Display assembly

Abstract

The invention concerns a display assembly comprising an organic light-emitting diode display device comprising at least one OLED (1) comprising an emitting stack structure placed on a transparent, semi-transparent or translucent substrate (2), whose back face is placed on the emitting surface of the OLED (1), and a secondary object to be illuminated, said transparent substrate comprising a front face and at least one side face (8) arranged to light a secondary object (6). The invention further relates to a watch including the display assembly.

Description

technical field [0001] The present invention relates to a display assembly and more particularly to an organic light emitting diode (OLED) display assembly intended to illuminate a passive display device, eg in a timepiece such as a wristwatch. Background technique [0002] In the watch industry, more and more devices combine traditional mechanical displays using hands with digital displays, for example for applications related to smartphones or to any other object provided with communication mechanisms. [0003] In such devices, when the digital display is a backlit display, it is turned on only when needed to reduce the power consumption of the system, however, mechanical display devices are purely passive and therefore cannot operate without Type-coated cases are read in the dark. These phosphorescent coatings do not function well enough in certain applications (for example for date discs), not only because of the small surface area applied, but also because of the exce...

Problems solved by technology

[0007] However, for date, no matter what the extraction means, a non-negligible proportion of the light emitted at the junction of the LED remains trapped and lost within the light guide formed by the substrate and, in due course, in the different layers that make up the OLED
