Description

Technical Field

[0001] This application relates to the field of display technologies, and in particular to an array substrate, a display module, and a display device. Background Art

[0002] With the rapid development of display technologies, the usage scenario requirements for display devices are continuously enriched, and thus the design of array substrates is gradually developing towards multi-functional integration.

[0003] In current mainstream display devices, the pixel electrode, as the core structure for realizing optoelectronic conversion, has a great influence on the display performance of the display device. In related technologies, pixel electrodes are usually made of transmissive materials or reflective materials, such that the display device realizes the image display function only by one way of reflecting light or transmitting light, which is not conducive to the diverse requirements of people for display devices. Summary of the Invention

[0004] Embodiments of this application provide an array substrate, a display module, and a display device, so as to at least solve the problem of the single way of realizing the display function in the display device in related technologies.

[0005] On the one hand, embodiments of this application provide an array substrate, which includes:

[0006] A substrate;

[0007] A plurality of sub-pixels, disposed on the substrate;

[0008] Wherein, each of the sub-pixels includes a pixel electrode, and at least one of the pixel electrodes includes a reflective sub-electrode and a transmissive sub-electrode that are arranged in different layers and connected to each other, and a first orthographic projection of the reflective sub-electrode on the substrate is within a range of a second orthographic projection of the transmissive sub-electrode on the substrate.

[0009] In some embodiments, a ratio of an area of the first orthographic projection to an area of the second orthographic projection is greater than or equal to 0.3 and less than or equal to 0.6.

[0010] In some embodiments, at least three of the sub-pixels form a pixel, and a plurality of the pixels are arranged in an array. In the pixel, at least three of the sub-pixels include a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel; in a plurality of the pixels, the pixel electrode of each of the first color sub-pixels includes the reflective sub-electrode and the transmissive sub-electrode.

[0011] In some embodiments, the first color is one of red and blue.

[0012] In some embodiments, among the plurality of pixels, the pixel electrode of each second color sub-pixel includes a transmissive portion, and the second color is different from the first color.

[0013] In some embodiments, in each of the pixels, all the pixel electrodes respectively include the reflective sub-electrode and the transmissive sub-electrode.

[0014] In some embodiments, in each of the pixels, the reflective sub-electrodes are arranged side by side.

[0015] In some embodiments, the array substrate further includes a gate layer disposed on the substrate, and a gate insulating layer, an active layer, and a source-drain electrode layer sequentially disposed along a direction away from the substrate of the gate layer. The reflective sub-electrode is located in the source-drain electrode layer.

[0016] In some embodiments, the array substrate further includes a passivation layer. A first via hole and a second via hole are formed in the passivation layer. The transmissive sub-electrode is electrically connected to the source-drain electrode layer through the first via hole, and the transmissive sub-electrode is electrically connected to the reflective sub-electrode through the second via hole.

[0017] On the other hand, an embodiment of the present application further provides a display module, and the display module includes the array substrate as described in any of the above embodiments.

[0018] In yet another aspect, an embodiment of the present application further provides a display device. The display device includes a backlight module and the display module as described in the above embodiments. The backlight module is disposed on one side of the array substrate. The display module further includes: a liquid crystal layer and a color filter substrate sequentially disposed on a side of the array substrate away from the backlight module; the color filter substrate includes a substrate, a black matrix on one side of the substrate, and a common electrode layer on a side of the black matrix away from the substrate; the black matrix defines a plurality of pixel openings, and a color resist block is disposed in each pixel opening.

