Description

Technical Field

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

[0002] Liquid crystal displays (LCDs) are widely used in various fields due to their advantages such as light weight, low power consumption, and no radiation.

[0003] In the production of thin-film transistor liquid crystal displays (TFT-LCDs), an alignment liquid must first be applied to the array substrate or color filter substrate to form an alignment film for aligning the liquid crystal. Next, the liquid crystal must be dripped in, and frame glue is applied. The two substrates are then aligned and the frame glue is cured. The frame glue bonds the array substrate and color filter substrate together and protects the liquid between them from external air and water. The alignment liquid coating area is slightly smaller than the area surrounded by the frame glue, and the frame glue is located outside the alignment liquid coating area.

[0004] Since water vapor still intrudes from the air at the contact portion between the frame glue and the array substrate and the contact portion between the frame glue and the color filter substrate, the reliability and manufacturing yield of the display panel are low. Summary of the Invention

[0045] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner.In the following description, many specific details are provided so as to provide a full understanding of the embodiments of the present application. However, it will be appreciated by those skilled in the art that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps etc. can be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0046] Example 1

[0047] See Figure 1 As shown, embodiment 1 of the present application provides a display panel 100, which may be a liquid crystal display panel 100. The display panel 100 may include a first substrate 110, a second substrate 120 and a liquid crystal layer 130. The first substrate 110 and the second substrate 120 are arranged in a box, and the liquid crystal layer 130 is arranged between the first substrate 110 and the second substrate 120.

[0048] It is understood that the liquid crystal layer 130 includes a plurality of liquid crystal molecules spaced apart from each other, and when power is supplied to the first substrate 110 and the second substrate 120 , the liquid crystal layer 130 can control the deflection angles of the liquid crystal molecules.

[0049] In addition, the first substrate 110 can be one of an array substrate and a color filter substrate, and the second substrate 120 can be the other of the array substrate and the color filter substrate. For example, the first substrate 110 is an array substrate, and the second substrate 120 is a color filter substrate.

[0050] Among them, the array substrate includes a base substrate and a thin film transistor (not shown in the figure) and a pixel electrode (not shown in the figure) arranged on the base substrate. The thin film transistor may include a gate, an active layer and a first electrode and a second electrode arranged in the same layer. A gate insulation layer may be provided between the gate and the active layer to insulate the gate and the active layer from each other; and the first electrode and the second electrode may be respectively connected to the source and drain doping regions of the active layer. Specifically, the corresponding connection relationship between the first electrode and the second electrode and the source and drain doping regions of the active layer can be determined according to whether the thin film transistor is N-type or P-type, which will not be described in detail here.

[0051] For example, the thin film transistor of the embodiment of the present application may be a bottom-gate type, that is, the gate may be first formed on the base substrate; then, a gate insulating layer is formed on the base substrate, and this gate insulating layer covers the gate; then, an active layer is formed on the side of the gate insulating layer away from the base substrate, that is, the active layer is located on the side of the gate away from the base substrate, and this active layer overlaps with the orthographic projection of the gate on the base substrate. For example, the orthographic projection of the active layer on the base substrate may be located within the orthographic projection of the gate on the base substrate; the first pole and the second pole may be formed after the active layer is formed, and at least a portion of the first pole may overlap on one doped region of the source and drain doped regions of the active layer; at least a portion of the second pole may overlap on another doped region of the source and drain doped regions of the active layer.

[0052] The second substrate 120 may include a glass substrate and a color resist layer, a BM layer, a common electrode plate, an alignment film, etc. formed on the glass substrate, which will not be described in detail herein.

[0053] It should be noted that the first substrate 110 and the second substrate 120 include a display area and a non-display area, which is arranged around the display area. The non-display area includes a wiring area 140 and a non-wiring area 150. The non-wiring area 150 is located on the side of the wiring area 140 away from the liquid crystal layer 130. The wiring area 140 is used to set up driving wiring on the first substrate 110 and the second substrate 120. For example, the wiring area 140 is provided with a gate driver less (GDL) for transmitting signals to the gate on the array substrate side to turn on or off the thin film transistor.

