摘要: A scanning backlight unit (BU) for a matrix display comprises plurality of light sources (L1, ...,Ln). driver (2) supplies drive signals (D1, ...,Dn) to the controller (3) controls separately activate ...,Ln) obtain light-emitting regions (5) being active. sensor (4) is associated with group at least two supply signal (SES) which indicates luminance (LU) group. The reads different instants (ts1, ..., tsn) mutually subsets are active control power levels (LU1, ...,LUn) each one in dependence on (SES).