[0019] For the array substrate provided by the embodiments of the present application, since the reflective sub-electrodes and the transmissive sub-electrodes are located in different film layers, it is beneficial to fabricate the reflective sub-electrodes and the transmissive sub-electrodes. Moreover, since the reflective sub-electrodes and the transmissive sub-electrodes are connected, the formation of parasitic capacitance in the overlapping portion of the reflective sub-electrodes and the transmissive sub-electrodes can be avoided, thereby preventing the display device using the array substrate from being affected by the parasitic capacitance and resulting in poor picture display effects. In addition, since the first orthographic projection of the reflective sub-electrodes on the substrate is within the range of the second orthographic projection of the transmissive sub-electrodes on the substrate, a part of the transmissive sub-electrodes extends beyond the area where the reflective sub-electrodes are located and is used to transmit light, so as to ensure the display of the picture by the display device using the array substrate. Therefore, the array substrate provided by the embodiments of the present application can reflect light using the reflective sub-electrodes or transmit light using the transmissive sub-electrodes, thereby meeting the diverse display requirements of people for the array substrate and the display device using the same.

[0028] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. The described technical solutions are only used to explain and illustrate the idea of the present application, and should not be regarded as a limitation on the protection scope of the present application.

Terms such as "a plurality of" and similar words mean two or more, unless otherwise clearly defined.

[0031] The use of "suitable for" or "configured to" in the present application means open and inclusive language, which does not exclude a device suitable for or configured to perform additional tasks or steps. Additionally, the use of "based on" means open and inclusive, because a process, step, calculation or other action "based on" one or more of the stated conditions or values can in practice be based on additional conditions or values beyond those stated.

[0032] In the present application, the term "exemplary" is used to mean "serving as an example, illustration, or explanation". Any embodiment described as "exemplary" in the present application is not necessarily to be construed as more preferred or advantageous than other embodiments. The following description is given to enable any person skilled in the art to implement and use the present application.

[0033] The various embodiments of the present application are similar, and the features in different embodiments and / or different examples can be combined with each other.

[0034] Some embodiments of the present application provide an array substrate, as Figure 1 shown, the array substrate 100 includes a substrate 10 and a plurality of sub-pixels SP disposed on the substrate 10.

[0035] As Figure 2 and Figure 3 shown, each sub-pixel SP includes a pixel electrode 31 and a pixel circuit 21 connected to the pixel electrode 31. Among all the pixel electrodes 31 included in the plurality of sub-pixels SP, at least one pixel electrode 31 includes a reflective sub-electrode 311 and a transmissive sub-electrode 312 that are disposed in different layers and connected to each other, and a first orthographic projection M1 of the reflective sub-electrode 311 on the substrate 10 is within a range of a second orthographic projection M2 of the transmissive sub-electrode 312 on the substrate 10.

[0036] Among them, the transmissive sub-electrode 312 can be used to transmit light from the back surface of the array substrate 100 (i.e., the side of the substrate 10 away from the pixel P), and the reflective sub-electrode 311 is used to reflect light from the front surface of the array substrate 100 (i.e., the side of the pixel P away from the substrate 10), so as to enable the display device including the array substrate 100 to have good display functions and thus meet different usage requirements of users. As an example, when the array substrate 100 is applied to a liquid crystal display device, the liquid crystal display device further includes a backlight module. When the backlight module is turned on, the light emitted by the backlight module can be emitted through the transmissive sub-electrode 312, thereby realizing the display of an image or a picture. When the backlight module is turned off, the reflective sub-electrode 311 can reflect the ambient light on the front surface of the array substrate 100, thereby forming an image or a pattern for the user to view.

[0037] In this embodiment, since the reflective sub-electrode 311 and the transmissive sub-electrode 312 are located in different film layers, this is conducive to the fabrication of the reflective sub-electrode 311 and the transmissive sub-electrode 312. Moreover, since the reflective sub-electrode 311 and the transmissive sub-electrode 312 are connected, this can avoid the formation of parasitic capacitance in the overlapping part of the reflective sub-electrode 311 and the transmissive sub-electrode 312, and further avoid the problem that the display device applied to the array substrate 100 is affected by the parasitic capacitance and the display effect of the picture is poor. In addition, since the first orthographic projection M1 of the reflective sub-electrode 311 on the substrate 10 is within the range of the second orthographic projection M2 of the transmissive sub-electrode 312 on the substrate 10, a part of the transmissive sub-electrode 312 extends beyond the area where the reflective sub-electrode 311 is located and is used to transmit light, so as to ensure the display of the picture by the display device applied to the array substrate 100. Therefore, the array substrate 100 provided by the embodiment of the present application can use the reflective sub-electrode 311 to reflect light or use the transmissive sub-electrode 312 to transmit light, so as to meet the diverse display requirements of people for the array substrate 100 and the display device applied thereto.

