Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel and display device. Background Technology

[0002] Currently, with the continuous development of technology, display devices have become an indispensable part of people's lives and production. Due to the advantages of LCD panels such as low power consumption, thin and light size, and good imaging effect, they are widely used in electronic devices such as smartphones, computers, tablets, and televisions.

[0003] High-resolution display panels offer superior display quality. However, as the resolution of display panels increases, the size of their pixel units gradually decreases. Limited by current production capabilities, the sizes of TFTs (Thin Film Transistors) and PSs (Photo Spacers) in display panels cannot be further reduced. To maintain the cell thickness of the display panel, the PS is typically positioned between the BM (Black Matrix) in the CF (Color Film) and the light-shielding layer covering the TFT, using a mutually compensating arrangement to prevent light leakage at the pixel unit edges. Before the display panel leaves the factory, a pressure test is required. When the display panel is pressed, the internal PS is squeezed, causing it to slide relative to the BM. To prevent the PS from sliding out of the BM, the BM needs to have sufficient width. However, as the width of the BM increases, its area also increases accordingly, resulting in a relative decrease in the effective light-transmitting area of ​​the pixel unit. This leads to a reduction in the pixel unit aperture ratio, affecting the display panel's display quality. Summary of the Invention

[0004] In view of this, this application proposes a display panel and a display device to solve the above-mentioned technical problems.

[0005] For the purposes described above, this application provides a display panel, including:

[0006] First substrate;

[0007] The second substrate is located above the first substrate, and the orthographic projection of the second substrate onto the first substrate covers the first substrate;

[0008] A first spacer is disposed on the side of the first substrate close to the second substrate, and the side of the first spacer facing the second substrate abuts against the second substrate, and is configured to maintain the thickness of the display panel;

[0009] A second spacer is disposed on the second substrate, and the second spacer is alternately arranged with the first spacer and configured to prevent the first spacer from sliding.

[0010] Optionally, the height of the first spacer is greater than the height of the second spacer.

[0011] Optionally, at least two of the first spacer and the second spacer are provided.

[0012] Optionally, at least two of the second spacers are arranged in parallel.

[0013] Optionally, the display panel further includes:

[0014] The scanning electrode is disposed on the side of the first substrate close to the second substrate;

[0015] A first light-shielding layer is disposed on the side of the scanning electrode away from the first substrate. The orthographic projection of the first light-shielding layer on the first substrate covers the orthographic projection of the scanning electrode on the first substrate. A first spacer is disposed on the side of the first light-shielding layer away from the first substrate.

[0016] Optionally, the second septum is configured as a strip, and the length direction of the second septum is aligned with the length direction of the scanning electrode.

[0017] Optionally, the display panel further includes:

[0018] A data electrode is disposed on the side of the first substrate near the second substrate, and the data electrode and the scan electrode are arranged crosswise.

[0019] Optionally, the display panel further includes:

[0020] A second light-shielding layer is disposed on the second substrate. The second light-shielding layer is disposed opposite to the first light-shielding layer. The side of the first spacer facing the second substrate abuts against the second light-shielding layer. The second spacer is disposed on the second light-shielding layer.

[0021] Optionally, the orthographic projection of the first spacer on the second light-shielding layer and the orthographic projection of the second spacer on the second light-shielding layer are both located within the second light-shielding layer.

[0022] Based on the same invention, this application also provides a display device, including a display panel as described in any of the above embodiments.

[0023] As can be seen from the above, the display panel and display device provided in this application can block the first spacer that abuts against the second substrate by means of the second spacer on the second substrate, thereby preventing the first spacer from slipping and leaving scratches on the surface of the second substrate when the display panel is pressed, preventing light leakage of the display panel due to PS slippage, and effectively improving the aperture ratio of the pixel unit in the display panel, so that the display panel has a better display effect.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0033] With the continuous development of technology, people have higher and higher requirements for display devices. Due to the advantages of LCD panels such as low power consumption, thin and light size, and good imaging effect, they are widely used in electronic devices such as smartphones, computers, tablets and televisions.

