[0131] Meanwhile, the vehicle display device (100) according to the embodiment of the present disclosure may further include an external light sensor (711), an internal light sensor (713), or a user input unit (110).

[0132] The signal processing device (170) can output a control signal for varying the brightness of the first projection image (LTa) or the second projection image (LTb) based on the external illuminance (Cso) from the external illuminance sensor (711), the internal illuminance (Csi) from the internal illuminance sensor (713), or the setting input (Csp) from the user input unit (110).

[0133] For example, the signal processing device (170) can control the brightness of the first projection image (LTa) or the second projection image (LTb) to increase as the external illuminance (Cso) increases.

[0134] As another example, the signal processing device (170) can control the brightness of the first projection image (LTa) or the second projection image (LTb) to increase as the internal illuminance (Csi) decreases.

[0135] As another example, the signal processing device (170) can control the brightness of the first projection image (LTa) or the second projection image (LTb) to decrease as the setting input (Csp) decreases. Accordingly, the brightness of the first projection image (LTa) or the second projection image (LTb) projected on the first screen (SCRa) or the second screen (SCRb) can be varied.

[0136] Meanwhile, the image generation device (300) includes an optical output device (400) for optical output.

[0137] Meanwhile, the light output device (400) may include a light source (309) and a digital mirror device (308) that reflects light output from the light source (309).

[0138] For example, the light source (309) may include an LED diode or a laser diode.

[0139] Meanwhile, the digital mirror device (308) may be equipped with a plurality of digital mirrors. For example, it may be equipped with a digital micromirror device (DMD).

[0140] Meanwhile, the image generation device (300) may further include a digital mirror control unit (305) for controlling a digital mirror device (308) and a light source control unit (306) for controlling a light source (309).

[0141] In particular, the image generation device (300) has a processor (370), and the processor (370) may include a digital mirror control unit (305) for controlling a digital mirror device (308) and a light source control unit (306) for controlling a light source (309).

[0142] Meanwhile, the signal processing device (170) may be equipped with an image generation control unit (173) for controlling the image generation device (300) and a position control unit (174) for controlling the position or angle of a plurality of mirrors (310 to 330).

[0143]

[0144] Meanwhile, the signal processing device (170) can control the brightness of the first projection image (LTa) to be lower than the brightness of the second projection image (LTb) output from the light output device (400) for each frame, in order to reduce the brightness difference between the first projection image (LTa) projected on the first screen (SCRa) and the second projection image (LTb) projected on the second screen (SCRb).

[0145] For example, the signal processing device (170) can control the area corresponding to the first projection image (LTa) among the digital mirror devices (308) to be turned off during the first period.

[0146] At this time, the signal processing device (170) can control the area corresponding to the second projection image (LTb) among the digital mirror devices (308) to be switched on or off during the first period.

[0147] That is, the signal processing device (170) can control the number of times or frequency of off-times of an area corresponding to the first projection image (LTa) among the digital mirror devices (308) to be greater than that of an area corresponding to the second projection image (LTb) during the first period. Accordingly, the brightness of the first projection image (LTa) output from the light output device (400) becomes lower than that of the second projection image (LTb).

[0148] As another example, the signal processing device (170) can control, during the first period, at least a portion of the light source corresponding to the first projection image (LTa) to be turned off, and the light source corresponding to the second projection image (LTb) to be switched on or off.

[0149] That is, the signal processing device (170) can control the number of times or frequency of the light sources corresponding to the first projection image (LTa) to be turned off more frequently than the light sources corresponding to the second projection image (LTb) among the light sources (309) during the first period. Accordingly, the brightness of the first projection image (LTa) becomes lower than the brightness of the second projection image (LTb) output from the light output device (400).

[0150] Meanwhile, the signal processing device (170) may perform operation control of the digital mirror device (308) or operation control of the light source (309) based on external illuminance (Cso) from the external illuminance sensor (711), internal illuminance (Csi) from the internal illuminance sensor (713), or setting input (Csp) from the user input unit (110).

[0151] For example, the signal processing device (170) can control the brightness of the first projection image (LTa) to be smaller than the brightness of the second projection image (LTb) output from the light output device (400) for each frame as the external illuminance (Cso) increases.

