Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The display panel generally comprises a Color Filter (CF) substrate, an array substrate, and a liquid crystal layer disposed between the two substrates, and has a working principle of placing liquid crystal molecules between two parallel glass substrates, wherein a plurality of vertical and horizontal fine wires are disposed between the two glass substrates, and the liquid crystal molecules are controlled to change direction by power-on or power-off to refract light from the backlight module to generate a picture. The array substrate is provided with a Thin Film Transistor (TFT) array substrate for driving liquid crystal to rotate and controlling the display of each pixel, and the color film substrate is provided with an RGB color filter layer for forming the color of each pixel.

However, in the display panel, because the array substrate and the color film substrate need to be connected by means of glue or the like, static electricity on the color film substrate cannot be led out through the array substrate, the static electricity which cannot be dissipated can affect a working display module, and the problems of signal interference, display jitter, screen splash and the like occur, so that the display panel cannot work normally due to the static electricity interference.

According to the embodiment of the application, the conductive particles are introduced into the optical cement, so that the optical cement has strong conductive capacity, then the optical cement and the color film substrate are connected by using the conductive silver paste, static electricity on the color film substrate is adsorbed onto the optical cement by using the conductive capacity of the optical cement, and then the static electricity is led out of the optical cement through the conductive silver paste. By the method, static electricity on the color film substrate is led out through the optical adhesive and the silver paste, so that the leading-out speed of the static electricity on the color film substrate is higher, the efficiency is higher, and the display panel which normally works cannot be subjected to static interference. And the conductive particles are introduced into the optical adhesive, so that the conductive performance is better than that of a conductive polarizer, static electricity on the color film substrate is easier to dissipate, and the problem that the static electricity on the color film substrate cannot be led out to dissipate is solved. The display panel provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a first structural schematic diagram of a display panel according to an embodiment of the present disclosure. The display panel 10 includes a cover plate 101, an optical adhesive 102, an upper polarizer 103, a color filter substrate 104, an array substrate 105, a lower polarizer 106, and a conductive silver paste 107.

The cover plate 101 is disposed on the optical adhesive 102, the upper polarizer 103 is disposed on a side of the optical adhesive 102 away from the cover plate 101, the color film substrate 104 is disposed on a side of the upper polarizer 103 away from the optical adhesive 102, and the array substrate 105 is disposed on a side of the color film substrate 104 away from the optical adhesive 102.

The array substrate 105 and the color film substrate 104 are connected through glue and the like, the cover plate 101 and the upper polarizer 103 are connected through the optical adhesive 102, and the conductive silver paste 107 extends to the side surface of the array substrate 105 of the color film substrate 104 along the side surface of the optical adhesive 102.

The optical adhesive 102 is disposed between the upper polarizer 103 and the cover plate 101, and conductive particles 1021 are added in the optical adhesive 102. The conductive particles 1021 may be a metal conductive material, and the metal conductive material includes one or more of platinum, palladium, gold, silver, copper, iron, cobalt, nickel, tin, and aluminum, or an alloy thereof. The conductive particles 1021 can be a pure metal, or a combination of metals, or an alloy doped with a non-metallic material, such as those described above. One end of the optical adhesive 102 is connected to the conductive silver paste 107, and the conductive particles 1021 in the optical adhesive 102 are connected to the conductive silver paste 107, so that the static electricity on the surface of the color filter substrate 104 is easily absorbed, and the static electricity on the color filter substrate 104 is led out through the optical adhesive 102 and the conductive silver paste 107. In the related art, the conductive polarizer forms a conductive path using electron migration of a large pi bond in a conjugated system. However, when a customer pursues an extremely thin electronic product, the width requirement of the lower frame of the liquid crystal display module is also relatively limited, which results in a limited number of large pi-bond electrons in the conductive polarizer, and thus the conductive effect of introducing static electricity on the color filter substrate 104 into the grounded conductive channel is not good. Under the condition of ensuring a narrow frame, in the embodiment, the conductive particles 1021 are introduced into the optical adhesive 102, because the thickness of the optical adhesive 102 is larger than the thickness of the occupied space of the large pi-bond electrons in the conjugated system of the conductive polarizer, the conductive particles 1021 of the optical adhesive 102 become more relatively, so that the conductive capability becomes stronger, and further the conductive effect of introducing static electricity on the color film substrate 104 into the grounded conductive channel is improved. In addition, the conductive particles 1021 can be easily added into the optical cement 102, and the process is simple.

