AI Technical Summary
Due to limited layout space, designing too many data lines can cause crosstalk between closely spaced data lines, leading to crosstalk-related display problems.
Each column of driving circuits corresponds to two data lines. Odd-numbered sub-pixel driving circuits are coupled to the first data line, and even-numbered sub-pixel driving circuits are coupled to the second data line. The distance between the two data lines in the first data line group is less than the distance between the two data lines in the second data line group. The writing time consistency of the data lines is controlled by the gating sub-unit to avoid crosstalk.
This effectively reduces crosstalk between closely spaced data lines, ensuring that each sub-pixel driving circuit can fully write data signals, thus improving display defects caused by crosstalk.

[0097] More specifically, the above embodiment is based on MUX1:4 (i.e. one data signal input end corresponds to four data lines), i.e. column MUX1:2 (i.e. one column driving circuit column corresponds to two data lines) + row MUX1:2 (i.e. an odd-numbered row driving circuit row corresponds to a first data line, and an even-numbered row driving circuit row corresponds to a second data line) combined with shift register unit odd and even row driving, which can improve sub-pixel threshold voltage compensation time and improve display uniformity. However, due to MUX1:4, the number of data lines to be set is doubled, and in spatial arrangement, the distance between adjacent data lines will necessarily decrease, i.e. the parasitic capacitance between adjacent data lines will increase. At the same time, the crosstalk between data lines will increase, which is easy to form crosstalk type display defects.
[0098] As shown in Figure 15 The first selection signal transmitted by the first gate control line MUX1, the second selection signal transmitted by the second gate control line MUX2, the third selection signal transmitted by the third gate control line MUX3 and the fourth selection signal transmitted by the fourth gate control line MUX4 are in turn at the active level (such as low level), and when the selection signal is at the active level, the corresponding gate transistor is turned on, and the data signal provided by the data signal input end is written into the corresponding data line.
[0099] As shown in the time period boxed by the dashed box in Figure 15 corresponding to the low potential of the scanning signal GateP[2n-1], at this time the data writing transistor T4 in the 2n-1 row sub-pixel is opened, and the data line controlled by the first gate control line MUX1 and the second gate control line MUX2 writes the data signal to the gate of the driving transistor T3 through the data writing transistor T4 and the compensation transistor T2 (the data signal on this data line is pre-stored or written in the current period), that is, the data line controlled by the first gate control line MUX1 and the second gate control line MUX2 writes the data signal to the N1 node, and in this time period, the data line corresponding to the 2n row sub-pixel is controlled by the third gate control line MUX3 and the fourth gate control line MUX4 to write data signal to the data line and store in the data line, so as to realize writing the corresponding sub-pixel driving circuit when the scanning signal GateP[2n] is at low level; if the data line controlled by the third gate control line MUX3 and the fourth gate control line MUX4 has large parasitic capacitance with the data line controlled by the first gate control line MUX1 and the second gate control line MUX2, then the data line controlled by the third gate control line MUX3 and the fourth gate control line MUX4 will directly pull the data voltage of the data line controlled by the first gate control line MUX1 and the second gate control line MUX2 when the data voltage jumps, and since the scanning signal GateP[2n-1] is at low level at this time, the pulled data voltage will be directly written into the corresponding sub-pixel driving circuit, resulting in signal writing abnormality of the sub-pixel driving circuit, which is manifested as poor crosstalk.
[0100] The display panel provided by the above embodiment adopts DDL combined with MUX1:4 driving design, and the two data lines with large parasitic capacitance in the same first data line group are adjusted to the data line corresponding to the same row of sub-pixels through MUX transformation, so that in the whole display panel, the two data lines close to each other are only the second data line DA2 controlled by MUX3 and MUX4, or the first data line DA1 controlled by MUX1 and MUX2, greatly reducing the crosstalk problem between the data lines in the same first data line group.
[0101] AsFigures 2 to 14 In some embodiments, the sub-pixel driving circuit further comprises a data writing transistor T4, a first reset transistor T1, a first conductive connection 31 and a second conductive connection 32.
[0102] In at least part of the sub-pixels, a first electrode of the data writing transistor T4 is coupled with a corresponding data line through the first conductive connection 31, and a second electrode of the data writing transistor T4 is coupled with a first electrode of the driving transistor T3; a second electrode of the first reset transistor T1 is coupled with a gate electrode of the driving transistor through the second conductive connection 32.
