The disclosure of this paper is incorporated herein by reference. 6 201248607 According to the =====, the processing unit 120 depends on the image direction of the image (step 330). = Step measurement. For example, as shown in Figure i, in the user's voice, 曰: 4, the display device 100 will automatically change/rotate the image correspondingly. The user who makes the voice can conveniently view the display module u〇. Therefore, a plurality of users can view the image displayed by the display device 100 in different directions more conveniently and friendlyly without manually rotating the horizontal angle of the entire display device 100. FIG. 4 is in accordance with FIG. Another embodiment of the present invention is a schematic flow chart of the operation method of the display device 100 shown in Figure 2. The embodiment shown in Figure 4 can refer to the related description of Figure 3. The step 33 of Figure 4 includes sub-steps. S332 and S334. Referring to FIG. 2 and FIG. 4, after the processing unit 12 obtains the sound source direction in step S32, the processing unit 120 then determines whether the sound emitted by the sound source (user) is a voice command' and the voice command. Whether it is a "steering command". If the voice command issued by the sound source is not the preset "steering command", the display device 100 returns to step S310 without changing the image direction. Otherwise, if the voice command issued by the sound source is "steering command" The processing unit 120 controls the display module 110 according to the direction of the sound source to cause the display module 110 to change the image direction (step 334). After completing step 334, the display device 100 returns to step S310. The "steering command" is It is set according to the product design requirements and/or the application requirements of the user. For example, in this embodiment, the steering command is set to "please turn" or "turnpleasej. For example, as shown in FIG. 1 in multiple user phases 201248607 mutual The noisy %<in the environment' display device will determine whether the user's voice is a #direction command to avoid the display device (10). However, the direction of the image is changed/rotated. During the discussion of these users, if there is, the user of the middle position wants to view the display device. The displayed image, the user can view the display device. 〇 Speaking "Please turn" or "turn please" (ie, after turning to the command display device 1 to determine that the user's voice is a "steering command", the processing unit 12 will proceed to step 334 ' to issue " The sound source direction control display module 110' of the steering command "automatically changes/rotates the image direction" correspondingly to the display module 11's to facilitate the user who has issued the "steering command" to conveniently view the image displayed by the display module u. 5A and 5B are schematic diagrams showing an application scenario of a display device 1A according to an embodiment of the invention. This example will assume that the display device 1 is configured with two sound sensors 130-1 and 130-2 (i.e., n = 2). The sound sensors 130-1 and 130-2 are respectively disposed on the opposite sides of the display device 1A. Referring to FIG. 5A', when the user U1 (sound source) emits a sound to the display device 1, the sound sensors 130-1 and 130-2 can detect the sound of the user ui. Since the sound sensor 130-1 is closer to the user U1' than the sound sensor 130-2, the volume detected by the sound sensor 130-1 is greater than the volume detected by the sound sensor 130-2. Therefore, the processing unit 120 can determine the direction of the sound source by comparing the volume measured by the sound sensors 13〇-1 and 130-2 in step S320.
