Technical Field

[0001] This invention relates to the field of graphics display, and more specifically to a programmable integrated display device and a user interaction method using the device. Background Technology

[0002] In recent years, some car models have supported displaying personalized content, such as patterns or text, on the vehicle body, a feature that has been welcomed by many users. Currently, this function is mainly achieved through the vehicle's matrix LED taillights. However, this method has many limitations and shortcomings, such as a single color (usually only red is supported), limited display position and size (depending on the size of the taillights), and the need for continuous power supply to maintain the display, leading to increased energy consumption, etc.

[0003] Therefore, there is an urgent need for a display device that further improves upon existing technologies. Summary of the Invention

[0005] To address the problems in existing technologies, this invention proposes a programmable integrated display device and a user interaction method using the device. The integrated display device may include a cholesteric LCD and a backlight panel. The cholesteric LCD can be configured to display specific content by reflecting ambient light during the day (i.e., when ambient light intensity is above a threshold) and to display that content at night (i.e., when ambient light intensity is below the threshold) via the backlight panel. The integrated display device can be programmed and interacted with by a user.

[0006] In other words, the present invention employs an integrated display device comprising a cholesteric LCD and a backlight panel.

[0023] In one embodiment of the invention, the in-vehicle integrated display device may be further configured to display the graphic when a user is detected approaching via an in-vehicle proximity sensor, and the ambient light brightness is determined by an in-vehicle ambient light sensor.

[0024] In one embodiment of the present invention, the backlight panel may be a MiniLED.

[0025] In another embodiment of the present invention, a method for interacting with a user using the in-vehicle integrated display device described in the above embodiments is disclosed, the method comprising:

[0026] Sensing the proximity of the user to the in-vehicle integrated display device;

[0027] When a user is detected approaching the in-vehicle integrated display device, the device displays programmed graphics, including displaying the graphics via reflection of ambient light from the cholesteric LCD panel included in the device when the ambient light is above a threshold, and displaying the graphics via illumination provided to the cholesteric LCD panel by a backlight panel included in the device when the ambient light is below the threshold; and

[0042] The various embodiments will now be described in more detail with reference to the accompanying drawings, which form part of this invention and illustrate specific exemplary embodiments. However, the embodiments may be implemented in many different forms and should not be construed as limiting the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of these embodiments to those skilled in the art. The embodiments may be implemented as methods, systems, or devices. Therefore, these embodiments may be implemented in hardware, entirely in software, or in a combination of software and hardware aspects. Therefore, the following detailed description is not intended to be limiting.

[0043] The steps in each flowchart can be performed by hardware (e.g., processor, engine, memory, circuitry), software (e.g., operating system, application, driver, machine / processor executable instructions), or a combination thereof. As will be understood by those skilled in the art, the methods involved in each embodiment may include more or fewer steps than shown.

[0044] Throughout this instruction manual, the term "vehicle" refers to any type of ground transportation, including but not limited to cars, vans, trucks, buses, motorcycles, bicycles, scooters, etc. Furthermore, "vehicle" is not limited by power source, and includes gasoline-powered vehicles, electric vehicles, hydrogen-powered vehicles, etc.

[0045] To address the problems in existing technologies, this invention provides an integrated automotive display device using a cholesteric LCD (Ch LCD), a color electronic paper technology made by stacking three layers of liquid crystal. These three layers reflect red, green, and blue light respectively to form a color image. Cholesteric LCD displays use different electric fields to control the rotation of liquid crystal particles, which remain bistable even when the electric field is turned off. By changing the three Ch LCD layers, it can display over 16.78 million vibrant colors. The advantages of cholesteric LCDs are: the bistable function consumes energy only during screen refresh and does not use power when displaying static images, thus the displayed content can be retained even when power is off. During the day, the displayed content is visible through reflection and is visible even in direct sunlight. In low-light environments such as at night, the cholesteric LCD can display content through a backlight panel integrated into the display device. Furthermore, this integrated automotive display device can be easily installed or integrated into the vehicle body, such as the front and rear bumpers, supporting larger display sizes and thus enabling the display of more content.