[0054] Please continue to see Figure 1 As shown, Figure 1A structural schematic diagram of the condensation member 180 provided in an embodiment of the present application is shown, which is arranged between the first frame glue 160 and the second frame glue 170; in order to prevent external water vapor from invading the display panel 100 and corroding the wiring in the wiring area 140, the present application also includes a first frame glue 160, a second frame glue 170 and a condensation member 180, so as to reduce the problem of external water vapor invading the display panel 100, to ensure the dryness in the wiring area 140, to ensure the normal transmission of electrical signals of the circuit, and thus to ensure the display effect of the display panel 100, and to improve the reliability and manufacturing yield of the display panel 100.

[0055] Please continue to see Figure 1 As shown, the first sealant 160 and the second sealant 170 are both disposed between the first substrate 110 and the second substrate 120. The first sealant 160 and the second sealant 170 are spaced apart from each other, and the first sealant 160 is disposed on the side of the second sealant 170 closer to the liquid crystal layer 130; that is, the first sealant 160 is closer to the interior than the second sealant 170. The double-layer sealant arrangement can extend the path for external moisture to enter the wiring area 140, partially isolating the wiring area 140 from moisture intrusion, thereby ensuring the dryness of the wiring area 140.

[0056] It is understandable that due to the different material properties of the contact surfaces between the first and second frame glues 160, 170 and the first and second substrates 110, 120, it is inevitable that adhesion "holes" are formed at the contact surfaces between the first and second frame glues 160, 170 and the first and second substrates 110, 120. During long-term use, water vapor may enter the display panel 100 along the "holes", causing corrosion and damage to the circuits in the display panel 100, resulting in the display panel 100 being unable to work normally.

[0057] It should be noted that the first sealant 160 and the second sealant 170 are both located in the non-wiring area 150 , and are used to extend the path for water vapor to penetrate and reduce the water vapor content invading the wiring area 140 .

[0058] Also, see Figure 1 or Figure 2As shown, since the first sealant 160 and the second sealant 170 are spaced apart from each other and are both connected to the first substrate 110 and the second substrate 120, a condensation zone 190 is formed between the first substrate 110, the second substrate 120, the first sealant 160, and the second sealant 170. A condensation member 180 is provided in the condensation zone 190. When external water vapor passes through the second sealant 170, the water vapor enters the condensation zone 190. The condensation member 180 in the condensation zone 190 condenses the water vapor that has entered the condensation zone 190, preventing the external water vapor from further entering the wiring area 140. This ensures the dryness of the wiring area 140, ensures the normal transmission of electrical signals by the circuit, and thus ensures the display effect of the display panel 100, thereby improving the reliability and manufacturing yield of the display panel 100.

[0059] It is understandable that the condensing element 180 may be an air-cooled condenser or a device formed of an electro-cooling material; of course, it is not limited thereto, as long as the device can condense water vapor.

[0060] In the embodiment of the present application, the condensation member 180 is arranged around the inner wall of the condensation area 190 to ensure that most of the external water vapor can be condensed in the condensation area 190 to prevent the external water vapor from penetrating into the wiring area 140.

[0061] In some embodiments, this condensation element 180 can adopt multiple groups of condensation groups spaced apart from each other, each condensation group includes multiple condensation elements 180, and each condensation element 180 includes a first drive plate 181, a second drive plate 182 and a condensation block 183. Through the action of each group of first drive plate 181, second drive plate 182 and condensation block 183, external water vapor is prevented from flowing into the routing area 140, thereby ensuring the drying effect of the lines in the routing area 140.

[0062] In the embodiment of the present application, the condensation element 180 comprises a device formed of an electrorefrigeration material. The condensation element 180 is an integral unit, comprising a first drive plate 181, a second drive plate 182, and a condensation block 183. The first drive plate 181 and the second drive plate 182 are respectively disposed on the first substrate 110 and the second substrate 120, i.e., the first drive plate 181 is located on the first substrate 110, and the second drive plate 182 is located on the second substrate 120, with the first drive plate 181 and the second drive plate 182 being disposed opposite each other. The condensation block 183 is disposed around the wall surface of the condensation area 190. The condensation block 183 can be made of a condensation material, which can be attached to the wall surface of the condensation area 190 by spraying. The first drive plate 181 and the second drive plate 182 are connected to different voltages, which can control the condensation block 183 to operate continuously. When water vapor enters the condensation area 190, the condensation block 183 absorbs heat and accumulates water on the surface of the condensation block 183.

