Referring to fig. 1 and fig. 2, the display device 100 includes a display panel 110, a display manager 120, a sensing unit 130, an image compensation film 140, and a sound-emitting film 150. The sound emitting film 150 is disposed on the light emitting surface OS of the display panel 110 and vibrates according to the sound driving signal SP to emit sound.

The display manager 120 is electrically coupled to the sound emitting film 150, the image compensation film 140 and the sensing unit 130, and receives the sound signal AC, so as to drive the sound emitting film 150 according to the sound signal AC, that is, provide the sound driving signal SP to make the sound emitting film 150 emit a sound corresponding to the sound signal AC. Meanwhile, the display manager 120 determines that the image compensation film 140 operates in a first mode, a second mode or a third mode according to the state signal ST, wherein the vibration state of the image compensation film 140 is opposite to the vibration state of the sounding film 150 in the first mode, the vibration state of the image compensation film 140 is in phase with the vibration state of the sounding film 150 in the second mode, and the image compensation film 140 remains still in the third mode.
The Display Panel 110 is, for example, a Liquid Crystal Display (LCD), a Light-Emitting Diode (LED) Display Panel, an Organic Light-Emitting Diode (OLED) Display Panel, a Plasma Display Panel (PDP), a Field Emission Display (FED), or other types of Display panels.
In detail, taking the liquid crystal display panel as an example, the display panel 110 has a light emitting surface OS and a light incident surface IS, and the backlight module (not shown) provides an illumination beam LB with sufficient and uniform brightness to enter the light incident surface IS of the display panel 110, so that the display panel 110 can display an image IB, wherein the image IB IS emitted from the light emitting surface OS for a user to view.
In some embodiments, the display manager 120 may be a software program stored on a computer readable medium, such as a hard disk drive, a solid state drive, or the like. Before the display manager 120 is executed, it is loaded into a memory for a hardware device with computing capability, such as a Central Processing Unit (CPU), a Microprocessor (Microprocessor), etc. Alternatively, the display manager 120 may be accessible to hardware devices such as Application Specific Integrated Circuits (ASICs) and Programmable Logic Devices (PLDs).

The actuator/sensor 310 is disposed corresponding to a Black Matrix (Black Matrix) BM of the display panel 110, for example, in an area of the Black Matrix BM, or disposed directly above or below the Black Matrix BM, so as to avoid affecting the image IB. The actuator/sensor 310 may be at least one of the second actuator 160, the accelerometer, and the amplitude meter, that is, the second actuator 160 may be configured corresponding to the black matrix BM of the display panel 110, but the embodiment of the invention is not limited thereto.
Fig. 4 is a schematic view of a configuration of a sound-emitting membrane according to an embodiment of the invention. Referring to fig. 1 and 4, in the present embodiment, the sounding film 150 is, for example, a film covering the display panel 110. The actuator/sensor 410 is disposed corresponding to the black matrix BM of the display panel 110, but in other embodiments, the actuator/sensor 410 may also be disposed corresponding to the Fan-out area (Fan out area). The actuator/sensor 410 may be at least one of the first actuator 170, the accelerometer, and the amplitude meter, but the embodiment of the invention is not limited thereto. That is, the first actuator 170 is disposed corresponding to the black matrix BM and/or the fan-out region of the display panel 110.
In another embodiment, the sound generating film 150 may not cover a film of the display panel 110, but has a plurality of non-overlapping films, and each non-overlapping film corresponds to one of the pixels of the display panel 110, and the structure diagram thereof is similar to that of fig. 3, for example, each film of the sound generating film 150 is configured as the film 142 in fig. 3, and the actuator/sensor 410 is configured corresponding to the black matrix BM of the display panel 110, that is, the first actuator 170 may be configured corresponding to the black matrix BM of the display panel 110, which is similar to the actuator/sensor 310 shown in fig. 3. The description will not be repeated here.
Fig. 5 is a flowchart illustrating an operation method of a display device according to an embodiment of the invention, where the operation method of fig. 5 is applied to the display device 100 of fig. 1 and 2, and the operation method of the display device of the embodiment is described in detail below with reference to various elements in the display device 100.
In step S510, the display manager 120 receives the sound signal AC and controls the first actuator 170 to drive the sound emitting film 150 to emit sound according to the sound signal AC. In step S520, the sensing unit 130 senses the vibration state of the sound-emitting membrane 150 and correspondingly provides a state signal ST.
In step S530, the display manager 120 (or a processor executing the display manager 120) receives the status signal ST from the sensing unit 130, and then determines at least one of the frequency, the amplitude and the loudness of the sound generating membrane 150 according to the status signal ST, and determines a vibration index VI according to the determined at least one of the frequency, the amplitude and the loudness of the sound generating membrane 150, the vibration index VI representing, for example, the vibration range of the sound generating membrane 150. Therein, the display manager 120 may be configured with a state detection unit (e.g., specific software or hardware) to determine the state (i.e., vibration range) of the sound-generating membrane 150.
In step S540, the display manager 120 determines that the image compensation film 140 operates in the first mode, the second mode or the third mode according to the vibration index VI. In the first mode, the display manager 120 determines compensation data according to the vibration range (i.e., the vibration index VI) of the sound-generating film 150, and the compensation data is provided to the second actuator 16 of the image compensation film 140 to adjust the displayed frame, thereby completing the compensation of the frame of the display panel 110. Wherein, the display manager 120 may configure a calibration unit (e.g., specific software or hardware) to perform the actions in the first mode.
