In addition, the same or similar reference numbers refer to the same or similar components, and are not repeated in the following paragraphs.
Fig. 1 is a schematic diagram of a display device according to an embodiment of the present invention. Referring to fig. 1, the display device 100 includes a display panel 110, a sound generating module SM, an image analyzing circuit 120, a sound driving circuit 130, a timing controller 140, a source driver 150, and a gate driver 160. In the present embodiment, the display panel 110 has a plurality of display units DA11 to DANM therein, wherein the display units DA11 to DANM are arranged in a matrix manner, and N, M is a positive integer. The sound generation module SM has a plurality of sound generation elements SC11 to SCNM, wherein the sound generation elements SC11 to SCNM are arranged in a matrix, and the sound generation elements SC11 to SCNM are arranged in at least one-to-one correspondence with the display units DA11 to DANM, respectively. For example, the sound generating element SC11 may be disposed to overlap the display unit DA11, the sound generating element SC21 may be disposed to overlap the display unit DA21, and the like, but the invention is not limited thereto.
Next, in the present embodiment, the image analysis circuit 120 may receive the image signal IM, and the image analysis circuit 120 is configured to analyze a position of at least one sound-emitting object in the display screen. Then, the image analysis circuit 120 can correspondingly provide the utterance information VI according to the position of the utterance object. The sound source object may be a sound source object in the display screen (such as a speaker, a mouth, a car, a bursting point, or other suitable source objects, or a combination of the foregoing source objects, but the invention is not limited thereto).
On the other hand, in the present embodiment, the sound driving circuit 130 is coupled between the sound generating module SM and the image analyzing circuit 120 to receive the sound signal VS and the sound generating information VI. The sound driving circuit 130 is configured to determine at least one first display unit of the plurality of display units DA 11-DANM overlapped by the at least one sound object according to the sound information VI. Also, the display device 100 may increase or adjust the sound emission loudness of the sound emission elements SC11 to SCNM corresponding to the first display unit by using the sound driving circuit 130. Wherein, the first display unit is at least one of the display units DA 11-DANM according to the size of the sound-emitting object. Furthermore, in the embodiment of the invention, each of the display units DA 11-DANM respectively corresponds to a plurality of pixels arranged in an array, and the display units DA 11-DANM are not overlapped with each other. The sound-emitting elements SC11 to SCNM corresponding to (or overlapping) the display units DA11 to DANM, respectively, can emit sound in response to the sound-emitting object on the display screen.
In addition, in the embodiment, the timing controller 140 is coupled to the image analysis circuit 120 to receive the image signal IM, and the timing controller 140 can generate the corresponding control signal CS1 and the control signal CS2 according to the image signal IM. The gate driver 160 is coupled between the display panel 110 and the timing controller 140 to receive the control signal CS1, and the gate driver 160 can be controlled by the timing controller 140 to transmit a plurality of gate signals G1 GN to the display panel 110. In addition, the source driver 150 of the present embodiment is coupled between the display panel 110 and the timing controller 140 to receive the control signal CS2, and the source driver 150 can be controlled by the timing controller 140 to transmit the data voltages S1-SN to the display panel 110. In the embodiment of the invention, a person skilled in the art can determine the number of the display units DA 11-DANM and the sounding elements SC 11-SCNM in the display panel 110 according to the design requirement of the display panel 110.
Fig. 2 is a diagram illustrating allocation of voicing loudness of a voicing object on a display unit in accordance with an embodiment of the present invention. Referring to fig. 1 and fig. 2, in fig. 2, squares in the display panel 210 indicate display units DA 11-DANM in the display panel 110, and are arranged in a matrix of 4 × 6 for example, but the embodiment of the invention is not limited thereto. In the present embodiment, when a single sound object SO42 appears in the display screen, since the sound object SO42 only overlaps with the display unit DA42 (corresponding to the first display area), the sound loudness of the whole sound module SM can be concentrated on the sound generating element (e.g., SC42) overlapping with the display unit DA42, that is, the sound generating element (e.g., SC42) overlapping with the display unit DA42 is solely used for generating sound, and the sound generating element (e.g., SC43) overlapping with the other sound generating elements (e.g., the display unit or the table indicated by the right diagonal line in the display panel 210) is not used for generating sound. Viewed from another point, in the present embodiment, the sound emitting loudness of the sound emitting element corresponding to the first display unit (i.e., the display unit DA42) may be substantially equal to the total loudness of the sound emitting module SM.
