[0036] With the development of optoelectronic display technology and semiconductor manufacturing technology, the liquid crystal display panel (Thin Film Transistor-Liquid Crystal Display, TFT-LCD) matched with thin film transistor has become more and more mature, and has been more and more widely used due to its advantages of lightness, thinness, portability and the like.
[0037] Among them, the liquid crystal panel display structure can also be a common twisted nematic liquid crystal (TN) mode, in-plane switching liquid crystal (IPS) mode or fringe field switching liquid crystal (FFS) mode and the like.
[0038] The TN display panel mode is to place the nematic liquid crystal between two glass substrates each having a transparent electrode, the polarization axes of the polarizing sheets on the two glass substrates are perpendicular and orthogonal, and the liquid crystal molecules are in a 90° twisted alignment structure in the display screen; when no voltage is applied to the two transparent electrodes, the incident light is deflected by 90° after passing through the polarization axis of the T-side (the side where the array substrate is located) polarizing sheet, and then is emitted out of the polarization axis of the C-side (the side where the color film substrate is located) polarizing sheet, at this time, the display screen is in a white state; when a voltage is applied to the two transparent electrodes, a vertical electric field is formed between the two transparent electrodes, the liquid crystal molecules change from the twisted structure to the vertical arrangement, the incident light is not deflected after passing through the polarization axis of the T-side polarizing sheet, is parallel to the polarization axis of the C-side polarizing sheet and directly enters the absorption axis of the C-side polarizing sheet, and therefore the light is absorbed and no light is emitted out, at this time, the display screen is in a black state. This display mode of the TN display panel is also called "common white mode".
[0039] The TN display panel has the advantages of fast response time and fast deflection speed of liquid crystal molecules, but in the related art, the electrical connection between the color film substrate and the array substrate inside the TN display panel is prone to failure, so that the TN display panel cannot work. How to effectively avoid the electrical connection between the color film substrate and the array substrate inside the TN display panel from being prone to failure becomes a technical problem to be solved.
[0040] Please refer to Figure 1 and Figure 2 , Figure 1 is a cross-sectional structure schematic diagram of a display panel provided by the first embodiment of the present application, Figure 2 is a display surface division schematic diagram of a display panel provided by the first embodiment of the present application. The present application provides a display panel 1 to solve the technical problem of how to effectively avoid the electrical connection between the color film substrate and the array substrate inside the TN display panel from being prone to failure.
[0041] The display panel 1 comprises a color film substrate 10, an array substrate 20, and a first conductive structure 30. The color film substrate 10 comprises a first common electrode 11. The array substrate 20 is oppositely and spacedly arranged with the color film substrate 10, and comprises at least one electrode assembly 21. The first conductive structure 30 is arranged between the color film substrate 10 and the array substrate 20, and comprises a support assembly 31 and a conductive layer 32. The support assembly 31 is arranged on the array substrate 20, the conductive layer 32 covers the outer surface of the support assembly 31 and electrically connects the electrode assembly 21 on the array substrate 20. The support assembly 31 can extend in the direction close to the color film substrate 10, so that the support assembly 31 electrically connects the first common electrode 11 on the conductive layer 32 on the color film substrate 10.
[0042] Meanwhile, the support assembly 31 is also capable of being retracted in a direction away from the color filter substrate 10, so as to make the conductive layer 32 spaced apart from the first common electrode 11.
[0043] The display panel 1 has a display area 101 and a non-display area 102, the non-display area 102 is arranged around the display area 101. Specifically, the display area 101 can be used for displaying pictures, and the non-display area 102 is used for arranging the components and signal lines required by the display panel 1, and the first conductive structure 30 is arranged in the non-display area 102 of the display panel 1.
[0044] The array substrate 20 is arranged opposite and spaced apart from the color filter substrate 10, and the display area 101 and the non-display area 102 of the display panel 1 are both provided with at least part of the array substrate 20 and at least part of the color filter substrate 10. A liquid crystal module is arranged between the array substrate 20 and the color filter substrate 10 in the display area 101 of the display panel 1, and the liquid crystal module includes a plurality of liquid crystal molecules.
[0045] The first common electrode 11 of the color filter substrate 10 and the pixel electrode on the array substrate 20 form a pressure difference, thereby controlling the deflection of the liquid crystal molecules, so that the incident light is emitted through the liquid crystal module and the color filter substrate 10.
