[0106] At this time, the first guest virtual machine (not shown) can operate for the first display 180a, and the second guest virtual machine (not shown) can operate for the second display 180b or the third display 180h.

[0107] On the other hand, the signal processing device 170 can process various signals such as audio signals, video signals, and data signals. Therefore, the signal processing device 170 can be implemented as a system on chip (SOC).

[0108] The vehicle display device 100 of the present invention may also have a plurality of actuators (ACTa~ACTc) that change the position or angle of the plurality of mirrors or screens Scr, as described later.

[0109] Figures 4a to 4e The figure is referenced in the explanation of the operation of the vehicle display device according to an embodiment of the present invention.

[0115] Figure 4cFor example, the first projected image projected onto the screen Scr, which serves as the first display 180a, is the third size Arb2, and the second projected image projected onto the windshield WS, which serves as the third display 180h, is the fourth size Ara2.

[0116] As shown in the figure, the third dimension Arb2 can be smaller than the fourth dimension Ara2. For example, the third dimension Arb2 can be approximately 0.5 times the fourth dimension Ara2.

[0117] Figure 4d An example is shown where the first projected image projected onto the screen Scr, which serves as the first display 180a, is the fifth size Arb3, and there is no projected image projected onto the windshield WS, which serves as the third display 180h.

[0118] As shown in the figure, the fifth dimension Arb can be Figure 4b The sum of the first dimension Arb and the second dimension Ara, or Figure 4c The sum of the third dimension Arb2 and the fourth dimension Ara2.

[0119] Figure 4e For example, there is no projected image projected onto the screen Scr, which serves as the first display 180a, and the second projected image projected onto the windshield WS, which serves as the third display 180h, is the sixth size Ara4.

[0120] As shown in the figure, the sixth dimension Ara4 can be Figure 4b The sum of the first dimension Arb and the second dimension Ara, or Figure 4c The sum of the third dimension Arb2 and the fourth dimension Ara2.

[0121] like Figures 4b to 4d As shown, a vehicle display device 100 according to an embodiment of the present invention uses an actuator to change the size of a first projected image projected onto a screen Scr. Thus, a plurality of displays can be integrated using a single image generation device 300, while simultaneously changing the size of the dashboard display.

[0122] On the other hand, such as Figures 4b to 4d As shown, in one embodiment of the present invention, a vehicle display device 100 uses an actuator to change the size of a second projected image projected onto the windshield WS. Thus, a plurality of displays can be integrated using a single image generation device 300, while simultaneously changing the size of the head-up display.

[0123] Figure 5 This is an example of an internal block diagram illustrating an embodiment of the present invention for a vehicle display device.

[0124] Referring to the accompanying drawings, an embodiment of the vehicle display device 100 of the present invention includes: an image generating apparatus 300, including a light output device 400, for outputting a projected image; a first reflector 310 for reflecting a first projected image LTa, which is a part of the projected image from the image generating apparatus 300; a screen Scr, on which the first projected image LTa reflected by the first reflector 310 is projected onto one side; a second reflector 320 for reflecting a second projected image LTb, which is another part of the projected image from the image generating apparatus 300, onto a windshield WS; and a first actuator ACTa for changing the position or angle of the first reflector 310.

[0125] On the other hand, a first projected image LTa, which is part of the projected image output from the image generating device 300, is projected onto one side of the screen Scr via the first reflector 310. Thus, an instrument panel image can be displayed on the first display 180a, which includes the screen Scr.

[0126] On the other hand, a second projected image LTb, which is another part of the projected image output from the image generating device 300, is projected onto one side of the windshield WS via the second reflector 320. Thus, various information or images can be displayed on the third display 180h, which includes the windshield WS.

[0127] On the other hand, the size of the first projected image LTa projected onto the screen Scr changes based on the change in the position or angle of the first reflector 310. Thus, a plurality of displays can be integrated using a single image generation device 300, while simultaneously changing the size of the dashboard display.

[0128] On the other hand, the size of the second projected image LTb reflected onto the windshield WS can be changed based on the change in the position or angle of the first reflector 310. Thus, a plurality of displays can be integrated using a single image generation device 300, while simultaneously changing the size of the head-up display.

[0129] On the other hand, a vehicle display device 100 according to an embodiment of the present invention may further include a signal processing device 170 for controlling a first actuator ACTa.

