  Here, a driving principle of a TN (Twisted Nematic) type liquid crystal as an example of the liquid crystal will be described with reference to FIGS. 10 and 11. In the TN type liquid crystal, light does not pass as shown in FIG. When a twisted liquid crystal is sandwiched between two polarizing filters Fa and Fb (polarizing plates) whose polarization directions are orthogonal to each other, light entering from above is twisted 90 degrees along the gap between the liquid crystal molecules. Can pass through Fb. As shown in FIG. 10 (b), when a voltage is applied to the liquid crystal, the liquid crystal molecules stand upright and become twisted, and light entering from above is directed downward, so that it cannot pass through the lower filter Fb. That is, as shown in FIG. 11, light is transmitted when no voltage is applied to the liquid crystal molecules, and when the voltage is applied, the light is blocked and becomes black on the screen. The liquid crystal functions as a light shutter by the voltage. Fulfill. For this reason, the brightness can be controlled by controlling the voltage applied to the liquid crystal.

Further, the control unit (display control means) 20 determines the D seat image and the P seat image for the operation input from the operation target of the operation button group 152 and the touch panel 130 according to the mode state. Thereby, an ideal image can be displayed according to the operation input. Details will be described below.

Next, an example of a process of determining the D seat image and the P seat image for the operation input according to the mode state by the control unit 20 will be described with reference to FIG. This process is repeatedly executed during the operation of the in-vehicle display device.
FIG. 13 is a flowchart illustrating an example of processing for determining the D seat image and the P seat image for the operation input according to the mode state by the control unit 20.
Based on the signal from the operation button group 152 or the touch panel 130, the control unit 20 determines whether or not an operation is performed on the in-vehicle display device (step ST1). If the operation is not performed, this process is performed. finish.
When the operation is performed, the control unit 20 determines whether the seat mode is the D seat mode based on the signal from the switching button 151 (step ST2). When the operation mode is the D seat mode, the control unit 20 operates the driver seat screen. The D seat image corresponding to the input is displayed (step ST3). As a result, the driver can operate the driver seat image.
For example, as shown in FIG. 14A, in the state where a TV image is displayed as a P seat image and a navigation image is displayed as a D seat image, when the D seat mode is selected, the driver By operating the operation button group 152 or the touch panel 130, the D seat image corresponding to the operation input is displayed on the driver seat screen.

(Step ST22) When there is no operation, this process is terminated.
When an operation is performed on the in-vehicle display device, the control unit 20 determines whether the seat mode is the D seat mode (step ST23). If the seat mode is the D seat mode, the control unit 20 performs the process of step ST3 in FIG.
When not in the D-seat mode, that is, in the P-seat mode, the control unit 20 displays a restriction image that prohibits the operation on the driver seat screen (step ST24). With such a configuration, it is possible to prevent the driver from operating the driver's seat screen during traveling and to prevent a reduction in driving attention. The restriction image is a still image or a single color image.
For example, as shown in FIG. 16A while the vehicle is traveling, the P seat mode is selected and the passenger seat is selected in the state where the TV image is displayed as the P seat image and the navigation image is displayed as the D seat image. When the passengers perform the operation, as shown in FIGS. 16B and 16C, the P seat image corresponding to the operation input is displayed on the passenger seat screen. However, a restriction image is displayed on the driver seat screen.
Further, the control unit 20 displays a P seat image corresponding to the operation input on the passenger seat screen (step ST25). Thus, even when the vehicle is traveling, when an operation is performed in the P seat mode, an image permitting the operation is displayed on the passenger seat screen. With such a configuration, the passenger in the passenger seat can operate the passenger seat image even during traveling. Note that when displaying a driver's seat screen for which operation input has been made in the D-seat mode while traveling, functions that are complicated to operate and images that may cause the screen to be watched (for example, TV images, DVD images, characters) It is assumed that no input operation or image display is performed on the input screen.

Next, an example of processing of the control unit 20 in the case of on-screen display will be described with reference to FIG.
FIG. 17 is a flowchart illustrating an example of processing performed by the control unit 20 when performing on-screen display. This process is repeatedly executed during the operation of the in-vehicle display device.
Based on the signal from the operation button group 152 or the touch panel 130, the control unit 20 determines whether or not an operation is performed on the in-vehicle display device (step ST31). If the operation is not performed, this process is performed. finish.
When the operation is performed, the control unit 20 determines whether or not the operation input needs to display a predetermined image on the driver seat screen and the passenger seat screen on-screen (step ST32). In the case of an operation input that does not need to be displayed on the screen, the control unit 20 executes the processing from step ST2 of the flowchart of FIG.
In the case of an operation input that needs to be displayed on the screen, the control unit 20 displays a predetermined image on the screen for the driver seat and the screen for the passenger seat (step ST33). With such a configuration, it is possible to grasp what operation the other party has performed.
For example, as shown in FIG. 16A while the vehicle is traveling, the P seat mode is selected and the passenger seat is selected in the state where the TV image is displayed as the P seat image and the navigation image is displayed as the D seat image. When a passenger who needs to perform an on-screen display operation performs an on-screen display on the driver's seat screen as shown in FIG. 16D.
