[0037] AsFigure 1 as shown, Figure 1 The structure schematic diagram of the dynamic image display device 100 disclosed by some embodiments of the utility model, a dynamic image display device 100 includes frame 101, and the close-range display device 102 arranged in the inside of frame 101, the long-range display device 103 arranged at the edge of frame 101, still include control module 104, control module 104 is electrically connected with close-range display module 102 and long-range display module 103 respectively, and control module 104 is used to send display signal to close-range display module 102 or long-range display module 103 to show dynamic image.

[0038] Optionally, the shape of frame 101 includes rectangle, circle and the like, the shape of frame is not limited in the utility model, in actual use, can be flexibly selected according to actual use demand and visual aesthetic feeling and the like requirements in many aspects.Such as Figure 1 The shape of frame 101 in the utility model is rectangle.The material of frame 101 can select metal, composite material and the like, preferably, the material of frame 101 selects high-strength and light-weight material according to actual use demand, and cost is reduced as far as possible.

[0039] Optionally, control module 104 and close-range display module 102 and long-range display module 103 are connected through wire 105 respectively.

[0040] Optionally, long-range display module 103 is arranged at the edge position of frame 101, and the position of the setting at least guarantees that the central position at target distance can show dynamic image, to make the observer see dynamic image in the central position.The observation effect of dynamic image is best when long-range display module 103 is arranged at the edge position of frame 101 in the process of strabismus measurement, and the observer observes dynamic image, avoids the measurement error due to distance angle and the like offset, to improve the precision of strabismus measurement.

[0041] Preferably, long-range display module 103 can also be arranged at the edge position of frame 101 that satisfies other requirements, such as the dynamic image is displayed at multiple positions (can show dynamic image completely at target distance) of target distance, then long-range display module 103 can be arranged at other positions of the edge of frame 101.Such as can be arranged at the upper edge, lower edge, left edge and right edge of frame 101, and the number is not strictly limited, but it needs to be noted that the problem that the image displayed by long-range display module 103 at a distance cannot be overlapped or displayed incompletely.

[0042] Optionally, the displayed dynamic image contains dynamic visual targets of multiple visual elements, not limited to changes in shape, pattern, color, etc., such as motion trajectory patterns, flickering change patterns, fusion scene patterns, etc., which can provide a rich and colorful image compared to a single image (such as a static dot icon with only black and white colors), and can achieve targeted observation when facing different patients.

[0043] The near-view display module 102 and the far-view display module 103 provided by the dynamic image display device 100 cooperate with the control module 104 to flexibly adjust the distance between the observer and the dynamic image display device 100, and to improve the observer's attention by providing a rich and colorful dynamic image, thereby meeting the diverse needs of different observers for display distance and image.

[0044] In a specific example, during the strabismus measurement process, when the observer needs to observe a dynamic image in the near view, the control module 104 sends a display signal to the near-view display module 102 to display the dynamic image on the near-view display module 102, and when the observer needs to observe a dynamic image in the far view, the control module 104 sends a display signal to the far-view display module 103 to display the dynamic image on the far-view display module 103, thereby flexibly adjusting the distance between the observer and the dynamic image display device 100 according to the different needs of the observer. The displayed dynamic image is a dynamic color pattern, which is much more attractive to the observer, especially children or people with difficulty concentrating, than a static dot image, thereby improving the observer's concentration during the measurement process, and thereby improving the accuracy of the strabismus measurement result as a whole.

[0045] According to some embodiments of the present application, the far-view display module 103 includes a laser source connected to the control module 104, and the laser source is used to project a dynamic image to a position at a first distance from the near-view display module 102 for display after receiving a display signal. The first distance can be flexibly set according to the different needs of the observer to display a dynamic image at a relatively far position, thereby meeting the requirements of different observers for display distance. Optionally, the laser source is connected to the control module 104 through the wire 105.

[0046] According to some embodiments of the present application, please refer to Figures 1-2 , Figure 2Another structural schematic view of the dynamic image display device 100 disclosed by some embodiments of the utility model discloses another structural schematic view of the dynamic image display device 100, and the dynamic image display device 100 still includes the long-range display adaptation module 106 set at the first distance from the close-range display module 102, and the long-range display adaptation module 106 is used to display the dynamic image projected by the laser source.It can be understood that the long-range display adaptation module 106 cooperates with the long-range display module 103 to meet the requirement of displaying the dynamic image at a suitable distance far away.The long-range display adaptation module 106 cooperates with the laser source of the long-range display module 103, is set at the position of the first distance from the close-range display module 102, and displays the dynamic image more completely, and under the condition of meeting the requirement of the long-range display of the observer, the experience of the observation of the long-range image of the observer can be further improved.

[0047] According to some embodiments of the utility model, please refer to Figures 1-2 The position of the laser source at the edge of the frame 101 is adapted to the first distance and the center height of the long-range display adaptation module 106.It can be understood that the position of the laser source at the edge of the frame 101 is adapted to the first distance and the center height of the long-range display adaptation module 106, so that the dynamic picture can be displayed as far as possible in the center position of the long-range display adaptation module 106, and the best observation effect is provided for the observer.

[0048] According to some embodiments of the utility model, please refer to Figures 1-2 The long-range display adaptation module 106 includes a curtain or an LED screen.No matter the curtain or the LED screen as the long-range display adaptation module 106 can provide a larger display size, has higher resolution, and can better display the dynamic image, for example, for some dynamic images with rich colors and more shape changes, better display effect can also be exhibited.

