Functional description

2.7

Brightness adjustment (8 bits)

Brightness adjustment is controlled by Register 2 (I2C table 1). It consists of adding the same DC

voltage (BRT) to the three RGB signals. This DC voltage can be adjusted between 0 and 2V, outside

the blanking pulse with 8mV adjustment steps (see

Figure 7).

Inside the blanking pulse the DC output level is forced to the “Infra Black” level (Vib).