[0046] In this embodiment, the display panel 1 is taken as a TN mode display panel for example, which should not be understood as a limitation to the present application. It should be noted that the TN mode of the display panel 1 is taken as a common white mode for example in the present application.
[0047] The array substrate 20 is provided with a first polarizer, and the color filter substrate 10 is provided with a second polarizer, and the polarization axis of the first polarizer is perpendicular and orthogonal to the polarization axis of the second polarizer.
[0048] Specifically, in the initial state, a plurality of the liquid crystal molecules in the display panel 1 are in a 90° twisted alignment structure, and the liquid crystal molecules close to one side of the second polarizer on the color filter substrate 10 are parallel to the polarization axis direction of the second polarizer, the incident light is incident into the liquid crystal module from one side of the array substrate 20, and is deflected by 90° after passing through a plurality of the liquid crystal layers in the liquid crystal module, and is emitted from the second polarizer on one side of the color filter substrate 10, at this time, the display panel 1 presents a bright state.
[0049] When the display panel 1 needs to present a dark state, the electrode assembly 21 of the array substrate 20 needs to apply a voltage and transmit the voltage to the first common electrode 11 of the color film substrate 10 through the conductive structure between the substrates, so that the liquid crystal molecules in the liquid crystal module can change from a twisted structure to a vertical arrangement under the action of an electric field. After the incident light enters the liquid crystal module from one side of the array substrate 20, the incident light is not deflected and is absorbed by the second polarizer of the color film substrate 10. The incident light in the display panel 1 cannot be emitted, and thus the display panel 1 presents a dark state.
[0050] The first conductive structure 30 is arranged between the color film substrate 10 and the array substrate 20, and the first conductive structure 30 electrically connects the first common electrode 11 of the color film substrate 10 and the electrode assembly 21 of the array substrate 20. The first conductive structure 30 is used to transmit an electrical signal of the electrode assembly 21 to the first common electrode 11, so that the first common electrode 11 and the electrode assembly 21 can apply the same voltage, and thus the display panel 1 can present a dark state.
[0051] Specifically, the first conductive structure 30 includes the support assembly 31 and the conductive layer 32, and the conductive layer 32 covers the outer surface of the support assembly 31 and is electrically connected to the electrode assembly 21 on the array substrate 20. The support assembly 31 can extend in a direction close to the color film substrate 10, so that the support assembly 31 electrically connects the first common electrode 11 on the conductive layer 32 on the color film substrate 10, so that the first common electrode 11 and the electrode assembly 21 can be electrically connected and apply the same voltage.
[0052] The material of the conductive layer 32 is a flexible conductive material, and optionally, the material of the conductive layer 32 includes but is not limited to a metal material, a composite material, or other materials. For example, the conductive layer 32 can be a metal material with excellent ductility and non-reactivity, such as silver or copper.
[0053] The display panel 1 provided in the present application, the first conductive structure 30 is arranged between the color film substrate 10 and the array substrate 20, the first conductive structure 30 comprises a support assembly 31 and a conductive layer 32, the support assembly 31 is arranged on the array substrate 20, the conductive layer 32 covers the outer surface of the support assembly 31 and is electrically connected to the electrode assembly 21 on the array substrate 20, the support assembly 31 can extend in the direction close to the color film substrate 10, so that the support assembly 31 is electrically connected to the first common electrode 11 on the color film substrate 10 through the conductive layer 32. When the distance between the color film substrate 10 and the array substrate 20 is greater than or less than the preset distance, the support assembly 31 can extend in the direction close to the color film substrate 10, which can improve the probability of electrical connection between the first common electrode 11 and the electrode assembly 21, improve the stability of electrical connection between the first common electrode 11 and the electrode assembly 21, and effectively avoid the problem that the electrical connection between the color film substrate 10 and the array substrate 20 of the display panel 1 is easy to fail.
[0054] Please refer again to Figure 1 Further, the support assembly 31 further comprises an electrostrictive layer 311 and a support piece 312, the electrostrictive layer 311 is arranged on the array substrate 20, the support piece 312 is arranged on the side of the electrostrictive layer 311 away from the array substrate 20, and the conductive layer 32 is arranged on the side of the support piece 312 close to the color film substrate 10, and the electrostrictive layer 311 can extend or contract in the direction close to or away from the color film substrate 10.
[0055] The electrostrictive layer 311 can extend or contract under the action of an electric field, drive the support piece 312 to move in the direction close to or away from the color film substrate 10, and then drive the conductive layer 32 to move in the direction close to or away from the color film substrate 10.
