Description

Technical Field

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

[0002] Transparent displays are widely used in the commercial sector due to their combined advantages of transparency and display. However, their transparency means that information is visible on both the light-emitting and backlighting sides. Furthermore, transparent displays have limitations when displaying certain images, thus failing to meet users' display and privacy needs and restricting their application scenarios. Summary of the Invention

[0003] In view of this, embodiments of this application provide a display module and display device to improve the display effect of a transparent display screen.

[0004] A display module includes a display panel and a transmittance controllable component. The display panel includes a first transparent region. The transmittance controllable component is located on the light-emitting side of the display panel, and / or on the backlight side of the display panel. The transmittance controllable component includes a first region. Along the stacking direction of the display panel and the transmittance controllable component, the first transparent region and the first region at least partially overlap. The display module's operating states include a first state and a second state. When the display module is in the first state, the transmittance of the transmittance controllable component in the first region is a first transmittance; when the display module is in the second state, the transmittance of the transmittance controllable component in the first region is a second transmittance, wherein the first transmittance is greater than the second transmittance.

[0005] Secondly, embodiments of this application also provide a display module, including: a display panel and a transmittance controllable component. The display panel includes a first transparent area and a first non-transparent area. The transmittance controllable component is located on the backlight side of the display panel, and includes a first area and a second area. Along the stacking direction of the display panel and the transmittance controllable component, the first area and the first transparent area at least partially overlap, and the second area covers the first non-transparent area.

[0006] Among them, the transmittance of the transmittance controllable component in the second region is less than or equal to the transmittance of the transmittance controllable component in the first region, and the transmittance of the transmittance controllable component in the second region is always less than the first threshold. The first threshold is the transmittance critical value that causes adverse effects on the internal circuits of the display panel when external light enters the display panel from the backlight side.

[0007] Thirdly, embodiments of this application also provide a display device, which includes the display modules of the first aspect and the second aspect.

[0008] In this embodiment, the first transmittance is greater than the second transmittance, which causes a difference in the transmittance of the display information or external light passing through the first area of ​​the transmittance controllable component. This enables the display module to operate with two types of display information or external light having different transmittances, thereby changing the transmittance of external light passing through the transmittance controllable component. This reduces the interference of light on the display in strong light environments, thereby improving the display effect. Attached Figure Description

Detailed Implementation

[0029] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0030] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0031] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0032] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0033] In the description of this specification, it should be understood that the terms "substantially", "approximately", "about", "about", "generally", "largely" used in the claims and embodiments of this application refer to values ​​that can be generally agreed upon within a reasonable range of process operations or tolerances, rather than a precise value.

[0034] It should be understood that although terms such as first, second, third, etc., may be used to describe regions in the embodiments of this application, these regions should not be limited to these terms. These terms are only used to distinguish regions from each other. For example, without departing from the scope of the embodiments of this application, a first region may also be referred to as a second region, and similarly, a second region may also be referred to as a first region.

[0035] The defining characteristic of transparent display panels is their ability to display information transparently. However, most transparent display panels can only display information transparently and cannot achieve non-transparent displays. In strong light environments, the intense ambient light makes it difficult to clearly see the displayed content, severely impacting the user's viewing experience. Furthermore, the transparent nature of these panels means that information can be seen from both the light-emitting and backlighting sides, thus affecting the user's privacy needs.

[0036] To achieve transparent display while controlling production costs, the backlight side of the transparent display panel is also transparent. This allows external light to enter the interior of the transparent display panel from the backlight side, illuminating the semiconductor devices inside. However, prolonged exposure to light, especially long-term exposure, can cause the semiconductor properties to shift, thus affecting the display performance.

[0037] Through meticulous and in-depth research, the applicant in this case has provided a solution to the problems existing in the prior art.

[0038] Figure 1 is a schematic diagram of a display module provided in an embodiment of this application.

[0039] like Figure 1a , Figure 2a and Figure 3aAs shown in the figure, this application embodiment provides a display module 100, including: a display panel 110 and a transmittance controllable component 120. The display panel 110 includes a first transparent region A1. It should be understood that the display panel 110 is a transparent display panel.