[0038] As Figure 2 shown, in the area occupied by the transmissive sub-electrode 312, a part of the area is a light-transmitting area P1, and the other part of the area is a reflective area P2. In the reflective area P2, a part of the transmissive sub-electrode 312 is overlapped with the reflective sub-electrode 311. When the array substrate 100 is applied to a liquid crystal display device, the light emitted by the backlight module can be emitted through the light-transmitting area P1, and the ambient light will be reflected under the action of the reflective sub-electrode 311 in the reflective area P2, so that the area of light emission can be adjusted to meet the diverse display requirements of people.

[0039] It should be noted that the first orthographic projection M1 of the reflective sub-electrode 311 on the substrate 10 and the second orthographic projection M2 of the transmissive sub-electrode 312 on the substrate 10 are both projections of the corresponding sub-electrode along the thickness direction Z of the array substrate 100.

[0040] In some examples, the reflective sub-electrode 311 can be made of a metal reflective material, such as aluminum, aluminum alloy, silver, or silver alloy, etc. The material of the transmissive sub-electrode 312 can be a transparent conductive oxide, such as indium tin oxide or indium zinc oxide, etc.

[0041] In some embodiments, as Figure 3 shown, the edge of the first orthographic projection M1 does not overlap with the edge of the second orthographic projection M2. That is to say, the second orthographic projection M2 surrounds the first orthographic projection M1. With such a setting, the geometric center of the reflective sub-electrode 311 can be close to the geometric center of the transmissive sub-electrode 312, or further, the geometric centers of the reflective sub-electrode 311 and the transmissive sub-electrode 312 overlap. In this way, whether the light is reflected by the reflective sub-electrode 311 or transmitted by the transmissive sub-electrode 312, the light has relatively good concentration, which is beneficial to improving the picture display effect of the display device applied to the array substrate 100.

[0042] In some embodiments, the transmissive sub-electrode 312 includes a main body portion and a connecting portion, and the connecting portion is used to connect the pixel circuit 21. Among them, the third projection M21 of the main body portion on the substrate 10 surrounds the first orthographic projection M1, and the fourth projection M22 of the connecting portion on the substrate 10 is located on one side of the third projection M21 of the main body portion on the substrate 10. As an example, both the first orthographic projection M1 and the third projection M21 are regular figures. Exemplarily, at least one of the first orthographic projection M1 and the third projection M21 is a rectangle, a square, or a circle, etc.

[0043] In some examples, the first orthographic projection M1 can be located at a position away from the fourth projection M22 in the third projection M21.

[0044] In other examples, the geometric centers of the first orthographic projection M1 and the third projection M21 coincide. In this case, the geometric center of the reflective sub-electrode 311 overlaps with the geometric center of the main body portion of the transmissive sub-electrode 312. In this way, whether the light is reflected by the reflective sub-electrode 311 or transmitted by the transmissive sub-electrode 312, the light has good concentration, thereby improving the picture display effect of the display device applied to the array substrate 100.

[0045] In some embodiments, as Figure 3 shown, the ratio of the area of the first orthographic projection M1 to the area of the second orthographic projection M2 is greater than or equal to 0.3 and less than or equal to 0.6.

[0046] By setting it in this way, on the one hand, it can effectively avoid the problem that the area of the reflective sub-electrode 311 is too small, resulting in poor reflection effect of the array substrate 100 on ambient light and making it difficult for users to observe the reflected light; on the other hand, it can also effectively avoid the problem that the area of the reflective sub-electrode 311 is too large, resulting in poor transmission effect of the array substrate 100 on the light participating in the display of the picture and poor user experience in viewing the display picture.

