Display panel and display device

Abstract

The present invention provides a display panel and a display device, wherein the display panel has a plurality of pixel areas, wherein heating lines are only arranged in correspondence with at least a portion of the pixel areas with the lowest light transmittance, while heating lines are not arranged in correspondence with other pixel areas. Obviously, the light transmittance of the pixel areas without heating lines is not affected by the heating lines, and the pixel areas with the lowest light transmittance have the lowest light transmittance themselves, so even if heating lines are arranged in correspondence, the influence of the heating lines on the light transmittance of the pixel areas with the lowest light transmittance will be relatively small. Therefore, when the arrangement of the heating lines can realize heating of the liquid crystal, the influence of the heating lines on the display effect of the display panel can be minimized.

Description

Technical Field

[0001] The present invention relates to the field of display technology, and more particularly to a display panel and a display device. Background Art

[0002] The LCD panel relies on the liquid crystal to display the screen. In a normal temperature working environment, the liquid crystal maintains a normal liquid crystal structure with good fluidity, which can meet the needs of normal display. When the working environment temperature of the LCD panel is too low, the viscosity coefficient of the liquid crystal increases, the threshold voltage increases, and the response speed slows down, which will cause dynamic smearing on the display screen. Generally, in an environment below minus 40℃, the liquid crystal may even solidify, the liquid crystal state disappears, and the LCD display may not work.

[0003] Based on this, currently most of the liquid crystal display panels are provided with corresponding heating wirings to heat the liquid crystal in the liquid crystal display panel under certain circumstances, so as to ensure that the liquid crystal display panel can display a better picture.

[0004] However, currently, the heating wiring in the liquid crystal display panel is arranged in each pixel area, so that the light transmittance of each pixel area is affected by the heating wiring, thereby finally affecting the display effect of the liquid crystal display panel. Summary of the invention

[0005] In view of this, in order to solve the above problems, the present invention provides a display panel and a display device, and the technical solutions are as follows:

[0006] A display panel, the display panel having a plurality of pixel regions, the pixel regions including a first pixel region and a second pixel region, the display panel comprising:

[0007] A color filter substrate and an array substrate arranged opposite to each other, and a liquid crystal layer located between the color filter substrate and the array substrate;

[0008] The color filter substrate includes a plurality of color resists, the color resists extend along a first direction and are sequentially arranged along a second direction, the color resists include a first color resist and a second color resist, the first color resist corresponds to a first pixel region, the second color resist corresponds to a second pixel region, and the light transmittance of the first color resist is less than the light transmittance of the second color resist; the first direction intersects with the second direction, and are respectively parallel to the plane where the color filter substrate is located;

[0009] The display panel further includes a heating line, which is stacked with at least a portion of the first color resist along a third direction, and extends along the first direction; the third direction is perpendicular to the plane where the array substrate is located.

[0010] The present invention further provides a display device, which includes the above-mentioned display panel.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] A display panel provided by the present invention has multiple pixel areas, and heating lines are only set in at least part of the pixel areas with the lowest light transmittance, and no heating lines are set in other pixel areas. Obviously, the light transmittance of these pixel areas without heating lines is not affected by the heating lines, and the pixel areas with the lowest light transmittance have the lowest light transmittance themselves. Therefore, even if heating lines are set accordingly, the influence of the heating lines on the light transmittance of the pixel areas with the lowest light transmittance will be relatively small. Therefore, the setting of the heating lines can achieve heating of the liquid crystal and minimize the influence of the heating lines on the display effect of the display panel.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Based on the content recorded in the background technology, the heating lines in the current liquid crystal display panel are set in each pixel area, that is to say, whether it is a pixel area that emits red light, a pixel area that emits green light, a pixel area that emits blue light, or other pixel areas, a corresponding heating line will be set, resulting in the light transmittance of each pixel area being affected by the heating line. Therefore, although this technology realizes the heating of the liquid crystal, it will affect the display effect of the display panel.

[0032] Based on this, a novel display panel structure is provided in an embodiment of the present invention, and the layout of the heating lines is reasonably designed. While heating of the liquid crystal can be achieved, the influence of the heating lines on the display effect of the display panel can be minimized.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] refer to Figure 1 , Figure 1 A schematic structural diagram of a display panel provided in an embodiment of the present invention includes a color filter substrate 11 and an array substrate 12 that are arranged opposite to each other, and a liquid crystal layer 13 located between the color filter substrate 11 and the array substrate 12 .

[0035] The array substrate 12 includes a driving circuit layer 14 , and the driving circuit layer 14 includes a thin film transistor 15 .