[0034] In related technologies, in order to achieve a better display effect, the display panel needs to have a high resolution. However, as the resolution of the display panel increases, the size of the pixel unit of the display panel will gradually decrease. Due to the current level of technology and manufacturing capabilities, the size of the TFT (Thin Film Transistor) used to drive the pixel unit and the PS used to maintain the cell thickness of the display panel (i.e., the thickness of the liquid crystal layer disposed between the TFT and CF) cannot be further reduced. As a result, the area of ​​the effective light-transmitting area of ​​the pixel unit gradually decreases, leading to a decrease in the light efficiency of the display panel.

[0035] For display panels, the TFTs include Data lines and Gate lines. Both Data and Gate lines are disposed on the substrate of the display panel and are arranged in a staggered manner between adjacent pixel units. The surfaces of Data and Gate lines are typically covered with a light-shielding layer or pixel boundary layer to prevent light leakage at the edges of the pixel units. Furthermore, a CF (Filter Line) is disposed on top of the substrate. The CF includes a BM (Metal Block). During display panel fabrication, the CF needs to be mounted on top of the substrate to prevent light leakage in the display panel. The matrix barrier (BM) on the display cell (CF) is positioned opposite to the light-shielding layer on the substrate. To prevent light leakage at the edges of pixel units caused by the photocell separator (PS) located within the display panel, the PS is positioned between the BM in the CF and the light-shielding layer on the substrate. Typically, the PS can be arranged in a mutually compensating manner, i.e., at the intersection of the data and gate layers, so that the PS is located within the cavity formed between the CF and the substrate, and this cavity is filled with a liquid crystal layer. For example, the PS can employ a columnar support structure or a cross-shaped support structure, enabling the PS to support the interlayer of the display panel and ensuring a stable cell thickness. Please refer to [link to relevant documentation]. Figure 1A and Figure 1B .

[0036] During display panel manufacturing, a mask process can be used to assemble the cell filter (CF) onto the substrate. During assembly, the CF is flattened by rolling to ensure good flatness. Furthermore, before leaving the factory, the display panel undergoes a pressure test, where a certain pressure is applied. Under this pressure, the CF undergoes slight deformation, causing the photocell (PS) to slide relative to the matrix substrate (BM). When the PS moves outside the BM, scratches can easily form in the area outside the BM, such as on the alignment layer of the CF. This hinders the alignment of liquid crystal molecules in the display panel, affecting the display effect. To maintain a stable cell thickness under pressure and prevent the PS from sliding out of the BM and scratching its edges, the width of the BM in the first substrate needs to be widened. However, as the BM width increases, the BM area also expands, leading to a relative decrease in the effective light-transmitting area of ​​the pixel unit, resulting in a lower pixel unit aperture ratio. This affects the display effect and, in severe cases, can even cause display defects.

[0037] In view of this, this application provides a display panel, including a first substrate 100; a second substrate 200, located above the first substrate 100, the orthographic projection of the second substrate 200 onto the first substrate 100 covering the first substrate 100; a first spacer 310, disposed on the side of the first substrate 100 near the second substrate 200, the side of the first spacer 310 facing the second substrate 200 abutting against the second substrate 200, configured to maintain the thickness of the display panel; and a second spacer 320, disposed on the second substrate 200, the second spacer 320 and the first spacer 310 being alternately arranged, configured to prevent the first spacer 310 from sliding. (See also...) Figures 2-4 .

[0038] It should be noted that the display panel includes a first substrate 100 and a second substrate 200, wherein the second substrate 200 is located above the first substrate 100, and the orthographic projection of the second substrate 200 on the first substrate 100 covers the first substrate 100. The first substrate 100 can provide assembly positions for components such as pixel units and first spacers 310, and can support and protect the components disposed between the first substrate 100 and the second substrate 200. Since the second substrate 200 is located above the first substrate 100, a corresponding cavity is formed between the first substrate 100 and the second substrate 200 to accommodate the liquid crystal layer. Since the second spacer 320 is disposed on the side of the second substrate 200 close to the first substrate 100, the second substrate 200 can provide a corresponding assembly area for the second spacer 320.

