Array substrate and display panel

Abstract

The array substrate and display panel provided in this application embodiment include an active layer, a first hydrogen absorption layer, and source / drain layers. The first hydrogen absorption layer is disposed on and connected to the active layer. This first hydrogen absorption layer has the characteristic of adsorbing hydrogen gas, effectively absorbing hydrogen elements from the active layer. By disposing of and connecting the first hydrogen absorption layer on the active layer, hydrogen elements within the active layer channel can be adsorbed, thereby reducing the hydrogen content within the active layer channel. Since the hydrogen content within the active layer channel is reduced, it does not affect the oxygen content within the active layer channel, thus preventing a decrease in carrier concentration. This helps improve the stability and reliability of the array substrate, and consequently, enhances the display performance of the liquid crystal display device.

Description

Technical Field

[0001] This application relates to the field of display technology, specifically to an array substrate and a display panel. Background Technology

[0002] Currently, Liquid Crystal Displays (LCDs), due to their low-voltage scanning drive, possess characteristics such as low power consumption, long lifespan, low cost, high brightness, low failure rate, wide viewing angle, and long viewing distance, have long been synonymous with displays and have broad application prospects. LCD devices generally use thin-film transistors (TFTs) to control their light emission. TFTs are a type of field-effect transistor; due to their high electron mobility, small subthreshold swing, and low off-state current, they are key components of LCDs and play a vital role in the display's performance.

[0003] Thin-film transistors (TFTs) typically consist of an active layer, a source, a gate, and a drain. In TFTs, the back channel etching damage and the hydrogen content of the active layer are key factors determining the quality of the device. During TFT operation, the channel region of the active layer needs to maintain a semiconductor state. The hydrogen content within the channel affects the oxygen content, leading to a decrease in carrier concentration, which in turn affects the stability of the TFT and consequently the display performance of liquid crystal displays (LCDs).

[0004] Therefore, how to develop an array substrate that can improve the stability of thin-film transistors is a challenge that existing panel manufacturers need to overcome. Summary of the Invention

[0018] This application embodiment also provides a display panel, including a color filter substrate, a liquid crystal layer, and an array substrate as described above, wherein the liquid crystal layer is disposed between the array substrates of the color filter substrate.

[0019] The array substrate and display panel provided in this application embodiment include an active layer, a first hydrogen absorption layer, and source / drain layers. The first hydrogen absorption layer is disposed on and connected to the active layer. This first hydrogen absorption layer has the characteristic of adsorbing hydrogen gas, effectively absorbing hydrogen elements from the active layer.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 1 This is a schematic diagram of a first embodiment of the array substrate provided in this application. Figure 1 As shown, the array substrate 10 provided in this embodiment includes an active layer 101, a first hydrogen absorption layer 102, and a source / drain layer 103.

[0034] The first hydrogen absorption layer 102 is disposed on the active layer 101 and is connected to the active layer 101. The source / drain layer 103 is disposed on the side of the first hydrogen absorption layer 102 away from the active layer 101.

[0035] The source-drain layer 103 includes a source and a drain, both of which are connected to the first hydrogen absorption layer 102.

[0036] It should be noted that, in this embodiment, the first hydrogen absorption layer 102 has a certain degree of conductivity. Therefore, even if the source / drain layer 103 is connected to the active layer 101 via the first hydrogen absorption layer 102, rather than being directly connected to the active layer 101, the source / drain layer 103 and the active layer 101 can still transmit signals to each other.

[0037] It should be noted that, in this embodiment, a first hydrogen-absorbing layer 102 is provided on the active layer 101. Specifically, a first hydrogen-absorbing layer 102 is provided in direct contact with the active layer 101. Firstly, the first hydrogen-absorbing layer 102 provided in this embodiment has the characteristic of adsorbing hydrogen gas, and can effectively absorb hydrogen elements in the active layer 101. Therefore, the first hydrogen-absorbing layer 102 can adsorb hydrogen elements in the channel of the active layer 101, thereby reducing the hydrogen content in the channel of the active layer 101. Since the hydrogen content in the channel of the active layer 101 is reduced, the hydrogen content in the channel of the active layer 101 will not affect the oxygen content in the channel of the active layer 101, thus preventing a decrease in the carrier concentration in the channel of the active layer 101. This helps to improve the stability and reliability of the array substrate 10, and further helps to improve the display effect of the liquid crystal display device. Secondly, the first hydrogen absorption layer 102 provided in this application embodiment also has a certain protective function, which can protect the channel of the active layer 101, improve the stability of the array substrate 10, and thus help improve the display effect of the liquid crystal display device.

