Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a display panel and display device. Background Technology

[0002] With the rapid development of Virtual Reality (VR) technology, the requirements for display panels in terms of resolution, color performance, and image clarity are constantly increasing. Especially in VR LCD display panels with ultra-high pixel density (Pixels Per Inch, PPI), due to the significant reduction in pixel size, the optical isolation space between different sub-pixels is compressed, making it easier for light to overflow and crosstalk between adjacent sub-pixels. This can lead to problems such as color bleeding, impure colors, or decreased contrast in the displayed image, affecting the overall visual effect and immersion.

[0003] In existing technologies, to reduce color crosstalk, the optical isolation capability between subpixels is typically improved by optimizing color resist materials, adjusting the black matrix layout, or increasing the height of the optical isolation structure between subpixels. However, when panels adopt ultra-high pixel density architectures, the effective isolation distance between subpixels is difficult to increase further due to limitations in manufacturing processes, reduced linewidth, and lithographic resolution, making it still difficult to effectively suppress optical crosstalk.

[0023] Please combine Figure 1 and Figure 2 This embodiment provides a display panel 1, which may include, but is not limited to, a liquid crystal display (LCD) panel. The organic light-emitting diode (OLED) display panel 1 has advantages such as self-illumination, thin structure, fast response speed and high contrast, and is therefore suitable for virtual reality (VR) devices to meet the display requirements of virtual reality devices for thinness, high refresh rate and high pixel density.

[0024] The display panel 1 includes a first substrate 10 and a second substrate 20 disposed opposite to each other, and a liquid crystal layer located between the first substrate 10 and the second substrate 20; wherein the first substrate 10 and the second substrate 20 are sealed to form a liquid crystal cell to accommodate the liquid crystal layer, the liquid crystal layer includes a plurality of liquid crystal molecules, and the arrangement state of the liquid crystal molecules changes the light transmittance as the electric field between the two substrates changes to achieve display.

[0025] The display panel 1 adopts a structure in which a color filter layer 16 is integrated on an array substrate (COA); wherein, the first substrate 10 can be an array substrate, and the color filter layer 16 is directly disposed on the side of it facing the second substrate 20, so that the color filter layer 16 is arranged on the same side as the array driving circuit; the second substrate 20 is a counter substrate, used to cover the liquid crystal layer together with the first substrate 10.

[0026] Furthermore, the display panel 1 includes a pixel electrode layer 18 and a common electrode layer 111, and both the pixel electrode layer 18 and the common electrode layer 111 can be disposed on the first substrate 10; wherein, the pixel electrode layer 18 serves as a partition electrode driven by a corresponding thin film transistor 141, and is used to apply a driving signal to each pixel unit; while the common electrode layer 111 is disposed in the upper structure of the first substrate 10, and can form a continuous common electrode surface, which together with the pixel electrode layer 18 forms a vertical electric field or a lateral electric field to regulate the orientation of liquid crystal molecules in the corresponding region.

[0027] Specifically, the first substrate 10 includes a first substrate 11, a light-shielding layer 12 disposed on the first substrate 11, a buffer layer 13 disposed on the side of the light-shielding layer 12 away from the first substrate 11, a thin film transistor layer 14 disposed on the first substrate 11, a dielectric layer 15 disposed on the side of the thin film transistor layer 14 away from the first substrate 11, a color filter layer 16 disposed on the side of the dielectric layer 15 away from the thin film transistor layer 14, a first insulating layer 17 disposed on the side of the color filter layer 16 away from the dielectric layer 15, a pixel electrode layer 18 disposed on the side of the first insulating layer 17 away from the color filter layer 16, a second insulating layer 110 disposed on the side of the pixel electrode layer 18 away from the first insulating layer 17, a common electrode layer 111 disposed on the side of the second insulating layer 110 away from the pixel electrode layer 18, and a third insulating layer 112 disposed on the side of the common electrode layer 111 away from the second insulating layer 110.