[0103] In at least part of the sub-pixels, a normal projection of the second conductive connection 32 on the substrate substrate is located between a normal projection of an active layer of the data writing transistor T4 on the substrate substrate and a normal projection of a data line coupled with the data writing transistor T4 on the substrate substrate; in the at least part of the sub-pixels, the first conductive connection 31 comprises a first connection portion 311 and a second connection portion 312 coupled with each other, an extension direction of the first connection portion 311 intersects with an extension direction of the second connection portion 312, the first connection portion 311 is coupled with the corresponding data line, and the second connection portion 312 is coupled with the first electrode of the data writing transistor T4.
[0104] For example, the first conductive connection 31 and the second conductive connection 32 are provided in the same layer and with the same material, but are not limited thereto.
[0105] For example, in at least part of the sub-pixels, the data writing transistor T4 included in the sub-pixel is close to one side of the sub-pixel driving circuit included in the sub-pixel, and a data line coupled with the data writing transistor T4 included in the sub-pixel is close to the other side of the sub-pixel driving circuit, i.e., the data writing transistor T4 included in the sub-pixel and the data line coupled with the data writing transistor T4 are located on opposite sides of the sub-pixel driving circuit.
[0106] For example, the first conductive connection 31 comprises a first connection portion 311 and a second connection portion 312 coupled with each other, and the first connection portion 311 and the second connection portion 312 are formed in an integrated structure.
[0107] The above arrangement allows the data writing transistor T4 and the data line coupled therewith to be connected through the first conductive connection 31 in the at least part of the sub-pixels.
[0108] For example, the data writing transistor T4 is located on one side of the sub-pixel driving circuit, and the data line coupled with the data writing transistor T4 is located on the other side of the sub-pixel driving circuit. Figure 8 , Figure 13 and Figure 14As shown, in some embodiments, the display panel further includes a power line VDD, and the orthographic projection of the first conductive connection portion 31 on the substrate at least partially overlaps with the orthographic projection of the power line VDD on the substrate.
[0109] The above configuration enables the power line VDD to shield the signal transmitted by the first conductive connection 31 from interference from surrounding signals, thus ensuring the stability of the signal transmitted by the first conductive connection 31.
[0110] In some embodiments, the plurality of sub-pixels includes red sub-pixels, green sub-pixels, and blue sub-pixels; in the driving circuit group Z2, the first column of driving circuits includes sub-pixel driving circuits for alternating red sub-pixels and sub-pixel driving circuits for alternating blue sub-pixels, and the second column of driving circuits includes sub-pixel driving circuits for a plurality of green sub-pixels arranged in sequence.
[0111] For example, the first column of driving circuits includes sub-pixel driving circuits for red sub-pixels and blue sub-pixels arranged alternately along the second direction, and the second column of driving circuits includes sub-pixel driving circuits for a plurality of green sub-pixels arranged sequentially along the second direction.
[0112] For example, in two adjacent sets of driving circuit groups Z2, the first column of driving circuits in one set of driving circuit groups Z2 includes alternating sub-pixel driving circuits for red sub-pixels and sub-pixel driving circuits for blue sub-pixels, and the first column of driving circuits in the other set of driving circuit groups Z2 includes alternating sub-pixel driving circuits for blue sub-pixels and sub-pixel driving circuits for red sub-pixels.
[0113] By arranging subpixels in the above manner, each data line can be coupled to a subpixel of only one color. This means that the range of data signal transitions on each data line is small. Thus, even if one data line in the first data line group Z11 experiences a data signal transition, the crosstalk to the other data line is also small. Similarly, if one data line in the second data line group Z12 experiences a data signal transition, the crosstalk to the other data line is also small.
[0114] like Figure 13 As shown, in some embodiments, the display panel further includes multiple power lines VDD, and the orthographic projection of the power line VDD corresponding to the driving circuit column on the substrate is located between the orthographic projections of the two data lines corresponding to the driving circuit column on the substrate.
[0115] For example, the power line VDD is used to transmit a power signal with a stable potential.
