Abstract
According to a display control method in accordance with the present invention, in a case where an image to be displayed changes in tone between two successive frames, (i) a first dimming process for changing a luminance of a backlight and a second dimming process for changing a level of a tone distribution setting are carried out in a plurality of frame periods in accordance with tones obtained before and after the change, and (ii) at least a second dimming period containing a start timing and a processing time of the second dimming process is controlled in accordance with a temperature of a liquid crystal display panel.
Claims13
A display control method for changing, in accordance with a characteristic of an image to be displayed in a liquid crystal display panel, (i) a luminance of a backlight which emits light to the liquid crystal display panel and (ii) a tone distribution of the image to be displayed in the liquid crystal display panel,
- said display control method including:
- a first dimming process for, in order to change first image data of a first frame to second image data of a second frame following the first frame, changing, in a backlight luminance change time which is a plurality of frame periods, a first backlight luminance corresponding to the first image data to a second backlight luminance corresponding to the second image data;
- and
- a second dimming process for changing, in a tone distribution change time which is a plurality of frame periods, a first tone distribution setting corresponding to the first image data to a second tone distribution setting corresponding to the second image data,
- said display control method comprising the step of:
- controlling, in accordance with a temperature of the liquid crystal display panel, at least the second dimming period which contains a start timing and a processing time of the second dimming process.
A display control apparatus which changes, in accordance with a characteristic of an image to be displayed in a liquid crystal display panel, (i) a luminance of a backlight which emits light to the liquid crystal display panel and (ii) a tone distribution of the image to be displayed in the liquid crystal display panel,
- said display control apparatus comprising:
- a first dimming process section which controls the luminance of the backlight by carrying out a first dimming process for, in order to change first image data of a first frame to second image data of a second frame following the first frame, changing, in a luminance change time which is a plurality of frame periods, a first luminance corresponding to the first image data to a second luminance corresponding to the second image data;
- and
- a second dimming process section which controls a tone distribution setting of the liquid crystal display panel by carrying out a second dimming process for changing, in a tone distribution change time which is a plurality of frame periods, a first tone distribution setting corresponding to the first image data to a second tone distribution setting corresponding to the second image data,
- at least the second dimming process section controlling, in accordance with a temperature of the liquid crystal display panel, a second dimming period containing a start timing and a processing time of the second dimming process, the temperature having been obtained via a temperature measuring section which directly or indirectly measures a temperature of the liquid crystal display panel.