The optical adhesive 102 has a first side edge and a second side edge, which are opposite to each other and are respectively located at two opposite sides of the display panel 10. It should be noted that the projection area of the optical adhesive 102 on the array substrate 105 and the projection area of the upper polarizer 103 on the array substrate 105 may be the same or different.

Specifically, with reference to fig. 2 and fig. 3, fig. 2 is a second schematic structural diagram of the display panel provided in the embodiment of the present application, and fig. 3 is a schematic structural diagram of a portion of the display panel shown in fig. 2. When the projection area of the optical adhesive 102 on the array substrate 105 is the same as the projection area of the upper polarizer 103 on the array substrate 105, the conductive silver paste 107 may extend from the side of the optical adhesive 102 to the array substrate 105. The conductive silver paste 107 may be thickly coated, so that the highest surface of the conductive silver paste 107 may be flush with the outer surface of the optical adhesive 102 away from the lower polarization plate 106, thereby increasing the conductive effect of the conductive channel for introducing static electricity on the color filter substrate 104 into the ground.

Referring to fig. 4, fig. 4 is a schematic view illustrating a third structure of a display panel according to an embodiment of the present disclosure. When the vertical projection of the optical adhesive 102 on the array substrate 105 falls within the vertical projection range of the upper polarizer 103 on the array substrate 105, i.e., the projection area of the optical adhesive 102 on the array substrate 105 is smaller than the projection area of the upper polarizer 103 on the array substrate 105, a second step is formed between the end of the optical adhesive 102 and the upper polarizer 103. The formed second step is used for bearing conductive silver paste 107, the conductive silver paste 107 extends from the outer surface of the optical adhesive 102 away from the upper polarizer 103 to the array substrate 105, and static electricity on the color film substrate 104 is conducted and connected to the array substrate 105 through the conductive silver paste 107. Moreover, through the second step, the conductive silver paste 107 can be in full contact with the end of the optical adhesive 102 and in contact with the inner surface of the upper polarizer 103 close to the cover plate 101, so that the contact area between the conductive silver paste 107 and the upper polarizer 103 and the optical adhesive 102 is increased, and the conductive effect of a conductive channel for introducing static electricity on the color film substrate 104 into the ground becomes better.

Referring to fig. 5, fig. 6 and fig. 7, fig. 5 is a fourth structural schematic diagram of a display panel according to an embodiment of the present application, fig. 6 is a first structural schematic diagram of adding silver paste to the display panel shown in fig. 5, and fig. 7 is a second structural schematic diagram of adding silver paste to the display panel shown in fig. 5. When the vertical projection of the optical adhesive 102 on the array substrate 105 falls outside the vertical projection range of the upper polarizer 103 on the array substrate 105, and when the projection area of the optical adhesive 102 on the array substrate 105 is larger than the projection area of the upper polarizer 103 on the array substrate 105, a receiving groove 108 is formed between the end of the color film substrate 104, the edge of the upper polarizer 103 and the end of the optical adhesive 102, the receiving groove 108 is used for containing conductive silver paste 107, the conductive silver paste 107 can be paved on the whole receiving groove 108, the contact area between the conductive silver paste 107 and the optical adhesive 102 is increased, and thicker conductive silver paste 107 can be coated, so that the conductive effect of a conductive channel for introducing static electricity on the color film substrate 104 into the ground is better. It can be understood that after the conductive silver paste 107 is spread over the entire receiving groove 108, it is fully contacted with the edge of the optical adhesive 102, and the conductive silver paste 107 wraps the entire side edge of the optical adhesive 102. This makes the contact area between the conductive silver paste 107 and the optical adhesive 102 larger, so that the conductive effect is better.