In another embodiment, the display unit DA42 may serve as a primary sound emission position of the sound emission module SM, and the other display units DA43 may serve as secondary sound emission positions of the sound emission module SM. Viewed from another point, the sound emitting loudness of the sound emitting elements (such as SC42) corresponding to (or overlapping) the display unit DA42 is greater than the sound emitting loudness of the sound emitting elements (such as SC43) corresponding to (or overlapping) the other display units DA 43. That is, the sound emission loudness of the sound emission element in the primary sound emission position (e.g., SC42) may be greater than the sound emission loudness of the sound emission element in the secondary sound emission position (e.g., SC 43).
For example, if the sound emission loudness of the sound emission element (e.g., SC42) overlapping with the display unit DA42 accounts for about 60% of the total loudness of the sound emission module SM, it means that the sound emission loudness of the sound emission element (e.g., SC43) overlapping with the other display units DA43 accounts for about 40% of the total loudness of the sound emission module SM. Moreover, about 40% of the total loudness of the sound generating module SM may be substantially evenly distributed among the sound generating elements (e.g., SC43) overlapped with the other display units DA43, i.e., the loudness of the other sound generating elements (e.g., SC43) overlapped with the other display units DA43 is substantially equal. The sum of the sound emitting loudness of the sound emitting element (for example, SC42) overlapped with the display unit DA42 and the sound emitting loudness of the sound emitting element (for example, SC43) overlapped with the other display unit DA43 is substantially equal to the total loudness of the sound emitting module SM. In addition, the loudness distribution ratios allocated to the display units (e.g., DA11 DANM) may be adjusted according to the display frames of the display panel 210 according to the embodiments of the present invention, but the embodiments of the present invention are not limited to the loudness distribution ratios exemplified above.
Note that, in order to avoid the complexity of the drawing, the display panel 210 in fig. 2 only has two squares indicated by diagonal lines to indicate the corresponding display unit DA43 and sound generating element SC 43. That is, each of the squares in the display panel 210 shown by the diagonal lines on the right may correspond to the display unit DA43 and the sounding element SC43, respectively, but the embodiment of the invention is not limited to the display unit and the sounding element illustrated above.
Fig. 3 is a schematic diagram illustrating allocation of voicing loudness of a voicing object on a display unit in accordance with another embodiment of the present invention. Referring to fig. 1 and fig. 3, the squares in the display panel 310 represent the display units DA 11-DANM in the display panel 110 and are arranged in a matrix of 4 × 6, but the embodiment of the invention is not limited thereto. For example, when a single sound emission object SO42 appears in the display screen, the display unit DA42 may serve as a main sound emission position of the sound emission module SM because the sound emission object SO42 only overlaps with the display unit DA42 (corresponding to the first display area). In addition, other display units DA44 (for example, display units or tables indicated by right-diagonal lines in the display panel 310) and display units DA45 (for example, display units or tables indicated by left-diagonal lines in the display panel 310) may be used as auxiliary sound emission positions of the sound emission module SM.
In the present embodiment, when the display unit DA42 is used as the main sound emission position of the display screen, the sound emission loudness of the sound emission elements (e.g., SC11 to SCNM) of the sound emission module SM may gradually decrease from the main sound emission position toward the auxiliary sound emission position. Viewed from another direction, the sound emission loudness of the sound emission elements (e.g., SC42) corresponding to (or overlapping) the first display unit (e.g., display unit DA42) may be greater than the sum of the sound emission loudness of the sound emission elements (e.g., SC44) corresponding to (or overlapping) the plurality of second display units DA44 adjacent to the first display unit (e.g., display unit DA 42). Moreover, the sum of the sound emitting loudness of the sound emitting elements (such as SC44) corresponding to (or overlapping) the second display unit DA44 may be greater than the sum of the sound emitting loudness of the other sound emitting elements (such as SC45) corresponding to (or overlapping) the other display units DA45 in the sound emitting module SM. The loudness of the sound emitting elements (such as SC44) corresponding to (or overlapping) the second display unit DA44 is substantially equal, and the loudness of the other sound emitting elements (such as SC45) corresponding to (or overlapping) the other display units DA45 is substantially equal. In the present embodiment, the loudness emitted by the sound generating elements (e.g., SC42, SC44 and SC45) corresponding to all the display units (e.g., DA42, DA44 and DA45) in the display panel 310 is substantially equal to the total loudness of the sound generating module SM.