[0056] Optionally, the material of the electrostrictive layer 311 includes but is not limited to ion-exchange polymer metal composite (IPMC) or other materials.
[0057] In the present embodiment, the support piece 312 is a PS pillar, and the support piece 312 is made of elastic material. If the interval distance between the color film substrate 10 and the array substrate 20 becomes larger, the support piece 312 can rebound by a part of length, so that the conductive layer 32 continues to abut against the first common electrode 11 of the color film substrate 10. The rebounding size of the support piece 312 accounts for 5% of the total length of the support piece 312.
[0058] Please refer again to Figure 1The array substrate 20 further comprises a voltage-changing electrode 22, which is oppositely spaced from the first common electrode 11 and is arranged on the side of the electrostrictive layer 311 away from the first common electrode 11. A preset electric field is formed between the voltage-changing electrode 22 and the first common electrode 11, and the electrostrictive layer 311 can be stretched or shrunk in the direction of approaching or departing from the first common electrode 11 in the preset electric field.
[0059] The voltage of the voltage-changing electrode 22 can be adjusted to adjust the electric field intensity of the preset electric field formed between the voltage-changing electrode 22 and the first common electrode 11, thereby adjusting the size of the electrostrictive layer 311 stretched or shrunk in the direction of approaching or departing from the first common electrode 11 in the preset electric field.
[0060] Specifically, the greater the voltage difference between the voltage-changing electrode 22 and the first common electrode 11, the greater the size of the electrostrictive layer 311 stretched or shrunk in the direction of approaching or departing from the first common electrode 11 in the preset electric field.
[0061] It should be noted that, alternatively, the electrostrictive layer 311 can be stretched in the direction of approaching the first common electrode 11 when the voltage of the voltage-changing electrode 22 is greater than the voltage of the first common electrode 11, and the electrostrictive layer 311 can be shrunk in the direction of departing from the first common electrode 11 when the voltage of the voltage-changing electrode 22 is less than the voltage of the first common electrode 11; or the electrostrictive layer 311 can be shrunk in the direction of departing from the first common electrode 11 when the voltage of the voltage-changing electrode 22 is greater than the voltage of the first common electrode 11, and the electrostrictive layer 311 can be stretched in the direction of approaching the first common electrode 11 when the voltage of the voltage-changing electrode 22 is less than the voltage of the first common electrode 11. The above all belong to the embodiments of the present application.
[0062] Please refer to Figure 1 The conductive layer 32 comprises a first conductive part 321 and a second conductive part 322 connected with each other. The first conductive part 321 is arranged on the outer surface of the support assembly 31 and electrically connected with the first common electrode 11. The second conductive part 322 is arranged on the array substrate 20 and electrically connected with the electrode assembly 21.
[0063] The first conductive part 321 is arranged on the outer surface of the support assembly 31 and covers at least part of the support assembly 31. The conductive layer 32 electrically connects the first common electrode 11 with the electrode assembly 21 through the first conductive part 321 and the second conductive part 322.
[0064] Please refer to Figure 3 , Figure 3is a schematic diagram of a cross-sectional structure of a display panel provided in the second embodiment of the present application. In another embodiment, the conductive layer 32 further comprises a third conductive part 323 electrically connected to the first conductive part 321 and the second conductive part 322, the third conductive part 323 is arranged between the electrostrictive layer 311 and the support 312, and the third conductive part 323 is arranged corresponding to the variable voltage electrode 22.
[0065] The first conductive part 321 is electrically connected to the first common electrode 11, and the third conductive part 323 is electrically connected to the first conductive part 321, so that the voltage of the third conductive part 323 is the same as the voltage of the first common electrode 11. The third conductive part 323 is arranged between the electrostrictive layer 311 and the support 312, and a preset electric field can also be formed between the third conductive part 323 and the variable voltage electrode 22. The third conductive part 323 is closer to the variable voltage electrode 22 than the first common electrode 11, and the preset electric field between the third conductive part 323 and the variable voltage electrode 22 is better than the electric field between the first common electrode 11 and the variable voltage electrode 22.
[0066] Please refer to Figure 1 , the electrode assembly 21 comprises a second common electrode 211 and a connecting electrode 212, the connecting electrode 212 covers at least part of the second common electrode 211, and the second common electrode 211 transmits electrical signals to the conductive layer 32 through the connecting electrode 212.
