Benefits of technology

This new technology has its benefits that are explained below for better understanding by referring to specific examples or figures drawn up on this figure-making process.

Problems solved by technology

This patent describes various technical features related to improving the functionality and usability of touch screens found in vehicles and consumer electronics products. One key issue addressed is how to ensure reliable operation despite environmental factors such as rainwater immersion, dust protection, temperature variations, etc., especially under conditions where visibility becomes poor. Additionally, the use of auditory displays made up of multiple layers allows users to experience both visual and audio experiences simultaneously.

[0197] also available in Figure 12 The side opposite to the operating surface of the tactile presentation panel 100 shown is configured as Figure 36 The touch panel shown in segmented construction. Even in this case, configure the Figure 36 The detection electrodes and excitation electrodes in the region of A can be as Figure 37 , 38 shape. In addition, the shapes of the detection electrodes and the excitation electrodes are not limited to Figure 37 , 38 It is only necessary to have a structure in which the mutual capacitance in the same region is larger than the mutual capacitance with the electrodes between the regions of the detection electrode and the excitation electrode that are different in adjacent structures. Specifically, the distance between the detection electrode and the excitation electrode in the same region may be narrower than that between the detection electrode or the excitation electrode in different regions. As a result, the influence of the capac

Abstract

The purpose of the present invention is to provide a tactile sensation presentation panel, a tactile sensation presentation touch panel, a tactile sensation presentation touch display, and a tactile sensation presentation knob capable of imparting an appropriate tactile sensation to a user. A haptic presentation panel according to the present invention is provided with: a haptic presentation voltage generation circuit (113) that generates a voltage signal having a first frequency that is applied to at least one first electrode (102a) located in at least a partial region of an operation surface of the haptic presentation panel; a voltage signal generating unit (102) that generates a voltage signal having a second frequency different from the first frequency and applied to at least one second electrode (102b) located in at least a partial region of the operation surface of the tactile presentation panel; a charge discharge unit (115) that is connected to the tactile electrode and discharges the charge accumulated in the conductive elastic unit (6); and a touch detection circuit (210) that detects that a user touches the tactile presentation knob (3).
