[0006] For a single display screen above 50 inches, facing the viewer through the mechanical structure can only be to direct the center point of the display screen to the viewer, while the display screen is a large plane or curved area, and at the same time display With multiple signal source windows, when the viewer watches at a certain position, it cannot be satisfied that all signal source windows are viewed at normal angles
[0007] For arrays of more than four 20"+ displays, it is possible to mechanically orient each display individually to the viewer, but this would result in a larger display in the OR The movement of the array, on the one hand, may cause overlap and occlusion between the display screens. On the other hand, for operating rooms with more medical equipment, multiple display screens simultaneously produce independent mechanical movements that may cause collision damage between equipment. Probability rises
The above two points will lead to occlusion or interruption of the signal source picture, which may be fatal in major operations such as heart surgery and craniotomy
In addition, in the operating room scene, the electric screen angle mechanical adjustment method will inevitably use devices such as motors that generate strong electromagnetic interference. This electromagnetic interference is very serious for medical equipment in the operating room. In extreme cases It may even lead to surgical accidents

Embodiment 1
[0074] Example 1: Combination Figure 2 to Figure 3 Describe the single-screen display method of the present invention;
[0075] like figure 2 The illustrated embodiment of the positioning device 01 using an infrared sensor for positioning includes the following working steps:
[0076] The control device 02 locates the viewer 08 through the positioning device 01, and obtains the position information of the relative position of the viewer 08 and the display device 04;
[0077] Analyze the location information according to the signal source priority order and layout arrangement, and obtain the corresponding multi-signal source splicing layout information;
[0078] The video signal splicing device 03 performs splicing processing on the input signal source according to the multi-signal source splicing layout information, and outputs the splicing-processed signal source;
[0079] The spliced-processed signal source is displayed and outputted through the external device of the d...
Embodiment 2
[0118] Example 2: as Figure 4 In the illustrated embodiment, the display device 04 is composed of a display screen 0411, a display screen 0412, a display screen 0413, a display screen 0414, a display screen 0415, and a display screen 0416, and the six display screens are distributed on a cylindrical surface;
[0119] like Figure 4 As shown, the positioning device 01 is a camera 0111 ; the camera 0111 is located at the center of the display screen array of the display device 04 .
[0120] The user specifies a priority higher than other signal sources based on the interaction with the control device 02;
[0121] combine Figure 4 to Figure 5 Describe how the positioning device 01 obtains the relative position information of the viewer 08 and the display device 04 through the camera 0111, thereby enabling the display system to perform multi-screen display, including:
[0122] The control device 02 locates the viewer 08 through the positioning device 01, and obtains the posit...

Abstract
The invention discloses a display device and a display method thereof, and the display device comprises a positioning device, a control device, a video signal splicing device and a display device. The display method comprises the steps that a control device positions a viewer through a positioning device, and position information of relative positions of the viewer and the display device is obtained; analyzing the position information according to the priority sequence and the layout arrangement mode of the signal sources to obtain corresponding multi-signal-source splicing layout information; the video signal splicing device performs splicing processing on the input signal source according to the multi-signal-source splicing layout information, and outputs the spliced signal source; and the spliced signal source displays and outputs a display picture through external equipment of the display device. According to the invention, the layout condition of each signal source of the spliced picture on the display device can be adjusted according to the position of the viewer, and the picture with the priority higher than that of other main signal sources is displayed at the window position of the best viewing angle of the viewer, thereby ensuring that the main signal source obtains the best display effect.
Description
technical field [0001] The invention belongs to the technical field of display devices, and in particular relates to a display device and a display method thereof. Background technique [0002] With the development of information technology, the operating room of the hospital is equipped with a variety of medical electronic equipment, such as ECG monitors, digital subtraction angiography (DSA), endoscopes, imaging systems, ultrasonic diagnostic instruments, etc. The equipment has video signals that need to be displayed during the operation. In order to facilitate the doctor's reference and comparison of various video signals, the current common practice is to use a video splicing device to splicing multiple video signal sources according to the layout required by the user. One or more monitors are used to display the picture, so that a variety of video signals can be displayed simultaneously. In this display mode, the display area of each signal source is called a window,...