[0038] The material of the first hydrogen-absorbing layer 102 includes one or a combination of graphene and carbon nanotubes.

[0039] The thickness of the first hydrogen-absorbing layer 102 is between 500 angstroms and 2000 angstroms. Specifically, the thickness of the first hydrogen-absorbing layer 102 is 500 angstroms, 600 angstroms, 700 angstroms, 850 angstroms, 900 angstroms, 1100 angstroms, 1300 angstroms, 1500 angstroms, 1750 angstroms, or 2000 angstroms. The specific thickness of the first hydrogen-absorbing layer 102 is determined by the specific requirements of the array substrate 10.

[0040] The active layer 101 can be made of low-temperature polycrystalline silicon, such as N-type doped low-temperature polycrystalline silicon, or metal oxide semiconductor materials, such as indium gallium zinc oxide (IGZO), indium gallium zinc tin oxide (IGZTO), indium zinc oxide (IZO), gallium indium oxide (IGO), indium gallium tin oxide (IGTO), indium zinc tin oxide (IZTO), indium tin oxide (ITO), etc.

[0041] It should be noted that the contact area between the first hydrogen-absorbing layer 102 and the active layer 101 is directly proportional to the effectiveness of the first hydrogen-absorbing layer 102 in adsorbing hydrogen in the channel of the active layer 101. The larger the contact area between the first hydrogen-absorbing layer 102 and the active layer 101, the better the effect of the first hydrogen-absorbing layer 102 in adsorbing hydrogen in the channel of the active layer 101.

[0042] Therefore, to ensure the adsorption capacity of the first hydrogen-absorbing layer 102, its length needs to be greater than or equal to half the length of the active layer 101. This allows it to absorb as much hydrogen as possible from the channel of the active layer 101, thereby reducing the hydrogen content within the channel. As the hydrogen content in the channel decreases, the oxygen content remains unaffected, preventing a decrease in carrier concentration. This contributes to improving the stability and reliability of the array substrate 10, ultimately enhancing the display performance of the liquid crystal display device.

[0043] Please see Figure 2 , Figure 2 This is a schematic diagram of a second embodiment of the array substrate provided in this application. Figure 2 As shown, Figure 2 The provided array substrate 10 and Figure 1 The difference in the provided array substrate 10 is that: multiple protrusions 101a are provided on the side where the active layer 101 is connected to the first hydrogen absorption layer 102, and the first hydrogen absorption layer 102 covers the protrusions 101a.

[0044] It should be noted that by providing multiple protrusions 101a on the side where the active layer 101 connects to the first hydrogen-absorbing layer 102, the contact area between the active layer 101 and the first hydrogen-absorbing layer 102 can be increased. This enhances the adsorption effect of the first hydrogen-absorbing layer 102 on hydrogen in the channel of the active layer 101, thereby reducing the hydrogen content in the channel of the active layer 101. As the hydrogen content in the channel of the active layer 101 decreases, the oxygen content remains unaffected, preventing a decrease in carrier concentration. This contributes to improving the stability and reliability of the array substrate 10, and ultimately enhances the display performance of the liquid crystal display device.

[0045] In this embodiment, the cross-sectional shape of the protrusion 101a is rectangular. Of course, the cross-sectional shape of the protrusion 101a can also be other shapes, and no specific limitation is made here.

[0046] Please see Figure 3 , Figure 3 This is a schematic diagram of a third embodiment of the array substrate provided in this application. Figure 3 As shown, Figure 3 The provided array substrate 10 and Figure 2 The difference in the provided array substrate 10 is that the side of the protrusion 101a away from the active layer 101 is arc-shaped.

