Title: DISPLAY SCREEN, STYLUS AND DISPLAY MODULE
Abstract:
A display screen, a stylus and a display module. The display screen comprises a frame (7), a touch control display panel (1), a controller and a plurality of acoustic wave collectors (2), wherein the plurality of acoustic wave collectors (2) are arranged at different positions on the frame (7) and on the same side with a working surface of the touch control display panel (1). The acoustic wave collectors (2) collect an acoustic wave signal (6) emitted by an acoustic wave emission source (5), and input the collected acoustic wave signal (6) into the controller; the touch control display panel (1) collects an electromagnetic signal emitted by an electromagnetic generation apparatus and inputs the collected electromagnetic signal into the controller; the controller determines, according to the electromagnetic signal and the acoustic wave signal (6) emitted by the acoustic wave emission source (5) in various styluses, the actual touch control positions of various styluses on the touch control panel (1), thereby achieving the purpose of accurate positioning, and at the same time recognizing and accurately positioning different active styluses according to different frequency bands of the acoustic wave signals (6) corresponding to various styluses.