[0028] The first substrate 11 is used to carry and support the thin film structure of each layer of the first substrate 10, providing overall mechanical stability and preventing deformation during subsequent deposition or encapsulation. The first substrate 11 can be a rigid substrate or a flexible substrate. When the first substrate 11 is a rigid substrate, its material can be a material with excellent mechanical strength and thermal stability, such as metal or glass. When the first substrate 11 is a flexible substrate, its material can include at least one of acrylic resin, methacrylic resin, polyisoprene, vinyl resin, epoxy resin, polyurethane-based resin, cellulose resin, silicone resin, polyimide-based resin, and polyamide-based resin to meet the requirements of flexible devices for bending and mechanical compliance.

[0029] The thin-film transistor layer 14 is used to control the on and off of the corresponding pixel electrode 181, thereby realizing precise driving of liquid crystal molecules and image display. The thin-film transistor layer 14 may include multiple thin-film transistors 141, which may be etch-block type, back-channel etch type, or classified into bottom-gate thin-film transistors 141, top-gate thin-film transistors 141, etc., according to the position of the gate 1413 and the active layer. This embodiment does not limit this.

[0030] Specifically, the thin-film transistor 141 may include a semiconductor layer 1411, a gate insulating layer 1412, a gate 1413, an interlayer insulating layer 1414, a first electrode 1415, and a second electrode 1416 stacked on the buffer layer 13; wherein, one of the first electrode 1415 and the second electrode 1416 is the source, and the other of the first electrode 1415 and the second electrode 1416 is the drain, the first electrode 1415 is electrically connected to one end of the semiconductor layer 1411, and the second electrode 1416 is electrically connected to the other end of the semiconductor layer 1411; it is understood that this embodiment only uses a top-gate thin-film transistor 141 as an example to illustrate the technical solution of this utility model.

[0031] The orthographic projection of the light-shielding layer 12 on the first substrate 11 covers the orthographic projection of the semiconductor layer 1411 on the first substrate 11. The light-shielding layer 12 can block the light incident on the semiconductor layer 1411, thereby reducing the increase in leakage current caused by photogenerated carriers generated by light irradiating the semiconductor layer 1411, and thus maintaining the stability of the display panel 1 during operation.

[0032] The color filter layer 16 includes a color resist layer 161, which includes a plurality of separately disposed color resist blocks 1611. The spacing between any two adjacent color resist blocks 1611 along the length or width direction of the display panel 1 is equal, making the distribution of each color resist block 1611 on the first substrate 11 more uniform. This improves the consistency of each color resist block 1611 in the thickness and horizontal directions, reduces the impact of edge shrinkage or photolithography deviation on the final color resist pattern, and further ensures the stability of the optical aperture size of different color sub-pixels.

[0033] Specifically, the plurality of color blocks 1611 include, but are not limited to, red color blocks, green color blocks and blue color blocks, used to selectively transmit incident white light to obtain red, green and blue primary color light.

[0034] Furthermore, the second electrode 1416 is disposed in the same layer as the color resist layer 161, and the second electrode 1416 is located between two adjacent color resist blocks 1611 and spaced apart from the color resist blocks 1611. By placing the second electrode 1416 between two adjacent color resist blocks 1611, the driving signal can be extracted without occupying the effective light-transmitting area, thereby avoiding the second electrode 1416 from encroaching on the optical opening area and improving the effective light transmittance of the pixel.

[0035] Meanwhile, the second electrode 1416 is spaced apart from the two adjacent color resist blocks 1611, which can ensure that there is a sufficient separation distance between the color resist blocks 1611 of different colors, so as to prevent color bleeding or color transfer between the color resist blocks 1611 of different colors, and improve the color purity and display accuracy of the display panel 1.

[0036] Specifically, the second electrode 1416 is a transparent electrode. By setting the second electrode 1416 as a transparent electrode, light can be ensured to pass through the area between the pixel electrode 181 and the liquid crystal layer, thereby not affecting the effective light transmittance of the display panel 1. The transparent electrode can be made of materials such as indium tin oxide, indium zinc oxide, or indium tin zinc oxide, so that the second electrode 1416 has high optical transmittance while ensuring conductivity, further improving the color purity, brightness uniformity, and image quality of the display panel 1.