[0063] It should be noted that the first and second drive plates 181, 182 can utilize a moisture-sensitive thin film electrode coating, which can be formed from materials such as aluminum oxide, polyacrylic acid, or a carbon-based material. The condensation block 183 can be made of materials such as bismuth telluride and its alloys, lead titanium oxide, ferroelectric polymers, ferroelectric ceramics, and ferroelectric oxides. Different voltages can be connected to the first and second drive plates 181, 182 to control the operating state of the condensation block 183.

[0064] Furthermore, the first and second driver boards 181 and 182 can be connected to circuits in the wiring area 140 to supply different voltages. For example, the first driver board 181 is connected to the high-level signal (VGH) of the gate driver less (GDL), and the second driver board 182 is connected to the ground line GND. By supplying different voltages between the first and second driver boards 181 and 182, the condensation state of the electro-cooling material, i.e., the condensation block 183, can be controlled.

[0065] When the first driving board 181 and the second driving board 182 drive and control the condensing block 183 to be in a condensing state, the condensing block 183 can absorb the heat of the external water vapor, so that the water vapor condenses in the condensation area 190. The water vapor will condense and adhere to the surface of the condensing block 183, and cannot penetrate into the wiring area 140 through the first frame glue 160, thereby ensuring the dryness of the wiring area 140 and the stability of the line transmission in the wiring area 140, thereby ensuring the display effect of the display panel 100 and improving the reliability and manufacturing yield of the display panel 100.

[0066] It is worth mentioning that since the condensation block 183 is attached to the inner wall of the condensation area 190 by spraying or other methods, the central area of ​​the condensation block 183 is a hollow area. When water vapor passes through the second sealant 170 and contacts the condensation block 183, the water vapor tends to condense in this hollow area to form water droplets, and will not pass through the first sealant 160 and penetrate into the wiring area 140, thus ensuring the dryness of the wiring area 140. In other words, the condensation block 183 can block water vapor in the hollow area, preventing water vapor from penetrating from all sides.

[0067] For an example, see Figure 1As shown, the interior of the condensation block 183 is provided with an annular chamber 184. The interface of the annular chamber 184 in the thickness direction of the first substrate 110 is a waist-shaped structure, which refers to a closed figure formed by bisecting a circle through the center of the circle into two semicircular arcs, which are translated in opposite directions and connected by two equal-length parallel lines at the endpoints of the two semicircular arcs. The two semicircles of the waist-shaped structure are located on either side of the first substrate 110 and the second substrate 120, respectively. The two parallel lines are parallel to the first and second sealants 160 and 170, that is, the waist-shaped structure is perpendicularly arranged between the first and second substrates 110 and 120.

[0068] It can be understood that after the water vapor passes through the condensation effect of the condensation block 183, water droplets are formed on the inner wall of the annular chamber 184. The water droplets tend to flow downward on the inner wall of the annular chamber 184 and temporarily remain at the bottom of the annular chamber 184 to facilitate the collection and discharge of the water droplets.

[0069] Please note that, see Figure 4 As shown, the cross section of the annular chamber 184 in the thickness direction of the first substrate 110 may also be a trapezoidal structure.

