[0011] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0012] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0013] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0014] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0015] In the description of this specification, it is necessary to understand that the words such as "substantially", "approximately", "approximately", "about", "roughly", "substantially" and the like described in the claims and embodiments of the present application refer to what can be generally recognized within a reasonable process operation range or tolerance range, rather than an exact value.

[0016] It should be understood that although the terms first, second, third, etc. may be used to describe regions, etc. in the embodiments of the present application, these regions, etc. should not be limited to these terms. These terms are only used to distinguish regions, etc. from each other. For example, without departing from the scope of the embodiments of the present application, the first region may also be referred to as the second region, and similarly, the second region may also be referred to as the first region.

[0017] The characteristic of transparent display panels is that they can display transparently. Most transparent display panels can only display transparently, and cannot display non-transparently. When transparent display is performed in a strong light environment, the display content cannot be clearly viewed due to the strong external light, which seriously affects the viewing experience of consumers. Moreover, the transparent display of transparent display panels can see the display information on both the light-emitting side and the backlight side, which affects the privacy needs of consumers.

[0018] In order to realize the transparent display of the transparent display panel and control the production cost, the backlight side of the transparent display panel is also transparent. As a result, external light can enter the interior of the transparent display panel from the backlight side and cause the semiconductor devices inside the transparent display panel to be exposed to light. If the semiconductor devices inside the transparent display panel are exposed to light for a long time, especially long-term light exposure, the characteristics of the semiconductor will drift, thereby affecting the display effect.

[0019] The applicant in this case has provided a solution to the problems existing in the prior art through careful and in-depth research.

[0020] FIG. 1 is a schematic diagram of a display module provided in an embodiment of the present application.

[0021] like Figure 1a , Figure 2a and Figure 3a As shown, the embodiment of the present application provides a display module 100, including: a display panel 110 and a transmittance controllable component 120. The display panel 110 includes a first transparent area A1. It should be understood that the display panel 110 is a transparent display panel.

[0022] The transmittance of the controllable transmittance component 120 is controllable, that is, the transmittance of the controllable transmittance component 120 can be controlled based on actual needs. In a possible implementation, the transmittance of the controllable transmittance component 120 can be controlled and adjusted by adjusting its electrical parameters (such as voltage) based on actual needs. The controllable transmittance component 120 is located on at least one side of the display panel 110. The controllable transmittance component 120 includes a first area B1. Along the stacking direction of the display panel 110 and the controllable transmittance component 120, the first transparent area A1 at least partially overlaps with the first area B1.

[0023] like Figure 1a , Figure 2a and Figure 3a As shown, in a possible implementation, the controllable transmittance component 120 is located on the light emitting side of the display panel 110 , and / or the controllable transmittance component 120 is located on the backlight side of the display panel 110 .

[0024] The working state of the display module 100 includes a first state and a second state. Figure 1a , Figure 2a and Figure 3a As shown, when the display module 100 is in the first state, the transmittance of the controllable transmittance component 120 in the first area 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 controllable transmittance component 120 in the first area B1 is the second transmittance. The first transmittance is greater than the second transmittance.

[0025] In this embodiment, the transmittance of the transmittance controllable component 120 in the first area B1 is adjustable, and the first transmittance is greater than the second transmittance, so that the display information of the display panel 110 or the transmittance of external light passing through the first area B1 of the transmittance controllable component 120 is different, thereby realizing that the display module 100 includes two display information or external light having different transmittances. The transmittance of the external light passing through the transmittance controllable component 120 can be changed, thereby reducing the interference of light on the display in a strong light environment, thereby achieving the purpose of improving the display effect.

[0026] In a possible implementation manner, the first state is a transparent display state, and the second state is a non-transparent display state.

[0027] like Figure 1a and Figure 1b As shown, in a 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 a non-transparent state. Therefore, the use of the transmittance controllable component 120 can realize the conversion between transparent display and non-transparent display, thereby improving the shortcomings of transparent display: for example, in a strong light environment, the display module can be operated in the second state to limit the strong light from passing through the display module, thereby effectively improving the display effect in a strong light environment; for another example, by operating the display module in the second state, people on the backlight side are prevented from obtaining display information, thereby improving privacy protection; if transparent display is required, it is sufficient to operate the display module 100 in the first state.