Note that, in order to avoid the complexity of the drawing, the display panel 310 in fig. 3 only shows the corresponding display unit DA44 and the corresponding sound emitting element SC44 as a square represented by a diagonal line. That is, each of the squares indicated by the right-diagonal lines in the display panel 310 can correspond to the display unit DA44 and the sounding element SC44, respectively. Similarly, in the display panel 310, the display unit DA45 and the sound emitting element SC45 corresponding thereto are indicated by only one square indicated by diagonal lines. That is, each of the squares in the display panel 310 represented by the left diagonal lines may correspond to the display unit DA45 and the sounding element SC45, respectively, but the embodiment of the present invention is not limited to the display unit and the sounding element illustrated above.
Fig. 4 is a diagram illustrating allocation of voicing loudness of a voicing object on a display unit in accordance with yet another embodiment of the present invention. Referring to fig. 1 and fig. 4, the squares in the display panel 410 represent the display units DA 11-DANM in the display panel 110 and are arranged in a matrix of 4 × 6, but the embodiment of the invention is not limited thereto. In the present embodiment, when a single sound emission object SO43 appears in the display screen, since the sound emission object SO43 overlaps the display units DA42_1 to DA42_4 (corresponding to the first display area), the sound emission loudness of the entire sound emission module SM can be concentrated on the display units DA42_1 to DA42_4, SO that the sound emission elements (e.g., SC42_1 to SC42_4) corresponding to the display units DA42_1 to DA42_4, respectively, can emit sound at the same time. In the present embodiment, the loudness of the generated sound generated by the sound generating elements (e.g., SC42_ 1-SC 42_4) corresponding to the display units DA42_ 1-DA 42_4 is substantially equal. In this case, no other display unit DA43 (e.g., the display unit or table shown by the diagonal lines in the display panel 410) in the display panel 410 performs the sound emitting operation. Viewed from another direction, in the present embodiment, the total loudness of the sound emitting elements (e.g., SC42_1 to SC42_4) corresponding to the display units DA42_1 to DA42_4 may be substantially equal to the total loudness of the sound emitting module SM. Also, the total loudness of the sound emission module SM may be substantially evenly distributed to each of the sound emission elements (e.g., SC42_1 to SC42_4) corresponding to the display units DA42_1 to DA42_ 4.
In some cases, the display units DA42_1 to DA42_4 of the present embodiment may serve as main sound emission positions of the sound emission module SM. In addition, the sound generating elements (such as SC43) corresponding to (or overlapping) the other display units DA43 can be used as auxiliary sound generating positions of the sound generating module SM. Wherein, the sounding loudness of the sounding elements (such as SC42_ 1-SC 42_4) at the main sounding position can be larger than the sounding loudness of the sounding elements (such as SC43) at the auxiliary sounding position. In this case, the loudness of the sound elements (e.g., SC42_1 to SC42_4) overlapped with the display units DA42_1 to DA42_4 is substantially equal, and the loudness of the sound elements (e.g., SC43) corresponding to the other display units DA43 is substantially equal.
In another embodiment, the sound emitting elements (e.g., SC42_1 to SC42_4) overlapped with the display units DA42_1 to DA42_4 can respectively set the sound emitting loudness according to the area ratio of the display units DA42_1 to DA42_4 where the sound emitting object SO43 is located. For example, the sound emitting element (e.g., SC42_1) overlapped with the display unit DA42_1 sets the sound emitting loudness according to the area ratio of the sound emitting object SO43 in the display unit DA42_ 1; the sound emitting element (for example, SC42_2) overlapping the display unit DA42_2 sets the sound emitting loudness according to the area ratio of the sound emitting object SO43 in the display unit DA42_2, and the rest is similar. For example, when the display unit DA42_2 in which the sound object SO43 is located occupies a larger area ratio than the display unit DA42_1, the sound generating loudness of the sound generating element (e.g., SC42_2) corresponding to the display unit DA42_2 may be greater than the sound generating loudness of the sound generating element (e.g., SC42_1) corresponding to the display unit DA42_ 1. In contrast, when the display unit DA42_4 in which the sound emission object SO43 is located occupies a larger area ratio than the display unit DA42_3, the sound emission loudness of the sound emission element (e.g., SC42_4) corresponding to the display unit DA42_4 may be larger than the sound emission loudness of the sound emission element (e.g., SC42_3) corresponding to the display unit DA42_ 3.
Note that, in order to avoid the complexity of the drawing, in the display panel 410 of fig. 4, the display unit DA43 and the sound emitting element SC43 corresponding thereto are only represented by a square indicated by a diagonal line. That is, each of the squares indicated by the diagonal lines on the display panel 410 may correspond to the display unit DA43 and the sounding element SC43, respectively, but the embodiments of the present invention are not limited to the display unit and the sounding element illustrated above.
