Technical Field

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

[0002] Due to the limitations of screen wiring and bonding processes, existing display panels will form a visual effect that one side of the viewing frame area is much wider than the other three sides. This wide-side appearance can no longer meet the aesthetic needs of current consumers.

[0003] In order to improve the aesthetic appearance of display panels and enhance consumer satisfaction, it is urgent to improve display panels. Utility Model Content

[0004] The present application provides a display panel and a display device, which have a better aesthetic appearance.

[0005] In order to solve the above technical problems, the technical solution adopted in the present application is: to provide a display panel, the display panel is provided with a viewing frame area and a peripheral area located outside the viewing frame area, the display panel includes a screen layer, a touch bar and a touch layer, wherein the screen layer is located in the viewing frame area and the peripheral area; the touch bar is arranged on one side of the screen layer and is located in the peripheral area; the touch layer is arranged on the side of the touch bar away from the screen layer, and is located in the viewing frame area and the peripheral area.

[0006] Among them, by designing the touch bar between the touch layer and the screen layer, the distance between the touch bar and the screen layer is shortened, and the touch bar is optimized so that when the front light changes, the view frame area and the touch bar change in the same way, presenting a better view frame effect and improving the appearance aesthetics.

[0007] Wherein, the display panel further includes an adhesive layer, which is arranged between the screen body layer and the touch layer and is used to bond the screen body layer and the touch layer.

[0008] The screen body layer and the touch layer are bonded by using an adhesive layer to fix the position of the screen body layer and the touch layer.

[0009] Wherein, the touch bar is located between the adhesive layer and the screen layer.

[0010] Since the screen layer has an insulating film on one side near the touch layer, the touch strip is directly prepared on the surface, and then the screen layer with the touch strip formed is bonded to the touch layer to ensure a fixed connection between the screen layer and the touch layer.

[0011] The touch bar is located between the adhesive layer and the touch layer, and the display panel further includes an insulating layer formed between the touch bar and the touch layer.

[0012] In order to ensure the insulation effect between the touch layer and the touch bar, an insulating layer is prepared on the side of the touch layer close to the touch bar 20, so that the insulating layer is located between the touch layer and the touch bar, and then the touch layer with the prepared touch bar and the screen layer are bonded by an adhesive layer. This structure is simple to prepare and has a good insulation effect, ensuring the use effect of the display panel.

[0013] Wherein, the insulating layer includes at least one of ink and insulating oil.

[0014] Among them, one of insulating oil and ink can be used to insulate the touch layer, or a mixture of ink and insulating oil can be used to insulate the touch layer, which has a better insulation effect.

[0015] Wherein, in the direction from the screen layer to the touch layer, the thickness of the adhesive layer is in the range of 0.025-0.15 mm, and / or the material of the adhesive layer includes optical glue.

[0016] Among them, the low thickness of the adhesive layer can reduce the total thickness of the display panel, and is also beneficial to the preparation of the touch bar. The optical adhesive has good bonding performance, can meet the use requirements, and is easy to obtain materials, which is beneficial to the preparation of the display panel.

[0017] The touch layer includes a substrate and a touch conductive layer which are stacked, wherein the touch conductive layer is located on a side of the substrate away from the screen layer.

[0018] Among them, the substrate mainly provides support and protection for the preparation of the touch conductive layer, and the touch conductive layer is used to realize the touch function.

[0019] Wherein, in the direction from the screen layer to the touch layer, the thickness of the touch layer ranges from 0.01 to 0.1 mm, and / or, in the direction from the screen layer to the touch layer, the thickness of the touch strip ranges from 6 μm to 15 μm.

[0020] Among them, the ultra-thin design of the touch layer is conducive to reducing the thickness of the display panel and realizing ultra-thin display panels. Reducing the thickness of the touch bar and reducing the height difference between the touch bar and the screen layer is conducive to achieving consistent changes in the viewing frame area and the touch bar, presenting a better viewing frame effect.

[0021] Among them, the screen body layer is an ink screen body layer, and the display panel further includes an electromagnetic layer, a light guide layer, a cover layer and a handwriting layer. The electromagnetic layer, the screen body layer, the touch layer, the light guide layer, the cover layer and the handwriting layer are stacked in sequence.

[0022] Among them, the electromagnetic layer, the screen layer, the touch layer, the light guide layer, the cover plate layer, and the handwriting layer are sequentially stacked, so that the function of the display panel 100 is complete, and the service life and user satisfaction are improved.

[0023] In the first aspect of the embodiments of the present application, a display device is provided, which includes the display panel described in the above embodiments.

