Abstract
An electronic apparatus using a liquid crystal display device, a display control method used in the liquid crystal display device, and a non-transitory recording medium for storing a display control program, sets a region having a larger area of an information display region and a background region as a transmission region and a region having a smaller area as a shielding region in an illumination mode. A tint change of the shielding region caused by a TN type liquid crystal and a light source for backlight is reduced, and thus, it is possible to make the tint change depending on the viewing direction unremarkable.
Claims12
A liquid crystal display device comprising:
- a semi-transmission type liquid crystal display panel using a twisted nematic (TN) type liquid crystal;
- a backlight unit that is set in an illumination mode in which backlight including light rays of two or more wavelength ranges is illuminated or a non-illumination mode in which the backlight is not illuminated;
- and
- a display controller that displays information on the liquid crystal display panel by setting one of a shielding region which shields the backlight and an external incidence ray and a transmission region which transmits the backlight and the external incidence ray as an information display region and setting the other one as a background region,
- wherein the display controller performs first display control in which a region having a larger area of the information display region and the background region is set as the shielding region and a region having a smaller area is set as the transmission region in the non-illumination mode, and performs second display control in which the region having the larger area of the information display region and the background region is set as the transmission region and the region having the smaller area is set as the shielding region in the illumination mode.
A display control method of a liquid crystal display device comprising a semi-transmission type liquid crystal display panel using a TN type liquid crystal, and a backlight unit that is set in an illumination mode in which backlight including light rays of two or more wavelength ranges is illuminated or a non-illumination mode in which the backlight is not illuminated, the method comprising:
- a display control step of displaying information on the liquid crystal display panel by setting one of a shielding region which shields the backlight and an external incidence ray and a transmission region which transmits the backlight and the external incidence ray as an information display region and setting the other one as a background region,
- wherein the display control step performs first display control in which a region having a larger area of the information display region and the background region is set as the shielding region and a region having a smaller area is set as the transmission region in the non-illumination mode, and performs second display control in which the region having the larger area of the information display region and the background region is set as the transmission region and the region having the smaller area is set as the shielding region in the illumination mode.
