[0043] Medical displays are important equipment in the field of medical imaging. They are mainly used to display medical images. They can replace film and enable doctors to "soft read films". However, during the use of medical displays, the performance of the LCD backlight will degrade over time, making the brightness of the display dim and the grayscale not in line with the DICOM (Digital Imaging and Communications in Medicine) standard. The DICOM standard is one of the technical indicators that medical displays must meet, namely medical digital imaging and communications. It defines a medical image format that can be used for data exchange with quality that meets clinical needs. DICOM is widely used in radiology, cardiovascular imaging, and radiology diagnostic equipment and has been widely used in other medical fields such as ophthalmology and dentistry.
[0044] When the brightness of a medical display dims and the grayscale does not meet the DICOM standard, the medical display usually needs to be calibrated using a luminance meter and corresponding software. Common calibration methods include manual calibration with an external luminance meter and automatic calibration with a built-in luminance meter.
[0045] Usually, medical monitors have been calibrated for DICOM before leaving the factory. The calibration process is to first measure the brightness grayscale curve of the monitor with a professional brightness tester, then use a computer to perform calculations and data processing according to the highest and lowest brightness of the screen and the calculation method of the DICOM curve, and then write the calibrated standard DICOM curve into the memory of the medical monitor for use in the use link.
[0046] In order to ensure the long-term stability of medical displays, the brightness and DICOM curves of medical displays must be tested and calibrated after a period of use.
[0047] like Figure 2 and 3 As shown, the medical display generally includes components such as a display module 100, a frame 200, and a sensor 300. The display module is used to display medical images. The sensor 300 is used to receive light signals. The frame 200 is used to fix the display module 100 and the sensor 300. The sensor 300 can be slidably arranged in the frame 200 and can move relative to the display module 100. When the medical display is performing normal display, the sensor is located in the frame 200. When the medical display performs DICOM calibration, at least part of the area of the display module 100 displays a test pattern. At least part of the structure of the sensor 300 (at least including the photosensitive part for receiving the light signal) extends from the frame 200 and aligns with the area of the display module 100 for displaying the test pattern, and then retracts into the frame 200. At this time, the sensor 300 receives the test pattern displayed by the display module 100. The controller compares the information received by the sensor 300 with the standard DICOM curve written into the memory of the medical display, and then adjusts the display module 100 according to the comparison information. It should be noted that the test pattern is clearly different from the medical image.
[0048] This will lead to the following problems: First, the mechanical transmission structure is required to drive the movement of the sensor 300. On the one hand, the mechanical transmission structure is prone to damage. On the other hand, since the mechanical transmission structure has a certain thickness and needs to occupy a certain space in the frame, the thickness of the frame 200 is increased. Second, during the detection, the display module 100 needs to display the test pattern. In this way, during the measurement, at least part of the display module 100 needs to display the test pattern. In other words, the display module 100 cannot fully display the medical image.
[0049] like Figure 1As shown, the present application provides a medical display, including: a display module 100, a frame 200 and a sensor 300, wherein the display module 100 includes a normal light-emitting area 110 and an auxiliary light-emitting area 120, and the auxiliary light-emitting area 120 is arranged on one side of the normal light-emitting area 110; the frame 200 fixes the display module 100, and the frame 200 includes a fixed area 240, and the fixed area 240 is projected along the thickness direction to at least partially cover the auxiliary light-emitting area 120; the sensor 300 is arranged in the fixed area 240 and is opposite to the auxiliary light-emitting area 120, and the sensor 300 is used to receive the light signal emitted by the auxiliary light-emitting area 120.
[0050] The present application sets up an auxiliary light-emitting area 120 and fixes the sensor 300 on the frame 200 and faces the auxiliary light-emitting area 120. During normal display, the auxiliary light-emitting area 120 does not display the picture, and the normal light-emitting area 110 is used normally; when DICOM calibration is required, the auxiliary light-emitting area 120 displays the test pattern, and the sensor 300 calibrates the normal light-emitting area 110 after receiving it.
[0051] In this way, the setting of a mechanical transmission structure can be avoided, and the problem of damage to the mechanical transmission structure itself and the thickness of the frame 200 caused by the setting of the mechanical transmission structure can be avoided. At the same time, it also avoids the need to replace the original display area with a test pattern during detection, so that the existing normal light-emitting area 110 can be used normally, and it also avoids causing the sensor 300 to move under the drive of the mechanical transmission structure.
