Abstract

PURPOSE: A device for displaying a screen of a portable terminal is provided to sense a direction to which a portable terminal is located, to rotate displayed data according to the sensed direction so as to be located at a forwarding direction, and to display the rotated data, so that a user can always see a forward-directional screen regardless of the portable terminal location. CONSTITUTION: If the second hall sensor(222) senses the first magnet(201) and the third hall sensor(223) senses the second magnet(202), a direction sensor generates the first direction sensing signal. If the second hall sensor(222) senses the first magnet(201), the second direction sensing signal is generated while the fourth direction sensing signal is generated when the first hall sensor(221) senses the first magnet(201). While a folder is shut, the first hall sensor(221) senses the first magnet(201), and the fourth hall sensor(224) senses the second magnet(202). If the first hall sensor(221) and the fourth hall sensor(224) do not sense the first and second magnets(201,202) since the folder is open, the third direction sensing signal is generated. If any direction sensing signal is not outputted from any of the hall sensors(221-224), the third direction sensing signal is generated.

The direction detecting unit 170 detects the direction of the position where the portable terminal is placed and outputs a direction detecting signal to the control unit 110. That is, the direction detecting unit 170 detects the direction according to the position where the portable terminal is placed, and outputs the direction detecting signal to the control unit 110. The direction detecting unit 170 may be implemented in various forms.

3A to 3E are diagrams illustrating the operation of the direction detecting unit 170 according to the first embodiment of the present invention. In the first embodiment of the present invention, four direction sensors are provided in the housing of the main body of the portable terminal and two fixed magnets are mounted in the folder housing of the portable terminal, whereby the display unit 160 of the portable terminal is placed from the sensors. Suppose you detect a open position. In the first embodiment of the present invention, it is assumed that the direction sensors are Hall sensors. The mounting positions or numbers of the sensors and magnets arbitrarily determined in the first embodiment of the present invention may vary depending on the portable terminal used.

Referring to FIG. 3, the direction detecting unit 170 generates a direction detection signal by detecting at least one magnet 201,202 fixed to a folder of the portable terminal and a magnet housing 201,202 mounted on a body housing of the portable terminal. It consists of at least one Hall sensor 221-224. However, the magnets need not be limited to those mounted in the folder of the portable terminal, but may be mounted in the body housing. In addition, the sensors are not limited to those mounted in the main body housing of the portable terminal, and may be mounted in folders. For reference, FIG. 3B means a third direction rotated 180 degrees, FIG. 3C means a fourth direction rotated 270 degrees, FIG. 3D means a second direction rotated 90 degrees, and FIG. 3E is 0 degrees. This will be referred to as the first direction of the direction.

As shown in FIG. 3E, when the second hall sensor 222 senses the first magnet 201 and the third hall sensor 223 detects the second magnet 202, the direction detecting unit 170 generates the first direction detecting signal. In addition, as shown in FIG. 3D, when the second hall sensor 222 detects the first magnet 201, a second direction detection signal is generated. As shown in FIG. 3C, when the first hall sensor 221 senses the first magnet 201, the fourth direction detection signal is generated. Generate. In addition, as shown in FIG. 3A, when the folder of the portable terminal is closed, the first hall sensor 221 senses the first magnet 201, and at the same time, the fourth hall sensor 224 detects the second magnet 202. At this time, if the folder of the portable terminal is opened and the first hall sensor 221 and the fourth hall sensor 224 do not detect the first magnet 201 and the second magnet 202, the third direction detection signal is generated. Alternatively, if the direction detection signal is not output from any hall sensors, the direction detection unit 170 generates a third direction detection signal.

Referring to FIGS. 2 and 3, the operation of the portable terminal having the configuration as shown in FIG. 1 will be described. When the folder housing is spaced apart from the main housing, the controller 110 controls the display unit 160 to perform a display mode. Herein, the display mode includes both a communication mode and a mode for displaying an image signal photographed by the camera 140.

When the display mode is performed, the first hall sensor 221 to the fourth hall sensor 224 of the direction detecting unit 170 sense the magnets 201 and 202 fixed to the portable terminal according to the direction in which the portable terminal is located. The controller 110 reads the output of the direction detecting unit 170 to determine the position where the portable terminal is placed. At this time, when the outputs of the second hall sensor 222 and the third hall sensor 223 are simultaneously detected at the output of the direction detecting unit 170, the position of the current portable terminal is determined as the normal position. In addition, when the output of the second hall sensor 222 is detected, the position of the current portable terminal is determined to be rotated by 90 degrees. When the output of the first hall sensor 201 is detected, the position of the current portable terminal is rotated to 270 degrees. To judge. In addition, if the output signal is not detected from any hall sensors 201-204, the current position of the portable terminal is determined to be rotated 180 degrees. Then, the controller 110 controls the direction of the screen displayed on the display unit 160 according to the output of the direction detection unit 170. Procedures for controlling the display direction of the display unit 160 are the same as those in FIGS. 6 and 7.

