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, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments that can be obtained by a person skilled in the art without making any inventive step based on the embodiments in the present application belong to the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a display panel in the prior art, where the display panel 10 includes a substrate layer 11 and a functional film layer 1, which are stacked, and the functional film layer 1 includes an array layer 12, a light-emitting layer 13, and a cover plate 14, which are sequentially stacked. In the prior art, when the display panel 10 product is used in a dry environment, static electricity is easily generated due to the friction between the clothes and the cover plate 14, charges are accumulated on the surface of the cover plate 14 of the display panel 10, and if the charges accumulated for a long time are scattered in time, a strong potential body is formed on the surface of the cover plate 14 of the display panel 10, and thus problems such as abnormal display and the like are caused.
In order to solve the above problem, the present application provides a display panel 10, where the display panel 10 includes a substrate layer 11 and a functional film layer 1 that are stacked, and the functional film layer 1 deviates from the substrate layer 11 side, and a light-emitting surface 15 of the display panel 10 can generate opposite charges under the action of friction force. When the polarities of the charges are opposite, the positive charges and the negative charges on the light emitting surface 15 can be continuously neutralized, so that the probability of abnormal display of the display panel 10 caused by accumulation of the charges generated by electrostatic friction on the light emitting surface 15 is reduced, and the use experience of the display panel 10 is effectively improved.
Referring to fig. 2, fig. 2 is a schematic structural diagram of an embodiment of a display panel according to the present disclosure; the display panel 10 in the present application includes a substrate layer 11, a functional film layer 1, and a charge dissipation layer 2, where the charge dissipation layer 2 is located on at least a partial side of the substrate layer 11 and the functional film layer 1; the first surface 21 of the charge dispersion layer 2 on the light emitting surface 15 side of the display panel 10, a part of the side surface of the charge dispersion layer 2 and the second surface 17 of the functional film layer 1 can generate charges with opposite polarities under the action of friction force, and the first surface 21, the part of the side surface of the charge dispersion layer 2 and the second surface 17 form the light emitting surface 15. When the second surface 17 of the functional film 1 of the display panel 10 is subjected to a friction force during a friction process with clothes, etc., the second surface 17 of the functional film 1 generates static electricity and causes the display panel 10 to have a positive charge on the second surface 17. The first surface 21 and a part of the side surfaces of the charge dispersion layer 2 are subjected to friction force during the friction process with clothes, etc., and at this time, the first surface 21 and the charge dispersion layer 2 of the charge dispersion layer 2 generate static electricity, and the first surface 21 and a part of the side surfaces of the charge dispersion layer 2 are charged with negative charges. Under certain conditions, the positive charges carried by the display panel 10 on the second surface 17 and the negative charges carried by the charge evacuation layer 2 on the first surface 21 and a portion of the side surfaces can be continuously neutralized, so as to avoid any charge accumulation of the display panel 10 on the second surface 17, thereby avoiding the accumulation of charges generated by electrostatic friction on the second surface 17 of the functional film layer 1 to cause abnormal display of the display panel 10. In other embodiments, after being rubbed by an external force, the second surface 17 of the functional film layer 1 generates static electricity and carries positive charges; the first surface 21 and a part of the side surface of the charge dispersing layer 2 generate static electricity to carry negative charges, and because the second surface 17 and the first surface 21 have opposite polarities to the charges carried by the part of the side surface of the charge dispersing layer 2, the static electricity can be continuously neutralized under certain conditions, so that the static electricity is eliminated, and the influence caused by the static electricity is reduced or even eliminated.