[0039] Furthermore, the first spacer 310 can be fabricated on the first substrate 100, with one side connected to the surface of the first substrate 100 and the other side abutting against the second substrate 200, allowing the first spacer 310 to be stacked and assembled with the first substrate 100 and the second substrate 200. Simultaneously, the first spacer 310 is located between the first substrate 100 and the second substrate 200 to support them, preventing the display panels from contacting each other under pressure, thus providing adequate space for the liquid crystal and ensuring a stable thickness for the display substrate. The first spacer 320 is provided on the side of the second substrate close to the first substrate. When the display panel is pressed or subjected to pressure, the first spacer 310 supports the two substrates. When the pressure reaches a certain level, the distance between the first substrate 100 and the second substrate 200 is relatively reduced. The second spacer 320 can assist the first spacer 310 in supporting the first substrate 100 and the second substrate 200, thereby improving the support effect between the first substrate 100 and the second substrate 200.

[0040] Correspondingly, within the cavity between the first substrate 100 and the second substrate 200, the first spacer 310 and the second spacer 320 are alternately arranged. During a pressing test or when subjected to external force, the second substrate 200 undergoes a slight deformation and compresses the first spacer 310, causing the side of the first spacer 310 that abuts against the second substrate 200 to slide on the surface of the second substrate 200. At this time, the second spacer 320 intercepts and blocks the first spacer 310, preventing the first spacer 310 from sliding a large distance under the action of external force. On the one hand, this ensures the supporting effect of the first spacer 310 on the first substrate 100 and the second substrate 200, so that the display panel can maintain a stable cell thickness. On the other hand, due to the first spacer 320... Both the first spacer 310 and the second spacer 320 are disposed within the matrix (BM) of the second substrate 200. The second spacer 320 can limit the sliding distance of the first spacer 310 within the BM, preventing the first spacer 310 from leaving scratches on the second substrate 200 due to excessive sliding distance after sliding out of the BM, thus avoiding damage to the display panel and ensuring the quality of the display panel. In addition, compared with existing display panels, the first spacer 310 is always located within the BM under the blocking effect of the second spacer 320 and will not block the pixel unit. Therefore, it is not necessary to widen the width of the BM on the second substrate 200, which can effectively control the area of ​​the BM so that the pixel unit has sufficient effective light transmission area and ensures that the pixel unit has a good aperture ratio, so that the display panel has good light efficiency.

[0041] It should be noted that, in conjunction with existing technology, the first substrate 100 in this application can be configured as a substrate substrate, and the second substrate 200 can be configured as a CF (color filter). Specifically, the substrate substrate in the display panel can include at least one of a PI (polyimide) substrate, a buffer layer, a gate insulating layer, an interlayer dielectric layer, and a planarization layer, ensuring that the substrate substrate has good water and oxygen barrier properties and a support and protection effect. For the CF, the CF can include at least one color resist structure (e.g., red, green, and blue color resist), a BM (metal oxide layer), a planarization layer, and a back-plated metal oxide layer, so that the display panel radiates light of different colors to achieve color display.

[0042] In some embodiments, the height of the first spacer 310 is greater than the height of the second spacer 320. (See also...) Figure 4 .

[0043] It should be noted that since one side of the first spacer 310 is connected to the first substrate 100 and the opposite side abuts against the second substrate, the first spacer 310 can support the first substrate 100 and the second substrate 200, ensuring the stability of the display panel cell thickness. When the display panel is subjected to a pressing test or pressure, the second spacer 320 located on the side of the second substrate 200 close to the first substrate 100 blocks the first spacer 310 from sliding on the second substrate 200, preventing the first spacer 310 from scratching the second substrate 200, thereby achieving control over the BM area on the second substrate 200 and optimizing the aperture ratio of the pixel unit. Specifically, by setting the height of the first spacer 310 to be greater than the height of the second spacer 320, the second spacer 320 can block the first spacer 310 while ensuring that the second spacer 320 will not slip on the first substrate 100 when the display panel is subjected to pressure, thus preventing the second spacer 320 from scratching the first substrate 100 and components such as pixel units located on the first substrate 100; and when the pressing pressure is large, the second spacer 320 will abut and contact the first substrate 100, which can assist the first spacer 310 in supporting the first substrate 100 and the second substrate 200, improving the pressure resistance of the display panel and maintaining a stable cell thickness.

