AI Technical Summary
In existing technologies, when a display screen with an ultra-narrow bezel design is bent, the film layer boundary is easily subjected to stress and breaks, especially in the bending area, leading to reliability and lifespan issues for the display screen.
A baffle is set in the array substrate layer of the display body, and the first sub-part of the drive control board is extended to the baffle to avoid the boundary position in order to reduce stress concentration. Combined with the groove design, it prevents moisture intrusion and enhances structural stability.
This effectively prevents the array substrate layer from cracking due to stress concentration at the boundary, improves the bending reliability and service life of the display body, and achieves stability in the narrow bezel design.

Description
Technical Field
[0001] This application relates to the field of display panel technology, and in particular to a display screen body, display panel and display device. Background Technology
[0002] Nowadays, the market demand for products with high screen-to-body ratios is increasing, which in turn leads to higher requirements for narrow bezels.
[0003] However, due to the limitations of ultra-narrow bezel displays, especially those with a bent design, the stress on the bottom bezel of the screen will be applied to the film layer boundary inside the display body. In other words, after the bottom bezel of the screen is bent, the film layer boundary of the narrow bezel display body, which is closer to the bending area, will be more susceptible to the bending stress, thus causing the film layer boundary to be prone to breakage under stress. Summary of the Invention
[0004] The main technical problem addressed by this application is to provide a display screen body, a display panel, and a display device to solve the problem that the film layer boundary of the display screen body in the prior art is prone to breakage under stress.
[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a display screen body having a display area and a non-display area, wherein the display screen body includes: an array substrate layer having a first portion and a second portion respectively corresponding to the display area and the non-display area; a barrier wall disposed on the first portion; and a drive control substrate including a first sub-part and a second sub-part connected to each other, the second sub-part being disposed on the second portion, one end of the first sub-part being connected to the second sub-part, and the other end of the first sub-part extending to be connected to the barrier wall.
[0006] The second sub-part has a groove located away from the first sub-part.
[0007] The depth of the groove is less than or equal to the thickness of the second sub-part.
[0008] The thickness of the first sub-section is less than the thickness of the retaining wall.
[0009] The display screen body also includes an encapsulation substrate layer, which is disposed in the first section and covers the retaining wall, the first subsection and part of the second subsection.
[0010] The display body also includes a touch substrate layer, which is disposed on the encapsulation substrate layer, part of the second sub-part, and the groove wall and bottom.
[0011] The display screen also includes a curing film protective layer, which is disposed on the touch substrate layer and part of the second sub-part.
[0012] The display screen also includes a polarizer, which is disposed on the curing film protective layer, and the orthogonal projection of the polarizer on the array substrate layer covers the entire first section.
[0013] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a display panel, wherein the display panel includes: a base layer, a display body and a cover plate stacked in sequence; wherein the display body is the display body as described in any of the above claims.
[0014] To solve the above-mentioned technical problems, another technical solution adopted in this application is: to provide a display device, wherein the display device includes a display panel and a housing connected to each other; wherein the display panel is the display panel as described in any of the above claims.
[0015] The beneficial effects of this application are as follows: Unlike the prior art, the display screen body provided by this application has a display area and a non-display area. The array substrate layer in the display screen body has a first portion and a second portion respectively corresponding to the display area and the non-display area. A baffle is disposed on the first portion. The drive control substrate includes a first sub-part and a second sub-part connected to each other. The second sub-part is disposed on the second portion. One end of the first sub-part is connected to the second sub-part, and the other end of the first sub-part extends to the baffle. The array substrate layer in the baffle has a first portion and a second portion, and its baffle is disposed on the first portion. By extending the drive control substrate to the baffle located in the first portion of the array substrate layer, the boundary position of the first portion and the second portion of the array substrate layer avoids the boundary of the drive control substrate, thereby effectively avoiding the risk of the array substrate layer breaking due to stress concentration at the boundary position when the drive control substrate is bent.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0024] The present application will now be described in detail with reference to the accompanying drawings and embodiments.
[0025] Please refer to the following: Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the structure of the first embodiment of the display screen of this application. Figure 2 yes Figure 1 A detailed partial structural diagram of one embodiment of the display screen body 10. In this embodiment, the display screen body 10 specifically includes: an array substrate layer 11, a barrier 12, and a drive and control substrate 13.
[0026] Specifically, the display body 10 can be understood as a packaged module in which various functional devices and conductive lines are encapsulated in the display panel for signal interaction with external signal processing circuits and display of images. It can be manufactured separately or directly formed on the corresponding substrate layer, and a cover plate (not shown) is further formed on the display body 10 to obtain the corresponding display panel product.
[0027] It is worth noting that the base layer is specifically used to provide strength support for the display body 10, while the cover plate is specifically used to cover the display body 10 to provide protection for the display body 10.
