Indicator device with a barrier discharge lamp for backlighting

A display device with a locally controllable brightness filter as a display screen, and

• a discharge lamp for backlighting with
• a bottom plate,
• a top plate for the light exit which is at least partially transparent,
• a discharge space between the bottom and the top plate for accommodating a discharge medium,
• a set of electrodes for generating dielectrically impeded discharges in the discharge medium, and
• a dielectric barrier between at least one part of the set of electrodes and the discharge medium,
• the set of electrodes being split into spatially separated groups that can be driven separately from one another,
• the brightness filter having linewise driven pixels and the electrode groups forming strips parallel to the pixel lines,
• characterized in that the display device is designed to operate the electrode groups synchronously with the driving of the pixels for the purpose of reinputting brightness image information into the corresponding lines at a brighter level than in the remaining operational phases.
