Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0029] In one embodiment, as shown in Figures 1 and 2, the embodiment of the present application provides a microdisplay 100, including a microdisplay chip 110 having a display area 111 and at least one acceleration sensor 112, and a controller 120. The controller 120 is integrated in the microdisplay chip 110 or installed outside the microdisplay 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 used to receive primary picture information to be displayed, and is electrically connected to the display area 111, at least one acceleration sensor 112 and the picture correction circuit unit 122, respectively. The picture correction circuit unit 122 is also electrically connected to the display area 111.

[0030] It is understandable that the microdisplay 100 mentioned in the embodiment of the present application can be used in smart display devices such as smart glasses to output and display the screen information of the corresponding smart display device through its display area 111. Therefore, the primary screen information to be displayed mentioned above is mainly sent by the controller of these smart display devices to the screen comparison circuit unit 121 of the microdisplay 100. Since the acceleration sensor 112 mentioned above is set on the microdisplay chip 110 at the same time as the display area 111, it can determine whether the display area 111 is shaking by sensing whether the microdisplay chip 110 is shaking. At the same time, the number of acceleration sensors 112 set can be arbitrarily adjusted according to the actual detection accuracy requirements. The aforementioned image comparison circuit unit 121 can be specifically configured to respectively obtain the primary image information to be displayed and the sensor information of at least one acceleration sensor 112, and when no jitter occurs in the display area 111, directly output the primary image information to be displayed to the display area 111 for corresponding image display. Alternatively, when jitter occurs in the display area 111, the image jitter condition of the primary image information to be displayed (which may include the direction and amplitude of the jitter) is analyzed based on the primary image information to be displayed and the sensor information, and the image jitter condition is fed back to the image correction circuit unit 122. The aforementioned image correction circuit unit 122 can be specifically configured to perform image correction processing on the primary image information to be displayed based on the image jitter condition (this process can be specifically as follows: after analyzing the direction and amplitude of the jitter, the image correction circuit unit 122 generates an electrical signal in the opposite direction based on this information to offset the jitter in the original signal), thereby obtaining and outputting target image information without jitter to the display area 111. In addition, the controller 120 mentioned above is integrated into the microdisplay chip 110 or installed outside the microdisplay chip 110. Preferably, the controller 120 can be integrated into the microdisplay chip 110. In this way, the degree of the microdisplay chip 110 can be further improved to reduce the number of components in the microdisplay 100 that are arranged outside the microdisplay chip 110, so that the space occupied by the microdisplay 100 is further reduced.

[0031] In this way, through the above-mentioned structural setting, during the use of the intelligent display device equipped with the above-mentioned microdisplay 100, when the acceleration sensor 112 detects that the microdisplay chip 110 is shaking, the image comparison circuit unit 121 can 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 to analyze and obtain the image jitter of the primary image information to be displayed. And according to the image jitter, the image correction circuit unit 122 performs image correction processing on the primary image information to be displayed, and obtains and outputs the target image information without jitter through the display area 111. At the same time, because the above-mentioned structure directly integrates the anti-shake detection structure (i.e., the acceleration sensor 112) into the microdisplay chip 110, the complexity and cost of the separate manufacturing processes are reduced, and the component structure of the intelligent display device equipped with the microdisplay 100 is reduced, thereby increasing the overall convenience of the intelligent display device.

[0032] In some examples, as shown in Figures 1 and 2, the microdisplay 100 further includes at least one position drive unit 130. Each position drive unit 130 is disposed outside the microdisplay chip 110, with each position drive unit 130 positioned facing a side of the microdisplay chip 110 and drivingly connected to the facing side of the microdisplay chip 110. The controller 120 further includes a position correction circuit unit 123, which is electrically connected to the at least one acceleration sensor 112 and the at least one position drive unit 130.

[0033] It will be appreciated that the number of position drive units 130 mentioned above is primarily determined by the number of sides of the microdisplay chip 110 and the accuracy of position correction for the microdisplay chip 110. Preferably, a position drive unit 130 is provided for each side of the microdisplay chip 110. This ensures that if any side of the microdisplay chip 110 vibrates, a corresponding position drive unit 130 will drive the microdisplay chip 110 to adjust its position accordingly, thereby preventing the image displayed on the display area 111 of the microdisplay chip 110 from vibrating.

[0034] In this way, through the structural setting in this example, during the use of the intelligent display device equipped with the microdisplay 100 of the embodiment of the present application, when the acceleration sensor 112 detects that the microdisplay chip 110 is shaking, the position driving unit 130 will first drive the microdisplay chip 110 to make corresponding position changes to reduce the shaking of the microdisplay chip 110, so that the shaking of the picture displayed in the display area 111 on the microdisplay chip 110 is effectively improved.

