Description

Technical Field

[0001] This invention relates to the field of display technology, and more specifically, to display modules and display devices. Background Technology

[0002] With the development of optical technology, display devices, including liquid crystal panels and organic light-emitting diodes, have been widely used in various fields. These display devices are particularly prevalent in vehicles such as automobiles and motorcycles, providing a more comprehensive driving assistance.

[0003] With the development of display technology, head-up displays (HUDs) that achieve dual-set displays have gradually emerged. This dual-set display refers to the virtual image floating above the hood, which includes a status projection (near projection) displaying driving information and an augmented reality projection (far projection) displaying driver assistance information, both at different projection distances. Currently, HUDs require two sets of HUD equipment to generate two sets of HUD imaging optical paths to achieve two different projection distances for the augmented reality HUD. This has disadvantages such as occupying a large amount of in-vehicle space and increasing system cost and complexity. Therefore, it is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] In view of this, the present invention provides a display module to solve the problems of existing head-up displays occupying vehicle interior space and increasing system costs.

[0006] Secondly, this application provides a display device, including a housing and the aforementioned display module; a first display panel is located inside the housing; and a second display panel is connected to the housing.

[0007] Compared with the prior art, the display module and display device provided by the present invention achieve at least the following beneficial effects:

[0023] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0024] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0026] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0028] Figure 1 This is a schematic diagram of the structure of a display module provided by the present invention; Figure 2 This is a schematic diagram of the structure of a second display panel provided by the present invention; Figure 3 This is a schematic diagram of the second display panel in a first working state in a display module provided by the present invention; Figure 4 This is a diagram showing the second display panel in a semi-open state in a display module provided by the present invention; combined with Figures 1-4As shown, this embodiment provides a display module, including: a first display panel 1 for providing first data, including a functional device 10; a second display panel 2 disposed opposite to the first display panel 1 and electrically connected to the functional device 10; a camera assembly 3 for providing second data and transmitting the second data to the functional device 10; the functional device 10 receives the first data and the second data, and processes the first data and the second data by superimposing them to obtain third data and sending it to the second display panel 2 and / or the first display panel 1 for display.

[0029] Specifically, Figure 1 As shown, the display module can be a double-sided display module, including a first display panel 1 and a second display panel 2. The first display panel 1 can be a liquid crystal display panel or an organic light-emitting display panel. Both liquid crystal display panels and organic light-emitting display panels can be existing structures. For example, when the first display panel 1 is a liquid crystal display panel, it includes a color filter substrate and an array substrate disposed opposite each other, and a liquid crystal layer located between the color filter substrate and the array substrate. When the first display panel 1 is an organic light-emitting display panel, it includes a substrate, a driving element layer, an organic light-emitting element, and a thin film encapsulation layer. The light-emitting element is disposed on the driving element layer. The light-emitting element can be any structure of an existing organic light-emitting display panel, such as an anode layer electrically connected to the driving element layer, a light-emitting layer disposed on the anode layer, and a cathode layer disposed on the organic light-emitting layer, etc., which will not be elaborated here.

[0030] The first display panel 1 provides first data, which can be real-time navigation data or other data, without specific limitations. The first display panel 1 includes functional devices 10, which can be power management modules, image processors, central processing units, flash memory, double data rate memory, system-on-a-chip, radio frequency modules, photosensitive chips, fingerprint recognition chips, iris recognition chips, face recognition chips, sensor chips, power managers, etc. In this embodiment, no specific limitations are made on functional devices 10. Functional devices 10 can be soldered onto flexible circuit boards 5, and the soldering method can adopt eutectic bonding process.

[0031] Reference Figure 1 As shown, the second display panel 2 is positioned opposite to the first display panel 1, and in combination Figure 2As shown, the second display panel 2 includes a light-emitting unit 23. The light-emitting chip 23 includes stacked light-emitting chips 230 and a driving unit 231. The light-emitting chip 230 emits light under the drive of the driving chip. Optionally, the driving unit includes a driving circuit, such as 1T1C, 7T1C, etc., where T refers to a transistor and C refers to a storage capacitor. The specific electronic components included in the driving circuit are not limited here, as long as they can provide driving current to the light-emitting chip. Optionally, the light-emitting chip is a Mini LED or Micro LED. Optionally, there can be a planarization structure between the light-emitting chip 230 and the driving unit 231, or it can be omitted. The second display panel 2 can be electrically connected to the functional device 10 via wiring, which is not specifically limited here.