[0036] Specifically, Figure 1 The array substrate 12 shown includes a base substrate 16, a buffer layer 17 located on one side of the base substrate 16, and a driving circuit layer 14 located on the side of the buffer layer 17 away from the base substrate 16, the driving circuit layer 14 includes but is not limited to a plurality of thin film transistors 15, a passivation layer 143 and a planarization layer 144, wherein the thin film transistor 15 includes an active layer 151, a gate 152, a source 153, and a drain 154, the driving circuit layer 14 also includes a gate insulation layer 141 arranged between the active layer 151 and the gate 152, and an interlayer insulation layer 142 arranged between the gate 152 and the source 153 and the drain 154, the passivation layer 143 is arranged on the side of the source 153 and the drain 154 away from the interlayer insulation layer 142, and the planarization layer 144 is arranged on the side of the passivation layer 143 away from the interlayer insulation layer 142. It should be noted that the source 153 and the drain 154 are located on the same layer.

[0037] It should be noted that Figure 1 In the description, only one thin film transistor 15 is taken as an example.

[0038] Optionally, the buffer layer 17 includes but is not limited to an inorganic material layer or an organic material layer, wherein the material of the inorganic material layer includes but is not limited to silicon oxide, silicon nitride, silicon oxynitride, aluminum oxide or aluminum nitride, etc., and the material of the organic material layer includes but is not limited to acrylic or PI, etc. In the embodiment of the present invention, the buffer layer is illustrated by taking the organic material layer as an example.

[0039] refer to Figure 2 , Figure 2 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention is shown in FIG. Figure 2 The array substrate 12 further includes a pixel circuit layer 18 located on the side of the driving circuit layer 14 facing the color filter substrate 11 . The pixel circuit layer 18 includes gate lines Scan and data lines Data.

[0040] Specifically, the gate lines Scan and the data lines Data intersect to form a plurality of pixel regions 19 , and the plurality of pixel regions 19 are arranged in an array. In the embodiment of the present invention, the vertical intersection of the gate lines Scan and the data lines Data is taken as an example for description.

[0041] refer to Figure 3 , Figure 3 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention, combined with Figure 1 and Figure 3 It can be seen that the color filter substrate 11 includes a color filter base 111 and a plurality of color resists 112 located on the side of the color filter base 111 facing the array substrate 12. The color resists 112 extend along a first direction X and are arranged in sequence along a second direction Y. That is, in the embodiment of the present invention, the color resists 112 are strip-shaped color resists as an example for description. The first direction X can be a row direction or a column direction of an array arrangement of a plurality of pixel regions 19. In the following embodiments of the present invention, the first direction X is taken as an example of a column direction of an array arrangement of a plurality of pixel regions 19.

[0042] like Figure 3 As shown, the color resist 112 includes a first color resist 112a and a second color resist 112b, the first color resist 112a corresponds to the first pixel area, the second color resist 112b corresponds to the second pixel area, and the light transmittance of the first color resist 112a is less than the light transmittance of the second color resist 112b; the first direction X intersects with the second direction Y, and are respectively parallel to the plane where the color filter substrate 11 is located; in the embodiment of the present invention, the first direction X and the second direction Y are perpendicular to each other for explanation.

[0043] Further, such as Figure 3 The display panel shown further includes a heating line L1 , which is stacked with at least a portion of the first color resist 112 a along a third direction, and extends along a first direction X; the third direction is perpendicular to the plane where the array substrate 12 is located.

[0044] Specifically, in the embodiment of the present invention, since the light transmittance of the first color resist 112a is less than the light transmittance of the second color resist 112b, it can be seen that the light transmittance of the first pixel area is less than the light transmittance of the second pixel area. Therefore, in the embodiment of the present invention, the heating line L1 is only set in part of the first pixel area, so that the heating line L1 and the first color resist 112a are stacked along the third direction, and the heating line L1 is not set in the second pixel area. Obviously, the light transmittance of the second pixel area is not affected by the heating line L1, and the first pixel area with lower light transmittance has its own lower light transmittance. Therefore, even if the heating line L1 is set accordingly, the degree of influence of the heating line L1 on the light transmittance of the first pixel area will be relatively small. Therefore, the setting of the heating line L1 can achieve the heating of the liquid crystal, and can also minimize the influence of the heating line L1 on the display effect of the display panel.

[0045] For further reference, Figure 4 , Figure 4 A schematic structural diagram of another display panel provided by an embodiment of the present invention, wherein the pixel region further includes a third pixel region.

