DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined. In the description of this application, "vertical" means completely vertical at 90° or almost completely vertical, for example, an angle within the range of 80° to 100° is considered vertical. Similarly, "parallel" means completely parallel or almost completely parallel, for example, an angle within 10° of completely parallel is considered parallel.

[0034] It should also be noted that the arrow marked X in the drawings of the present application indicates the light emitting direction X. In the embodiment of the present application, the light emitting direction X is the direction from the driving circuit layer toward the light shading layer. The light emitting direction X is introduced to facilitate the description of the structural position relationship of the film layers of the display panel, thereby facilitating the understanding of its structure.

[0035] like Figure 1-Figure 3 As shown, an embodiment of the present application provides a display panel, comprising a first substrate 1, a filter layer 2, a liquid crystal layer 3, a driving circuit layer 4, a light shielding layer 5 and a second substrate 6 stacked along a light emitting direction X; the filter layer 2 is arranged on the light emitting side of the first substrate 1; the liquid crystal layer 3 is arranged on the side of the filter layer 2 away from the first substrate 1; the driving circuit layer 4 is arranged on the side of the liquid crystal layer 3 away from the filter layer 2; the light shielding layer 5 is arranged on the side of the driving circuit layer 4 away from the liquid crystal layer 3; the second substrate 6 is arranged on the side of the light shielding layer 5 away from the driving circuit layer 4; wherein the driving circuit layer 4 is provided with a channel 41, and the orthographic projection of the light shielding layer 5 on the driving circuit layer 4 covers the channel 41, and the light shielding layer 5 is used to shield and absorb light.

[0036] In the embodiment of the present application, the filter layer 2 is arranged on the light-exiting side of the backlight layer 8, the liquid crystal layer 3 is arranged on the light-exiting side of the filter layer 2, the drive circuit layer 4 is arranged on the light-exiting side of the liquid crystal layer 3, and the light shielding layer 5 is arranged on the light-exiting side of the drive circuit layer 4. In this way, the display panel of the embodiment of the present application realizes the inverted design of the array substrate and the color filter substrate, which is convenient for realizing the subsequent thinness and lightness of the whole machine.

[0037] It should be noted that the driving circuit layer 4 of the present application includes a TFT thin film transistor, and the thin film transistor includes a channel 41. The channel 41 is made of low-temperature polycrystalline silicon (LTPS). After the A / C is inverted, the shading layer 5 is located on the light-emitting side of the display panel. At this time, the original metal shading layer 5 can block part of the ambient light from directly entering the channel 41, but because the metal shading layer 5 will reflect light, on the one hand, the light emitted by the backlight will be reflected by the metal shading layer 5 into the channel 41, resulting in abnormal leakage current, and on the other hand, the ambient light will be reflected to the light-emitting side of the display panel, thus reducing the display quality. Therefore, when the driving circuit layer 4 of the TFT thin film transistor made of low-temperature polycrystalline silicon is implemented in an inverted design, it is necessary not only to perform shading treatment on the channel 41, but also to reduce the reflection of the shading layer 5. The shading layer 5 of the embodiment of the present application is used to block and absorb light, thereby reducing the reflection of light. This not only prevents the light emitted by the backlight from being reflected into the channel 41 to cause abnormal leakage current, but also reduces the reflection of ambient light and improves the display quality.

[0038] It should be noted that the first substrate 1 and the second substrate 6 in the embodiment of the present application can both be transparent substrates such as glass to ensure the transmission of light.

[0039] In addition, the present application further provides a planarization layer 9 between the liquid crystal layer 3 and the driving circuit layer 4. The planarization layer 9 is a transparent film layer, which facilitates light propagation and is used to increase the distance between the liquid crystal layer and the metal layer to achieve a better electric field effect.

[0040] Please continue to refer to Figure 1-Figure 3 In some embodiments, the light-shielding layer 5 includes a first reflection-reducing layer 51, a photoresist layer 52 and a second reflection-reducing layer 53; the first reflection-reducing layer 51 is arranged on the side of the driving circuit layer 4 away from the liquid crystal layer 3; the photoresist layer 52 is arranged on the side of the first reflection-reducing layer 51 away from the driving circuit layer 4; the second reflection-reducing layer 53 is arranged on the side of the photoresist layer 52 away from the first reflection-reducing layer 51.

