Abstract
Description
Technical Field
[0001] The present application relates to the field of display technology, and in particular to a display panel, a display device and a driving method thereof. Background Art
[0002] With the continuous development of display technology, ultra-high resolution display has become a possibility. At present, the display with a pixel density of up to 3000 (PPI) is no longer a fantasy. However, due to factors such as system capacity and graphics card processing speed, ultra-high resolution display cannot be popularized. Therefore, a partition-driven intelligent display mode is proposed, which displays the areas that the human eye focuses on normally, and reduces the resolution and refresh rate of the remaining areas, which can not only deal with the problem of insufficient system resources, but also meet the demand for low power consumption. However, the display products in the prior art can only realize the function of horizontal partition driving, and cannot realize vertical partition. Summary of the invention

[0174] The control electrode of the second transistor T2 is electrically connected to a control signal line 8 , the first electrode of the second transistor T2 is electrically connected to the fixed potential line 9 , and the second electrode of the second transistor T2 is electrically connected to the scanning line 2 .
[0175] In a specific implementation, for a plurality of control circuits corresponding to a control area, under the control of a control signal inputted by a control signal line, when the first transistor is turned on and the second transistor is turned off, a signal inputted by a scanning signal input line is transmitted to the scanning line through the first transistor to refresh the pixel island of the control area. Under the control of a control signal inputted by a control signal line, when the second transistor is turned on and the first transistor is turned off, a low-level signal inputted by a fixed potential line is transmitted to the scanning line through the second transistor, i.e., the pixel island of the control area does not need to be refreshed.
[0176] In some embodiments, the second electrode of the first transistor T1 and the second electrode of the second transistor T1 in one control circuit are electrically connected to the same sub-scan line.
[0177] In some embodiments, Figure 1 As shown, the control electrode of the first transistor T1 and the control electrode of the second transistor T1 are electrically connected to the same control signal line 8;
[0178] The first transistor is an N-type transistor, and the second transistor is a P-type transistor; or, the first transistor is a P-type transistor, and the second transistor is an N-type transistor.
[0179] In some embodiments, Figure 2 , Figure 3 As shown, the control electrode of the first transistor T1 and the control electrode of the second transistor T2 are electrically connected to different control signal lines 8 .
[0180] In some embodiments, Figure 2 , Figure 3 As shown, the plurality of control signal lines 8 include: a plurality of first control signal lines 12 and a plurality of second control signal lines 13;
[0181] The control electrode of the first transistor T1 is electrically connected to the first control signal line 12 , and the control electrode of the second transistor T2 is electrically connected to the second control signal line 13 .
[0182] In a specific implementation, when the control electrode of the first transistor and the control electrode of the second transistor are electrically connected to different control signal lines, the first transistor can be an N-type transistor or a P-type transistor, and the second transistor can be an N-type transistor or a P-type transistor.
[0183] In some embodiments, Figure 1 , Figure 2 As shown, the control circuit 10 is located between two adjacent sub-pixels 4 in the first direction X;
[0184] The plurality of fixed potential lines 9 extend along the first direction X and are arranged along the second direction Y.
[0185] That is Figure 1 , Figure 2 As shown, the control circuit 10 is located between two adjacent columns of sub-pixels 4 .
[0186] Next, the structure of the display panel is described by taking the example that the control circuit is located between two adjacent columns of sub-pixels.
[0187] In some embodiments, Figure 5 As shown, the display panel specifically includes:
[0188] The first conductive layer 14 includes a scan line 2, a scan signal input line 7, a fixed potential line 9, a control electrode G1 of the first transistor T1, and a control electrode G2 of the second transistor T2;
[0189] The second conductive layer 15 is located on the side of the first conductive layer 14 away from the first substrate, and includes the data line 3 and the control signal line 8;
[0190] The third conductive layer 17 is located on a side of the second conductive layer 15 away from the first conductive layer 14 , and includes a first electrode S1 and a second electrode D2 of the first transistor T1 , and a first electrode S2 and a second electrode D2 of the second transistor T2 .