[0028] like Figure 2aand Figure 2b As shown, in a possible implementation, along the stacking direction of the display panel 110 and the controllable transmittance component 120, the first area B1 partially overlaps with the first transparent area A1. The controllable transmittance component 120 is located on the light-emitting side of the display panel 110, and the controllable transmittance component 120 includes a plurality of transparent holes C1, the minimum distance between the transparent hole C1 and the first area B1 is greater than or equal to zero, and the transparent hole C1 does not intersect with the first area B1. The display panel 110 includes a pixel unit, and along the stacking direction of the display panel 110 and the controllable transmittance component 120, the pixel unit is located in the transparent hole C1. When the display module 100 is in the working state, the controllable transmittance module in the transparent hole C1 is in a constant transparent state.

[0029] In a possible implementation, the transmittance controllable component in the transparent area C1 is a transparent component, and the transmittance of the transparent component is stable. It should be noted that the stable transmittance of the transparent component is relative, which means that its transmittance will not change with the conditions applied by the outside world, but the changes in transmittance caused by oxidation, weathering or aging of the material itself belong to the category of stable transmittance recorded in this embodiment.

[0030] In a possible implementation, the transmittance of the controllable transmittance component 120 in the transparent area C1 can be adjusted. When the display module is in the working state, the transmittance of the controllable transmittance component 120 in the transparent area C1 is greater than the transparency threshold. The transparency threshold means that the transmittance of the controllable transmittance component 120 is greater than or equal to the value, and the controllable transmittance component 120 can be regarded as transparent. For example, the transparency threshold is 70%.

[0031] When the transmittance of the controllable transmittance component in the first area B1 is the first transmittance, the transmittance of external light can be increased, for example, transparent display can be achieved; when the transmittance of the controllable transmittance component 120 in the first area is the second transmittance, strong light can be prevented from passing through the display module 100, thereby reducing the negative impact of the strong light environment on the display effect.

[0032] like Figure 3a and 3b As shown, in a possible implementation, the display module 100 includes two controllable transmittance components 120 . One of the two controllable transmittance 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 .

[0033] In a possible implementation, there are two controllable transmittance components 120, one of which is a first controllable transmittance component 120a, and the other is a second controllable transmittance component 120b. The first controllable transmittance component 120a is located on the light-emitting side of the display panel 110. The second controllable transmittance component 120b is located on the backlight side of the display panel 110. The first controllable transmittance component 120a includes a transparent area C1, and the display panel 110 includes a pixel unit. Along the stacking direction of the display panel 110 and the controllable transmittance component 120, the pixel unit is located in the transparent hole C1. In the first controllable transmittance component 120a, the minimum distance between its first area B1a and the transparent hole C1 is greater than or equal to zero, and the transparent hole C1 does not intersect with the first area B1. Along the stacking direction Z of the display panel 110 and the controllable transmittance component 120, the first area B1b of the second controllable transmittance component 120b covers the first transparent area A1 of the display panel 110, and the second controllable transmittance component 120b covers the first controllable transmittance component 120a. The transmittance of the first controllable transmittance component 120a corresponds to the transmittance of the second controllable transmittance component 120b. Corresponding equality means that the positions correspond to each other. Along the stacking direction Z of the display panel 110 and the controllable transmittance component 120, the positions of the two controllable transmittance components 120 on the same straight line L correspond to each other. The straight line L is parallel to the direction Z. The transmittance of the two controllable transmittance components 120 corresponds to each other for easy control.

[0034] In a possible implementation, the controllable transmittance component is located on the backlight side of the display panel 110 , and along the stacking direction of the display panel 110 and the controllable transmittance component 120 , the first area B1 completely overlaps with the first transparent area A1 .

[0035] In this implementation, the first area B1 completely overlaps with the first transparent area A1, which will not affect the transparent display effect and can effectively protect the pixel circuit in the first transparent area from being damaged by external light.