[0028] Specifically, the display screen body 10 has a display area 101 and a non-display area 102, while the array substrate layer 11 has a first portion 111 and a second portion 112 respectively corresponding to the display area 101 and the non-display area 102.
[0029] Specifically, the array substrate layer 11 has each light-emitting device and each switching device encapsulated in its central position, which can be referred to as the first section 111. In order to realize the driving control of each switching device to drive each light-emitting device to emit light and enable the first section 111 to display the image, each designed conductive line is also encapsulated at the edge of the array substrate layer 11, which can be referred to as the second section 112. The designed conductive line extends to the first section 111 to connect to each light-emitting device and each switching device, and connects to an external signal processing circuit to realize signal interaction with the processing circuit, thereby realizing the corresponding image display.
[0030] Understandably, in order to prevent external moisture from entering the first section 111 of the array substrate layer 11 and causing adverse effects on the functional devices and ultimately affecting the display effect, a baffle 12 is specifically provided in the first section 111 of the array substrate layer 11. The baffle 12 is specifically located on the first section 111 near the boundary of the second section 112 and surrounds the center of the first section 111.
[0031] Furthermore, the drive control substrate 13 specifically includes a first sub-part 131 and a second sub-part 132 connected to each other. The second sub-part 132 is disposed on the second sub-part 112, and one end of the first sub-part 131 is connected to the second sub-part 132. The other end of the first sub-part 131 extends toward the first sub-part 111 and is connected to the retaining wall 12.
[0032] The above solution extends the drive control substrate 13 to the barrier 12 located in the first part 111 of the array substrate layer 11, so that the boundary between the first part 111 and the second part 112 of the array substrate layer 11 avoids the boundary of the drive control substrate 13. This effectively avoids the risk of the array substrate layer 11 breaking due to stress concentration at the boundary when the drive control substrate 13 is bent.
[0033] Understandably, the first portion 111 of the display body 10 corresponding to the array substrate layer 11 is usually thicker than its second portion 112. Therefore, when the third sub-part of the drive control substrate 13 is bent, it is easy to break at the dividing position. By extending the first sub-part 131 of the drive control substrate 13 to the barrier 12 located at the first portion 111 of the array substrate layer 11, the film layer boundary of the drive control substrate 13 at the dividing position is effectively avoided, thus effectively reducing the risk of the array substrate layer 11 breaking due to the stress concentration caused by bending at the dividing position.
[0034] It is worth noting that the drive control substrate 13 is specifically packaged or mounted with drive control circuits and connection lines, so that it can be connected to each functional device and designed conductive line in the array substrate layer 11 through the drive control circuits and connection lines, thereby driving and controlling each functional device to achieve the corresponding screen display.
[0035] In some embodiments, the non-display area 102 of the display body 10 further includes a first non-bending area 1021, a bending area 1022, and a second bending area 1023. One end of the first non-bending area 1021 is connected to the display area, and the other end of the first non-bending area 1021 is connected to one end of the bending area 1022. The other end of the bending area 1022 is bent and extended toward a side away from the display direction of the display area 101 and is connected to one end of the second bending area 1023. The other end of the second bending area 1023 is extended toward the display area 101, so that the structural portions of the display body 10 corresponding to the display area 101 and the second bending area 1023 are spaced apart from each other, thereby achieving a narrow bezel effect in the corresponding display panel.
[0036] Optionally, the structural portions of the display screen body corresponding to the display area 101 and the second bending area 1023 are arranged parallel to each other at intervals, or they may not be parallel. The specific arrangement can be determined by the spatial layout of the corresponding display device, and this application does not limit this.
[0037] Specifically, the second portion 112 in the array substrate layer 11 is provided corresponding to the first non-bending region 1021, and the array substrate layer 11 also has a third portion (not shown) and a fourth portion (not shown) respectively provided corresponding to the bending region 1022 and the second bending region 1023; and the drive control substrate 13 specifically includes a third sub-part (not shown) and a fourth sub-part (not shown), which are respectively provided on the third portion and the fourth portion, that is, the third portion and the third sub-part are specifically bent corresponding to the bending region 1022, and the fourth portion is provided at a distance from the first portion 111, and the fourth sub-part is provided at a distance from the first sub-part 131.
[0038] In some embodiments, the second sub-part 132 of the drive control substrate 13 is further provided with a groove 1301 at a position away from the first sub-part 131, so as to prevent external moisture from entering the first portion 111 of the array substrate layer 11 in sequence along the second sub-part 132 and the first sub-part 131 in the drive control substrate 13, thereby causing adverse effects on the functional devices and ultimately affecting the display effect.