[0130] On the other hand, the signal processing device 170 can control the size of the first projected image LTa projected onto the screen Scr to change based on the change in the position or angle of the first reflector 310. Thus, a plurality of displays can be integrated using a single image generation device 300, while simultaneously changing the size of the dashboard display.

[0131] On the other hand, the signal processing device 170 can control the size of the second projected image LTb reflected on the windshield WS to change based on the change in the position or angle of the first reflector 310. Thus, a plurality of displays can be integrated using a single image generation device 300, while simultaneously changing the size of the head-up display.

[0132] On the other hand, the signal processing device 170 can control the image generation device 300.

[0133] On the other hand, the signal processing device 170 can control the brightness of the first projected image LTa or the second projected image LTb to be at a first level in the first mode, and at a second level in the second mode. Thus, the brightness of the first projected image LTa or the second projected image LTb can be changed.

[0134] On the other hand, the vehicle display device 100 of the present invention may also include an external illuminance sensor 711, an internal illuminance sensor 713, or a user input unit 110.

[0135] The signal processing device 170 can output a control signal for changing the luminance of the first projected image LTa or the second projected 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.

[0136] For example, the signal processing device 170 can control the brightness of the first projected image LTa or the second projected image LTb to increase as the external illuminance Cso increases.

[0137] As another example, the signal processing device 170 can control the brightness of the first projected image LTa or the second projected image LTb to increase as the internal illuminance Csi decreases.

[0138] As another example, the signal processing device 170 can control the brightness of the first projected image LTa or the second projected image LTb to decrease as the setting input Csp decreases. This allows the brightness of the first projected image LTa projected onto the screen Scr or the second projected image LTb projected onto the windshield WS to be changed.

[0139] On the other hand, the image generating apparatus 300 includes a light output device 400 for light output.

[0140] On the other hand, the light output device 400 may include a light source 309 and a digital reflector device 308 that reflects the light output from the light source 309.

[0141] For example, light source 309 may include LED diodes or laser diodes, etc.

[0142] On the other hand, the digital mirror device 308 may have a plurality of digital mirrors. For example, it may have a digital micromirror device (DMD).

[0143] On the other hand, the image generating apparatus 300 may also include a digital mirror control unit 305 for controlling the digital mirror device 308 and a light source control unit 306 for controlling the light source 309.

[0144] In particular, the image generating apparatus 300 has a processor 370, which may include a digital mirror control unit 305 for controlling the digital mirror device 308 and a light source control unit 306 for controlling the light source 309.

[0145] On the other hand, the signal processing device 170 may have 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 310-330.

[0146] On the other hand, the signal processing device 170 can also perform operation control of the digital reflector device 308 or operation control of the light source 309 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.

[0147] For example, as the external illuminance Cso increases, the signal processing device 170 can control the signal frame by frame so that the luminance of the first projected image LTa output from the light output device 400 is smaller than the luminance of the second projected image LTb.

[0148] As another example, as the internal illuminance Csi decreases, the signal processing device 170 can control the signal frame by frame so that the luminance of the first projected image LTa output from the light output device 400 is smaller than that of the second projected image LTb.

[0149] As another example, as the setting input Csp decreases, the signal processing device 170 can control the signal frame by frame so that the brightness of the first projected image LTa output from the light output device 400 is smaller than the brightness of the second projected image LTb.

[0150] On the other hand, a vehicle display device 100 according to an embodiment of the present invention may further include a second actuator ACTc for adjusting the height or angle of the screen Scr.

[0151] For example, the signal processing device 170 can control the adjustment of the height of the screen Scr. Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously changing the height of the dashboard display.

[0152] On the other hand, a vehicle display device 100 according to an embodiment of the present invention may further include a third actuator ACTb for adjusting the height or angle of the second reflector 320.

[0153] For example, the signal processing device 170 can control the height or angle of the first reflector 310 or the second reflector 320 to be adjusted according to the height adjustment of the screen Scr. Thus, a plurality of displays can be integrated using a single image generation device 300, while simultaneously changing the height of the dashboard display.

[0154] Figures 6 to 14d Is Figure 5 The diagram referenced in the description.

[0155] Figure 6 Examples are shown as follows Figure 4b The first and second projected images are shown, and then as follows: Figure 4d The image shown is an example of the first projected image.

[0156] Refer to the attached diagram, as follows Figure 6 As shown in (a), in an embodiment of the present invention, the image generating apparatus 300 in the vehicle display device 100 outputs a first projected image LTa and a second projected image LTb.