[0036] In a possible implementation, the transmittance of the controllable transmittance component 120 in the first area B1 is constant. That is, in the first area B1, the transmittances of any two locations in the controllable component 120 are equal. Therefore, the controllable transmittance component 120 in the first area B1 can be uniformly controlled, thereby reducing the control difficulty and complexity.

[0037] like Figure 4 As shown, in a possible implementation, the controllable transmittance component 120 further includes a second area B2, which is adjacent to the first area B1. Along the stacking direction of the display panel 110 and the controllable transmittance component 120, the second area B2 does not overlap with the first transparent area A1.

[0038] When the display module 100 is in the first state, the transmittance of the controllable transmittance component 120 in the first area B1 is greater than the transmittance of the controllable transmittance component 120 in the second area B2.

[0039] In a possible implementation, the transmittance of the controllable transmittance component 120 in the second area B2 is constant. That is, the transmittance of the controllable transmittance component 120 in the second area B2 is independent of the working state of the display module 100. For example, the controllable transmittance component 120 in the second area B2 is transparent glass. Or the transmittance of the controllable transmittance component 120 in the second area B2 is controllable, but the control condition of the controllable transmittance component 120 in the second area B2 is constant, for example, a constant voltage electric signal is turned on.

[0040] In a possible implementation, when the display module 100 is in the second state, the transmittance of the controllable transmittance component 120 in the first area B1 is equal to the transmittance of the controllable transmittance component 120 in the second area B2.

[0041] like Figure 5 or Figure 6 As shown, in one embodiment of the present application, the first area B1 includes a first sub-area B11 and a second sub-area B12, the first sub-area B11 at least partially surrounds the second sub-area B12, and the first transparent area A1 covers the second sub-area B12 along the stacking direction of the display panel 110 and the controllable transmittance component 120. When the display module 100 is in the first state, the transmittance of the controllable transmittance component 120 in the first sub-area B11 is less than the transmittance of the controllable transmittance component 120 in the second sub-area B12.

[0042] Among them, Figure 5 The first sub-region B11 partially surrounds the second sub-region B12; Figure 6 In the embodiment, the first sub-region B11 surrounds the second sub-region B12.

[0043] In the embodiment of the present application, the transmittance of the controllable transmittance component 120 in the first sub-area B11 is lower than the transmittance of the controllable transmittance component 120 in the second sub-area B12, which can facilitate the gradual change of transmittance from the first sub-area B11 to the second sub-area B12, and help reduce the negative impact of the diffraction effect on the display effect in a strong light environment.

[0044] like Figure 1a and 2a As shown, in one embodiment of the present application, the shape of the first transparent area A1 is the same as the shape of the first area B1.

[0045] In this embodiment, the shape of the first transparent area A1 is the same as the shape of the first area B1, which is convenient for matching, increasing the light transmission area, and improving the transparent display effect. For example, in a possible implementation, the shape of the first transparent area A1 is circular, and the shape of the first area B1 is circular. The circular shape of the first transparent area A1 can help optimize the diffraction of light, thereby improving the display effect.

[0046] like Figure 5 or Figure 6 As shown, in one embodiment of the present application, the shape of the first transparent area A1 is a polygon, and the display edge of the second sub-area B12 at least includes an arc-shaped edge.

[0047] In this embodiment, the polygonal shape of the first transparent area A1 can effectively increase the light transmission area and improve the transparent display effect. For example, the first transparent area A1 is rectangular. The second sub-area B12 display edge includes at least an arc edge, which can help optimize the adverse effects of light diffraction.

[0048] In a possible implementation, the second sub-region B12 is in a circular or elliptical shape, which is easy to realize in terms of technology, and can reduce the production cost while optimizing the adverse effects caused by light diffraction.

[0049] Combination Figure 1a and Figure 7 In one embodiment of the present application, the shape of the first transparent area A1 is the same as the shape of the first area B1, the shape of the first transparent area A1 is a polygon, and the shape of the second sub-area B12 is a polygon. The number of sides of the shape of the second sub-area B12 is greater than the number of sides of the shape of the first transparent area A1.

