Mobile terminal provided with organic electroluminescent and liquid crystal devices
View Patent ↗The invention provides an electronic apparatus that provides an organic electroluminescent device and a liquid crystal device. In a mobile terminal electronic apparatus, such as an electronic apparatus having a device that displays, and in particular, a mobile telephone that has power consumption restrictions, includes an organic electroluminescent device, which provides fine display having superior visibility, and a transflective or reflective liquid crystal display device, which severely reduces power consumption, and thereby achieves low power consumption while not in use, and allows selective use of displays depending on the type of information, such as video or still images, and the condition of the remaining battery charge, or the like.
1. A mobile terminal comprising:
an organic electroluminescent device to display images;
a liquid crystal device to display images, the mobile terminal being capable of being folded such that the organic electroluminescent device faces inside while the liquid crystal device faces outside, said liquid crystal device being a transflective liquid crystal display device; and
a battery provided in said mobile terminal and a device that suspends displaying images by said organic electroluminescent device and that switches automatically to displaying images by said liquid crystal device, when a remaining charge of the battery provided in said mobile terminal becomes a predetermined remaining charge.
2. The mobile terminal according to claim 1 , when not manipulated for a predetermined period or during stand-by, said organic electroluminescent device being in a non-display mode, and only said liquid crystal device being in a display mode.
3. The mobile terminal according to claim 1 , said organic electroluminescent device being driven by an active matrix driving method.
4. The mobile terminal according to claim 1 , said liquid crystal device being driven by a simple matrix driving method.
5. The mobile terminal according to claim 1 , said liquid crystal device being driven by an active matrix driving method.
6. The mobile terminal according to claim 1 , said liquid crystal device being a monochrome display.
7. The mobile terminal according to claim 1 , said liquid crystal device being a color display.
8. The mobile terminal according to claim 1 , further comprising a device that switches display between said liquid crystal device and said organic electroluminescent device.
9. The mobile terminal according to claim 1 , further comprising a device that switches display from said organic electroluminescent device to said liquid crystal device when said organic electroluminescent display is not manipulated for a predetermined period while said organic electroluminescent display is continuously driven.
10. The mobile terminal according to claim 1 , the organic electroluminescent device including red, green and blue light emitting organic electroluminescent elements.
11. The mobile terminal according to claim 1 , the organic electroluminescent display automatically turned OFF when the mobile terminal is folded from the opened state.
12. The mobile terminal according to claim 1 , the organic electroluminescent device automatically turned ON when mobile terminal is opened from the folded state.
