Description

Technical Field

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

[0002] With the continuous development of display technology, in-cell touch technology has been widely used in thin-film transistor liquid crystal display (TFT-LCD) panels due to its advantages such as making screens thinner and lighter and better display effects. In-cell touch technology integrates touch functionality directly into the pixel structure of the display panel. For example, it reuses a common electrode (VCOM) as a touch sensor, and each touch electrode block needs to be independently connected to the touch signal line through a touch hole.

[0003] In existing technologies, to meet color gamut specifications, the red (R), green (G), and blue (B) color resists on the color filter (CF) side are typically designed with different thicknesses, resulting in a step difference between the RGB film layers. To ensure the support stability of the pillar spacers (PS), it is necessary to ensure that the PS can stand on a single color resist layer, avoiding problems such as uneven PS top contours and reduced actual support area caused by standing at the RGB overlap. Therefore, some products employ a design where the RGB color resist shape is adjusted to a single-sided protrusion at the Gate Black Matrix (GBM) location to ensure that the PS has a stable single color resist support surface.

[0004] However, while this existing RGB color filter design achieves optimized PS support, it introduces new problems. For example... Figure 1 As shown, the smaller square represents the touch via, and the larger rectangle represents the columnar spacer. The overlapping area of ​​the RGB color resist protrusions is too close to the touch via on the TFT side, even causing interference. Considering process variations, to ensure that the black matrix (BM) effectively encapsulates the color resist to prevent light leakage, the distance between the overlapping area of ​​the RGB color resist and the touch via is typically only about 1μm. This tiny distance, along with the uneven surface of the RGB overlapping area, has a serious negative impact on the transmission and detection of touch signals, specifically manifested as follows: Inconsistent signal transmission delay: Touch vias are critical nodes connecting touch electrodes and touch signal lines, and are filled with a transparent conductive material (usually indium tin oxide, ITO). When the overlapping area of ​​the RGB color resist is too close to the touch via, the uneven topography of the overlapping area affects the deposition morphology of the conductive material at the touch via, resulting in inconsistent current path lengths within the conductive material. This difference causes a deviation in the arrival time of electrical signals from different touch vias on the same touch scan line to the TDDI chip, resulting in signal timing misalignment. In multi-touch scenarios, this timing misalignment can cause the chip to fail to accurately identify the coordinates of multiple touch points, leading to touch positioning errors or touch trajectory drift.

[0005] Uneven capacitive coupling: The uneven topography of the overlapping RGB color resist areas alters the dielectric environment around the touch vias. Specifically, in the raised RGB areas, the equivalent distance between the touch via and the sensing electrode increases, resulting in an uneven distribution of the coupling capacitance between the touch electrode and the finger. In the raised areas, the capacitance change (ΔC) is significantly smaller compared to the flat areas, leading to decreased touch sensitivity in these areas. This requires the user to apply greater pressure to trigger a response, severely impacting the touch experience. This problem of uneven capacitive coupling is particularly prominent in large-size display panels because the touch signals of large-size panels are inherently weaker and more susceptible to interference from environmental factors.

[0006] Crosstalk between touch vias: Interference between touch vias and the overlapping RGB regions can cause abnormal liquid crystal anchoring orientation in that area. Changes in the anchoring orientation of liquid crystal molecules affect the voltage stability of the common electrode (VCOM), leading to increased VCOM voltage fluctuations. Since touch detection is typically based on capacitance changes, these VCOM voltage fluctuations are superimposed on the touch signal, creating additional interference. This interference not only affects the signal-to-noise ratio of the touch signal but may also be misinterpreted as a touch signal by the TDDI chip, leading to false triggers, or generate noise during touch detection, reducing the accuracy and stability of touch recognition.

[0007] Furthermore, interference issues between RGB color resist overlap and touch vias can also lead to other optical and electrical defects. For example, the interference area can become a source of liquid crystal alignment disorder, resulting in dark lines or bright spots when displaying images; the uneven surface of the interference area may cause uneven coating of the subsequent alignment film (PI), further exacerbating display unevenness. These problems are particularly important to avoid in high-end display products, as consumers have increasingly higher demands for display quality and touch experience.

[0008] In summary, the RGB color resist structure designed in the prior art to meet the requirements of PS support suffers from interference due to its close proximity to the touch via, leading to a series of touch signal quality degradation problems and severely affecting the overall performance of the display panel. Therefore, how to effectively avoid interference between the RGB color resist structure and the touch via while ensuring the stability of PS support, thereby improving touch signal quality, has become an urgent technical challenge to be solved in this field. Summary of the Invention

[0009] In view of this, embodiments of the present invention provide a display panel and a display device to optimize touch signal quality while ensuring PS support performance, thereby improving the overall performance and reliability of the display panel.

