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 in particular to a capacitive pressure-sensitive display device. Background technique [0002] In today's various consumer electronics markets, portable electronic products such as personal digital assistants (PDAs), mobile phones (mobile phones), automotive touch screen devices, and notebook computers (notebooks) have been widely used. The touch panel is used as an interface tool for data communication between the user and the electronic device. And there are many kinds of common touch technologies, such as resistive, capacitive or optical touch, which can judge the touch position by the touch of a finger or an electromagnetic pen, so as to execute corresponding functions. However, touch technology not only needs to be able to control and operate the functions of products, but also the application of writing or drawing or playing games is the main trend of the current development of touch technol...