[0046] The color resist 112 further includes a third color resist 112c corresponding to a third pixel region. The light transmittance of the first color resist 112a is smaller than that of the second color resist 112b and smaller than that of the third color resist 112c.

[0047] The first color resist 112a is a blue color resist, the second color resist 112b is a red color resist, and the third color resist 112c is a green color resist.

[0048] For example, when the heating line L1 is not set, the light transmittance of the first pixel area is 5%, the light transmittance of the second pixel area is 25%, and the light transmittance of the third pixel area is 70%. The influence of the heating line L1 on the light transmittance of the pixel area is 50%. Then, if the heating line L1 is set in the first pixel area, the light transmittance of the first pixel area will become 2.5%; if the heating line L1 is set in the second pixel area, the light transmittance of the second pixel area will become 12.5%; if the heating line L1 is set in the third pixel area, the light transmittance of the third pixel area will become 35%. Obviously, the difference between the light transmittance effect when the heating line L1 is not set in the third pixel area and the light transmittance effect after the heating line L1 is set is the largest; the difference between the light transmittance effect when the heating line L1 is not set in the second pixel area and the light transmittance effect after the heating line L1 is set is also relatively large; while the difference between the light transmittance effect when the heating line L1 is not set in the first pixel area and the light transmittance efficiency after the heating line L1 is set is relatively low.

[0049] To further illustrate from another perspective, assuming that the light emission of each bulb is the same, there is a clear difference between the effect of 100 bulbs lighting up at the same time and 50 bulbs lighting up at the same time, while the difference between the effect of 4 bulbs lighting up at the same time and 2 bulbs lighting up at the same time is obviously relatively small.

[0050] Therefore, in the embodiment of the present invention, the heating line L1 is only set in correspondence with at least part of the pixel area with the lowest light transmittance, and the heating line L1 is not set in other pixel areas. Obviously, the light transmittance of this part of the pixel area without the heating line L1 is not affected by the heating line L1. The pixel area with the lowest light transmittance has the lowest light transmittance itself. Therefore, even if the heating line L1 is set accordingly, the influence of the heating line L1 on the light transmittance of the pixel area with the lowest light transmittance will be relatively small. Therefore, the setting of the heating line L1 can achieve heating of the liquid crystal and minimize the influence of the heating line L1 on the display effect of the display panel.

[0051] Optionally, in another embodiment of the present invention, refer to Figure 5 , Figure 5 A schematic diagram of the structure of another display panel provided in an embodiment of the present invention, the display panel further includes:

[0052] The first area AA and the second area BB are opposite to each other in the first direction X, and the color resist 112 is located between the first area AA and the second area BB.

[0053] The first area AA and / or the second area BB is provided with a crimping pad 20 , and the heating line L1 is electrically connected to the crimping pad 20 to form a current loop.

[0054] Specifically, in the embodiment of the present invention, the first area AA and the second area BB can be understood as partial border areas of the display panel, and the area where the color resist 112 is located can be understood as the display area of ​​the display panel. By setting a crimping pad 20 in the first area AA and / or the second area BB, the heating line L1 is electrically connected to the crimping pad 20 to form a current loop, and then when current flows through the heating line L1, the heating line L1 generates heat to heat the liquid crystal.

[0055] It should be noted that in Figure 5 In the description, an example is given in which the first area AA and the second area BB are both provided with the compression pad 20 .

[0056] Optionally, in another embodiment of the present invention, refer to Figure 6 , Figure 6 A schematic structural diagram of another display panel provided by an embodiment of the present invention, the display panel further comprises: a flexible circuit board 21, and the flexible circuit board 21 is integrated with a current control module.

[0057] The crimping pad 20 is electrically connected to the flexible circuit board 21 , and the current control module is used to transmit current to the heating line L1 .

[0058] Specifically, in the embodiment of the present invention, based on the characteristics of the flexible circuit board 21, the thicker internal wiring can usually directly output a large current, and the integrated current control module is combined to control the state of current delivery to the heating wiring L1, ensuring that the heating wiring L1 can generate sufficient heat to heat the liquid crystal in the heating state, thereby improving the heating effect.

[0059] Optionally, in another embodiment of the present invention, refer to Figure 7 , Figure 7 The schematic diagram of the structure of another display panel provided by an embodiment of the present invention, the display panel further includes: a driving chip 22 .

[0060] The driving chip 22 is electrically connected to the crimping pad 20 , and the driving chip 22 is used to transmit current to the heating line L1 .

