[0060] As shown in FIG1 , the present application provides a display panel, which includes:

[0061] A plurality of pixel units 100, wherein the plurality of pixel units 100 are arranged in an array on the display panel;

[0062] The source driver module 200 includes a data driver chip 210 and a plurality of multiplexing circuits. The data driver chip 210 includes a plurality of output ports, each of which is connected to a plurality of the multiplexing circuits and outputs a plurality of pre-charge signals and data signals to the data lines under the control of the plurality of the multiplexing circuits.

[0063] The two data lines control a column of pixel units 100 .

[0064] This application uses a multiplexing circuit to control the data driver chip to output pre-charge signals and data signals to the data line, solving the problem in the double dataline multi-MUX architecture where the charging order of multiple MUXs corresponding to the same color is different, resulting in different compensation times and causing brightness differences.

[0065] The following will describe in detail the various embodiments of the present application that are consistent with the above-mentioned creative concepts.

[0066] As shown in Figures 1 to 3 , the present application provides a display panel that includes a display area 1000 and a non-display area 2000 disposed around the display area 1000 .

[0067] A plurality of pixel units 100 are provided in the display area 1000. The plurality of pixel units 100 are arranged in an array in the display area 1000. For example, in a rectangular display panel, the plurality of pixel units 100 can be arranged in a rectangular array in the display panel. The plurality of pixel units 100 include a first pixel unit having a first color, a second pixel unit having a second color, and a third pixel unit having a third color, and the first color, the second color, and the third color are different. Optionally, the first color can be one of red, green, or blue, the second color can be another of red, green, or blue, and the third color can be the last of red, green, or blue. This application is described by taking the first color being blue, the second color being green, and the third color being red as an example.

[0068] The non-display area 2000 is provided with a source driver module 200 and a gate driver module 300. The source driver module 200 transmits a data signal to the pixel unit 100 via the data line to drive the pixel unit 100 to emit light. The gate driver module 300 transmits a gate drive signal to the pixel unit 100 via the gate line to control whether the data line transmits a data signal to the pixel unit 100. Optionally, the source driver module 200 can be arranged at the bottom relative to the display panel, and the gate driver module 300 can be arranged at the side relative to the display panel. A plurality of gate lines are uniformly arranged on the display panel along the column direction, each gate line extends along the row direction of the display panel, and one gate line controls a row of pixel units 100. A plurality of data lines are arranged on the display panel along the row direction, each data line extends along the column direction of the display panel, and two data lines jointly control a column of pixel units 100.

[0069] The source driver module 200 includes a data driver chip 210 and a plurality of multiplexing circuits. The data driver chip 210 includes a plurality of output ports, each of which is connected to a plurality of multiplexing circuits and outputs a plurality of pre-charge signals and data signals to the data lines under the control of the plurality of multiplexing circuits. For example, the data driver chip 210 includes fifty output ports (S1, S2, S3 ... S49, S50), each of which is connected to four multiplexing circuits (MUX1, MUX2, MUX3, MUX4). Take the connection of S1 to four multiplexing circuits (MUX1, MUX2, MUX3, MUX4) as an example. S1 generates four pre-charge signals and four data signals under the control of the four multiplexing circuits, and outputs the four pre-charge signals to the four data lines (D1, D2, D3, D4) respectively, and outputs the four data signals to the four data lines (D1, D2, D3, D4) respectively. Similarly, fifty output terminals (S1, S2, S3, ..., S49, S50) can generate two hundred pre-charge signals and two hundred data signals. If two data lines drive one column of pixel units 100, then one hundred columns of pixel units 100 can be driven by two hundred data lines.

[0070] The gate driver module 300 includes a plurality of gate driver units (GOAs) arranged along the column direction of the display panel. The multiple GOA units arranged along the column direction can be cascaded or non-cascaded. Each GOA unit is connected to a row of gate lines. The GOA unit generates a gate drive signal and transmits the gate drive signal to a row of pixel units 100 corresponding to the gate line through the gate line.

