Hereinafter, a television having a remote control display function on a screen of the present invention will be described in detail with reference to the accompanying drawings.

The present invention performs the same function in place of the mobile remote control, and there is no risk of loss or damage, especially by displaying on the screen of a television. FIG. 2 is a partial block circuit diagram of a television having a remote control display function on a screen of the present invention. In comparison with FIG. 1, the microcomputer 18 receives an electrical signal generated from the touch screen 15a and the touch screen 15a. It can be seen that the remote control input unit 21 is provided with a modulated signal that can be recognized.

In the present invention, the remote control display unit 23 of the same type as the remote control is displayed on the touch screen 15a. The remote controller 23 may input the corresponding data to the OSD generator (not shown), output the call signal, or use liquid crystal display means. That is, it is not normally displayed on the touch screen 15a, but when the viewer presses a specific position, it is displayed on the touch screen 15a so that the viewer can be configured to perform a specific function required by the viewer.

3 is a front view of a television with the remote control display unit 23 displayed on the touch screen 15a. As shown in the figure, the remote control display unit 23 is displayed on the screen by pressing the upper right corner of the screen. Since the remote controller display unit 23 has the same key sequence as the conventional remote controller, the viewer can easily use a specific function key.

The signal generated by pressing the touch screen 15a is input to the remote controller input unit 21. The remote controller input unit 21 outputs a signal to perform a specific function according to the input signal, that is, to perform the same function as the function performed by pressing the conventional remote controller 20. That is, the signals output from the remote controller 20 and the remote controller display unit 23 become the same signal.

The operating state of the television having the remote control display function on the screen of the present invention having the above configuration will be described using the flowchart of FIG.

When the viewer wants to operate the television in a state where the remote control is lost or not currently found, the viewer presses a specific position where the remote control key of the touch screen 15a is set. Due to the pressing pressure, the touch screen 15a displays a remote controller display unit 23 having the same shape as the remote controller as shown in FIG. 3.

The viewer inputs a command by pressing a specific function key in the same manner as the conventional remote controller 20 while the remote controller display unit 23 is displayed. The electrical signal generated by pressing the touch screen 15a is input to the remote controller input unit 21.

The remote controller input unit 21 outputs a signal corresponding thereto based on the input signal. The signal is modulated into a signal input from the microcomputer 18 and input to the microcomputer 18. The microcomputer 18 performs a pre-programmed function based on the input signal. When the execution of the command is completed, the microcomputer 18 maintains the standby state.

This standby state is maintained for a predetermined time, for example, after 10 seconds have elapsed, the remote controller graphic (ICON) showing the remote control display unit 23 on the screen by returning the output state of the remote control display unit 23 displayed on the touch screen 15a. Remove it. Therefore, the viewer can watch television normally after performing a specific function.

The output time of the remote control display section 23 can be arbitrarily set, preferably 5 to 10 seconds for viewing of television.

As described above, according to the present invention, there is an advantage of controlling the television without purchasing a new remote controller even when the remote controller is lost by forming a remote controller input unit on the screen of the television to perform the function of the remote controller.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such variations or modifications will belong to the appended claims. .
