Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel. Background Art

[0002] With the development of display technology, flat display devices such as liquid crystal displays (LCD) have been widely used in various consumer electronic products such as mobile phones, televisions, personal digital assistants, digital cameras, laptops, desktop computers, etc. due to their advantages of high image quality, power saving, thin body and wide application range, becoming the mainstream of display devices.

[0003] According to the different orientation modes of liquid crystal, the LCD panels on the mainstream market can be divided into the following types: Vertical Alignment (VA), Twisted Nematic (TN), Super Twisted Nematic (STN), In-Plane Switching (IPS), and Fringe Field Switching (FFS). Among them, FFS LCD panels have the advantages of high penetration and wide viewing angle, and have been widely used in small and medium-sized displays.

[0004] The High Transmittance Ratio Field Switching (HFS) display mode belongs to a type of FFS type. It not only has the advantages of high penetration and wide viewing angle of FFS type liquid crystal display panels, but also has excellent viewing angle image quality and low energy efficiency display characteristics. However, in the HFS display mode, since its liquid crystal rotates horizontally under the action of the electric field, the elastic constant that affects its response speed is the twist elastic constant (K22), which is more than 50% lower than the splay elastic constant (K11) and the bending elastic constant (K33). The technical solution for improving the response speed of the HFS display mode is generally to reduce the viscosity of the liquid crystal and the liquid crystal cell thickness (Cell gap), such as reducing the liquid crystal cell thickness from 2.3 to 2.5um to 2.0um, but the viscosity of the liquid crystal material has certain limitations, and reducing the liquid crystal cell thickness to 2.0um will result in a lower yield during mass production.

[0031] The following descriptions of the embodiments are with reference to the attached diagrams to illustrate specific embodiments that the present application can be implemented in. The directional terms mentioned in the present application, such as [up], [down], [front], [back], [left], [right], [inside], [outside], [side], etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present application, rather than to limit the present application. In the figures, units with similar structures are represented by the same reference numerals. In the accompanying drawings, the thickness of some layers and regions is exaggerated for clear understanding and ease of description. That is, the size and thickness of each component shown in the drawings are arbitrarily shown, but the present application is not limited to this.

[0032] Please refer to Figures 1 to 3 , Figure 1 A schematic diagram of a cross-sectional structure of a display panel provided in an embodiment of the present application, Figure 2 A partial planar structural diagram of a display panel provided in an embodiment of the present application, Figure 3 for Figure 2 A detailed structural diagram of the M in the figure. Figure 1 The display panel 100 includes a first substrate 1 and a second substrate 2 arranged opposite to each other, and a liquid crystal layer 3 and a sealant 4 arranged between the first substrate 1 and the second substrate 2, and the sealant 4 surrounds the liquid crystal layer 3. Optionally, the first substrate 1 is an array substrate, and the second substrate 2 is a color filter substrate. Of course, the present application is not limited thereto. In the present application, the color filter on the second substrate 2 can also be arranged on the first substrate 1. In this case, the second substrate 2 only serves as an opposing substrate.

[0033] The liquid crystal layer 3 includes a plurality of chiral liquid crystal molecules arranged in a spiral structure, and the pitch of the chiral liquid crystal molecules is 40 microns to 300 microns, such as 40 microns, 50 microns, 60 microns, 80 microns, 100 microns, 130 microns, 150 microns, 180 microns, 190 microns, 200 microns, 260 microns, 300 microns, etc. The chiral liquid crystal molecules can be formed by adding a chiral agent to a positive liquid crystal. When a chiral agent is added to a liquid crystal, the liquid crystal molecules form a spiral structure. The content of the chiral agent affects the pitch of the spiral structure. The structure and content of the chiral agent are designed by setting the pitch of the chiral liquid crystal molecules to 40 microns to 300 microns. In this way, by making the liquid crystal layer 3 adopt chiral liquid crystal molecules arranged in a spiral structure and utilizing the increased twisting force of the liquid crystal molecules, the twisting elastic constant (K22) of the liquid crystal molecules can be improved, thereby improving the response speed of the liquid crystal, thereby eliminating the need to adjust the viscosity of the liquid crystal molecules and the thickness of the liquid crystal box, so that the thickness of the liquid crystal box of the present application can be maintained above 2.3 microns, that is, the distance of the gap between the first substrate 1 and the second substrate 2 is greater than or equal to 2.3 microns.

[0034] Reference Figure 2 , the first substrate 1 includes a plurality of data lines DL arranged at intervals in a first direction X and a plurality of scan lines SL arranged at intervals in a second direction Y, and each of the scan lines SL extends along the first direction X. The data lines DL and the scan lines SL intersect to define a plurality of pixel opening areas PA. Among them, the first direction X and the second direction Y are different, for example, the first direction X is a row direction, and the second direction Y is a column direction. At this time, the first direction X and the second direction Y are perpendicular. Of course, the present application is not limited thereto. The first direction X and the second direction Y of the present application may also intersect to form an angle of other angles.