[0152] As another example, the signal processing device (170) can control the brightness of the first projection image (LTa) to be lower than the brightness of the second projection image (LTb) output from the light output device (400) for each frame as the internal illuminance (Csi) decreases.

[0153] As another example, the signal processing device (170) can control the brightness of the first projection image (LTa) to be smaller than the brightness of the second projection image (LTb) output from the light output device (400) for each frame as the setting input (Csp) becomes smaller.

[0154] Figures 6a to 7 are drawings referred to in the description of Figure 4.

[0155] FIG. 6A is a diagram illustrating another example of the internal configuration of a vehicle display device according to one embodiment of the present disclosure.

[0156] Referring to the drawings, a vehicle display device (100aa) according to an embodiment of the present disclosure includes an image generating device (300) that outputs a projection image, a first screen (SCRa) on which a first projection image (LTa), which is a part of the projection images from the image generating device (300), is projected on one surface, a first mirror (310) that reflects a second projection image (LTb), which is another part of the projection images from the image generating device (300), a second mirror (320a) that reflects the second projection image (LTb) from the first mirror (310), and a second screen (SCRb) that is horizontally adjacent to the first screen (SCRa) and on which the second projection image (LTb) reflected by the second mirror (320a) is projected on one surface.

[0157] Meanwhile, unlike FIG. 4, the second mirror (320a) may be a concave mirror. Accordingly, an image can be stably displayed on the second screen (SCRb) which is larger than the first screen (SCRa).

[0158] That is, the curvature of the second mirror (320a) may be greater than that of the first mirror (310). For example, if the first mirror (310) is a flat mirror, the curvature is 0, so the curvature of the second mirror (320a), which is a concave mirror, may be greater. Accordingly, an image can be stably displayed on the second screen (SCRb) which is larger in size than the first screen (SCRa).

[0159] Meanwhile, the center (TEc) of the second mirror (320a) may be closer to the second screen (SCRb) than the ends (TEa, TEb) of the second mirror (320a). Accordingly, an image can be stably displayed on the second screen (SCRb) which is larger than the first screen (SCRa).

[0160] Meanwhile, according to FIG. 6a, among the a' and b' areas in the second projection image (LTb) output from the image generating device (300), the a' area, which is closer to the first screen (SCRa), can be reflected by the first mirror (310) and the second mirror (320a) and displayed in the a' area, which is closer to the first screen (SCRa), in the second screen (SCRb).

[0161] Meanwhile, according to FIG. 6a, among the a area and the b area in the second projection image (LTb) output from the image generating device (300), the b area, which is further apart from the first screen (SCRa), can be reflected by the first mirror (310) and the second mirror (320a) and displayed in the b area, which is further apart from the first screen (SCRa), in the second screen (SCRb).

[0162] That is, according to FIG. 6a, the second projection image (LTb) projected on the second screen (SCRb) may be a normal projection image rather than a reversed image.

[0163] FIG. 6b is a diagram illustrating another example of the internal configuration of a vehicle display device according to one embodiment of the present disclosure.

[0164] Referring to the drawings, a vehicle display device (100ab) according to an embodiment of the present disclosure includes an image generating device (300) that outputs a projection image, a first screen (SCRa) on which a first projection image (LTa), which is a part of the projection images from the image generating device (300), is projected on one surface, a first mirror (310) that reflects a second projection image (LTb), which is another part of the projection images from the image generating device (300), a second mirror (320b) that reflects the second projection image (LTb) from the first mirror (310), and a second screen (SCRb) that is horizontally adjacent to the first screen (SCRa) and on which the second projection image (LTb) reflected by the second mirror (320b) is projected on one surface.

[0165] Meanwhile, unlike FIG. 4, the second mirror (320b) may be a concave mirror. Accordingly, an image can be stably displayed on the second screen (SCRb) which is larger than the first screen (SCRa).

[0166] That is, the curvature of the second mirror (320b) may be greater than that of the first mirror (310). Accordingly, an image can be stably displayed on the second screen (SCRb) which is larger than the first screen (SCRa).

[0167] Meanwhile, the center (TE3) of the second mirror (320b) can be further away from the second screen (SCRb) than the ends (TE1, TE2) of the second mirror (320b). Accordingly, an image can be stably displayed on the second screen (SCRb) which is larger in size than the first screen (SCRa).

