 <description><![CDATA[I am using micro2440 SDK.

As for the voltage, the same board works with 800x480 LCD (AT070TN83) which has similar specs.

 <description><![CDATA[I think this issue may be cuased by either incorrect voltage supply of LCD on hardware or incorrect LCD parameters settings on software.
It should be a 3.3V voltage supply&nbsp;&nbsp;for LCD panel and 5V for backlight according to the datasheet?]]></description>