[0035] The display panel 100 further includes a plurality of display pixels P arranged in a multi-array, each of the display pixels P includes a plurality of sub-pixels SP, and each of the sub-pixels SP corresponds to one of the pixel opening areas PA. For example, each of the display pixels P includes three sub-pixels SP, and the three sub-pixels SP are respectively used to display different colors. For example, the three sub-pixels SP are respectively a first sub-pixel R, a second sub-pixel G, and a third sub-pixel B. The first sub-pixel R is used to display red, the second sub-pixel G is used to display green, and the third sub-pixel B is used to display blue, so that each of the display pixels P can display different colors, thereby realizing color display of the display panel 100.

[0036] A plurality of the sub-pixels SP are arranged in a sub-pixel row in the first direction X, and a plurality of the sub-pixels SP are arranged in a sub-pixel column in the second direction Y. Optionally, two adjacent sub-pixels SP in the sub-pixel row are used to display different colors, and two adjacent sub-pixels SP in the sub-pixel column are used to display the same color, that is, the plurality of sub-pixels SP of each display pixel P are arranged alternately in the first direction X.

[0037] Optionally, in the second direction Y, the data line DL is arranged as a plurality of folded line segments, that is, the data line DL is arranged in a step shape, and the data line DL is arranged obliquely in the second direction Y to form a certain angle with the alignment direction of the chiral liquid crystal molecules, and ensures that the sub-pixels SP in each column are basically arranged at intervals in the second direction Y. Specifically, each of the data lines DL includes a straight portion DL1 and a bent portion DL2 connecting two adjacent straight portions DL1, the two adjacent straight portions DL1 have the same extension direction, the bent portion DL2 is arranged corresponding to the scan line SL, the extension direction of the bent portion DL2 is the same as the extension direction of the scan line SL, and in the second direction, the two adjacent bent portions DL2 at least partially overlap, so that the sub-pixels SP on the same sub-pixel column are staggered in the second direction Y, and the adjacent sub-pixels SP have a larger overlapping area in the second direction Y, so that the sub-pixels SP in each column are basically arranged in the second direction Y.

[0038] Reference Figure 2 and Figure 3 , the first substrate 1 further includes a first electrode layer 10 and a second electrode layer 20, optionally, the metal layer where the data line DL is located is located above the metal layer where the scan line SL is located, the first electrode layer 10 is located above the metal layer where the data line DL is located, and the second electrode layer 20 is located above the first electrode layer 10, that is, the first electrode layer 10 is located on the side of the metal layer where the data line DL is located away from the metal layer where the scan line SL is located, and the second electrode layer 20 is located on the side of the first electrode layer 10 away from the metal layer where the data line DL is located. Of course, the present application is not limited to this, and the positional relationship between the first electrode layer 10 and the second electrode layer 20 in the present application can also be interchanged.

[0039] The first electrode layer 10 includes a first electrode pattern 11 patterned in the pixel opening area PA, the first electrode pattern 11 is a block electrode, and adjacent first electrode patterns 11 are arranged at intervals. That is, the first electrode layer 10 includes a plurality of first electrode patterns 11 arranged in an array, each first electrode pattern 11 corresponds to one pixel opening area PA, and each first electrode pattern 11 is insulated from each other, so that each first electrode pattern 11 corresponds to one sub-pixel SP separately, and is used to control the display of the corresponding sub-pixel SP.

[0040] The second electrode layer 20 includes a plurality of first electrode wires 21 arranged corresponding to the first electrode pattern 11, and the extension directions of the plurality of first electrode wires 21 corresponding to the same first electrode pattern 11 are the same. A slit 210 is formed between two adjacent first electrode wires 21, and the extension directions of the plurality of slits 210 corresponding to the same first electrode pattern 11 are the same, that is, the slit angles of the plurality of slits 210 corresponding to the same first electrode pattern 11 are the same. Each of the sub-pixels SP includes a first electrode pattern 11 and a plurality of first electrode wires 21 corresponding to the first electrode pattern 11. Since the extension directions of the plurality of first electrode wires 21 of the same first electrode pattern 11 are the same, each of the sub-pixels SP forms a single-domain display to match the rotation of the chiral liquid crystal molecules arranged in a spiral structure.

[0041] The second electrode layer 20 further includes a second electrode wire 22 arranged corresponding to the data line DL and a third electrode wire 23 located at both ends of the first electrode wire 21. The third electrode wire 23 connects the first electrode wire 21 and the second electrode wire 22, so that the first electrode wires 21 in each of the sub-pixels SP are connected together to form the second electrode layer 20 arranged on the entire surface. The second electrode layer 20 is provided with a hollow structure at a position corresponding to the first electrode pattern 11 in each of the sub-pixels SP to form the slit 210. At this time, the electrical signals on the first electrode wire 21 in each of the sub-pixels SP are the same, the first electrode wire 21 serves as a common electrode, and the first electrode pattern 11 serves as a pixel electrode.