[0061] Specifically, in the embodiment of the present invention, there is no need to set up an additional flexible circuit board. The state of transmitting current to the heating line L1 is directly controlled by the driver chip 22 that controls the working state of the display panel. This method can also ensure that the heating line L1 generates sufficient heat to heat the liquid crystal in the heating state, thereby improving the heating effect. In addition, the flexible circuit board component is omitted, and the spatial layout of the display panel can be optimized, thereby reducing its production cost.

[0062] Optionally, in another embodiment of the present invention, refer to Figure 8 , Figure 8 This is a schematic structural diagram of another display panel provided by an embodiment of the present invention. The first area AA is provided with a first compression pad 20a, and the second area BB is provided with a second compression pad 20b.

[0063] The first end of the heating line L1 extends to the first area AA and is electrically connected to the first crimping pad 20 a , and the second end of the heating line L1 extends to the second area BB and is electrically connected to the second crimping pad 20 b .

[0064] Specifically, in the embodiment of the present invention, crimping pads 20 are provided in both the first area AA and the second area BB. It is only necessary to connect a crimping pad 20 at each end of the heating line L1 to form a current loop. The connection method is simple, and the required crimping pads 20 are distributed in the first area AA and the second area BB on both sides. Therefore, more heating lines L1 and corresponding crimping pads 20 can be provided in a limited space.

[0065] Optionally, in another embodiment of the present invention, refer to Fig. 9 , Fig. 9 This is a schematic structural diagram of another display panel provided by an embodiment of the present invention. The first area AA is further provided with a first connection line M1 , and the first connection line M1 extends along the second direction Y.

[0066] The first ends of at least two heating wires L1 extend to the first area AA and are electrically connected to a first connecting wire M1 .

[0067] The second area BB is provided with a compression pad 20 .

[0068] The second ends of at least two heating traces L1 extend to the second area BB and are electrically connected to one of the crimping pads 20 respectively.

[0069] Specifically, in the embodiment of the present invention, the first ends of the two heating lines L1 are extended to the first area AA and electrically connected to a first connecting line M1 as an example, and the first ends of the two heating lines L1 are extended to the first area AA and electrically connected through a first connecting line M1, and the second ends thereof are respectively electrically connected to a crimping pad 20 in the second area BB, so that a current loop is formed by the two heating lines L1, and the current loop is formed by the two heating lines L1. Figure 8 It can be seen that four crimping pads can be omitted when only one more first connecting wire M1 is provided, and the first connecting wire M1 extends along the second direction Y, which means that the setting of the first connecting wire M1 does not take up too much space, thereby simplifying the design difficulty of the panel while achieving the same function.

[0070] Similarly, reference Fig.10 , Fig.10 A structural schematic diagram of another display panel provided for an embodiment of the present invention may also be that a first connecting line M1 is provided in the second area BB, and the first connecting line M1 also extends along the second direction Y, and the second ends of at least two of the heating lines L1 extend to the second area BB and are electrically connected to one of the first connecting lines M1, and a compression pad 20 is provided in the first area AA, and the first ends of at least two of the heating lines L1 extend to the first area AA and are electrically connected to one of the compression pads 20 respectively.

[0071] Optionally, in another embodiment of the present invention, refer to Fig.11 , Fig.11 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Fig.12 , Fig.12 This is a schematic structural diagram of another display panel provided by an embodiment of the present invention, in which at least two heating lines L1 form a heating unit 21 .

[0072] The first area AA is further provided with a second connection line M2 , and the second connection line M2 extends along the second direction Y.

[0073] Portions of at least two heating units 21 located in the first area AA are electrically connected to a second connection line M2 .

[0074] The second area BB is provided with a third connection line M3 and a compression pad 20 , and the third connection line M3 extends along the second direction Y.

[0075] The second end of the heating line L1 in the heating unit 21 further extends to the second area BB and is electrically connected to one of the third connecting lines M3;

[0076] The second end of any heating line L1 in the heating unit 21 further extends to a side of the third connecting line M3 away from the color resist 112 , and is electrically connected to a crimping pad 20 .

[0077] Specifically, in the embodiment of the present invention, three heating lines L1 are taken as an example to form a heating unit 21, by electrically connecting the parts of at least two heating units 21 located in the first area AA to a second connecting line M2, and the second end of the heating line L1 in each heating unit 21 also extends to the second area BB, and is electrically connected to the third connecting line M3, and then electrically connected to a crimping pad 20.

[0078] Combination Figure 8 , Fig. 9 and Fig.10 From the structure shown, we can see that Fig.11 and Fig.12 The structure shown can form more current loops through various series-parallel combinations, thereby enabling the heating line L1 to generate sufficient heat to effectively heat the liquid crystal.

