METHOD OF ADJUSTING AN ACOUSTIC OUTPUT FROM A DISPLAY DEVICE

摘要

A display device arranged generates a visual and an acoustic output according to an input signal (AVS) with audio (AS) and video (VS) content. The display device includes a cabinet (C) with different mounting fittings (MS, MW) arranged for different types of mounting of the display device. A display (FPD), an acoustic system including one or more loudspeakers (L), a mounting detector (SW), e.g. a microswitch, arranged to detect a type of mounting of the display device, and compensation means (AF) arranged to modify the acoustic output from the display device according to the detected type of mounting of the display device. Hereby, it is possible to adjust the frequency content of the acoustic output from the acoustic system, e.g. electronically, to correspond to the acoustic environment determined by means of sensing the type of mounting of the display device. E.g. one microswitch can be used to discriminate between wall or stand mounting, and digital coefficients for an IIR or an FIR filter can be selected accordingly to compensate the acoustic output from the display device to a desired response. Hereby sound performance of especially flat panel display devices can be improved, since such devices typically exhibit an audio performance which is highly depending on the type of mounting due.