[0035] In some examples, as shown in FIG1 , the microdisplay chip 110 includes a first side, a second side, a third side, and a fourth side that are sequentially arranged end to end, and the microdisplay 100 includes four position drive units 130. One position drive unit 130 is arranged opposite the first side and is drive-connected to the first side. One position drive unit 130 is arranged opposite the second side and is drive-connected to the second side. One position drive unit 130 is arranged opposite the third side and is drive-connected to the third side. One position drive unit 130 is arranged opposite the fourth side and is drive-connected to the fourth side. In this way, the above-mentioned structural arrangement can ensure that when any side of the microdisplay chip 110 is shaken, there is a corresponding position drive unit 130 to drive the microdisplay chip 110 to make a corresponding position change, so as to ensure that the image displayed in the display area 111 on the microdisplay chip 110 does not shake.

[0036] In some examples, as shown in FIG1 , the microdisplay 100 further includes four elastic structures 140, one position drive unit 130 is connected to the first side drive via an elastic structure 140, one position drive unit 130 is connected to the second side drive via an elastic structure 140, one position drive unit 130 is connected to the third side drive via an elastic structure 140, and one position drive unit 130 is connected to the fourth side drive via an elastic structure 140. In this way, the above-mentioned structural arrangement allows the elastic structure 140 to not only enable the corresponding position drive unit 130 to affect the position of the corresponding side of the microdisplay chip 110, but also to buffer the microdisplay chip 110 when the external environment causes the microdisplay chip 110 to shake, thereby further reducing the jitter of the image.

[0037] In some examples, as shown in FIG1 , the surface of the microdisplay chip 110 provided with the display area 111 is further provided with at least one interface definition area. The at least one interface definition area is located between a first side edge and an adjacent side edge of the display area 111 and / or between a second side edge and an adjacent side edge of the display area 111. When the controller 120 is integrated into the microdisplay chip 110, the at least one interface definition area is electrically connected to the controller 120, and the at least one position driving unit 130 is electrically connected to the controller 120 via the at least one interface definition area. Alternatively, when the controller 120 is external to the microdisplay chip 110, the controller 120 is electrically connected to the display area 111 and the at least one accelerometer 112 of the microdisplay chip 110 via the at least one interface definition area. Specifically, the image comparison circuit unit 121 of the controller 120 is electrically connected to the at least one accelerometer 112 via the at least one interface definition area, and the image correction circuit unit 122 of the controller 120 is electrically connected to the display area 111 via the at least one interface definition area. It can be understood that at least one interface definition area can be specifically a pad interface definition area, which is composed of a row of metal bonding pads. The number of the at least one interface definition area mentioned above can be set accordingly according to the actual application requirements of the micro display chip 110, that is, one interface definition area can be set or two interface definition areas can be set, or even three or more interface definition areas can be set. Taking the at least one interface definition area shown in the figure as an example, including the first interface definition area 113 and the second interface definition area 114, the first interface definition area 113 can be specifically located between the first side and the side of the adjacent display area 111, and the second interface definition area 114 can be specifically located between the second side and the side of the adjacent display area 111. In this way, through the above-mentioned structural setting, a connection interface between the chip pins of the present micro display chip 110 and the external circuit can be provided through the setting of at least one interface definition area, and it affects the signal transmission performance and packaging layout of the present micro display chip 110.

[0038] In some examples, as shown in FIG1 , at least one accelerometer 112 is mounted on the surface of the microdisplay chip 110 where the display area 111 is located, and at least one accelerometer 112 is located between a first side edge and a side edge of an adjacent interface definition area (specifically, the first interface definition area 113) and / or between a second side edge and a side edge of an adjacent interface definition area (specifically, the second interface definition area 114). For example, in FIG1 , where both accelerometers 112 are located between the second side edge and a side edge of the adjacent second interface definition area 114, the above-described structural arrangement allows the at least one accelerometer 112 to be rationally arranged on the surface of the microdisplay chip 110, thereby better detecting whether the display area 111 is vibrating by sensing whether the microdisplay chip 110 is vibrating.

[0039] In some examples, as shown in FIG3 , at least one accelerometer 112 is respectively mounted on the surface of the microdisplay chip 110 provided with the display area 111, and at least one accelerometer 112 is respectively located in at least one interface definition area (specifically, it may be located in the first interface definition area 113 and / or in the second interface definition area 114). Taking FIG2 as an example, in which two accelerometers 112 are respectively located in the first interface definition area 113 and the second interface definition area 114, that is, one accelerometer 112 is located in the first interface definition area 113 and is aligned with the plurality of metal pads of the first interface definition area 113 along the extension direction of the first side edge, and the other accelerometer 112 is located in the second interface definition area 114 and is aligned with the plurality of metal pads of the second interface definition area 114 along the extension direction of the second side edge. In this way, the above-mentioned structural setting can be used to reasonably arrange at least one acceleration sensor 112 on the surface of the micro-display chip 110, so as to better judge whether the display area 111 is shaking by sensing whether the micro-display chip 110 is shaking. At the same time, the screen-to-body ratio of the micro-display chip 100 (that is, the area ratio of the display area 111 to the surface) is further improved.