[0116] For example, the orthographic projection of the power line VDD corresponding to the drive circuit column on the substrate is located between the orthographic projection of the first data line DA1 and the second data line DA2 corresponding to the drive circuit column on the substrate.
[0117] For example, the power line VDD corresponding to the driving circuit column is located between the red data line used to transmit the data signal corresponding to the red sub-pixel and the blue data line used to transmit the data signal corresponding to the blue sub-pixel; or, the power line VDD corresponding to the driving circuit column is located between the green data line used to transmit the data signal corresponding to the green sub-pixel and the green data line used to transmit the data signal corresponding to the green sub-pixel.
[0118] The above configuration allows the power line VDD to effectively shield the crosstalk between the two data lines corresponding to the drive circuit column.
[0119] In some embodiments, the display panel further includes a shielding line whose orthogonal projection on the substrate is located between the orthogonal projections of the two data lines in the first data line group on the substrate.
[0120] For example, the shielded wire is used to transmit an initialization signal, that is, the shielded wire is multiplexed as an initialization signal line; or, the shielded wire is used to transmit a power signal, that is, the shielded wire is multiplexed as a power line VDD.
[0121] It should be noted that the shielding line can be set when the product PPI is relatively small, that is, the pixel size is relatively large and there is sufficient layout space.
[0122] The above configuration enables the shielding cable to effectively shield crosstalk between the two data lines in the first data line group.
[0123] like Figure 13 As shown, in some embodiments, the two data lines in the same group of second data lines Z12 include a first data line DA1 and a second data line DA2.
[0124] For example, the display panel also includes a plurality of first signal lines 40, with one of the first signal lines 40 between two data lines in the second data line group Z12.
[0125] Exemplarily, the first signal line 40 includes an FIP lead, but is not limited thereto. It should be noted that, in order to meet the demand of narrowing the lower frame of the display panel, the display panel can be designed by FIP, that is, the data lines of the left frame and the right frame of the display panel are connected with the FIP lead, the lead is extended to the middle region of the display panel, and then extended to the lower frame region from the middle region, so as to narrow the width of the lower frame of the display panel.
[0126] Exemplarily, the first signal line 40 includes a power supply line VDD or an initialization signal line, but is not limited thereto.
[0127] The above-mentioned arrangement that the two data lines in the second data line group Z12 are provided with the first signal line 40 between the two data lines, so that the first signal line 40 can effectively shield the crosstalk between the two data lines in the second data line group Z12.
[0128] As shown in FIG. 1, Figure 21 In some embodiments, the plurality of sub-pixels are divided into a plurality of driving circuit rows, and in the same driving circuit row, the sub-pixel driving circuits included in adjacent two sub-pixels are mirror-symmetrical.
[0129] It should be noted that, Figure 21 F in FIG. 2 represents a sub-pixel driving circuit, and is not a layout of the sub-pixel driving circuit in the shape of F. It can be seen that in the same driving circuit row, the sub-pixel driving circuits included in adjacent two sub-pixels are mirror-symmetrical, and in the same driving circuit column, the sub-pixel driving circuits have the same layout and are not mirror-processed.
[0130] Exemplarily, in the same driving circuit row, the odd-numbered sub-pixel driving circuits and the even-numbered sub-pixel driving circuits are mirror-symmetrical.
[0131] Exemplarily, the sub-pixel driving circuits included in adjacent two sub-pixels are mirror-symmetrical, and the axis of symmetry of the mirror symmetry is located between the sub-pixel driving circuits included in the adjacent two sub-pixels and extends along the second direction.
[0132] The above-mentioned arrangement is beneficial to the display panel to achieve a higher PPI, and the FIP horizontal and vertical wiring layout is more optimal and has better symmetry, and the anode layer in the display panel has better flatness.

[0134] The first type of data line comprises a first data portion 61, a first type of cross-region data portion 62 and a second data portion 63 coupled in sequence, the first data portion 61 and the second data portion 63 are located on opposite sides of the hole region 50, and the first data portion 61, the first type of cross-region data portion 62 and the second data portion 63 are all located in the pixel region 52.

[0136] Illustratively, the display panel comprises a hole region 50, an isolation region 51 and a pixel region 52, the isolation region 51 is located between the hole region 50 and the pixel region 52, the isolation region 51 surrounds the hole region 50, and the pixel region 52 surrounds the isolation region 51.