[0047] It should be noted that by defining the side of the protrusion 101a away from the active layer 101 as arc-shaped, the contact area between the active layer 101 and the first hydrogen absorption layer 102 can be further increased. This further enhances the effect of the first hydrogen absorption layer 102 in adsorbing hydrogen in the channel of the active layer 101, thereby reducing the hydrogen content in the channel of the active layer 101. As the hydrogen content in the channel of the active layer 101 decreases, the oxygen content in the channel of the active layer 101 remains unaffected, thus preventing a decrease in carrier concentration in the channel of the active layer 101. This helps improve the stability and reliability of the array substrate 10, and consequently, improves the display effect of the liquid crystal display device.

[0048] Please see Figure 4 , Figure 4 This is a schematic diagram of a fourth embodiment of the array substrate provided in this application. Figure 4 As shown, Figure 4 The provided array substrate 10 and Figure 1 The difference in the provided array substrate 10 is that a first through-hole 102a is provided on the first hydrogen absorption layer 101. The first through-hole 102a penetrates the first hydrogen absorption layer 101, and the source-drain layer 103 is connected to the active layer 101 through the first through-hole 102a.

[0049] In this embodiment, the source / drain layer 103 is directly connected to the active layer 101 via a first via 102a. It should be noted that although the first hydrogen-absorbing layer 102 has some conductivity, its conductivity is not very good. Connecting the source / drain layer 103 and the active layer 101 via the first hydrogen-absorbing layer 102 would affect the signal flow between them. This embodiment improves the smoothness of signal flow between the source / drain layer 103 and the active layer 101 by providing the first via 102a, thereby enhancing the stability and reliability of the array substrate 10 and ultimately improving the display effect of the liquid crystal display device.

[0050] Specifically, the opening size of the first through-hole 102a is set as small as possible. It should be noted that external moisture can flow into the array substrate 10 through the first through-hole 102a, causing deterioration of the devices inside the array substrate 10. Therefore, setting the opening size of the first through-hole 102a as small as possible can prevent external moisture from flowing into the array substrate 10 through the first through-hole 102a, thereby helping to improve the stability and reliability of the array substrate 10, and thus helping to improve the display effect of the liquid crystal display device.

[0051] Please see Figure 5 , Figure 5 This is a schematic diagram of a fifth embodiment of the array substrate provided in this application. Figure 5 As shown, Figure 5 The provided array substrate 10 and Figure 4 The difference in the provided array substrate 10 is that the array substrate 10 further includes a second hydrogen absorption layer 104. The second hydrogen absorption layer 104 is disposed on the side of the source-drain layer 103 away from the active layer 101 and covers the outer surface of the source-drain layer 103.

[0052] It should be noted that when the source / drain layer 103 is directly connected to the active layer 101, hydrogen elements in the source / drain layer 103 may also flow to the active layer 101 through the source / drain layer 103, thereby increasing the hydrogen content inside the active layer 101. This, in turn, affects the oxygen content in the channel of the active layer 101, leading to an increase in the carrier concentration in the channel of the active layer 101. This reduces the stability and reliability of the thin-film transistor, which is detrimental to the display of the liquid crystal display device.

[0053] In this embodiment, the second hydrogen absorption layer 104 can absorb hydrogen elements inside the source / drain layer 103, preventing hydrogen elements in the source / drain layer 103 from flowing to the active layer 101. This reduces the hydrogen content inside the active layer 101, preventing the hydrogen content inside the active layer 101 from affecting the oxygen content in the channel of the active layer 101. Consequently, it reduces the carrier concentration in the channel of the active layer 101, which helps improve the stability and reliability of the array substrate 10 and improves the display effect of the liquid crystal display device.

[0054] The surface of the second hydrogen absorption layer 104 near the source / drain layer 103 can also be configured as follows: Figure 2 The active layer 101 shown has protrusions on its surface near the first hydrogen absorption layer 102, thereby increasing the contact area between the second hydrogen absorption layer 104 and the source / drain layer 103 and improving the ability of the second hydrogen absorption layer 104 to adsorb hydrogen. Specifically, the cross-section of the protrusions on the surface of the second hydrogen absorption layer 104 near the source / drain layer 103 can be rectangular, arc-shaped, or other shapes.

