[0002] In recent years, affected by the epidemic situation at home and abroad, medical devices have developed rapidly. As an important interactive interface of medical devices, LCD panels have higher and higher requirements for the stability of display images in terminal applications. Medical display products can be divided into three categories: monitoring, diagnosis, and consultation and surgery products. Among them, diagnostic-grade display products have the most stringent requirements. In addition to the high standards for factory quality requirements, diagnostic displays also have strict requirements for image quality detection benchmarks during long-term use, such as regular brightness and curve correction. However, when the existing medical display is calibrated, the sensor pops out from the frame and aligns with the original display area. After the test pattern displayed on the original display area is received by the sensor, the sensor retracts into the frame. This will cause the following problems: a mechanical transmission structure is required to cooperate with the movement of the sensor. The mechanical transmission structure is prone to damage and increases the thickness of the frame.

[0041] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. Unless otherwise defined, technical or scientific terms used in this application should have the ordinary meaning understood by a person of ordinary skill in the art to which this invention belongs.

It will also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0042] Medical displays are essential equipment in the medical imaging field, primarily used to display medical images. They can replace film and enable doctors to "softly read" images. However, over time, the performance of the LCD backlight in medical displays degrades, causing the display's brightness to dim and grayscale to fail to meet the DICOM (Digital Imaging and Communications in Medicine) standard. The DICOM standard, one of the technical specifications medical displays must meet, stands for Digital Imaging and Communications in Medicine. It defines a medical image format for data exchange that meets clinical requirements. DICOM is widely used in radiology, cardiovascular imaging, and radiology diagnostic equipment, and is also gaining extensive application in other medical fields such as ophthalmology and dentistry.

[0043] When the brightness of a medical display dims and the grayscale does not comply with 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.

[0044] Medical displays are typically calibrated for DICOM before leaving the factory. The calibration process involves measuring the display's grayscale curve using a professional luminance meter. A computer then calculates the maximum and minimum brightness values ​​based on the screen's DICOM curve, performing calculations and data processing. The calibrated standard DICOM curve is then written to the medical display's memory for immediate use.

[0045] 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.

[0046] As shown in Figures 2 and 3, a 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 is 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 within the frame 200. When the medical display is performing DICOM calibration, at least a portion of the display module 100 displays a test pattern. At least a portion of the structure of the sensor 300 (including at least the photosensitive portion for receiving light signals) extends from the frame 200 and is aligned with the area of ​​the display module 100 used to display 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 obviously different from the medical image.

[0047] This leads to several problems: 1. A mechanical transmission structure is required to drive the movement of sensor 300. This is prone to damage, and because it is thick and occupies a certain amount of space within the frame, it increases the thickness of frame 200. 2. During testing, a test pattern must be displayed on display module 100. Therefore, at least a portion of display module 100 must display the test pattern during measurement. In other words, display module 100 cannot fully display the medical image.

[0048] As shown in Figure 1, the present invention 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.

[0049] This application provides an auxiliary light-emitting area 120 and fixes the sensor 300 to the frame 200, facing the auxiliary light-emitting area 120. During normal display, the auxiliary light-emitting area 120 does not display the image, and the normal light-emitting area 110 is used normally. When DICOM calibration is required, the auxiliary light-emitting area 120 displays a test pattern, and the sensor 300 receives it and calibrates the normal light-emitting area 110.

[0050] In this way, the need for a mechanical transmission structure can be avoided, thereby avoiding 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. 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.

[0051] In addition, the sensor 300 is set directly 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 when the sensor 300 is directed toward the backlight source assembly 130 and thus directly obtains information from the display module 100, there will be no information loss, so more precise adjustments can be made.

[0052] 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 .

[0053] In this embodiment, based on the above description, the display module 100 includes a backlight assembly 130. The backlight assembly 130 extends from the normal light-emitting area 110 to the auxiliary light-emitting area 120. The backlight assemblies 130 located in the light-emitting area and the auxiliary light-emitting area 120 are synchronously lit or extinguished. The backlight assembly 130 includes a backplate 131 for supporting and distributing light, a light guide plate 132 for distributing light, a light source for emitting light, and a heat dissipation plate 133.