[0024] The beneficial effect is that in the present application, by designing the touch bar between the touch layer and the screen layer, the distance between the touch bar and the screen layer is reduced, and the touch bar is optimized. When the front light changes, the changes in the view frame area and the touch bar are consistent, presenting a better view frame effect and improving the appearance aesthetic.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes unlisted steps or units, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0034] Referring to Figure 1 、 Figure 2 and Figure 3 , the present application provides a display panel 100, which is provided with a border area 1 and a peripheral area 2 located outside the border area 1. The display panel 100 includes a panel layer 10, a touch bar 20, and a touch layer 30. Among them, the panel layer 10 is located in the border area 1 and the peripheral area 2; the touch bar 20 is disposed on one side of the panel layer 10 and is located in the peripheral area 2; the touch layer 30 is disposed on the side of the touch bar 20 away from the panel layer 10 and is located in the border area 1 and the peripheral area 2.

[0035] Specifically, the viewing area 1 of the display panel 100 is used to implement the display function, and the peripheral area 2 mainly includes the border and the area where the touch bar 20 is located. Both the screen layer 10 and the touch layer 30 are prepared as a whole surface, which is convenient for preparation. The screen layer 10 in the display panel 100 includes a plurality of sub-pixels for implementing light-emitting display. The touch bar 20 can support the common functions in the display panel 100. When the touch bar 20 is touched or clicked, the display panel 100 will execute the corresponding functions, such as page turning, etc. The touch layer 30 is used to make the viewing area 1 of the display panel 100 respond correspondingly according to the real-time clicks or touches of the user. At the same time, the touch bar 20 is located on one side of the screen layer 10, and the touch layer 30 is located on the side of the touch bar 20 away from the screen layer 10. In this application, by designing the touch bar 20 between the touch layer 30 and the screen layer 10, the distance between the touch bar 20 and the screen layer 10 is reduced, and the touch bar 20 is optimized to achieve that when the front light changes, the viewing area 1 and the touch bar 20 change in the same way, presenting a better viewing effect.

[0036] Please continue to refer to Figure 2 or Figure 3 , the display panel 100 further includes an adhesive layer 40, which is disposed between the screen layer 10 and the touch layer 30 for bonding the screen layer 10 and the touch layer 30. Using the adhesive layer 40 to bond the screen layer 10 and the touch layer 30 realizes the position fixation between the screen layer 10 and the touch layer 30, ensuring the stability of the display panel 100.

[0037] In one embodiment, in the direction from the screen layer 10 to the touch layer 30, the thickness range of the adhesive layer 40 is 0.025 - 0.15 mm. For example, the thickness range of the adhesive layer 40 can be 0.025, 0.05, 0.075, 0.1, 0.125 or 0.15 mm. A lower thickness of the adhesive layer 40 can reduce the total thickness of the display panel 100 and is also beneficial to the preparation of the touch bar 20.

[0038] In one embodiment, the material of the adhesive layer 40 includes optical adhesive (OCA). The optical adhesive has good bonding performance and high light transmittance. While meeting the usage requirements and being convenient for material acquisition, it can also ensure the light transmittance of the display panel 100, which is beneficial to the preparation of the display panel 100.

[0039] Please continue to refer to Figure 2 , in one embodiment, the touch bar 20 is located between the adhesive layer 40 and the screen layer 10. Specifically, during the preparation process, the touch bar 20 is first formed on one side of the screen layer 10 (specifically, the touch bar 20 can be formed by screen printing process). Since the surface of the screen layer 10 close to the touch layer 30 has an insulating film, the touch bar 20 can be directly prepared on this surface. Then, the screen layer 10 with the touch bar 20 formed and the touch layer 30 are bonded to ensure the fixed connection between the screen layer 10 and the touch layer 30.

[0040] Please continue reading Figure 3 In another embodiment, the touch bar 20 is located between the adhesive layer 40 and the touch layer 30, wherein the display panel 100 further includes an insulating layer 50, and the insulating layer 50 is formed between the touch bar 20 and the touch layer 30. Specifically, the touch bar 20 is prepared on the surface of the touch layer 30 close to the screen layer 10. In order to ensure the insulation effect between the touch layer 30 and the touch bar 20, the insulating layer 50 is prepared on the side of the touch layer 30 close to the touch bar 20, so that the insulating layer 50 is located between the touch layer 30 and the touch bar 20, and then the touch layer 30 and the screen layer 10 with the touch bar 20 prepared are bonded by the adhesive layer 40. This structure is simple to prepare and has a good insulation effect, which ensures the use effect of the display panel 100. In one embodiment, the touch bar 20 can be formed on the touch layer 30 by a silk screen printing process.