[0079] and Fig.11 and Fig.12 This design of the structure shown can also greatly reduce the number of crimping pads 20 while realizing more current loops, and the second connecting line M2 and the third connecting line M3 extend along the second direction Y, which means that the setting of the second connecting line M2 and the third connecting line M3 does not take up too much space, thereby simplifying the design difficulty of the panel while realizing the same function.

[0080] It should be noted that since the first connecting wire M1, the second connecting wire M2 and the third connecting wire M3 are actually prepared at the same time as the heating line L1 and are the same metal wires, the connecting wires can also generate heat in the case of a current loop passage, but the heat generated by the connecting wires cannot effectively heat the liquid crystal, so they are named connecting wires in the embodiments of the present invention.

[0081] It should be further explained that the series-parallel structure formed by the heating line L1 and the connecting line can also be in other forms. Fig. 9 , Fig.10 , Fig.11 and Fig.12 The structure shown is used as an example for explanation.

[0082] Optionally, in another embodiment of the present invention, in the second direction Y, the number of the first color resists 112 a that are not stacked with the heating lines L1 between two adjacent heating lines L1 is greater than or equal to zero.

[0083] Specifically, Figure 8-Figure 12 As shown, the number of first color resists 112a of the heating lines L1 that are not stacked between some two adjacent heating lines L1 is equal to zero, and the number of first color resists 112a of the heating lines L1 that are not stacked between some two adjacent heating lines L1 is greater than zero. That is to say, the spacing between two adjacent heating lines L1 can be one pixel or multiple pixels, and can be equidistant or unequally spaced, and can be adaptively set according to the heating requirements of different areas. For example, more heating lines L1 can be set in areas that need heating more, such as the heating lines L1 in areas away from the backlight can be set more densely.

[0084] Optionally, in another embodiment of the present invention, refer to Fig.13 , Fig.13 This is a schematic structural diagram of another display panel provided by an embodiment of the present invention. The color resist 112 includes first segments and second segments alternately connected in a first direction X, and the extension directions of the first segments and the second segments intersect.

[0085] The heating line L1 includes a third segment and a fourth segment alternately connected in the first direction X, and the extension directions of the third segment and the fourth segment intersect.

[0086] In the third direction, the third segment is stacked with the first segment, and the fourth segment is stacked with the second segment.

[0087] The angle between the first segment and the second segment is a first angle, the angle between the third segment and the fourth segment is a second angle, and the first angle is the same as the second angle.

[0088] Specifically, in the embodiment of the present invention, when the pixel in the display panel is a dual-domain pixel or a pseudo dual-domain pixel, the heating line L1 thereof also needs to be designed to be zigzag to match the pixel.

[0089] It should be further explained that in order to ensure that the heating lines L1 have the same appearance in the display area, the parameters such as width and shape of each heating line L1 can be set to the same. For the convenience of design, the shape, width and length of the connecting line can also be set to the same.

[0090] Optionally, in another embodiment of the present invention, refer to Fig.14 , Fig.14 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Fig.15 , Fig.15 The schematic diagram of the structure of another display panel provided by an embodiment of the present invention is that the heating line L1 is located on the side of the driving circuit layer 14 away from the color filter substrate 11 ; or, the heating line L1 is located on the side of the pixel circuit layer 18 facing the color filter substrate 11 .

[0091] Specifically, in the embodiments of the present invention, Fig.14 The heating line L1 is located on the side of the driving circuit layer 14 away from the color filter substrate 11. Fig.15 The heating line L1 shown is located on the side of the pixel circuit layer 18 facing the color film substrate 11. That is to say, no matter where the heating line L1 is set, it is best to ensure that the setting of the heating line L1 will not cause too much impact on other structures of the display panel, especially to avoid parasitic capacitance with other metal film layers as much as possible.

[0092] It should be noted that Fig.14 and Fig.15 The heating wiring L1 is set corresponding to the light-shielding color resistance BM in the color film substrate 11; if the heating wiring L1 is a transparent heating wiring, for example, the heating wiring L1 is an ITO heating wiring, there is no need to set BM shielding in the blue pixel. This is because there is an extra ITO film layer at the blue pixel, which causes the light transmittance of the blue pixel to decrease; if the heating wiring L1 is a metal wiring, a BM needs to be set at the corresponding position of the heating wiring in the blue pixel. This is because the light transmittance of the blue pixel is reduced due to the reduction of the light-transmitting area at the blue pixel.

[0093] Optionally, based on all the above embodiments of the present invention, another embodiment of the present invention further provides a display device, referring to Fig.16 , Fig.16 A schematic structural diagram of a display device provided by an embodiment of the present invention.