[0191] and Figure 5 The corresponding patterns of the first conductive layer 14, the second conductive layer 15, and the third conductive layer 17 are as follows: Figure 8 , Fig.10 , Fig.12 shown.
[0192] In some embodiments, Figure 5 As shown, in each control circuit, the first transistors T1 and the second transistors T2 are arranged in two rows along a first direction.
[0193] In some embodiments, Figure 5 , Figure 8 As shown, in each control circuit, the orthographic projection of the control electrode G1 of the first transistor T1 on a plane perpendicular to the first direction and the orthographic projection of the control electrode G2 of the second transistor T2 on a plane perpendicular to the first direction do not overlap each other. That is, the control electrode G1 of the first transistor T1 and the control electrode G2 of the second transistor T2 are not arranged along a straight line parallel to the first direction, so that even if the control electrode G1 of the first transistor T1 and the control electrode G2 of the second transistor T2 have an overlapping area in the second direction, the control electrode G1 of the first transistor T1 and the control electrode G2 of the second transistor T2 will not have a short circuit problem. Accordingly, the total width of the first transistor T1 and the second transistor T2 in the first direction can be reduced, thereby minimizing the impact of the setting of the control circuit on the aperture ratio.
[0194] In some embodiments, Figure 5 , Fig.10 As shown, in the second direction, in each first transistor T1, the first electrode S1 of the first transistor T1 is located on the side of the second electrode D2 of the first transistor T1; in the second direction, in each second transistor T2, the first electrode S2 of the second transistor T2 is located on the side of the second electrode D2 of the second transistor T2. That is, the first electrode S1 and the second electrode D2 of the first transistor T1 are arranged along the second direction, and the first electrode S2 and the second electrode D2 of the second transistor T2 are also arranged along the second direction. In this way, it is possible to further avoid increasing the width of the first transistor T1 in the first direction and the width of the second transistor T2 in the first direction, thereby minimizing the influence of the setting of the control circuit on the aperture ratio.
[0195] In some embodiments, when the display panel is a liquid crystal display panel, the sub-pixel includes a driving transistor; the first conductive layer further includes: a control stage of the driving transistor electrically connected to the scan line 2;
[0196] The second conductive layer also includes: a first electrode of the driving transistor;

[0198] In a specific implementation, the first electrode and the second electrode of the driving transistor are located in different conductive layers, and the first electrode and the second electrode of each transistor of the control circuit and the control signal line are located in different conductive layers, thereby reducing the distance between the second electrode of the driving transistor and the data line and reducing the distance between the first electrode and the second electrode of each transistor of the control circuit and the control signal line, without causing a short circuit between the second electrode of the driving transistor and the data line, or between the first electrode and the second electrode of each transistor of the control circuit and the control signal line, thereby reducing the difficulty of display panel layout design.
[0199] In some embodiments, the display panel further includes: a pixel electrode layer located on the side of the third conductive layer away from the second conductive layer 15, and a common electrode layer located on the side of the pixel electrode layer away from the third conductive layer.

Among them, Figure 6 , Figure 7 , Fig. 9 , Fig.11 , Fig.13 The patterns of the second light shielding layer 16, the active layer 18, the first interlayer insulating layer 19, the second interlayer insulating layer 20, and the first planarizing layer 22 are respectively, Fig. 9 , Fig.11 , Fig.13 The dotted line area is the area of the via holes of the first interlayer insulating layer 19 , the second interlayer insulating layer 20 , and the first planarizing layer 22 .
