Control method of plasma TV, a bluetooth touch control pen and a plasma TV

摘要

Disclosed are a control method of plasma TV, a Bluetooth touch control pen and a plasma TV, the method comprising: configuring all or part of the pixel points of a plasma TV screen to transmit a light signal carrying pixel position information; a touch control pen receiving the light signal by contacting the screen, calculating the pixel coordinate values of the position of a contact point on the screen according to the pixel position information in the light signal, and transmitting the calculated pixel coordinate values to the plasma TV via Bluetooth transmission; the plasma TV conducting a corresponding operation according to the received pixel coordinate values. The present invention realizes a novel touch control solution for large screen plasma TVs, and the solution has good user experience and low cost.

1. A control method of plasma TV, the method comprising the steps of:
configuring all or part of the pixel points of a plasma TV screen to transmit a light signal carrying pixel position information, the pixel position information including a time point of screen-updating synchronizing signal, a time point of updating a pixel residing line and a time point of updating a pixel residing column; contacting the screen with a touch control pen to receive the light signal, the touch control pen contacting the screen at a contact point; calculating pixel coordinate values of the contact point on the screen according to the pixel position information in the light signal; and transmitting the calculated pixel coordinate values to the plasma TV via a short-range wireless transmission; conducting a predetermined operation or displaying a drawing in the corresponding pixel position with the plasma TV according to the pixel coordinate values received by the plasma TV:wherein:
the pixel coordinate values of the contact point on the screen are calculated according to the steps of:
obtaining an ordinate value of a pixel according to the time difference between the time point of updating the pixel residing line and the time point of screen-updating synchronizing signal; andobtaining an abscissa value of the pixel according to the time difference between the time point of updating the pixel residing column and the time point of screen-updating synchronizing signal.