Further, the first surface 21 and the second surface 17 are flush, or the first surface 21 and the plane of the second surface 17 form an included angle, and the included angle is located at the intersection of the first surface 21 and the second surface 17. On one hand, after the first surface 21 and a part of the side surfaces of the charge dispersion layer 2 and the second surface 17 of the display panel 10 are subjected to friction force to generate static electricity, the first surface 21 and a part of the side surfaces of the charge dispersion layer 2 are negatively charged, and the second surface 17 of the display panel 10 is positively charged; the first surface 21 and the second surface 17 are flush or the first surface 21 forms an angle with the plane of the second surface 17, providing conditions for neutralizing the negative charges carried by the first surface 21 and a part of the side surfaces of the charge evacuation layer 2 and the positive charges carried by the second surface 17 of the display panel 10. On the other hand, when the second surface 17 is subjected to a friction force, because the first surface 21 and the second surface 17 are flush or the first surface 21 and the plane of the second surface 17 form a certain included angle, the first surface 21 is also subjected to substantially the same friction force, so that static electricity is generated on both the first surface 21 and a part of the side surfaces of the charge evacuation layer 2 and the second surface 17, and thus negative charges generated on the first surface 21 and a part of the side surfaces of the charge evacuation layer 2 can be eliminated from positive charges generated on the second surface 17, thereby protecting the display panel 10. In practical application, when the first surface 21 protrudes from the second surface 17 by a certain distance, the static neutralization effect is not affected.
In other embodiments, the first surface 21 and a portion of the side surfaces of the charge dispersion layer 2 are positively charged, the second surface 17 of the display panel 10 is negatively charged, and the positive charges of the first surface 21 and the portion of the side surfaces of the charge dispersion layer 2 and the negative charges of the second surface 17 can be continuously neutralized under the condition that the first surface 21 and the second surface 17 are flush.
With reference to fig. 2, the charge dissipation layer 2 includes a first extension portion 22, the first extension portion 22 is disposed on at least a portion of the periphery of the side surface of the functional film layer 1; the first extension 22 of the charge-evacuating layer 2 is disposed on at least partial side periphery of the substrate layer 11 and the functional film layer 1 in a direction of the substrate layer 11 toward the cover plate 14, as shown in fig. 2, the first extension 22 may be disposed outside the light-emitting layer 13 and the cover plate 14, or the first extension 22 may be disposed outside the array layer 12, the light-emitting layer 13 and the cover plate 14. Alternatively, the first extension 22 may directly contact at least a part of the side surface of the functional film layer 1.
Preferably, please refer to fig. 3, wherein fig. 3 is a schematic structural diagram of another embodiment of the display panel in the present application; the first extension 22 is disposed on the periphery of all sides of the substrate layer 11 and the functional film layer 1. For example, the first extension 22 may be disposed outside of the substrate layer 11, the array layer 12, the light-emitting layer 13, and the cover plate 14. When the first extension portion 22 is disposed at the periphery of all sides of the substrate layer 11 and the functional film layer 1, a certain buffer protection effect can be provided for all sides of the substrate layer 11 and the functional film layer 1.
Referring to fig. 4, fig. 4 is a top view of an embodiment of a display panel according to the present application; in a plan view, that is, on a plane where the second surface 17 of the display panel 10 is located, the functional film layer 1 has four side surfaces, namely, a first side surface 141 and a second side surface 142 which are oppositely arranged in the X direction, and a third side surface 143 and a fourth side surface 144 which are oppositely arranged in the Y direction. The first extension 22 may be disposed at the second, third, and fourth sides 142, 143, 144. The design is suitable for the first extension portion 22 to be disposed on the second side 142, the third side 143, and the fourth side 144 when there are other devices on the first side 141 of the functional film 1 or the first side 141 needs to be bent, and the fabrication process is simple and the charge dissipation effect of the charge dissipation layer 2 can be ensured.

Referring to fig. 5, fig. 5 is a top view of another embodiment of a display panel of the present application; the first extension 22 may be disposed on the third side 143 and the fourth side 144. At this time, the first extension portion 22 of the charge evacuation layer 2 is symmetrically designed in the X direction, which is simple in design and facilitates the preparation of the charge evacuation layer 2. Meanwhile, when the first extension portion 22 is disposed only on the third side 143 and the fourth side 144, it is possible to achieve a sufficient antistatic effect and thus to ensure the charge evacuation effect of the charge evacuation layer 2.
Referring to fig. 6, fig. 6 is a schematic structural diagram of another embodiment of a display panel according to the present application; the first extending portion 22 includes a first extending sub-portion 221 and a first extending sub-portion 222, which are stacked, and the first extending sub-portion 221 is close to the light emitting surface 15 relative to the first extending sub-portion 222; wherein, the first extension sub-portion 221 and the functional film layer 1 can generate charges with opposite polarities under the action of friction force; the first extension portion 222 is electrically conductive; since the first extension sub-portion 221 is in communication with the first extension sub-portion 222, and the first extension sub-portion 222 is electrically conductive, electric charges generated by the first extension sub-portion 221 due to friction can be conducted through the first extension sub-portion 222.
