Problems solved by technology

However, these high-quality emissive display devices do not allow reflective mode of operation
As a result, the information displayed is very accessible in dim or dark conditions, but becomes difficult to read when viewed outdoors

Embodiment Construction

[0020] The present invention starts from the general inventive concept. The inventive concept of the present invention is to provide a display assembly that can display information in a readable manner during daytime or dusk or darkness, and has the best power consumption. In order to achieve this object, the present invention provides a teaching of combining an emissive display device with a display device arranged to be switchable between a resting state and an active state, the display device being transparent in the resting state and in the active state Able to reflect ambient light. The emissive display device is typically an organic light emitting diode display unit, and the reflective display device is typically a liquid crystal display unit. In order to display information during the day, it is preferable to use a reflective display device, which reflects sunlight and can display information in a clear and readable manner with low power consumption. In order to display...

Abstract

The invention relates to a hybrid display assembly including a solar cell. The display assembly (1) for a portable object includes a first, at least partially transparent, emissive display device (2) located on the side of an observer, a second reflective display device (6) and a solar cell (10) being arranged, in that order, underneath the first emissive display device (2). The second reflective display device (6) is capable of switching between a transparent state, in which the device does not display any information, and a reflective state, when activated.

Description

Technical field [0001] The present invention relates to a hybrid display module including solar cells. More specifically, the present invention relates to a display assembly that includes two superimposed display devices, and solar cells are arranged under the two superimposed display devices. Background technique [0002] The readability of the information displayed by a display device such as a liquid crystal display unit or an organic light emitting diode display device is very dependent on the ambient lighting conditions. With some display devices, the displayed information can be read in a good state in an illuminated environment, but it is difficult to read in a dark environment. In contrast, other types of display devices provide a good quality display at dusk or in the dark, but are difficult to read during the day. [0003] By way of example, let us consider a transflective liquid crystal display unit, that is, a liquid crystal display unit that can display information. ...