[0044] In some embodiments, at least two of the first spacer 310 and the second spacer 320 are provided. (See also...) Figure 2 and Figure 3 .

[0045] It should be noted that the first spacer 310 is disposed between the first substrate 100 and the second substrate 200, and the first spacer 310 can support the first substrate 100 and the second substrate 200 to maintain the cell thickness of the display panel. The second substrate 200 has a second spacer 320 disposed on the side closest to the first substrate 100, and the two are alternately disposed. Therefore, when the first substrate 100 in the display panel is subjected to pressure, the first spacer 310 against the second substrate 200 will slide relative to the second substrate 200. By arranging the first spacer 310 and the second spacer 320 opposite to each other and alternating their distribution between the first substrate 100 and the second substrate 200, the second spacer 320 can block the sliding first spacer 310 on the second substrate 200, preventing the first spacer 310 from sliding. 310 slides out of the BM in the second substrate 200 and scratches the second substrate 200, without increasing the width and area of ​​the BM, so that the pixel unit has a better aperture ratio; specifically, at least two first spacers 310 and at least two second spacers 320 can be arranged between the first substrate 100 and the second substrate 200 respectively. Each first spacer 310 and each second spacer 320 can be arranged relative to each other. For example, each arrangement area can be provided with two first spacers 310 and two second spacers 320, and the first spacers 310 and the second spacers 320 are alternately distributed so that the first spacers 310 sliding in different directions can be blocked by the second spacers 320, preventing the first spacers 310 at different positions from having a large sliding distance, and improving the pressure resistance of the display panel.

[0046] In some embodiments, at least two second spacers 320 are arranged in parallel between each other. See [link to relevant documentation] Figure 2 and Figure 3 .

[0047] It should be noted that the first spacer 310 and the second spacer 320 are both distributed in the cavity between the first substrate 100 and the second substrate 200. The first spacer 310 supports the first substrate 100 and the second substrate 200 to maintain the cell thickness of the display panel. The second spacer 320 blocks the first spacer 310 from sliding under pressure, preventing it from sliding out of the BM area in the second substrate 200 and scratching the second substrate 200, thus affecting the display effect of the display panel. This allows the width and arrangement area of ​​the BM to be controlled, ensuring that the pixel unit has a good aperture ratio. By arranging the second spacers 320 in parallel on the second substrate 200, it is easier to fabricate multiple second spacers 320 on the second substrate 200, reducing the complexity of display panel manufacturing. At the same time, the multiple second spacers 320 can be arranged in parallel and evenly distributed on the second substrate 200, which can block and intercept the first spacers 310 sliding in different directions in different areas, improving the display panel's ability to resist pressure.

[0048] In some embodiments, the display panel further includes a scanning electrode 410 disposed on the side of the first substrate 100 near the second substrate 200; a first light-shielding layer 500 disposed on the side of the scanning electrode 410 away from the first substrate 100, wherein the orthographic projection of the first light-shielding layer 500 on the first substrate 100 covers the orthographic projection of the scanning electrode 410 on the first substrate 100; and a first spacer 310 disposed on the side of the first light-shielding layer 500 away from the first substrate 100. (See also...) Figure 2 .

[0049] It should be noted that, in this application, the scanning electrode 410 disposed on the first substrate 100 is part of the TFT structure in the display panel and is used as the driving circuit in the pixel unit; and the scanning electrode 410 is covered with a first light-shielding layer 500. The first light-shielding layer covers the first substrate 100 to prevent light leakage in the edge area of ​​the pixel unit. The first spacer 310 is disposed on the first light-shielding layer 500 to prevent interference to the pixel unit, so that the pixel unit has a larger effective light-transmitting area, ensuring the display effect of the display panel. At the same time, it can also effectively support the first substrate 100 and the second substrate 200, so that the display panel has a stable cell thickness.

[0050] In some embodiments, the second septum 320 is configured as an elongated strip, and the length direction of the second septum 320 is aligned with the length direction of the scanning electrode 410. (See also...) Figure 2 and Figure 3 .