[0201] In some embodiments, Figure 5 As shown, the third conductive layer further includes: a first input lead 23, a second input lead 24, a first output lead 25, and a second output lead 26. The first input lead 23 is electrically connected to the first electrode S1 of the first transistor T1, and is electrically connected to the scan signal input line 7 through a via hole penetrating the second interlayer insulating layer and the first interlayer insulating layer. The second input lead 24 is electrically connected to the first electrode S2 of the second transistor T2, and is electrically connected to the fixed potential line 9 through a via hole penetrating the second interlayer insulating layer and the first interlayer insulating layer. The first output lead 25 is electrically connected to the second electrode D2 of the first transistor T1, and is electrically connected to the scan line 2 through a via hole penetrating the second interlayer insulating layer and the first interlayer insulating layer, and the second output lead 26 is electrically connected to the second electrode D2 of the second transistor T2, and is electrically connected to the scan line 2 through a via hole penetrating the second interlayer insulating layer and the first interlayer insulating layer. The first input lead 23, the second input lead 24, the first output lead 25, and the second output lead 26 all extend along the second direction Y.
[0202] In a specific implementation, the first input lead 23 is integrally connected to the first electrode S1 of the first transistor T1. The second input lead 24 is integrally connected to the first electrode S2 of the second transistor T2. The first output lead 25 is integrally connected to the second electrode D2 of the first transistor T1. The second output lead 26 is integrally connected to the second electrode D2 of the second transistor T2.
[0203] In some embodiments, the first control signal line 12 is electrically connected to the control electrode G1 of the first transistor T1 through a via hole penetrating the first interlayer insulating layer. The second control signal line 13 is electrically connected to the control electrode G2 of the second transistor T2 through a via hole penetrating the first interlayer insulating layer. The first electrode S1 and the second electrode D2 of the first transistor T1, and the first electrode S2 and the second electrode D2 of the second transistor T2 are electrically connected to the active layer through a via hole penetrating the second interlayer insulating layer, the first interlayer insulating layer and the gate insulating layer. The pixel electrode is electrically connected to the second electrode of the driving transistor through a via hole penetrating the first planarizing layer.

[0204] In some embodiments, the control circuit array is arranged so that the control stages of the first transistors in the same column in the second direction are electrically connected to the same first control signal line, and the control stages of the second transistors in the same column in the second direction are electrically connected to the same second control signal line. The first electrodes of the first transistors in the same row in the first direction are electrically connected to the same scan signal input line, and the first electrodes of the second transistors in the same row in the first direction are electrically connected to the same fixed potential line.
[0205] In some embodiments, Fig.16 As shown, the first light shielding layer in the opposite substrate includes a plurality of first light shielding portions 36 extending along the first direction X and a plurality of second light shielding portions 37 extending along the second direction Y. Among them, the first light shielding portion 36 covers the space between adjacent sub-pixel rows, that is, the first light shielding portion 36 covers the scanning line, the fixed potential line and the scanning signal input line. When the sub-pixels arranged in the first direction X have the same color, the second light shielding portion 37 only covers the space between the sub-pixel columns provided with the control circuit, that is, the second light shielding portion covers the control circuit, the control signal line and each input lead and output lead. There is no need to set the second light shielding portion between the sub-pixel columns without the control circuit, so that the sub-pixel aperture ratio can be increased as much as possible while shielding the control circuit and the control.
[0206] Or, in some embodiments, Figure 3 As shown, the control circuit 10 is located between two adjacent sub-pixels 4 in the second direction Y;
[0207] The plurality of fixed potential lines 9 extend along the second direction Y and are arranged along the first direction X.
[0208] That is, the control circuit 10 is located between adjacent sub-pixel rows.
[0209] In some embodiments, the control circuits corresponding to each pixel island are arranged in a row in the first direction X.
[0210] In some embodiments, control electrodes of first transistors arranged in a row in the second direction are electrically connected to the same first control signal line. Control electrodes of second transistors arranged in a row in the second direction are electrically connected to the same second control signal line, and first electrodes of second transistors arranged in a row in the second direction are electrically connected to the same fixed potential line.
[0211] Next, the structure of the display panel is described by taking the example that the control circuit is located between adjacent sub-pixel rows.