[0052] In addition, the sensor 300 is directly disposed toward the auxiliary light emitting area 120, which can ensure that the sensor 300 directly obtains the brightness information of the backlight source assembly 130. It can be understood that the sensor 300 is disposed toward the backlight source assembly 130 to directly obtain the information of the display module 100 without any information loss, so more precise adjustments can be made.
[0053] The above arrangement avoids the problem of low detection accuracy caused by arranging the sensor 300 on the side of the display module 100 and using the light guide unit to reflect the information on the display module 100 to the sensor 300 .
[0054] In this embodiment, based on the above description, the display module 100 includes a backlight source assembly 130, and the backlight source assembly 130 is arranged to extend from the normal light-emitting area 110 to the auxiliary light-emitting area 120, and the backlight source assembly 130 located in the light-emitting area and the auxiliary light-emitting area 120 is synchronously lit or extinguished. The backlight source assembly 130 includes a back plate 131 for supporting and balancing light, a light guide plate 132 for balancing light, a light source for emitting light, and a heat dissipation plate 133 and other components.
[0055] The present application preferably uses a whole piece of backlight source assembly 130. Through the above arrangement, the synchronization of lighting or extinguishing the backlight source assemblies located in the auxiliary light-emitting area and the normal light-emitting area can be ensured, so that the brightness of the auxiliary light-emitting area 120 can more accurately reflect the brightness of the normal light-emitting area 110 and the production cost of a whole piece of backlight source assembly 130 is lower, which has a cost advantage. Of course, in other embodiments, the backlight source assembly 130 can also be two backlight source units combined into one piece, and the two backlight source units are combined and laid in the normal light-emitting area 110 and the auxiliary light-emitting area 120. As long as the backlight source assemblies 130 located in the normal light-emitting area 110 and the auxiliary light-emitting area 120 are synchronously lit or extinguished, they should be within the protection scope of the present application.
[0056] In this embodiment, the sensor 300 is arranged toward the auxiliary light-emitting area 120, and is used to receive the brightness information of the backlight source assembly 130 in the auxiliary light-emitting area 120, and infer the brightness of the normal light-emitting area 110 according to the brightness information of the backlight source assembly 130 in the auxiliary light-emitting area 120. The reason is that since the backlight source assembly 130 located in the light-emitting area and the auxiliary light-emitting area 120 is synchronously lit or extinguished, the signal detected in the auxiliary light-emitting area 120 can well reflect the brightness information of the normal light-emitting area 110. In summary, the normal light-emitting area 110 can be adjusted according to the measured brightness information of the auxiliary light-emitting area 120.
[0057] When the backlight source assembly 130 is a whole block, the sensor 300 directly reads the brightness information of the backlight source assembly 130 located in the auxiliary light-emitting area 120, and directly adjusts the brightness of the entire backlight source assembly 130 according to the brightness information; when the backlight source assembly 130 is two backlight source units combined into one block, the sensor 300 reads the brightness information of the backlight source unit located in the auxiliary light-emitting area 120, and then synchronously adjusts the brightness of the two backlight source units according to the brightness information.
[0058] In this embodiment, based on the description of the backlight source assembly 130, the display module 100 also includes a display panel 140, which is disposed on the backlight source assembly 130, and the display panel 140 extends from the normal light-emitting area 110 to the auxiliary light-emitting area 120, and the sensor 300 is directed toward the display panel 140 located in the auxiliary light-emitting area 120 to receive a light signal emitted by the whole formed by the backlight source assembly 130 and the display panel 140.
[0059] Normal measurement of DICOM is to measure the light signal emitted by the whole formed by the backlight source assembly 130 and the display panel 140. When the sensor 300 receives the light signal emitted by the whole formed by the backlight source assembly 130 and the display panel 140, the DICOM curve of the normal light-emitting area 110 can be detected and corrected by comparison.
[0060] In this embodiment, reference Figure 4 The display panel 140 includes a first display unit 141 and a second display unit 142. The first display unit 141 is arranged in the normal light-emitting area 110, and the second display unit 142 is arranged in the auxiliary light-emitting area 120. The first display unit 141 and the second display unit 142 work synchronously or independently.
