Problems solved by technology

However, at this stage, products with touch panels only have touch functions, but the force of the touch cannot be known. If you need to confirm the pressure of the touch, you need to use it with an electromagnetic stylus.
[0004] Moreover, if the pressed state of the touch point, such as the pressed size, cannot be detected, more functional features of the electronic product will not be provided.

Embodiment Construction

[0026] See figure 2 and image 3 , figure 2 Shown is a schematic diagram of a first embodiment of a touch display device according to the present invention; image 3 shown along figure 2 Schematic cross-sectional view of line AA. The present invention provides a touch display device 100. The touch display device 100 includes a touch panel 101, a display module 102, and at least one pressure sensing unit 103. The touch panel 101 has a sensing area 104 and is located in the sensing area. The peripheral area 105 outside the area 104, in addition, the touch panel 101 also includes a cover plate disposed on its upper part to protect the surface of the touch panel 101, and the cover plate can be a transparent glass substrate or film, for example. The display module 102 includes a display panel 106 and a frame body 107 , and the frame body 107 is used for accommodating the display panel 106 . The display module 102 is, for example, a liquid crystal display module. In additio...

Abstract

The invention discloses a touch display device. The touch display device comprises a touch panel, a display module and at least one pressure sensing unit, wherein the touch panel is provided with a sensing area and a peripheral area; the display module comprises a display panel and a frame body; the display panel can be accommodated in the frame body; each pressure sensing unit comprises a first electrode, a second electrode and an elastic insulator; the first electrodes are arranged on the peripheral area of the touch panel; the second electrodes are arranged on the frame body; the elastic insulators are arranged between the touch panel and the display module; each elastic insulator is positioned between the corresponding first electrode and the corresponding second electrode; and a pushing force, which is inputted to the touch panel, of a user is determined by the touch display device according to the variable quantity of a capacitance between each first electrode and the corresponding second electrode. Under the condition that an electromagnetic stylus or another pressure sensor is not used, touch pressure can be detected with the aid of the variable quantity of the capacitances of the pressure sensing units of the peripheral area and is quantified.

Description

technical field [0001] The present invention relates to a touch display device, in particular to a touch display device capable of detecting the magnitude of touch pressure. Background technique [0002] In recent years, with the rapid development and application of information technology, wireless mobile communications and information home appliances, many information products such as mobile phones, notebook computers, MP4 and various automatic The service terminal has changed from the traditional input device such as keyboard or mouse to the use of touch panel as the input device, among which the touch display panel is the most popular product nowadays. Existing touch panels can be roughly classified into capacitive, resistive, and photosensitive types, among which resistive and capacitive touch panels are the mainstream products. However, no matter what kind of touch panel, the accuracy of its finger sensing is the focus of design. [0003] See figure 1 , figure 1 Sho...