[0010] Therefore, the present invention provides a display panel including an array substrate and a color filter substrate disposed opposite to each other, wherein the array substrate includes touch signal lines and touch vias electrically connected to the touch signal lines; The color filter substrate includes a black matrix and multiple color resist blocks; Wherein, in a direction perpendicular to the display panel, the color resist block at least partially overlaps with the black matrix; The via is projected onto the array substrate and lies within the projection of the black matrix onto the array substrate. The via is also projected onto the array substrate and lies within the projection of the color resist block onto the array substrate. The color resist block has a raised overlapping structure at the via within the projection of the array substrate. The via is projected onto the array substrate and lies within the projection of the raised overlapping structure onto the array substrate.

[0011] In one possible implementation, the display panel further includes columnar spacers disposed on the color filter substrate, wherein the orthographic projection of the columnar spacers on the color filter substrate overlaps with a single color resist block.

[0012] In one possible implementation, the touch vias are alternately distributed on the array substrate along a first direction, and the protrusion direction of the overlapping protrusion structure of the color resist is opposite to the alternation direction of the touch vias.

[0013] In one possible implementation, when the touch via is located to the right of the touch signal line it is located on, the overlapping structure of the color resist block where the touch via is located protrudes to the left.

[0014] In one possible implementation, when the touch via is located to the left of the touch signal line it is located on, the overlapping structure of the color resist block containing the touch via protrudes to the right.

[0015] In one possible implementation, in areas where no touch vias or columnar spacers are provided between adjacent color resist blocks, there are no protruding overlapping structures between adjacent color resist blocks, and the edges of adjacent color resist blocks are flush with each other.

[0016] In one possible implementation, the overlapping structure of the protrusions is formed by two adjacent color resist blocks among the plurality of color resist blocks interlocking in the region where the black matrix is ​​located through mutually matching protrusions and depressions.

[0017] In one possible implementation, the horizontal projection distance between the protruding overlapping structure edge of the color resist block and the touch via is greater than or equal to the minimum process size of the color resist wrapped by the black matrix.

[0018] In one possible implementation, the touch vias are arranged periodically on the array substrate, and the relative position and spacing between each touch via and its adjacent gate line, data line and active layer are the same.

[0019] On the other hand, embodiments of the present invention also provide a display device, including the display panel described in the above embodiments.

[0020] The beneficial effects of the embodiments of the present invention are as follows: The present invention provides a display panel and display device, which redesigns the RGB color filter structure of the color filter layer. This novel RGB color filter design has the following beneficial effects: 1. Good support stability: By setting the overlapping structure of RGB color resists away from the touch via, it can be ensured that the columnar spacers can still stand stably on the single color resist layer, ensuring the flatness and support density of the PS top surface, thereby maintaining the uniformity of the LCD cell thickness and improving the mechanical stability and display uniformity of the display panel.

[0021] 2. Excellent Touch Performance: The overlapping structure of the RGB color resistors is designed opposite to the position of the touch via, effectively increasing the distance between them and completely avoiding interference problems that may be caused by process variations. This results in a flatter deposition environment for the conductive material at the touch via, ensuring the consistency of the signal transmission path, reducing the risk of uneven capacitive coupling and signal crosstalk, improving touch sensitivity and positioning accuracy, and enhancing the quality and reliability of the touch signal.

[0022] 3. High process compatibility: The technical solution of this invention is achieved by changing the mask pattern of the RGB color resist, without the need to add a new photomask or change the existing process flow. It has extremely high process compatibility and cost advantages, and is easy to promote and apply on existing production lines.

[0023] 4. High design flexibility: This invention provides different RGB color resist design strategies for different areas (areas with touch vias and PS, and areas without touch vias and PS), which not only ensures the performance requirements of key areas, but also simplifies the graphic structure of non-critical areas, achieving an optimized balance between performance and process.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0026] Unless otherwise defined, the technical or scientific terms used in the embodiments of this invention shall have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in the embodiments of this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0027] The size and shape of each component area in the attached drawings do not reflect the actual proportions of each component; they are only intended to illustrate the content of this invention.

[0028] This embodiment provides a display panel, which includes an array substrate and a color filter substrate disposed opposite to each other.

