Similar components in the accompanying drawings are represented by the same reference numerals. It should be understood by those skilled in the art that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0044] It should be noted that the terms “on…”, “formed on…” and “disposed on…” described herein may indicate that one layer is directly formed or disposed on another layer, or may indicate that one layer is indirectly formed or disposed on another layer, i.e., there are other layers between the two layers. In this article, unless otherwise specified, the term “located on the same layer” used means that two layers, parts, components, elements or parts can be formed by the same patterning process, and the two layers, parts, components, elements or parts are generally formed of the same material. In this article, unless otherwise specified, the expression “patterning process” generally includes steps such as coating, exposure, development, etching and stripping of photoresist. The expression “one-time patterning process” means a process of forming patterned layers, parts, components, etc. using a mask.

[0045] In view of the problems existing in related technologies, such as Figure 1 As shown, an embodiment of the present invention provides an array substrate, comprising a plurality of sub-pixel units arranged in an array on a substrate 10, each sub-pixel unit comprising a transmission area 30 and a reflection area 20 arranged in parallel, wherein

[0046] The reflective area 20 includes a driving circuit layer and a reflective layer 22 stacked on the substrate 10, the driving circuit layer includes a first thin film transistor 211 for driving the liquid crystal molecules in the transmission area, and a second thin film transistor 212 for driving the liquid crystal molecules in the reflective area;

[0047] The transmission area 30 includes a first electrode layer 31 and a lens layer 32 stacked on the substrate 10. The first electrode layer 31 is electrically connected to the first thin film transistor 211. The lens layer 32 includes a plurality of lenses for adjusting the brightness of light emitted from the transmission area.

[0048] In this embodiment, a lens layer for adjusting the brightness of light emitted from the transmission area is provided on the transmission area, so that the brightness of light emitted from the transmission area is consistent with that of light emitted from the reflection area. Specifically, by adjusting the number of lenses and the parameters of the lenses, the backlight entering the transmission area becomes collimated light after passing through the lens, thereby achieving the convergence effect of light emission; at the same time, the ambient light entering the transmission area is reflected on the lens surface, further improving the light utilization rate of the incident light; by collimating the backlight and reflecting the incident light, it is possible to achieve light focusing and improve the brightness of light emitted from the transmission area, thereby compensating for the problems existing in the prior art, effectively improving the display effect of the display device, and having practical application value.

[0049] At the same time, this embodiment realizes reflection of incident light by uniformly setting the driving circuit of the sub-pixel unit in the reflective area and setting a reflective layer on the driving circuit; forms a first electrode in the transmission area and sets a lens layer on the first electrode, while improving the brightness of the light output in the transmission area, uniformizing the substrate thickness of the reflective area and the transmission area, thereby further improving the display effect of the display device.

[0050] In an optional embodiment, if Figure 1 As shown, in a first direction y perpendicular to the substrate, a height of the reflective region 20 away from the surface of one side of the substrate is equal to a height of the transmissive region 30 away from the surface of one side of the substrate.

[0051] In this embodiment, by adjusting the height of the driving circuit layer and the reflective layer, as well as adjusting the height of the first electrode and the lens layer, the heights of the reflective area and the transmissive area relative to the substrate are made equal, that is, the reflective area and the transmissive area of ​​equal thickness are formed, which can improve the display effect of the display device.

[0052] It is worth noting that, considering the actual preparation situation, when the height difference between the reflective area and the transmissive area is less than or equal to 0.35 μm, it is considered that the heights of the reflective area and the transmissive area are equal. Those skilled in the art should understand and set the height difference range according to actual application requirements to achieve equal thickness of the reflective area and the transmissive area and improve the display effect as the design criteria, which will not be repeated here.

[0053] In an optional embodiment, if Figure 1 As shown, in a second direction x perpendicular to the first direction y, the orthographic projection width of the transmission area 20 on the substrate 10 is the same as the orthographic projection width of the reflection area 30 on the substrate 10 .