[0041] In this embodiment, the first reflection reduction layer 51 is arranged on the side of the driving circuit away from the liquid crystal layer 3. At this time, the first reflection reduction layer 51 faces the channel 41. The light emitted by the backlight layer 8 irradiates the first reflection reduction layer 51. The first reflection reduction layer 51 reduces the reflection of the backlight, thereby effectively preventing the backlight from being reflected into the channel 41 after irradiating the light shielding layer 5, causing leakage current abnormality. The second reflection reduction layer 53 is arranged on the side of the photoresist layer 52 away from the first reflection reduction layer 51. At this time, the second reflection reduction layer 53 faces the second substrate 6, and the second substrate 6 is located on the light output side of the display panel. At this time, the ambient light passes through the second substrate 6 and irradiates the second reflection reduction layer 53. The second reflection reduction layer 53 also has the ability to reduce light reflection. At this time, the second reflection reduction layer 53 can effectively reduce the reflection of the incident ambient light, thereby reducing the interference of the ambient reflected light, thereby improving the display quality of the display panel. At the same time, the optical group layer is used to block the transmission of light, which has a good light shielding effect.

[0042] Please continue to refer to Figure 1-Figure 3 In some embodiments, the orthographic projections of the first reflection reducing layer 51 and the second reflection reducing layer 53 on the photoresist layer 52 cover the photoresist layer 52 .

[0043] In this embodiment, the photoresist layer 52 may be a metal film layer, in which case the metal is a non-transparent layer, thereby effectively preventing the incident ambient light from penetrating, thereby preventing the incident ambient light from irradiating into the channel 41. Since the metal film layer has a reflective capability, in order to prevent the photoresist layer 52 made of the metal film layer from reflecting light toward the channel 41 and the light-emitting side of the display panel, the first and second reflection-reducing layers 51 and 53 are disposed on the photoresist layer 52 so that their orthographic projections cover the photoresist layer 52, which is equivalent to the first and second reflection-reducing layers 51 and 53 having an area at least equal to that of the photoresist layer 52 and completely covering both sides of the photoresist layer 52 along the light-emitting direction X. In this way, the reflection of the backlight and the incident ambient light by the photoresist layer 52 can be completely avoided, thereby improving the reflection-reducing effect of the light-shielding layer 5.

[0044] like Figure 2 As shown, in some embodiments, the first reflection reducing layer 51 and the second reflection reducing layer 53 are semi-transparent and semi-reflective metal oxide layers.

[0045] Furthermore, the photoresist layer 52 may be a low-reflection metal film layer. In this case, the light-blocking layer not only has a good light-shielding effect, but also can reduce the reflection of backlight and ambient light, thereby improving the anti-reflection effect of the light-shielding layer 5 .

[0046] In the embodiment of the present application, the shading layer 5 adopts a laminated structure of metal and metal oxide. The semi-transparent and semi-reflective metal oxide layer has the ability to reduce the reflection of light. By arranging the semi-transparent and semi-reflective metal oxide layer on both sides of the photoresist layer 52 along the light emitting direction X of the display panel, the reflection of light can be effectively reduced, and the impact on the display effect of the display panel can be reduced.

[0047] It should be noted that, in the embodiments of the present application, by adjusting the thickness and refractive index of the metal oxide film, a better effect of reducing reflection can be achieved.

[0048] In the embodiment of the present application, the thickness of the photoresist layer 52 can be 40-150nm, and the thickness of the first and second reflection reducing layers 51 and 53 can be 40-90nm. The thickness of the photoresist layer 52, the first and second reflection reducing layers 51 and 53 is set within the above range. On the one hand, it is ensured that they have a certain thickness to achieve their effect of reducing reflection, and on the other hand, it is also avoided that the film layer is too thick, resulting in a reduction in its reflection reducing effect. Since the reflection reducing effect of the reflection reducing layer will first increase and then decrease as its thickness increases, therefore, setting the thickness of the reflection reducing layer within the above range can ensure that its reflection reducing effect is within the expected range.

[0049] like Figure 3 As shown, in some embodiments, the first reflection reducing layer 51 and the second reflection reducing layer 53 both include a stacked first metal layer 54 and a first inorganic film layer 55, the first inorganic film layer 55 is disposed on one side of the photoresist layer 52, and the first metal layer 54 is disposed on the side of the first inorganic film layer 55 away from the photoresist layer 52.

[0050] In the embodiment of the present application, the light shielding layer 5 adopts a laminated structure of metal and inorganic film layers, wherein the first metal layer 54 is a metal film with low reflectivity, and is thin as a whole, and can achieve partial transmission and partial reflection of light, and the reflectivity is relatively low. At this time, the light enters the first inorganic film layer 55 after passing through the metal film, and the refractive index of the first inorganic film layer 55 is greater than the refractive index of the substrate. Therefore, after passing through the substrate, the light enters the first metal layer 54 and undergoes a first refraction, and then enters the first inorganic film layer 55 and undergoes a second refraction, and then enters the photoresist layer 52, and enters the first inorganic film layer 55 and the first metal layer 54 again through the reflection of the photoresist layer 52. In the process of light propagation, the coherent decomposition of the incident light and the reflected light is achieved, thereby improving the anti-reflection effect of the light shielding layer 5.