[0037] The first insulating layer 17 can be a first planarization layer. The first insulating layer 17 covers the second electrode 1416 and the color resist layer 161, and fills the gap between the adjacent color resist blocks 1611 and the second electrode 1416. By forming the first planarization layer on the second electrode 1416 and the color resist layer 161, the underlying film layer can be fully covered, thereby smoothing the height difference and sidewall morphology of the color resist layer 161 after photolithography, and eliminating surface non-uniformity caused by the gaps between the color resist blocks 1611, the thickness variation of the second electrode 1416, or pattern steps.

[0038] Meanwhile, the first planarization layer fills the surface gaps and forms a smooth interface, which can ensure the uniform deposition of the subsequent pixel electrode layer 18, stabilize the electric field distribution in the pixel area, thereby improving the optical uniformity of the display panel 1 and enhancing the display performance and brightness uniformity of the display panel 1.

[0039] Specifically, the first insulating layer 17 has a first via 171 corresponding to the second electrode 1416; the pixel electrode layer 18 includes a plurality of pixel electrodes 181, each pixel electrode 181 is disposed corresponding to one thin film transistor 141, and the pixel electrode 181 extends along the inner wall of the first via 171 to above the second electrode 1416 and is electrically connected to the second electrode 1416, thereby making the pixel electrode 181 electrically connected to the semiconductor layer 1411 through the second electrode 1416, realizing effective pixel driving.

[0040] It is understood that by extending the pixel electrode 181 along the inner wall of the first via 171 and electrically connecting it to the second electrode 1416, the electrical connection between the pixel electrode 181 and the thin-film transistor 141 can be completed without increasing the additional space of the first substrate 10, ensuring that the pixel electrode 181 can obtain a stable driving current.

[0041] It should be noted that the display panel 1 further includes a second planarization layer 19, which is disposed on the side of the pixel electrode 181 away from the first substrate 11, and fills the first via 171, thereby providing a flat support interface when the pixel electrode 181 crosses the first via 171, reducing stress concentration of the pixel electrode 181 at the edge of the first via 171, and avoiding open circuit defects caused by local warping or breakage of the pixel electrode 181.

[0042] The second insulating layer 110 can be a passivation layer. The second insulating layer 110 covers the pixel electrode layer 18, providing protection for the pixel electrode layer 18 and preventing short circuits, leakage, or abnormal local resistance of the pixel electrode 181, thereby improving the electrical performance stability and reliability of the display panel 1.

[0043] Meanwhile, the second insulating layer 110 can fill the tiny gaps between the pixel electrodes 181 to form a smooth and continuous surface, ensuring uniform deposition and stable adhesion of subsequent layers, improving the uniformity of liquid crystal molecule arrangement, reducing brightness differences or image distortion caused by uneven local electric fields in the display panel 1, and improving the display uniformity and image quality of the display panel 1.

[0044] The third insulating layer 112 can be a third planarization layer, which covers the common electrode layer 111. The third planarization layer is used to provide a smooth surface, eliminate the step difference and unevenness on the surface of the common electrode layer 111, so that the film layers formed subsequently (such as support pillars 30, alignment layers, etc.) can be deposited uniformly and stably on the third insulating layer 112, thereby improving the film quality and structural stability of subsequent processes.

[0045] Furthermore, the display panel 1 also includes a support post 30 disposed between the first substrate 10 and the second substrate 20; the second substrate 20 includes a second base 21; one end of the support post 30 contacts the second base 21, and the other end of the support post 30 contacts the third insulating layer 112, thereby providing structural support while maintaining a uniform gap between the first substrate 10 and the second substrate 20, and preventing the liquid crystal cell from deforming or collapsing during encapsulation or external stress.

[0046] Specifically, the color resist layer 161 does not have a light-shielding portion on the side away from the first substrate 10, and the second substrate 21 does not have a black matrix 22 on the side close to the first substrate 10, thereby increasing the pixel aperture ratio and reducing the manufacturing cost and process complexity of the display panel 1.

