  FIG. 1 is a block diagram showing a hardware configuration of a graphic meter 100 which is a display device for a vehicle in the embodiment. The graphic meter 100 includes a CPU 110, a graphic CPU 130, a liquid crystal display 150, and a memory (EEPROM) 117.

  The CPU 110 includes a ROM 112, a RAM 113, and a network unit (CAN) 115. The ROM 112 stores a control program to be described later. The RAM 113 is used as a work area.

  The network unit 115 communicates with other devices via the communication I / F 124 in accordance with the CAN (Controller Area Network) standard, and inputs information such as speed, engine speed, fuel amount, shift position, and the like. Further, the network unit 115 inputs information on the steering switch 140 connected to the communication I / F 124 as another device.

  A signal of an ignition switch (IGN +) is input to the CPU 110 via an input interface (I / F) 122. The CPU 110 is connected to a power supply circuit 121 that is supplied with power from the battery (+ B) and outputs a power supply voltage Vcc and a reset voltage. The CPU 110 is connected to an ODO / TRIP switch 126 that switches between the display of the travel distance and the accumulated travel distance.

  The graphic CPU 130 displays graphic elements on the screen of the liquid crystal display 150 in accordance with a command input from the CPU 110. The graphic CPU 130 is connected to a ROM 132 that stores 3D graphic drawing software and a RAM 133 that is a frame memory that holds display contents for each pixel.

  In practice, the CPU 110 writes display data to the RAM 133, and the graphic CPU 130 executes 3D graphic drawing software based on the display data written to the RAM 133 to generate an opening screen, an icon selection screen, and the like, which will be described later. The rendered image data is given to the liquid crystal display 150 to perform graphic drawing. Further, the graphic CPU 130 generates a vertical synchronization signal and a horizontal synchronization signal for two-dimensionally scanning the screen of the liquid crystal display 150. The image data is given to the liquid crystal display 150 at a timing synchronized with these synchronization signals.

  The liquid crystal display 150 (display unit) has a color two-dimensional display screen (graphic display screen) in which a large number of minute display cells configured by a liquid crystal device are arranged in the X direction and the Y direction. The liquid crystal display 150 graphically displays various types of information such as figures, characters, and images on the two-dimensional display screen by individually controlling the display state of a large number of micro display cells for each cell.
