Technical Field

[0001] This application relates to the field of vehicle technology, specifically to an in-vehicle transparent display screen and a modulation method. Background Technology

[0002] With the rapid development of the automotive industry, intelligent vehicle use has become a trend, and screenless or minimally screened vehicles are becoming the development trend for high-end cars. In order to provide a more spacious cabin while integrating and realizing the multi-functional and multi-directional display needs of intelligent vehicles, automakers have begun to explore the application of transparent displays in intelligent vehicles.

[0003] Transparent displays allow users to see not only the information displayed on the screen but also information behind it, providing a better viewing experience. Most existing displays are LCD screens, which are relatively small and often installed near the dashboard. When drivers view information on LCD screens, their eyes are temporarily off the road, potentially posing a safety hazard. Furthermore, existing transparent displays are susceptible to issues like light distortion due to ambient light, resulting in poor display quality and a less than ideal user experience.

[0027] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0029] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0030] First, it's important to clarify that a glass substrate is a thin sheet of glass with an extremely smooth surface, and it's one of the key basic materials in the flat panel display industry. A glass film is a thin sheet of glass with a thickness ranging from a few micrometers to several hundred micrometers, and it can be used as a capacitor material and a microscope cover plate.

[0031] Electrochromic glass, also known as electrochromic dimming glass, operates on two principles: First, it uses voltage to alter the arrangement of liquid crystal molecules for dimming. A thin liquid crystal film is sandwiched between two pieces of glass. When an electric current is applied, the excellent rearrangement of the liquid crystal crystals allows for adjustment of the light transmittance according to the intensity of incident light, meeting lighting requirements. The basic structure of liquid crystal dimming glass consists of micron-sized liquid crystal cells dispersed within the glass matrix, sandwiched between transparent conductive films, forming a special sandwich structure. When no external voltage is applied, the liquid crystal molecules are randomly arranged, causing strong scattering of light and thus eliminating transparency. When a voltage is applied between the two transparent conductive films, the liquid crystal molecules align with the glass surface, allowing light to pass through directly and revealing transparency. Second, it uses changes in the electric field to alter transmittance. Glass based on this principle consists of a base glass and an electrochromic system. By utilizing the adjustable light transmittance of the electrochromic material under an electric field, the purpose of adjusting transparency can be achieved. Meanwhile, electrochromic systems can reduce the significant energy consumption of office buildings and residential homes in keeping them cool in summer and warm in winter by selectively absorbing or reflecting external heat radiation and preventing internal heat diffusion. Simply put, electrochromism is caused by electrochemical redox reactions occurring within the electrochromic material.

[0032] LED (light-emitting diode) is a commonly used light-emitting device that releases light through the recombination of electrons and holes. It has wide applications in the lighting field. LEDs can efficiently convert electrical energy into light energy and have a wide range of uses in modern society, such as lighting, flat panel displays, and medical devices.

[0033] LCD (Liquid Crystal Display) is a flat, ultra-thin display device composed of a number of color or monochrome pixels placed in front of a light source or reflector. LCDs consume very little power, making them popular with engineers and suitable for battery-powered electronic devices. Their main principle is to use electric current to stimulate liquid crystal molecules to create dots, lines, and surfaces, which, in conjunction with a backlight, form an image.

[0034] OLED (Organic Light-Emitting Diode), also known as organic electroluminescence display or organic electroluminescence semiconductor, is a current-driven organic light-emitting device. It emits light through the injection and recombination of charge carriers, with the luminous intensity directly proportional to the injected current. Under the influence of an electric field, holes generated at the anode and electrons at the cathode migrate and are injected into the hole transport layer and electron transport layer, respectively, before migrating to the emissive layer. When these two electrons meet in the emissive layer, they generate excitons, which excite the light-emitting molecules, ultimately producing visible light.