[0032] The camera assembly 3 can be an existing structure, such as including a camera 31, a fixture, a color filter, a DSP (digital signal processor), a sensor, etc. The scene is captured by the camera, and the generated optical image is projected onto the sensor. Then the optical image is converted into an electrical signal, and the electrical signal is converted into digital information through analog-to-digital conversion. The digital signal is processed by the DSP and then sent to the processor for further processing, and finally converted into an image or video that can be seen on the first display panel 1. The camera assembly 3 is used to collect second data, which can be real-time video data (such as real-time video recording) or captured photos. The camera assembly 3 can be electrically connected to the functional device 10 through a line.

[0033] Functional device 10 receives first data and second data, and uses augmented reality technology to overlay the first data and second data to obtain third data. The third data can be sent only to the second display panel 2 for display, or only to the first display panel 1 for display, or both the first display panel 1 and the second display panel 2 can be sent for display. Optionally, the third data can be augmented reality information, such as an augmented reality image. Specifically, functional device 10 includes a first functional module 101 and a second functional module 102. The first functional module 101 receives the first data (such as real-time navigation data) fed back from the first display panel 1, and the second functional module 102 receives the second data (such as real-time video data) and the first data (real-time navigation data), and overlays the second data (such as real-time video data) and the first data (real-time navigation data) to obtain augmented reality information, such as an augmented reality image.

[0034] It should be noted that Augmented Reality (AR) is a technology that seamlessly integrates real-world information with virtual-world information. It can simulate and obtain corresponding virtual information, such as visual information, sound, and even taste and touch, which are difficult to experience in the real world within a certain time and space. This virtual information is then overlaid on the real world on a screen and perceived by human senses, thereby achieving a sensory experience that transcends reality.

[0035] This embodiment takes the application of the display module in the vehicle navigation scenario as an example. When the display module is applied to vehicle navigation, the first data can be real-time navigation data, such as real-time route navigation data; the second data can be real-time video data; and the third data is augmented reality information, such as augmented reality images.

[0036] When the display module is used for navigation, it can be placed in front of the driver. The first display panel 1 can display real-time navigation data, and the camera component 3 can collect real-time video data (such as capturing real-world scenes) and transmit the real-time video data to the functional device 10. The functional device 10 receives the real-time navigation data and the real-time video data, and uses augmented reality technology to overlay the first and second data. Specifically, according to a preset algorithm, the first and second data are overlaid to obtain the overlaid augmented reality information, such as an augmented reality image. The overlaid augmented reality information is then directly displayed on the second display panel 2, so that the first display panel 1 can directly display real-time navigation data, WeChat messages, QQ messages, SMS messages, phone calls, etc., while the second display panel 2 only displays the augmented reality information, which is beneficial for the driver to see more clearly. To better observe road conditions, specifically, the first display panel 1 can display real-time route navigation information, while the second display panel 2 can display real-time directional instructions for the car in conjunction with actual road conditions, such as the relative distance and speed of vehicles ahead, whether there are intersections ahead, and how the car should proceed (e.g., straight, left turn, or right turn). Using the above solution, the driver can not only see real-time route navigation information using the first display panel 1, but also other information, such as WeChat messages (simple text, video, and voice), SMS messages, and system recommendations. The second display panel 2 can display augmented reality images. In other words, this solution can realize mobile augmented reality display function, thereby enhancing the driver's perception of the actual driving environment. Moreover, there is no need to install a head-up display in the car, thus avoiding the occupation of interior space and reducing costs.

[0037] Of course, depending on the actual situation, augmented reality information can also be displayed on the first display panel 1, or part of the augmented reality information can be displayed on the first display panel 1 and another part can be displayed on the second display panel 2. As long as the augmented reality display function can be achieved, this embodiment does not make specific limitations.

[0038] It should be noted that the above algorithm can be an image feature detection and matching algorithm. In practical applications, after feature matching, it is necessary to use the Random Sampling Consensus (RANSAC) algorithm to remove erroneous matching points and eliminate invalid data in the matching points. Of course, this algorithm can also be set according to the needs of the actual application, and no specific limitation is made here.

[0039] Of course, depending on the actual situation, the above solution can also be applied to other application scenarios, such as education scenarios. The first data can be data displayed by a certain learning software, and the second data can be images or videos captured by a camera component. The functional device receives the data displayed by the learning software and the images or videos, and uses augmented reality technology to overlay the above two information. The overlaid data is then directly displayed on the first display panel 1 and / or the second display panel 2, which helps to increase the display effect of the display module and enhance the user experience.