[0070] For example, this annular chamber 184 includes a first inner wall, a second inner wall, a third inner wall and a fourth inner wall connected in sequence, the first inner wall is arranged opposite to the third inner wall, the second inner wall is arranged opposite to the fourth inner wall, the opposite ends of the first inner wall are respectively connected to the second inner wall and the fourth inner wall, and the opposite ends of the third inner wall are also connected to the second inner wall and the fourth inner wall, that is: the opposite end of the first inner wall and the third inner wall is connected through the second inner wall, and the other opposite end of the first inner wall and the third inner wall is connected through the fourth inner wall. The first inner wall and the third inner wall respectively form the upper and lower bases of the trapezoidal structure, while the second inner wall and the fourth inner wall respectively form the two waists of the trapezoidal structure. The area of ​​the first inner wall is smaller than that of the third inner wall. The first inner wall is located on the side of the second inner wall close to the first sealant 160, that is, the first inner wall is located on the side close to the wiring area 140, and the third inner wall is located on the side close to the non-wiring area 150. The second inner wall and the fourth inner wall both form an obtuse angle with the first inner wall, while the second inner wall and the fourth inner wall both form an acute angle with the third inner wall. This trapezoidal structure can collect water droplets on the wall surface of the annular chamber 184 to the bottom of the annular chamber 184, facilitating the collection and discharge of the water droplets.

[0071] In some embodiments, the trapezoidal structure is an isosceles trapezoid, ie, the second inner wall and the fourth inner wall have the same length.

[0072] In the embodiments of this application, Figure 2As shown, the display panel 100 has a sky side and a ground side that are relatively set, as well as a left side and a right side that are relatively set. The sky side can be understood as the side of the display panel away from the ground when in use, and the ground side can be understood as the side of the display panel close to the ground when in use.

[0073] The opposite ends of the sky side are connected to the opposite ends of the ground side via the left and right sides, respectively. At least one of the connection between the ground side and the left and right sides and the connection between the sky side and the left and right sides is provided with a collection chamber 1100 for collecting liquid condensed by the condensation block. That is, the connection between the ground side and the left and right sides may form the collection chamber 1100, while the connection between the sky side and the left and right sides may not form the collection chamber 1100; or the connection between the sky side and the left and right sides may form the collection chamber 1100, while the connection between the ground side and the left and right sides may not form the collection chamber 1100; or the connection between the sky side and the left and right sides may form the collection chamber 1100, and the connection between the ground side and the left and right sides may also form the collection chamber 1100.

[0074] That is, the collection chambers 1100 may be provided at the two corners at the bottom of the display panel 100 , at the two corners at the top of the display panel 100 , or at the four corners of the display panel 100 .

[0075] Also, see Figure 5 and Figure 6 As shown, the display panel 100 further includes a heating element 1110, which is disposed in the collection chamber 1100, with the opposite ends of the heating element 1110 respectively approaching the first driving plate 181 and the second driving plate 182; that is, the heating element 1110 is disposed adjacent to the first driving plate 181 and the second driving plate 182. When the amount of water collected in the collection chamber 1100 reaches a preset condition value, since the water droplets are conductive, when the water droplets are formed between the heating element 1110 and the first driving plate 181 and between the heating element 1110 and the second driving plate 182, the water droplets are used to connect one end of the heating element 1110 to the first driving plate 181 and the other end of the heating element 1110 to the second driving plate 182, and the first driving plate 181 and the second driving plate 182 are used to heat the heating element 1110. The heating element 1110 generates heat in this collection chamber 1100, so that the temperature of the collection chamber 1100 is higher than the external temperature, and the water vapor is discharged outward, further preventing the water vapor from penetrating into the wiring area 140, ensuring the normal operation of the wiring area 140, and then ensuring the display effect of the display panel 100, and improving the reliability of the display panel 100.

[0076] It should be understood that when the heating element 1110 is heated, the first frame glue 160 and the second frame glue 170 will expand thermally, so that the first frame glue 160 and the second frame glue 170 seal the gap between them and the first substrate 110 and the second substrate 120, further preventing water vapor from penetrating into the routing area 140.

[0077] It is worth mentioning that the heating element 1110 can adopt a heating structure such as a resistance wire.

[0078] For example, Figure 2 As shown, a collection chamber 1100 is provided at the junction of the ground side with the left and right sides. In the thickness direction of the display panel 100, there is a height difference between the top side and the ground side. The top side is closer to one side of the backlight module 200 than the ground side, that is, the top side is lower and the ground side is higher. Thus, when the display panel 100 is placed vertically, water droplets can slide down the slope between the top side and the ground side into the collection chamber 1100, making it easier to collect the water droplets in the collection chamber 1100.