[0042] The extension direction of the first electrode wiring 21 is the same as the extension direction of the straight portion DL1 on the data line DL, the extension direction of the second electrode wiring 22 is the same as the extension direction of the first electrode wiring 21, and the extension direction of the third electrode wiring 23 is the same as the extension direction of the bent portion DL2 on the data line DL, that is, the extension direction of the third electrode wiring 23 is the same as the extension direction of the scanning line SL. The line width of the second electrode wiring 22 is greater than the line width of the first electrode wiring 21, and the line width of the second electrode wiring 22 is also greater than the line width of the data line DL, so that the second electrode wiring 22 can completely cover the data line DL.

[0043] The liquid crystal layer 3 is arranged on the side of the first electrode layer 10 and the second electrode layer 20 close to the second substrate 2, and a horizontal electric field is formed between the first electrode pattern 11 of the first electrode layer 10 and the first electrode wiring 21 of the second electrode layer 20, so as to rotate the chiral liquid crystal molecules of the liquid crystal layer 3, thereby realizing the control of light. The first electrode layer 10, the second electrode layer 20, the data line DL and the scanning line SL are all located on the first substrate 1. Of course, the first substrate 1 also includes a substrate and a plurality of thin film transistors arranged on the substrate, each of the sub-pixels SP may include at least one thin film transistor, and the thin film transistor includes a source, a drain and a gate, wherein the source may be electrically connected to the data line DL, the gate may be electrically connected to the scanning line SL, and the drain may be electrically connected to the first electrode pattern 11, so as to provide a driving signal to the first electrode pattern 11, so as to form a horizontal electric field between the first electrode pattern 11 and the corresponding first electrode wiring 21.

[0044] In one embodiment, see Figure 4 , Figure 4 for Figure 3 A local detail structure diagram at N in FIG. Figure 4 and Figure 3 , taking the first sub-pixel R and the second sub-pixel G in each display pixel P as an example, the angle between the first electrode wiring 21 in the first sub-pixel R and the parallel line BB' of the scanning line SL is a first angle a, and the angle between the first electrode wiring 21 in the second sub-pixel G and the parallel line BB' is a second angle b, and the first angle a is different from the second angle b, so as to improve the large viewing angle color deviation problem caused by the single domain design of the sub-pixel SP. The range of the first angle a and the second angle b are both 65° to 87°, such as 65°, 68°, 70°, 72°, 75°, 78°, 80°, 83°, 85°, 87°, etc. For another example, the first angle a is 65°, the second angle b is 80°, and the first angle a is greater than the second angle b.

[0045] The parallel line BB' is a virtual straight line parallel to the scan line SL, and the extension direction of the parallel line BB' is the same as the extension direction of the scan line SL, that is, the parallel line BB' is parallel to the scan line SL and the first direction X. The angle between the first electrode line 21 and the parallel line BB' is equal to the angle between the extension line of the first electrode line 21 and the scan line SL, so Figure 4In FIG. 1 , the angle between the parallel line BB′ and the first electrode wiring 21 represents the angle between the extension line of the first electrode wiring 21 and the scanning line SL.

[0046] In other words, in the second direction Y, the first electrode wiring 21 is tilted, and the tilt angle of the first electrode wiring 21 in the second direction Y is 3° to 25°, that is, the angle between the extension direction of the first electrode wiring 21 and the second direction Y is 3° to 25°, and the second direction Y is perpendicular to the extension direction of the scanning line SL. In this way, in the same sub-pixel SP, the slit angle of the slit 210 formed by two adjacent first electrode wirings 21 ranges from 3° to 25°. The slit angle of the slit 210 is also the angle between the extension direction of the slit 210 and the second direction Y.

[0047] It should be noted that Figure 4 In order to illustrate the differentiated design of the first electrode wiring 21 in each sub-pixel SP and the positional relationship between the first electrode wiring 21 and the scanning line SL, Figure 4 FIG. 2 schematically shows a partial structure of the second electrode layer 20 , Figure 4 The structure of the second electrode layer 20 not shown in the figure can be referred to Figure 3 , such as the second electrode wiring 22 and the third electrode wiring 23.

The third angle is in the range of 65° to 87°, such as 65°, 68°, 70°, 72°, 75°, 78°, 80°, 83°, 85°, 87°, etc.

[0049] In one embodiment, continue to refer to Figure 4, the interval between the adjacent first electrode lines 21 in the first sub-pixel R is a first interval 201, and the interval between the adjacent first electrode lines 21 in the second sub-pixel G is a second interval 202, and the interval distance L1 of the first interval 201 is different from the interval distance L2 of the second interval 202, so as to further improve the large viewing angle color deviation problem caused by the single-domain design of the sub-pixel SP, for example, the interval distance L1 of the first interval 201 is greater than the interval distance L2 of the second interval 202. Optionally, in the first sub-pixel R, the interval distance L1 between any two adjacent first intervals 201 is equal, and in the second sub-pixel G, the interval distance L2 between any two adjacent second intervals 202 is equal, that is, the first electrode lines 21 in the first sub-pixel R are evenly arranged, and the first electrode lines 21 in the second sub-pixel G are also evenly arranged.