[0054] In this embodiment, the spatial positions of the reflective area and the transmissive area are further set, such as Figure 1 As shown, in the direction x parallel to the substrate, that is, the sub-pixel unit is in the longitudinal section perpendicular to the substrate 10, the cross-sectional width of the sub-pixel unit is divided into two equal parts, which are respectively set as a reflection area and a transmission area, that is, in terms of the orthographic projection on the substrate, in the x direction, the orthographic projection widths of the reflection area and the transmission area are the same, thereby further making the reflection area and the transmission area uniform and improving the display effect of the display device.

[0055] It is worth noting that, taking into account the actual preparation conditions, as well as the resolution requirements of different display products and the size requirements of sub-pixel units, when the width difference between the reflective area and the transmissive area is less than or equal to 10% of their own widths, for example, less than or equal to 2 μm, the widths of the reflective area and the transmissive area are considered to be equal. Those skilled in the art should understand this and set the width difference range according to actual application requirements, which will not be elaborated here.

[0056] In an optional embodiment, in the first direction, the thickness of the reflective layer in the reflective area is equal to the thickness of the lens layer in the transmissive area.

[0057] In this embodiment, to further ensure uniform heights of the reflective area and the transmissive area, the thickness of the lens layer is set to be the same as the thickness of the reflective layer. Specifically, the lens thickness of the lens layer is set to be the same as the thickness of the reflective layer.

[0058] In a specific embodiment, Figure 2 As shown, the lens layer includes a plurality of Fresnel lenses arranged in an array, and the diameter of the lenses is:

[0059]

[0060] Wherein, b is the diameter of the lens, x is the sum of the widths of the transmission area and the reflection area of ​​the sub-pixel unit, d is the distance between two adjacent lenses, n is the number of lenses of the sub-pixel unit, and n is an integer greater than or equal to 2.

[0061] In this embodiment, if Figure 2 As shown, the cross-sectional width of the sub-pixel unit is x, and the widths of the reflective area 20 and the transmissive area 30 are equal, both being The thickness of the reflective layer is the same as the thickness of the lens, both of which are a. The lens layer includes n lenses, and the distance between adjacent lenses is d, then the diameter of the lens can be calculated. Taking a specific example, the cross-sectional width x of the sub-pixel unit is 60μm, n is 4, and d is 1μm. At this time, the maximum diameter b of the lens is 6.75μm.

[0062] In a specific example, Figure 3 and Figure 4 As shown, the lens includes a central portion and a plurality of concentric rings surrounding the central portion, and the diameter of the central portion of the lens is:

[0063]

[0064] Wherein, r is the diameter of the central part, and b is the diameter of the lens;

[0065] The tooth depth of each concentric ring is equal, and the tooth depth is:

[0066]

[0067] Wherein, c is the depth of the tooth pattern, and a is the thickness of the lens layer.

[0068] In this embodiment, the Fresnel lens includes a relatively smooth central portion and a plurality of concentric rings surrounding the central portion, wherein the maximum diameter of the central portion is r, that is, the diameter of the innermost circle is r. When r is less than or equal to When the concentric rings have the same depth of tooth grooves, the multiple concentric rings collimate and converge the emitted backlight, for example, light 1 and light 2 from the backlight source pass through the tooth grooves of the concentric rings to form converged light; at the same time, the multiple concentric rings reflect the incident ambient light, for example, light 3 and light 4 from the external ambient light pass through the tooth grooves of the concentric rings to be reflected in the display device to reuse the light. Specifically, when the diameter b of the lens is 6.75μm, the diameter of the innermost circle is less than or equal to 2.25μm, and when the thickness of the lens is 2μm, the depth of each tooth groove is less than or equal to 1μm. In this embodiment, the light is accumulated by the Fresnel lens, on the one hand, the backlight incident to the transmission area is collimated and converged, and on the other hand, the external ambient light is reflected, so that the backlight and the external ambient light are integrated and comprehensively utilized through the lens, and the brightness of the transmission area is improved while the light utilization rate is improved.

[0069] In an optional embodiment, the reflective layer is a metal reflective layer, and a surface of the reflective layer away from the substrate is a concave-convex structure or a wavy structure.

[0070] In this embodiment, the reflective layer is made of metal material to improve the reflective effect, for example, the reflective layer is made of metal silver Ag or metal aluminum Al. To further improve the reflectivity of the reflective layer, the surface of the reflective layer away from the substrate is set to a non-flat surface, for example, a surface with a concave-convex structure or a surface with a wavy structure, thereby effectively improving the reflection efficiency of the external ambient light.