[0049] According to some embodiments of the utility model, please refer to Figures 1-2 The close-range display module 102 and the frame 101 are mutually embedded.As the close-range display module 102 is set in the frame 101, they are mutually embedded, so that the space can be effectively utilized to the maximum extent, and in the overall layout of the clinometer or other related display devices, extra space is avoided, so that the whole equipment is more compact.

[0050] According to some embodiments of the utility model, please refer to Figures 1-2The inner four peripheral edges of the frame 101 are provided with grooves, and the outer four peripheral edges of the close-range display module 102 are provided with protruding strips, and the sizes of the grooves and the protruding strips are matched. Preferably, the four peripheral edges in the frame 101 are accurately designed with grooves, which are regular in shape and uniform in depth, and the outer four peripheral edges of the close-range display module 102 are correspondingly provided with protruding strips matched in size, which are smooth in surface and stable in structure. In the assembly process, the matching structures of the two greatly simplify the installation process of the close-range display module 102 and the frame 101, and only need to slide the protruding strips along the grooves, so that quick and accurate positioning and installation can be realized, and the production and assembly efficiency is effectively improved. During the use of the equipment, this closely fitted mode can ensure that the close-range display module 102 remains highly stable in the frame 101, and even if a certain degree of vibration, shaking or collision is encountered, displacement or loosening will not easily occur.

[0051] According to some embodiments of the present application, please refer to Figures 1-2 The close-range display module 102 includes a screen. Since the screen is close to the observer, it can clearly display image details with high pixel density. For example, during the strabismus measurement process, when displaying a test chart or a dynamic pattern, the screen can accurately present the fine outlines and lines of letters, numbers and graphics, so that the myopic patient can more accurately distinguish.

[0052] According to another aspect of the present application, as shown in Figure 3 A strabismus measuring instrument 300 is also provided, which comprises a main body 200 and a dynamic image display device 100 as described in any one of the above, the frame 101 of the dynamic image display device 100 is connected with the main body 200, and the frame 101 can rotate around the edge connecting the frame 101 and the main body 200. For example, when the observer needs to observe the dynamic image close to the observer, the frame 101 is rotated to the first unfolded position to provide the dynamic image close to the observer for the observer, and when the observer needs to observe the dynamic image far away from the observer, the frame 101 is rotated to the second unfolded position to provide the dynamic image far away from the observer for the observer. The frame 101 can rotate freely around the edge connecting the frame 101 and the main body 200 between the first unfolded position and the second unfolded position. Preferably, the frame 101 can rotate 180° around the edge connecting the frame 101 and the main body 200 between the first unfolded position and the second unfolded position.

[0053] Optionally, the frame 101 is flipped and fixed between the first unfolded position and the second unfolded position by a female bayonet joint, a magnetic attraction, a rotating shaft provided with a rotating limiting structure 201 or the like. For example Figure 4 as shown, Figure 4The schematic view of the rotation limiting structure 201 provided for some embodiments of the utility model, the frame 101 realizes rotation and fixing between the first unfolding position and the second unfolding position through the rotation limiting structure 201 around the side connected with the main body 200. The rotation limiting structure 201 includes spring column 202 and limiting sleeve 203, and both of them work cooperatively to realize specific limiting function. The spring column 202 is installed in the concave groove 204 on the frame 101, and the concave groove 204 and the frame 101 adopt the design of integral molding, which not only enhances the integrity and stability of the structure, but also simplifies the process link of production and manufacturing to a certain extent. The limiting sleeve 203 is tightly sleeved on the frame 101, and the frame 101 can rotate circumferentially relative to the limiting sleeve 203, and this rotation freedom degree lays the foundation for subsequent screen turnover positioning. The limiting sleeve 203 is symmetrically provided with two limiting grooves 205 on the end face close to the free end of the spring column 202. The position and size of the two limiting grooves 205 are matched with the clamping action of the spring column 202. The spring column 202 includes a cylindrical top head 206, a spring and a sleeve seat. The cylindrical top head 206 has a hollow cavity embedded in the axial direction from one end face, and the spring is sleeved in the hollow cavity of the cylindrical top head 206. The sleeve seat cooperates with the cylindrical top head 206, and one end thereof is in a closed state. Under the action of the spring force, the cylindrical top head 206 can slide axially along the sleeve seat to realize turnover positioning of the frame 101. The free end of the cylindrical top head 206 can be selectively clamped in the two limiting grooves 205, and when clamping occurs, the frame 101 can be stably turned and stayed at the first unfolding position or the second unfolding position. Specifically, in the process of turning the frame 101 to the second unfolding position, the spring column 202 will turn synchronously with the frame 101 due to the circumferential limiting action of the concave groove 204. In this turning process, the cylindrical top head 206 will slide out of one of the limiting grooves 205, then move smoothly along the end face of the limiting sleeve 203 until accurately slide into the other limiting groove 205, the whole process is smooth and accurate, effectively ensures the stability and reliability of the frame 101 when switching between different unfolding positions, and provides a solid structural guarantee for the normal operation and operation experience of the strabismus measuring instrument 300.

[0054] The above embodiments describe the dynamic image display device 100 and the strabismus measuring instrument 300 of the utility model in detail, and thus the embodiments of the present disclosure have been described in detail. In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein according to the above description.