Fig. 5 is a diagram illustrating allocation of voicing loudness of a voicing object on a display unit in accordance with a further embodiment of the present invention. Referring to fig. 1 and 5, the squares in the display panel 510 represent the display units DA 11-DANM in the display panel 110 and are arranged in a matrix of 4 × 6, but the embodiment of the invention is not limited thereto. When a single sound emission object SO42 appears in the display screen, the display units DA42_1 to DA42_4 can serve as the main sound emission positions of the sound emission module SM because the sound emission object SO42 overlaps with the display units DA42_1 to DA42_4 (corresponding to the first display area). In addition, other display units DA44 (for example, display units or tables indicated by right-diagonal lines in the display panel 510) and display units DA45 (for example, display units or tables indicated by left-diagonal lines in the display panel 510) may be used as auxiliary sound emission positions of the sound emission module SM.
For example, in the present embodiment, when the display units DA42_1 to DA42_4 are used as the main sound emission positions of the display screen, the sound emission loudness of the sound emission elements (e.g., SC11 to SCNM) of the sound emission module SM may gradually decrease from the main sound emission positions to the auxiliary sound emission positions. Viewed from another aspect, the sound emission loudness of the sound emission elements (e.g., SC42_1 to SC42_4) corresponding to (or overlapping) the first display units (e.g., display units DA42_1 to DA42_4) may be greater than the sum of the sound emission loudness of the sound emission elements (e.g., SC44) corresponding to (or overlapping) the plurality of second display units DA44 adjacent to the first display units (e.g., display units DA42_1 to DA42_ 4). Moreover, the sum of the sound emitting loudness of the sound emitting elements (such as SC44) corresponding to (or overlapping) the second display unit DA44 may be greater than the sum of the sound emitting loudness of the other sound emitting elements (such as SC45) corresponding to (or overlapping) the other display units DA45 in the sound emitting module SM. The loudness of the sound emitting elements (such as SC44) corresponding to (or overlapping) the second display unit DA44 is substantially equal, and the loudness of the other sound emitting elements (such as SC45) corresponding to (or overlapping) the other display units DA45 is substantially equal. In the present embodiment, the loudness emitted by the sound emitting elements (e.g., DA42_1 to DA42_4) corresponding to all the display units (e.g., DA42_1 to DA42_4, DA44 and DA45) in the display panel 510 is substantially equal to the total loudness of the sound emitting module SM.
Note that, in order to avoid the complexity of the drawing, in the display panel 510 of fig. 5, the display unit DA44 and the sound generating element SC44 corresponding thereto are only represented by a square indicated by a diagonal line. That is, each of the squares indicated by the right-diagonal lines in the display panel 510 can correspond to the display unit DA44 and the sounding element SC44, respectively. Similarly, in the display panel 510, the display unit DA45 and the sound emitting element SC45 corresponding thereto are indicated by only one square indicated by diagonal lines. That is, each of the squares of the display panel 510 represented by the left diagonal lines may correspond to the display unit DA45 and the sounding element SC45, respectively, but the embodiment of the invention is not limited to the display unit and the sounding element illustrated above.
Fig. 6 is a schematic diagram illustrating the allocation of voicing loudness for 2 voicing subjects in accordance with an embodiment of the invention. Referring to fig. 1 and fig. 6, the squares in the display panel 610 represent the display units DA 11-DANM in the display panel 110 and are arranged in a matrix of 4 × 6, but the embodiment of the invention is not limited thereto. In the present embodiment, when 2 sound objects SO51 and SO52 appear on the display screen, the sound object SO51 overlaps the display units DA51_1 to DA51_4, and the sound object SO52 overlaps the display units DA52_1 to DA52_ 4. Therefore, the sound loudness of the whole sound generation module SM can be respectively concentrated on the display units DA51_1 to DA51_4 and the display units DA52_1 to DA52_4, so that the sound generation elements (such as SC51_1 to SC51_4) corresponding to the display units DA51_1 to DA51_4 and the sound generation elements (such as SC52_1 to SC52_4) corresponding to the display units DA52_1 to DA52_4 can generate sound at the same time. Viewed from another aspect, in the present embodiment, the sound-generating objects (such as SO51 and SO52) in the display screen can generate sound across regional positions.
