Abstract

The invention discloses an electronic device with a function of double-side touch. The electronic device comprises a double-side display, a first light guide plate, a second light guide plate and a controller; the first light guide plate is arranged on one side of the double-side display; the second light guide plate is arranged on the other side of the double-side display; a light source is arranged between the first light guide plate and the double-side display; a receiver is arranged between the second light guide plate and the double-side display; the controller generates a transmitting control command and a receiving control command; the transmitting control command is used for controlling the light source to emit light to the display face of the double-side display; the receiving control command is used for controlling the receiver to receive light transmitted by the light source.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, and more specifically, relates to an electronic equipment capable of double-sided touch. Background technique [0002] In recent years, electronic devices supporting double-sided touch have been widely used. [0003] In the prior art, electronic equipment with double-sided touch includes two capacitive screens, and the user's operation position is determined by detecting the change in the capacitance of the capacitive screen. Specifically, when the user touches any position of any capacitive screen, the capacitance of the contact will change , so that the oscillator frequency changes, and the touch position can be determined by measuring the frequency change of the oscillator. [0004] However, the accuracy of determining the user's operation position by detecting the change mode of the capacitance of the capacitive screen is low, and the capacitance of the capacitive screen...