In the second mode, the display manager 120 determines the amplification data according to the vibration range (i.e., the vibration index VI) of the sound-emitting film 150, and the amplification data is provided to the second actuator 16 of the image compensation film 140 to adjust the displayed frame, thereby enhancing the frame of the display panel 110. Wherein, the display manager 120 may configure an amplification unit (e.g., specific software or hardware) to perform the actions in the second mode.
Specifically, the display manager 120 compares the vibration index VI with the first threshold T1 and the second threshold T2 to determine the operation mode of the image compensation film 140. Here, the first threshold T1 and the second threshold T2 are ratios of the vibration range to the screen size of the display panel 110, but the present invention is not limited thereto.
For example, the first threshold T1 may be 1%, and when the vibration range indicated by the vibration indicator VI is less than or equal to 1% of the display screen, that is, when the vibration indicator VI is less than or equal to the first threshold T1, the screen vibration is negligible for the user, so the display manager 120 performs step S550 to determine that the image compensation film 140 operates in the third mode, that is, the display manager 120 does not actuate the second actuator 160, and the image compensation film 140 remains still and does not perform image compensation.
When the vibration indicator VI is between the first threshold T1 and the second threshold T2, the second threshold T2 is, for example, 10%, that is, when the vibration range is less than 10% but greater than 1% of the display screen, the screen vibration affects the viewing quality for the user, so the display manager 120 performs step S560, and the display manager 120 determines that the image compensation film 140 operates in the first mode for image compensation.
In the first mode, the display manager 120 may calculate the predicted vibration value of the sound-generating membrane 150 at the next time point according to the state signal ST to determine the compensation data, or determine the compensation data according to the state signal ST and the sound signal AC, but the calculation method of the compensation data is not limited in the present invention. The display manager 120 actuates the second actuator 160 according to the compensation data to make the vibration state of the image compensation film 140 opposite to the vibration state of the sounding film 150, so that the offset generated after the image IB passes through the vibrating sounding film 150 is compensated by the image compensation film 140 vibrating in opposite phase through the interference principle.
When the vibration indicator VI is greater than or equal to the second threshold T2, for example, the vibration range is greater than 10% of the display frame, and the frame vibration is very strong for the user, which indicates that the display frame may be a very violent or shocked scene, such as an explosion, a rollover, a car accident, or a strong video scene when the video game is played and amplified, so the display manager 120 executes step S570 to determine that the image compensation film 140 operates in the second mode to perform the video enhancement effect. After the display manager 120 calculates the compensation data according to the state signal ST or the sound signal AC, or at least both, the display manager 120 activates the second actuator 160 to make the vibration state of the image compensation film 140 in phase with the vibration state of the sound emission film 150, so as to enhance the audio impact strength.
In another embodiment, when the vibration index VI is greater than the second threshold T2, the display manager 120 may choose to execute step S580 to determine that the image compensation film 140 operates in the third mode, where the image compensation film 140 remains still and does not perform image compensation. When the vibration index VI is greater than or equal to the second threshold T2, the step S570 or S580 may be determined according to a user setting (i.e., a preset value) or external display information.
In other words, the display manager 120 may further receive external display information, which includes Extended Display Identification Data (EDID) and/or includes a film type, such as horror film, action film, or love film. The display manager 120 determines whether the image compensation film 140 operates in the first mode, the second mode, or the third mode according to the state signal ST and the external display information.
Fig. 6A is a block diagram and fig. 6B is a side view of a display device according to another embodiment of the invention. Referring to fig. 6A and 6B, the display device 100 'is substantially similar to the display device 100 described above, except that the display device 100' further includes an auxiliary sound-generating film 152. The auxiliary sound-generating film 152 IS disposed on the light incident surface IS of the display panel 110, that IS, the auxiliary sound-generating film 152 IS disposed on the other side of the display panel 110 relative to the sound-generating film 150, but the disposition position of the auxiliary sound-generating film 152 IS not limited thereto in the present invention, and in other embodiments, the auxiliary sound-generating film 152 may be disposed on the side of the display panel 110 or beside the sound-generating film 150.
The auxiliary sound generating film 152 is electrically coupled to the display manager 120 to be driven in synchronization with the sound generating film 150. For example, the sound-emitting film 150 may be a front speaker or a tweeter, and the auxiliary sound-emitting film 152 may be a rear speaker or a subwoofer, but is not limited thereto.
The display device 100' further includes a plurality of third actuators 172 electrically coupled between the display manager 120 and the auxiliary sound-generating film 152 for controlling the display manager 120 to drive the auxiliary sound-generating film 152 to generate sound. The specific implementation and configuration of the display device 100' can refer to the teaching of the previous embodiments, and will not be described herein.
In summary, the display device of the embodiment of the invention includes a sound emitting film disposed on the light emitting surface of the display panel, an image compensation film disposed between the display panel and the sound emitting film, a sensing unit for sensing the vibration state of the sound emitting film, and a display manager. The display manager judges whether the image compensation film operates in a first mode, a second mode or a third mode according to the state signal provided by the sensing unit, wherein the vibration state of the image compensation film is opposite to the vibration state of the sounding film in the first mode, the vibration state of the image compensation film is in the same phase with the vibration state of the sounding film in the second mode, and the image compensation film is kept still in the third mode. Therefore, the display image interference generated by the sounding film arranged in front of the display panel can be solved, the viewed video quality is improved, and the video impact effect can be even further enhanced.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
