[0002] This application claims priority to Korean Patent Application No. 10-2020-0073028, filed on June 16, 2020, the entire contents of which are incorporated herein by reference for various purposes. Technical Field

[0003] This invention relates to a vehicle and an image display method for the vehicle, for preventing the display colors from being distorted according to the driver's viewing angle. Background Technology

[0004] To support and improve vehicle functionality, various types of displays are installed in vehicles. For example, navigation systems, which are installed in vehicles and provide route guidance to destinations, are widely used.

[0005] A navigation system is a device that matches the current location with map information to provide a route from the driver's current location to the destination set by the driver. Navigation systems tend to feature high-performance displays to provide various types of information for the driver's convenience and to display route information. Therefore, organic light-emitting diode (OLED) displays, with their higher response speed, brightness, and contrast compared to traditional liquid crystal displays, are gaining increasing attention.

[0006] In OLED displays, microcavities are often used, in which a cathode and anode are formed of metallic materials and a light-emitting layer is placed between them to improve optical efficiency. In OLED displays using microcavity structures, the colors on the front and sides of the panel differ as the viewing angle moves from the front to the side. This causes color shift and reduces the color reproducibility of R, G, and B.

[0007] However, since the display of the navigation system in the vehicle is positioned to the side of the driver's line of sight, it is difficult to avoid the degradation of clarity depending on the viewing angle when using an OLED display as the navigation system's display.

[0008] The information disclosed in the background section of this invention is only intended to enhance the understanding of the overall background of this invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

While the invention will be described in conjunction with exemplary embodiments thereof, it should be understood that this description is not intended to limit the invention to these exemplary embodiments. Rather, the invention is intended to cover not only these exemplary embodiments thereof, but also various alternatives, modifications, equivalents and other embodiments that may be included within the spirit and scope of the invention as defined by the appended claims.

[0030] A detailed description of exemplary embodiments of the present invention will be provided to enable those skilled in the art to implement and practice the invention with reference to the accompanying drawings. However, the invention can be implemented in various different forms and is not limited to the exemplary embodiments described herein. Furthermore, for clarity in the accompanying drawings, components irrelevant to the description will be omitted, and throughout the specification, the same reference numerals will be used to denote the same or similar components.

Additionally, throughout this specification, the same or similar elements are indicated by the same reference numerals.

[0033] In the following description, embodiments of the invention will be described with reference to the accompanying drawings. In the description below, detailed descriptions of known technologies related to this description are omitted if they would unnecessarily obscure the essential points of this description. Component names used in the specification have been chosen for ease of description and may differ from component names in actual products.

[0034] Figure 1 This is a schematic diagram illustrating examples of vehicles according to various exemplary embodiments of the present invention.

[0035] like Figure 1 As shown, a display 200 for displaying a navigation screen S can be installed in the vehicle. The navigation display 200 can be installed between the driver's seat and the passenger seat.

[0036] Display 200 can be an OLED display. OLEDs have a structure in which an organic light-emitting layer is formed between a cathode for injecting electrons and an anode for injecting holes. Microcavity structures can be applied to OLED displays to improve light efficiency. A microcavity has a structure in which the cathode is formed of a metallic material to serve as a reflective electrode, the anode is formed as a layered structure of indium tin oxide (ITO) and Ag layers, and an optical cavity is formed between the cathode and the anode.

[0037] In OLED displays employing microcavity structures, the optical path difference (OPD) between constructive lights decreases as the viewing angle moves from the front to the side of the display panel, and the enhancement wavelength range shifts along shorter wavelengths. Consequently, the colors on the front and sides of the panel differ, potentially leading to color shift. This invention aims to address this color shift problem and proposes a method to compensate for RGB image data by applying gain in real-time based on the driver's position.

[0038] Figure 2 This is a block diagram illustrating examples of vehicle configurations according to various exemplary embodiments of the present invention, with emphasis on components relating to exemplary embodiments of the present invention.

