Problems solved by technology

The disadvantage here is that an air gap necessarily exists between the input surface and the electro-optic display, so that undesired interfering reflections occur due to the transition from the input surface to the air gap and from the air gap to the electro-optic display.

Embodiment Construction

[0020] figure 1 An embodiment of a touch screen 100 according to the invention can be seen in the figure, which has: an input surface 101, an electro-optic display 102, an adhesive 103, a light conductor 104, a light source 105 in the form of a light-emitting diode, a cooling body 106, two motors 107 , two connecting pieces 108 , a bracket 109 in the form of a housing, two seals 110 , two connecting elements 111 and an air gap 112 . Furthermore, a part of the user's finger F (not shown) and the double-headed arrow A of the touchscreen according to the invention can be seen. The input surface 101 is connected to the electro-optic display 102 by means of an adhesive 103 . The bonding can in particular be implemented in the form of an optical bond. The light guide 104 is rigidly connected to the bracket 109 via the connecting element 111 , and likewise the light source 105 is rigidly connected to the bracket 109 via the heat sink 106 . Light from the light source 105 is couple...

Abstract

The invention relates to a touchscreen (100) having a haptic feedback device (107, 108), comprising an electro-optical display (102) with an input surface (101) arranged in front of said electro-optical display, and a carrier (109), wherein said electro-optical display (102) is connected mechanically and rigidly to the input surface (101), and said input surface (101) is designed to move relativeto the carrier (109) by means of a motor (107), wherein the electro-optical display (102) can be illuminated by an illumination device (105, 104) and said illumination device (105, 104) comprises a light source (105) which is connected immovably to the carrier (109).

Description

technical field [0001] The present invention relates to a touch screen with a tactile feedback device. Background technique [0002] Such touch screens are known from the prior art, which have an electro-optic display and a carrier, in front of which an input surface is arranged. In this case, the electro-optical display is connected mechanically rigidly to the input surface and is designed to be movable by a motor relative to the carrier. Liquid crystal displays or other transmissive displays can be used, for example, as electro-optic displays. Through the movement of the input surface, tactile feedback is produced for the user of the input surface touching the input surface. The movement of the input face can take place, for example, in a direction perpendicular or parallel to the surface of the input face. However, a combination of the above two movements is also possible. Typically, the path of movement of the input face relative to the carriage is less than 1 mm, up...