6 is a diagram illustrating a procedure for displaying a screen in a portable terminal according to an embodiment of the present invention. Referring to FIG. 6, a method for displaying a screen in the portable terminal including the direction detecting unit 170 as shown in FIG. 3 is as follows.

Referring to FIG. 6, the controller 110 determines whether the current mode is the display mode in step 511. Herein, the display mode refers to a state in which the screen is displayed on the display unit 160 by separating the main body housing and the folder housing. In this case, an initial screen may be displayed on the first display area 161, a date and time may be displayed on the second display area, and a reception sensitivity and a remaining battery capacity may be displayed on the third display area. In the camera mode, the camera image captured by the camera unit 140 may be processed by the image processor 150 to be displayed on the first display area of the display unit 160. In the data communication mode, all of the first to third screen display areas 161 to 163 are used to display text information in the case of text communication, and the first screen display area as described above in the case of video mail communication. The video signal received at 161 is displayed. The first screen display area 161 is an area for displaying a QCIF size as described above.

When the automatic display change mode is set in the display mode as described above, the controller 110 detects this in step 513. Here, the automatic display change mode refers to a mode for automatically controlling the direction of the screen displayed on the display unit 160 according to the direction detection signal of the direction detecting unit 170. Therefore, when the automatic display change mode is not set, the controller 110 displays the screen in a fixed direction (first direction; 0 degrees) regardless of the output of the direction detecting unit 170.

However, when the automatic display change mode is set, the controller 110 determines whether the direction detection signal is output from the direction detection unit 170. When the direction detecting signal is output from the direction detecting unit 170, the control unit 110 detects this in step 514, and in step 515 reads the direction detecting signal output from the direction detecting unit 170.

At this time, if the second hall sensor 222 detects the first magnet 201 and at the same time the third hall sensor 223 detects the second magnet 202, the direction detecting unit 170 generates a first direction detection signal in step 514, the control unit 110 In step 515, the first direction detection signal is read. When the first direction detection signal is generated as described above, since the portable terminal is located in the forward direction, the displayed screen may be maintained in the forward direction. Accordingly, the control unit 110 detects this in step 517 and controls the display unit 160 to display the screen in the forward direction in step 529. 3E illustrates a state where the portable terminal is located in the forward direction.

However, when the first hall sensor 221 detects the second magnet 201, the direction detecting unit 170 generates a second direction detecting signal in step 514, and the control unit 110 reads the second direction detecting signal in step 515. . When the second direction detection signal is generated as described above, it means that the portable terminal is rotated 90 degrees in the forward direction. In this case, the screen displayed on the display unit 160 is also rotated 90 degrees in the forward direction. Therefore, in order to allow the user to see the screen in the forward direction, the screen being displayed must be rotated 90 degrees toward the forward side. Therefore, the control unit 110 detects this in step 519 and rotates the display data applied to the display unit 160 by 90 degrees in step 521, and displays the display data rotated by 90 degrees by controlling the display unit 160 in step 529. . Therefore, the user of the portable terminal can see the screen in the forward direction displayed on the display unit 160 even when the portable terminal is rotated 90 degrees. 3d illustrates that the portable terminal is rotated 90 degrees in the forward direction.

In addition, if no signal is output from the hall sensors 221-224, the direction detecting unit 170 detects it in step 514 and generates a third direction detecting signal. Alternatively, as shown in FIG. 3A, when the folder of the portable terminal is closed, the first hall sensor 221 senses the first magnet 201, and at the same time, the fourth hall sensor 224 detects the second magnet 202. In this case, when the folder of the portable terminal is opened and the first hall sensor 221 and the fourth hall sensor 224 do not detect the first magnet 201 and the second magnet 202, the direction detecting unit 170 generates a third direction detecting signal. The controller 110 reads the third direction detection signal in step 515. When the third direction detection signal is generated as described above, it means that the portable terminal is rotated 180 degrees in the forward direction. In this case, the screen displayed on the display unit 160 is also rotated 180 degrees in the forward direction and displayed in reverse. Therefore, in order to allow the user to see the screen in the forward direction, the displayed screen should be rotated 180 degrees toward the forward side. Therefore, the controller 110 rotates the display data applied to the display unit 160 by 180 degrees in the forward direction in step 525, and displays the display data rotated by 180 degrees by controlling the display unit 160 in step 529. Accordingly, the user of the portable terminal can see the screen in the forward direction displayed on the display unit 160 even when the portable terminal is rotated 180 degrees. 3b shows that the portable terminal is rotated 180 degrees in the forward direction.

