[0026] Humanistic care for patients in medical scenarios includes: pushing detailed surgical information to patients before surgery to promote doctor-patient communication; distracting patients during surgery to relieve pain and reduce drug use. It can soothe patients before and during surgery, improve surgical comfort, shorten patient recovery time, and promote rehabilitation.

[0027] As one of the display technologies, AMOLED near-eye display technology has the advantages of flexibility, high color saturation and contrast, fast response time and low power consumption, showing great potential in medical and humanistic care.

[0028] In the related technologies, the display terminal is used in medical scenarios mainly including:

[0029] The first category is the VR head-mounted display solution. The advantage of this solution is that it has an excellent sense of immersion, is not easily disturbed, and provides richer content. However, some people will feel 3D dizzy, causing discomfort, and obvious pressure on the eyes and head. In addition, the cost of the whole machine is high, and the production requirements for demonstration content are higher. Especially in preoperative and intraoperative scenes, doctors cannot fully see the patient's condition, and complete immersion affects the interaction between doctors and patients. At the same time, in the head-mounted display solution, the display terminal cannot be adaptively adjusted for different groups of people, such as children and adults, and has a narrow scope of application.

[0030] The second category is the direction of replacing consumer electronic products. The advantage of this solution is that it is the simplest and most universal. The main problem is that electronic products have safety hazards such as falling and harming patients in medical environments such as operating rooms. During surgery or emergencies, the communication function of electronic products may lead to safety hazards such as leakage of patient privacy.

[0031] The above problems affect user experience satisfaction. In order to overcome at least one of the above problems, the present application provides a display terminal and a display device, which determine the curvature of the areas on both sides of the display screen by analyzing the comfortable viewing angle and viewing distance of the human eye in the near-eye display scene, so as to better adapt to the near-eye display scene and improve user experience satisfaction.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] In the accompanying drawings, the sizes of layers and regions may be exaggerated for clarity of illustration. It is understood that when a structure is referred to as being "on or under" another structure, the structure may be directly on or under the other structure, or there may be intermediate structures. The same reference numerals always indicate the same structure. The structures mentioned herein include any of a film layer, an element, a device, a component, and an assembly.

[0034] When a structure is referred to as being “connected” to another structure, the structure may be directly connected to the other structure or indirectly connected to the other structure with one or more intervening structures interposed therebetween.

[0035] Figure 1 A schematic diagram of a top view of the structure of a display terminal provided in one embodiment of the present application. Figure 2 for Figure 1 The figure shows a schematic diagram of the cross-sectional structure of the display terminal along line N1N2. Figure 3 for Figure 2The display terminal provided in the embodiment of the present application can be installed on a multi-degree-of-freedom bracket, and the multi-degree-of-freedom bracket can be installed on a hospital bed, a recliner, or a massage chair to achieve near-eye display.

[0036] Combination Figure 1 , Figure 2 and Figure 3 As shown, the display terminal includes a display module 10 and a support structure 20. The support structure 20 is fixed on the non-display side of the display module 10. The support structure 20 includes a first fixed support portion 21, a connecting portion 22, and a second fixed support portion 23 connected in sequence. The first fixed support portion 21, the connecting portion 22, and the second fixed support portion 23 are respectively fixedly connected to the display module 10. The fixed connection mentioned here refers to a fixed connection, for example, the first fixed support portion 21 is bonded and fixed to the display module 10, and the second fixed support portion 23 is bonded and fixed to the display module 10. The bending radius of any one of the first fixed support portion 21 and the second fixed support portion 23 is greater than or equal to 300 mm and less than or equal to 350 mm.

[0037] In one embodiment, the central angle of any one of the first bending support portion 21 and the second bending support portion 23 in the first direction x is greater than or equal to 30° and less than or equal to 40°. The bending radius is perpendicular to the first direction x. The central angle in the first direction x limits the length of the display terminal in the first direction x. Exemplarily, the first direction x is a horizontal display direction.

