<P>PROBLEM TO BE SOLVED: To provide a display device, a display controller and a display device adjustment method for achieving a stable white balance over a signal brightness area, and also, achieving a well-balanced matching of RGB gradation properties and brightness signal gradation properties. <P>SOLUTION: A display properties adjustment circuit 20 comprises: a gamma properties adjustment block 21, a switch block 22, a gain adjustment block 23 and a bias adjustment block 24. The gamma properties adjustment block 21 is separately provided with a Y-axis property table and a C-axis property table related to respective RGB signals. In the switch block 22, when respective RGB input values of the RGB signals are equal, the C-axis property table is used, on the other hand, when respective RGB input values are not equal, the Y-axis property table is used. In the Y-axis property table, the gamma properties having the brightness coincident with the brightness of the C-axis property table, and also, having fixed chromaticity is set. <P>COPYRIGHT: (C)2009,JPO&INPIT |