Finally, when the first hall sensor 221 detects the first magnet 201, the direction detecting unit 170 generates a fourth direction detecting signal in step 514, and the control unit 110 reads the fourth direction detecting signal in step 515. . When the fourth direction detection signal is generated as described above, it means that the portable terminal is rotated 270 degrees in the forward direction. In this case, the screen displayed on the display unit 160 is also displayed to be rotated 270 degrees in the forward direction. Therefore, in order to allow the user to see the screen in the forward direction, the display screen should be rotated 270 degrees toward the forward direction. Accordingly, the control unit 110 detects this in step 519 and rotates the display data applied to the display unit 160 in the forward direction in step 527, and controls the display unit 160 in step 529 to display the display data rotated by 270 degrees. . Therefore, the user of the portable terminal can see the forward screen displayed on the display unit 160 even when the portable terminal is rotated 270 degrees. 3c shows that the portable terminal is rotated 270 degrees in the forward direction.

As described above, by detecting the direction in which the portable terminal is located through the direction detecting unit 170, and by rotating the data displayed on the display unit 160 to the forward direction by the rotated direction of the portable terminal, the user is located at the position of the portable terminal You can always see the display in the forward direction. In this case, when the screen of the display unit 160 is rotated and displayed, a problem may occur when displaying the second and fourth directions when the displayed screen has a predetermined size. That is, when the image signal photographed by the camera is displayed in the QCIF size, the display in the first direction and the third direction may be normally performed, but it is difficult to display the QCIF size in the second and fourth directions. Therefore, in the above case, it is preferable to display in full size.

As described above, when processing display data fixed to a screen having a predetermined size, such as a QCIF screen, only the display data is controlled in the first and third directions, and the size of the display data is displayed in the second and fourth directions. It is preferable to control the direction of the regenerated display data in the corresponding direction while generating the readjusted data.

FIG. 7 illustrates another method of controlling a display operation in a mobile terminal according to an embodiment of the present invention. In the first and third directions, the display data is controlled by QCIF size, and the second and fourth directions are controlled. In the description, it is assumed that the display data is controlled to the full screen size. Referring to FIG. 7, a method for displaying a screen in the portable terminal configured as the direction detecting unit 170 as shown in FIG. 3 is as follows.

Referring to FIG. 7, the controller 110 checks whether the current mode is the display mode in step 611. Here, the display mode is a state in which the screen is displayed on the display unit 160 by separating the main body housing and the folder housing, which is the same as the display mode of FIG. 6. In this case, the controller 110 detects this in the display mode state. When the automatic display change mode is set in the display mode as described above, the control unit 110 detects this in step 612, where the automatic display change mode is the same as the automatic display change mode of FIG. 6.

When the automatic display change mode is set as described above, the controller 110 determines whether the direction detection signal is output from the direction detection unit 170. When the direction detection signal is output from the direction detection unit 170, the control unit 110 detects it in step 613, and in step 614, the direction detection signal output from the direction detection unit 170 is read.

At this time, if the second hall sensor 222 detects the first magnet 201 and at the same time the third hall sensor 223 detects the second magnet 202, the direction detecting unit 170 generates a first direction detecting signal in step 613, the control unit 110 In step 614, the first direction detection signal is read. When the first direction detection signal is generated as described above, since the portable terminal is located in the forward direction, the displayed screen may be maintained in the forward direction. Accordingly, the control unit 110 detects this in step 615, generates data of QCIF size as the first display data in step 617, and controls the display unit 160 to display the QCIF screen in the forward direction in step 635.

