Embodiment Construction

[0063] The embodiments of the present invention will be further explained by following relevant drawings. As far as possible, in the drawings and description, the same reference numerals represent the same or similar components. In the drawings, the shape and thickness may be exaggerated for simplicity and convenience. It can be understood that the elements not particularly shown in the drawings or described in the specification are in the form known to those skilled in the art. Those skilled in the art can make various changes and modifications based on the content of the present invention.

[0064] See below image 3 Firstly, the first embodiment of the present invention will be introduced. The capacitive pressure-sensitive display device of the present invention includes a pressure-sensitive display device 48 and a pressure-sensitive device 50. The pressure-sensitive device 50 is disposed at the bottom of the pressure-sensitive display device 48 to establish a plurality of ...

Abstract

The invention discloses a capacitive pressure-sensitive display apparatus. The apparatus comprises a pressure-sensitive display apparatus and a pressure-sensitive apparatus. The pressure-sensitive apparatus is arranged at the bottom of the pressure-sensitive display apparatus; multiple first capacitors are established in the pressure-sensitive display apparatus; and multiple second capacitors are established in the pressure-sensitive apparatus. When an external pressure is applied to the pressure-sensitive display apparatus, the pressure-sensitive display apparatus changes the first capacitors to detect the external pressure; and when all the first capacitors stop change, the pressure-sensitive display apparatus applies a pressure to the pressure-sensitive apparatus by utilizing the external pressure to change the second capacitors and detect the external pressure. According to the apparatus, at least two-stage type capacitors are formed to detect an excessively large pressure, and the pressure-sensitive apparatus is arranged at the bottom of the pressure-sensitive display apparatus to avoid the influence of related factors of a mechanism on the running effect of the pressure-sensitive apparatus.

Description

Technical field [0001] The present invention relates to a display device, and more particularly to a capacitive pressure-sensitive display device. Background technique [0002] In the current consumer electronics market, portable electronic products such as personal digital assistants (PDAs), mobile phones, car touch screen devices and notebooks have been widely used in portable electronic products. The touch panel serves as an interface tool for data communication between the user and the electronic device. There are many types of common touch technologies, such as resistive, capacitive, or optical touch, etc., which can be touched by a finger or an electromagnetic pen to determine the touch position to perform corresponding functions. However, touch technology must not only be able to control and operate the functions of the product, it is also the main trend in the development of current touch technology for applications such as writing or drawing or playing games. [0003] In...