[0061] When the first display unit 141 is displayed normally, the second display unit 142 can be displayed synchronously with the first display unit 141. It is also possible that when the first display unit 141 is displayed normally, the second display unit 142 is displayed in black. When the first display unit 141 and the second display unit 142 are working and displaying synchronously, the second display unit 142 can expand the visual range of the first display unit 141 to a certain extent to obtain a better display effect. When the second display unit 142 displays a black screen, the second display unit 142 is integrated with the frame 200 from a visual point of view, so that a good visual effect can be obtained. In summary, the first display unit 141 and the second display unit 142 are displayed separately to adapt to a variety of situations.
[0062] Based on the above embodiment, the medical display includes a normal display state and a detection state; when the medical display is in the normal display state, the first display unit 141 is in a light-transmitting state, and the light emitted by the backlight source assembly 130 can be emitted outward through the first display unit 141; the second display unit 142 is in a light-shielding state, and the light emitted by the backlight source assembly 130 cannot be emitted through the second display unit 142; when the medical display is in the detection state, the second display unit 142 is in a light-transmitting state, and the light emitted by the backlight source assembly 130 can be emitted outward through the second display unit 142 and received by the sensor 300.
[0063] In the normal display state, the light emitted by the backlight source assembly 130 can be emitted outward through the first display unit 141, and at the same time, the light emitted by the backlight source assembly 130 cannot be emitted through the second display unit 142. In this way, the first display unit 141 displays normally to realize the predetermined function of the product, and when the second display unit 142 displays a black screen, it is integrated with the frame 200, and a good visual effect can be obtained.
[0064] In the detection state, the second display unit 142 is in a light-transmitting state, and the light emitted by the backlight source assembly 130 can be emitted outward through the second display unit 142 and received by the sensor 300. At this time, the operation of the second display unit 142 does not affect the normal operation of the first display unit 141.
[0065] In summary, whether in the normal display state or in the detection state, the normal operation of the first display unit 141 will not be affected, so that the normal use of the product will not be disturbed. Compared with the traditional detection method, the device of the present application can obtain a better use experience.
[0066] In another embodiment, if Figure 7 As shown, the display panel 140 is located in the normal light-emitting area 110, and there is no overlapping part between the projection of the display panel 140 on the backlight source assembly 130 and the projection of the auxiliary light-emitting area 120 on the backlight source assembly 130; the sensor 300 faces the backlight panel located in the auxiliary light-emitting area 120 to receive the light signal emitted by the backlight source assembly 130.
[0067] Since there is no overlap between the projection of the display panel 140 on the backlight assembly 130 and the projection of the auxiliary light-emitting area 120 on the backlight assembly 130, there is no display panel 140 in the auxiliary light-emitting area 120, and the sensor 300 receives the light signal emitted by the backlight assembly 130. Under this setting, the device can adjust the backlight assembly 130 of the normal light-emitting area 110 by detecting the backlight assembly 130 of the auxiliary light-emitting area 120, thereby obtaining a better display effect.
[0068] It should be noted that when the auxiliary light emitting area 120 is only provided with a backlight source assembly 130, the device measures the brightness of the backlight source assembly 130 for adjustment; when the auxiliary light emitting area 120 is provided with a backlight source assembly 130 and a display panel 140, the device measures the brightness and grayscale of the auxiliary light emitting area 120. Both measurement methods are embodiments of the present application and fall within the protection scope of the present application.
[0069] In this embodiment, according to Figure 5 As shown, the frame 200 includes a shading plate 210 located on a side of the display panel 140 away from the backlight assembly 130, and a minimum distance d1 from the edge of the shading plate 210 to the first display unit 141 is greater than or equal to 0.1 mm and less than or equal to 5 mm. Of course, in other embodiments, the minimum distance d1 may be only greater than or equal to 0.1 mm, or only less than or equal to 5 mm.
[0070] The applicant found in actual tests that a certain distance between the edge of the shading plate 210 and the first display unit 141 can leave a certain installation margin during installation, which is convenient for later installation. If no margin is set here or the margin is set very small, the shading plate 210 may cover the first display unit 141. If the reserved margin is too large, it will cause waste and the distance from the first display unit 141 is too large, which will cause unsightly appearance.
[0071] The applicant has found through a large number of experiments that when the minimum distance d1 from the edge of the shading plate 210 to the first display unit 141 is less than or equal to 0.1 mm, it will cause installation difficulties and it is easy to block the first display unit 141. When the minimum distance d1 from the edge of the shading plate 210 to the first display unit 141 is greater than or equal to 5, it will be wasteful and unsightly.