[0212] In some embodiments, Fig.17 As shown, the display panel specifically includes:
[0213] The first conductive layer 14 includes a scan line 2, a control electrode G1 of the first transistor T1, and a control electrode G2 of the second transistor T2;
[0214] The second conductive layer 15 is located on the side of the first conductive layer 14 away from the first substrate, and includes a scanning signal input line 7;
[0215] The third conductive layer 17 is located on a side of the second conductive layer 15 away from the first conductive layer 14 and includes the data line 3;
[0216] The fourth conductive layer 38 is located on the side of the third conductive layer 17 away from the second conductive layer 15, and includes a control signal line 8, a fixed potential line 9, a first electrode S1 and a second electrode D1 of the first transistor T1, and a first electrode S2 and a second electrode D2 of the second transistor T2; the orthographic projections of the control signal line 8 and the fixed potential line 9 on the first substrate overlap with a partial area of the orthographic projection of the data line 3 on the first substrate.
[0217] in, Fig. 20 , Fig.21 , Fig.23 , Fig.26 Shown respectively with Fig.17 The corresponding patterns of the first conductive layer 14 , the second conductive layer 15 , the third conductive layer 17 , and the fourth conductive layer 38 .
[0218] It should be noted that Fig.17 This is a pattern of a partial area within a control area, so the disconnected area between the sub-scanning lines is not shown.
[0219] In a specific implementation, since the control signal line, the fixed potential line and the data line are located in different conductive layers, the orthographic projections of the control signal line and the fixed potential line on the first substrate overlap with part of the orthographic projections of the data line on the first substrate, thereby avoiding the signal lines electrically connected to the control circuit from affecting the sub-pixel aperture ratio.
[0220] In some embodiments, the subpixel includes a drive transistor;
[0221] The first conductive layer also includes: a control stage of a drive transistor electrically connected to the scan line;
[0222] The second conductive layer also includes: a first electrode of the driving transistor;
[0223] like Fig.17 , Fig.28 As shown, the display panel also includes:
[0224] The fifth conductive layer 42 is located on a side of the fourth conductive layer 38 away from the third conductive layer 17 and includes the second electrode D3 of the driving transistor.
[0225] in, Fig.28 For Fig.17 The corresponding pattern of the fifth conductive layer 42 .
[0226] In a specific implementation, the first electrode and the second electrode of the driving transistor are located in different conductive layers, thereby reducing the distance between the second electrode of the driving transistor and the data line without causing a short circuit between the second electrode of the driving transistor and the data line, thereby reducing the difficulty of display panel layout design.
[0227] In some embodiments, the display panel further includes: a pixel electrode layer located on the side of the fifth conductive layer away from the fourth conductive layer, and a common electrode layer located on the side of the pixel electrode layer away from the fifth conductive layer. The pixel electrode layer includes pixel electrodes corresponding to the sub-pixels one by one. The common electrode layer includes a common electrode. It should be noted that in order to facilitate the clear illustration of the structure of the control circuit, Fig.17 The patterns of the common electrode layer and the pixel electrode layer are not shown. In a specific implementation, the pattern of the pixel electrode layer 21 is as follows: Fig.30 As shown, the pattern of the common electrode layer 35 is as shown in Fig.31 shown.
[0228] It should be noted that the pixel electrode layer and the common electrode layer can be made of materials with higher transmittance. The pixel electrode layer and the common electrode layer can include, for example, indium tin oxide (ITO). That is, the array substrate can be provided with two layers of ITO layers. The first layer of ITO is used as the pixel electrode layer, so that the number of vias can be reduced and the aperture ratio can be improved. In some embodiments, the display panel also includes a metal common electrode line located in the same layer as the common electrode. In a specific implementation, for example, a common electrode line is formed on the second passivation layer, and then an ITO common electrode electrically connected to the common electrode line is formed.