[0035] Mini LED (Mini Light Emitting Diode Display) is a type of LED technology. Mini LED technology is primarily used in multi-zone backlit displays and large RGB fine-pitch displays. The multi-zone backlight control function in Mini LED technology allows for local dimming, enhancing the contrast and resolution of the image to achieve HDR effects, similar to OLED displays. Another technology uses Mini LED chips to create large-size screens with a pixel pitch of less than 1.0 mm. Besides improving the resolution of LED displays, this also creates new mainstream display specifications. A Mini-LED device is an LED device with a chip long side dimension between 100 and 300 μm. It consists of a Mini LED pixel array and driving circuitry, with a pixel center-to-center spacing of 0.3-1.5 mm.

[0036] Micro LED (Micro Light Emitting Diode Display) is a display technology that utilizes the miniaturization and arraying of LED structures to achieve dimensions of only 1-10 μm. These μLEDs are then mass-produced and transferred onto a circuit substrate (including the lower electrode and transistors). The substrate can be rigid, flexible, transparent, or opaque. A protective layer and upper electrode are then applied using physical deposition, followed by encapsulation of the upper substrate to complete a simple Micro LED display. A typical μLED structure is a PN junction diode composed of a direct bandgap semiconductor material. Micro LED is a next-generation display technology that miniaturizes and arrays LED backlights, focusing on individually driving inorganic self-emissive light and extending product lifespan.

[0037] RGB three-color display mode, also known as RGB color mode (red, green, blue color mode), is an industry color standard. It obtains a variety of colors by changing the three color channels of red, green, and blue and superimposing them. RGB represents the colors of the three channels of red, green, and blue. This standard includes almost all colors that human vision can perceive and is one of the most widely used color systems.

[0038] Figure 1 This is a schematic diagram illustrating the implementation environment of an in-vehicle transparent display modulation method, as shown in an exemplary embodiment of this application.

[0039] Reference Figure 1 As shown, the system architecture may include a data acquisition device 101 and a computer device 102. The computer device 102 may be at least one of a desktop graphics processing unit (GPU) computer, a GPU computing cluster, or a neural network computer. Those skilled in the art can use the data acquisition device 101 to acquire the driving mode of the vehicle to be modulated, weather information, and the user's display requirements; they can also use the computer device 102 to determine the driving scenario based on the weather information and driving mode; and control the in-vehicle transparent display screen to execute a corresponding preset modulation scheme according to the user's display requirements and driving scenario, thereby modulating the transparency and contrast of the in-vehicle transparent display screen. Therefore, the technical solution of this application embodiment can improve the user's visual experience by modulating the transparency of each area to adjust the transparency and contrast of the in-vehicle transparent display screen.

[0040] As an illustration, the vehicle-mounted transparent display screen is set on the windshield of the vehicle to be modified. It should be noted that the vehicle-mounted transparent display screen is not limited to the windshield of the vehicle to be modified, but can also be set on other windows of the vehicle to be modified, such as the rear windshield.

[0041] It should be noted that the vehicle-mounted transparent display modulation method provided in this application embodiment is generally executed by computer device 102, and correspondingly, the vehicle-mounted transparent display modulation device is generally disposed in computer device 102.

[0042] In one embodiment of this application, the vehicle-mounted transparent display screen includes a substrate, a transparent modulation unit, and a transparent display unit. The substrate, the transparent modulation unit, and the transparent display unit are stacked sequentially from the outside of the vehicle to the inside of the vehicle to form the vehicle-mounted transparent display screen. The transparent display unit is used to display information to be displayed. The transparent modulation unit is used as a background for displaying the information to be displayed. The transparent modulation unit includes multiple first modulation units and multiple second modulation units. A first modulation unit is used to control the transparency of a first modulation area corresponding to at least one first modulation unit according to the user's display needs and driving scenario. A second modulation unit is used to control the transparency of a second modulation area corresponding to at least one second modulation unit according to the user's display needs and driving scenario. By modulating the transparency of the first modulation area and the second modulation area, the contrast of the vehicle-mounted transparent display screen is adjusted. Customized design and control according to the user's display needs and driving scenario, and controlling the transparency of each area separately, improves the display performance of the vehicle-mounted transparent display screen and enhances the user's visual experience and user experience.

