• Subjects: DEVICES OR ARRANGEMENTS, THE OPTICAL OPERATION OF WHICH ISMODIFIED BY CHANGING THE OPTICAL PROPERTIES OF THE MEDIUM OF THEDEVICES OR ARRANGEMENTS FOR THE CONTROL OF THE INTENSITY,COLOUR, PHASE, POLARISATION OR DIRECTION OF LIGHT, e.g.SWITCHING, GATING, MODULATING OR DEMODULATING; FREQUENCY-CHANGING; NON-LINEAR OPTICS; OPTICAL ANALOGUE/DIGITAL CONVERTERS; OPTICAL LOGIC ELEMENTS; OPTICS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF

Display apparatuses are disclosed. In one arrangement, a display apparatus comprises an optically opaque layer and one or more stacks of additional layers provided on the optically opaque layer. Each stack comprises an optically switchable layer. A plurality of switching elements are located on a side of the optically opaque layer opposite to the one or more stacks. Each switching element is operable to apply a signal, for example an electrical signal or a thermal signal, through the optically opaque layer to a switchable portion of the optically switchable layer, thereby changing an appearance of the switchable portion when viewed from a viewing side of the display apparatus. The surface area of the optically opaque layer on the viewing side is at least 10% larger than the total surface area of the switchable portions on the viewing side. 本发明公开了一种显示设备。在一种布置中，显示装置包括光学不透明层和设置在该光学不透明层上的附加层的一个或多个叠组。每个叠组包括光学可切换层。多个切换元件位于光学不透明层的与一个或多个叠组相对的这一侧。每个切换元件可操作通过光学不透明层施加信号(例如电信号或热信号)到光学可切换层的可切换部分，从而当从显示装置的观看侧观看时，改变可切换部分的外观
