Luminous density distribution producing method for LCD-display, involves detecting and recording luminous density distribution of white picture, and detecting compensation picture from minimum luminous density and recorded distribution

摘要

The method involves detecting and recording a luminous density distribution of a white picture, which is represented on a LCD-display (6) by a picture recording device (9). A minimum luminous density is determined from the recorded distribution. A compensation picture is detected from the determined minimum density and the recorded distribution. The compensation picture is applied on a compensation foil (8). An independent claim is also included for an LCD display module.
