, and reference electrode line 82B can transmit reference signals of the second polarity to pixel 83C, but this invention is not limited thereto.

[0317] In some embodiments, during the positive frame interval, Figure 8 The "+" sign can be considered positive, and the "-" sign can be considered negative. In the negative frame region, Figure 3 The polarities of "+" and "-" in Chinese are reversed, but this case is not limited to this.

[0319] In some embodiments, Figure 8 The design of the 800 panel can provide Figure 8 This is another design of the panel 300, but this case is not limited to it.

[0320] Figure 9A This is a timing diagram illustrating multiple signals of a panel driving device according to an embodiment of this case. Figure 9A As shown, in some embodiments, Figure 9A It has a gate signal SG4, a data signal SD4, a reference signal SC4, and a pixel signal SP4.

[0321] For example, Figure 9A The gate signal SG4 can correspond to Figure 1B The gate signal SG, Figure 9A The data signal SD4 can correspond to Figure 1B Data signal SD, Figure 9A The reference signal SC4 can correspond to Figure 1B The reference signal SC, Figure 9A The pixel signal SP4 can correspond to Figure 1B The pixel signal measured by the middle node U13, but this case is not limited to this.

[0322] In some embodiments, the gate signal SG4 has a high-order voltage value and a low-order voltage value.

[0323] For example, the high-order voltage value of gate signal SG4 can be 30 volts, and the low-order voltage value of gate signal SG1 can be 0 volts. The high-order voltage value can be used to turn on element U11 (e.g., Figure 1B As shown), the low voltage value can be used to turn off component U11, but this is not the case.

[0324] In some embodiments, Figure 9A The operation is similar to Figure 5A The operation is based on a concise instruction manual and will not be described in detail here. It should be noted that... Figure 9A The timing and / or voltage values ​​of the data signal SD4, reference signal SC4 and / or pixel signal SP4 can be adjusted according to user requirements, but this application is not limited to this.

[0325] Please refer to the following: Figure 8 and Figure 9A Data line 81 can transmit data signal SD4 to pixel 83, reference electrode line 82A can transmit reference signal SC4 to pixels 83 and 83B, and pixel 83 can have pixel signal SP4, but this is not a limitation in this case.

[0326] In some embodiments, the voltage value of the reference signal SC4 can drop from 4 volts to 0 volts at any time from the start of the positive frame (+frame) until the pixel 83 is fully charged (generally recommended before the gate is turned on). At this time, it can be regarded as the reference electrode line (or common electrode, Com) switching to the positive polarity reference voltage (Vcom+), but this invention is not limited to this.

[0327] In some embodiments, the time point at which the voltage value of the reference signal SC4 rises from 0 volts to 4 volts can be after the pixel 83B has finished charging. At this time, it can be regarded as the reference electrode line (or common electrode, Com) switching to a stable reference voltage (Vcom-stable), but this invention is not limited to this.

[0328] In some embodiments, the voltage value of the reference signal SC4 can rise from 4 volts to 8 volts at any time from the start of the negative frame (-frame) to before the pixel 83 is fully charged (generally recommended before the gate is turned on). At this time, it can be regarded as the reference electrode line (or common electrode, Com) switching to the negative polarity reference voltage (Vcom-), but this invention is not limited to this.

[0329] In some embodiments, the time when the voltage value of the reference signal SC4 drops from 8 volts to 4 volts can be after the pixel 83B has finished charging. At this time, it can be regarded as the reference electrode line (or common electrode, Com) switching to a stable reference voltage (Vcom-stable), but this invention is not limited to this.

[0330] In some embodiments, the voltage value of the pixel signal SP4 rising from -4 volts to 8 volts signifies that after the gate is turned on, pixel 83 is charged by the data signal SD4, but this invention is not limited to this.

[0331] In some embodiments, maintaining the voltage value of pixel signal SP4 at 8 volts means that after the gate is turned off, pixel 83 holds pixel signal SP4, but this invention is not limited to this.

[0332] In some embodiments, the increase in the voltage value of the pixel signal SP4 from 8 volts to 12 volts is the result of the pixel signal SP4 being coupled by the reference voltage after the reference electrode line (or common electrode, Com) switches to a stable reference voltage (Vcom-stable), but this application is not limited to this.