[0055] Please see Figure 6 , Figure 6 This is a schematic diagram of a sixth embodiment of the array substrate provided in this application. Figure 6 As shown, Figure 6 The provided array substrate 10 and Figure 1The provided array substrate differs in that the array substrate 10 further includes a first barrier layer 105, a first gate layer 106, and a first gate insulating layer 107. The first barrier layer 105 is disposed on the side of the active layer 101 near the first hydrogen absorption layer 102. The first gate layer 106 is disposed on the side of the first barrier layer 105 away from the active layer 101, and the first gate insulating layer 107 is disposed on the side of the first gate layer 106 away from the active layer 101 and covers the first gate layer 106.

[0056] It should be noted that the thin-film transistors in the array substrate 10 of this application embodiment are top-gate structures. In this application embodiment, a first barrier layer 105 is provided between the active layer 101 and the first gate layer 106. This not only better protects the active layer 101 and prevents it from being affected by other film layers, but also prevents the first gate layer 106 from being electrically connected to the channel of the active layer 101. This helps to improve the stability and reliability of the array substrate 10 and improve the display effect of the liquid crystal display device.

[0057] The thickness of the first barrier layer 105 is between 1000 angstroms and 2000 angstroms. Specifically, the thickness of the first barrier layer 105 is 1000 angstroms, 1050 angstroms, 1100 angstroms, 1200 angstroms, 1300 angstroms, 1450 angstroms, 1600 angstroms, 1800 angstroms, or 2000 angstroms. The specific thickness of the first barrier layer 105 is determined by the specific requirements of the array substrate 10.

[0058] The material of the first barrier layer 105 includes one or a combination of silicon oxide and silicon nitride.

[0059] Please see Figure 7 , Figure 7 This is a schematic diagram of a seventh embodiment of the array substrate provided in this application. (See attached diagram.) Figure 7 As shown, Figure 7 The provided array substrate 10 and Figure 6 The difference in the provided array substrate is that the first hydrogen absorption layer 102 includes a first hydrogen absorption sublayer and a second hydrogen absorption sublayer, and the first hydrogen absorption sublayer, the second hydrogen absorption sublayer, and the first barrier layer 105 are disposed in the same layer. The first hydrogen absorption sublayer and the second hydrogen absorption sublayer are respectively disposed on both sides of the first barrier layer 105.

[0060] It should be noted that since the channel region of the active layer 101 is located on both sides of the active layer 101, the first hydrogen absorption sublayer and the second hydrogen absorption sublayer are provided on both sides of the active layer 101 to absorb hydrogen elements in the channel of the active layer 101. This also reduces the thickness of the thin film transistors in the array substrate 10, making it easier to install other components.

[0061] Please see Figure 8 , Figure 8 This is a schematic diagram of a seventh embodiment of the array substrate provided in this application. (See attached diagram.) Figure 8 As shown, Figure 8 The provided array substrate 10 and Figure 7 The difference in the provided array substrate is that the array substrate 10 also includes a water-absorbing layer 108.

[0062] The first gate insulating layer 107 has a second through-hole 108a that penetrates the first gate insulating layer 107. A water-absorbing layer 108 is disposed on the first gate insulating layer 107 and connected to the first hydrogen-absorbing layer 102 via the second through-hole 108a. The water-absorbing layer 108 has a third through-hole 106a located within the second through-hole 108a, and the source / drain layer 103 is connected to the first hydrogen-absorbing layer 102 via the third through-hole 106a.

[0063] It should be noted that external moisture can flow into the array substrate 10 through the second through-hole 108a, causing deterioration of the devices inside the array substrate 10. Therefore, by providing a water-absorbing layer 108, moisture flowing into the array substrate 10 through the second through-hole 108a can be absorbed, preventing external moisture from flowing into the array substrate 10 through the second through-hole 108a. This helps improve the stability and reliability of the array substrate 10, and thus helps improve the display effect of the liquid crystal display device.