[0054] The present application preferably uses a single backlight assembly 130. The above configuration ensures that the backlight assemblies in the auxiliary light-emitting area and the normal light-emitting area are lit or extinguished synchronously, thereby enabling the brightness of the auxiliary light-emitting area 120 to more accurately reflect the brightness of the normal light-emitting area 110. The production cost of a single backlight assembly 130 is lower, thus providing a cost advantage. Of course, in other embodiments, the backlight assembly 130 may also be a combination of two backlight units, with the two backlight units being arranged in the normal light-emitting area 110 and the auxiliary light-emitting area 120. As long as the backlight assemblies 130 in the normal light-emitting area 110 and the auxiliary light-emitting area 120 are lit or extinguished synchronously, they shall fall within the scope of protection of the present application.

[0055] In this embodiment, the sensor 300 is positioned toward the auxiliary light-emitting area 120 and is configured to receive brightness information from the backlight assembly 130 within the auxiliary light-emitting area 120. The brightness of the normal light-emitting area 110 is inferred based on the brightness information from the backlight assembly 130 within the auxiliary light-emitting area 120. This is because the backlight assembly 130 in the light-emitting area and the auxiliary light-emitting area 120 is synchronously turned on or off, so the signal detected in the auxiliary light-emitting area 120 can effectively reflect the brightness information of the normal light-emitting area 110. In summary, the normal light-emitting area 110 can be adjusted based on the brightness information measured in the auxiliary light-emitting area 120.

[0056] 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.

[0057] In this embodiment, based on the description of the above-mentioned backlight source assembly 130, the display module 100 also includes a display panel 140, which is arranged 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 facing the display panel 140 located in the auxiliary light-emitting area 120 to receive the light signal emitted by the whole formed by the backlight source assembly 130 and the display panel 140.

[0058] 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.

[0059] In this embodiment, referring to 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, and the first display unit 141 and the second display unit 142 work synchronously or independently.

[0060] When the first display unit 141 displays normally, the second display unit 142 can display synchronously with the first display unit 141. It is also possible that when the first display unit 141 displays normally, the second display unit 142 displays a black screen. When the first display unit 141 and the second display unit 142 work and display 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, visually the second display unit 142 is integrated with the frame 200, thereby obtaining a good visual effect. In summary, the first display unit 141 and the second display unit 142 display separately can adapt to a variety of situations.

[0061] 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.

[0062] 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 this 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.

[0063] 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.

[0064] 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 user experience.

[0065] In another embodiment, as shown in Figure 7, 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 is facing the backlight panel located in the auxiliary light-emitting area 120 to receive the light signal emitted by the backlight source assembly 130.

[0066] Because the projection of the display panel 140 on the backlight assembly 130 does not overlap with 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. In this setting, the device can adjust the backlight assembly 130 in the normal light-emitting area 110 by detecting the backlight assembly 130 in the auxiliary light-emitting area 120, thereby achieving a better display effect.

[0067] It should be noted that when the auxiliary light-emitting area 120 is provided with only the backlight assembly 130, the device measures the brightness of the backlight assembly 130 for adjustment; when the auxiliary light-emitting area 120 is provided with the backlight assembly 130 and the display panel 140, the device measures both the brightness and the grayscale of the auxiliary light-emitting area 120. Both measurement methods are embodiments of the present application and fall within the scope of protection of the present application.

[0068] In this embodiment, as shown in FIG5 , the frame 200 includes a light shielding plate 210 located on a side of the display panel 140 away from the backlight assembly 130. The minimum distance d1 between the edge of the light shielding plate 210 and 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 greater than or equal to 0.1 mm, or less than or equal to 5 mm.

[0069] The inventors discovered in actual testing that providing a certain distance between the edge of the visor 210 and the first display unit 141 allows for a certain margin during installation, facilitating subsequent installation. If no margin is provided or the margin is very small, the visor 210 may cover the first display unit 141. If the margin is too large, waste will occur and the distance from the first display unit 141 will be too large, resulting in an unsightly appearance.

[0070] Through extensive experiments, the inventors discovered that when the minimum distance d1 between the edge of the shading plate 210 and the first display unit 141 is less than or equal to 0.1 mm, installation becomes difficult and the first display unit 141 is easily obstructed. When the minimum distance d1 between the edge of the shading plate 210 and the first display unit 141 is greater than or equal to 5 mm, waste occurs and the appearance is unsightly.