[0040] Compared with the prior art, the display module provided in this embodiment achieves at least the following beneficial effects:

[0041] The display module provided in this embodiment includes: a first display panel 1 for providing first data, including a functional device 10; a second display panel 2 disposed opposite to the first display panel 1 and electrically connected to the functional device 10; and a camera assembly 3 for providing second data and transmitting the second data to the functional device 10. The functional device 10 receives the first data and the second data, and processes the first data and the second data by superimposing them to obtain third data, which is then sent to the second display panel 2 and / or the first display panel 1 for display. By adopting the above scheme, through the mutual cooperation between the first display panel 1, the second display panel 2, and the camera assembly 3, augmented reality information is displayed on the first display panel 1 and / or the second display panel 2 without occupying other space (such as indoor or vehicle interior). The display module directly realizes the mobile augmented reality display function, which can improve the user experience and is easy to carry.

[0042] In one alternative embodiment, the second display panel 2 includes a first working state; in the first working state, the second display panel 2 and the first display panel 1 do not overlap at least partially along a first direction X, where the first direction X is the direction from the first display panel 1 to the second display panel 2.

[0043] Specifically, continue to refer to Figure 3As shown, the second display panel 2 includes a first working state, which can be an unfolded state. In the unfolded state, along the first direction X, the second display panel 2 does not overlap with the first display panel 1. When the second display panel 2 displays augmented reality information, it avoids the partial obstruction of this information, which is beneficial for the user to view the augmented reality image. Of course, depending on the actual situation, in the unfolded state, the second display panel 2 and the first display panel 1 may only partially overlap, while the majority of their overlap remains non-overlapping. This minimizes the obstruction of the augmented reality information displayed on the second display panel 2, which also benefits the user's viewing experience.

[0044] In one optional embodiment, the second display panel 2 further includes a second working state, in which the second display panel 2 overlaps with the first display panel 1 along the first direction X, the first direction X being the direction from the first display panel 1 to the second display panel 2.

[0045] Specifically, continue to refer to Figure 1 As shown, the second display panel 2 also includes a second working state, which can be the unexpanded state of the second display panel 2. In the unexpanded state of the second display panel 2, along the first direction X, the second display panel 2 overlaps with the first display panel 1, which can be understood as the second display panel 2 covering the first display panel 1. In the unexpanded state of the second display panel 2, the second display panel 2 can display other graphics to achieve a similar beautification and decoration effect as on a mobile phone case.

[0046] It should be noted that: Figure 4 The second display panel 2 is in a semi-open state between the first and second working states. When the display device includes a housing 6, the second display panel 2 and the housing 6 can rotate. When the second display panel 2 rotates above the first display panel 1, the display surfaces of the first display panel 1 and the second display panel 2 are on the same side after opening. Figure 3 As shown; when the second display panel 2 is in the unfolded state, it can achieve double-sided display, as shown. Figure 1 As shown; of course, depending on the actual situation, the second display panel 2 and the housing 6 can also be in other ways, such as the second display panel 2 and the housing 6 can be in a sliding manner, which can also realize double-sided display. This embodiment does not limit this.

[0047] In one alternative embodiment, Figure 5 This is a schematic diagram of the structure of another display module provided by the present invention; Figure 6 This is a schematic diagram of the second display panel in a first working state in another display module provided by the present invention; see also Figure 2 , Figure 5 and Figure 6 As shown, this embodiment includes: a second display panel 2, including multiple pixel areas 21 and transparent areas 22; and a light valve 4, located between the first display panel 1 and the second display panel 2, including a third working state and a fourth working state. In the third working state, the light valve 4 has a first transmittance; in the fourth working state, the light valve 4 has a second transmittance; the first transmittance is less than the second transmittance.

[0048] Specifically, in combination Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, the second display panel 2 includes multiple pixel areas 21 and transparent areas 22; the transparent area 22 is between two adjacent pixel areas 21, which can be understood as the second display panel 2 being a transparent screen; the light valve 4 is located between the first display panel 1 and the second display panel 2, and includes a third working state and a fourth working state. The third working state can be a closed state, and the fourth working state can be an open state. When the light valve 4 is in the closed state, the light valve 4 has a first transmittance; when the light valve 4 is in the open state, the light valve 4 has a second transmittance. The first transmittance is less than the second transmittance. The difference between the first and second transmittance is used to control the transparency of the second display panel 2. Of course, depending on the actual situation, the third and fourth working states can also be two different states, with different open states, which can also achieve a difference between the first and second transmittance, thereby controlling the transparency of the second display panel 2.

[0049] It should be noted that the driving unit 231 can be transparent or semi-transparent. Even if the driving unit is semi-transparent, only the positions of the electronic components are not transparent, while the gaps between the electronic components are still transparent, thereby reducing the obstruction of the upper light-emitting chip.

