Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a display screen and an electronic device. Background Art

[0002] In order to eliminate the static electricity generated on the panel, silver paste needs to be applied to the non-display area of ​​the panel. As a conductor with good conductivity, silver paste can conduct the static electricity on the panel to the circuit base layer of the non-display area to release the static electricity through grounding.

[0003] When applying silver paste, it is necessary to ensure that the silver paste can contact the polarizer, liquid crystal layer and circuit base layer. Therefore, in general processes, the applied silver paste is usually L-shaped; the applied silver paste needs to be cured, and high-temperature curing is generally used. However, under the action of high temperature, the curing order of the silver paste is from the outside to the inside, resulting in the silver paste curing on the outside while the internal silver paste is still relatively soft, which is easy to form bubbles or cause the loss of silver paste structural strength, resulting in silver paste collapse, collapse, incomplete coverage and other problems, which makes it difficult to release static electricity on the panel; on the other hand, since the silver paste contains a large number of highly oxidizing ions, and the liquid crystal layer and polarizer contain more reducing ions, if mutual ion diffusion occurs between the silver paste and the liquid crystal layer and / or the polarizer, it is easy to cause redox reactions, thereby causing a decrease in liquid crystal display performance and a decrease in the conductive effect of the silver paste; one of the pathways for ion diffusion is to enter through the gap at the junction of the polarizer and the liquid crystal layer. Summary of the invention

[0004] In view of the above situation, it is necessary to provide a display screen and an electronic device to address the problems of easy penetration and poor curing effect of silver paste in the prior art.

[0005] A display screen comprises a display screen body, wherein the display screen body comprises a liquid crystal layer and a polarizer arranged from bottom to top, wherein one side of the liquid crystal layer is a stepped structure, wherein the stepped structure is used to arrange silver paste, wherein a display area and a non-display area are formed on the display screen body, wherein the non-display area is located at the side edge of the display screen body, wherein the side walls of the polarizer facing the stepped structure are spaced inwardly to form a plurality of cavities, wherein the cavities are communicated with the top of the liquid crystal layer, wherein the cavities extend from the side walls of the polarizer to the top of the polarizer, wherein an inner sandwich component and a guide component are arranged in the cavity, wherein the inner sandwich component comprises an inner sandwich body penetrating the cavity, wherein the inner sandwich body is provided with a receiving cavity penetrating the inner sandwich body, wherein the receiving cavity is used to receive the guide component, wherein one end of the guide component extends out of the top of the polarizer and extends toward the side of the polarizer, and wherein the other end of the guide component is flush with the side of the polarizer.

[0006] Beneficial effects of the present invention:

[0007] Placing the inner sandwich component and the pin component on the polarizer in the non-display area will not affect the display effect in the display area, and the user's viewing experience is normal.

[0008] 1. A plurality of cavities are arranged at the silver paste origin position on the polarizer, and an inner interlayer component is arranged in the cavity, so that the inner interlayer component acts as a partition to isolate the side wall of the polarizer from the deep interface between the polarizer and the liquid crystal layer. This can significantly prevent the problem that after the silver paste is applied to the side wall of the polarizer, the oxidizing particles in the silver paste penetrate through the gap between the polarizer and the liquid crystal layer, causing the oxidizing particles in the silver paste to react with the reducing particles in the liquid crystal layer, thereby causing the display effect to deteriorate.

[0009] 2. The accommodating cavity of the inner sandwich component accommodates the guiding structure. First, the guiding structure forms a conductive loop from the polarizer to the silver paste and then to the liquid crystal layer. Conventional silver paste can only form a conductive loop from the side wall of the polarizer. When the static charge in the liquid crystal layer and the polarizer accumulates more or ages due to long-term use, resulting in enhanced edge resistance and affecting charge extraction, this conductive loop can significantly improve the efficiency of charge extraction and its continuous effective life; secondly, in the curing process after the silver paste is applied, the silver paste needs to be provided with heat from the outside to form dry curing. The heat is applied from the outside to the silver paste. Under normal circumstances, the direction of heat transfer is gradually transferred from the surface of the silver paste to the inside of the silver paste, that is, the curing direction of the silver paste is also from the outside to the outside. If the silver paste contains trace gases, during the high-temperature curing process, the gases will be squeezed into the silver paste along the curing direction and cannot be discharged, eventually forming bubbles inside and affecting the strength of the silver paste. The design of the guide structure allows part of the curing heat to be conducted along the guide structure, so that the back side of the silver paste can also get heat and gradually cure. Therefore, the curing direction is from outside to inside and from inside to outside at the same time. During the process, the gas in the silver paste can be discharged from the uncured part of the silver paste to the outside as the curing progresses, thereby reducing the generation of bubbles and improving the uniformity of curing. The curing strength is significantly improved, the bubble generation rate is reduced, and the yield rate of the electrostatic test and the silver paste strength test of the rear panel after the silver paste is applied is significantly improved.