[0038] The display module 10 has a display function. Exemplarily, the display module 10 includes a flexible display module. When the display module 10 is not assembled with the support structure 20, the display module 10 can be in a flat state. Figure 2 As shown, after the display module 10 is assembled with the support structure 20, the first area of ​​the display module 10 adapts to the curvature of the first bending support portion 21 to form a first curved area, and the second area of ​​the display module 10 adapts to the curvature of the second bending support portion 23 to form a second curved area. Exemplarily, the first bending support portion 21, the connecting portion 22 and the second bending support portion 23 can be a rigid shell structure.

[0039] The inventors have found that during near-eye display, in the horizontal display direction, for example, in the first direction x, the comfortable viewing angle range of the human eye is approximately between 60° and 90°, and the optimal near-eye display distance is approximately between 300mm and 350mm. Based on this, in the embodiment of the present application, the bending radius R of any one of the first fixed bending support portion 21 and the second fixed bending support portion 23 is set to be greater than or equal to 300mm and less than or equal to 350mm, and the central angle α is taken as half of the comfortable viewing angle range of the human eye, that is, greater than or equal to 30° and less than or equal to 40°. In this way, the display terminal provided in this embodiment is used for near-eye display, such as in medical scenarios, which can ensure that the human eye is more comfortable and improve user experience satisfaction.

[0040] Exemplarily, the bending radius R of any one of the first bending support portion 21 and the second bending support portion 23 is 300 mm, 320 mm, 340 mm, 350 mm, etc. The central angle α of any one of the first bending support portion 21 and the second bending support portion 23 is 30°, 33°, 36°, 39°, 40°, etc.

[0041] Figure 4 for Figure 1 The cross-sectional structure diagram of the display terminal along the N3N4 line is shown. Figure 1 , Figure 2 and Figure 4 As shown, the included angle β formed by the end point Q of the generatrix L1 of any one of the first bending-fixing support portion 21 and the second bending-fixing support portion 23 and the virtual connecting line L2 of the center O and the bending radius R is greater than or equal to 15° and less than or equal to 20°, the generatrix L1 is parallel to the second direction y, and the second direction y is perpendicular to the first direction x. Exemplarily, the included angle β is 15°, 17°, 19°, 20°, etc.

[0042] The track of the continuous movement of the generatrix L1 (straight line or curve) in space forms a curved surface, namely the first bending-fixing support portion 21 and the second bending-fixing support portion 23. The center O refers to the end point of the bending radius R away from the display module 10.

[0043] The inventors further discovered that, during near-eye display, in the vertical display direction, for example, in the second direction y, the comfortable viewing angle range of the human eye is between 30° and 40°. Therefore, according to the display terminal provided in this embodiment, by setting the angle β to be generally the comfortable viewing angle range of the human eye in the vertical direction, that is, the angle β is greater than or equal to 15° and less than or equal to 20°, the comfort of near-eye display can be further improved, thereby improving user experience satisfaction.

[0044] In one embodiment, Figure 4 As shown, the generatrix L1 of any one of the first bend fixing support portion 21 and the second bend fixing support portion 23 is a straight line. In this way, the first bend fixing support portion 21 and the second bend fixing support portion 23 are easy to prepare.

[0045] In one embodiment, Figure 1 As shown, the dimension C of the display module 10 is greater than or equal to 16 inches and less than or equal to 18 inches. In one embodiment, the aspect ratio of the display module 10 is greater than or equal to 20:9 and less than or equal to 22:9. For example, the aspect ratio of the display module 10 is 20:9, 21:9, or 22:9.

[0046] Figure 5 Another embodiment provides Figure 1 The cross-sectional structure diagram of the display terminal along the N1N2 line is shown in FIG. Figure 5 As shown, in this embodiment, the connection portion 22 includes a plurality of support sub-portions 221. In the direction from the first bending support portion 21 to the second bending support portion 23, adjacent support sub-portions 221 are rotationally connected.