[0039] Reference Figure 2 The vehicle according to various exemplary embodiments of the present invention includes: a display 200 for displaying image data, a camera 100 for capturing images of the driver, an eye-tracking unit 320, a gain compensation table 330, and a display controller 310 for controlling these components.

[0040] The display 200 can display navigation information and various types of information convenient for the driver. In an exemplary embodiment, the display 200 can be an OLED display employing a microcavity structure.

[0041] Camera 100 captures an image of the driver's face while sitting in the driver's seat and provides the image to eye-tracking unit 320.

[0042] The gaze tracking unit 320 tracks the movement of the driver's face and the movement of the pupils of the eyes based on an image of the driver's face. The gaze tracking unit 320 can determine the position of the driver's gaze in real time by performing gaze tracking (i.e., eye tracking). The gaze tracking unit 320 can detect the movement of the pupils of the eyes by analyzing images captured by the camera 100 and determine the driver's gaze based on the detected movement. Although methods for tracking gaze using video analysis of a camera have been described in various exemplary embodiments of the invention, eye tracking techniques such as contact lens methods and sensor attachment methods can also be applied.

[0043] Gain compensation table 330 stores gain values ​​based on the angle formed between the display 200 and the driver's line of sight. Gain compensation table 330 stores gain values ​​used to correct color shifts in the display 200 for various viewing angles. For example, at a resolution of 1920×720, each pixel can store a gain of 1920×(0° to 90°)×(3(R,G,B)×1° viewing angle). Gain compensation requires controlling the gain of the RGB data to achieve the desired color and can be set with reference to the CIE1931 coordinate system, which is the commonly used color coordinate system. Figure 3 The CIE 1931 coordinate system is shown. (Refer to...) Figure 3 If the red coordinates (0.34, 0.32) are measured when the input data is (128, 128, 128), the color change can be corrected to (128, 140, 140) and white (0.31, 0.32) by increasing the gain of green (G) and blue (B) by 10%. The gain compensation table 330 can be stored in a timing controller or H / U memory included in the display 200. Furthermore, in the gain compensation table 330, the angle formed between the display 200 and the driver can include both horizontal and vertical angles. Therefore, the gain compensation table 330 can store gain values ​​based on the horizontal angle, gain values ​​based on the vertical angle, and gain values ​​based on a combination of horizontal and vertical angles. For example, in the case of horizontal compensation, 90 gain values ​​can be stored in 1° units within the range of 0° to 90° based on the driver. When vertical compensation is required, 180 gain values ​​can be stored in 1° units within the range of -90° to 90° in the vertical direction. Therefore, color compensation for angles from 0° to 90° in the horizontal direction and from -90° to 90° in the vertical direction can be performed based on a combination of 90 gain values ​​in the horizontal direction and 180 gain values ​​in the vertical direction. Here, to minimize the data in the gain compensation table 330, the effective angle between the driver and the display can be limited to a range of 10° to 70° in the horizontal direction and -60° to 20° in the vertical direction. Considering memory efficiency, the size of the gain compensation table 330 can be reduced to 1×2 or 1×4, and when applying gain per frame, a gain of 2×2 or 4×4 can be applied.

[0044] The display controller 310 determines the angle between the display 200 and the driver's line of sight based on the tracking results of the gaze tracking unit 320, loads the gain value corresponding to the determined angle from the gain compensation table 330, applies the gain value to the image data, and displays the image data with the applied gain value on the display 200. The display controller 310, which performs this control function, may include an image signal output unit 312, a gain application unit 314, and an angle calculation unit 316.

[0045] The angle calculation unit 316 can determine the angle in the horizontal and vertical directions between the user's line of sight and the center point of the display 200 based on the tracking results of the eye tracking unit 320.