[0041] In one embodiment, the orthographic projection of the insulating layer 50 on the touch layer 30 covers the orthographic projection of the touch bar 20 on the touch layer 30, and the insulating layer 50 serves to isolate the touch layer 30 from the touch bar 20. In another embodiment, in order to ensure a good insulation effect, the orthographic projection of the insulating layer 50 on the touch layer 30 covers the touch layer 30. In another embodiment, in order to further ensure a good insulation effect, the insulating layer 50 extends from the surface of the touch layer 30 facing the screen layer 10 to the side of the touch layer 30.

[0042] In one embodiment, the insulating layer 50 includes at least one of ink and insulating oil. Specifically, one of the insulating oil and the ink can be used to insulate the touch layer 30, or a mixture of the ink and the insulating oil can be used to insulate the touch layer 30, thereby achieving a better insulating effect.

[0043] See also Figure 4 and Figure 5 In one embodiment, the touch layer 30 includes a stacked substrate 31 and a touch conductive layer 32, wherein the touch conductive layer 32 is located on the side of the substrate 31 away from the screen body layer 10. Specifically, the substrate 31 mainly provides support and protection for the preparation of the touch conductive layer 32, and the touch conductive layer 32 is used to realize the touch function. In this embodiment, the touch conductive layer 32 is arranged on the side of the substrate 31 away from the screen body layer 10, which can avoid the electrical connection between the touch conductive layer 32 and the touch bar 20 and ensure the insulation between the touch conductive layer 32 and the touch bar 20. Of course, in other embodiments, the touch conductive layer 32 can also be arranged on the side of the substrate 31 facing the screen body layer 10, as long as the insulation between the touch conductive layer 32 and the touch bar 20 is well done.

[0044] In one embodiment, if Figure 4As shown, the touch conductive layer 32 is in a metal grid shape, and this setting is beneficial to improving touch sensitivity. In one embodiment, the material of the touch conductive layer 32 includes copper to achieve a better conductive effect.

[0045] In one embodiment, in the direction from the screen layer 10 to the touch layer 30, the thickness range of the touch layer 30 is 0.01 - 0.1 mm. Specifically, the thickness of the touch layer 30 can be 0.01, 0.02, 0.04, 0.06, 0.08, or 0.1 mm. The ultra-thin design of the touch layer 30 is beneficial to reducing the thickness of the display panel 100 and realizing the ultra-thinning of the display panel 100.

[0046] In one embodiment, in the direction from the screen layer 10 to the touch layer 30, the thickness range of the touch bar 20 is 6 μm - 15 μm. Specifically, the thickness of the touch bar 20 can be 6 μm, 8 μm, 10 μm, 12 μm, 14 μm, or 15 μm. Reducing the thickness of the touch bar 20 and narrowing the height difference between the touch bar 20 and the screen layer 10 is beneficial to making the changes in the visual frame area 1 and the touch bar 20 consistent and presenting a better visual frame effect. In one embodiment, the material of the touch bar 20 includes ink. Further, the material of the touch bar 20 can be UV ink. The UV ink process is mature and convenient for the preparation of the touch bar 20.

[0047] Please refer to Figure 5 , the screen layer 10 is an ink screen layer, and the display panel 100 further includes an electromagnetic layer 60, a light guide layer 70, a cover layer 80, and a handwriting layer 90. The electromagnetic layer 60, the screen layer 10, the touch layer 30, the light guide layer 70, the cover layer 80, and the handwriting layer 90 are sequentially stacked. Specifically, there are many very small "microcapsules" attached in the electromagnetic layer 60, which encapsulate negatively charged black particles and positively charged white particles. By changing the charge, the different colored particles are arranged in an orderly manner, thus presenting a clear black-and-white visualization effect. At this time, the power consumption of the display panel 100 during use is extremely low, and only a small amount of electricity is required when switching the screen. In addition, it is a "reflective" reading medium like paper, using the reflection of ambient light to allow users to see the picture clearly. The main function of the light guide layer 70 is to evenly distribute external light sources in a darker environment to improve the display effect of the display panel 100. The main function of the handwriting layer 90 is to provide a writing experience similar to real paper, enabling users to write, draw, etc. on the display panel 100 while maintaining low power consumption and a good reading experience. The cover layer 80 plays a role in protecting the internal structure. The sequential stacking of the electromagnetic layer 60, the screen layer 10, the touch layer 30, the light guide layer 70, the cover layer 80, and the handwriting layer 90 makes the functions of the display panel 100 complete, improving the service life and user satisfaction.

[0048] The present application further provides a display device, which includes the display panel 100 in the above embodiments. The display device in the present application may be an electronic ink screen, which includes a display panel 100 and a border. The border can provide effective protection for the display panel 100 and improve the service life of the display device.

[0049] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