[0040] The transmittance of the transmittance controllable component 120 is controllable, meaning its transmittance can be controlled based on actual needs. In one possible implementation, the transmittance of the transmittance controllable component 120 can be controlled and adjusted based on actual needs by adjusting its electrical parameters (e.g., voltage). The transmittance controllable component 120 is located on at least one side of the display panel 110. The transmittance controllable component 120 includes a first region B1. Along the stacking direction of the display panel 110 and the transmittance controllable component 120, the first transparent region A1 and the first region B1 at least partially overlap.

[0041] like Figure 1a , Figure 2a and Figure 3a As shown, in one possible implementation, the transmittance controllable component 120 is located on the light-emitting side of the display panel 110. And / or the transmittance controllable component 120 is located on the backlight side of the display panel 110.

[0042] The operating states of the display module 100 include a first state and a second state. For example... Figure 1a , Figure 2a and Figure 3a As shown, when the display module 100 is in the first state, the transmittance of the transmittance controllable component 120 in the first region B1 is the first transmittance. Figure 1b , Figure 2b and Figure 3b As shown, when the display module 100 is in the second state, the transmittance of the transmittance controllable component 120 in the first region B1 is the second transmittance. The first transmittance is greater than the second transmittance.

[0043] In this embodiment, the transmittance of the transmittance controllable component 120 in the first region B1 is adjustable, and the first transmittance is greater than the second transmittance. This results in a difference in the transmittance of the display information of the display panel 110 or external light passing through the first region B1 of the transmittance controllable component 120. This enables the display module 100 to operate in a state where the two types of display information or external light have different transmittances. This changes the transmittance of external light passing through the transmittance controllable component 120, thereby reducing the interference of light on the display in strong light environments and improving the display effect.

[0044] In one possible implementation, the first state is a transparent display state, and the second state is a non-transparent display state.

[0045] like Figure 1a and Figure 1b As shown, in one possible implementation, the transmittance controllable component is located on the backlight side of the display panel 110. The first transmittance is greater than or equal to 70%, and the second transmittance is less than or equal to 50%. That is, the first state is a transparent state, and the second state is an opaque state. Therefore, the transmittance controllable component 120 can be used to realize the conversion between transparent display and opaque display, thereby improving the shortcomings of transparent display: for example, in a strong light environment, the strong light can be limited to pass through the display module by making the display module work in the second state, thus effectively improving the display effect in a strong light environment; for another example, by making the display module work in the second state, people on the backlight side can be prevented from obtaining the display information, thereby improving the privacy protection; if transparent display is required, it is only necessary to make the display module 100 work in the first state.

[0046] like Figure 2a and Figure 2b As shown, in one possible implementation, along the stacking direction of the display panel 110 and the transmittance controllable component 120, the first region B1 and the first transparent region A1 partially overlap. The transmittance controllable component 120 is located on the light-emitting side of the display panel 110, and includes a plurality of transparent holes C1. The minimum distance between the transparent holes C1 and the first region B1 is greater than or equal to zero, and the transparent holes C1 and the first region B1 do not intersect. The display panel 110 includes pixel units, and along the stacking direction of the display panel 110 and the transmittance controllable component 120, the pixel units are located within the transparent holes C1. When the display module 100 is in the working state, the transmittance controllable module within the transparent holes C1 is in a constant transparent state.

[0047] In one possible implementation, the transmittance controllable component within the transparent region C1 is a transparent component, and the transmittance of the transparent component remains stable. It should be noted that the stable transmittance of the transparent component is relative, meaning that its transmittance will not change with external conditions. However, changes in transmittance due to oxidation, weathering, or aging of the material itself fall within the scope of stable transmittance described in this embodiment.

[0048] In one possible implementation, the transmittance of the transmittance controllable component 120 within the transparent area C1 can be adjusted. When the display module is in operation, the transmittance of the transmittance controllable component 120 within the transparent area C1 is greater than a transparency threshold. The transparency threshold refers to a value at which the transmittance controllable component 120 can be considered transparent. For example, the transparency threshold is 70%.