[0157] At this time, the size of the first projected image LTa output from the image generating device 300 can be larger than the size of the second projected image LTb.

[0158] The first projected image LTa output from the image generating device 300 is reflected by a portion of the first reflector 310 SZa and projected onto one side of the screen Scr.

[0159] At this time, the size of the first projected image LTa projected onto the side of the screen Scr can correspond to the first size Arb in the vertical direction.

[0160] On the other hand, the second projected image LTb output from the image generating device 300 is reflected in a portion of the second reflector 320 and projected onto one side of the windshield WS.

[0161] At this time, the size of the second projected image LTb projected onto one side of the windshield WS can correspond to the second size Ara in the vertical direction.

[0162] according to Figure 6(a) The image generating apparatus 300 outputs the first projected image LTa in an upward direction than the second projected image LTb.

[0163] Moreover, according to Figure 6 (a) The height Ha of the lower end TEa of the first reflector 310 can be higher than the height of the lower end TEb of the second reflector 320.

[0164] On the other hand, the signal processing device 170 can control the lower end TEa of the first reflector 310 to be lowered when the height of the lower end TEa of the first reflector 310 is higher than the height of the lower end TEb of the second reflector 320, so as to increase the size of the first projected image LTa projected onto the screen Scr. Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously changing the size of the dashboard display.

[0165] Figure 6 Example (b) shows the first projected image LTa projected onto the screen Scr with the largest size.

[0166] Right now, Figure 6 Example (b) illustrates the case where the second projected image LTb projected onto one side of the windshield WS is not projected.

[0167] For example, as shown in the figure, the signal processing device 170 can control the height of the lower end TEa of the first reflector 310 to be reduced to Hb when the height of TEa is Ha.

[0168] On the other hand, the signal processing device 170 can be controlled to, in such a way, Figure 6 In the display mode shown in (a), the first projected image LTa is displayed on the screen Scr, and the second projected image LTb is projected and reflected onto the windshield WS, as shown in... Figure 6 In the instrument panel standalone display mode shown in (b), the first projected image LTa is displayed on the screen Scr, while the second projected image LTb is not projected onto the windshield WS. Thus, multiple displays can be integrated using a single image generating device 300, while simultaneously changing the size of the instrument panel displays.

[0169] On the other hand, with in such Figure 6 Compared to the size SZa of the area where the first projected image LTa is incident on the first reflector 310 in the complex display mode shown in (a), in such a way... Figure 6 In the instrument panel standalone display mode shown in (b), the size SZb of the area where the first projected image LTa is incident on the first reflector 310 can be larger.

[0170] That is, with Figure 6 Compared to (a), in Figure 6 In case (b), the size of the first projected image LTa output from the image generating device 300 becomes larger, thereby the size of the area incident on the first reflector 310 becomes larger, and as a result, the size of the first projected image LTa projected onto the screen Scr becomes larger.

[0171] At this point, the size of the first projected image LTa projected onto the side of the screen Scr can correspond to the fifth size Arb3 in the vertical direction. That is, the fifth size Arb3 can be larger than the first size Arb.

[0172] Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously changing the size of the dashboard display.

[0173] Figure 7 For example Figure 4b The first and second projected images are shown, and then as follows: Figure 4c This is an example of a smaller size for the first projected image.

[0174] Refer to the attached diagram, as follows Figure 7 As shown in (a), in an embodiment of the present invention, the image generating apparatus 300 in the vehicle display device 100 outputs a first projected image LTa and a second projected image LTb.

[0175] The first projected image LTa output from the image generating device 300 is reflected by a portion of the first reflector 310 SZa and projected onto one side of the screen Scr.

[0176] At this time, the size of the first projected image LTa projected onto the side of the screen Scr can correspond to the first size Arb in the vertical direction.

[0177] On the other hand, the second projected image LTb output from the image generating device 300 is reflected in a portion of the second reflector 320 and projected onto one side of the windshield WS.

[0178] At this time, the size of the second projected image LTb projected onto one side of the windshield WS can correspond to the second size Ara in the vertical direction.

[0179] according to Figure 7 (a) The image generating apparatus 300 can output the first projected image LTa in an upward direction than the second projected image LTb.

[0180] Moreover, according to Figure 7 (a) The height Ha of the lower end TEa of the first reflector 310 can be higher than the height of the lower end TEb of the second reflector 320.