[0168] Meanwhile, according to FIG. 6b, among the areas a' and b in the second projection image (LTb) output from the image generating device (300), the area a that is closer to the first screen (SCRa) can be reflected by the first mirror (310) and the second mirror (320b) and displayed in the area a' that is spaced apart from the first screen (SCRa) in the second screen (SCRb).

[0169] Meanwhile, according to FIG. 6b, among the a area' and the b area' in the second projection image (LTb) output from the image generating device (300), the b area' that is further away from the first screen (SCRa) can be reflected by the first mirror (310) and the second mirror (320b) and displayed in the b' area that is closer to the first screen (SCRa) in the second screen (SCRb).

[0170] That is, according to FIG. 6b, the second projection image (LTb) projected on the second screen (SCRb) may be reversed.

[0171] Accordingly, the second projection image (LTb) output from the image generating device (300) of FIG. 6b may be an inverted image. Accordingly, the image can be stably displayed on the second screen (SCRb) which is larger in size than the first screen (SCRa).

[0172] Meanwhile, the first projection image (LTa) output from the image generating device (300) of FIG. 6b may be a normal projection image, unlike the second projection image (LTb).

[0173] Figure 7 is a drawing illustrating the change in position of the first mirror of Figure 4.

[0174] Referring to the drawings, a vehicle display device (100) according to one embodiment of the present disclosure includes an image generating device (300), a first screen (SCRa), a first mirror (310), a second mirror (320), and a second screen (SCRb), as shown in FIG. 4.

[0175] Meanwhile, a vehicle display device (100) according to one embodiment of the present disclosure may further include a first actuator (ACTa) that changes the position or angle of the first mirror (310).

[0176] Meanwhile, a vehicle display device according to one embodiment of the present disclosure further includes a signal processing device (170) that controls a first actuator (ACTa).

[0177] Meanwhile, the signal processing device (170) can control the size of the second projection image (LTb) projected onto the second screen (SCRb) to be varied based on the variation in the position or angle of the first mirror (310). Accordingly, while integrating multiple displays using a single image generating device (300), it is possible to vary the size of the image displayed on the second screen (SCRb).

[0178] Figure 7 (a) illustrates that the position of the first mirror (310) is located at the first position (PSa).

[0179] Accordingly, the second projection image (LTb) output from the image generating device (300) can be displayed on the first area (ARa) of the second screen (SCRb) through the first mirror (310) and the second mirror (320) located at the first position (PSa).

[0180] Figure 7 (b) illustrates that the position of the first mirror (310) is located at the second position (PSb).

[0181] The second position (PSb) may be further away from the first screen (SCRa) or closer to the second screen (SCRb) than the first position (PSa).

[0182] Accordingly, the second projection image (LTb) output from the image generating device (300) can be displayed on the second area (ARb) of the second screen (SCRb) through the first mirror (310) and the second mirror (320) located at the second position (PSb).

[0183] At this time, the size of the second area (ARb) may be smaller than the size of the first area (ARa), as shown in the drawing.

[0184] And, the second area (ARb) may be a part of the second screen (SCRb) and may be a part of the first screen (SCRa).

[0185] That is, when the position of the first mirror (310) is the second position (PSb), the projection image may not be displayed in an area adjacent to the first screen (SCRa), which is another part of the second screen (SCRb).

[0186] FIG. 8 is a drawing illustrating an example of the internal configuration of a vehicle display device according to another embodiment of the present disclosure.

[0187] Referring to the drawings, a vehicle display device (100b) according to another embodiment of the present disclosure includes an image generating device (300) that includes an optical output device (400) and outputs a projection image, a first screen (SCRa) on which a first projection image (LTa), which is a part of the projection images from the image generating device (300), is projected on one surface, a first mirror (310) that reflects a second projection image (LTb), which is another part of the projection images from the image generating device (300), a second mirror (320) that reflects the second projection image (LTb) from the first mirror (310), a third mirror (330) that reflects a third projection image (LTc), which is another part of the projection images from the image generating device (300), and a second mirror (330) that is horizontally adjacent to the first screen (SCRa) and on which at least one of the second projection image (LTb) or the third projection image (LTc) reflected by the second mirror (320) is projected on one surface. Includes a second screen (SCRb) onto which the projection is made.

