Embodiment Construction

[0019] Please refer to figure 1 , figure 1 It is a schematic cross-sectional structure diagram of the electronic device 10 according to the first embodiment of the present invention. The electronic device 10 may be an electronic device with a touch display function, such as a mobile phone, a computer, a game console, and a television. The electronic device 10 includes a touch module 100 and a housing 116 for fixing the touch module 100 inside.

[0020] The touch module 100 includes a display unit 110 and a pressure sensor 150 . In this embodiment, the display unit 110 is an external touch display unit, and the display unit 110 includes a cover plate 111 , a touch panel 112 , a display panel 113 and a backlight element 114 that are stacked in sequence. The display panel 113 and the backlight element 114 can be fixed by, for example, a plastic frame (not shown). The cover plate 111 is covered above the touch panel 112 and can be supported on the plastic frame. The cover pla...

Abstract

The invention discloses a touch module. The touch module comprises a display unit and at least one pressure sensor, wherein the display unit comprises a display surface facing a user; the at least one pressure sensor is arranged on one side, far away from the display surface, of the display unit; each pressure sensor comprises a signal sending layer which is used for sending ultrasonic wave signals and a signal reception layer which is used for receiving the ultrasonic wave signals; the signal sending layer and the signal reception layer are opposite to each other; and the distance between the signal sending layer and the signal reception layer changes along with the change of touch pressure applied on the display surface by the user. The invention furthermore provides a method for sending touch pressure suffered by touch interfaces by utilizing the pressure sensor and an electronic device with the touch module.

Description

technical field [0001] The present invention relates to a touch module, a touch pressure sensing method based on the touch module, and an electronic device having the touch module. Background technique [0002] In recent years, touch panels as input devices of electronic products have been widely used in touch electronic products such as mobile phones, computers, game consoles, and televisions. Among them, ultrasonic sensors are less affected by the state of the touch object (such as the cleanliness of fingers) and can obtain more accurate sensing results, and are widely used in touch electronic products to realize the touch function. However, this type of ultrasonic sensor is mainly used to determine the touch position, but does not have the function of sensing the touch force, which is not conducive to developing the application of ultrasonic sensors to realize the diversity of touch functions. SUMMARY OF THE INVENTION [0003] In view of the above, it is necessary to p...
