Figure 5. Data Format.
Self-Test Mode
The display incorporates a self-test mode composed of a 1x2 checkerboard pattern that inverts every few seconds. The self-test mode is entered by applying power to the display with the S signal static. The display remains in this mode until two (2) low-to-high transitions of the S signal are detected. The display then enters and remains in normal (user video driven) operation as long as power is applied. To enter self-test mode again, the display must be reset by cycling the VH power input.