[0188] Accordingly, it is possible to integrate and implement multiple displays using a single image generating device (300). In particular, it is possible to integrate and implement a cluster display and a center information display using a single image generating device (300).

[0189] That is, unlike the vehicle display device (100) of FIG. 4, the vehicle display device (100b) of FIG. 8 is different in that it further includes a third mirror (330) that reflects a third projection image (LTc), which is another part of the projection image from the image generating device (300).

[0190] Additionally, the second mirror (320) can further reflect the third projection image (LTc) from the third mirror (330). Accordingly, it is possible to integrate multiple displays using a single image generating device (300).

[0191] Meanwhile, a second projection image (LTb) can be displayed on a first area (ARma) of a second screen (SCRb), and a third projection image (LTc) can be displayed on a second area (ARmb) of the second screen (SCRb). Accordingly, multiple images can be displayed on the second screen (SCRb).

[0192] Meanwhile, the image generating device (300) can output a second projection image (LTb) between the first projection image (LTa) and the third projection image (LTc), as shown in the drawing.

[0193] Accordingly, a third projection image (LTc) can be displayed on an area (ARmb) of the second screen (SCRb) that is closer to the first screen (SCRa), and a second projection image (LTb) can be displayed on an area (ARma) that is further away from the first screen (SCRa). Consequently, it is possible to integrate and implement multiple displays using a single image generating device (300).

[0194] Meanwhile, the optical path of the second projection image (LTb) and the optical path of the third projection image (LTc) can be separated as shown in the drawing.

[0195] That is, the third projection image (LTc) reflected from the third mirror (330) can be incident on the second mirror (320) while being spaced apart from the first mirror (310). Accordingly, it is possible to integrate and implement multiple displays using one image generating device (300).

[0196] Meanwhile, the first mirror (310) may be a flat mirror, and the second mirror (320) or the third mirror (330) may be a concave mirror.

[0197] For example, the curvature of the second mirror (320) or the third mirror (330) may be greater than that of the first mirror (310). Accordingly, an image can be stably displayed on the second screen (SCRb) which is larger than the first screen (SCRa).

[0198] Meanwhile, the second mirror (320) may have the center of the second mirror (320) closer to the second screen (SCRb) than the end of the second mirror (320), as shown in FIG. 6a, or the center of the second mirror (320) may be further away from the second screen (SCRb) than the end of the second mirror (320), as shown in FIG. 6b.

[0199] FIG. 9 is a drawing illustrating an example of the internal configuration of a vehicle display device according to another embodiment of the present disclosure.

[0200] Referring to the drawings, a vehicle display device (100ba) according to another embodiment of the present disclosure includes an image generating device (300), a first screen (SCRa), a first mirror (310), a second mirror (320), a third mirror (330), and a second screen (SCRb), as shown in FIG. 7.

[0201] However, unlike in Fig. 8, there is a difference in that the optical path of the second projection image (LTb) and the optical path of the third projection image (LTc) are not separated but partially overlap each other.

[0202] That is, at least a portion of the third projection image (LTc) reflected from the third mirror (330) can be transmitted through the first mirror (310) and incident on the second mirror (320).

[0203] Meanwhile, the first mirror (310) can reflect the second projection image (LTb) whose incident angle is less than a predetermined angle and transmit the third projection image (LTc) whose incident angle is greater than a predetermined angle.

[0204] That is, the angle of the second projection image (LTb) incident on the first mirror (310) may be smaller than the angle of the third projection image (LTc).

[0205] Accordingly, the first mirror (310) selectively transmits or reflects, so that the third projection image (LTc) reflected from the third mirror (330) and the second projection image (LTb) reflected from the first mirror (310) can be incident on different areas of the second mirror (320), respectively.

[0206] Accordingly, a third projection image (LTc) can be displayed on an area (ARmb) of the second screen (SCRb) that is closer to the first screen (SCRa), and a second projection image (LTb) can be displayed on an area (ARma) that is further away from the first screen (SCRa). Consequently, it is possible to integrate and implement multiple displays using a single image generating device (300).