[0181] On the other hand, the signal processing device 170 can control the height of the lower end TEa of the first reflector 310 to be increased when the height of the lower end TEa of the first reflector 310 is higher than the height of the lower end TEb of the second reflector 320, so as to reduce the size of the first projected image LTa projected onto the screen Scr. Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously changing the size of the dashboard display.

[0182] Figure 7 Example (b) illustrates that the size of the first projected image LTa projected onto the screen Scr is less than [the size of the first projected image LTa]. Figure 7 Case (a).

[0183] Right now, Figure 7 Examples of (b), such as Figure 4c As shown, the second projected image LTb projected onto one side of the windshield WS is larger than the size of the first projected image LTa projected onto the screen Scr.

[0184] For example, as shown in the figure, the signal processing device 170 can control the height of the lower end TEa of the first reflector 310 to be raised to Hc when the height of TEa is Ha.

[0185] On the other hand, with in such Figure 7 Compared to the size SZa of the area where the first projected image LTa is incident on the first reflector 310 in the complex display mode shown in (a), in such a way... Figure 7 In the complex display mode shown in (b), the size SZc of the area where the first projected image LTa is incident on the first reflector 310 can be smaller.

[0186] That is, with Figure 7 Compared to (a), in Figure 7 In case (b), the size of the first projected image LTa output from the image generating device 300 becomes smaller, thereby the size of the area incident on the first reflector 310 becomes smaller, and as a result, the size of the first projected image LTa projected onto the screen Scr becomes smaller.

[0187] At this point, the size of the first projected image LTa projected onto the side of the screen Scr can correspond to the third size Arb2 in the vertical direction. That is, the third size Arb2 can be smaller than the first size Arb.

[0188] Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously changing the size of the dashboard display.

[0189] On the other hand, with in such Figure 7Compared to the size of the area where the second projected image LTb is incident on the second reflector 320 in the complex display mode shown in (a), in such a way... Figure 7 In the complex display mode shown in (b), the size of the area where the second projected image LTb is incident on the second reflector 320 can be larger.

[0190] That is, with Figure 7 Compared to (a), in Figure 7 In case (b), the size of the second projected image LTb output from the image generating device 300 becomes larger, thereby the size of the area incident on the second reflector 320 becomes larger, and as a result, the size of the second projected image LTb projected onto the windshield WS becomes larger.

[0191] At this time, the size of the second projected image LTb projected onto one side of the windshield WS can correspond to the fourth size Ara2 in the vertical direction. That is, the fourth size Ara2 can be larger than the second size Ara.

[0192] Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously changing the size of the head-up display.

[0193] Figure 8 For example Figure 4b The first and second projected images are shown, and then as follows: Figure 4e The image shown is an example of the second projected image.

[0194] Refer to the attached diagram, as follows Figure 8 As shown in (a), in an embodiment of the present invention, the image generating apparatus 300 in the vehicle display device 100 outputs a first projected image LTa and a second projected image LTb.

[0195] At this time, the size of the first projected image LTa projected onto the side of the screen Scr can correspond to the first size Arb in the vertical direction, and the size of the second projected image LTb projected onto the side of the windshield WS can correspond to the second size Ara in the vertical direction.

[0196] according to Figure 8 (a) The image generating apparatus 300 outputs the first projected image LTa in an upward direction than the second projected image LTb.

[0197] Moreover, according to Figure 8 (a) The height Ha of the lower end TEa of the first reflector 310 can be higher than the height of the lower end TEb of the second reflector 320.

[0198] On the other hand, the signal processing device 170 can control the height of the lower end TEa of the first reflector 310 to be increased when the height of the lower end TEa of the first reflector 310 is higher than the height of the lower end TEb of the second reflector 320, so as to reduce the size of the first projected image LTa projected onto the screen Scr.

[0199] Figure 8 Example (b) shows that the first projected image is not projected onto the screen Scr, and the second projected image LTb, which is the largest, is projected onto one side of the windshield WS.

[0200] For example, as shown in the figure, the signal processing device 170 can control the height of the lower end TEa of the first reflector 310 to be raised to Hd when the height of TEa is Ha.

[0201] On the other hand, the signal processing device 170 can be controlled to, in such a way, Figure 8 In the display mode shown in (a), the first projected image LTa is displayed on the screen Scr, and the second projected image LTb is projected and reflected onto the windshield WS, as shown in... Figure 8 In the standalone head-up display mode shown in (b), the first projected image LTa is not projected onto the screen Scr, and the second projected image LTb is projected onto and reflected onto the windshield WS. Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously allowing the size of the head-up display to be changed.