[0043] In this embodiment, Figure 2 This is a schematic diagram illustrating the structure of a vehicle-mounted transparent display screen, as shown in an exemplary embodiment of this application. Figure 2 As shown, the vehicle-mounted transparent display screen of this application includes a substrate 10, a transparent modulation unit 20, and a transparent display unit 30. The stacking structure of the substrate 10, the transparent modulation unit 20, and the transparent display unit 30 is oriented from the outside of the vehicle to the inside; that is, one side of the substrate 10 is the transparent modulation unit 20, and the other side is the outside of the vehicle; one side of the transparent display unit 30 is the transparent modulation unit 20, and the other side is the light-emitting side of the transparent display, corresponding to the driver's cabin. In this application, the substrate 10 is made of a light-transmitting material, which can be at least one of a transparent glass substrate and a transparent glass film; the transparent modulation unit 20 can be a patterned electroluminescent structure layer, i.e., a pixel-based electrochromic structure layer; the transparent display unit 30 can be a display screen such as an LED transparent screen, an LCD transparent screen, an OLED transparent screen, a Mini LED transparent screen, and a Micro LED transparent screen, preferably an OLED, Mini LED, or Micro LED display mode.

[0044] In one embodiment of this application, the transparent display unit includes multiple non-transparent display areas and multiple transparent display areas, wherein each non-transparent display area is disposed at a display pixel opening position of the transparent display unit for displaying at least part of the information to be displayed; the multiple transparent display areas are made of transparent material.

[0045] In this embodiment, the transparent display unit of the vehicle-mounted transparent display screen is the same as that of common display devices. The transparent display unit includes a driving circuit and a light-emitting unit. The driving circuit is used to control and drive the vehicle-mounted transparent display screen, and the light-emitting unit is used to emit light. The transparent display unit can be used as an independent display structure to display images. Figure 3 This is a schematic diagram illustrating the structure of a transparent display unit in an in-vehicle transparent display screen, as shown in an exemplary embodiment of this application. Figure 3 As shown, the transparent display unit 30 of this application includes a non-transparent display area 310 and a transparent display area 320. The non-transparent display area is also the display area, and the transparent display area is also the non-display area. The non-transparent display area 310 corresponds to the display pixel opening position of the transparent display unit and can correspond to the sub-pixel unit of the display, i.e., the transparent display unit. The transparent display area is made of transparent material, and at least one of the modulation result of the transparent modulation unit and external vehicle information can be displayed through the transparent display area.

[0046] In one embodiment of this application, at least one first modulation unit corresponds to a first control driver, and the first control driver is used to control the transparency and contrast of at least one first modulation region; at least one second modulation unit corresponds to a second control driver, and the second control driver is used to control the transparency and contrast of at least one second modulation region.

[0047] In this embodiment, at least one first modulation unit has a first control driver, and at least one second modulation unit has a second control driver. This means that different voltages and currents can be used to control the transparency of the two regions, achieving different levels of transparency. Specifically, each first modulation unit can correspond to one first control driver, and each second control unit can correspond to one second control driver; or multiple first modulation units can correspond to one first control driver, and multiple second control units can correspond to one second control driver. One first control driver can control the transparency of the first modulation region corresponding to one, multiple, or even all of the first modulation units, and one second control driver can control the transparency of the second modulation region corresponding to one, multiple, or even all of the second modulation units. By modulating the transparency of the first and second modulation regions, the contrast of the vehicle-mounted transparent display screen is adjusted.

[0048] In one embodiment of this application, a first modulation region includes a central display region and a side edge display region. The position of the central display region corresponds to the position of a non-transparent display region. The display period of the central display region is the same as the display period of the non-transparent display region. The size of the central display region is equal to the size of the non-transparent display region. The region obtained by combining the side edge display region and a second modulation region corresponds to a transparent display region. The size of the first modulation region is greater than or equal to the size of the non-transparent display region.

