Flat panel display
View Patent ↗The present invention is directed to a flat panel display device and a method for driving thereof. According to the present invention, in the flat panel display for processing and displaying a display signal outputted from the graphic source via a serial bus, the graphic source fetches and interprets the display characteristics information of the flat panel display from the flat panel display module via the serial bus so that a new corresponding standard of display signal can be outputted. Here, the display characteristics information is adjustable by the input of predetermined data by use of a predetermined key installed outside the flat panel display by a user and includes more than one of standard information of the display signal with its blanking interval defined and screen display information. A flat panel display according to an embodiment of the present invention is essentially comprised of a graphic source including a graphic source unit; and a liquid crystal display module including a connector, a D/A converter, a memory, and a timing controller.
1. A flat panel display for processing and displaying a display signal corresponding to display characteristics information outputted from a graphic source unit to the flat panel display via a serial bus, the graphic source unit being installed in an apparatus for generating and outputting the display signal including graphic signals and control signals, the display comprising:
a serial bus;
a timing controller directly connected to the serial bus for receiving the display signal outputted from the graphic source unit via the serial bus;
a memory, directly connected to the serial bus for connection to both the graphic source unit and the timing controller, for storing the display characteristics information adapted to the flat panel display; and
a Digital-Analog converter, directly connected to the serial bus for connection to both the timing controller and the graphic source unit, for converting a plurality of digital gamma values based on the display characteristics information into a plurality of analog gamma values,
wherein the timing controller outputs the digital gamma values to the Digital-Analog converter.
2. The flat panel display of claim 1 , wherein the memory is a non-volatile memory.
3. The flat panel display of claim 2 , wherein the memory is a EEPROM.
4. The flat panel display of claim 1 , wherein the display characteristics information includes resolution information, frequency information, and gamma information.
5. The flat panel display of claim 1 , wherein the timing controller produces a display data based on the display characteristics information and the display signal and outputs the display data to a row driver.
6. A method for driving a flat panel display for processing and displaying a display signal corresponding to display characteristics information outputted from a graphic source unit to the flat panel display via a serial bus, the graphic source unit being installed in an apparatus for generating and outputting the display signal including graphic signals and control signals, the method comprising:
receiving the display signal outputted from the graphic source unit via the serial bus;
storing the display characteristics information adapted to the flat panel display;
producing a display data based on the display characteristics information and the display signal and outputting the display data to a row driver; and
receiving digital gamma values and converting the digital gamma values into analog gamma values.