In this case, the total loudness of the sound generating module SM of the present embodiment may be substantially evenly distributed or distributed in a proportional relationship to the sound generating elements (e.g., SC51_1 to SC51_4) corresponding to (or overlapping) the display units DA51_1 to DA51_4 and the sound generating elements (e.g., SC52_1 to SC52_4) corresponding to (or overlapping) the display units DA52_1 to DA52_ 4. For example, the sound emitting elements (e.g., SC51_ 1-SC 51_4) corresponding to the display units DA51_ 1-DA 51_4 account for a% of the total loudness of the sound emitting module SM. Moreover, the sound emitting elements (e.g., SC52_1 to SC52_4) corresponding to the display units DA52_1 to DA52_4 account for B% of the total loudness of the sound emitting module SM. Wherein A may be substantially equal to or not equal to B, and A may be greater than or less than B. Moreover, the sum of the sound emitting loudness of the sound emitting elements (such as SC51_1 to SC51_4) corresponding to the display units DA51_1 to DA51_4 and the sound emitting elements (such as SC52_1 to SC52_4) corresponding to the display units DA52_1 to DA52_4 may be substantially equal to the total loudness of the sound emitting module SM.
Further, the sound emitting elements (e.g., SC51_1 to SC51_4) overlapping the display units DA51_1 to DA51_4 may respectively set the sound emitting loudness according to the area ratio of the display units DA51_1 to DA51_4 where the sound emitting object SO51 is located. Viewed from another aspect, a% of the total loudness of the sound emitting modules SM may be allocated to the corresponding sound emitting elements (e.g., SC51_1 to SC51_4) according to the area ratios in the display units DA51_1 to DA51_ 4. Further, a% is related to the area of the sound object SO51 and the area of the sound object SO 52. For example, a% — the area of the sound object SO 51/(the area of the sound object SO51 + the area of the sound object SO 52).
On the other hand, the sound emitting elements (e.g., SC52_1 to SC52_4) overlapped with the display units DA52_1 to DA52_4 may set the sound emitting loudness according to the area ratio of the display units DA52_1 to DA52_4 where the sound emitting object SO52 is located, respectively. Viewed from another aspect, B% of the total loudness of the sound emitting modules SM may be allocated to the corresponding sound emitting elements (e.g., SC52_1 to SC52_4) according to the area ratios in the display units DA52_1 to DA52_ 4. And, B% is related to the area of the sound object SO51 and the area of the sound object SO 52. For example, B% — the area of the sound object SO 52/(the area of the sound object SO51 + the area of the sound object SO 52).
Fig. 7 is a diagram illustrating allocation of voicing loudness when a voicing object moves to a different display unit, in accordance with an embodiment of the present invention. Referring to fig. 1 and fig. 7, the squares in the display panel 710 represent the display units DA 11-DANM in the display panel 110 and are arranged in a matrix of 4 × 6, but the embodiment of the invention is not limited thereto. When a single sound emission object SO61 appears in the display screen, since the sound emission object S61 only overlaps with the display unit DA61 (corresponding to the first display area), the sound emission loudness of the entire sound emission module SM can be concentrated on the sound emission element (e.g., SC61) overlapping with the display unit DA61, that is, the sound emission element (e.g., SC61) overlapping with the display unit DA61 is solely used for sound emission. Furthermore, when the sound generating object SO61 appearing on the display screen moves from the sound generating element (e.g., SC61) overlapped by the display unit DA61 to the sound generating element (e.g., SC62) overlapped by the display unit DA62, the present embodiment may determine the allocation of the sound generating loudness according to the state of the sound generating object SO62 on the display unit DA62, and perform the calculation according to the above-mentioned embodiments of fig. 2 to 6.
In this embodiment, the detection of the display frames can be performed at a rate of N display frames, where N is a positive integer. For example, the screen analysis may be performed once on two display screens (N ═ 2), or may be performed once on three display screens (N ═ 3), which depends on the user setting or the circuit design, but the embodiment of the present invention is not limited thereto.
Fig. 8 is a flowchart of a driving method of a sound emitting module according to an embodiment of the invention. Referring to fig. 8, in the present embodiment, the sound module has a plurality of sound elements, and the sound elements are correspondingly configured with a plurality of display units of the display panel in a one-to-one manner. In step S810, the image analysis circuit may analyze the position of the sound object in the display screen and provide sound information accordingly. In step S820, the display device may determine, through the sound driving circuit, a first display unit of the display units overlapping with the sound generating object according to the sound generating information, and adjust (e.g., increase) the loudness of the sound generating element corresponding to the first display unit.
The details of the steps are described in the foregoing embodiments and implementations, and are not repeated herein.
In summary, the display device of the present invention can generate sound from the sound generating object in the display screen through the plurality of sound generating elements in the display panel. Moreover, the display panel of the present invention can determine the distribution of the sound to each sound generating element according to the sound generating position of the sound generating object. Therefore, the display equipment can improve the telepresence and the viewing quality of a user during viewing.
The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