[0229] In some embodiments, Fig.17 , Fig.18 , Fig.19 , Fig. 22 , Fig.24 , Fig.25 , Fig. 27 , Fig.29 , Fig.32 , Fig.33 As shown, the display panel further includes a second light shielding layer 16 between the first conductive layer 14 and the first substrate, an active layer 18 between the second light shielding layer 16 and the first conductive layer 14, a buffer layer 27 between the active layer 18 and the second light shielding layer 16, a first gate insulating layer 28 between the first conductive layer 14 and the active layer 18, a second gate insulating layer 29 between the first conductive layer 14 and the second conductive layer 15, a first interlayer insulating layer 19 between the second conductive layer 15 and the third conductive layer 17, a second interlayer insulating layer 20 between the third conductive layer 17 and the fourth conductive layer 38, a third interlayer insulating layer 43 between the fourth conductive layer 38 and the fifth conductive layer 42, a first passivation layer 44 between the fifth conductive layer and the pixel electrode layer, and a second passivation layer 30 between the pixel electrode layer and the common electrode layer. Among them, Fig.18 , Fig.19 , Fig. 22 , Fig. 27 , Fig.29 They are patterns of the second light shielding layer 16 , the active layer 18 , the first interlayer insulating layer 19 , the third interlayer insulating layer 43 , and the first passivation layer 44 . Fig.32 For along Fig.17 The cross-sectional view of AA', Fig.33 For along Fig.17 Cross-sectional view of BB'. Fig. 22 , Fig. 27 , Fig.29 The dotted line areas are the via holes of the first interlayer insulating layer 19 , the third interlayer insulating layer 43 , and the first passivation layer 44 . Fig.24 , Fig.25 The middle dotted line area corresponds to the area where the via hole is formed after the second interlayer insulating layer 20 is formed.
[0230] In a specific implementation, the second interlayer insulating layer plays the role of a planarizing layer. After forming the second interlayer insulating layer 20, first Fig.24 The dotted line area shown in FIG. 1 is subjected to a first patterning process to form a via hole. Then, based on the via hole formed by the first patterning process, a second patterning process is performed in the following manner: Fig.25 The dotted line area shown in the figure is subjected to a second patterning process to form a via hole. It should be noted that after forming the first interlayer insulating layer, the Fig.25 The dotted area shown in FIG. 1 forms a via hole, so that Fig.25 The dotted line area shown in the figure is subjected to a second patterning process, and corresponding via holes can be formed in the first interlayer insulating layer and the film layer below it, and the fourth conductive layer can be subsequently formed through the Fig.25 The via hole formed in the dashed area is electrically connected to the active layer or the first conductive layer.
[0231] In some embodiments, Fig.17 As shown, the first transistor T1 and the second transistor T2 in each control circuit are arranged in a row in the first direction.
[0232] In some embodiments, Fig.17 As shown, in each first transistor, the first electrode S1 of the first transistor T1, the control stage G1 of the first transistor T1 and the second electrode D1 of the first transistor T1 are arranged along the first direction;
[0233] In each second transistor T2 , the first electrode S1 of the second transistor T2 , the control stage G1 of the second transistor T2 , and the second electrode D1 of the second transistor T are arranged along the first direction.
[0234] That is, when the first transistor and the second transistor in each control circuit are arranged in a row in the first direction X, the first electrode, the control electrode, and the second electrode of each transistor in the control circuit are also arranged in a row in the first direction X, thereby reducing the size of the control circuit in the second direction Y, and further avoiding the influence of the control circuit on the sub-pixel aperture ratio.
[0235] In some embodiments, Fig.17As shown, the active layer of the first transistor T1 includes a portion extending along the first direction;
[0236] The active layer of the second transistor T2 includes a portion extending along the first direction.