[0047] In this case, the posture of the support sub-section 221 can be changed by adjusting the rotation angle between the multiple support sub-sections 221. For example, the multiple support sub-sections 221 include a first support sub-section and a second support sub-section, and the first support sub-section and the second support sub-section are respectively located at the two ends of the multiple support sub-sections 221. The first support sub-section is adjusted so that the first support sub-section and the first fixed bending support section 21 are co-curved; the second support sub-section is adjusted so that the second support sub-section and the second fixed bending support section 23 are co-curved; and the support sub-sections 221 other than the first support sub-section and the second support sub-section are adjusted to be co-planar. In this way, the larger the interpupillary distance of the user, the more the number of support sub-sections 221 co-curved with the first fixed bending support section 21 and the more the number of support sub-sections 221 co-curved with the second fixed bending support section 23 can be increased; the smaller the interpupillary distance of the user, the less the number of support sub-sections 221 co-curved with the first fixed bending support section 21 and the more the number of support sub-sections 221 co-curved with the second fixed bending support section 23 can be reduced. It can be seen that the display terminal provided in this embodiment can be adaptively adjusted according to the size of the pupil distance of the user.

[0048] In one embodiment, the connection portion 22 includes a plurality of supporting sub-portions 221, and the plurality of supporting sub-portions 221 are sequentially rotated and connected in a direction from the first bending support portion 21 to the second bending support portion 23. When the plurality of supporting sub-portions 221 are in a coplanar state, the plurality of supporting sub-portions 221 are arranged along a first direction x, and in the first direction x, a width D of the connection portion 22 is greater than or equal to 50 mm and less than or equal to 70 mm.

[0049] The inventor has found that, generally, the through-hole spacing of adult males is between 60 mm and 70 mm, the through-hole spacing of adult females is between 56 mm and 64 mm, and the through-hole spacing of children is about 55 mm. Based on this, the embodiment of the present application sets the width D of the connecting portion 22 to be greater than or equal to 50 mm and less than or equal to 70 mm, which can better adapt to all user groups.

[0050] It should be noted that the rotational connection structure between adjacent supporting sub-parts 221 can be implemented by using structures in related technologies, such as a rotating shaft, which can also have a multi-angle limit function to maintain the posture of the supporting sub-parts 221. The embodiment of the present application does not limit the rotational connection structure between adjacent supporting sub-parts 221.

[0051] Figure 6 for Figure 5 The structural diagram of the display module in the display terminal is shown. Figure 6 The display module 10 is shown in the state when it is not assembled with the support structure 20. Figure 5 and Figure 6 As shown, the display module 10 includes a flexible panel 11 and a plurality of support plates 12, and the support plates 12 are fixed between the flexible panel 11 and the support structure 20. The plurality of support plates 12 include a plurality of support bars 121, and the support bars 121 are fixed correspondingly to the support sub-portions 221. Exemplarily, the support plate 12 includes a steel sheet. In this way, it is possible to avoid the support sub-portion 221 being directly fixed to the flexible panel 11 to cause pulling, thereby improving the reliability of the display module.

[0052] Figure 7 for Figure 6 The following is a partial enlarged view of the display module. Figure 6 and Figure 7 As shown, the plurality of support bars 121 include a central support bar 1211 and a plurality of edge support bars 1212, and the plurality of edge support bars 1212 are evenly arranged on both sides of the central support bar 1211. In the arrangement direction of the plurality of support sub-portions 221, the width D1 of the central support bar 1211 is greater than the width D2 of the edge support bar 1212. Exemplarily, the width D1 of the central support bar 1211 is about 55 mm to adapt to the pupil distance of children.

[0053] In one embodiment, in combination Figure 5 and Figure 6 As shown, the plurality of support plates 12 further include a first support plate 122 and a second support plate 123 . The first support plate 122 is fixedly connected to the first bending fixing support portion 21 , and the second support plate 123 is fixedly connected to the second bending fixing support portion 23 .

[0054] In one embodiment, in combination Figure 5 , Figure 6 and Figure 7As shown, the thickness of the first support plate 122 and / or the second support plate 123 is less than the thickness of the support bar 121. Since the area of ​​the support bar 121 is smaller than the first support plate 122 and the second support plate 123, if the thickness of the support bar 121 is set to be less than or equal to the thickness of the first support plate 122 and the second support plate 123, the reliability and support strength of the support bar 121 are difficult to meet the requirements. Therefore, in this embodiment, by setting the thickness of the support bar 121 to be greater than the thickness of the first support plate 122 and the second support plate 123, it can be ensured that the reliability and support strength of the support bar 121 meet the requirements.