[0071] In an optional embodiment, the reflective region further includes a second electrode disposed between the driving circuit layer and the reflective layer, and the second electrode is electrically connected to the second thin film transistor.

[0072] In this embodiment, the second thin film transistor driving the liquid crystal in the reflective area is powered by the second electrode arranged in the reflective area, that is, the second thin film transistor is electrically connected through the second electrode arranged between the reflective layer and the driving circuit, thereby driving the thin film transistor in the reflective area.

[0073] In another optional embodiment, the reflective layer is multiplexed as a second electrode for driving the second thin film transistor and is electrically connected to the second thin film transistor.

[0074] In this embodiment, considering that the reflective layer is made of metal material, the reflective layer is reused as a second electrode for supplying power to the second thin film transistor, thereby simplifying the structure of the array substrate and reducing the manufacturing cost.

[0076] In this embodiment, the liquid crystal display panel controls the encapsulated liquid crystal layer through the array substrate and the box substrate set in the box, and forms a flat array substrate through the reflection area 20 and the transmission area 30 of equal thickness on the array substrate, wherein the reflection area includes a driving circuit layer 21 and a reflection layer 22 set on the substrate 10, and the transmission area includes a first electrode 31 and a lens layer 32 set on the substrate 10, which effectively improves the brightness of the light output from the transmission area 30, balances the brightness of the light incident from the array substrate to the liquid crystal layer, and thus improves the display effect of the display panel.

[0077] Similarly, based on the above display panel, an embodiment of the present application further provides a display device, such as Figure 8 As shown, it includes a backlight source 60 and the above-mentioned display panel arranged on the light emitting side of the backlight source 60.

[0078] In this embodiment, the liquid crystal display device is a semi-transmissive and semi-reflective display device, which reflects incident ambient light in the reflective area, collimates and converges the backlight emitted by the backlight source in the transmissive area through a lens, and reflects external ambient light, thereby increasing the brightness of the light emitted from the transmissive area, balancing the brightness of the light incident on the liquid crystal layer from the array substrate, and thus improving the display effect of the liquid crystal display device.

[0079] Corresponding to the array substrate provided in the above embodiment, an embodiment of the present application further provides a method for manufacturing the above array substrate, such as Figure 5 As shown, including:

[0080] A driving circuit layer and a reflecting layer are sequentially formed on the substrate in the reflecting area, wherein the driving circuit layer includes a first thin film transistor for driving the liquid crystal molecules in the transmitting area and a second thin film transistor for driving the liquid crystal molecules in the reflecting area;

[0081] A first electrode layer and a lens layer are sequentially formed on the substrate in the transmission area, the first electrode layer is electrically connected to the first thin film transistor, and the lens layer includes a plurality of lenses for adjusting the brightness of light emitted from the transmission area.

[0082] In this embodiment, a lens layer for adjusting the brightness of light emitted from the transmission area is provided on the transmission area, so that the brightness of light emitted from the transmission area is consistent with that of light emitted from the reflection area. Specifically, the backlight entering the transmission area is collimated by the lens of the lens layer, and the ambient light entering the transmission area is reflected, which can improve the brightness of the transmission area, thereby compensating for the problems existing in the prior art, effectively improving the display effect of the display device, and having practical application value.

Figure 6b As shown, a lens material layer 320 is formed on the first electrode layer 31, and the lens material layer is a resin material. In this embodiment, the lens material layer is a photoresist. Figure 6cAs shown, the lens material layer 320 is patterned to form a plurality of cylindrical lens substrates 321; Figure 6d As shown, the cylindrical lens substrate 321 is heat-melted to form a lens 322. Thus, a transmission area is formed.

[0089] In an optional embodiment, the driving circuit layer of the reflective layer includes a plurality of film layers, and while forming the driving circuit layer, a mask template of the film layer of the driving circuit layer is reused to form the lens.

[0090] In this embodiment, considering that a mask is needed to make multiple film layers in the driving circuit layer, the existing mask is reused to form the lens, that is, the driving circuit layer in the reflective area and the lens layer in the transmissive area are made at the same time, thereby further simplifying the production steps and reducing the production cost.