[0050] Optionally, continue to refer to Figure 5 As shown, when the second display panel 2 is in an unfolded state and the light valve 4 is in a closed state, if the first transmittance is a low transmittance (e.g., less than 20%), the second display panel 2 becomes a non-transparent screen. This can be understood as the second display panel 2 being a normal display screen. If the display device includes a housing 6 with a decorative pattern printed on its back, when the second display panel 2 is in an unfolded state and the light valve 4 is in an open state, if the second transmittance is a high transmittance (e.g., greater than 70%), the decorative pattern on the back of the housing 6 is superimposed on the image displayed on the second display panel 2. The superimposed image further enhances the display effect of the display module.

[0051] Optionally, continue to refer to Figure 5 and Figure 6As shown, the light valve 4 is a liquid crystal film, which includes liquid crystal molecules. By controlling the degree of deflection of the liquid crystal molecules, the transparency of the second display panel 2 is controlled. Specifically, the liquid crystal film includes liquid crystal molecules and an electrode layer. The liquid crystal molecules are deflected under the control of the electrode layer to control the transparency of the second display panel 2. The transparency of the second display panel 2 is achieved through the liquid crystal film. It should be noted that the liquid crystal film only has a transparency control function and does not have a display function.

[0052] In one alternative embodiment, Figure 7 This is a schematic diagram of another display module provided by the present invention; Figure 8 This is a schematic diagram of the second display panel in a first working state in another display module provided by the present invention; combined with Figure 7 and Figure 8 As shown, the camera assembly 3 includes a camera 31; the light valve 4 has an opening 41, and the orthographic projection of the camera 31 on the plane of the first display panel 1 and the orthographic projection of the opening 41 on the plane of the first display panel 1 at least partially overlap.

[0053] Specifically, in combination Figure 7 and Figure 8 As shown, the camera assembly 3 includes a camera 31, which can collect second data, which can be image or video data. An opening 41 is provided on the light valve 4, which passes through the light valve 4 in the first direction X. The orthographic projection of the camera 31 on the plane of the first display panel 1 overlaps with the orthographic projection of the opening 41 on the plane of the first display panel 1, thus avoiding obstruction of the camera 31 and facilitating the camera 31's acquisition of the second data. Optionally, the orthographic projection of the camera 31 on the plane of the first display panel 1 is located within the orthographic projection of the opening 41 on the plane of the first display panel 1, which is even more beneficial for the camera 31 to acquire the second data. Of course, depending on the actual situation, the orthographic projection of the camera 31 on the plane of the first display panel 1 and the orthographic projection of the opening 41 on the plane of the first display panel 1 only partially overlap to minimize obstruction of the camera 31 and thus minimize the impact on the camera 31's acquisition of the second data.

[0054] In one alternative embodiment, continue to refer to Figure 1 As shown, the resolution of the first display panel 1 is higher than that of the second display panel 2. Resolution refers to the number of pixels displayed per unit area. By reducing the resolution of the second display panel 2, the transparency of the second display panel 2 is increased.

[0055] Optionally, continue to refer to Figure 1As shown, the pixel density of the first display panel 1 is higher than that of the second display panel 2. Pixel density represents the number of pixels per inch. By reducing the pixel density of the second display panel 2, the transparency of the second display panel 2 is increased. For example, the pixel density of the first display panel 1 can be between 300 PPI and 450 PPI, and the pixel density of the second display panel 2 can be between 100 PPI and 200 PPI.

[0056] In one alternative embodiment, continue to refer to Figure 1 As shown, the thickness of the second display panel 2 is not less than the thickness of the first display panel 1. When the display module is fixed on the housing 6, the fact that the thickness of the second display panel 2 is not less than the thickness of the first display panel 1 helps to increase the mechanical properties between the second display panel 2 and the housing 6.

[0057] In one alternative embodiment, continue to refer to Figure 1 As shown, the second display panel 2 is any one of a Micro LED display, a Mini LED display, or an OLED display.

[0058] Specifically, the second display panel 2 can be a Micro LED (micro-light-emitting diode) display. Micro LED mainly refers to miniaturized LEDs and matrix technology. Simply put, it involves thinning, miniaturizing, and arraying LED backlights, which can make Micro LEDs smaller than 100μm and achieve self-illumination like OLEDs (organic light-emitting semiconductors).

[0059] The second display panel 2 can also be a Mini LED (sub-millimeter light-emitting diode) display. The size of the LED is less than 200μm. Since Mini LED is smaller than traditional LED, it can achieve more precise control of the light source of the LCD panel. Combined with more precise local dimming technology, it has higher contrast.