[0207] Figures 10a to 11b are drawings referenced in the description of Figure 8 or Figure 9.

[0208] FIG. 10a and FIG. 10b illustrate the change in position of the first mirror (310) in the vehicle display device (100b) of FIG. 8 or the vehicle display device (100ba) of FIG. 9.

[0209] First, FIG. 10a illustrates that the first mirror (310) is at the first position (PS1).

[0210] Referring to the drawings, the vehicle display device (100b) of FIG. 8 or the vehicle display device (100ba) of FIG. 9 includes an image generating device (300), a first screen (SCRa), a first mirror (310), a second mirror (320b) which is a concave mirror, a third mirror (330b) which is a concave mirror, and a second screen (SCRb).

[0211] Meanwhile, the vehicle display device (100b) of FIG. 8 or the vehicle display device (100ba) of FIG. 9 may further include a first actuator (ACTa) that changes the position or angle of the first mirror (310) and a signal processing device (170) that controls the first actuator (ACTa).

[0212] Meanwhile, the signal processing device (170) can control the size of the second projection image (LTb) projected on the second screen (SCRb) to be varied based on the variation of the position or angle of the first mirror (310).

[0213] Meanwhile, the signal processing device (170) can control the type or number of projection images projected onto the second screen (SCRb) to vary based on the variation of the position or angle of the first mirror (310).

[0214] As shown in Fig. 10a, when the first mirror (310) is at the first position (PS1), the image generating device (300) may output the first projection image (LTa) and the second projection image (LTb), and may not output the third projection image.

[0215] Meanwhile, the signal processing device (170) can control the first mirror (310) to be positioned at the first position (PS1) when outputting the first projection image (LTa) and the second projection image (LTb).

[0216] Accordingly, when the image generating device (300) outputs the first projection image (LTa) and the second projection image (LTb), the first projection image (LTa) can be displayed on the first screen (SCRa) and the second projection image (LTb) can be displayed on the second screen (SCRb).

[0217] In the drawing, at a first time point (T1), the first mirror (310) is at a first position (PS1), and the image generating device (300) outputs a first projection image (LTa) and a second projection image (LTb), so that the first projection image (LTa) is displayed on the first screen (SCRa), and the second projection image (LTb) is displayed on the area (ARt) of the second screen (SCRb).

[0218] Next, Figure 10b illustrates that the first mirror (310) is at the second position (PS2).

[0219] Referring to the drawing, when the first mirror (310) is at the second position (PS2), the image generating device (300) can output a first projection image (LTa), a second projection image (LTb), and a third projection image (LTc).

[0220] At this time, the second position (PS2) may be a position further away from the first screen (SCRa) or closer to the second screen (SCRb) than the first position (PS1).

[0221] Meanwhile, the signal processing device (170) can control the first mirror (310) to be positioned at the second position (PS2) when outputting the first projection image (LTa), the second projection image (LTb), and the third projection image (LTc).

[0222] Accordingly, when the image generating device (300) outputs a first projection image (LTa), a second projection image (LTb), and a third projection image (LTc), the first projection image (LTa) can be displayed on the first screen (SCRa), and the second projection image (LTb) and the third projection image (LTc) can be displayed on the second screen (SCRb).

[0223] In the drawing, at a second time point (T2), the first mirror (310) is at a second position (PS2), and the image generating device (300) outputs a first projection image (LTa), a second projection image (LTb), and a third projection image (LTc), so that the first projection image (LTa) is displayed on the first screen (SCRa), the second projection image (LTb) is displayed on the first area (ARt1) of the second screen (SCRb), and the third projection image (LTc) is displayed on the second area (ARt2).

[0224] At this time, the second area (ARt2) of the second screen (SCRb) can operate as a CID display, and the first area (ARt1) of the second screen (SCRb) can operate as a PID (Passenger Information Display) display. Accordingly, it is possible to integrate and implement multiple displays using a single image generating device (300).

[0225] Figures 11a and 11b illustrate the display of ambient lighting by the movement of the second mirror of Figure 9.

[0226] FIG. 11A is a diagram illustrating an example of the internal configuration of a vehicle display device according to another embodiment of the present disclosure.