[0046] The various aspects of the present invention will now be described in detail.

[0047] Figure 1 This is a schematic diagram of an in-vehicle integrated display device 100 according to an embodiment of the present disclosure.

[0048] like Figure 1 As shown, the in-vehicle integrated display device 100 disclosed in this invention may include a cholesteric LCD panel (Ch-LCD) 106 and a backlight panel 108 disposed below the cholesteric LCD panel. In one embodiment of this invention, the cholesteric LCD panel 106 may include a three-layer cholesteric LCD panel with blue, green and red layers, respectively.

[0049] In one embodiment of the invention, in daytime use case 110, the cholesteric LCD panel 106 may be configured to display programmed graphics via reflection of ambient light 104 by the cholesteric LCD panel when the ambient light intensity is above a threshold. The automotive integrated display device 100 of the present invention can display more than 16.78 million colors by changing the three Ch-LCD layers. In another embodiment of the invention, the backlight panel 108 may be further configured to absorb a portion of the ambient light 104 when the ambient light intensity is above the threshold.

[0050] In the above embodiments of the present invention, the distinction between day and night can be made by an in-vehicle ambient light sensor. In a non-limiting example, when the in-vehicle ambient light sensor detects that the ambient light brightness around or inside the vehicle is higher than a threshold, it can be determined to be daytime and the determination result can be notified to the in-vehicle integrated display device 100. At this time, the in-vehicle integrated display device 100 can turn off the backlight panel 108 and display the programmed graphics by reflecting the ambient light through the cholesteric LCD panel 106 included in the in-vehicle integrated display device 100. In one embodiment of the present invention, the cholesteric LCD panel 106 can be further configured to start displaying the graphics when power is applied when the ambient light brightness is higher than the threshold and continue displaying the graphics after power is turned off. The cholesteric LCD panel 106 can use different electric fields to control the rotation of liquid crystal particles so that even after the electric field is turned off, the liquid crystal particles remain bistable to continue displaying graphics. This bistable function consumes power only during screen refresh and does not use power when displaying static images, so the displayed graphics can be retained when the power is off, resulting in lower power consumption and daytime graphics that are visible through reflections, and the screen is visible in direct sunlight.

[0051] As those skilled in the art will understand, the threshold used to determine ambient light brightness described above can be any suitable threshold, and is not limited to any specific threshold. For example, the threshold can be set to the ambient light brightness value required for the screen content to be visible to the human eye or to achieve other desired display effects without the backlight being turned on. Also, as those skilled in the art will understand, the aforementioned graphic can be any suitable graphic, such as a vehicle logo, and is not limited to any specific graphic. Furthermore, it should be understood that in the context of this disclosure, graphics also encompass text.

[0052] Figure 2 This is a schematic diagram of a cholesterol-type LCD panel in an in-vehicle integrated display device according to an embodiment of the present disclosure. Figure 2 As shown, the cholesterol-type LCD panel can be further configured to: use a corresponding electric field to rotate the liquid crystal particles into an isomorphic arrangement 202 to display white (reflecting ambient light 200 as white); use a corresponding electric field to rotate the liquid crystal particles into a mixed arrangement 204 to display various graphics (by causing the liquid crystal particles to reflect ambient light 200 as different shades of gray); and use a corresponding electric field to rotate the liquid crystal particles into a vertical alignment 206 to display black (reflecting ambient light 200 as black).

[0053] Back Figure 1 In nighttime use case 120, the backlight panel 108 may be configured to turn on when the ambient light intensity is below the threshold to provide illumination for the cholesteric LCD panel 106 to display graphics. In one embodiment of the invention, the cholesteric LCD panel 106 may be further configured to switch to transparent when the ambient light intensity is below the threshold to display programmed graphics via backlight illumination provided by the backlight panel 108.

[0054] In one embodiment of the invention, the backlight panel 108 may be a MiniLED. In other embodiments of the invention, the backlight panel may be any other suitable backlighting component, such as OLED, AMOLED, etc.

