Detailed Shorted-LED Error Report
The detailed shorted-LED error report can be read out immediately after global error mode has been run (see Global
Error Mode on page 11) . SDI must be 1 for the first device.

Detailed Shorted-LED Error Report Example
Consider a case where three AS1113s are cascaded in one chain. A 1 indicates a LED is on, a 0 indicates a LED is off,
and an X indicates a shorted LED. This test is used on-the-fly.
IC1:[11111XX111111111] IC2:[1111111111111111] IC3:[X100011111111111]
IC1 has two shorted LEDs which are switched on, IC3 has one shorted LED switched off due to input. 3*16 clock
cycles are needed to write the entire error code out. The detailed error report would look like this:
Input Data: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
LED Status: 1 1 1 1 1 X X 1 1 1 1 1 1 1 1 1
Failure Code: 1 1 1 1 1 0 0 1 1 1 1 1 1 1 1 1

X1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
1111111111111111
Showing IC1 as the device with two shorted LEDs at position 6 and 7, and IC3 with one shorted LED at position 1. The
shorted LED at position 1 of IC3 cannot be detected, since LEDs turned off at test time are not tested and will show a
logic "1" at the detailed error report. To test all LEDs this test should be run with an all 1s test pattern. For a test with an
all on test pattern, low-current diagnostic mode should be entered first to reduce on-screen flickering.
Note: In an actual report there are no spaces in the output. LEDs turned off during test time cannot be tested and will
show a logic 1 in the detailed error report.
Low-Current Diagnostic Mode
To run the open- or shorted-LED test, a test pattern must be used that will turn on each LED to be tested. This test pat-
tern will cause a short flicker on the screen while the test is being performed. The low-current diagnostic mode can be
initiated prior to running a detailed error report to reduce this on-screen flickering.
Note: Normally, displays using such a diagnostic mode require additional cables, resistors, and other components to
reduce the current. The AS1113 has this current-reduction capability built-in, thereby minimizing the number of
external components required.
Low-current diagnostic mode can be initiated via 3 clock pulses during error-detection mode. After the falling edge of
LD, a test pattern displaying all 1s can be written to the shift register which will be used for the next error-detection test.