[0050] In this embodiment, the number of sides of the shape of the second sub-area B12 is greater than the number of sides of the shape of the first transparent area A1, which can help optimize the diffraction of light and improve the display effect. For example, the shape of the first transparent area A1 is a rectangle, and the number of sides of the shape of the second sub-area B12 is a regular octagon, a regular dodecagon, or a regular hexagon, etc. The greater the difference between the number of sides of the shape of the second sub-area B12 and the number of sides of the shape of the first transparent area A1, the better the effect of optimizing the diffraction of light. In a possible implementation, the difference between the number of sides of the shape of the second sub-area B12 and the number of sides of the shape of the first transparent area A1 is greater than or equal to 4, for example, 8.

[0051] Combination Figures 4 to 6In one embodiment of the present application, the controllable transmittance component 120 also includes a second area B2, and the second area B2 is adjacent to the first area B1. Along the stacking direction of the display panel 110 and the controllable transmittance component 120, the second area B2 does not overlap with the first transparent area A1. When the display module 100 is in the first state, the transmittance of the controllable transmittance component 120 in the first sub-area B11 is a1, the transmittance of the controllable transmittance component 120 in the second sub-area B12 is a2, and the transmittance of the controllable transmittance component 120 in the second area B2 is a3. Wherein, a3≤a1<a2.

[0052] In a possible implementation of this embodiment, a3=a1<a2. That is, the transmittance of the controllable transmittance component 120 in the second area is synchronized with the transmittance of the controllable transmittance component 120 in the second sub-area B12, which is conducive to achieving uniformity of display effect on the one hand, and can reduce the control difficulty of the controllable transmittance component 120 on the other hand, which is conducive to reducing product cost. This implementation is suitable for scenes when diffraction does not affect the display effect of the display module.

[0053] In a possible implementation of this embodiment, a3<a1<a2, so the first sub-area B11, the second sub-area B12 and the second area A2 realize a gradual change in transparency, thereby realizing a gradual display effect, thereby increasing the display types and the applicable scope of the display module 100. This implementation is suitable for scenes where diffraction has affected or seriously affected the display effect of the display module.

[0054] In addition, in the present implementation, a3<a2<a1, therefore, the transmittance of the first sub-region B11 and the second sub-region B12 are different, and this difference in transmittance can further highlight the beneficial effects brought by the shape of the first sub-region B11. For example, the shape of the first sub-region B11 is circular, and the different transmittances of the first sub-region B11 and the second sub-region B12 make the boundary between the first sub-region B11 and the second sub-region B12 clearer, thereby further reflecting the optimization effect of the circle on light diffraction.

[0055] like Figure 4 As shown, in one embodiment of the present application, the display panel 110 includes a first non-transparent area A2, and along the stacking direction of the display panel 110 and the controllable transmittance component 120, the first non-transparent area A2 at least partially overlaps with the second area B2. The transmittance of the controllable transmittance component 120 in the second area B2 when the display module 100 is in the first state is equal to the transmittance of the controllable transmittance component in the second area B2 when the display module 100 is in the second state.

[0056] In the embodiment of the present application, the transmittance of the controllable transmittance component 120 in the second area B2 when the display module 100 is in the first state is equal to the transmittance of the controllable transmittance component in the second area B2 when the display module 100 is in the second state, that is, the transmittance of the controllable transmittance component 120 in the second area B2 does not change with the change of the working mode of the display module 100. In the specific implementation of this embodiment, it can be achieved by not energizing the controllable transmittance component 120, thereby achieving the purpose of reducing power consumption and simplifying control difficulty.

[0057] In the implementation of the first embodiment, when the display module 100 is in working state, the transmittance of the controllable transmittance component 120 in the second area B2 is stable. The stable transmittance is relative, which means that the transmittance will not change with the conditions imposed by the outside world, but the changes in transmittance caused by oxidation, weathering or aging of the material itself belong to the category of stable transmittance recorded in this embodiment.

[0058] like Figures 8 to 11 As shown, in one embodiment of the present 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.