[0039] Optionally, at least two, such as two, three, or five, reasonably spaced grooves 1301 are specifically provided on the second sub-part 132 of the drive control substrate 13. This is to prevent external moisture from invading into the first part 111 of the array substrate layer 11 along the drive control substrate 13. In addition, when the third sub-part of the drive control substrate 13 is bent, the stress generated by bending can be dispersed to further prevent the array substrate layer 11 from breaking.
[0040] Optionally, the depth of the groove 1301 formed on the second sub-part 132 of the drive control substrate 13 is less than or equal to the thickness of the second sub-part 132. That is, the groove 1301 can be a through groove or a blind groove, and is preferably a through groove, so as to effectively block water vapor that invades into the first portion 111 of the array substrate layer 11 along the second sub-part 132 and the first sub-part 131 in the drive control substrate 13.
[0041] Optionally, the distance between any two adjacent grooves 1301 in at least two grooves 1301 on the second sub-part 132 is equal.
[0042] Optionally, the thickness of the first sub-part 131 of the drive control substrate 13 is greater than or equal to 2 / 3 of the thickness of the second sub-part 132, and less than or equal to 4 / 3 of the thickness of the second sub-part 132, so as to minimize the thickness difference of the array substrate layer 11 at the boundary between the display area 101 and the non-display area 102.
[0043] Preferably, the thickness of the first sub-part 131 of the drive control substrate 13 is equal to the thickness of the second sub-part 132, so as to effectively avoid a large thickness difference in the array substrate layer 11 at the boundary between the display area 101 and the non-display area 102, that is, at the boundary between the first sub-part 111 and the second sub-part 112. This effectively avoids the risk of the array substrate layer 11 breaking due to stress concentration at the boundary when the drive control substrate 13 is bent.
[0044] Optionally, the thickness of the first sub-part 131 of the drive control substrate 13 is less than the thickness of the barrier wall 12, so that the barrier wall 12 can effectively prevent external moisture from entering the first sub-part 111 of the array substrate layer 11 in sequence along the second sub-part 132 and the first sub-part 131 in the drive control substrate 13, thereby adversely affecting the functional devices and ultimately affecting the display effect.
[0045] Preferably, the thickness of the first sub-part 131 of the drive control substrate 13 is less than or equal to 2 / 3 of the thickness of the barrier wall 12 and greater than or equal to 1 / 2 of the thickness of the barrier wall 12, so as to effectively block water vapor that penetrates into the first portion 111 of the array substrate layer 11 along the second sub-part 132 and the first sub-part 131 in the drive control substrate 13.
[0046] In some embodiments, the display body 10 further includes an encapsulation substrate layer 14, which is disposed on a first portion 111 of the array substrate layer 11 and covers the first sub-part 131 and a portion of the second sub-part 132 of the barrier wall 12 and the drive control substrate 13.
[0047] Understandably, the encapsulation substrate layer 14 may also contain designed conductive lines to facilitate electrical connections between different circuits, thereby enabling the corresponding screen display.
[0048] In some embodiments, the display body 10 further includes a touch substrate layer 15, which is specifically disposed on the encapsulation substrate layer 14, a portion of the second sub-part 132, and the groove wall and bottom of the groove 1301.
[0049] Understandably, the touch substrate layer 15 may contain touch electrodes and corresponding conductive circuits to facilitate electrical connections between different circuits, thereby enabling corresponding screen display and touch functions.
[0050] In some embodiments, the display body 10 further includes a cured film protective layer 16, which is specifically disposed on the touch substrate layer 15 and a portion of the second sub-part 132, and wraps the touch substrate layer 15, planarizes the touch substrate layer 15, thereby improving the surface flatness and light transmittance of the display body 10, and provides protection to the outside of the display body 10 to improve its service life.
[0051] In some embodiments, the display body 10 further includes a polarizer 17, which is specifically disposed on the curing film protective layer 16, and the orthographic projection of the polarizer 17 on the array substrate layer 11 covers the entire first portion 111 of the array substrate layer 11, so as to ensure a good display effect of the display body 10.
[0052] This application also provides a display panel; please refer to [link / reference]. Figure 3 , Figure 3 This is a schematic diagram of one embodiment of the display panel of this application. Specifically, the display panel 20 includes: a base layer 21, a display screen body 22, and a cover plate 23 stacked sequentially.

[0054] The base layer 21 is used to provide strength support for the display screen body 22, while the cover plate 23 is specifically used to cover the display screen body 22 to provide protection for the display screen body 22.
[0055] In some embodiments, the display panel 20 further includes an optical adhesive layer (not shown) for bonding the display body 22 to the cover plate 23.
[0056] In some embodiments, the base layer 21 further includes a support film (not shown) and a composite tape (not shown) to connect the display body 22 to the support film via the composite tape.
[0057] This application also provides a display device; please refer to [link / reference].