[0071] Preferably, the minimum distance between the edge of the shading plate 210 and the first display unit 141 is greater than or equal to 0.5 mm and less than or equal to 2 mm. A minimum distance between the edge of the shading plate 210 and the first display unit 141 of greater than or equal to 0.5 mm and less than or equal to 2 mm is a good installation range. It not only avoids installation difficulties and obstruction of the first display unit 141, but also reduces waste and improves aesthetics.

[0072] In this embodiment, d1 is selected to be 1 mm. In other embodiments, it can also be 1.2 mm, 1.5 mm, etc.

[0073] As shown in Figure 5, the frame includes a shell 220; the shell 220 includes a fixing plate 221, and 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 fixed area 240. The sensor 300 is arranged on the fixing plate 221.

[0074] It should be noted that the fixing area 240 here is at least a partial structure of the fixing plate 221 , and the light shielding plate 210 is the fixing plate 221 , or at least a partial structure of the fixing plate 221 .

[0075] At least a portion 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 mounted on the fixing plate 221 needs to face the display module 100 within the auxiliary light-emitting area 120. Therefore, the sensor 300 is positioned between the auxiliary light-emitting area 120 and the fixing plate 221 and faces the display module 100. In other words, the sensor 300 is completely obscured by the fixing plate 221. This prevents the user from seeing the sensor 300 from the outside, achieving a concealed design that maintains the aesthetics of the device while still enabling detection functionality.

[0076] In this embodiment, the fixing plate 221 is arranged parallel to the display module 100. This ensures that the sensor 300 fixed to the fixing plate 221 faces the display module 100 to collect the optical signal from the display module 100. The sensor 300 facing the display module 100 can better receive the optical signal from the display module 100. Furthermore, the parallel arrangement of the fixing plate 221 and the display module 100 ensures a uniform and elegant appearance.

[0077] It should also be noted that an auxiliary shell 230 is further provided in this embodiment. 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 .

[0078] In another embodiment, as shown in FIG6 , 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 disposed within 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 region 240, and the sensor 300 is disposed on the fixing unit 232.

[0079] 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 .

[0080] The extension unit 231 is disposed in the housing 220 and connected to the fixing unit 232 , and supports the fixing unit 232 . In this way, 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 .

[0081] Furthermore, the fixing unit 232 is arranged parallel to the display module 100. This ensures that the sensor 300 affixed to the fixing unit 232 faces the display module 100 to collect optical signals from the display module 100. This also ensures a consistent and elegant appearance. Under normal circumstances, the user-facing portion of the housing 220 is also parallel to the display module 100, further ensuring an aesthetically pleasing appearance.

[0082] 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 sub-pixel units in at least one pixel.

[0083] 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.

[0084] In this embodiment, referring to FIG. 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°.

[0085] Through extensive experiments, the inventors discovered that when the included 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. However, when the included angle α between the sensor 300 and the auxiliary light-emitting area 120 is greater than or equal to 180°, the display module 100 becomes infinitely long. Preferably, an included angle α of 150° is selected in this application. At an included angle α of 150°, sufficient pixels are included for measurement while ensuring the length of the display module 100. In other embodiments, an angle of 120° or 140° may also be selected.

[0086] Referring to FIG. 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.

[0087] Through extensive experiments, the inventors have also discovered 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. However, 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 secures the sensor 300 becomes 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 a sufficient number of pixels for measurement while also ensuring the thickness of the frame 200.

[0088] 8 , the 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.

[0089] Furthermore, the inventors discovered 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. 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, the sensor 300 can obtain sufficient pixels for measurement while also ensuring that the length of the auxiliary light-emitting area 120 is not excessive.

[0090] 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.

[0091] When the length d3 from the 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. When the length d3 from the 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 inventors have found through extensive experiments that when the length d3 from the 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, the sensor 300 can obtain enough pixels for measurement and ensure that the length of the auxiliary light-emitting area 120 is not too long.

[0092] In addition, the current main design plan for sensor 300 is to place it in a certain space at the edge of the entire device. It can be placed at any position on the upper, lower, left, or right borders of the entire device. The middle 2 / 3 area is preferred because the closer to the corners, the worse the brightness stability and uniformity will be.