[0049] When the transmittance of the controllable transmittance component in the first region B1 is at the first transmittance, it can increase the transmission rate of external light, such as enabling transparent display; when the transmittance of the controllable transmittance component 120 in the first region is at the second transmittance, it can prevent strong light from passing through the display module 100, thereby reducing the negative impact of strong light environment on display effect.

[0050] like Figure 3a and 3b As shown, in one possible implementation, the display module 100 includes two transmittance controllable components 120. One of the two transmittance controllable components 120 is located on the light-emitting side of the display panel 110, and the other is located on the backlight side of the display panel 110.

[0051] In one possible implementation, two transmittance controllable components 120 are used, one being a first transmittance controllable component 120a and the other a second transmittance controllable component 120b. The first transmittance controllable component 120a is located on the light-emitting side of the display panel 110. The second transmittance controllable component 120b is located on the backlight side of the display panel 110. The first transmittance controllable component 120a includes a transparent area C1, and the display panel 110 includes pixel units. Along the stacking direction of the display panel 110 and the transmittance controllable component 120, the pixel units are located within the transparent aperture C1. In the first transmittance controllable component 120a, the minimum distance between its first region B1a and the transparent aperture C1 is greater than or equal to zero, and the transparent aperture C1 and the first region B1 do not intersect. Along the stacking direction Z of the display panel 110 and the transmittance controllable component 120, the first region B1b of the second transmittance controllable component 120b covers the first transparent region A1 of the display panel 110, and the second transmittance controllable component 120b covers the first transmittance controllable component 120a. The transmittance of the first transmittance controllable component 120a is equal to the transmittance of the second transmittance controllable component 120b. "Equally corresponding" means that their positions are equal; along the stacking direction Z of the display panel 110 and the transmittance controllable component 120, the two transmittance controllable components 120 are positioned equally on the same straight line L. The straight line L is parallel to the direction Z. The equal transmittance of the two transmittance controllable components 120 facilitates control.

[0052] In one possible implementation, the transmittance controllable component is located on the backlight side of the display panel 110, and along the stacking direction of the display panel 110 and the transmittance controllable component 120, the first region B1 and the first transparent region A1 completely overlap.

[0053] In this implementation, the first region B1 and the first transparent region A1 completely overlap, which not only does not affect the transparent display effect, but also effectively protects the pixel circuits in the first transparent region from external light damage.

[0054] In one possible implementation, the transmittance controllable component 120 maintains a constant transmittance within the first region B1. That is, the transmittance is equal at any two points within the controllable component 120 within the first region B1. Therefore, the transmittance controllable component 120 within the first region B1 can be uniformly controlled, thereby reducing the difficulty and complexity of control.

[0055] like Figure 4 As shown, in one possible implementation, the transmittance controllable component 120 further includes a second region B2, which is adjacent to the first region B1. Along the stacking direction of the display panel 110 and the transmittance controllable component 120, the second region B2 does not overlap with the first transparent region A1.

[0056] When the display module 100 is in the first state, the transmittance of the transmittance controllable component 120 in the first region B1 is greater than the transmittance of the transmittance controllable component 120 in the second region B2.

[0057] In one possible implementation, the transmittance of the transmittance controllable component 120 within the second region B2 is constant. That is, the transmittance of the transmittance controllable component 120 within the second region B2 is independent of the operating state of the display module 100. For example, the transmittance controllable component 120 within the second region B2 is transparent glass. Alternatively, the transmittance of the transmittance controllable component 120 within the second region B2 is controllable, but the control conditions for the transmittance controllable component 120 within the second region B2 are constant, such as connecting a constant voltage electrical signal.

[0058] In one possible implementation, when the display module 100 is in the second state, the transmittance of the transmittance controllable component 120 in the first region B1 is equal to the transmittance of the transmittance controllable component 120 in the second region B2.