[0010] Furthermore, the cavity has an L-shaped structure.

[0011] Furthermore, a horizontal length of the cavity does not exceed two thirds of a horizontal length of the non-display area.

[0012] Furthermore, the accommodating cavity includes a horizontal cavity and a vertical cavity, and the horizontal cavity is communicated with the vertical cavity.

[0013] Furthermore, the guiding assembly includes a first horizontal portion, a vertical portion and a second horizontal portion, the two ends of the vertical portion are respectively connected to the first horizontal portion and the second horizontal portion, the first horizontal portion is adapted to the horizontal cavity, the vertical portion is adapted to the vertical cavity, and the second horizontal portion is arranged at the top of the polarizer.

[0014] Furthermore, the width of the second horizontal portion is greater than or equal to the width of the vertical portion.

[0015] Furthermore, the length of the second horizontal portion is less than or equal to the length of the first horizontal portion.

[0016] Furthermore, the material of the inner interlayer body is a polymer material.

[0017] Furthermore, the guide component is made of one of silver paste, copper or graphene.

[0018] The present invention also provides an electronic device, comprising the above display screen. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Embodiment 1

[0031] A display screen, such as Figure 1 , Figure 3 and Figure 7 As shown, the display screen body 1 includes a liquid crystal layer 10 and a polarizer 20 arranged from bottom to top. The opposite side of the liquid crystal layer 10 is a step structure 30, and the step structure 30 is used to set the silver paste 40.

[0032] Specifically, Figures 1 to 7As shown, the display screen body 1 includes a display area 11 and a non-display area 12, the non-display area 12 is located at the side edge of the display screen body 1, and the side walls of the polarizer 20 facing the stepped structure 30 are concave to form a plurality of cavities 201 (not shown), the cavity 201 is an L-shaped structure, the cavity 201 is connected to the top of the liquid crystal layer 10, the cavity 201 extends from the side wall of the polarizer 20 to the top of the polarizer 20, the horizontal length of the cavity 201 does not exceed two-thirds of the horizontal length of the non-display area 12, an inner sandwich component 21 and a guide component 22 are provided in the cavity 201, the inner sandwich component 21 includes an inner sandwich body 211 penetrating the cavity 201, the inner sandwich body 211 is provided with a receiving cavity 212 penetrating the inner sandwich body 211, and the receiving cavity 212 is used to accommodate the guide component 22. The accommodating cavity 212 includes a horizontal cavity 2121 and a vertical cavity 2122. The horizontal cavity 2121 and the vertical cavity 2122 are connected. A plurality of cavities 201 are arranged at the position of the origin silver paste 40 on the polarizer 20. An inner interlayer component 21 is arranged in the cavity 201, so that the inner interlayer component 21 serves as a partition to isolate the side wall of the polarizer 20 from the deep interface where the polarizer 20 and the liquid crystal layer 10 are combined. After the silver paste 40 is applied, the oxidizing particles in the silver paste 40 penetrate through the gap between the polarizer 20 and the liquid crystal layer 10, causing them to react with the reducing particles in the liquid crystal layer 10, effectively reducing the ion migration in the liquid crystal layer 10 and the polarizer 20, thereby solving the problem of reduced display effect.

[0033] Specifically, the guide assembly 22 includes a first horizontal portion 221, a vertical portion 222, and a second horizontal portion 223. Both ends of the vertical portion 222 are connected to the first horizontal portion 221 and the second horizontal portion 223, respectively. The first horizontal portion 221 is adapted to the horizontal cavity 2121, and the vertical portion 222 is adapted to the vertical cavity 2122. One end of the first horizontal portion 221 is flush with the side of the polarizer 20, and one end of the vertical portion 222 connected to the second horizontal portion 223 extends to the top of the polarizer 20. The second horizontal portion 223 is provided at the top of the polarizer 20, and the second horizontal portion 223 extends toward the side direction of the polarizer 20. The inner interlayer assembly is provided on the polarizer 20 in the non-display area 12. The components and guiding components form a plurality of heat conduction channels between the liquid crystal layer 10 and the polarizer 20, extending from the side of the polarizer 20 to the top of the polarizer 20. After the silver paste 40 is applied, a complete heat conduction channel is formed from the liquid crystal layer 10 to the silver paste to the side of the polarizer 20 and then to the top of the polarizer 20, so that the silver paste solidification can be conducted from the first horizontal portion 221 and the second horizontal portion 223 to the vertical portion 222 respectively. In addition, the heat conduction channel is also a conductive circuit. When static charge accumulates more in the liquid crystal layer 10 and the polarizer 20 or ages due to long-term use, resulting in enhanced edge resistance affecting charge extraction, the conductive circuit can significantly improve the efficiency of charge extraction and its continuous effective life.

