In one embodiment, as shown in fig. 1 and 2, the embodiment of the present application provides a micro display 100, which includes a micro display chip 110 having a display area 111 and at least one acceleration sensor 112, and a controller 120, wherein the controller 120 is integrated in the micro display chip 110 or is disposed outside the micro display chip 110, the controller 120 includes a picture comparison circuit unit 121 and a picture correction circuit unit 122, the picture comparison circuit unit 121 is configured to receive primary picture information to be displayed, and is electrically connected to the display area 111, the at least one acceleration sensor 112, and the picture correction circuit unit 122, respectively, and the picture correction circuit unit 122 is further electrically connected to the display area 111.
It is understood that the micro display 100 according to the embodiment of the present application may be applied to a smart display device such as smart glasses to output screen information for displaying a corresponding smart display device through the display area 111 thereof. Thus, the above-mentioned primary screen information to be displayed is mainly transmitted to the screen comparing circuit unit 121 of the present micro display 100 by the controllers of these smart display devices. Since the acceleration sensor 112 is disposed on the micro display chip 110 simultaneously with the display area 111, it can determine whether the display area 111 is subject to shake by sensing whether the micro display chip 110 is subject to shake, and the number of the acceleration sensors 112 can be arbitrarily adjusted according to the actual detection accuracy. The above-mentioned picture comparison circuit unit 121 may be specifically configured to obtain primary picture information to be displayed and sensor information of at least one acceleration sensor 112, and directly output the primary picture information to be displayed to the display area 111 for corresponding picture display when no shake occurs in the display area 111, or analyze and obtain a picture shake condition (specifically may include a shake direction and a shake amplitude) of the primary picture information to be displayed according to the primary picture information to be displayed and the sensor information when shake occurs in the display area 111, and feed back the picture shake condition to the picture correction circuit unit 122. The above-mentioned picture correction circuit unit 122 is specifically configured to perform picture correction processing on the primary picture information to be displayed according to the picture jitter condition (this process may be specifically described as follows: after analyzing the direction and amplitude of the jitter, the picture correction circuit unit 122 generates an electric signal in an opposite direction according to these information to counteract the jitter in the original signal), so as to obtain and output the target picture information without jitter to the display area 111. In addition, the above-mentioned controller 120 is integrated in the micro display chip 110 or is disposed outside the micro display chip 110, and it is preferable to optionally integrate the controller 120 in the micro display chip 110, so that the degree of the micro display chip 110 can be further improved, so as to reduce the number of components of the micro display 100 disposed outside the micro display chip 110, and further reduce the occupied space of the micro display 100.
Thus, with the above configuration, when the acceleration sensor 112 detects the shake of the micro display chip 110 during the use of the smart display device equipped with the micro display 100, the picture comparison circuit unit 121 may obtain the primary picture information to be displayed in the display area 111 and the sensor information of at least one acceleration sensor 112, respectively, so as to analyze and obtain the picture shake of the primary picture information to be displayed. And according to the picture shaking situation, the picture correction processing is performed on the primary picture information to be displayed by the picture correction circuit unit 122, so that the target picture information without shaking is obtained and output and displayed by the display area 111. Meanwhile, since the above structure directly integrates the anti-shake detection structure (i.e., the acceleration sensor 112) into the micro-display chip 110, the complexity and cost of the respective manufacturing process are reduced, and the component structure of the intelligent display device equipped with the micro-display 100 is reduced, thereby increasing the convenience of the whole intelligent display device.
In some examples, as shown in fig. 1 and 2, the micro display 100 specifically further includes at least one position driving unit 130. At least one position driving unit 130 is respectively disposed outside the micro display chip 110, and each position driving unit 130 is disposed opposite to one side of the micro display chip 110 and is in driving connection with the opposite side of the micro display chip 110. The controller 120 further includes a position correction circuit unit 123, and the position correction circuit unit 123 is electrically connected to the at least one acceleration sensor 112 and the at least one position driving unit 130, respectively.
It is understood that the number of the above-mentioned position driving units 130 is mainly determined according to the number of sides of the micro display chip 110 and the position correction accuracy of the micro display chip 110. Preferably, a position driving unit 130 is disposed corresponding to each side of the micro display chip 110, so that when the direction of any side of the micro display chip 110 is jittered, the corresponding position driving unit 130 drives the micro display chip 110 to perform corresponding position change, so as to ensure that the picture displayed in the display area 111 on the micro display chip 110 is not jittered.
Thus, through the structural arrangement in this example, when the micro display chip 110 is detected to shake by the acceleration sensor 112 during the use process of the intelligent display device equipped with the micro display 100 of this embodiment of the present application, the micro display chip 110 is driven by the position driving unit 130 to perform corresponding position change, so as to reduce the shake situation of the micro display chip 110, and effectively improve the shake situation of the picture displayed in the display area 111 on the micro display chip 110.
