Table 3-63 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: 25.75 W = 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: (0.30 × 0.49A × 2.0V) + (0.50 × 0.39A × 3.1V) + (0.20 × 0.39 A × 3.1V) = (0.30 × 0.980W) + (0.50 × 1.209W) + (0.20 × 1.209W) = 1.140W