[0079] In the embodiments of this application, Figure 2 As shown, the display panel is further provided with a capillary drainage hole 1120, which is circular, square, or triangular in shape. The drainage hole 1120 is provided on the side of the display panel and is connected to the collection chamber 1100. The drainage hole 1120 can drain water droplets from the collection chamber 1100.

[0080] It should be noted that the drain hole 1120 may be opened only when the amount of water in the collection chamber 1100 reaches a preset value, to ensure that the heating element 1110 can be electrically connected to the first driving plate 181 and the second driving plate 182 under the action of water droplets.

[0081] In addition, the drain hole 1120 can drain water droplets from the collection chamber 1100 during the heating process of the heating element 1110 , thereby preventing the heating element 1110 from generating a large amount of water vapor that flows back into the condensation area 190 .

[0082] It is understandable that under the influence of high temperature, the water droplets in the collection chamber 1100 gradually decrease, so that there is no water drop conductor connection between the first drive plate 181 and the second drive plate 182 and the heating element 1110, and the heating is completed. The first drive plate 181 and the second drive plate 182 receive different voltage signals again to control the condensation block 183 to continue the condensation work. When the water vapor in the collection chamber 1100 reaches a certain humidity, the heating element 1110 is controlled to perform heating treatment. This reciprocating process can continuously block external water vapor, prevent external water vapor from penetrating into the wiring area 140, and prevent the lines in the wiring area 140 from being corroded, thereby ensuring the display effect of the display panel 100 and improving the reliability and production yield of the display panel 100.

[0083] In addition, if Figure 2 As shown, to prevent water vapor from flowing back into condensation zone 190 during heating by heating element 1110, a detour 1130 is provided at the junction of the ground side with the left and right sides. This detour 1130 can be configured in a serpentine shape, a chamfered shape, or a curved corner. During the heating process, water vapor condenses at detour 1130 and flows back into collection chamber 1100.

[0084] For example, Figure 2 As shown, the winding portion 1130 is arranged in a serpentine shape, and the winding portion 1130 is arranged to protrude toward the outside of the display area of ​​the display panel 1100, so that the winding portion 1130 is arranged away from the display area of ​​the display panel 100, extending the path for water vapor to enter the wiring area 140, and ensuring a dry environment in the wiring area 140.

[0085] In addition, in order to prevent heat from the connection between the ground side and the left and right sides from flowing to the condensation area, an insulation layer is provided on the inner wall of the detour portion 1130 to prevent water droplets in the condensation area 190 from evaporating and seeping into the routing area 140.

[0086] Drainage hole 1120 Drainage hole 1120 This application solution uses the first driving plate 181 and the second driving plate 182 to drive the condensation block 183 to perform condensation between the two pieces of frame glue, preventing water vapor from penetrating into the wiring area 140 through the first frame glue 160, thereby ensuring the drying effect of the wiring area 140. In addition, a heating element 1110 is provided in the collection chamber 1100. When the water droplets in the collection chamber 1100 reach a preset condition, the first driving plate 181 and the second driving plate 182 are respectively connected to the opposite ends of the heating element 1110. The first driving plate 181 and the second driving plate 182 provide current to the heating element 1110, and the heating element 1110 releases heat in the collection chamber 1100, so that the temperature in the collection chamber 1100 increases, so as to facilitate the discharge of water vapor in the collection chamber 1100; and during the heating process, the first frame glue 160 and the second frame glue 170 will also be heated and expanded, further reducing the gap between the first frame glue 160 / the second frame glue 170 and the first substrate 110 and the second substrate 120, further preventing water vapor from penetrating into the routing area 140. Moreover, this process can be used repeatedly to continuously prevent external moisture from entering the wiring area 140, ensure the dryness of the wiring area 140, avoid corrosion of the lines in the wiring area 140, ensure the display effect of the display panel 100, and improve the reliability and manufacturing yield of the display panel 100.