[0059] like Figure 5 or Figure 6 As shown in one embodiment of this application, the first region B1 includes a first sub-region B11 and a second sub-region B12. The first sub-region B11 at least partially surrounds the second sub-region B12. Along the stacking direction of the display panel 110 and the transmittance controllable component 120, a first transparent region A1 covers the second sub-region B12. When the display module 100 is in a first state, the transmittance of the transmittance controllable component 120 in the first sub-region B11 is less than the transmittance of the transmittance controllable component 120 in the second sub-region B12.

[0060] Among them, Figure 5 The first subregion B11 partially surrounds the second subregion B12; in Figure 6 In the middle, the first sub-region B11 surrounds the second sub-region B12.

[0061] In this embodiment, the transmittance of the transmittance controllable component 120 in the first sub-region B11 is less than that in the second sub-region B12, which helps to achieve a gradual change in transmittance from the first sub-region B11 to the second sub-region B12, and helps to reduce the negative impact of diffraction effects on the display effect under strong light environment.

[0062] like Figure 1a and 2a As shown, in one embodiment of this application, the shape of the first transparent region A1 is the same as the shape of the first region B1.

[0063] In this embodiment, the shape of the first transparent region A1 is the same as the shape of the first region B1 to facilitate matching, increase the light-transmitting area, and improve the transparent display effect. For example, in one possible implementation, the shape of the first transparent region A1 is circular, and the shape of the first region B1 is also circular. The circular shape of the first transparent region A1 can help optimize light diffraction, thereby improving the display effect.

[0064] like Figure 5 or Figure 6 As shown, in one embodiment of this application, the first transparent area A1 is polygonal in shape, and the second sub-area B12 displays edges that include at least curved edges.

[0065] In this embodiment, the polygonal shape of the first transparent region A1 effectively increases the light-transmitting area and improves the transparent display effect; for example, the rectangular shape of the first transparent region A1. The second sub-region B12's display edge includes at least a curved edge, which helps to optimize the adverse effects of light diffraction.

[0066] In one possible implementation, the second sub-region B12 is circular or elliptical in shape. Circular or elliptical shapes are easy to manufacture and can reduce production costs while minimizing the adverse effects of light diffraction.

[0067] Combination Figure 1a and Figure 7 In one embodiment of this application, the shape of the first transparent region A1 is the same as the shape of the first region B1. The shape of the first transparent region A1 is a polygon, and the shape of the second sub-region B12 is a polygon. The number of sides of the shape of the second sub-region B12 is greater than the number of sides of the shape of the first transparent region A1.

[0068] In this embodiment, having more sides than the first transparent region A1 helps optimize light diffraction and improve display quality. For example, the first transparent region A1 can be rectangular, and the second sub-region B12 can be a regular octagon, a regular dodecagon, or a regular hexagon. The greater the difference between the number of sides of the second sub-region B12 and the first transparent region A1, the better the effect on optimizing light diffraction. In one possible implementation, the difference between the number of sides of the second sub-region B12 and the first transparent region A1 is greater than or equal to 4, for example, 8.

[0069] Combination Figures 4 to 6 In one embodiment of this application, the transmittance controllable component 120 further includes a second region B2, which is adjacent to the first region B1. Along the stacking direction of the display panel 110 and the transmittance controllable component 120, the second region B2 does not overlap with the first transparent region A1. When the display module 100 is in a first state, the transmittance of the transmittance controllable component 120 in the first sub-region B11 is a1, the transmittance of the transmittance controllable component 120 in the second sub-region B12 is a2, and the transmittance of the transmittance controllable component 120 in the second region B2 is a3. Wherein, a3 ≤ a1 < a2.

[0070] In one possible implementation of this embodiment, a3 = a1 < a2. That is, the transmittance of the transmittance controllable component 120 in the second region is synchronized with the transmittance controllable component 120 in the second sub-region B12. This facilitates uniformity of the display effect and reduces the control difficulty of the transmittance controllable component 120, thereby reducing product costs. This implementation is suitable for scenarios where diffraction does not affect the display effect of the display module.

