The relays 120 are respectively provided at both ends behind the display part of the above-mentioned mobile communication terminal. At the same time, it is assumed that the electrical conductor 130 moves under the display portion constituted by the guide rail 100 , and is isolated from or combined with the first relay 110 and the second relay 120 . The installation positions or numbers of any specified electrical conductors and relays in the embodiments of the present invention may vary according to specific mobile communication terminals. For reference, Fig. 1a is the first direction of 0 degree rotation; Fig. 1b is the second direction of 90 degree rotation; Fig. 1c is the third direction of 270 degree rotation.

As shown in Figure 1a, when the electrical conductor 130 of the direction detection part is isolated from the first relay 110 and the second relay 120, a certain voltage will be output from the first relay 110 and the second relay 120, so that the direction detection part A 1st direction detection signal will be generated. When the electric conductor 130 of the direction detection part is isolated from the above-mentioned first relay 110 and the second relay 120, the input voltage part (Vin) of the above-mentioned first relay 110 and the second relay 120 constituted as shown in FIG. In the state of receiving any voltage, at the same time, the transistor is in the off state and receives the voltage of +V in the output voltage part (Vout) to output a certain voltage value.

In addition, as shown in FIG. 1b, when the electrical conductor 130 of the direction detection part is combined with the first relay 110, the first relay 110 will not output a voltage value, so the direction detection part will generate a second direction detection signal. When the electric conductor 130 of the above-mentioned direction detection part is combined with the first relay 110, the input voltage part (Vin) of the above-mentioned first relay 110 constituted as shown in FIG.

Referring to FIG. 3 above, during the process of displaying image data on the display unit of the mobile communication terminal, the control unit judges whether a direction detection signal is output from the direction detection unit. When a direction detection signal is output from the direction detection unit, the control unit will detect the above situation in step 301, and read the direction detection signal output from the direction detection unit.

At this time, if the first relay 110 does not output any voltage value, the above-mentioned direction detection part will detect the above situation in step 302 and generate a second direction signal. Direction detection signal. As described above, when the second direction detection signal is generated, it can be determined that the mobile communication terminal is rotated by 90 degrees from the normal direction. In this case, the screen displayed on the display unit of the mobile communication terminal is also in a state rotated by 90 degrees from the normal direction. Therefore, if the user wants to view the screen in the forward direction, the screen displayed above needs to be rotated 90 degrees to the positive direction side.

In Step 303, the control unit rotates the image data displayed on the display unit by 90 degrees to the positive side, and in Step 306, the control unit controls the display unit to display the image data rotated by 90 degrees. In the above step 303, in order to rotate the above image data by 90 degrees to the positive direction side, the above control part will transmit the image data displayed on the resistor (resistor) of the above display part driver (driver), and to make the above image The start position information of the data rotated by 90 degrees. The above-mentioned FIG. 4b illustrates the start position information (B) of the above-mentioned image data output for rotating the above-mentioned image data by 90 degrees.

In addition, if the above-mentioned second relay 120 does not output any voltage value, the above-mentioned direction detection part will detect the above-mentioned situation in step 304 and generate a third direction signal, and at the same time, the above-mentioned control part reads the third direction signal from the above-mentioned direction detection part. heartbeat. As described above, when the third direction detection signal is generated, it can be determined that the mobile communication terminal has rotated 270 degrees from the forward direction. In this case, the screen displayed on the display unit of the mobile communication terminal is also in a state of being rotated 270 degrees from the normal direction. Therefore, if the user wants to observe the screen in the forward direction, the screen displayed above needs to be rotated 270 degrees to the positive direction side.

In Step 305, the control unit rotates the image data displayed on the display unit by 270 degrees in the forward direction, and in Step 306, the control unit controls the display unit to display the image data rotated by 270 degrees. In the above step 305, in order to rotate the above image data by 270 degrees to the positive direction side, the above control part will transmit the image data displayed on the resistor (resistor) of the above display part driver (driver), and to make the above image Data rotation 270 degrees output start position information. The above-mentioned FIG. 4c illustrates the start position information (C) of the above-mentioned image data outputted by rotating the above-mentioned image data by 270 degrees.

Finally, as shown in Figure 4a, when the output of the first relay 110 and the second relay 120 has a certain voltage value, the above-mentioned direction detection part will detect the above-mentioned situation in the above-mentioned step 302 and step 304 and generate the first direction heartbeat. At the same time, the control unit reads the first direction detection signal from the direction detection unit. As mentioned above, when the first direction detection signal is generated, it can be judged that the mobile communication terminal is in the forward direction, so it is only necessary to keep the displayed screen in the forward direction as well. For this reason, the control unit controls the display unit in step 306 so that the display unit displays the screen in the forward direction. In order to maintain the state of the above-mentioned image data in the positive direction, the above-mentioned control part will transmit the image data displayed on the resistor (resistor) of the above-mentioned display part driver (driver), and the start position information output for rotating the above-mentioned image data by 270 degrees . The above-mentioned FIG. 4a illustrates the start position information (A) of the above-mentioned image data for outputting the above-mentioned image data in the forward direction.