[0047] In some embodiments, such as Figure 1 As shown, at least three sub-pixels SP form a pixel P, and a plurality of pixels P are arranged in an array. For example, a plurality of pixels P are arranged in multiple rows and multiple columns. In each pixel P, at least three sub-pixels SP include a first-color sub-pixel SP1, a second-color sub-pixel SP2, and a third-color sub-pixel SP3, where the first-color sub-pixel SP1, the second-color sub-pixel SP2, and the third-color sub-pixel SP3 correspond to light of different colors. For example, when the first-color sub-pixel SP1 is turned on, the display device applied to the array substrate can emit light of the first color; when the second-color sub-pixel SP2 is turned on, the display device can emit light of the second color; when the third-color sub-pixel SP3 is turned on, the display device can emit light of the third color. In this way, the light of the first color, the second color, and the third color can be mixed according to the display needs, so as to realize the color display of the display panel.

[0048] As an example, when the array substrate 100 is applied to a liquid crystal display device, the liquid crystal display device further includes a liquid crystal layer and a color filter substrate. The color resist blocks in the color filter substrate can allow light of corresponding colors to pass through. For example, the red color resist block allows red light to pass through, the green color resist block allows green light to pass through, and the blue color resist block allows blue light to pass through. In this case, the pixel electrode 31 of the first-color sub-pixel SP1 can be aligned with one of the red color resist block, the green color resist block, and the blue color resist block, and the pixel electrodes of the second-color sub-pixel SP2 and the third-color sub-pixel SP3 are aligned with the remaining two, so as to ensure that the liquid crystal display device can emit light of three colors: red, green, and blue. It should be noted that for any sub-pixel SP, the pixel electrode 31 therein can cooperate with the common electrode layer in the color filter substrate to control the deflection of the liquid crystal molecules in the region corresponding to the pixel electrode 31, so as to control whether light passes through this region.

[0049] In some examples, among a plurality of pixels P, the pixel electrode 31 of each first-color sub-pixel SP1 includes a reflective sub-electrode 311 and a transmissive sub-electrode 312. That is to say, among all the pixel electrodes 31, the pixel electrodes 31 participating in the control of the same-color light (i.e., the first-color light) are all structures composed of the reflective sub-electrode 311 and the transmissive sub-electrode 312.

[0050] With such a setting, all the reflective sub-electrodes 311 in the array substrate 100 are arranged in an array, so that the array substrate 100 can have a good reflection effect on ambient light.

[0051] In some embodiments, the first color may be green.

[0052] In some other embodiments, the first color is one of red and blue.

[0053] It should be noted that red light, green light, and blue light can be mixed to form white light. In the white light formed by the mixture, the brightness ratio of red light, green light, and blue light is approximately 3:6:1. And the brightness of the emitted light is related to the area of the light passing through the transmissive sub-electrode 312 (i.e., the area of the part where the transmissive sub-electrode 312 does not overlap with the reflective sub-electrode 311) and the light transmittance of the color resist block. Therefore, by setting the first color light as red light or blue light, the area of the light passing through the transmissive sub-electrode 312 can be adjusted by changing the area of the reflective sub-electrode 311, so as to achieve a good light emission effect.

[0054] In some examples, the areas of the orthographic projections of all the pixel electrodes 31 on the substrate 10 are equal. In this case, since each pixel electrode 31 of the first color sub-pixel SP1 includes a reflective sub-electrode 311 and a transmissive sub-electrode 312, this results in a reduction in the area of the light passing through the transmissive sub-electrode 312. Therefore, the light transmittance of the corresponding color resist block increases, which can reduce the addition of dyes (such as azo compounds) for filtering colors in the color resist block, thus facilitating the saving of the manufacturing cost of the color resist layer (the layer where the color resist block is located), and further saving the manufacturing cost of the display device to which the array substrate 100 is applied.

[0055] In some embodiments, as Figure 1 and Figure 5 shown, in each pixel P, all the pixel electrodes 31 respectively include a reflective sub-electrode 311 and a transmissive sub-electrode 312. That is to say, all the pixel electrodes 31 in the array substrate 100 are structures composed of a reflective sub-electrode 311 and a transmissive sub-electrode 312.