[0046] The gain application unit 314 can load gain values ​​corresponding to the angles determined by the angle calculation unit 316 from the gain compensation table 330 and apply the loaded gain values ​​to the image data. Flash memory can be used for the gain compensation table 330, and SRAM can be used for the gain application unit 314. The gain application unit 314 can perform only horizontal compensation or both vertical and horizontal compensation depending on the aspect ratio of the display 200. For example, for displays with aspect ratios of 24:9 and 32:9, the vertical length is shorter, so the effect of color changes in the vertical direction is not significant. Therefore, only horizontal compensation can be performed on such displays. The gain application unit 314 can apply the gain value corresponding to the horizontal angle between the display 200 and the driver's line of sight to only one row, and apply the gain value corresponding to the vertical angle on a frame-by-frame basis. Here, when the gain application unit 314 applies gain in 2° units instead of 1° units and performs linear interpolation, the size of the gain compensation table 330 can be minimized to save memory. At the same time, when the driver's position changes rapidly, the color compensation value increases, so the difference can be perceived. Therefore, the gain application unit 314 can sequentially control the gain value in 1-second drive frequency steps, thereby minimizing the perceived difference. Furthermore, even when compensation is applied when the driver's position changes slightly, frequent compensation can cause a perceived difference. Therefore, a subtle motion (e.g., approximately + / - 5°) can be set as a reference value based on the current angle, and compensation can be performed only for motions equal to or greater than the reference value. Additionally, continuous subtle motions can be detected, and when a change of + / - 5° from the initial position occurs, the current position can be updated, and then the gain value can be applied to minimize the perceived difference caused by frequent compensation.

[0047] The image signal output unit 312 can output the image data with the gain value applied in the gain application unit 314 to the display 200.

[0048] According to this configuration, the vehicle according to an exemplary embodiment of the present invention can apply gain in real time to compensate for the color of image data based on the driver's position, and then display the compensated image data on the display 200. Therefore, the problem of undesirable colors being displayed due to the angular difference between the display 200 and the driver's line of sight can be solved.

[0049] Figure 4 This is a flowchart describing an image display method according to various exemplary embodiments of the present invention.

[0050] Reference Figure 4 The eye-tracking unit 320 tracks the driver's gaze in real time and outputs the tracking results (S110). The eye-tracking unit 320 can use methods such as image analysis, contact lens methods, or sensor attachment methods to track changes in the driver's gaze in real time.

[0051] The angle calculation unit 316 of the display controller 310 determines the angle formed between the driver's line of sight and the display 200 based on the tracking results of the eye tracking unit 320 (S120). The angle calculation unit 316 can determine the angle between the driver's line of sight and the center point of the display 200 in the horizontal or vertical direction.

[0052] The gain application unit 314 of the display controller 310 loads the gain value corresponding to the angle determined in the angle calculation unit 316 from the gain compensation table 330 (S130).

[0053] The display controller 310 can apply the applied gain to the image data and display the color-compensated image data on the display 200 (S140).

[0054] Figure 5 This is a diagram illustrating a method for compensating image data using an image display method according to various exemplary embodiments of the present invention, and shows the case of compensating for color in the horizontal direction.

[0055] When the display 200 has an aspect ratio of 24:9 or 32:9, the vertical length is relatively short, so color changes in the vertical direction are not obvious. Therefore, only horizontal compensation can be performed on the display. In the case of horizontal compensation, 90 gain values ​​from 0° to 90° in 1° increments can be stored in the gain compensation table 330.

[0056] The camera 100 tracks the driver's line of sight, and then the horizontal angle between the driver's line of sight and the display 200 can be determined.

[0057] A comparison is made between a 30° horizontal angle and a 45° horizontal angle. Compared to the 45° angle, the driver is farther from the center of the display 200 at a 30° angle. That is, color shift may become severe at a 30° horizontal angle. Therefore, the gain value of the gain compensation table 330 can be set higher at 30°. When compensating for color shift at horizontal angles, the gain application unit 314 can apply the gain value corresponding to the horizontal angle between the display 200 and the driver's line of sight to only one row.

[0058] Figure 6 This is a diagram illustrating a method for compensating image data using an image display method according to various exemplary embodiments of the present invention, and shows the case of compensating for color in the vertical direction.