[0071] In one possible implementation of this embodiment, a3 < a1 < a2. Therefore, the first sub-region B11, the second sub-region B12, and the second region A2 achieve a gradient in transparency, thus enabling a gradient display effect. This increases the number of display types and expands the applicability of the display module 100. This implementation is suitable for scenarios where diffraction has affected or severely affected the display effect of the display module.

[0072] Furthermore, in this implementation, a3 < a2 < a1. Therefore, the transmittance of the first sub-region B11 and the second sub-region B12 is different. This difference in transmittance can further highlight the beneficial effects brought about by the shape of the first sub-region B11. For example, if the shape of the first sub-region B11 is circular, the difference in transmittance between the first sub-region B11 and the second sub-region B12 makes the boundary between the first sub-region B11 and the second sub-region B12 more distinct, thereby better demonstrating the optimization effect of the circle on light diffraction.

[0073] like Figure 4 As shown, in one embodiment of this application, the display panel 110 includes a first non-transparent region A2. Along the stacking direction of the display panel 110 and the transmittance controllable component 120, the first non-transparent region A2 and the second region B2 at least partially overlap. The transmittance of the transmittance controllable component 120 in the second region B2 when the display module 100 is in the first state is equal to the transmittance of the transmittance controllable component in the second region B2 when the display module 100 is in the second state.

[0074] In this embodiment, the transmittance of the transmittance controllable component 120 in the second region B2 when the display module 100 is in the first state is equal to the transmittance of the transmittance controllable component in the second region B2 when the display module 100 is in the second state. That is, the transmittance of the transmittance controllable component 120 in the second region B2 does not change with the operating mode of the display module 100. In a specific implementation of this embodiment, this can be achieved by not energizing the transmittance controllable component 120, thereby reducing power consumption and simplifying control complexity.

[0075] In this first embodiment, when the display module 100 is in operation, the transmittance of the transmittance controllable component 120 in the second region B2 remains stable. Here, "stable transmittance" is relative, meaning that its transmittance does not change with external conditions. However, changes in transmittance due to material oxidation, weathering, or aging fall within the scope of "stable transmittance" described in this embodiment.

[0076] like Figures 8 to 11 As shown, in one embodiment of this application, the transmittance controllable component 120 includes: a first electrode 121, a second electrode 122 and a transmittance controllable material 123. Along the stacking direction of the display panel 110 and the transmittance controllable component 120, the transmittance controllable material 123 is located between the first electrode 121 and the second electrode 122.

[0077] like Figure 8 As shown, in one possible implementation, the transmittance controllable component 120 is located on the backlight side of the display panel 110. The first electrode 121 in the first region B1 is a solid surface structure. The second electrode 122 in the first region B1 is a solid surface structure. The transmittance controllable material 123 in the first region B1 is a solid surface structure. A solid surface structure means that the structure in its region is continuously formed into a single surface.

[0078] This implementation method enables the display module to increase the transmittance of the controllable transmittance component 120 in the first region B1 when transparent display is required, thereby achieving transparent display.

[0079] like Figure 9 As shown, in one possible implementation, the first electrode 121 includes a first sub-electrode 1211 and a second sub-electrode 1212, wherein the first sub-electrode 1211 is located in a first sub-region B11, the second sub-electrode 1212 is located in a second sub-region B12, and the first sub-electrode 1211 and the second sub-electrode 1212 are electrically insulated from each other.

[0080] In this embodiment, the transmittance of the transmittance controllable component 120 can be controlled by adjusting the voltage between the first electrode 121 and the second electrode 122. The first sub-electrode 1211 and the second sub-electrode 1212 are electrically insulated, enabling independent control of the transmittance controllable component 120 within the first sub-region B11 and the first sub-region B12, thereby achieving independent controllability of the transmittance within the first sub-region B11 and the second sub-region B12.

[0081] like Figure 9 As shown, in one possible implementation, the second electrode 122 is a full-surface structure.

[0082] In this implementation, the second electrode 122 is a solid surface structure and does not require patterning, thereby simplifying the process, reducing the process flow, and saving costs.