[0072] Preferably, the minimum distance from the edge of the shading plate 210 to the first display unit 141 is greater than or equal to 0.5 mm and less than or equal to 2 mm. The minimum distance from the edge of the shading plate 210 to the first display unit 141 is within a range of greater than or equal to 0.5 mm and less than or equal to 2 mm, which is a good range for installation. On the one hand, it will not cause installation difficulties and block the first display unit 141. On the other hand, it will not cause waste and is more beautiful.
[0073] In this embodiment, d1 is selected to be 1 mm, and in other embodiments, it can also be 1.2 mm, 1.5 mm, etc.
[0074] like Figure 5 As shown, the frame includes a shell 220; the shell 220 includes a fixing plate 221, the fixing plate 221 is located on the outside of the display module 100, the orthographic projection of the fixing plate 221 in the thickness direction is at least partially located on the auxiliary light-emitting area 120, and serves as the fixing area 240, and the sensor 300 is arranged on the fixing plate 221.
[0075] It should be noted that the fixing area 240 here is at least a partial structure of the fixing plate 221 , and at the same time, the shading plate 210 is the fixing plate 221 , or is at least a partial structure of the fixing plate 221 .
[0076] At least part of the orthographic projection of the fixing plate 221 in the thickness direction is located on the auxiliary light-emitting area 120. The sensor 300 installed on the fixing plate 221 needs to face the display module 100 in the auxiliary light-emitting area 120. Therefore, the sensor 300 is arranged between the auxiliary light-emitting area 120 and the fixing plate 221 and faces the display module 100, that is, the sensor 300 is completely blocked by the fixing plate 221. In this way, the user cannot see the sensor 300 from the outside, realizing a hidden design, maintaining the beauty of the device while also realizing the detection function.
[0077] In this embodiment, the fixing plate 221 is arranged in parallel with the display module 100. The fixing plate 221 is arranged in parallel with the display module 100 to ensure that the sensor 300 fixed on the fixing plate 221 faces the display module 100 to collect the optical signal of the display module 100. The sensor 300 faces the display module 100 to better receive the optical signal of the display module 100, and the fixing plate 221 is arranged in parallel with the display module 100 to ensure that the appearance is exquisite and consistent.
[0078] It should also be noted that, in this embodiment, an auxiliary shell 230 is further provided. The auxiliary shell 230 is provided in the outer shell 220 . The auxiliary shell 230 cooperates with the outer shell 220 to fix the display module 100 .
[0079] In another embodiment, according to Figure 6 As shown, the frame 200 includes a housing 220 and an auxiliary housing 230, the auxiliary housing 230 includes an extension unit 231 and a fixing unit 232 connected to each other, the extension unit 231 is arranged in the housing 220, and the fixing unit 232 is exposed outside the housing 220. The orthographic projection of the fixing unit 232 in the thickness direction is at least partially located on the auxiliary light-emitting area 120, the fixing unit 232 serves as the fixing area 240, and the sensor 300 is arranged on the fixing unit 232.
[0080] It should be noted that, in this embodiment, the fixed area 240 is at least a partial structure of the fixed unit 232 , and the shading plate 210 can be understood as the fixed unit 232 , or the shading plate 210 can be understood as a combination of at least a portion of the fixed unit 232 and the frame 200 .
[0081] The extension unit 231 is disposed in the housing 220 and connected to the fixing unit 232 , and supports the fixing unit 232 , so that the sensor 300 does not need to be disposed on the housing 220 , but only needs to be disposed on the fixing unit 232 of the auxiliary housing 230 .
[0082] Furthermore, the fixing unit 232 is arranged in parallel with the display module 100. The fixing unit 232 is arranged in parallel with the display module 100 to ensure that the sensor 300 fixed on the fixing unit 232 is facing the display module 100 to collect the light signal of the display module 100. At the same time, the fixing unit 232 is arranged in parallel with the display module 100 to ensure that its appearance is exquisite and consistent. Under normal circumstances, the part of the housing 220 facing the user is also arranged in parallel with the display module 100, which can further ensure the beauty of its appearance.
[0083] In this embodiment, the display module 100 includes a plurality of pixels, each pixel includes a sub-pixel unit displaying a different color; the detection range of the sensor 300 in the light-emitting layer covers all the sub-pixel units in at least one pixel.
