Touch panel, touch detection method thereof and display device with touch function

Abstract

The invention discloses a touch panel, which is suitable for detecting the touch position of a touch point. The touch panel comprises a substrate and at least one first direction detection device. The first direction detection device is arranged in the first direction of the substrate to detect first direction coordinates of the touch point. Each first direction detection device comprises a first deformation induction device and a second deformation induction device. The first deformation induction device produces deformation in the first direction due to the production of the touch point, and provides a first variable due to the deformation; the second deformation induction device produces deformation in the first direction due to the production of the touch point, and provides a second variable due to the deformation; and the first direction coordinates are decided by the first variable and the second variable. The invention discloses a touch monitoring method for the touch panel and a display device with touch function at the same time.

Description

technical field [0001] The present invention relates to the field of touch detection, and in particular to a touch panel, a touch detection method thereof, and a display device with a touch function. Background technique [0002] With the advancement of technology, flat panel display devices (such as liquid crystal display devices) are widely used in mobile phones, notebook computers, desktops, etc. Consumer electronic products such as display devices and televisions have gradually replaced traditional cathode ray tube display devices and become the mainstream of display devices. [0003] The touch panel provides a new human-computer interaction interface, which is more intuitive and humane in use. Integrating the touch panel into the flat display device can replace the traditional input device, making it more direct and more humane. However, the existing technology for integrating a touch panel into a flat-panel display device is generally to directly attach the touch pan...

Problems solved by technology

However, the existing technology for integrating a touch panel into a flat-panel display device is generally to directly attach the touch panel to the flat-panel display device, and the sensing element used in the existing touch panel is composed of multiple layers of materials. Therefore, the thickness of the entire touch panel cannot be effectively reduced, and jointly, the thickness of the entire flat-panel display device cannot be effectively reduced.

Moreover, the touch panel also reduces the light transmittance and other optical performances of the flat-panel display device, thereby affecting the visual effect of the flat-panel display device.

[0004] In addition, most of the existing touch panels need to use planar printing technology or coating technology to install sensing elements with multi-layer materials on the entire touch panel, so it is difficult for manufacturers without planar printing or coating technology to enter the touch panel. control detection field