[0237] In some embodiments, Fig.17 , Fig.26 As shown, the fourth conductive layer 38 further includes: a plurality of first output leads 25 and a plurality of second output leads 26 extending along the second direction Y;
[0238] The second electrode D1 of the first transistor T1 is electrically connected to the scan line 2 through the first output lead 25;
[0239] The second electrode D2 of the second transistor T2 is electrically connected to the scan line 2 through the second output lead 26;
[0240] The orthographic projections of the first output lead 25 and the second output lead 26 on the first substrate overlap a portion of the orthographic projection of the data line 3 on the first substrate.
[0241] In a specific implementation, since the first output lead, the first input lead and the second input lead are located in different conductive layers with the data line, the orthographic projections of the first output lead, the first input lead and the second input lead on the first substrate overlap with a partial area of the orthographic projection of the data line on the first substrate, thereby avoiding the signal lines electrically connected to the control circuit from affecting the sub-pixel aperture ratio.
[0242] In some embodiments, Fig.17 , Fig.26 As shown, the fourth conductive layer 38 further includes: a first input lead 23 , and the first electrode S1 of the first transistor T1 is electrically connected to the scan signal input line 7 through the first input lead 23 .
[0243] In some embodiments, Fig.17 , Fig.26 As shown, the fourth conductive layer 38 further includes: a plurality of first connection pads 39, a plurality of second connection pads 40, a plurality of third connection pads 41, a plurality of fourth connection pads 45, and a plurality of fifth connection pads 46. The first input lead 23 is electrically connected to the first connection pad 39, and the first connection pad 39 is electrically connected to the scan signal input line 7 through a via hole penetrating the second interlayer insulating layer and the first interlayer insulating layer. Fig.32As shown, the first output lead 25 is electrically connected to the second connection pad 40, and the second connection pad 40 is electrically connected to the scan line 2 through the via 33 penetrating the second interlayer insulating layer 20, the first interlayer insulating layer 19, and the second gate insulating layer 29. The first control signal line 12 is electrically connected to the third connection pad 41, and the third connection pad 41 is electrically connected to the control stage of the first transistor through the via penetrating the second interlayer insulating layer, the first interlayer insulating layer, and the second gate insulating layer. The second control signal line 13 is electrically connected to the fourth connection pad 45, and the fourth connection pad 45 is electrically connected to the control stage of the second transistor through the via penetrating the second interlayer insulating layer, the first interlayer insulating layer, and the second gate insulating layer. The second output lead 26 is electrically connected to the fifth connection pad 46, and the fifth connection pad 46 is electrically connected to the scan line through the via penetrating the second interlayer insulating layer, the first interlayer insulating layer, and the second gate insulating layer.
[0244] In some embodiments, Fig.32 As shown, the second connection pad 40 is electrically connected to the scanning line 2 through the fourth via hole 33 that penetrates the second interlayer insulating layer 20, the first interlayer insulating layer 19, and the second gate insulating layer 29. In a specific implementation, after the second interlayer insulating layer 20 is formed, a patterning process is first performed in the area corresponding to the fourth via hole 33 to form a via hole in the second interlayer insulating layer 20, and then a second patterning process is performed to form a via hole in the first interlayer insulating layer 19 and the second gate insulating layer 29. The via hole size h1 of the second interlayer insulating layer 20 is larger than the via hole size of the second gate insulating layer 29. Accordingly, the second connection pad 40 extends in a stepped shape in the area of the fourth via hole 33, and the size of the plane area of the second connection pad 40 at the via hole of the second gate insulating layer 29 is h2. In a specific implementation, h1 is, for example, 4 microns, and h2 is, for example, 2.5 microns.
