PTN3460显示问题

[zhoulonghua]

PTN3460的自检画面应该是怎样的？在将“TESTMODE”拉高后显示白画面是为什么呢？是否有相关的文档说明。

Hi,

Please see attached the AN15228 for PTN3460 self-test screen function.

If the TESTMODE pin is raising high, then configuration pins (CFG1-4) will be disabled (no functioning), so it may cause no display (white display) on LCD panel.

BR, Tomas