[0059] like Figure 8 As shown, in a 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 area B1 is a whole-surface structure. The second electrode 122 in the first area B1 is a whole-surface structure. The transmittance controllable material 123 in the first area B1 is a whole-surface structure. The whole-surface structure means that the structures in the area where it is located are continuous to form a surface.

[0060] This implementation method can realize that when the display module needs to perform transparent display, the transmittance of the controllable transmittance component 120 in the first area B1 is controlled to be increased to achieve transparent display.

[0061] like Fig. 9 As shown, in a 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 the first sub-region B11, the second sub-electrode 1212 is located in the second sub-region B12, and the first sub-electrode 1211 is electrically insulated from the second sub-electrode 1212.

[0062] In the embodiment of the present application, the transmittance of the controllable transmittance component 120 can be controlled by controlling the voltage between the first electrode 121 and the second electrode 122. The first sub-electrode 1211 is electrically insulated from the second sub-electrode 1212, and the controllable transmittance component 120 in the first sub-region B11 and the controllable transmittance component 120 in the first sub-region B12 can be independently controlled, thereby realizing independent controllability of the transmittance in the first sub-region B11 and the second sub-region B12.

[0063] like Fig. 9 As shown, in a possible implementation, the second electrode 122 is a full-surface structure.

[0064] In this implementation, the second electrode 122 is a whole-surface structure and does not need to be patterned, thereby simplifying the process, reducing the process flow, and saving costs.

[0065] like Fig.10 As shown, in a possible implementation, along the stacking direction of the display panel 110 and the controllable transmittance component 120 , the projection shape of the first electrode 121 is the same as the projection shape of the second electrode 122 and the areas are equal.

[0066] The projection of the first electrode 121 has the same shape as the projection of the second electrode 122 , so that the first sub-region B11 , the second sub-region B12 , and the second region B2 can be completely independently controlled from each other.

[0067] In this embodiment, the light transmittance controllable material 123 can be Fig. 9 or Fig.10 The entire surface structure shown can be as follows Fig.11 The patterned structure shown. Fig.11 In the embodiment, along the stacking direction of the display panel 110 and the controllable transmittance component 120, the projected shape of the first electrode 121, the projected shape of the second electrode 122, and the projected shape of the controllable transmittance material 123 are the same and have equal areas.

[0068] like Fig.12 As shown, in one embodiment of the present application, the display panel 110 also includes a first non-transparent area A2, and the transmittance controllable component 120 also includes a second area B2. Along the stacking direction of the display panel 110 and the transmittance controllable component 120, the second area B2 covers the first non-transparent area A2, and the transmittance of the transmittance controllable component 120 in the second area B2 is constant and always less than a first threshold value. The first threshold value is the transmittance critical value at which external light enters the display panel from the backlight side and causes adverse effects on the circuit inside the display panel. In a possible implementation, the first threshold value is 40%-70%, for example, the first threshold value is 50%.

[0069] In a possible implementation of this embodiment, the controllable transmittance component 120 is located on the backlight side of the display panel 110. The transmittance of the controllable transmittance component 120 in the second area B2 is constant and always less than the first threshold value, which can effectively limit the 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.

[0071] like Fig.12 As shown, in a possible implementation, the second area B2 includes a first edge B21 and a second edge B22, and the first edge B21 surrounds the second area 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 overlaps with part of the first area. The second edge B22 is composed of multiple arcs. In a possible implementation, the second edge B22 is composed of multiple arcs connected end to end in sequence.

[0072] like Figures 9 to 11 As shown, in one embodiment of the present 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 in the first region B1, the third sub-electrode 1213 is located in the second region B2, and the third sub-electrode 1213 is electrically insulated from the first sub-electrode 1211.

[0073] In the embodiment of the present application, the third sub-electrode 1213 is electrically insulated from the first sub-electrode 1211, and can realize independent control of the transmittance controllable component 120 in the second area B2 and the first area B1, so that the transmittance of the transmittance controllable component 120 in the second area B2 is not equal to the transmittance of the transmittance controllable component 120 in the first area B1.

[0074] like Fig. 9 As shown, in one embodiment of the present application, the first electrode 121 further includes: a second sub-electrode 1212.