[0071] The source driver module 200 outputs a precharge signal before the active level section of the corresponding gate drive signal, and outputs a data signal during the active level section of the gate drive signal. That is, the multiplexing circuit controls the data driver chip 210 to output the precharge signal before the active level section of the gate drive signal. The multiplexing circuit controls the data driver chip 210 to output the data signal during the active level section of the gate drive signal.

[0072] As shown in Figures 1 to 3, in an optional embodiment, the pixel units in odd rows are arranged in a periodic sequence of the first pixel unit, the second pixel unit, the third pixel unit, and the second pixel unit; the pixel units in even rows are arranged in a periodic sequence of the third pixel unit, the second pixel unit, the first pixel unit, and the second pixel unit.

[0073] That is, the pixel units in odd rows are arranged in a periodic sequence of blue pixel units, green pixel units, red pixel units, and green pixel units, and the pixel units in even rows are arranged in a periodic sequence of red pixel units, green pixel units, blue pixel units, and green pixel units. G1, G2, ..., Ga control the first row, second row, ..., a-th row of pixel units 100, respectively, where a is an integer greater than 1. D1 and D2 control the first column, D3 and D4 control the second column, ..., D2b-1 and D2b control the b-th column of pixel units 100, where b is an integer greater than 1. The data lines of odd columns are connected to the odd-numbered pixel units 100 in the controlled columns, and the data lines of even columns are connected to the even-numbered pixel units 100 in the controlled columns.

[0074] Two adjacent rows of gate lines are one group in the gate drive module 300, and the gate drive signals of the same group of gate lines are in phase, and the gate drive signal of the next group of gate lines lags behind one phase than the gate drive signal of this group of gate lines. For example, G1 and G2 are one group, and G3 and G4 are one group... G2a-1 and G2a are the same group, and a is an integer greater than 1. The gate drive signals of the same group of gate lines are in phase, and the gate drive signal of the next group of gate lines lags behind one phase than the gate drive signal of this group of gate lines. That is, the gate drive signal of GOA2a-1 and GOA2a outputs is in phase, and the gate drive signal of G2a-1 and G2a outputs lags behind one phase of the gate drive signal of G2a-3 and G2a-2 outputs, and a is an integer greater than 1.

[0075] Each output port (S1, S2 ...) of gate driver chip 210 in source driver module 200 is all connected with four multiplexing circuits (MUX1, MUX2, MUX3, MUX4), produces four pre-charge signals and four data signals.Four pre-charge signals are one group, and four data signals are one group, and four data lines are one group.One group of data lines receives one group of pre-charge signals and one group of data signals.One group of pre-charge signals is output before the effective level section of the gate drive signal of corresponding one group of gate lines, and one group of pre-charge signals is output in the effective level section of the gate drive signal of corresponding one group of gate lines.For example, S1 is connected with MUX1, MUX2, MUX3, MUX4, produces four pre-charge signals and four data signals under the control of MUX1, MUX2, MUX3, MUX4, and four pre-charge signals are output to D1, D2, D3, D4 respectively before the effective level section of gate drive signal, and four data signals are output to D1, D2, D3, D4 respectively in the effective level section of gate drive signal. Optionally, the four precharge signals output to D1, D2, D3, and D4 are phase-synchronized, and the four data signals output to D1, D2, D3, and D4 are phase-delayed in the order of D3, D4, D2, and D1.

[0076] Specifically, S1 is connected to MUX1, MUX2, MUX3, and MUX4, and generates four pre-charge signals and four data signals under the control of MUX1, MUX2, MUX3, and MUX4. The four pre-charge signals are output to D1, D2, D3, and D4 respectively before the effective level segments of G1 and G2, and the four data signals are output to D1, D2, D3, and D4 respectively during the effective level segments of G1 and G2. Optionally, the four pre-charge signals output to D1, D2, D3, and D4 are phase-synchronized. The four data signals output to D1, D2, D3, and D4 lag in phase in the order of D3, D4, D2, and D1.

[0077] S2 is connected to MUX1, MUX2, MUX3, and MUX4, and generates four pre-charge signals and four data signals under the control of MUX1, MUX2, MUX3, and MUX4.