[0060] The second display panel 2 can also be an OLED display. OLED is a current-driven organic light-emitting device that emits light through the injection and recombination of charge carriers. The luminous intensity is proportional to the injected current. Under the influence of an electric field, holes generated at the anode and electrons generated at the cathode move and are injected into the hole transport layer and electron transport layer, respectively, migrating to the light-emitting layer. When the two meet in the light-emitting layer, they generate energy excitons, which excite the light-emitting molecules to ultimately produce visible light.

[0061] It should be noted that the second display panel 2 can also be an LED display. Since Micro LED displays have advantages over LED displays and OLED displays such as high brightness, wide color gamut, long lifespan and fast response, when this display module is applied to automotive applications, Micro LED displays have a unique advantage in transparency compared to LED displays, Mini LED displays and OLED displays because Micro LEDs are less than 100μm and do not require a polarizing film encapsulation structure.

[0062] Based on the same inventive principle, the present invention also provides a display device 100. Figure 9 This is a structural schematic diagram of a display device 100 provided by the present invention, combined with... Figure 1 and Figure 9 As shown, the display device 100 includes a housing 6 and any of the display modules provided by the present invention. The display module includes a first display panel 1 and a second display panel 2, wherein the first display panel 1 is located inside the housing 6; the second display panel 2 is connected to the housing 6. Specifically, the connection between the second display panel 2 and the housing 6 can be a hinge or a sliding connection. The light-emitting surface of the second display panel 2 can be designed according to the connection method between the second display panel 2 and the housing 6, but this embodiment does not specifically limit this.

[0063] The display device 100 provided in this embodiment of the invention can be any electronic product with display function, including but not limited to the following categories: television, laptop, desktop monitor, tablet computer, digital camera, mobile phone, smart bracelet, smart glasses, vehicle display, medical equipment, industrial control equipment, touch interactive terminal, etc.

[0064] In one alternative embodiment, Figure 10 This is a schematic diagram of a second display panel in a first working state in a display device provided by the present invention; Figure 11 This is a schematic diagram of the second display panel in a first working state in another display device provided by the present invention; see reference. Figure 10 and Figure 11 As shown, the first display panel 1 and the second display panel 2 are located on opposite sides of the housing 6.

[0065] Specifically, in combination Figure 1 and Figure 3As shown, the first display panel 1 and the second display panel 2 are positioned opposite each other on the housing 6. When the second display panel 2 is in its unfolded state, it can be located on the side of the housing 6 away from the first display panel 1, such as on the back side of the first display panel 1. Of course, depending on the actual situation, the second display panel 2 can also be located in front of the first display panel 1; when the second display panel 2 is unfolded, it is located above the first display panel 1; or, depending on the actual situation, the second display panel 2 in its unfolded state is not limited to being above the first display panel 1, but can also be in other positions, such as being to the left of the first display panel 1. Figure 10 As shown, or, alternatively, the second display panel 2 can be located to the right of the first display panel 1, as shown. Figure 11 As shown.

[0066] Optionally, combined Figure 5 and Figure 6 As shown, when the display module also includes a light valve 4, the light valve 4 is located on the side of the housing 6 near the second display panel 2. When the second display panel 2 is in the unfolded state, the light valve 4 is located between the housing 6 and the second display panel 2. The second display panel 2 is a transparent screen. The transparency of the second display panel 2 is controlled by the light valve 4. When the housing 6 is designed with an aesthetic pattern on the side near the light valve 4, when the light valve 4 is in the open state, the aesthetic pattern on the housing 6 is superimposed on the image displayed on the second display panel 2 to achieve a better display effect. When the light valve 4 is in the closed state, the second display panel 2 can be displayed as a non-transparent screen.

[0067] As can be seen from the above embodiments, the display module and display device provided by the present invention achieve at least the following beneficial effects:

[0068] The present invention provides a display module and a display device. The display module includes: a first display panel for providing first data, including functional components; a second display panel disposed opposite to the first display panel and electrically connected to the functional components; a camera assembly for providing second data and transmitting the second data to the functional components; the functional components receive the first data and the second data, and superimpose the first data and the second data to obtain third data, which is then sent to the second display panel and / or the first display panel for display. By employing the above scheme, through the mutual cooperation between the first display panel, the second display panel, and the camera assembly, augmented reality information is displayed on the first display panel and / or the second display panel without occupying other space (such as indoor or vehicle interior). The mobile augmented reality display function is directly realized through the display module, which can improve the user experience.

[0069] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention.