[0049] Figure 4 This is a schematic diagram illustrating the structure of a transparent modulation unit for an in-vehicle transparent display screen, as shown in an exemplary embodiment of this application. In this embodiment, the transparent modulation unit includes multiple first modulation units 210 and multiple second modulation units 220. The first modulation units 210 correspond to a central display area 2110 and an edge display area 2120. The position of the central display area 2110 corresponds to the position of the display area 310 of the transparent display unit. The display period of the central display area 2110 is consistent with the display period of the display area 310 of the transparent display unit. The area size of the central display area 2110 is consistent with the area size of the display area 310 of the transparent display unit. The area formed by combining the edge display area 2120 and the corresponding areas of the second modulation units 220 corresponds to the non-display area, i.e., the transparent display area 320. That is, the area corresponding to the first modulation unit 210 corresponds one-to-one with the display area, i.e., the non-transparent display area 310. The size of the area corresponding to the first modulation unit 210 is greater than or equal to the size of the non-transparent display area 310 to ensure the display effect of the display pixel edges. It should be noted that the first modulation unit 210 has a first control drive, and the second modulation unit 220 has a second control drive. That is, different voltages and currents can be used to control the two regions to achieve different levels of transparency.

[0050] In one embodiment of this application, the transparent display unit includes multiple non-transparent display areas, each non-transparent display area having multiple display pixels. One display pixel is located inside a first modulation unit. The multiple display pixels include multiple first display pixels, multiple second display pixels, and multiple third display pixels. The multiple first display pixels are used to emit light to display a first color, and the position of one first display pixel corresponds to the position of one first modulation unit. The multiple second display pixels are used to emit light to display a second color, and the position of one second display pixel corresponds to the position of one first modulation unit. The multiple third display pixels are used to emit light to display a third color, and the position of one third display pixel corresponds to the position of one first modulation unit. The first color, the second color, and the third color are mixed to display a fourth color.

[0051] In this embodiment, as Figure 5 As shown, Figure 5This is a schematic diagram illustrating the structure of a vehicle-mounted transparent display screen, as shown in another exemplary embodiment of this application. The transparent display screen and display device include a substrate 10, a transparent modulation unit 20, and a transparent display unit 30. The transparent display unit 30 has a first display pixel 3110, which can emit light to display a single color, such as red; a second display pixel 3120, which can emit light to display a single color, such as green; and a third display pixel 3130, which can emit light to display a single color, such as blue. The first, second, and third display pixels can be mixed to form white light. It should be noted that this application is not limited to the RGB three-color display mode; RGBW (RGBW refers to adding a white sub-pixel to the RGB three-primary-color pixels to form RGBW four-color pixels), RGBY (RGBY refers to adding a yellow sub-pixel to the RGB three-primary-color pixels to form RGBY four-color pixels, which can make color representation more accurate), and other color display methods can be used by analogy, and will not be described in detail here. The transparent modulation unit 20 includes a first modulation unit 210 and a second modulation unit 220. The first modulation units 210 are positioned one-to-one with the first display pixel 3110, the second display pixel 3120, and the third display pixel 3130, and the size of the area corresponding to the first modulation unit 210 is not smaller than the size of the display pixel, that is, the size of the first modulation area is greater than or equal to the size of the non-transparent display area. In this embodiment, the modulation units 210 below the first display pixel 3110, the second display pixel 3120, and the third display pixel 3130 can independently control the transparency of their corresponding areas, or they can control the transparency of their corresponding areas one-to-one. That is, multiple first modulation units can independently control the transparency of the area corresponding to each first modulation unit, or they can simultaneously control the transparency of the area corresponding to each first modulation unit.

