Abstract
A method and an apparatus for operating an LED display are provided. The method includes: storing Nth scan line data in a line buffer; storing the Nth scan line data in a frame buffer; displaying the Nth scan line data stored in the line buffer; during the displaying of the Nth scan line data stored in the line buffer, storing (N+1)th scan line data in the line buffer; storing the (N+1)th scan line data in the frame buffer; displaying the (N+1)th scan line data stored in the line buffer; repeating the above steps until (N+M)th scan line data stored in the line buffer is displayed; and displaying scan line data stored in the frame buffer from the Nth scan line data to the (N+M)th scan line data.
Claims20
A method for operating an LED display, comprising:
- storing a Nth scan line data in at least one line buffer, wherein N is a natural number equal or more than one;
- displaying the Nth scan line data stored in the at least one line buffer;
- during the displaying of the Nth scan line data stored in the at least one line buffer, storing the Nth scan line data in at least one frame buffer, and storing a (N+1)th scan line data in the at least one line buffer;
- displaying the (N+1)th scan line data stored in the at least one line buffer;
- during the displaying of the (N+1)th scan line data stored in the at least one line buffer, storing the (N+1)th scan line data in the at least one frame buffer, and storing a (N+2) th scan line data in the at least one line buffer;
- displaying the (N+2)th scan line data stored in the at least one line buffer;
- and
- during the displaying of the (N+2)th scan line data stored in the at least one line buffer, storing the (N+2)th scan line data in the at least one frame buffer.
An apparatus for operating an LED display, comprising:
- at least one line buffer;
- at least one frame buffer;
- and
- at least one processor and at least one memory device communicatively coupled to the at least one processor, and the at least one memory device stores instructions operable when executed by the at least one processor to perform the steps of:
- storing a Nth scan line data in at least one line buffer, wherein N is a natural number equal or more than one;
- displaying the Nth scan line data stored in the at least one line buffer;
- during the displaying of the Nth scan line data stored in the at least one line buffer, storing the Nth scan line data in at least one frame buffer, and storing a (N+1)th scan line data in the at least one line buffer;
- displaying the (N+1)th scan line data stored in the at least one line buffer;
- during the displaying of the (N+1)th scan line data stored in the at least one line buffer, storing the (N+1)th scan line data in the at least one frame buffer, and storing a (N+2)th scan line data in the at least one line buffer;
- displaying the (N+2)th scan line data stored in the at least one line buffer;
- and
- during the displaying of the (N+2)th scan line data stored in the at least one line buffer, storing the (N+2)th scan line data in the at least one frame buffer.