[0047] It should be noted that in related technologies, a light-shielding portion formed of a light-shielding material is typically provided on the side of the first substrate 10 near the second substrate 20, or a black matrix formed of a light-shielding material is provided on the side of the second substrate 20 near the first substrate 10, thereby blocking light leakage between two adjacent color blocks 1611 to reduce color bleeding or color diffusion. However, the light-shielding portion and the black matrix not only occupy a large amount of non-transparent area and limit the pixel aperture ratio, but also require additional photomask processing, further increasing the manufacturing cost and process complexity of the display panel 1.

[0048] It is understood that by not providing a light-shielding part 113 on the side of the first substrate 10 near the second substrate 20, and not providing a black matrix 22 on the side of the second substrate 20 near the first substrate 10, the support post 30 directly contacts the second substrate 21 and the third insulating layer 112, thus avoiding the pixel aperture ratio limitation problem caused by the light-shielding part 113 and the black matrix 22 in the related art, while simplifying the manufacturing process of the display panel 1 and reducing the manufacturing cost.

[0049] Please combine Figure 1 and Figure 3 In one embodiment, the display panel 1 further includes a circular polarizer 40, which is disposed on the side of the second substrate 20 away from the first substrate 10. The circular polarizer 40 is used to adjust the polarization state of the transmitted light and includes a linear polarizing layer and a phase retardation layer. By converting linearly polarized light into circularly polarized light, the reflection characteristics of light and display uniformity are improved.

[0050] It is understood that, compared with the linear polarizers used in related technologies, the circular polarizer 40 can effectively suppress the reflection of external ambient light, improve the display contrast of the display panel 1, and reduce glare; at the same time, it improves the optical performance of liquid crystal molecules under high refresh rate or wide viewing angle conditions. Furthermore, the circular polarizer 40 can also reduce image ghosting and optical color mixing in virtual reality display applications, improving the overall color purity and visual comfort of the image.

[0051] Please combine Figure 1 , Figure 3 and Figure 4In one embodiment, the display panel 1 further includes an anti-reflection film 50, which is disposed on the side of the circular polarizer 40 away from the second substrate 20 and covers the circular polarizer 40. The anti-reflection film 50 is used to reduce light reflection between the surface of the display panel 1 and the external environment, improve light transmission efficiency, and thereby improve display brightness and contrast.

[0052] The antireflective film 50 can be formed by a multilayer interference film or a porous structure film. By constructing a gradient refractive index structure between the air and the surface of the display panel 1, the phase and reflection path of the incident light are changed, thereby effectively suppressing the reflection of external ambient light on the surface of the display panel 1 and reducing glare.

[0053] Furthermore, the antireflective film 50 may include a plurality of first sub-layers 51 and a plurality of second sub-layers 52 stacked together, wherein the first sub-layers 51 and the second sub-layers 52 are alternately arranged along the thickness direction of the display panel 1; wherein the refractive index of the first sub-layers 51 is different from that of the second sub-layers 52, and the periodic alternation of refractive indexes achieves the interference cancellation effect on light of different wavelengths, thereby further reducing the interface reflectivity.

[0054] The material of the first sublayer 51 may include silicon dioxide (SiO2), and the material of the second sublayer 52 may include niobium pentoxide (Nb2O5). The refractive index of the first sublayer 51 is less than that of the second sublayer 52.

[0055] Specifically, the antireflective film 50 includes a first sub-layer 51, a second sub-layer 52, and a first sub-layer 51 stacked together. Since the antireflective film 50 is arranged in a structure of alternating stacking of low refractive index layer (first sub-layer 51) and high refractive index layer (second sub-layer 52), it can generate multiple optical path differences at each interface. The reflected light corresponding to different optical path differences interferes with each other, forming a destructive interference to the reflected light from the outside, thereby reducing the reflectivity of the interface.