[0052] In one embodiment of this application, the driving scenario includes a driving mode and weather information. If the driving mode is a non-driving state and the user's display requirement is leisure and entertainment, the transparency of multiple first modulation areas and multiple second modulation areas is controlled to be less than or equal to a first preset transparency. If the driving mode is a driving state and the weather information is sunny, the transparency of multiple first modulation areas is controlled to be less than or equal to the first preset transparency, and the transparency of multiple second modulation areas is controlled to be less than or equal to the second preset transparency. If the driving mode is a driving state and the weather information is cloudy and rainy, the transparency of multiple first modulation areas is controlled to be less than or equal to the first preset transparency, and the transparency of multiple second modulation areas is controlled to be less than or equal to a third preset transparency. The first preset transparency is less than the second preset transparency, and the second preset transparency is less than the third preset transparency.

[0053] In this embodiment, in order to apply the in-vehicle transparent display screen to real-world vehicle application scenarios, the modulation scheme can be divided into several types according to the user's display needs and driving scenarios. Table 1 shows illustrative modulation schemes for different driving scenarios and different users' display needs. The relevant modulation schemes are shown in Table 1:

[0054] Table 1

[0055] 1 Non-driving state - leisure and entertainment 210 has low transmittance, 220 has low transmittance 2 Driving Status - Sunny 210 has low transmittance, while 220 has average transmittance. 3 Driving conditions - Rainy day 210 has low transmittance, while 220 has high transmittance.

[0056] As shown in Table 1, in Scenario 1, when the vehicle is in a non-driving state (i.e., the driving mode in the driving scenario is non-driving) and the user's display requirement is leisure and entertainment, the transparent modulation units 210 and 220 can be modulated to low transmittance. That is, the first modulation unit 210 is modulated to low transmittance and the second modulation unit 220 is modulated to low transmittance. In other words, the transparency of multiple first modulation areas and the transparency of multiple second modulation areas are controlled to be less than or equal to the first preset transparency. In this scenario, the transparency requirement is not high. By controlling the background to low transparency, a high-contrast display can be obtained, improving the user experience. Scenario 2: When the vehicle is in driving mode and the weather is sunny (i.e., the driving mode in the driving scenario is non-driving mode and the weather information outside the vehicle is sunny), the first modulation unit 210 can be modulated to low transmittance, and the second modulation unit 220 can be modulated to normal transmittance. In this scenario, modulating the first modulation unit 210 to low transmittance can achieve higher contrast and reduce the interference of external light. At the same time, modulating the transmittance of the second modulation unit 220 to normal state means controlling the transparency of multiple first modulation areas to be less than or equal to the first preset transparency, and controlling the transparency of multiple second modulation areas to be less than or equal to the second preset transparency. This provides a better viewing effect for users while ensuring that they can see the outside scenery, i.e., the information outside the vehicle, and protects their eyes from sunlight stimulation, while still allowing them to clearly see the information to be displayed. Scenario 3: When the vehicle is in driving mode and the outside weather is cloudy or rainy (i.e., the driving mode in the driving scenario is non-driving mode), and the weather outside the vehicle is sunny, the first modulation unit 210 can be modulated to low transmittance, and the second modulation unit 220 can be modulated to high transmittance. This means controlling the transparency of multiple first modulation areas to be less than or equal to a first preset transparency, and controlling the transparency of multiple second modulation areas to be less than or equal to a third preset transparency. This achieves clear display of information outside the vehicle while also clearly displaying the information to be displayed, improving the user experience. It should be noted that Table 1 in this embodiment is only an example. Depending on the user's display needs, this in-vehicle transparent display screen can be designed with multiple transparent modulation units to adapt to different user scenario requirements, which will not be elaborated upon here.

[0057] The vehicle-mounted transparent display screen of this application can utilize the modulation of the background transparency of the non-transparent display area and the transparent display area of ​​the transparent display unit, that is, the modulation of the transparency of the first modulation area and the second modulation area, to achieve customized design according to the user's display needs and driving scenarios. It is not affected by external light, accurately controls the transparency and contrast of the vehicle-mounted transparent display screen, improves the display performance of the vehicle-mounted transparent display screen, creates a high-contrast vehicle-mounted transparent display screen, and enhances the user's visual experience.

[0058] Figure 6 This is a schematic flowchart illustrating an exemplary embodiment of a vehicle-mounted transparent display modulation method according to this application.