In some examples, as shown in fig. 1, the micro display chip 110 includes a first side, a second side, a third side, and a fourth side disposed end to end in order, and the micro display 100 includes four position driving units 130. A position driving unit 130 is disposed opposite to the first side and is in driving connection with the first side. A position driving unit 130 is disposed opposite to the second side and is in driving connection with the second side. A position driving unit 130 is disposed opposite to the third side and is in driving connection with the third side. A position driving unit 130 is disposed opposite to the fourth side and is in driving connection with the fourth side. In this way, by the above configuration, when the direction of any side of the micro display chip 110 is jittered, the corresponding position driving unit 130 drives the micro display chip 110 to perform corresponding position change, so as to ensure that the picture displayed in the display area 111 on the micro display chip 110 is not jittered.
In some examples, as shown in fig. 1, the micro display 100 further includes four elastic structures 140, one position driving unit 130 is drivingly connected to the first side driving through one elastic structure 140, one position driving unit 130 is drivingly connected to the second side driving through one elastic structure 140, one position driving unit 130 is drivingly connected to the third side driving through one elastic structure 140, and one position driving unit 130 is drivingly connected to the fourth side driving through one elastic structure 140. In this way, the above structure can be used to make the elastic structure 140 not only make the corresponding position driving unit 130 act on the position of the corresponding side of the micro display chip 110. Meanwhile, when the micro display chip 110 shakes, the micro display chip 110 can be buffered, so that the shaking of the picture can be further reduced.
In some examples, as shown in fig. 1, the surface of the micro display chip 110 provided with the display area 111 is further provided with at least one interface definition area, which is located between the first side and the side of the adjacent display area 111 and/or between the second side and the side of the adjacent display area 111. When the controller 120 is integrated in the micro display chip 110, at least one interface definition area is electrically connected to the controller 120, and at least one position driving unit 130 is electrically connected to the controller 120 through at least one interface definition area. Or, when the controller 120 is disposed outside the micro display chip 110, the controller 120 is electrically connected to the display area 111 of the micro display chip 110 and the at least one acceleration sensor 112 through at least one interface definition area, that is, the picture comparison circuit unit 121 of the controller 120 is electrically connected to the at least one acceleration sensor 112 through at least one interface definition area, and the picture correction circuit unit 122 of the controller 120 is electrically connected to the display area 111 through at least one interface definition area. It is understood that the at least one interface definition area may be a pad interface definition area, and is formed by a row of metal pads (bonding pads). The number of the at least one interface definition area mentioned above may be correspondingly set according to the actual application requirement of the micro display chip 110, that is, one interface definition area may be set, or two interface definition areas may be set, or even three or more interface definition areas may be set, where at least one interface definition area shown in the figure includes a first interface definition area 113 and a second interface definition area 114, for example, the first interface definition area 113 may be specifically located between the first side and the side of the adjacent display area 111, and the second interface definition area 114 may be specifically located between the second side and the side of the adjacent display area 111. Thus, by the above configuration, the connection interface between the chip pins of the present micro-display chip 110 and the external circuit can be provided by the configuration of at least one interface definition area, and the signal transmission performance and the package layout of the present micro-display chip 110 are affected.
In some examples, as shown in fig. 1, at least one acceleration sensor 112 is respectively disposed on the surface of the micro display chip 110 where the display area 111 is disposed, and the at least one acceleration sensor 112 is respectively disposed between the first side and the side of an adjacent interface definition area (may be specifically the first interface definition area 113) and/or between the second side and the side of an adjacent interface definition area (may be specifically the second interface definition area 114). Taking the example that two acceleration sensors 112 are located between the second side and the side of the adjacent second interface defining area 114 as shown in fig. 1, the above structure may be used to arrange at least one acceleration sensor 112 on the surface of the micro-display chip 110 reasonably, so as to better determine whether the display area 111 shakes by sensing whether the micro-display chip 110 shakes.
In some examples, as shown in fig. 3, at least one acceleration sensor 112 is respectively disposed on the surface of the micro display chip 110 where the display area 111 is disposed, and the at least one acceleration sensor 112 is respectively located in at least one interface definition area (specifically, may be located in the first interface definition area 113 and/or located in the second interface definition area 114). Taking the example shown in fig. 2, two acceleration sensors 112 are respectively located in the first interface defining area 113 and the second interface defining area 114, that is, one acceleration sensor 112 is located in the first interface defining area 113 and is aligned with a plurality of metal pads of the first interface defining area 113 along the extending direction of the first side edge, and the other acceleration sensor 112 is located in the second interface defining area 114 and is aligned with a plurality of metal pads of the second interface defining area 114 along the extending direction of the second side edge. In this way, the above structure can be used to make at least one acceleration sensor 112 reasonably arranged on the surface of the micro-display chip 110, so as to better determine whether the display area 111 shakes by sensing whether the micro-display chip 110 shakes, and at the same time, further improve the screen duty ratio of the micro-display chip 100 (i.e. the area duty ratio of the display area 111 on the surface).