[0075] In this embodiment, independent zoning control of the first sub-region, the second sub-region and the second region is achieved, so that each region can have its own light transmittance.

[0076] In an embodiment of the present application, the light transmittance controllable material 123 includes: at least one of an electrochromic material, a polymer network liquid crystal, or a polymer dispersed liquid crystal.

[0077] In a possible implementation, the light transmittance controllable material 123 includes: an electrochromic material or a polymer network liquid crystal or a polymer dispersed liquid crystal. Among them, the electrochromic material refers to a material that can change color under an electric field, such as changing transparency, thereby changing light transmittance. The polymer network liquid crystal or polymer dispersed liquid crystal is a liquid crystal material that can change the crystal arrangement angle under the action of voltage, thereby changing light transmittance.

[0078] In a possible implementation, the transmittance controllable material includes at least two of an electrochromic material or a polymer network liquid crystal or a polymer dispersed liquid crystal. For example, the transmittance controllable material in the first region is a polymer network liquid crystal or a polymer dispersed liquid crystal, and the transmittance controllable material in the second region is an electrochromic material. This implementation is more flexible, thereby helping to save costs.

[0079] like Fig.12 and 13 As shown, the present application also provides a display module 100 including: a display panel 110 and a controllable transmittance component 120.

The controllable transmittance component 120 is located on the backlight side of the display panel 110, and the controllable transmittance component 120 includes a first area B1 and a second area B2. Along the stacking direction of the display panel 110 and the controllable transmittance component 120, the first area B1 at least partially overlaps with the first transparent area A1, and the second area B2 covers the first non-transparent area A2.

[0080] The transmittance of the transmittance controllable component in the second area B2 is less than or equal to the transmittance of the transmittance controllable component 120 in the first area B1, and the transmittance of the transmittance controllable component 120 in the second area B2 is always less than a first threshold value, which is the transmittance critical value at which external light enters the display panel 110 from the backlight side and causes adverse effects on the circuit inside the display panel 110.

[0081] In the embodiment of the present application, the transmittance of the controllable transmittance component in the second area B2 is low and is always lower than the first threshold value, which can effectively limit the external light from entering the display panel from the backlight side, thereby preventing the pixel driving circuit of the display panel 110 from being affected by the external light and ultimately ensuring the stability of the display effect.

[0082] like Fig.12 As shown, in one embodiment of the present application, the edge shape of the second area B2 includes an arc shape. The edge shape of the second area B2 includes an arc shape, which can optimize the negative impact caused by light diffraction.

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 overlaps with part of the first area. The second edge B22 is composed of multiple arcs. In a possible implementation, the second edge B22 is composed of multiple arcs connected end to end in sequence.

[0084] like Fig.13 As shown, in a possible implementation, the shape of the second area is circular, elliptical or polygonal.

[0085] In this embodiment, the shape of the second area is circular, elliptical or polygonal, which can help to optimize the negative impact of light diffraction on the display effect.

[0086] In the embodiment of the present application, the transmittance-controllable component in the first region may be the transmittance-controllable component in the first region provided in any of the aforementioned embodiments.

[0087] In one embodiment of the present application, the transmittance of the controllable transmittance component in the first region is constant.

[0088] The transmittance of the controllable transmittance component in the first region is constant, which helps to reduce the difficulty of controlling the controllable transmittance component 120, thereby helping to reduce costs.

[0089] In a possible implementation, the light transmittance controllable component in the first area B1 includes a transparent material, which may be transparent glass. The transparent material being transparent glass can save control costs and reduce the complexity of the display module 100.

[0090] like Fig.14 As shown, an embodiment of the present application further provides a display device 200 , and the display device 200 includes the display module 100 provided by any of the aforementioned embodiments.

[0091] The display device provided in the embodiment of the present application can have a good display effect and can help reduce the adverse effects of light on the display effect.

[0092] In addition, due to its light transmittance, the pixel circuit inside the transparent display will be exposed to light for a long time. Long-term exposure to light will cause the transistor characteristics of the pixel circuit in the transparent display to drift, resulting in unstable display performance, and in severe cases, display failure.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
