Power Sequencing

Some LCD flat panel displays can be damaged if the voltage and data signals are applied at power up. This can result in damage to the panel or reduction of its operational life. The LB P6d module provides the control signals for switching the power supply lines to protect the flat panel. Power to the panel must be enabled using the special enable signals provided on the flat panel connector, ENAVEE, ENAVDD, and ENABKL.

Advanced Power Management

The same signals that support power sequencing are also used to provide the power management feature. In “panel off mode” both the CRT and flat panel interfaces are turned off, but the VGA subsystem (registers and display memory) remain powered. In “standby mode”, the CRT and flat panel interfaces are turned off, and in addition, the VGA subsystem is turned off. The screen DRAM is placed in a low-power mode in which only the DRAM is refreshed.