[0059] Using camera 100 to track the driver's line of sight, the angle between the driver's line of sight and display 200 in the vertical direction can be determined. Figure 6 The following scenario illustrates that, with the angle between the driver's line of sight and the display 200 fixed at 45°, the angle of the driver's head position changes vertically to 0°, 15°, and 30°.

[0060] When horizontal and vertical compensation is required, 180 gain values ​​can be set in the gain compensation table 330 in the vertical direction from -90° to 90° in 1° increments. Therefore, color compensation from 0° to 90° in the horizontal direction and from -90° to 90° in the vertical direction can be performed based on the combination of the 90 gain values ​​in the horizontal direction and the 180 gain values ​​in the vertical direction. Figure 6 Gain compensation table 330 shows the gain table applied in a 1920×1920 resolution display when the angle between the driver's line of sight and the display is 45° to the left and the vertical elevation angle is 0°. When performing vertical and horizontal compensation in this way, gain can be applied on a per-frame basis to perform color compensation.

[0061] Figure 7 This is a diagram illustrating a method for compensating image data using an image display method according to various exemplary embodiments of the present invention, and showing a method for preventing the perception of difference due to sudden color compensation when the driver's position changes rapidly.

[0062] When at least one of the horizontal and vertical angles between the display and the driver's line of sight changes from or exceeds the reference angle within a predetermined time—that is, when the driver's position changes rapidly—the gain value may increase rapidly. This rapid increase in gain causes a rapid change in the color compensation value, making the driver potentially perceive rapid color changes in the image data. In this way, when the display color changes rapidly due to a rapid change in the driver's position, the driver may perceive a difference.

[0063] Therefore, in various exemplary embodiments of the present invention, such as Figure 7 As shown, image data can be corrected by sequentially controlling the gain value using a 1-second drive frequency step. That is, when the compensation value changes rapidly, the image data can be compensated by sequentially changing the gain value every 1 second per frame, instead of reflecting the rapidly changing compensation value in real time in the image data.

[0064] Figure 8 This is a diagram illustrating a method for compensating image data using an image display method according to various exemplary embodiments of the present invention, and showing a method for preventing the perception of difference due to frequent compensation when compensation is applied even when the driver makes subtle movements.

[0065] The display controller 310 can check the driver's current position (S210) and determine whether the driver's position has changed (S220). Because the eye-tracking unit 320 tracks the driver's gaze in real time and outputs the tracking results, the display controller 310 can check the driver's current position and the changed position based on the tracking results of the eye-tracking unit 320.

[0066] The display controller 310 determines the change in the driver's line of sight, that is, whether the change in the angle between the display 200 and the driver is + / -5° (S230). Here, + / -5° is a reference value used to determine whether the driver's movement is reflected in the compensation, and the reference value can be changed in various ways according to the system design method.

[0067] When it is determined that the driver's line of sight has changed by + / -5°, a gain is applied to the image data to correct the image data (S240).

[0068] If the change is not + / -5°, determine whether the current position has changed by + / -5° or more relative to the initial position (S260).

[0069] When the current position changes by + / -5° or more relative to the initial position, both the current position and the initial position are updated (S270), and a gain is applied to the image data to correct the image data based on the angle change (S240).

[0070] When the current position changes by less than + / -5° relative to the initial position, no compensation is performed, and the driver's current position is updated (S250). Therefore, when the driver's subtle movements accumulate, and when the driver's position changes by + / -5° relative to the initial position, a gain can be applied to the image data to correct the image data.

[0071] As described above, the present invention can prevent display colors from being distorted due to viewing angle by compensating for display colors in real time in response to the driver's viewing angle.

[0072] Furthermore, when using a navigation system employing an OLED display, the present invention can prevent the display of undesirable colors based on the driver's viewing angle. In particular, when using an OLED with microcavities, it can prevent viewing angle-based color shift and brightness degradation, and improve color reproducibility and external visibility.