[0051] In some embodiments, the first metal layer 54 is a semi-transmissive and semi-reflective low-reflection metal film layer, and the refractive index of the first inorganic film layer 55 is greater than the refractive index of the second substrate 6 .

[0052] In this embodiment, the first metal layer 54 has a semi-transparent and semi-reflective property and has a relatively low reflectivity, which can reduce the reflection of the incident light and realize the transmission of part of the incident light, ensuring that part of the light passes through the first metal layer 54 and passes through the first inorganic film layer 55 to be reflected by the photoresist layer 52. It should be noted that the refractive index of the first inorganic film layer 55 is relatively high. At this time, the incident light and the reflected light are coherently destructed in the first inorganic film layer 55, reducing the emission of the reflected light, and the remaining part of the light passes through the first inorganic film layer 55 and reaches the first metal layer 54, and will be partially reflected and enter the first inorganic film layer 55. In this way, the light is reduced in a cycle, thereby reducing the reflection effect of the light shielding layer 5 on the light as a whole.

[0053] Furthermore, in this embodiment, the thickness of the photoresist layer 52 can be 40-150nm, the thickness of the first metal layer 54 can be 5-15nm, and the thickness of the first inorganic film layer 55 can be 40-90nm. Among them, the light group layer is set within this range to ensure that it has a good light shielding effect; the first metal layer 54 is set with a thinner film structure, which can make the first metal layer 54 have a certain light transmittance and realize the semi-transparent and semi-reflective performance of the first metal layer 54; the first inorganic film layer 55 is set within this thickness range, so that the display panel has a certain transmittance, which is conducive to the coherent destructing of light. In addition, the first metal layer 54 and the photoresist layer 52 are both made of metal with low reflectivity, which can further improve the anti-reflection effect of the light shielding layer 5.

[0054] In some embodiments, a second inorganic film layer 7 is disposed on a side of the second reflection reducing layer 53 facing away from the photoresist layer 52 , and a refractive index of the second inorganic film layer 7 is greater than a refractive index of the second substrate 6 .

[0055] In the embodiment of the present application, the second inorganic film layer 7 is arranged between the second substrate 6 and the second reflection reducing layer 53. At this time, the refractive index of the second inorganic film layer 7 is greater than the refractive index of the second substrate 6, so that the light is refracted in the second inorganic film layer 7 after being incident from the second substrate 6, and then enters the second reflection reducing layer 53. Part of the light passes through the second reflection reducing layer 53 and reaches the photoresist layer 52 for reflection. Then a small amount of light passes through the second reflection reducing layer 53 and enters the second inorganic film layer 7, and the coherent decomposition of the incident light and the reflected light is carried out in the second inorganic film layer 7, thereby further reducing the reflection of the incident ambient light and improving the quality of the display panel.

[0056] like Figure 1 As shown, in some embodiments, the driving circuit layer 4 includes a thin film transistor 42 , and the orthographic projection of the light shielding layer 5 on the driving circuit layer 4 covers the thin film transistor 42 .

[0057] In the embodiment of the present application, the shading layer 5 completely covers the thin film transistor 42 and can completely block the thin film transistor 42, so that the incident ambient light incident from the light-emitting side of the display panel will not hit the thin film transistor 42, thereby avoiding the thin film transistor 42 from reflecting the incident ambient light, further avoiding the influence of reflected light on the display effect, and improving the display quality.

[0058] In some embodiments, the thin film transistor 42 includes a second metal layer 421 , which is disposed on a side of the channel 41 away from the light shielding layer 5 , and an orthographic projection of the second metal layer 421 on the channel 41 covers the channel 41 .

[0059] In the embodiment of the present application, the second metal layer 421 is disposed on the side of the channel 41 away from the light shielding layer 5. In other words, the second metal layer 421 is disposed between the channel 41 and the backlight layer 8. At this time, the second metal layer 421 can shield the channel 41 to prevent the backlight from directly entering the channel 41 and affecting the leakage current. That is, the second metal layer 421 is not only a part of the TFT thin film transistor, but also plays a role in shielding the channel 41.

[0060] Accordingly, a display device according to an embodiment of the present application includes a display panel according to any one of the above embodiments, and the backlight layer 8 is arranged on the side of the first substrate 1 away from the filter layer 2. The backlight layer 8 provides backlight for the display panel to achieve normal display of the display panel.

[0061] It can be understood that the display device of the embodiment of the present application includes all the technical features and technical effects of the display panel, which will not be repeated here.

[0062] It should be noted that the display device of the embodiment of the present application may be: a mobile phone, a television, a display screen, a car display, a learning machine and other display devices.