In some examples, as shown in fig. 4, at least one acceleration sensor 112 is respectively installed on other surfaces of the micro display chip 110 than the surface on which the display area 111 is provided or built in the micro display chip 110. As shown in fig. 3, an acceleration sensor 112 is provided on the surface on which the first side is located. In this way, the arrangement of the acceleration sensor 112 does not occupy the space on the surface where the display area 111 is arranged, so that at least one acceleration sensor 112 is reasonably arranged on the surface of the micro-display chip 110, so as to better determine whether the display area 111 shakes by sensing whether the micro-display chip 110 shakes, and further improve the screen occupation ratio of the micro-display chip 100 (i.e. the area occupation ratio of the display area 111 on the surface).
In some examples, as shown in fig. 5, the micro display 100 has four acceleration sensors 112, the four acceleration sensors 112 are respectively installed on the surface of the micro display chip 110 where the display area 111 is provided, and the four acceleration sensors 112 are respectively located on four corners of the micro display chip 110. In this way, the corresponding acceleration sensors 112 are disposed on the four corners of the micro-display chip 110, so that the corresponding acceleration sensors 112 can accurately detect the shake of any side of the micro-display chip 110, and whether the shake of the display area 111 occurs can be better determined by sensing whether the shake of the micro-display chip 110 occurs.
In some examples, as shown in fig. 1 to 5, the acceleration sensor 112 may be specifically any one of a capacitive acceleration sensor 112, a piezoresistive acceleration sensor 112, and a gyroscope, so as to better determine whether the display area 111 is dithered by sensing whether the micro-display chip 110 is dithered. Preferably, the acceleration sensor 112 may be specifically a gyroscope. Meanwhile, the acceleration sensor 112 may be combined with a CMOS fabrication process using a mature mes process to better integrate the acceleration sensor 112 on the micro display chip 110.
In one embodiment, the present application provides a smart display device, which may specifically include a device housing and the micro display 100 in the above embodiment, where the micro display 100 may specifically be mounted on the device housing, and the display area 111 of the micro display chip 110 is exposed on the surface of the device housing. The structure and function of the micro-display 100 are detailed above, and will not be described herein.
In this way, through the above configuration, when the acceleration sensor 112 detects the shake of the micro display chip 110 during the use process of the intelligent display device according to the embodiment of the present application, the image comparison circuit unit 121 may respectively obtain the primary image information to be displayed in the display area 111 and the sensor information of at least one acceleration sensor 112, so as to analyze and obtain the image shake condition of the primary image information to be displayed. And according to the picture shaking situation, the picture correction processing is performed on the primary picture information to be displayed by the picture correction circuit unit 122, so that the target picture information without shaking is obtained and output and displayed by the display area 111. Meanwhile, since the anti-shake detection structure (i.e., the acceleration sensor 112) is directly integrated into the micro-display chip 110, the complexity and cost of the respective manufacturing process are reduced, and the component structure of the intelligent display device is reduced, so that the overall convenience of the intelligent display device is improved.
In one embodiment, as shown in fig. 6, an embodiment of the present application provides a picture anti-shake method, which is specifically applicable to the micro display 100 of the above embodiment or the smart display device of the above embodiment, and includes the following steps:
step S110: the primary picture information to be displayed and the sensor information of at least one acceleration sensor are acquired by a picture comparison circuit unit.
Step S120: judging whether the display area shakes according to the sensor information, and analyzing and obtaining the picture shaking condition of the primary picture information to be displayed according to the primary picture information to be displayed and the sensor information when the display area shakes.
Step S130: and according to the picture jitter condition, carrying out picture correction processing on the primary picture information to be displayed through a picture correction circuit unit to obtain and output and display target picture information without jitter through a display area.
It can be understood that, as shown in fig. 1 to 5, when the micro display 100 or the intelligent display device according to the embodiment of the present application performs display, the micro display 100 or the intelligent display device may firstly obtain the primary picture information to be displayed and the sensor information of at least one acceleration sensor 112 through the picture comparison circuit unit 121, then determine whether the display area 111 shakes according to the sensor information, if the surrounding environment does not cause the micro display 100 or the intelligent display device to shake, that is, determine that the display area 111 does not shake according to the sensor information, then directly output the primary picture information to be displayed to the display area 111 through the picture comparison circuit unit 121 for performing corresponding picture display, and if the surrounding environment causes the micro display 100 or the intelligent display device to shake, that is, determine that the display area 111 shakes according to the sensor information, then further analyze and obtain the picture shake condition of the primary picture information to be displayed according to the primary picture information and the sensor information, and feed the picture shake condition back to the picture correction circuit unit 122. Finally, according to the picture jitter condition, the picture correction processing is performed on the primary picture information to be displayed through the picture correction circuit unit 122, so as to obtain and output and display the target picture information without jitter through the display area 111.
In this way, by the image anti-shake method according to the embodiment of the present application, when the micro display 100 of the above embodiment or the intelligent display device of the above embodiment performs image display, the influence of shake of the micro display 100 or the intelligent display device is avoided as much as possible, so as to effectively solve the technical problem that the conventional intelligent display device such as intelligent glasses is easy to shake in the use process, so that the image is unclear.