[0029] The array substrate includes a substrate, multiple gate lines and multiple data lines disposed on the substrate, multiple pixel regions defined by the intersection of the gate lines and data lines, thin-film transistors disposed in each pixel region, a common electrode layer, touch signal lines, and touch vias 1 electrically connected to the touch signal lines, such as... Figure 2 As shown. The touch via 1 penetrates the insulating layer and is used to electrically connect the touch electrode (which can be multiplexed from a common electrode block) to the touch signal line. For the sake of simplicity, the other components are not shown except for the touch via 1.

[0030] The basic principle of In-cell Touch technology is to embed the touch sensor directly into the pixel structure of the display panel, rather than attaching the touch module to the outside of the display panel as in out-cell or on-cell technologies. In thin-film transistor liquid crystal displays (TFT-LCDs), In-cell Touch technology typically reuses the display's common electrode (VCOM) as the touch sensor, dividing the originally continuous common electrode into multiple independent touch electrode blocks. Each touch electrode block needs to be independently connected to a touch signal line, and the electrical connection between the touch electrode and the touch signal line is achieved through a touch hole. When a finger touches the screen, it changes the coupling capacitance between the touch electrode and the finger at the corresponding location. The Touch and Display Driver Integration (TDDI) chip identifies the touch location by detecting the change in capacitance.

[0031] In this technical architecture, the design of the placement of touch vias is crucial. To ensure the uniformity and accuracy of touch detection, touch vias typically need to meet the following design principles: First, the touch vias need to match the distribution of the gate lines, data lines, and active layer to ensure that the coupling capacitance between each touch electrode block and the surrounding signal lines remains consistent, avoiding uneven touch signals due to differences in coupling capacitance; Second, touch vias need to be distributed alternately from left to right to avoid all via locations being concentrated in the same area, preventing short-circuit risks caused by local thinning of the insulating layer; Third, touch vias need to be evenly distributed to ensure that the connection points between each column of touch electrodes and touch lines are evenly distributed, improving the consistency of touch detection. Based on the above design principles, in actual products, touch vias 4 are typically distributed alternately from left to right along the extension direction of the touch signal lines on the array substrate 1 to ensure consistency with the coupling capacitance between the gate lines, data lines, and active layer, and to achieve uniform via distribution.

[0032] In this embodiment, for a single touch signal line, the touch vias 1 are alternately distributed left and right between adjacent columns (e.g., Figure 2 As shown, this ensures consistency in the coupling capacitance with the gate line, data line, and active layer, and achieves uniform via distribution.

[0033] The color filter substrate includes a transparent substrate, a black matrix formed on the transparent substrate, multiple color resist blocks, and columnar spacers. The multiple color resist blocks include at least red (R), green (G), and blue (B) color resists, which are arranged on the transparent substrate according to a preset pattern (e.g., strip arrangement or mosaic arrangement), with adjacent color resist blocks separated by the black matrix. The black matrix is ​​disposed in the gaps between the color resist blocks and in the areas corresponding to gate lines and data lines to prevent light leakage and improve display contrast.

[0034] In the Gate Black Matrix (GBM) region, to ensure that the columnar spacers can stand upright on a single color resist, this application designs the shape of the RGB color resist: in a direction perpendicular to the display panel, the color resist block at least partially overlaps with the black matrix. The orthographic projection of the touch via 1 onto the array substrate lies within the orthographic projection of the black matrix onto the array substrate, and the orthographic projection of the touch via 1 onto the array substrate lies within the orthographic projection of the color resist block onto the array substrate. The touch via 1 has a raised overlapping structure 2 at the point where the color resist block is projected onto the array substrate. The raised overlapping structure 2 is oriented away from the touch via 1.

[0035] In some embodiments, the overlapping raised structure 2 is formed by two adjacent color resist blocks from a plurality of color resist blocks fitting together in the region where the black matrix is ​​located through matching protrusions and recesses. Specifically, the overlapping raised structure 2 is formed by fitting two adjacent red, green, and blue color resist blocks together in the region where the black matrix is ​​located. The edge shapes of the two adjacent color resist blocks match each other. One color resist block has an extension structure protruding towards the other color resist block, and the other color resist block has a recessed structure that accommodates the extension structure. The two fit together to form the overlapping raised structure. The core of this invention is that by designing the mask pattern, the direction of this overlapping raised structure is opposite to the position direction of the touch via, thereby increasing the distance between the two in physical space.