[0034] Specifically, the width of the second horizontal portion 223 is equal to the width of the vertical portion 222, and the length of the second horizontal portion 223 is less than the length of the first horizontal portion 221. It should be noted that the connection between the first horizontal portion 221 and the second horizontal portion 223 and the vertical portion 222 respectively serves as the length of the first horizontal portion 221 and the second horizontal portion 223.

[0035] Specifically, the material of the inner interlayer body 211 is a polymer material, which is an inert or neutral material that is not easily oxidized or reduced.

[0036] Specifically, the material of the guide component 22 is one of silver paste, copper or graphene, and the material of the guide component 22 has both good thermal conductivity and electrical conductivity.

[0037] Embodiment 2

[0038] The difference from the first embodiment is that:

[0039] Specifically, the width of the second horizontal portion 223 is greater than the width of the vertical portion 222, and the length of the second horizontal portion 223 is equal to the length of the first horizontal portion 221, so that the contact area between the second horizontal portion 223 and the top of the polarizer 20 is larger, and the guiding component 22 has better thermal and electrical conductivity.

[0040] Embodiment 3

[0041] The difference from the first embodiment is that:

[0042] Specifically, the width of the second horizontal portion 223 is greater than the width of the vertical portion 222 , so that the contact area between the second horizontal portion 223 and the top of the polarizer 20 is relatively large, and the guide assembly 22 has better heat and electricity conduction effects.

[0043] Embodiment 4

[0044] The difference from the first embodiment is that:

[0045] Specifically, the length of the second horizontal portion 223 is equal to the length of the first horizontal portion 221 , so that the contact area between the second horizontal portion 223 and the top of the polarizer 20 is relatively large, and the guide assembly 22 has better heat and electricity conduction effects.

[0046] In summary, arranging the inner interlayer component 21 and the pin component 22 on the polarizer 20 of the non-display area 12 will not affect the display effect of the display area 11, and the user's viewing experience is normal.

[0047] A plurality of cavities 201 are provided at the position of the origin silver paste 40 on the polarizer 20, and an inner interlayer component 21 is provided in the cavity 201, so that the inner interlayer component 21 serves as a partition to isolate the side wall of the polarizer 20 from the deep interface between the polarizer 20 and the liquid crystal layer 10. This significantly prevents the problem that after the silver paste 40 is applied to the side wall of the polarizer 20, the oxidizing particles in the silver paste 40 penetrate into the gap between the polarizer 20 and the liquid crystal layer 10, causing the oxidizing particles in the silver paste 40 to react with the reducing particles in the liquid crystal layer 10, thereby causing a decrease in the display effect.

[0048] The accommodating cavity of the inner interlayer component 21 accommodates the guiding structure 22. First, the guiding structure 22 forms a conductive loop from the polarizer 20 to the silver paste 40 and then to the liquid crystal layer 10. Conventionally, the silver paste 40 can only form a conductive loop from the side wall of the polarizer 20. When the static charge in the liquid crystal layer 10 and the polarizer 20 accumulates a lot or ages due to long-term use, resulting in enhanced edge resistance and affecting charge extraction, the conductive loop can significantly improve the efficiency of charge extraction and the continuous effective life; secondly, in the curing process after the silver paste 40 is applied, the silver paste 40 needs to be provided with heat from the outside to form dry curing, and the heat is applied from the outside to the silver paste 40. Under normal circumstances, the heat transfer direction is gradually transferred from the surface of the silver paste 40 to the inside of the silver paste 40, that is, the curing direction of the silver paste 40 is also from the outside to the inside. If the silver paste 40 contains trace gas, during the high-temperature curing process, the gas will be squeezed into the silver paste 40 along the curing direction and cannot be discharged, and eventually bubbles will be formed inside, affecting the strength of the silver paste 40. The design of the guide structure 22 allows a portion of the curing heat to be conducted along the guide structure, and the heat flows from the second horizontal part 223 to the vertical part 222 and then to the first horizontal part 221. The silver paste 40 obtains heat and gradually cures. Therefore, the curing direction is from outside to inside and from inside to outside at the same time. During the process, the gas in the silver paste 40 can be discharged from the uncured part of the silver paste 40 to the outside as the curing proceeds, thereby reducing the generation of bubbles and improving the uniformity of curing. The curing strength is significantly improved, the bubble generation rate is reduced, and the yield rate of the electrostatic test and the silver paste strength test of the rear panel after the silver paste is applied is significantly improved.
