INFORMATION PROCESSOR, DISPLAY CONTROL METHOD OF LIQUID CRYSTAL DISPLAY DEVICE, PROGRAM FOR EXECUTING THE DISPLAY CONTROL METHOD, AND INFORMATION PROCESSOR IN WHICH ADJUSTMENT EFFECT OF VIEWING ANGLE WIDTH IS IMPROVED

摘要

PROBLEM TO BE SOLVED: To provide an information processor in which adjusting effect of a viewing angle width is improved by controlling gradation of a liquid crystal display (LCD) device, a display control method, and a program for executing the display control method with which a viewing angle characteristic is controlled. SOLUTION: The information processor includes second software for forwarding display control of the LCD panel from a CPU 12 to first software after receiving a display mode change instruction, and a plurality of display control table 38 in which color pallet data of less than 128 gradation levels are allocated with degeneration for a higher gradation level. From an identification data of the LCD panel which is acquired by the first or the second software to which the control is forwarded, a degeneration color conversion table corresponding to the identification data is retrieved. A display adapter 30 reads out the degeneration color conversion table retrieved from a display control table storing section 36 to a look-up-table (LUT) reading section 40 and generates an RGB signal in which the gradation is degenerated.