[0036] The columnar spacer 3 is disposed on the color filter substrate, and the orthographic projection of the columnar spacer 9 on the color filter substrate overlaps with the single color resist block. This arrangement ensures that the columnar spacer stands stably on the flat single color resist layer, avoiding problems such as uneven top contours and reduced actual support area caused by standing in the overlapping color resist area. This ensures the flatness of its top surface and support density, maintaining the uniformity of the liquid crystal cell thickness. The height of the columnar spacer can be set according to the design requirements of the liquid crystal cell thickness, typically between 2μm and 4μm.

[0037] In this invention, the protrusion direction of the overlapping structure of the color resist blocks is related to the alternating direction of the touch vias. This correlation design makes the structure of the entire display panel more coordinated and unified, which is beneficial for process implementation and performance optimization. In some embodiments, the touch vias are distributed alternately left and right along a first direction on the array substrate, and the protrusion direction of the overlapping structure of the color resist blocks is opposite to the alternating direction of the touch vias. Specifically, when a touch via is located on one side of a touch signal line at a certain position, the corresponding RGB color resist protrusion overlapping structure is located on the other side of the touch signal line, thereby ensuring that the two are always in a relatively far apart state.

[0038] As a specific implementation, when the touch via is located to the right of the touch signal line it is on, the overlapping structure of the RGB color resist blocks containing the touch via protrudes to the left. With this design, the protruding overlapping structure of the RGB color resists is located to the left of the touch signal line, while the touch via is located to the right of the touch signal line. The two are separated by at least the linewidth of the touch signal line, and with the spacing on both sides, interference can be effectively avoided.

[0039] As another specific implementation, when the touch via is located to the left of the touch signal line it is located on, the overlapping structure of the color resist block containing the touch via protrudes to the right. This design is symmetrical to the above implementation and can also achieve the technical effect of keeping the protruding overlapping structure away from the touch via.

[0040] In some embodiments, the horizontal projection distance between the overlapping protrusions of the color resist block and the touch via is greater than or equal to the minimum process dimension of the color resist wrapped by the black matrix. This minimum process dimension refers to the minimum single-sided width of the black matrix edge exceeding the color resist edge, designed to ensure the black matrix effectively blocks the color resist edge and prevents light leakage during display panel manufacturing. In actual manufacturing, the minimum process dimension of the black matrix wrapping the color resist is typically 4 μm. This is to ensure that the black matrix can still effectively cover the color resist edge and prevent light leakage even under process fluctuations such as exposure alignment deviations. By setting the distance between the overlapping protrusions and the touch via greater than or equal to this minimum process dimension, it can be ensured that even under the most unfavorable process fluctuation conditions, the two will not interfere with each other, thereby guaranteeing the stability and reliability of the touch signal.

[0041] In some embodiments, the touch vias are periodically arranged on the array substrate. Each touch via has the same relative position and spacing with its adjacent gate line, data line, and active layer, ensuring consistent coupling capacitance between each touch via and its corresponding gate line, data line, and active layer. This uniform distribution helps ensure the uniformity and stability of the touch signal, avoiding uneven touch signal due to differences in coupling capacitance. Specifically, the touch vias are typically located near the intersection of gate lines and data lines, and their relative position with the active layer is consistent, ensuring that the parasitic capacitance of each touch via is substantially the same as that of the surrounding signal lines.

[0042] This embodiment provides another display panel structure, the structure of which can be referred to. Figure 3 This embodiment mainly targets areas in the display panel that do not have touch vias or columnar spacers.

[0043] In these areas, since there's no need to consider the selection of PS support points or worry about interference between the touch vias and the overlapping RGB structures, the shape of the RGB color resistors can be simplified. For example... Figure 3 As shown, for such areas, the color resist protrusions that were originally used to ensure the PS position are removed, and the edges of adjacent green color resists (G) and blue color resists (B) (or other color resist combinations) are aligned.

[0044] This design simplifies the color resist pattern and reduces unnecessary irregular structures, thereby increasing the process margin and reducing process risks (such as development residue and poor peeling) caused by the complexity of the color resist pattern. At the same time, the planarization design in this area also helps to improve the display uniformity of the entire panel.

[0045] In this embodiment, there is no protruding overlapping structure between adjacent color resist blocks, and the edges of adjacent color resist blocks are flush with each other, forming a roughly straight boundary line. This helps to simplify mask design and improve production efficiency and yield.

[0046] In summary, this invention, by innovatively adjusting the overlap direction of RGB color resists at key locations (such as Gate BM) and simplifying the design of non-critical areas, effectively solves the problem of interference between the RGB structure and touch vias while ensuring display performance and mechanical support. This significantly improves the touch signal quality and reliability of embedded touch panels. Furthermore, this invention requires no additional photomasks or processing steps, making it promising for industrial applications.