[0083] like Figure 10 As shown, in one possible implementation, along the stacking direction of the display panel 110 and the transmittance controllable component 120, the projected shape of the first electrode 121 is the same as the projected shape of the second electrode 122 and the area is equal.

[0084] The projection of the first electrode 121 has the same shape as the projection of the second electrode 122, which enables completely independent control of the first sub-region B11, the second sub-region B12, and the second region B2.

[0085] In this embodiment, the light transmittance controllable material 123 can be as follows: Figure 9 or Figure 10 The full-surface structure shown can be as follows: Figure 11 The patterned structure shown. Figure 11 Along the stacking direction of the display panel 110 and the transmittance controllable component 120, the projection shape of the first electrode 121, the projection shape of the second electrode 122, and the projection shape of the transmittance controllable material 123 are the same and have the same area.

[0086] like Figure 12As shown, in one embodiment of this application, the display panel 110 further includes a first non-transparent region A2, and the transmittance controllable component 120 further includes a second region B2. Along the stacking direction of the display panel 110 and the transmittance controllable component 120, the second region B2 covers the first non-transparent region A2. The transmittance of the transmittance controllable component 120 within the second region B2 is constant and always less than a first threshold. The first threshold is a critical transmittance value at which external light entering the display panel from the backlight side causes adverse effects on the internal circuitry of the display panel. In one possible implementation, the first threshold is 40%-70%, for example, 50%.

[0087] In one possible implementation of this embodiment, the transmittance controllable component 120 is located on the backlight side of the display panel 110. The transmittance of the transmittance controllable component 120 in the second region B2 is constant and always less than a first threshold, which can effectively limit external light from entering the display panel from the backlight side, thereby protecting the pixel circuit located in the first non-transparent area and increasing the stability of the display.

[0088] like Figure 12 As shown, in one possible implementation, the edge shape of the second region B2 includes an arc shape. The arc shape of the edge shape of the second region B2 can optimize the negative effects of light diffraction.

[0089] like Figure 12 As shown, in one possible implementation, the second region B2 includes a first edge B21 and a second edge B22, with the first edge B21 surrounding the second region B2. The second edge B22 is located inside the first edge B21. The second edge B22 is a closed edge, and the area surrounded by the second edge B21 partially overlaps with a portion of the first region. The second edge B22 is composed of multiple arcs. In one possible implementation, the second edge B22 is composed of multiple circular arcs connected end-to-end in sequence.

[0090] like Figures 9 to 11 As shown, in one embodiment of this application, the transmittance controllable component 120 includes a first electrode 121, a second electrode 122, and a transmittance controllable material 123. Along the stacking direction of the display panel 110 and the transmittance controllable component 120, the transmittance controllable material 123 is located between the first electrode 121 and the second electrode 122. The first electrode 121 includes a first sub-electrode 1211 and a third sub-electrode 1213. The first sub-electrode 1211 is located within a first region B1, and the third sub-electrode 1213 is located within a second region B2. The third sub-electrode 1213 is electrically insulated from the first sub-electrode 1211.

[0091] In this embodiment, the third sub-electrode 1213 is electrically insulated from the first sub-electrode 1211, enabling independent control of the transmittance controllable component 120 in the second region B2 and the first region B1, thereby making the transmittance of the transmittance controllable component 120 in the second region B2 different from that in the first region B1.

[0092] like Figure 9 As shown, in one embodiment of this application, the first electrode 121 further includes a second sub-electrode 1212. The first sub-electrode 1211 is located within a first sub-region B11, the second sub-electrode 1212 is located within a second sub-region B12, the first sub-electrode 1211 and the second sub-electrode 1212 are electrically insulated from each other, and the second sub-electrode 1212 is electrically insulated from the third sub-electrode 1213.

[0093] In this embodiment, independent partitioning control of the first sub-region, the second sub-region, and the second region is achieved, thereby enabling each region to have its own transmittance.

[0094] In one embodiment of this application, the transmittance controllable material 123 includes at least one of electrochromic material, polymer network liquid crystal, or polymer dispersed liquid crystal.

