Digital instrument display method of vehicle and apparatus thereof

A digital instrument display apparatus of a vehicle to display data generated by each sensor unit of the vehicle on a vehicle instrument panel, comprising:

• a CPU (100) that runs an application module, copies size and position of a bitmap font image that matches an acquired character string from an external storage memory, and controls to display on an instrument display unit using a graphic engine module and a graphic library or controls to display image information received from a content module on an instrument panel;
• the application module (200) that runs the graphic engine module, receives signals from each sensor unit, analyzes received information to generate external event data with information identifiers and types (values), and stores the external event data in an internal memory (RAM, EEPROM);
• the graphic engine module (300) that runs the content module, receives a character string from the content module, acquires position and size information of a bitmap font image that matches the character string from a font table stored in the external storage memory, and receives corresponding image information stored previously from the content module;
• the content module (400) that receives the external event data stored in the internal memory for every frame and determines whether the external event data is a character string, transmits corresponding character string information to the graphic engine module if the external event data is the character string, and transmits corresponding image address information stored previously to the graphic engine module if the external event data is not the character string;
• the graphic library (500) that stores screen components provided by a microcontroller unit (MCU) manufacturer;
• the external storage memory (600) that stores the bitmap font image and the font table for fonts to be used;
• each sensor unit (700) that generates sensor information and transmits the sensor information to the application module;
• the instrument panel (800) that displays the bitmap font image or displays an image according to control of a control unit;
• a timer (900) that provides time information to the CPU;
• a serial interface (950) that provides an interface between the CPU and the external storage memory;
• and
• an I/O (970) for external data input and output,
• wherein the content module comprises Stage, Layer, Sprite, Shape, and TextField to display the character string.