[0137] Illustratively, the plurality of data lines comprises a plurality of cross-hole region data lines, the cross-hole region data line refers to the data line that will pass through the hole region 50 if the data line is extended in the second direction, and in the actual layout, the data line will bypass the hole region 50, that is, will not pass through the hole region 50.
[0138] Illustratively, the first type of data line comprises a first data portion 61, a first type of cross-region data portion 62 and a second data portion 63 coupled in sequence, the first data portion 61 and the second data portion 63 are located on opposite sides of the hole region 50 in the second direction.
[0139] Illustratively, the first data portion 61 and the second data portion 63 both extend in the second direction, and the first type of cross-region data portion 62 comprises a portion extending in the first direction and a portion extending in the second direction. When the first type of data line adopts the above structure, it is formed in a HIP winding mode.
[0140] Illustratively, the second type of data line comprises a third data portion 71, a second type of cross-region data portion 72 and a fourth data portion 73 coupled in sequence, the third data portion 71 and the fourth data portion 73 are located on opposite sides of the hole region 50 in the second direction.
[0141] Exemplarily, the third data portion 71 and the fourth data portion 73 both extend along the second direction, and the second type of cross-zone data portion 72 extends along the edge of the hole zone 50. When the first type of data line adopts the above structure, that is, is formed in a Fanout winding mode.
[0142] Exemplarily, as shown in Figure 18 and Figure 20 Exemplarily, the plurality of second type of data lines are divided into a first part of second type of data lines and a second part of second type of data lines, and the plurality of first type of data lines (located in the B1 region) are located between the first part of second type of data lines (located in the B2 region) and the second part of second type of data lines (located in the B3 region).

For example, the first type of data line is coupled with a corresponding green sub-pixel, and the second type of data line is coupled with a corresponding red sub-pixel and / or blue sub-pixel.
[0144] It is worth noting that, by adopting the design that each column of driving circuit columns corresponds to two data lines (that is, the DDL design), the number of data lines in the display panel will be doubled, so that the number of data lines that need to be wound in the hole zone 50 will also be doubled. If only the Fanout winding mode is adopted, the doubled number of winding in the hole zone 50 will lead to an increase in the wiring space of the isolation zone 51, which will directly lead to an increase in the frame of the hole zone 50.
[0145] The above setting mode adopts a combination of the HIP winding mode and the Fanout winding mode, which can greatly narrow the frame width of the hole zone 50 under the DDL design. More specifically, the display panel provided by the embodiment of the present application can reduce the Fanout winding by 152, and the frame width of the hole zone 50 can be reduced by about 190 microns.

[0148] The second conductive connection part 32 is coupled with the second electrode of the compensation transistor T2 and the second electrode of the first reset transistor T1 respectively through the fifth via Via5, and coupled with the gate T3-g of the driving transistor T3 through the seventh via Via7.

In this way, the odd-numbered and even-numbered sub-pixel driving circuits in a column of driving circuit columns are provided with data signals from different data lines, the time for the data lines to write data signals to the corresponding sub-pixel driving circuits is extended, the data signals can be fully written to each sub-pixel driving circuit, and the display defects caused by insufficient writing of data signals are avoided.
[0158] In the display panel provided by the above embodiment, the distance between two data lines in the first data line group Z11 is less than the distance between two data lines in the second data line group Z12, and the two data lines in the same group of the first data line group Z11 are both the first data line DA1 or both the second data line DA2. When scanning an odd-numbered row of sub-pixels or an even-numbered row of sub-pixels in the display panel, the two data lines close to each other in the first data line group Z11 can write data signals to the sub-pixel driving circuits in the same odd-numbered row or write data signals to the sub-pixels in the same even-numbered row. In this way, the two data lines close to each other in the first data line group Z11 can be controlled by the gate sub-unit, the time for writing data signals is close, that is, the time for the two data lines to write data signals to the sub-pixel driving circuits is the same, thereby shortening the time difference for the two data lines close to each other in the first data line group Z11 to write data signals and reducing the risk that one data line is in a floating state and is disturbed by another data line after completing data writing. Therefore, the display panel provided by the above embodiment effectively reduces the crosstalk between the two data lines close to each other and improves the crosstalk display defects caused by the crosstalk between the data lines.