[0202] On the other hand, it can be, and in such a way Figure 8 Compared to the size of the area where the second projected image LTb is incident on the second reflector 320 in the complex display mode shown in (a), in such a way... Figure 8 In the head-up display standalone display mode shown in (b), the area where the second projected image LTb is incident on the second reflector 320 is larger.

[0203] At this time, the size of the second projected image LTb projected onto one side of the windshield WS can correspond to the sixth size Ara4 in the vertical direction. That is, the sixth size Ara4 can be larger than the second size Ara.

[0204] Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously changing the size of the head-up display.

[0205] Figure 9 For example Figure 4b The image shown is an example of a first and second projected image, followed by a change in the screen height.

[0206] Refer to the attached diagram, as follows Figure 9As shown in (a), in an embodiment of the present invention, the image generating apparatus 300 in the vehicle display device 100 outputs a first projected image LTa and a second projected image LTb.

[0207] At this time, the size of the first projected image LTa projected onto the side of the screen Scr can correspond to the first size Arb in the vertical direction, and the size of the second projected image LTb projected onto the side of the windshield WS can correspond to the second size Ara in the vertical direction.

[0208] according to Figure 9 (a) The image generating apparatus 300 outputs the first projected image LTa in an upward direction than the second projected image LTb.

[0209] Moreover, according to Figure 9 (a) The height Ha of the lower end TEa of the first reflector 310 can be higher than the height of the lower end TEb of the second reflector 320.

[0210] On the other hand, the signal processing device 170 can control the height of the screen Scr.

[0211] For example, the signal processing device 170 can control a second actuator ACTc used to adjust the height or angle of the screen Scr.

[0212] Figure 9 Example (b) shows that, according to the action of the second actuator ACTc, the height of the screen Scr increases from the first height H1 to the second height H2.

[0213] On the other hand, the signal processing device 170 can control the first actuator ACTa to change the position or angle of the first reflector 310, or control the third actuator ACTb to adjust the height or angle of the second reflector 320 when the height of the screen Scr changes.

[0214] For example, the signal processing device 170 can control the screen Scr to maintain the size of the first projected image LTa projected onto the side of the screen Scr at a first size Arb in the vertical direction, and to maintain the size of the second projected image LTb at a second size Ara in the vertical direction when the height of the screen Scr is increased.

[0215] As illustrated in the attached figure, as the height of the screen Scr increases from the first height H1 to the second height H2, the position or angle of the first reflector 310 changes, thereby increasing the angle of incidence of the first projected image LTa incident on the first reflector 310, and the height or angle of the second reflector 310 changes, thereby decreasing the angle of incidence of the second projected image LTb incident on the second reflector 320.

[0216] This allows the size of both the instrument panel display and the head-up display to remain unchanged while setting the height of the instrument panel display for the driver.

[0217] Figure 10 For example Figure 4b The first and second projected images are shown, and then as follows: Figure 4d The image shown is another example that only displays the first projected image.

[0218] Although Figure 10 and Figure 6 Similar, but different in that the image generating device 300 outputs the first projected image LTa in a lower direction than the second projected image LTb.

[0219] Refer to the attached diagram, as follows Figure 10 As shown in (a), in an embodiment of the present invention, the image generating apparatus 300 in the vehicle display device 100 outputs a first projected image LTa and a second projected image LTb.

[0220] At this time, the size of the first projected image LTa projected onto the side of the screen Scr can correspond to the first size Arb in the vertical direction, and the size of the second projected image LTb projected onto the side of the windshield WS can correspond to the second size Ara in the vertical direction.

[0221] according to Figure 10 (a) The image generating apparatus 300 outputs the first projected image LTa in a direction that is lower than the second projected image LTb.

[0222] Moreover, according to Figure 10 (a) The height Hma of the lower end TEa of the first reflector 310 can be lower than the height of the lower end TEb of the second reflector 320.

[0223] On the other hand, the signal processing device 170 can control the height of the lower end TEa of the first reflector 310 to be increased when the height of the lower end TEa of the first reflector 310 is lower than the height of the lower end TEb of the second reflector 320, so as to increase the size of the first projected image LTa projected onto the screen Scr. Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously changing the size of the dashboard display.

