REMOTE CONTROL DEVICE FOR DISPLAY SCREEN AND METHOD FOR REMOTELY CONTROLLING DISPLAY SCREEN
First Claim
1. A remote control device for a display screen, comprising at least three distance sensor receivers that are fixed with respect to the display screen and arranged at different positions, a control pen and a control point recognition unit, wherein the control pen is provided with at least two distance sensor transmitters at positions in different distances to a pen tip;
- the at least three distance sensor receivers are configured to receive ranging signals from the at least two distance sensor transmitters, respectively;
the control point recognition unit is configured to determine a control point of the control pen on the display screen based on the ranging signals received by the at least three distance sensor receivers.

Abstract
The example embodiments of the present disclosure relate to a remote control device for a display screen and a method for remotely controlling a display screen. The remote control device comprises at least three distance sensor receivers that are fixed with respect to the display screen and arranged at different positions, a control pen and a control point recognition unit, wherein the control pen is provided with at least two distance sensor transmitters at positions in different distances to a pen tip; the at least three distance sensor receivers are configured to receive ranging signals from the at least two distance sensor transmitters, respectively; the control point recognition unit is configured to determine a control point of the control pen on the display screen based on the ranging signals received by the at least three distance sensor receivers. According to the example embodiments of the present disclosure, a control of the display screen is no longer limited by the distance, while the control pen is not contacted with the display screen directly to avoid the display screen from being scraped.