[0051] It should be noted that both the first spacer 310 and the second spacer 320 are distributed between the first substrate 100 and the second substrate 200. When the first substrate 100 is subjected to pressure, the first spacer 310 will slide relative to the first substrate 100. The second spacer 320 intercepts and blocks the first spacer 310, preventing scratches from occurring when the first spacer 310 slides on the second substrate 200. By making the second spacer 320 into an elongated shape, the blocking area of ​​the second spacer 320 on the first spacer 310 can be increased, thereby improving the blocking effect of the second spacer 320 on the first spacer 310. The second spacer 320 provides a blocking effect; and when the second spacer 320 is pressed on the display panel, in addition to blocking the first spacer 310, it can also provide auxiliary support for the first substrate 100 and the second substrate 200. Since the second spacer 320 is elongated, its contact area with the first substrate 100 is relatively large, which can improve the interlayer support effect of the second spacer 320. As for the first spacer 310, the first spacer 310 can be set as a columnar spacer 300 or a block spacer 300, both of which can provide good support for the first substrate 100 and the second substrate 200.

[0052] In some embodiments, the display panel further includes data electrodes 420 disposed on the side of the first substrate 100 near the second substrate 200, with the data electrodes 420 and scan electrodes 410 arranged crosswise. (See also...) Figure 2 Specifically, in the display panel, the data electrode 420 disposed on the first substrate 100 is also part of the TFT structure in the display panel, and is used as the driving circuit in the pixel unit. The data electrode 420 and the scan electrode 410 are arranged alternately to form a grid structure on the first substrate 100. The pixel unit is located inside the grid to avoid interference and obstruction of the pixel unit by the scan electrode 410 and the data electrode 420. At the same time, the surfaces of the scan electrode 410 and the data electrode 420 in the TFT can be covered with the first light-shielding layer 500 to avoid light leakage in the edge area of ​​the pixel unit.

[0053] Furthermore, in conjunction with this application, the first light-shielding layer 500 and the staggered scanning electrodes 410 and data electrodes 420 are further described. For the scanning electrodes 410 and data electrodes 420, electrodes arranged on the first substrate 100 in the TFT can be used. The scanning electrode 410 can be the Gate in the TFT to provide the corresponding scanning signal to the TFT, and the data electrode 420 can be the Data in the TFT to provide the corresponding data signal to the TFT, so that the TFT can act as a driving circuit to drive the pixel unit to work. For the first light-shielding layer 500, a light-shielding structure can be used to cover the Gate in the TFT. The material of the first light-shielding layer 500 can be black photoresist or a high optical density material, or a metal layer with reflective effect, to prevent light leakage in the edge area of ​​the pixel unit, and also to avoid crosstalk between adjacent pixel units.

[0054] In some embodiments, the display panel further includes a second light-shielding layer 600 disposed on the second substrate 200. The second light-shielding layer 600 is disposed opposite to the first light-shielding layer 500. A first spacer 310 abuts against the second light-shielding layer 600 on the side facing the second substrate 200. A second spacer 320 is disposed on the second light-shielding layer 600. (See also...) Figure 3 and Figure 4 .

[0055] It should be noted that the second light-shielding layer 600 is disposed on the second substrate 200, and the first spacer 310 and the second spacer 320 are both distributed in the cavity between the first substrate 100 and the second substrate 200. The first spacer 310 supports the first substrate 100 and the second substrate 200 to maintain the cell thickness of the display panel. When the display panel is pressed, the second spacer 320 blocks the sliding first spacer 310, preventing the first spacer 310 from sliding out of the second light-shielding layer 600 in the second substrate 200 and leaving scratches on the second substrate 200. Compared with the existing BM arranged on the CF, this application does not require widening the space. The second light-shielding layer 600 on the second substrate 200 can effectively control the width and arrangement area of ​​the second light-shielding layer 600, thereby giving the pixel unit a better aperture ratio. In addition, the second light-shielding layer 600 disposed on the second substrate 200 is disposed opposite to the first light-shielding layer 500 disposed on the first substrate 100. The first spacer 310 and the second spacer 320 are both located between the first light-shielding layer 500 and the second light-shielding layer 600. Therefore, the second light-shielding layer 600 can absorb or block the light transmitted through the second substrate 200, preventing the first substrate 100 from having problems such as light leakage and color confusion, and effectively improving the contrast of the display panel.