Referring to fig. 8, fig. 8 is a top view of a display panel according to an embodiment of the present disclosure. The display panel 10 includes a display area 11 and a non-display area located at the periphery of the display area 11, the display area 11 having a plurality of pixels for displaying an image. The conductive silver paste 107 in the display panel includes a first conductive silver paste 1071 and a second conductive silver paste 1072, and the first conductive silver paste 1071 and the second conductive silver paste 1072 are arranged at intervals and are respectively arranged on two opposite sides of the display panel 10. The distance between the first conductive silver paste 1071 and the second conductive silver paste 1072 is variable and may be arbitrary.

The first conductive silver paste 1071 is connected to the first side edge of the optical adhesive 102, the second conductive silver paste 1072 is connected to the second side edge of the optical adhesive 102, the first conductive silver paste 1071 extends onto the array substrate 105 along the first side edge of the optical adhesive 102, and the second conductive silver paste 1072 extends onto the array substrate 105 along the second side edge of the optical adhesive 102. Specifically, a portion of the first conductive silver paste 1071 contacts a portion of the optical paste 102, and a portion of the first conductive silver paste 1071 contacts a portion of the end portion of the color filter substrate 104. A portion of the second conductive silver paste 1072 contacts a portion of the optical paste 102, and a portion of the second conductive silver paste 1072 contacts a portion of the end portion of the color filter substrate 104. It should be noted that a portion of the first conductive silver paste 1071 may be tangent to a portion of the optical glue 102, or a portion of the first conductive silver paste 1071 may completely wrap the optical glue 102. A portion of the first conductive silver paste 1071 may be tangent to a portion of the end of the color filter substrate 104, or a portion of the first conductive silver paste 1071 may completely wrap the color filter substrate 104. It is only necessary to ensure that the first conductive silver paste 1071 is connected to the optical adhesive 102 and the color filter substrate 104 and that the second conductive silver paste 1072 is connected to the optical adhesive 102 and the color filter substrate 104.

A part of the first conductive silver paste 1071 is further connected to the upper polarizer 103 and the array substrate 105, and the first conductive silver paste 1071 is sequentially connected to the color filter substrate 104, the upper polarizer 103, the optical adhesive 102, and the array substrate 105, so that static electricity on one side of the color filter substrate 104 is led out through the path. A portion of the second conductive silver paste 1072 also connects the upper polarizer 103 and the array substrate 105. The second conductive silver paste 1072 is sequentially connected to the color filter substrate 104, the upper polarizer 103, the optical adhesive 102, and the array substrate 105, so that static electricity on the other side of the color filter substrate 104 is led out through the path. The static electricity on the color film substrate 104 is conducted and dissipated through the channel conducted by the first conductive silver paste 1071 and the channel conducted by the second conductive silver paste 1072.

The shape of the first conductive silver paste 1071 and the shape of the second conductive silver paste 1072 may be dot-shaped structures, and the shape of the cross section thereof may be any shape, such as a circle, a triangle, a rectangle, or any irregular shape. The shape of the first conductive silver paste 1071 and the shape of the second conductive silver paste 1072 may or may not be the same. The first conductive silver paste 1071 in a dotted structure and the second conductive silver paste 1072 in a dotted structure are connected with the optical adhesive 102, the upper polarizer 103, the color film substrate 104 and the array substrate 105, and the first conductive silver paste 1071 in a dotted structure and the second conductive silver paste 1072 in a dotted structure can reduce the risk that conductive silver paste 107 fragments fall into a chip, thereby reducing the problems of black screen and the like caused by the conductive silver paste 107 fragments.

It should be noted that the conductive silver paste 107 may also be of a linear structure, i.e., extending from the first conductive silver paste 1071 on the first side edge of the optical glue 102 to the second conductive silver paste 1072 on the second side edge of the optical glue 102. The first and second conductive silver pastes 1071 and 1072 are connected on the sides of the optical glue 102. It can be appreciated that the distance between the first conductive silver paste 1071 and the second conductive silver paste 1072 is equal to the length of the linear structure of the conductive silver paste 107. In some embodiments, the conductive silver paste 107 may extend from one side of the optical adhesive 102 to other positions of the first side. The linear conductive silver paste 107 is disposed at the edges of the optical adhesive 102 and the color filter substrate 104, and connects the optical adhesive 102, the upper polarizer 103 and the color filter substrate 104, and static electricity on the color filter substrate 104 is introduced into the optical adhesive 102 through the conductive silver paste 107.