[0056] With such a setting, the total reflection area of all the reflective sub-electrodes 311 in the array substrate 100 is relatively large, so that the array substrate 100 can have an excellent reflection effect on ambient light.

[0057] In addition, when the array substrate 100 is applied to a liquid crystal display device and the backlight module is turned off, by transmitting a signal to a specific pixel electrode 31 in each pixel P, the deflection of liquid crystal molecules in the region corresponding to the pixel electrode 31 in the liquid crystal layer can be controlled, thereby controlling the passage of ambient light through this region. The propagation process of ambient light in the liquid crystal display device is as follows: The ambient light first passes through the color filter block above the pixel electrode 31, then passes through the liquid crystal molecules, and is reflected under the action of the reflective sub-electrode 311. Then, it passes through the liquid crystal molecules and the color filter block in sequence and exits, so as to finally output light of the color corresponding to the color filter block to the user. Therefore, by transmitting a signal to some pixel electrodes 31 in the array substrate 100 (these pixel electrodes 31 can participate in the control of light of the same color or different colors), a monochromatic or color personalized texture pattern can be displayed, thereby enhancing the user experience.

[0058] In some examples, please continue to refer to Figure 5 , in each pixel P, all the reflective sub-electrodes 311 are arranged side by side.

[0059] With such an arrangement, in each pixel P, the region for reflecting light where the reflective sub-electrode 311 is located is relatively concentrated and uniform, which is beneficial to improving the light reflection effect of each pixel P. In addition, the above arrangement can also make all the reflective sub-electrodes 311 in the array substrate 100 arranged in an array, which is beneficial to improving the display effect of the personalized texture pattern.

[0060] In some other embodiments, as Figure 4 and Figure 6 shown, in multiple pixels P, the pixel electrode 31 of each second color sub-pixel SP2 includes a transmissive portion 313, and the second color is different from the first color. The transmissive portion 313 and the transmissive sub-electrode 312 can be located in the same film layer, which is beneficial to saving the manufacturing process. In addition, the transmissive portion 313 and the transmissive sub-electrode 312 can be made of the same material, which will not be elaborated here.

[0061] In some examples, three pixel electrodes 31 are provided in each pixel P. For example, in multiple pixels P, the pixel electrode 31 of each third color sub-pixel SP3 can have the same structure as the pixel electrode 31 of the second color sub-pixel SP2. At this time, the liquid crystal display device to which the array substrate 100 is applied can only achieve the display of a monochromatic personalized texture pattern when reflecting ambient light. Another example is that in multiple pixels P, the pixel electrode 31 of each third color sub-pixel SP3 can have the same structure as the pixel electrode 31 of the first color sub-pixel SP1. At this time, the liquid crystal display device to which the array substrate 100 is applied can achieve the display of a multi-color personalized texture pattern when reflecting ambient light.

[0062] In some examples, the second color may be green. When the first color is blue, the third color is red; when the first color is red, the third color is blue.

[0063] In some embodiments, as Figure 2 shown, the sub-pixel SP further includes a pixel circuit 21 electrically connected to the pixel electrode 31. The pixel electrode 31 is located in the pixel electrode layer 30, and the pixel circuit 21 is located in the pixel circuit layer 20. Among them, the pixel circuit layer 20 includes a gate layer 201 disposed on the substrate 10, and a gate insulating layer 202, an active layer 203, and a source-drain electrode layer 204 sequentially disposed along the direction away from the substrate 10 of the gate layer 201. The reflective sub-electrode 311 is located in the source-drain electrode layer 204.

[0064] In this case, the reflective sub-electrode 311 can be fabricated during the fabrication process of the source-drain electrode layer 204, which is beneficial to improving the fabrication efficiency of the array substrate 100.