[0224] Figure 10 Example (b) shows that the size of the first projected image LTa projected onto the screen Scr is the largest.

[0225] Right now, Figure 10 Example (b) illustrates the case where the second projected image LTb projected onto one side of the windshield WS is not projected.

[0226] For example, as shown in the figure, the signal processing device 170 can control the height of the lower end TEa of the first reflector 310 to be increased to Hmb when the height of TEa is Hma.

[0227] On the other hand, the signal processing device 170 can be controlled to, in such a way, Figure 10 In the display mode shown in (a), the first projected image LTa is displayed on the screen Scr, and the second projected image LTb is projected and reflected onto the windshield WS, as shown in... Figure 10 In the instrument panel standalone display mode shown in (b), the first projected image LTa is displayed on the screen Scr, while the second projected image LTb is not projected onto the windshield WS. Thus, multiple displays can be integrated using a single image generating device 300, while simultaneously changing the size of the instrument panel displays.

[0228] On the other hand, with in such Figure 10 Compared to the size SZa of the area where the first projected image LTa is incident on the first reflector 310 in the complex display mode shown in (a), in such a way... Figure 10 In the instrument panel standalone display mode shown in (b), the size SZb of the area where the first projected image LTa is incident on the first reflector 310 can be larger.

[0229] That is, with Figure 10 Compared to (a), in Figure 10 In case (b), the size of the first projected image LTa output from the image generating device 300 becomes larger, thereby the size of the area incident on the first reflector 310 becomes larger, and as a result, the size of the first projected image LTa projected onto the screen Scr becomes larger.

[0230] At this point, the size of the first projected image LTa projected onto the side of the screen Scr can correspond to the fifth size Arb3 in the vertical direction. That is, the fifth size Arb3 can be larger than the first size Arb.

[0231] Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously changing the size of the dashboard display.

[0232] Figure 11 For example Figure 4b The first and second projected images are shown, and then as follows: Figure 4c Another example of a smaller size in the first projected image shown.

[0233] Refer to the attached diagram, as follows Figure 11 As shown in (a), in an embodiment of the present invention, the image generating apparatus 300 in the vehicle display device 100 outputs a first projected image LTa and a second projected image LTb.

[0234] At this time, the size of the first projected image LTa projected onto the side of the screen Scr can correspond to the first size Arb in the vertical direction, and the size of the second projected image LTb projected onto the side of the windshield WS can correspond to the second size Ara in the vertical direction.

[0235] according to Figure 11 (a) The image generating apparatus 300 outputs the first projected image LTa in a direction that is lower than the second projected image LTb.

[0236] Moreover, according to Figure 11 (a) The height Hma of the lower end TEa of the first reflector 310 can be higher than the height of the lower end TEb of the second reflector 320.

[0237] On the other hand, the signal processing device 170 can control the lower end TEa of the first reflector 310 to be lowered when the height of the lower end TEa of the first reflector 310 is lower than the height of the lower end TEb of the second reflector 320, so as to reduce the size of the first projected image LTa projected onto the screen Scr. Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously changing the size of the dashboard display.

[0238] Figure 11 Example (b) illustrates the size ratio of the first projected image LTa projected onto the screen Scr. Figure 11 (a) small.

[0239] Right now, Figure 11 Example (b) is similar to... Figure 4c The size of the first projected image LTa projected onto the screen Scr is larger than the size of the second projected image LTb projected onto one side of the windshield WS.

[0240] For example, as shown in the figure, the signal processing device 170 can control the height of the lower end TEa of the first reflector 310 to be reduced to Hmc when the height of TEa is Hma.

[0241] On the other hand, with in such Figure 11 Compared to the size SZa of the area where the first projected image LTa is incident on the first reflector 310 in the complex display mode shown in (a), in such a way... Figure 11 In the complex display mode shown in (b), the size SZc of the area where the first projected image LTa is incident on the first reflector 310 can be smaller.

[0242] That is, with Figure 11 Compared to (a), in Figure 11In case (b), the size of the first projected image LTa output from the image generating device 300 becomes smaller, thereby the size of the area incident on the first reflector 310 becomes smaller, and as a result, the size of the first projected image LTa projected onto the screen Scr becomes smaller.

[0243] At this point, the size of the first projected image LTa projected onto the side of the screen Scr can correspond to the third size Arb2 in the vertical direction. That is, the third size Arb2 can be smaller than the first size Arb.

[0244] Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously changing the size of the dashboard display.