[0056] It is understood that, compared with the display panel 1 in related technologies that does not have an anti-reflection film 50 or relies solely on polarizer reflection suppression, this embodiment, by setting the anti-reflection film 50 on the circular polarizer 40, can further reduce external light reflection, improve the visual clarity and optical uniformity of the display panel 1, and improve the user viewing experience in virtual reality display scenarios.

[0057] Please combine Figure 1 and Figure 5In one embodiment, the first substrate 10 includes a data line 1417 and a light-shielding portion 113. The data line 1417 may be disposed in the same layer as the first electrode 1415. The light-shielding portion 113 is disposed on the side of the second insulating layer 110 away from the first substrate 11. The orthographic projection of the light-shielding portion 113 on the first substrate 11 overlaps with the orthographic projection of the data line 1417 on the first substrate 11, thereby shielding the reflected light on the data line 1417.

[0058] In one embodiment, the first substrate 10 includes a data line 1417 and a light-shielding portion 113. The data line 1417 may be disposed in the same layer as the first electrode 1415, and the light-shielding portion 113 is disposed on the side of the second insulating layer 110 away from the first substrate 11. The orthographic projection of the light-shielding portion 113 on the first substrate 11 overlaps with the orthographic projection of the data line 1417 on the first substrate 11, thereby shielding the reflected light that may be generated on the data line 1417.

[0059] The data line 1417 is typically made of highly reflective metallic materials such as aluminum, aluminum alloy, copper, chromium, or molybdenum. Under external light or the light source inside the monitor, it easily generates strong reflected light. If this reflected light passes through the pixel area and enters the viewer's field of vision, it can cause problems such as bright lines, localized whitening, color shift, and decreased contrast in the displayed image. Furthermore, some light may leak between the data line 1417 and adjacent pixel areas, causing crosstalk and further affecting display quality.

[0060] It is understood that in this embodiment, by making the orthographic projection of the light-shielding part 113 on the first substrate 11 overlap with the orthographic projection of the data line 1417 on the first substrate 11, the light-shielding part 113 covers the data line 1417, thereby achieving the optical shielding function of the data line 1417. Furthermore, since the light-shielding part 113 overlaps with the data line 1417, the light-shielding part 113 can be designed as a narrow line structure with the same linewidth as the data line 1417, without having to occupy the transparent opening area between pixels. Therefore, it avoids the problem of the light-shielding part 113 occupying an additional non-light-emitting area in traditional light-shielding designs, thereby increasing the aperture ratio of the display panel 1 and further improving the display brightness and visual display effect.

[0061] Please continue to combine Figure 1 and Figure 5In one embodiment, the second substrate 20 includes a second substrate 21, a black matrix 22 disposed on the side of the second substrate 21 near the first substrate 11, and a common electrode layer 111 located on the side of the black matrix 22 near the first substrate 11; wherein, the black matrix 22 includes a first opening 221 corresponding to each of the color resist blocks 1611, the first opening 221 being used to define the light-emitting area of ​​the display panel 1, so that light from the corresponding pixel only passes through within a predetermined window, thereby achieving precise optical imaging.

[0062] Furthermore, the orthographic projection of the black matrix 22 on the first substrate 11 overlaps with the orthographic projection of the gate 1413 on the first substrate 11, and the black matrix 22 and the gate 1413 are aligned and arranged so that the black matrix 22 does not occupy the light-transmitting opening between pixels while ensuring the light-blocking function.

[0063] It is understood that the correspondence between the black matrix 22 and the color resist block 1611 can effectively limit the leakage of light along the length or width of the display panel 1, avoid light crosstalk between adjacent pixels, and improve the contrast and color purity of the display panel 1.

[0064] Meanwhile, since the orthographic projection of the black matrix 22 on the first substrate 11 overlaps with the orthographic projection of the gate 1413, the black matrix 22 can be designed as a narrow line structure with the same line width as the gate 1413, avoiding the problem of the black matrix 22 occupying a large number of pixel openings in the traditional design, thereby further improving the aperture ratio of the display panel 1 and improving the display brightness and visual display effect.
