Abstract
An LED display panel including a plurality of LEDs arranged in a matrix, a plurality of lighting data lines connecting the LEDs in either one of a row direction and a column direction, and a plurality of scanning lines connecting the LEDs in the other one of the row direction and the column direction. At least either the lighting data lines or the scanning lines connect the LEDs such that the lighting data lines or the scanning lines form groups of at least two lines crossing in a staggered configuration.

The LED display apparatus comprising:
- a display panel having a plurality of LEDs arranged in a matrix and a plurality of lighting data lines and scanning lines for driving the LEDs, the lighting data lines connecting the LEDs linearly in either one of a row direction and a column direction, and the scanning lines connecting the LEDs in the other one of the row direction and the column direction such that the lighting data lines or the scanning lines form groups of at least two lighting data lines or scanning lines crossing in a staggered configuration;
- a lighting data drive circuit having a plurality of lighting data output terminals for transmitting lighting data to the lighting data lines of the LED display panel which are connected to the lighting data output terminals;
- a scanning drive circuit having a plurality of scanning output terminals for sequentially scanning the scanning lines of the LED display panel which are connected to the scanning output terminals;
- a decoder which receives address data about a scanning sequence and transmits to the scanning drive circuit a signal for sequentially scanning the scanning output terminals of the scanning drive circuit according to the received address data;
- an encoder to which the scanning lines are connected;
- and
- a comparator for comparing the address data input to the decoder with output data from the encoder.