[0245] On the other hand, with in such Figure 11 Compared to the size of the area where the second projected image LTb is incident on the second reflector 320 in the complex display mode shown in (a), in such a way... Figure 11 In the complex display mode shown in (b), the size of the area where the second projected image LTb is incident on the second reflector 320 can be larger.

[0246] That is, with Figure 11 Compared to (a), in Figure 11 In case (b), the size of the second projected image LTb output from the image generating device 300 becomes larger, thereby the size of the area incident on the second reflector 320 becomes larger, and as a result, the size of the second projected image LTb projected onto the windshield WS becomes larger.

[0247] At this time, the size of the second projected image LTb projected onto one side of the windshield WS can correspond to the fourth size Ara2 in the vertical direction. That is, the fourth size Ara2 can be larger than the second size Ara.

[0248] Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously changing the size of the head-up display.

[0249] Figure 12 For example Figure 4b The first and second projected images are shown, and then as follows: Figure 4e The image shown is another example that only displays the second projected image.

[0250] Refer to the attached diagram, as follows Figure 12 As shown in (a), in an embodiment of the present invention, the image generating apparatus 300 in the vehicle display device 100 outputs a first projected image LTa and a second projected image LTb.

[0251] At this time, the size of the first projected image LTa projected onto the side of the screen Scr can correspond to the first size Arb in the vertical direction, and the size of the second projected image LTb projected onto the side of the windshield WS can correspond to the second size Ara in the vertical direction.

[0252] according to Figure 12 (a) The image generating apparatus 300 outputs the first projected image LTa in a direction that is lower than the second projected image LTb.

[0253] Moreover, according to Figure 12 (a) The height Hma of the lower end TEa of the first reflector 310 can be higher than the height of the lower end TEb of the second reflector 320.

[0254] On the other hand, the signal processing device 170 can control the lower end TEa of the first reflector 310 to be lowered when the height of the lower end TEa of the first reflector 310 is lower than the height of the lower end TEb of the second reflector 320, so as to reduce the size of the first projected image LTa projected onto the screen Scr.

[0255] Figure 12 Example (b) illustrates the case where the first projected image is not projected onto the screen Scr, and the size of the second projected image LTb is the largest, projected onto one side of the windshield WS.

[0256] For example, as shown in the figure, the signal processing device 170 can control the height of the lower end TEa of the first reflector 310 to be reduced to Hmd when the height of TEa is Hma.

[0257] On the other hand, the signal processing device 170 can be controlled to, in such a way, Figure 12 In the display mode shown in (a), the first projected image LTa is displayed on the screen Scr, and the second projected image LTb is projected and reflected onto the windshield WS, as shown in... Figure 12 In the standalone head-up display mode shown in (b), the first projected image LTa is not projected onto the screen Scr, and the second projected image LTb is projected onto and reflected onto the windshield WS. Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously allowing the size of the head-up display to be changed.

[0258] On the other hand, with in such Figure 12 Compared to the size of the area where the second projected image LTb is incident on the second reflector 320 in the complex display mode shown in (a), in such a way... Figure 12 In the head-up display standalone display mode shown in (b), the size of the area where the second projected image LTb is incident on the second reflector 320 can be larger.

[0259] At this time, the size of the second projected image LTb projected onto one side of the windshield WS can correspond to the sixth size Ara4 in the vertical direction. That is, the sixth size Ara4 can be larger than the second size Ara.

[0260] Thus, multiple displays can be integrated using a single image generation device 300, while simultaneously changing the size of the head-up display.

[0261] Figure 13 For example Figure 4b The image shown is another example of a situation where the height of the screen changes, displaying the first and second projected images.

[0262] Refer to the attached diagram, as follows Figure 13 As shown in (a), in an embodiment of the present invention, the image generating apparatus 300 in the vehicle display device 100 outputs a first projected image LTa and a second projected image LTb.

[0263] At this time, the size of the first projected image LTa projected onto the side of the screen Scr can correspond to the first size Arb in the vertical direction, and the size of the second projected image LTb projected onto the side of the windshield WS can correspond to the second size Ara in the vertical direction.

[0264] according to Figure 13 (a) The image generating apparatus 300 outputs the first projected image LTa in a direction that is lower than the second projected image LTb.

[0265] Moreover, according to Figure 13 (a) The height Hma of the lower end TEa of the first reflector 310 can be lower than the height of the lower end TEb of the second reflector 320.

