Embodiment Construction

[0029] exist figure 1 The display operating panel 10 according to the first embodiment of the invention can be seen in the figure. The display operation area 10 has an operation panel 12 , a first light source 14 , a second light source 16 and a detector 18 . The first light source 14 has a light emitting element 15 and the second light source 16 has a light emitting element 17 . The two light-emitting elements 15 , 17 are designed in the form of light-emitting diodes.

[0030] The operating panel 12 is formed in the shape of a plate and has an operating surface 20 and a rear surface 22 , which faces the light sources 14 , 16 . The operating surface 20 is intended to be contacted by an object or an operator's finger in order to perform machine operations. In the embodiment shown, the operating panel 12 is partially transparent, since it is transparent in the window region 24 above the light sources 14 , 16 and is formed opaque in the mask region 26 . exist figure 1 An ope...

Abstract

The display operating panel (10) has an at least partially light-transmissive operating panel (12), a plurality of light sources (14, 16, 42) and at least one detector (16, 18), wherein the operating panel (12) has an operating surface (20), said at least one detector (14, 16, 18, 42) detects light emitted by said light sources (14, 16, 42) when the operating surface (20) is touched, these light sources (14, 16,42) emit light that is modulated in a way that is not directly perceptible to the human eye, where the light from these sources (14,16,42) is personalized by encoding such that light from adjacent sources (14,16,42) When overlapping, it is possible to determine which light source emits light (14,16,42).

Description

technical field [0001] The invention relates to a display operating panel with an at least partially light-transmissive operating panel, a plurality of light sources and at least one detector, wherein the operating panel has an operating surface, and the at least one detector detects when the operating surface is touched. The light source emits light that is modulated in such a way that the human eye cannot directly perceive it. The invention also relates to a domestic appliance with such a display operating panel and a method for operating such a display operating panel. Background technique [0002] The term "display operating panel" refers to a display unit which has a plurality of display elements and operating elements beneath a common surface. The touch-sensitive display operating panel has proven to be robust, since it requires no moving mechanical components. It has proven to be particularly advantageous if the operating element is arranged spatially close to the d...