However, when the first hall sensor 221 detects the second magnet 201, the direction detecting unit 170 generates a second direction detecting signal in step 613, and the control unit 110 reads the second direction detecting signal in step 614. . When the second direction detection signal is generated as described above, it means that the portable terminal is rotated 90 degrees in the forward direction. In this case, the screen displayed on the display unit 160 is also rotated 90 degrees in the forward direction. Therefore, in order to allow the user to see the screen in the forward direction, the screen being displayed must be rotated 90 degrees toward the forward side. In addition, in the second direction, the display unit 160 should generate the second display data to display the full size screen without displaying the QCIF size screen. Therefore, the control unit 110 detects this in step 619, and generates second display data, which is display data having the full screen size, from the display data of the QCIF size in step 621, and forwards the generated second display data to the forward side in step 623. Rotate 90 degrees The controller 110 controls the display unit 160 to display the second display data rotated 90 degrees toward the forward side in step 635. Therefore, the user of the portable terminal can see the forward screen displayed on the display unit 160 even when the portable terminal is rotated 90 degrees.

In addition, if no signal is output from the hall sensors 221-224, the direction detecting unit 170 detects it in step 613 and generates a third direction detecting signal. Alternatively, as shown in FIG. 3A, when the folder of the portable terminal is closed, the first hall sensor 221 senses the first magnet 201, and at the same time, the fourth hall sensor 224 detects the second magnet 202. In this case, when the folder of the portable terminal is opened and the first hall sensor 221 and the fourth hall sensor 224 do not detect the first magnet 201 and the second magnet 202, the direction detecting unit 170 generates a third direction detecting signal. When the third direction detection signal is generated as described above, it means that the portable terminal is rotated 180 degrees in the forward direction. In this case, the screen displayed on the display unit 160 is also rotated 180 degrees in the forward direction and is displayed in reverse. Therefore, in order to allow the user to see the screen in the forward direction, the displayed screen should be rotated 180 degrees toward the forward side. Accordingly, the control unit 110 detects this in step 613 and generates first display data having a QCIF size in step 627. In step 629, the control unit 110 rotates the first display data applied to the display unit 160 by 180 degrees in the forward direction. The display unit 160 controls the display unit 160 to display the first display data rotated 180 degrees. Accordingly, the user of the portable terminal can see the screen in the forward direction displayed on the display unit 160 even when the portable terminal is rotated 180 degrees.

Finally, when the first hall sensor 221 senses the first magnet 201, the direction detecting unit 170 generates a fourth direction detecting signal in step 613, and the control unit 110 reads the fourth direction detecting signal in step 614. . When the fourth direction detection signal is generated as described above, it means that the portable terminal is rotated 270 degrees in the forward direction. In this case, the screen displayed on the display unit 160 is also displayed to be rotated 270 degrees in the forward direction. Therefore, in order to allow the user to see the screen in the forward direction, the display screen should be rotated 270 degrees toward the forward direction. In addition, in the fourth direction, the display unit 160 should generate the second display data to display the full size screen without displaying the QCIF size screen. Therefore, the control unit 110 detects this in step 619, and generates second display data, which is display data having the full screen size, from the display data of the QCIF size in step 631, and the second display applied to the display unit 160 in step 633. The data is rotated 270 degrees in the forward direction, and the display unit 160 is controlled in step 635 to display the second display data rotated by 270 degrees. Therefore, the user of the portable terminal can see the screen in the forward direction displayed on the display unit 160 even when the portable terminal is rotated 270 degrees.

The portable terminal for controlling the display data according to the procedure of FIG. 7 may be a portable terminal having the configuration as shown in FIG. 1. That is, in the case of a portable terminal which performs only general communication procedures such as text communication, the direction of the display data may be controlled according to the position where the portable terminal is placed while the size of the display data is not controlled while performing the procedure of FIG. 6. . However, in the case of a portable terminal having the camera, the display data photographed by the camera unit 40 is displayed at a constant size. In this case, since the display data has a size set to be displayed in the first direction, it is preferable to also adjust the size of the displayed data when displaying in the second and fourth directions.

At this time, if the folder of the portable terminal is opened and the first and third hall sensors 321 and 323 do not detect the third protrusion 303 and the fourth protrusion 304, a third direction detection signal is generated. Alternatively, if no direction detection signal is output from the hall sensors 321 to 323, the direction detection unit 170 generates the third direction detection signal.

The controller 110 reads the output of the direction detecting unit 170 to determine the position where the portable terminal is placed. At this time, if the outputs of the second hall sensor 322 and the third hall sensor 323 are simultaneously detected at the output of the direction detecting unit 170, the position of the current portable terminal is determined as the normal position. In addition, when the output of the second Hall sensor 322 is detected, the position of the current portable terminal is determined to be rotated by 90 degrees.