[0040] In some examples, as shown in FIG4 , at least one accelerometer 112 is mounted on a surface of the microdisplay chip 110 other than the surface on which the display area 111 is disposed, or is built into the microdisplay chip 110. As shown in FIG3 , one accelerometer 112 is disposed on the surface on which the first side edge is located. This allows the accelerometer 112 to no longer occupy the space on the surface on which the display area 111 is disposed, allowing the at least one accelerometer 112 to be rationally arranged on the surface of the microdisplay chip 110. This allows the microdisplay chip 100 to better detect whether the display area 111 is vibrating by sensing whether the microdisplay chip 110 is vibrating, thereby further improving the screen-to-body ratio (i.e., the area ratio of the display area 111 to the surface on which it is disposed) of the microdisplay chip 100.

[0041] In some examples, as shown in FIG5 , the microdisplay 100 has four accelerometers 112. The four accelerometers 112 are respectively mounted on the surface of the microdisplay chip 110 where the display area 111 is provided, and the four accelerometers 112 are respectively located at the four corners of the microdisplay chip 110. Thus, by providing corresponding accelerometers 112 at each of the four corners of the microdisplay chip 110, any vibration in the direction corresponding to any side of the microdisplay chip 110 can be accurately detected by the corresponding accelerometer 112. This allows for better determination of whether the display area 111 is vibrating by sensing whether the microdisplay chip 110 is vibrating.

[0042] In some examples, as shown in Figures 1 to 5 , the acceleration sensor 112 can be any one of a capacitive acceleration sensor 112, a piezoresistive acceleration sensor 112, and a gyroscope, to better sense whether the microdisplay chip 110 is vibrating and thereby determine whether the display area 111 is vibrating. Preferably, the acceleration sensor 112 can be a gyroscope. Furthermore, the acceleration sensor 112 can be fabricated using a mature MEMS process combined with a CMOS process to better integrate the acceleration sensor 112 on the microdisplay chip 110.

[0043] In one embodiment, the present application provides an intelligent display device. The intelligent display device may include a device housing and the microdisplay 100 described in the above embodiment. The microdisplay 100 may be mounted on the device housing, with the display area 111 of the microdisplay chip 110 exposed on the surface of the device housing. The structure and function of the microdisplay 100 are described above and will not be further described here.

[0044] In this way, through the above-mentioned structural setting, during the use of the intelligent display device of the embodiment of the present application, when the acceleration sensor 112 detects that the micro-display chip 110 is shaking, the image comparison circuit unit 121 can 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 to analyze and obtain the image jitter of the primary image information to be displayed. And according to the image jitter, the image correction circuit unit 122 performs image correction processing on the primary image information to be displayed, and obtains and outputs the target image information without jitter through the display area 111. At the same time, since the above-mentioned 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 separate manufacturing processes are reduced, and the component structure of the intelligent display device is reduced, thereby increasing the overall convenience of the intelligent display device.

[0045] In one embodiment, as shown in FIG6 , the present application provides an image stabilization method. The image stabilization method can be specifically applied to the micro display 100 of the above embodiment or the smart display device of the above embodiment. The image stabilization method includes the following steps:

[0046] Step S110 : obtaining primary image information to be displayed and sensor information of at least one acceleration sensor through an image comparison circuit unit.

[0047] Step S120: determining whether the display area is shaking according to the sensor information, and if shaking occurs in the display area, analyzing the image shaking of the primary image information to be displayed according to the primary image information to be displayed and the sensor information to obtain the image shaking condition.

[0048] Step S130: performing image correction processing on the primary image information to be displayed by the image correction circuit unit according to the image jitter condition, and obtaining and outputting target image information without jitter through the display area.

[0049] It can be understood that, as shown in Figures 1 to 5, when the microdisplay 100 or the intelligent display device of the embodiment of the present application is displayed, the microdisplay 100 or the intelligent display device will first obtain the primary screen information to be displayed and the sensor information of at least one acceleration sensor 112 through the screen comparison circuit unit 121, and then determine whether the display area 111 is shaking based on the sensor information. If the surrounding environment does not cause the microdisplay 100 or the intelligent display device to shake, that is, it is determined based on the sensor information that the display area 111 is not shaking, the primary screen information to be displayed is directly output to the display area 111 through the screen comparison circuit unit 121 for corresponding screen display. If the surrounding environment causes the microdisplay 100 or the intelligent display device to shake, that is, it is determined based on the sensor information that the display area 111 is shaking, then the screen jitter condition of the primary screen information to be displayed is further analyzed based on the primary screen information to be displayed and the sensor information, and the screen jitter condition is fed back to the screen correction circuit unit 122. Finally, according to the image jitter condition, the image correction circuit unit 122 performs image correction processing on the primary image information to be displayed, and obtains and outputs target image information without jitter through the display area 111 .

[0050] In this way, through the image stabilization method of the embodiment of the present application, the microdisplay 100 of the above embodiment or the smart display device of the above embodiment can be made to be less affected by the jitter of the microdisplay 100 or the smart display device as possible when displaying the image, so as to effectively improve the technical problem that the existing smart display devices such as smart glasses are prone to jitter during use, resulting in unclear images.
