LED display apparatus |
摘要 |
An LED display apparatus includes a first LED display including a first LED, a second LED display including a second LED, and a luminance corrector. The luminance corrector corrects a luminance of the first LED in accordance with a first cumulative lighting period of the first LED and with both luminance transitions and a second cumulative lighting period of the second LED. |

1. An LED display apparatus comprising:
a first LED display including a first LED; a second LED display including a second LED that undergoes luminance transitions equivalent to luminance transitions of said first LED; a lighting period storage to store a first cumulative lighting period of said first LED; a luminance meter to measure a luminance of said second LED; a luminance transition storage to correlate and store said luminance transitions of said second LED measured by said luminance meter and a second cumulative lighting period of said second LED; and a luminance corrector to correct a luminance of said first LED in accordance with said first cumulative lighting period stored in said lighting period storage and with said luminance transitions and said second cumulative lighting period of said second LED both stored in said luminance transition storage. |