[0056] In contrast, further explanation of the second light-shielding layer 600 in conjunction with this application: the second light-shielding layer 600 is disposed on the second substrate 200, and the first spacer 310 abuts against the second light-shielding layer 600 on the side facing the second substrate 200. The second spacer 320 is disposed on the second light-shielding layer 600. Therefore, the second light-shielding layer 600 in this application can be the BM in the CF. The BM can isolate different sub-color units in the CF, so that it can filter stray light passing through the CF layer and avoid display problems such as light leakage and color confusion. When the first spacer 310 slides on the BM on the second substrate 200, it is blocked by the second spacer 320 and the first spacer 310 is always located inside the BM. Therefore, without widening the width of the second light-shielding layer 600 and increasing its area, the first spacer 310 can always be located inside the second light-shielding layer 600 and will not interfere with the light transmission of the pixel unit, so that it has a better aperture ratio.

[0057] In some embodiments, the orthographic projection of the first spacer 310 onto the second light-shielding layer 600 and the orthographic projection of the second spacer 320 onto the second light-shielding layer 600 are both located within the second light-shielding layer 600. (See also...) Figure 3 and Figure 4 .

[0058] It should be noted that the second light-shielding layer 600 is disposed on the second substrate 200 relative to the first light-shielding layer 500. Both the first spacer 310 and the second spacer 320 are located within the cavity between the first substrate 100 and the second substrate 200. The second spacer 320 blocks the first spacer 310 from sliding under pressure, preventing it from sliding out of the second light-shielding layer 600 and scratching the second substrate 200. Simultaneously, it effectively controls the width and area of ​​the second light-shielding layer 600, ensuring the pixel unit has a good aperture ratio. Furthermore, by ensuring that the orthographic projections of the first spacer 310 and the second spacer 320 onto the second light-shielding layer 600 are both within the second light-shielding layer 600, it is possible to ensure that the first spacer 310 provides adequate support for the first substrate 100 and the second substrate 200. The first spacer 310 and the second spacer 320 provide support and prevent them from obstructing the pixel units. Furthermore, when the display panel is subjected to pressure during a press test or external pressure, the first spacer 310, which rests against the second light-shielding layer 600, will slide relative to the surface of the second light-shielding layer 600. Since the first spacer 310 can be blocked by the second spacer 320, it is possible to prevent the first spacer 310 and the second spacer 320 from interfering with the light transmission capability of the pixel units, thus improving the display effect of the display panel. Additionally, even if the first spacer 310 develops corresponding scratches on the second light-shielding layer 600 due to sliding, the corresponding position on the second substrate 200 will not show the scratches because the second light-shielding layer 600 has a shielding effect, ensuring that the display panel has a good display effect.

[0059] For example, during the pressing test before the display panel leaves the factory, pressure is applied to the second substrate 200 of the display panel to cause slight deformation. At this time, some areas of the first spacer 310 in the display panel slide relative to the second light-shielding layer 600. The first spacer 310 in this area moves closer to the second spacer 320 until the first spacer 310 contacts and blocks the second spacer 320. At this time, due to the blocking effect of the second spacer 320, the first spacer 310 will not slide off the second light-shielding layer 600 and leave scratches on the surface of the second substrate 200; at the same time, some areas of the first spacer 310... The second light-shielding layer 600 is far from the second spacer 320. Since the first spacer 310 and the second spacer 320 are alternately arranged inside the cavity, the other set of first spacers 310 and second spacers 320 will approach each other, and the second spacer 320 in the other set will block the first spacer 310, preventing the first spacer 310 in this area from sliding out of the second light-shielding layer 600 and causing scratches on the surface of the second substrate 200. This ensures the light transmission effect of the pixel unit, and at the same time, there is no need to increase the width and arrangement area of ​​the second light-shielding layer 600, so that the aperture ratio of the pixel unit can be optimized and the display panel can have a better display effect.