Preferably, the functional film layer 1 includes a cover plate 14, a light-emitting layer 13, an array layer 12 and a substrate layer 11 which are stacked; the first extension sub-section 221 is disposed on the periphery of the side surfaces of the cover plate 14, the light-emitting layer 13, and the array layer 12, and the first extension sub-section 222 is disposed on the periphery of the backing layer 11. In the present embodiment, due to the design of the first extending subsection 221 and the first extending subsection 222, the width of the first extending subsection 221 and the width of the first extending subsection 222 are the same in the direction of the substrate layer 11 toward the cover plate 14.
Further, the material of the first extending sub-portion 221 includes at least one of conductive ink and conductive silica gel; and/or the material of the first extension portion 222 includes conductive glue.

When the cover plate 14 is made of glass, after the cover plate 14 is rubbed with clothes, the glass surface loses electrons and is positively charged, after part of the side surface and the first surface 21 of the charge evacuation layer 2 are rubbed with clothes and the like, the surface of the charge evacuation layer can obtain electrons and is negatively charged, or after a human body contacts conductive ink, the negative electricity can move to the conductive ink from the human body, so that the conductive ink is negatively charged. The light-emitting surface 15 of the display panel can generate charges with opposite electric quantity under the action of friction force, and the charges are continuously neutralized on the light-emitting surface 15, so that static electricity is reduced or even eliminated.
In another embodiment, when the first extending sub-portion 221 is made of a conductive silicone material, the polarity of the charges generated by the conductive silicone material is opposite to that of the charges generated by the cover 14 after the friction force of a human body or clothes is applied; the conductive silica gel material comprises a silica gel material containing conductive particles such as nickel-coated copper powder or silver powder. When the cover plate 14 is made of colorless polyimide CPI or polyethylene terephthalate PET, electrons on the surface of the cover plate 14 are negatively charged after the cover plate 14 is rubbed with clothes, and electrons on the surface of the cover plate 14 are lost and positively charged after part of the side surface and the first surface 21 of the charge evacuation layer 2 are rubbed with clothes, so that the light-emitting surface 15 of the display panel can generate charges with opposite positive and negative electric quantities under the action of friction force, and the charges are continuously neutralized on the light-emitting surface 15 to reduce or even eliminate static electricity. In addition, the material of the first extension portion 222 includes conductive adhesive, and the first extension portion 222 has conductivity.

With the second extension portion 23 disposed adjacent the substrate layer 11, the second extension portion 23 communicates with the first extension sub-portion 221 via the first extension sub-portion 222. When the display panel 10 rubs against the outside, the first surface 21 of the charge dispersion layer 2 on the light emitting surface 15 side of the display panel 10 will have negative charges after rubbing, and the second surface 17 of the functional film 1 can generate positive charges under the action of friction. The charges on the second surface 17 can be neutralized with the charges generated on the first surface 21, and when the display panel 10 further includes the second extension portion 23, a larger space can be provided for the neutralization of the positive charges on the second surface 17 and the negative charges generated on the first surface 21, so as to improve the charge neutralization efficiency and prevent the charge accumulation from being eliminated in time. At this time, the thickness of the second extension 23 in the direction of the substrate layer 11 toward the cover plate 14 may be 20 to 50 μm, while the area of the second extension 23 in the plane parallel to the second surface 17 is equal to the sum of the area of the substrate 11 and the area of the first extension branch 222 in the plane of the substrate 11, i.e., the second extension 23 covers the substrate 11 while being connected to the first extension branch 222. At this time, the first extension sub-portion 222 bonds the second extension portion 23 and the first extension sub-portion 221, and functions to conduct the charge transfer path.
Further, the material of the second extension portion 23 includes conductive ink. The charge generated by the conductive ink material is opposite in polarity to the charge generated by the cover plate 14 when subjected to frictional forces from a human body, clothing, or the like.