[0084] The sensor 300 faces the display module 100 and needs to collect complete pixels. If only the content of the sub-pixel unit is collected, it will affect the detection effect. The detection range of the sensor 300 in the light-emitting layer covers all sub-pixel units in at least one pixel, which can avoid collecting at least one complete pixel for analysis when receiving the pixel, so that the measurement result can be obtained more accurately.
[0085] In this embodiment, please refer to Figure 8 , the angle between the sensor 300 and the edge of the auxiliary light-emitting area 120 is greater than or equal to 100° and less than or equal to 180°.
[0086] The applicant has found through a large number of experiments that when the edge angle α between the sensor 300 and the auxiliary light-emitting area 120 is less than or equal to 100°, the number of pixels of the display module 100 included in the sensor 300 is insufficient for detection, and when the edge angle α between the sensor 300 and the auxiliary light-emitting area 120 is greater than or equal to 180°, the display module 100 is infinitely long. Preferably, the edge angle α is selected to be 150° in this application. When the edge angle α is 150°, it can well include enough measurement pixels and ensure the length of the display module 100. In other embodiments, 120° or 140° can also be selected.
[0087] Please refer to Figure 8 The minimum distance between the sensor 300 and the display module 100 is greater than or equal to 0.2 mm and less than or equal to 5 mm.
[0088] The applicant has also found through a large number of experiments that when the minimum distance d between the sensor 300 and the display module 100 is less than or equal to 0.2 mm, the number of pixels that the sensor 300 can accept is insufficient for detection, and when the minimum distance d between the sensor 300 and the display module 100 is greater than or equal to 5 mm, the frame 200 that fixes the sensor 300 will be too thick, resulting in an unsightly appearance. Preferably, the minimum distance d between the sensor 300 and the display module 100 is greater than or equal to 0.5 mm and less than or equal to 2 mm. Within this range, the sensor 300 can obtain enough pixels for measurement and ensure the thickness of the frame 200.
[0089] Please refer to Figure 8The minimum distance between the edge of the orthographic projection of the sensor 300 on the display module 100 and the edge of the auxiliary light-emitting area 120 is greater than or equal to 0.2 mm and less than or equal to 8 mm.
[0090] Furthermore, the applicant has also found that when the minimum distance d2 between the edge of the orthographic projection of the sensor 300 on the display module 100 and the edge of the auxiliary light-emitting area 120 is less than or equal to 0.2 mm, the number of pixels that the sensor 300 can accept is insufficient for detection, and when the minimum distance d2 between the edge of the orthographic projection of the sensor 300 on the display module 100 and the edge of the auxiliary light-emitting area 120 is greater than or equal to 8 mm, the auxiliary light-emitting area 120 is too long. Preferably, when the minimum distance d2 between the edge of the orthographic projection of the sensor 300 on the display module 100 and the edge of the auxiliary light-emitting area 120 is greater than or equal to 0.866 mm and less than or equal to 3.4 mm, on the one hand, the sensor 300 can obtain enough pixels for measurement, and can also ensure that the length of the auxiliary light-emitting area 120 is not too long.
[0091] Please refer to Figure 8 The length from one end of the auxiliary light-emitting area 120 away from the normal light-emitting area 110 to the edge of the normal light-emitting area 110 is greater than or equal to 1 mm and less than or equal to 15 mm.
[0092] When the length d3 from one end of the auxiliary light-emitting area 120 away from the normal light-emitting area 110 to the edge of the normal light-emitting area 110 is less than or equal to 1 mm, the sensor 300 cannot obtain enough pixels for measurement, and when the length d3 from one end of the auxiliary light-emitting area 120 away from the normal light-emitting area 110 to the edge of the normal light-emitting area 110 is greater than or equal to 15 mm, the auxiliary light-emitting area 120 is too long. The applicant has found through a large number of experiments that when the length d3 from one end of the auxiliary light-emitting area 120 away from the normal light-emitting area 110 to the edge of the normal light-emitting area 110 is greater than or equal to 4 mm and less than or equal to 7.5 mm, on the one hand, the sensor 300 can obtain enough pixels for measurement, and can also ensure that the length of the auxiliary light-emitting area 120 is not too long.
[0093] In addition, the current main design plan for sensor 300 is to place it in a certain space at the edge of the entire machine. It can be placed at any position of the upper, lower, left, or right borders of the entire machine frame. The middle 2 / 3 area is preferred because the closer to the corners, the worse the brightness stability and uniformity will be.