[0067] The connecting electrode 212 covers at least part of the second common electrode 211, which can be used to avoid the second common electrode 211 from being eroded by water vapor in the external environment.
[0068] Optionally, the material of the connecting electrode 212 includes but is not limited to N-type oxide semiconductor-indium tin oxide (ITO) or other materials with good conductive properties.
[0069] The variable voltage electrode 22 is arranged in a layer different from the second common electrode 211, so as to avoid mutual interference between the electrical signals on the variable voltage electrode 22 and the electrical signals on the second common electrode 211.
[0070] Please refer to Figure 1 In the present embodiment, the display panel 1 further comprises a second conductive structure 41 arranged between the color filter substrate 10 and the array substrate 20, the second conductive structure 41 can electrically connect the first common electrode 11 and the electrode assembly 21, and conduct the electrical signals of the electrode assembly 21 to the first common electrode 11.
[0071] Specifically, in the embodiment, the second conductive structure 41 is a conductive gold ball. The second conductive structure 41 conducts the electrical signal of the electrode assembly 21 to the first common electrode 11, so that the second common electrode 211 of the electrode assembly 21 and the first common electrode 11 are loaded with the same common voltage, ensuring that the display panel 1 can work normally.
[0072] Optionally, the conductive gold ball is generally made of a resin material or a plastic with a gold shell wrapped outside, and has vertical direction conductivity.
[0073] Please refer again to Figure 1 In the embodiment, the display panel 1 further includes a first frame glue 51 abutting the color film substrate 10 and the array substrate 20, respectively, and the second conductive structure 41 is arranged in the first frame glue 51.
[0074] The first frame glue 51 abuts the color film substrate 10 and the array substrate 20, respectively, and the first frame glue 51 bonds the color film substrate 10 and the array substrate 20, respectively, so that the color film substrate 10 and the array substrate 20 are relatively fixed.
[0075] The second conductive structure 41 is arranged in the first frame glue 51, and the first frame glue 51 can also be used to fix the second conductive structure 41, avoiding displacement of the second conductive structure 41 and causing electrical connection failure in the display panel 1.
[0076] It should be noted that the first frame glue 51 itself is an insulating material, and the second conductive structure 41 needs to break through the first frame glue 51 to contact the first common electrode 11 and the electrode assembly 21, so as to transmit the electrical signal of the second common electrode 211 to the first common electrode 11.
[0077] However, in the related art, during the preparation of the display panel, due to the influence of the preparation process, the first frame glue is prone to be higher than the conductive gold ball, which causes the conductive gold ball to fail to contact the electrode assembly and the first common electrode at the same time, the electrical signal of the second common electrode cannot be transmitted to the first common electrode, the display panel fails to display, and cannot work. The situation that the first frame glue is higher than the conductive gold ball includes the following two cases, first, the conductive gold ball is prepared too small due to the preparation process problem, and second, the first frame glue is prepared too high due to the preparation process problem.
[0078] The display panel 1 provided in the present application, if the conductive gold ball (second conductive structure 41) is too small due to the preparation process problem, the first conductive structure 30 can be used as a backup conductive structure for conduction, thereby improving the electrical connection stability between the color film substrate 10 and the array substrate 20 of the display panel 1. If the first frame glue 51 is too high due to the preparation process problem, the distance between the color film substrate 10 and the array substrate 20 is greater than the preset distance, and the support component 31 in the first conductive structure 30 can extend in the direction close to the color film substrate 10, so that the conductive layer 32 of the first conductive structure 30 can electrically connect the first common electrode 11, thereby making the first common electrode 11 and the second common electrode 211 electrically connected, and improving the electrical connection stability between the color film substrate 10 and the array substrate 20 of the display panel 1.
[0079] Please refer to Figure 4 , Figure 4 is a schematic diagram of the position of the second common electrode and the variable voltage electrode provided in the first embodiment of the present application. In the present embodiment, the variable voltage electrode 22 surrounds the second common electrode 211.
[0080] Please refer to Figure 1 and Figure 5 , Figure 5 is a schematic diagram of the cross-sectional structure of a display panel provided in the third embodiment of the present application. The display panel 1 further comprises a third conductive structure 42 disposed between the color film substrate 10 and the array substrate 20, and the third conductive structure 42 can electrically connect the first common electrode 11 and the electrode component 21, and conduct the electrical signal of the electrode component 21 to the first common electrode 11.
[0081] Specifically, in the present embodiment, the third conductive structure 42 is a conductive gold ball.