[0227] Referring to the drawings, a vehicle display device (100bc) according to another embodiment of the present disclosure includes an image generating device (300), a first screen (SCRa), a first mirror (310), a second mirror (320b) which is a concave mirror, a third mirror (330b) which is a concave mirror, and a second screen (SCRb).

[0228] Meanwhile, a vehicle display device (100bc) according to another embodiment of the present disclosure may further include a second actuator (ACTb) that changes the position or angle of the second mirror (320).

[0229] Meanwhile, a vehicle display device (100bc) according to another embodiment of the present disclosure may further include a signal processing device (170) for controlling a second actuator (ACTb).

[0230] Meanwhile, the second mirror (320b) operates in a fixed position in normal mode and can move up and down depending on the ambient lighting mode.

[0231] That is, the signal processing device (170) can control the second mirror (320b) to be fixed in normal mode, and control the second mirror (320b) to move up and down in ambient lighting mode.

[0232] For example, in normal mode, the position of the second mirror (320b) is fixed, so it can operate as in Fig. 10a.

[0233] That is, when the image generating device (300) outputs a first projection image (LTa) and a second projection image (LTb), the first projection image (LTa) can be displayed on the first screen (SCRa) and the second projection image (LTb) can be displayed on the second screen (SCRb).

[0234] As another example, in the ambient lighting mode, the second mirror (320b) moves up and down, the first projection image (LTa) is displayed on the first screen (SCRa), and the second projection image (LTb) is displayed on the second screen (SCRb), and some light may be displayed like ambient lighting on the upper or lower part of the second screen (SCRb) due to the up and down movement of the second mirror (320b).

[0235] Meanwhile, in the ambient lighting mode, the first projection image (LTa) is displayed on the first screen (SCRa), the second projection image (LTb) is not displayed on the second screen (SCRb), and some light may be displayed like ambient lighting on the upper or lower part of the second screen (SCRb) due to the up and down movement of the second mirror (320b).

[0236] To this end, in ambient lighting mode, the image generating device (300) can output a second projection image for lighting, rather than a second projection image for image display.

[0237] That is, the second projection image output from the image generation device (300) may be smaller in size in ambient lighting mode compared to in normal mode.

[0238] Figure 11b illustrates that ambient lighting is implemented on the upper part of the second screen (SCRb).

[0239] Referring to the drawing, the second projection image (LTb) is not displayed on the second screen (SCRb), and some light may be displayed on the upper part of the second screen (SCRb) as ambient lighting (LLD) due to the up-and-down movement of the second mirror (320b). Accordingly, ambient lighting, etc. inside the vehicle can be easily implemented.

[0240] FIG. 12 is a drawing illustrating the appearance of a vehicle display device according to another embodiment of the present disclosure.

[0241] Referring to the drawings, a vehicle display device (100m) according to another embodiment of the present disclosure includes, similarly to FIG. 2, an image generating device (300) that outputs a projection image, a first mirror (310) that reflects a second projection image (LTb), which is another part of the projection image from the image generating device (300), and a second mirror (320) that reflects the second projection image (LTb) from the first mirror (310).

[0242] However, the vehicle display device (100m) according to another embodiment of the present disclosure is implemented by integrating it into one screen instead of two screens, unlike FIG. 2.

[0243] That is, a vehicle display device (100m) according to another embodiment of the present disclosure includes an image generating device (300) that outputs a projection image, a first mirror (310) that reflects a second projection image (LTb) that is another part of the projection image from the image generating device (300), a second mirror (320) that reflects the second projection image (LTb) from the first mirror (310), and a screen (SCR) on which the first projection image (LTa) that is a part of the projection image from the image generating device (300) is projected onto one area (ARn1), and the second projection image (LTb) reflected from the second mirror (320) is projected onto another area (ARn2).

[0244] Accordingly, one area (ARn1) of the screen (SCR) can operate as a cluster display (180a), and another area (ARn2) of the screen (SCR) can operate as a CID display (180b).

[0245] Ultimately, it becomes possible to integrate and implement multiple displays (180a, 180b) using one image generating device (300).

[0246] Although the preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above, and various modifications may be made by a person skilled in the art to which the present invention pertains without departing from the gist of the present disclosure as claimed in the claims, and such modifications should not be understood individually from the technical idea or prospect of the present disclosure.