[0055] Figure 3 This is a schematic diagram of an in-vehicle integrated display device according to another embodiment of the present disclosure.

[0056] like Figure 3 As shown, the in-vehicle integrated display device 300 disclosed in this invention (corresponding to...) Figure 1 The illustrated integrated vehicle display device 100 can be mounted on the front bumper 314 of a vehicle (such as on a closed grille on the front bumper, etc.). As those skilled in the art will understand, in other embodiments of the invention, the integrated vehicle display device 300 can be mounted in any other suitable location, not limited to the front bumper. Figure 3 As shown, two in-vehicle integrated display devices 300 are arranged on the front bumper. As those skilled in the art will understand, more or fewer in-vehicle integrated display devices may be arranged, and it is not limited to arranging two.

[0057] In one embodiment of the present invention, such as Figure 3As shown, the vehicle-mounted integrated display device may further include a transparent cover 310, which may be made of PC material and may be disposed on top of the vehicle-mounted integrated display device to protect it. As those skilled in the art will understand, the transparent cover may be made of any other suitable material, not limited to PC material.

[0058] In one embodiment of the invention, the in-vehicle integrated display device may be further configured to display graphics when a user is detected approaching via an in-vehicle proximity sensor, allowing the user to interact with the graphics.

[0059] In another embodiment of the present invention, the in-vehicle integrated display device may optionally further include a touch-sensitive film 312, which may be disposed under the transparent cover and used for user interaction with the graphics. This interaction may include controlling the displayed graphics via touch or gestures (such as operating or switching). In the above embodiments of the present invention, users can control the displayed graphics or icons via the in-vehicle central control screen or a mobile app, such as switching to different graphics, turning the display of graphics on or off, etc.

[0060] In one embodiment of the present invention, such as Figure 3 As shown, the in-vehicle integrated display device may further include a PCB circuit board 316, which may be arranged at the bottom or side of the in-vehicle integrated display device. As those skilled in the art will understand, the PCB circuit board may be integrated with the cholesteric LCD panel 306 and the backlight panel 308 in any suitable manner, and is not limited to the manner described above.

[0061] as Figure 1 , Figure 3 The examples also illustrate daytime use case 310 and nighttime use case 320. The distinction between day and night is determined by ambient light intensity, which is also determined by an onboard ambient light sensor. In daytime use case 310, the backlight panel 308 is off, and the onboard integrated display device 300 displays programmed graphics through the reflection of ambient light 304 by the cholesteric LCD panel 306. In nighttime use case 320, the backlight panel 308 is on, and the onboard integrated display device 300 can switch the cholesteric LCD panel 306 to transparent and display programmed graphics through backlight illumination provided by the backlight panel 308.

[0063] like Figure 4As shown, method 400 begins at step 402, sensing the proximity of the user to the in-vehicle integrated display device. In one embodiment of the invention, this proximity can be determined by an in-vehicle proximity sensor.

[0064] Next, method 400 continues to step 404, whereby the vehicle-mounted integrated display device is used to display a programmed graphic when a user is sensed approaching the device. In one embodiment of the invention, step 404 may include displaying the graphic via the reflection of ambient light by a cholesteric LCD panel included in the vehicle-mounted integrated display device when the ambient light intensity is above a threshold; and displaying the graphic via illumination provided to the cholesteric LCD panel by a backlight panel included in the vehicle-mounted integrated display device when the ambient light intensity is below the threshold. In one embodiment of the invention, displaying the programmed graphic may further include: causing the cholesteric LCD panel to begin displaying the graphic when powered on and continue displaying the graphic after power is off when the ambient light intensity is above the threshold; and causing the cholesteric LCD panel to switch to transparent so that the graphic is displayed via backlight illumination provided by the backlight panel when the ambient light intensity is below the threshold.

[0065] Finally, method 400 continues to step 406, allowing the user to interact with the graphic via touch or gesture. In one embodiment of the invention, user interaction with the graphic can be performed via a touch-sensitive film included in the in-vehicle integrated display device.