[0065] In some embodiments, please continue to refer to Figure 2 , the pixel circuit layer 20 further includes a passivation layer 205. The passivation layer 205 is provided with a first via hole H1 and a second via hole H2. The transmissive sub-electrode 312 is electrically connected to the source-drain electrode layer 204 through the first via hole H1, and the transmissive sub-electrode 312 is electrically connected to the reflective sub-electrode 311 through the second via hole H2. Such a setting can achieve a good and stable connection relationship of the pixel electrode 31.

[0066] In some examples, the pixel circuit 21 includes a thin film transistor. The gate of the thin film transistor is located in the gate layer 201, the channel of the thin film transistor is located in the active layer 203, and the source and drain of the thin film transistor are both located in the source-drain electrode layer 204. The drain of the thin film transistor can be connected to the transmissive sub-electrode 312 through the first via hole H1, so as to realize the connection between the pixel circuit 21 and the pixel electrode 31.

[0067] It should be noted that in the case where the transmissive sub-electrode 312 includes the above-mentioned main body portion and connection portion, the connection portion is connected to the drain of the thin film transistor.

[0068] Some embodiments of the present application provide a display module, as Figure 7 shown, the display module 200 includes the array substrate 100 of any one of the above embodiments.

[0069] Since it includes the array substrate 100, the display module 200 has the technical effects of the above-mentioned array substrate 100, which will not be elaborated here.

[0070] Some embodiments of the present application provide a display device. Please continue to refer to Figure 7, the display device 1000 includes a backlight module 300 and the above-mentioned display module 200.

[0071] Since the display module 200 includes an array substrate 100, the display device 1000 has the technical effects of the above-mentioned array substrate 100, which will not be elaborated here.

[0072] In some examples, the backlight module 300 is located on one side of the substrate 10. The display module 200 further includes a liquid crystal layer 40 and a color filter substrate 50 that are sequentially arranged on the side of the array substrate 100 away from the backlight module 300. Among them, the color filter substrate 50 includes a substrate 51, a black matrix 52 located on one side of the substrate 51, and a common electrode layer 54 located on the side of the black matrix 52 away from the substrate 51; the black matrix 52 defines a plurality of pixel openings, and a color resist block 53 is provided in each pixel opening.

[0073] For the display device 1000 provided by the embodiments of the present application, when the backlight module 300 is turned on, the light emitted by the backlight module 300 can exit through the transmissive sub-electrode 312, so as to realize the normal screen display function of the display device 1000. When the backlight module 300 is turned off, the reflective sub-electrode 311 can reflect the ambient light on the front side of the array substrate 100, so as to form a pattern for the user to view. By outputting signals to different pixel electrodes 31 having reflective sub-electrodes 311, the pattern formed by reflecting ambient light can be flexibly adjusted, so as to achieve dynamic pattern display. In addition, when the backlight module 300 is turned off, the display device 1000 can still realize pattern display, so that the power consumption of the display device 1000 is reduced to a considerable extent.

[0074] In some examples, the display device 1000 can be applied to an in-vehicle display. When the in-vehicle display forms a pattern by reflecting ambient light, by adjusting the pattern, the pattern or texture reflected by the in-vehicle display can be made to be consistent with the interior or background around the in-vehicle display, so that the in-vehicle display can be integrated with the vehicle body to improve the user experience.

[0075] In some examples, the light source in the backlight module 300 can be a micro light-emitting diode (Light-Emitting Diode, LED), such as a Micro LED or a Mini LED. This can improve the light-emitting brightness of the backlight module 300, so as to be beneficial to improving the display effect of the screen displayed by the display device 1000 through the transmissive sub-electrode 312.

[0076] In some examples, the display module 200 in the display device 1000 may further include support pillars located between the array substrate 100 and the color filter substrate 50, and the liquid crystal layer 40 is disposed to surround the support pillars, thereby ensuring a relatively stable spacing between the array substrate 100 and the color filter substrate 50 to guarantee the structural stability of the display module 200.

[0077] In some examples, the display module 200 further includes a sealant located between the array substrate 100 and the color filter substrate 50, and the sealant is disposed to surround the liquid crystal layer 40.

[0078] The embodiments of the present application have been introduced in detail above. Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