[0064] Please see Figure 9 , Figure 9 This is a schematic diagram of a seventh embodiment of the array substrate provided in this application. (See attached diagram.) Figure 9 As shown, Figure 9 The provided array substrate 10 and Figure 1 The provided array substrate differs in that the array substrate 10 further includes a second barrier layer 109, a second gate layer 110, and a second gate insulating layer 111. The second barrier layer 109 is disposed on the side of the active layer 101 away from the first hydrogen absorption layer 102. The second gate layer 110 is disposed on the side of the second barrier layer 109 away from the active layer 101. The second gate insulating layer 111 is disposed on the side of the second gate layer 110 away from the active layer 101 and covers the second gate layer 110.

[0065] It should be noted that the thin-film transistors in the array substrate 10 of this application embodiment are bottom-gate structures. In this application embodiment, a second barrier layer 109 is provided between the active layer 101 and the second gate layer 110. This not only better protects the active layer 101 and prevents it from being affected by other film layers, but also prevents the second gate layer 110 from being electrically connected to the channel of the active layer 101. This helps to improve the stability and reliability of the array substrate 10 and improve the display effect of the liquid crystal display device.

[0066] Please see Figure 10 , Figure 10 This is a schematic diagram of a seventh embodiment of the array substrate provided in this application. (See attached diagram.) Figure 10 As shown, Figure 10 The provided array substrate 10 and Figure 8 The difference in the provided array substrate is that the array substrate 10 also includes a substrate 112, which is disposed on the side of the active layer 101 away from the first gate layer 106.

[0067] It should be noted that the substrate 112 serves as a support, facilitating the formation of other films on the substrate 112. The material of the substrate 112 can be glass or the like.

[0068] The array substrate provided in this embodiment includes an active layer, a first hydrogen absorption layer, and source / drain layers. The first hydrogen absorption layer is disposed on and connected to the active layer. This first hydrogen absorption layer has the characteristic of adsorbing hydrogen gas, effectively absorbing hydrogen elements from the active layer. By disposing of and connecting the first hydrogen absorption layer on the active layer, hydrogen elements within the active layer channel can be adsorbed, thereby reducing the hydrogen content within the active layer channel. Since the hydrogen content within the active layer channel is reduced, it does not affect the oxygen content within the active layer channel, thus preventing a decrease in carrier concentration. This helps improve the stability and reliability of the array substrate, and consequently, enhances the display performance of the liquid crystal display device.

[0069] This application also provides a display panel. Please refer to [link / reference]. Figure 11 , Figure 11 This is a schematic diagram of the structure of a display panel provided in an embodiment of this application. Figure 11 As shown, the display panel 100 provided in this embodiment includes an array substrate 10, a color filter substrate 20, and a liquid crystal layer 30. The liquid crystal layer 30 is disposed between the array substrate 10 and the color filter substrate 20. The array substrate 10 has been described in detail in the above embodiments; therefore, it will not be described in further detail in this embodiment.

[0070] In this embodiment, the type of display panel 100 is not limited. It can be a vertical electric field type liquid crystal display panel, such as a twisted nematic (TN) type liquid crystal display panel or a multi-domain vertical alignment (MVA) type liquid crystal display panel. It can also be a horizontal electric field type liquid crystal display panel, such as a fringe field switching (FFS) type liquid crystal display panel or an in-plane switching (IPS) type liquid crystal display panel.

[0071] The display panel provided in this embodiment includes an active layer, a first hydrogen absorption layer, and source / drain layers. The first hydrogen absorption layer is disposed on and connected to the active layer. This first hydrogen absorption layer has the characteristic of adsorbing hydrogen gas, effectively absorbing hydrogen elements from the active layer. By disposing of and connecting the first hydrogen absorption layer on the active layer, hydrogen elements within the active layer channel can be adsorbed, thereby reducing the hydrogen content within the active layer channel. Since the hydrogen content within the active layer channel is reduced, it does not affect the oxygen content within the active layer channel, thus preventing a decrease in carrier concentration. This helps improve the stability and reliability of the array substrate, and consequently, enhances the display performance of the liquid crystal display device.
