LIQUID CRYSTAL DISPLAY DEVICE |
摘要 |
PROBLEM TO BE SOLVED: To provide a liquid crystal display device for suppressing image quality deterioration of display images even when in-plane temperature distribution of a liquid crystal display panel is formed. SOLUTION: The liquid crystal display device for displaying images by using the liquid crystal display panel 4 comprises: temperature sensors 16a-16d for detecting temperatures in a plurality of regions A-D of the liquid crystal display panel 4, respectively; a control CPU 17 for generating a switching control signal on the basis of frequency distribution of detected temperatures in the liquid crystal display panel 4; and an emphasis conversion part 22 for finding an emphasis conversion signal compensating optical response characteristics of the liquid crystal display panel by performing emphasis conversion of an input image signal in response to combination of a switching control signal generated by the control CPU 17 and gradation transition before and after one vertical period of the input image signal.