[0245] In some embodiments, Fig.33As shown, the second electrode D3 of the driving transistor is electrically connected to the active layer 18 through a via hole penetrating the third interlayer insulating layer 43, the second interlayer insulating layer 20, the first interlayer insulating layer 19, the second gate insulating layer 29, and the first gate insulating layer 28. The second connection pad 40 is electrically connected to the scan line 2 through a via hole penetrating the second interlayer insulating layer 20, the first interlayer insulating layer 19, and the second gate insulating layer 29. In the region where the second electrode D3 of the driving transistor is electrically connected to the active layer 18, the first interlayer insulating layer 19, the second gate insulating layer 29, and the first gate insulating layer 28 have a first via hole 55, and in the region where the second connection pad 40 is electrically connected to the scan line 2, the first interlayer insulating layer 19 and the second gate insulating layer 29 have a second via hole 32; in the region where the second electrode D3 of the driving transistor is electrically connected to the active layer 18 and in the region where the second connection pad 40 is electrically connected to the scan line 2, the second interlayer insulating layer 20 has a third via hole 34 exposing the first via hole 55 and the second via hole 32. In a specific implementation, when two patterning processes are required to form vias after forming the second interlayer insulating layer 20, a patterning process is first performed to remove the second interlayer insulating layer 20 in the area of the third via 34, and then a second patterning process is performed to form the second via 32. In a specific implementation, the dimension h4 of the first via 55 exposing the active layer 18 is, for example, 3 microns. The distance h3 between the edge of the first via 55 exposing the active layer 18 and the edge of the second interlayer insulating layer 20 exposing the first interlayer insulating layer 19 is, for example, 1.5 microns. The distance h5 between the edge of the first via 55 exposing the active layer 18 and the scan line is, for example, 2.05 microns. The dimension h6 of the second via 32 exposing the scan line 2 is, for example, 2.5 microns, and the distance h7 between the edge of the second via 32 exposing the scan line 2 and the scan signal input line 7 is, for example, 2.5 microns.
[0246] In some embodiments, the display panel further comprises:
[0247] an opposite substrate, located at a side of the support portion away from the common electrode layer, and comprising a light shielding portion;
[0248] The liquid crystal layer is located between the opposite substrate and the common electrode layer.
[0249] In some embodiments, the opposite substrate includes a first light shielding layer, and the first light shielding layer includes a light shielding portion. When the display panel is a liquid crystal display panel, the sub-pixels arranged in the first direction X have the same color, and the control circuit is located between adjacent sub-pixel rows, such as Fig.34As shown, the light shielding portion of the first light shielding layer in the counter substrate may only include a plurality of first light shielding portions 36 extending along the first direction X. The first light shielding portions 36 cover between adjacent sub-pixel rows, that is, the first light shielding portions 36 cover the scanning lines, the fixed potential lines, the scanning signal input lines, and the control circuit. Since no control circuit is provided between sub-pixel columns, and the positive projections of each control signal line, each fixed potential line, each input sub-lead, and each output sub-lead overlap with a partial area of the scanning line, there is no need to provide a second light shielding portion between sub-pixel columns, thereby improving the sub-pixel aperture ratio.
[0250] In some embodiments, Fig.34 As shown, the display panel also includes:
[0251] A plurality of support portions 47 are located on a side of the common electrode layer away from the pixel electrode layer. The orthographic projection of the support portion 47 on the first substrate is located between adjacent sub-pixel rows 6 , and the control circuit is located between the sub-pixel rows where the support portions 47 are provided.
[0252] In some embodiments, Fig.34 As shown, each pixel island 5 includes: a first sub-pixel row 48, a second sub-pixel row 49 and a third sub-pixel row 50;
[0253] The first sub-pixel row 48 includes a plurality of first color sub-pixels arranged along a first direction X;
[0254] The second sub-pixel row 49 includes a plurality of second color sub-pixels arranged along the first direction X;
[0255] The third sub-pixel row 50 includes a plurality of third color sub-pixels arranged along the first direction X;
[0256] In some embodiments, Fig.34 As shown, in the second direction Y, the width of the first light shielding portion 36 covering between the first sub-pixel row 48 and the second sub-pixel row 49, and the width of the first light shielding portion 36 covering between the second sub-pixel row 49 and the third sub-pixel row 50 are both smaller than the width of the first light shielding portion 36 covering between the first sub-pixel row 48 and the third sub-pixel row 50;