[0095] In one possible implementation, the transmittance controllable material 123 includes one of an electrochromic material, a polymeric liquid crystal network, or a polymeric dispersed liquid crystal. An electrochromic material is one that changes color under an electric field, for example, by changing its transparency, thereby altering its transmittance. A polymeric liquid crystal network or polymeric dispersed liquid crystal is a liquid crystal material that can change its crystal alignment angle under the influence of voltage, thereby changing its transmittance.

[0096] In one possible implementation, the transmittance-controllable material includes at least two of the following: electrochromic materials, polymeric liquid crystal networks (PLNs), or polymeric dispersed liquid crystals. For example, the transmittance-controllable material in the first region is a PLC or a PLC, while the transmittance-controllable material in the second region is an electrochromic material. This implementation offers greater flexibility, thereby helping to save costs.

[0097] like Figure 12 and 13As shown, this application also provides a display module 100 including: a display panel 110 and a transmittance controllable component 120. The display panel 110 includes a first transparent region A1 and a first non-transparent region A2. The transmittance controllable component 120 is located on the backlight side of the display panel 110, and includes a first region B1 and a second region B2. Along the stacking direction of the display panel 110 and the transmittance controllable component 120, the first region B1 at least partially overlaps with the first transparent region A1, and the second region B2 covers the first non-transparent region A2.

[0098] The transmittance of the transmittance controllable component in the second region B2 is less than or equal to the transmittance of the transmittance controllable component 120 in the first region B1, and the transmittance of the transmittance controllable component 120 in the second region B2 is always less than the first threshold. The first threshold is the transmittance critical value that causes adverse effects on the internal circuitry of the display panel 110 when external light enters the display panel 110 from the backlight side.

[0099] In this embodiment, the transmittance of the controllable component in the second region B2 is low and always below the first threshold, which can effectively limit external light from entering the display panel from the backlight side, thereby helping to prevent the pixel driving circuit of the display panel 110 from being affected by external light and ultimately ensuring the stability of the display effect.

[0100] like Figure 12 As shown, in one embodiment of this application, the edge shape of the second region B2 includes an arc shape. The arc shape of the edge shape of the second region B2 can optimize the negative effects of light diffraction.

[0101] like Figure 12 As shown, in one possible implementation, the second region B2 includes a first edge B21 and a second edge B22, with the first edge B21 surrounding the second region B2. The second edge B22 is located inside the first edge B21. The second edge B22 is a closed edge, and the area surrounded by the second edge B21 partially overlaps with a portion of the first region. The second edge B22 is composed of multiple arcs. In one possible implementation, the second edge B22 is composed of multiple circular arcs connected end-to-end in sequence.

[0102] like Figure 13 As shown, in one possible implementation, the shape of the second region is a circle, an ellipse, or a polygon.

[0103] In this embodiment, the shape of the second region is circular, elliptical, or polygonal, which helps to optimize the negative impact of light diffraction on the display effect.

[0104] In this embodiment, the transmittance controllable component in the first region can be the transmittance controllable component in the first region provided in any of the foregoing embodiments.

[0105] In one embodiment of this application, the transmittance of the transmittance controllable component in the first region is constant.

[0106] The transmittance of the transmittance controllable component in the first region is constant, which helps to reduce the difficulty of controlling the transmittance controllable component 120, thereby helping to reduce costs.

[0107] In one possible implementation, the transmittance controllable component within the first region B1 includes a transparent material. The transparent material can be transparent glass. Using transparent glass as the transparent material can eliminate control costs and reduce the complexity of the display module 100.

[0108] like Figure 14 As shown, this application embodiment also provides a display device 200, which includes the display module 100 provided in any of the foregoing embodiments.

[0109] The display device provided in this application embodiment has good display effect and can help reduce the adverse effects of light on display effect.

[0110] Furthermore, due to its light transmittance, the internal pixel circuits of a transparent display are exposed to light for extended periods. Prolonged exposure to light can cause the transistor characteristics of the pixel circuits in a transparent display to drift, resulting in unstable display performance and, in severe cases, display malfunctions.

[0111] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