Optionally, the four pre-charge signals output to D5, D6, D7, and D8 are phase-synchronized. The four data signals output to D5, D6, D7, and D8 lag in phase in the order of D7, D8, D5, and D6.

[0078] S2n-1 is connected to MUX1, MUX2, MUX3, and MUX4, and generates four pre-charge signals and four data signals under the control of MUX1, MUX2, MUX3, and MUX4. The four pre-charge signals are output to D8n-7, D8n-6, D8n-5, and D8n-4 respectively before the effective level section of G1 and G2, and the four data signals are output to D8n-7, D8n-6, D8n-5, and D8n-4 respectively during the effective level section of G1 and G2. Optionally, the four pre-charge signals output to D8n-7, D8n-6, D8n-5, and D8n-4 are phase-synchronized. The four data signals output to D8n-7, D8n-6, D8n-5, and D8n-4 lag in phase in the order of D8n-5, D8n-4, D8n-6, and D8n-7. n is an integer greater than 1.

[0079] S2n is connected to MUX1, MUX2, MUX3, and MUX4, and generates four pre-charge signals and four data signals under the control of MUX1, MUX2, MUX3, and MUX4. The four pre-charge signals are output to D8n-3, D8n-2, D8n-1, and D8n respectively before the effective level section of G1 and G2, and the four data signals are output to D8n-3, D8n-2, D8n-1, and D8n respectively during the effective level section of G1 and G2. Optionally, the four pre-charge signals output to D8n-3, D8n-2, D8n-1, and D8n are phase-synchronized. The four data signals output to D8n-3, D8n-2, D8n-1, and D8n lag in phase in the order of D8n-1, D8n, D8n-3, and D8n-2. n is an integer greater than 1.

[0080] In this way, the scanning and emitting of the first and second rows of pixel units 100 are completed. Similarly, the pixel units 100 in other rows are scanned and emitted step by step according to the phase sequence of the GOA signal of each row.

[0081] As shown in Figures 1, 4, and 5, in an optional embodiment, the pixel cells in odd rows are arranged in a sequential periodic arrangement of a first pixel cell, a second pixel cell, and a third pixel cell. The pixel cells in even rows are arranged in a sequential periodic arrangement of a third pixel cell, a second pixel cell, and a first pixel cell. That is, the pixel cells in odd rows are arranged in a sequential periodic arrangement of a blue pixel cell, a green pixel cell, and a red pixel cell, while the pixel cells in even rows are arranged in a sequential periodic arrangement of a red pixel cell, a green pixel cell, and a blue pixel cell. G1, G2, ..., Ga control the first row, the second row, ..., the a-th row of pixel cells 100, respectively, where a is an integer greater than 1. D1 and D2 control the first column, D3 and D4 control the second column, ..., D2b-1 and D2b control the b-th column of pixel cells 100, where b is an integer greater than 1. The data lines of the odd columns are connected to the odd-row pixel cells 100 in the controlled columns, and the data lines of the even columns are connected to the even-row pixel cells 100 in the controlled columns.

[0082] Two adjacent rows of gate lines are one group in the gate drive module 300, and the gate drive signals of the same group of gate lines are in phase, and the gate drive signal of the next group of gate lines lags behind one phase than the gate drive signal of this group of gate lines. For example, G1 and G2 are one group, and G3 and G4 are one group... G2a-1 and G2a are the same group, and a is an integer greater than 1. The gate drive signals of the same group of gate lines are in phase, and the gate drive signal of the next group of gate lines lags behind one phase than the gate drive signal of this group of gate lines. That is, the gate drive signal of GOA2a-1 and GOA2a outputs is in phase, and the gate drive signal of G2a-1 and G2a outputs lags behind one phase of the gate drive signal of G2a-3 and G2a-2 outputs, and a is an integer greater than 1.

[0083] Each output port (S1, S2 ...) of the gate driver chip 210 in the source driver module 200 is connected to three multiplexing circuits (MUX1, MUX2, MUX3) to generate three pre-charge signals and three data signals. Three pre-charge signals form a group, three data signals form a group, and three data lines form a group. A group of data lines receives a group of pre-charge signals and a group of data signals.
