Abstract: A backlight unit of a display apparatus includes a power converter generating a light source power voltage in response to a power control signal, a first node, a second node, a light emitting element connected between the first node and the second node, and a controller connected to the second node. The light emitting element is configured to receive the light source power voltage through the first node, and the controller is configured to output the power control signal for controlling current flowing through the light emitting element in response to a dimming signal. When the dimming signal has a first level, the controller outputs the power control signal to turn off the power converter.

Abstract: A digital exposure device including a GLV or a DMD. The digital exposure device also includes: a stage to support and move a substrate in a scan direction; an optical system disposed between the stage and the GLV or the DMD, to form a pattern on the substrate by modulating light received from the GLV or the DMD; and a control unit to control the a width of the pattern by a unit, the unit being obtained by dividing the width of the pattern by a natural number m, in the second direction.
