Table 3-56 describes the return parameters.
Parameter Bytes | Description |
---|---|
Byte 1 | Maximum LED power (LSByte) |
Byte 2 | Maximum LED power (MSByte) |
The value is specified in watts × 100 (for example: 25.75W = A0Fh). This command is only applicable when CAIC is enabled.
The CAIC maximum available LED power pertains if an all-white image is displayed where LED currents are set by the Write RGB LED Current command. The calculation is:
R duty cycle × R LED current × R LED voltage +
G duty cycle × G LED current × G LED voltage +
B duty cycle × B LED current × B LED voltage.
For example: (.30 × .49A × 2.0V) + (.50 × .39A × 3.1V) + (.20 × .39A × 3.1V) = (.30 × .980W) + (.50 × 1.209W) + (.20 × 1.209W) = 1.140W