[0266] On the other hand, the signal processing device 170 can control the height of the screen Scr.

[0267] For example, the signal processing device 170 can control a second actuator ACTc used to adjust the height or angle of the screen Scr.

[0268] Figure 13 Example (b) illustrates the case where the height of the screen Scr increases from the third height H3 to the fourth height H4 as the second actuator ACTc is activated.

[0269] On the other hand, when the height of the screen Scr changes, the signal processing device 170 can control the first actuator ACTa to change the position or angle of the first reflector 310, or control the third actuator ACTb to adjust the height or angle of the second reflector 320.

[0270] For example, the signal processing device 170 can control the first projection image LTa of the first projection image LTa to maintain a first size Arb when the height of the screen Scr is increased, and the second projection image LTb to maintain a second size Ara in the vertical direction.

[0271] The accompanying diagram illustrates how the position or angle of the first reflector 310 changes as the height of the screen Scr increases from a first height H1 to a second height H2.

[0272] This allows the size of both the instrument panel display and the head-up display to remain unchanged while setting the height of the instrument panel display for the driver.

[0273] Figures 14a to 14d Is Figure 5 The diagram referenced in the description.

[0274] Figure 14a and Figure 4b Correspondingly, an example is given where the first display 180a is a first-size Arb, and the third display 180h is a second-size Ara, which is smaller than the first-size Arb.

[0275] Referring to the accompanying drawings, a first projected image 810 of a first size Arb can be displayed on a first display 180a, which serves as an instrument panel display, and a second projected image 820 of a second size Ara can be displayed on a third display 180h, which serves as a head-up display.

[0276] Figure 14b and Figure 4c Correspondingly, an example is given where the first display 180a is a third-size Arb2, and the third display 180h is a fourth-size Ara2, which is larger than the third-size Arb2.

[0277] Referring to the accompanying drawings, a first projected image 810b of the third size Arb2 can be displayed on a first display 180a, which serves as an instrument panel display, and a second projected image 820b of the fourth size Ara2 can be displayed on a third display 180h, which serves as a head-up display.

[0278] Figure 14c and Figure 4d Correspondingly, the first display 180a is a fifth size Arb3, and there is no projected image projected onto the windshield WS, which serves as the third display 180h.

[0279] Referring to the attached figures, the first projection image 810c of the fifth size Arb3 is displayed in the first display 180a, which serves as an instrument panel display, while the third display 180h, which serves as a head-up display, does not display a projection image.

[0280] Figure 14dand Figure 4e Correspondingly, an example is shown where there is no projected image in the first display 180a, and the third display 180h is a larger sixth-size Ara4.

[0281] Referring to the attached diagram, the first display 180a, which serves as an instrument panel display, does not display a projected image, while the third display 180h, which serves as a head-up display, can display a second projected image 820d of size Ara4.

[0282] On the other hand, another embodiment of the present invention provides a vehicle display device 100 comprising: an image generating apparatus 300 including a light output device 400 for outputting a projected image; a first reflector 310 for reflecting a first projected image LTa, which is a part of the projected image from the image generating apparatus 300; a screen Scr on which the first projected image LTa reflected by the first reflector 310 is projected onto one side; a second reflector 320 for reflecting a second projected image LTb, which is another part of the projected image from the image generating apparatus 300, onto a windshield WS; and a first actuator ACTa for changing the position or angle of the first reflector 310, thereby changing the size of the first projected image LTa projected onto the screen Scr or the size of the second projected image LTb reflected onto the windshield WS based on the change in the position or angle of the first reflector 310. Thus, a plurality of displays can be integrated using a single image generating apparatus 300, while simultaneously changing the size of the dashboard display or head-up display.

[0283] On the other hand, another embodiment of the vehicle display device 100 of the present invention further includes a signal processing device 170 for controlling the first actuator ACTa. The signal processing device 170 is capable of controlling the size of the first projected image LTa projected onto the screen Scr or the size of the second projected image LTb reflected onto the windshield WS to change based on a change in the position or angle of the first reflector 310. Thus, a plurality of displays can be integrated using a single image generation device 300, while simultaneously changing the size of the instrument panel display or head-up display.

[0284] On the other hand, the signal processing device 170 can control the size of the first projected image LTa projected onto the screen Scr or the size of the second projected image LTb reflected onto the windshield WS by changing the height of the lower end TEa of the first reflector 310.
