Embodiment
Direction recognition device and control method thereof to image display of the present invention is elaborated below with reference to accompanying drawings.
With reference to Fig. 1 as can be known, the computer system according to example of the present invention is made of image display 100, PC main frame 104 and input equipment 106.
Above-mentioned image display 100 can rotate 0 °, 90 °, 180 ° and 270 ° respectively according to user's hobby.
In this case, direction can or counterclockwise be rotated according to clockwise direction.Above-mentioned Fig. 1 has demonstrated image display 100 under the normal state and image display under the normal state 100 and has been rotated image display 102 under 90 ° of states according to clockwise direction.
The outboard profile of above-mentioned image display 100,102 has been installed the sensor 406 that can discern the anglec of rotation as shown in Figure 4.
Fig. 2 is the pie graph that shows the image display with direction recognition function that is applicable to aforementioned calculation machine system.With reference to Fig. 2 as can be known, the sensor 202 that has in the image display 200 can recognize the rotation status of image display 200, and provides and the corresponding output signal of image display rotation status.
The output signal that the sensor 202 is provided is transferred to the control device 204 of image display 200,204 pairs of above-mentioned output signals of above-mentioned control device are carried out the A/D conversion, and from signal, detect present rotation status, generation can demonstrate the detection information of detected rotation status, offers PC main frame 300 by interface arrangement 206.
The control device 304 of above-mentioned PC main frame 300 receives rotation status by interface arrangement 302 from image display 200 and detects information, and whether decision moves picture format converse routine 306.300 employed interfaces of above-mentioned image display 200 and PC main frame are USB interface or DDC communication interface.
Can the formation of the sensor be elaborated with reference to Fig. 3 and Fig. 4.
Fig. 3 is the rear view according to image display of the present invention.Fig. 4 is the lateral plan according to image display of the present invention.
Connect the strong point structure that the bracing frame 402 of above-mentioned image display 404 and bottom base 400 can make image display 404 rotate freely.
Simultaneously, the sensor 406 that can recognize 404 rotations of above-mentioned image display and coupled each switch SW 1, SW2, SW3, SW4 are installed on the bracing frame at image display 404 back sides.
Above-mentioned each switch is installing one respectively up and down, and along with the rotation of image display 404, particular switch just is connected with sensor 406, thereby just can recognize the sense of rotation of image display 404.
With reference to Fig. 5 the ruuning situation of the sensor is elaborated.
The 1st switch SW 1 one end ground connection, the other end is connected with the 1st resistance R 1; The 2nd switch SW 2 one end ground connection, the other end is connected with the other end of the 1st resistance R 1 and an end of the 2nd resistance R 2; The 3rd switch SW 3 one end ground connection, the other end is connected with the other end of the 2nd resistance R 2 and the end of R3; The 4th switch SW 4 one ends are connected other end ground connection with the other end of above-mentioned the 3rd resistance R 3 and an end of the 4th resistance R 4; The other end of above-mentioned the 4th resistance R 4 is connected with power Vcc.
Above-mentioned the 1st to the 4th switch SW 1 to SW4 can be come the change-over switch state according to the rotation of image display 404.
For example,, then only connect the 1st switch SW 1, be connected with the 1st, 2 between power supply and the ground if image display 404 is in normal state, 3,4 resistance R 1, R2, R3, R4, according to the 1st, 2,3 resistance R 1, R2, the voltage that the combined resistance of R3 and the 4th resistance R 4 are distributed comes transmission output signal.
By this process, sensor 406 can will be transferred to microcomputer 500 with the corresponding output signal of the rotation status of image display 404.
With reference to Fig. 6 foundation image display direction is illustrated picture signal output format transfer process below.
The sensor 406 detected output signals are provided for microcomputer 500,500 pairs of above-mentioned output signals of above-mentioned microcomputer are carried out the A/D conversion, and detect present sense of rotation, generation can show the direction display message of detected sense of rotation state, offers the PC main frame by interface arrangement.
The control device 304 of above-mentioned PC main frame receives the direction display message of coming from sensor transmissions by interface arrangement 302, and operation and picture set relevant picture format converse routine 306, is converted to the output format of picture signal corresponding with the sense of rotation of image display.
