Abstract
An image display device includes: a first display panel and a second display panel in which transmittance or reflectance of light is controlled on the basis of an image signal; and a light irradiation unit that irradiates the first display panel and the second display panel with light, wherein the first display panel and the second display panel are sequentially driven by image signals corresponding to a plurality of color light beams, and in a period in which one of the first display panel and the second display panel is driven by an image signal corresponding to any one of the plurality of color light beams, an image signal for driving the other display panel is switched.
Claims12
An image display device, comprising:
- a light irradiation unit;
- a first display panel configured to obtain a first image;
- a second display panel configured to obtain a second image;
- and
- a control circuit configured to:
- control the light irradiation unit to irradiate the first display panel with first light and the second display panel with second light;
- control one of transmittance of the first light or reflectance of the first light based on a first image signal of a plurality of image signals;
- control one of transmittance of the second light or reflectance of the second light based on a second image signal of the plurality of image signals, wherein
- the second image signal is different from the first image signal, and
- the plurality of image signals corresponds to a plurality of color light beams;
- drive, in a first period, the first display panel based on the first image signal;
- drive, in the first period, the second display panel based on the second image signal and a third image signal of the plurality of image signals, wherein
- the third image signal is different from the second image signal, and
- the first display panel and the second display panel are configured to be sequentially driven;
- and
- control, in a second period, the light irradiation unit to stop the irradiation of the second display panel, wherein
- the second image signal is switched to the third image signal in the second period, and
- the first period includes the second period.
An electronic apparatus provided with an image display device, comprising:
- an image display device comprising:
- a light irradiation unit;
- a first display panel configured to obtain a first image;
- a second display panel configured to obtain a second image;
- and
- a control circuit configured to:
- control the light irradiation unit to irradiate the first display panel with first light and the second display panel with second light;
- control one of transmittance of the first light or reflectance of the first light based on a first image signal of a plurality of image signals;
- control one of transmittance of the second light or reflectance of the second light based on a second image signal of the plurality of image signals, wherein
- the second image signal is different from the first image signal, and
- the plurality of image signals corresponds to a plurality of color light beams;
- drive, in a first period, the first display panel based on the first image signal;
- drive, in the first period, the second display panel based on by the second image signal and a third image signal of the plurality of image signals, wherein
- the third image signal is different from the second image signal, and
- the first display panel and the second display panel are configured to be sequentially driven;
- and
- control, in a second period, the light irradiation unit to stop the irradiation of the second display panel, wherein
- the second image signal is switched to the third image signal in the second period, and
- the first period includes the second period.