A part of the conductive silver paste 107 is connected to one end of the optical adhesive 102, so that static electricity on the end surface of the upper polarizer 103 can be conducted out through a part of the conductive silver paste 107. It can be understood that, since the conductive particles 1021 are disposed in the optical adhesive 102, the conductive capability of guiding static electricity out of the color filter substrate 104 is increased, so that a portion of the conductive silver paste 107 may be tangentially connected to one end of the optical adhesive 102, and the first portion of the conductive silver paste 107 may be flush with the upper surface of the optical adhesive 102 on the side away from the color filter substrate 104. Since the conductive particles 1021 are provided in the optical paste 102, the entire optical paste 102 has conductivity. Therefore, a portion of the conductive silver paste 107 can completely wrap one end of the optical adhesive 102, increasing the contact area of the conductive channel for static dissipation, thereby improving the efficiency of static dissipation.

The array substrate 105 is disposed on a side of the color film substrate 104 away from the optical adhesive 102. The array substrate 105 is provided with a plurality of film transistors for driving the rotation of liquid crystal to control the display of each pixel, and an RGB color filter layer for forming the color of each pixel is provided on the color filter substrate. In the design process of the liquid crystal panel, the grounded part is arranged on the periphery of the array substrate 105, namely, a circle of GND (Ground, representing Ground or 0 line) metal wiring is arranged around the array substrate 105, because the dense circuit on the liquid crystal panel is easily influenced by static electricity, the purpose of setting the GND metal wiring is to rapidly release the static electricity through the GND metal wiring when the static voltage is generated, and the damage to the inside of the panel caused by static electricity accumulation and the display influence are prevented.

A part of the array substrate 105 is connected with a conductive silver paste 107, and is connected with the color film substrate 104, the upper polarizer 103, the optical adhesive 102 and the array substrate 105 through the conductive silver paste 107, that is, the conductive silver paste 107 extends from the edge of the optical adhesive 102 to the array substrate 105, so that static electricity on the color film substrate 104 sequentially passes through the upper polarizer 103, the optical adhesive 102, the conductive silver paste 107, the array substrate 105 and the grounding part, and is further led out for grounding dissipation. Through the conducting channel, static electricity on the color film substrate 104 can be dissipated quickly, and the problem that the static electricity on the color film substrate 104 cannot be dissipated is solved.

The upper polarizer 103 is arranged on one side of the color film substrate 104 far away from the array substrate 105, the edge of the upper polarizer 103 is connected with conductive silver paste 107, and static electricity at the end part of the upper polarizer 103 can be led out through the conductive silver paste 107. When the vertical projection of the color film substrate 104 on the array substrate 105 falls outside the vertical projection range of the upper polarizer 103 on the array substrate 105, that is, the projection area of the upper polarizer 103 on the array substrate 105 is smaller than the area of the color film substrate 104, a first step is formed between the color film substrate 104 and the end of the upper polarizer 103, and the first step is used for bearing part of the conductive silver paste 107. The conductive silver paste 107 extends from the outer surface of the optical adhesive 102 away from the upper polarizer 103 to the array substrate 105, so that static electricity on the color filter substrate 104 is conducted to the array substrate 105 through the conductive silver paste 107. Moreover, through the first step, the conductive silver paste 107 can be in full contact with the end of the upper polarizer 103 and in contact with the inner surface of the color film substrate 104 close to the cover plate 101, so that the contact area between the conductive silver paste 107 and the upper polarizer 103 and the optical adhesive 102 is increased, and the conductive effect of a conductive channel for introducing static electricity on the color film substrate 104 into the ground becomes better.

The lower polarizer 106 is disposed on a side of the array substrate 105 away from the color filter substrate 104, and vertical projections of the upper polarizer 103 and the lower polarizer 106 on the array substrate 105 are overlapped, that is, projection areas of the upper polarizer 103 and the lower polarizer 106 on the array substrate 105 are the same. Of course, in other embodiments, the projection areas of the upper polarizer 103 and the lower polarizer 106 may be different, for example, the projection area of the upper polarizer 103 is smaller than the projection area of the lower polarizer 106, or the projection area of the upper polarizer 103 is larger than the projection area of the lower polarizer 106.
