Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic structural diagram of a display panel according to a first embodiment of the present invention. As shown in fig. 1, 2 and 3, a display panel includes: a first light-emitting region 101 and at least one mirror; wherein the first light emitting area 101 comprises at least one vector pixel 102; at least one vector pixel 102 comprises at least one vector sub-pixel emitting incident light rays of at least one angle; the at least one reflector is arranged at the first edge of the display area and used for reflecting incident light rays emitted by the vector sub-pixels through the at least one reflector and then emitting the reflected incident light rays according to a preset path to form a virtual image corresponding to the vector sub-pixels.
With continued reference to fig. 1, 2, and 3, before describing the technical solution of the embodiment of the present invention, the vector pixel 102 is described next. The vector pixel 102 is an optical device that satisfies a preset condition. The preset conditions may be: first, the vector sub-pixels narrow rays, that is, the vector pixels 102 can be viewed approximately as being made up of light sources that emit light one by one, relative to a larger display area; at least one light ray emitted into space by the vector pixel 102 has the following characteristics: the light rays emitted by the vector pixels can be understood as a cone with the light source as the center, see fig. 2; if the light boundary is defined by the light intensity falling to fifty percent of the light, the minimum spatial spherical angle which can include all the boundaries is less than 10 degrees by taking the light source as the center of a circle; second, the vector pixels 102 may be projected into at least 100 distinguishable directions; third, the vector pixel 102 may emit light in two or more directions simultaneously, that is, there may be two or more sub-pixels in the vector pixel 102 operating simultaneously; fourth, the light intensity of the vector pixels 102 can be adjusted, i.e., the intensity of the light emitted by each vector sub-pixel in a vector pixel 102 can be adjusted.
It can be understood that the vector pixels 102 are composed of a dense display device and an optical module, a basic light emitting unit of the dense display device is called a vector sub-pixel, and light emitted by each vector sub-pixel can be modulated by the optical module of the vector pixel to form light pointing to a specific direction in space, as shown in fig. 3. Since the ray angles of the vector sub-pixels are typically small, after the pupil location of the user is determined using an eye tracking module disposed in the display system, the one or more vector sub-pixels that are illuminated may be determined. In short, the vector pixels 102 are formed by at least one vector sub-pixel, and each vector sub-pixel emits light with a certain directivity.
The interface for video playing or image displaying in the display device may be referred to as a display interface, that is, the first light-emitting area 101 in this embodiment. The size and shape of the first light-emitting area 101 can be set by a user according to actual needs. Alternatively, the first light-emitting region 101 may be an arc-shaped, planar, or curved surface. The screen displayed by the first light emission area 101 can be realized by the vector pixels 102 laid out in the first light emission area 101. Having briefly introduced vector pixels 102 above, it can be determined that vector pixels 102 are composed of at least one vector sub-pixel, i.e., at least one vector sub-pixel, each of which can emit light to a different angle, and an eye tracking module can be disposed in the display device, which can determine which vector sub-pixel in the vector pixel emits light according to the pupil position of the user.
In order to enlarge the display area of the display interface, at least one mirror may be disposed at a preset position of the first light emitting area 101. A mirror is an optical component that works using the law of reflection. The reflecting mirror can be divided into a plane reflecting mirror, a spherical reflecting mirror and an aspheric reflecting mirror according to the shape; according to the degree of reflection, the reflection type liquid crystal display device can be divided into a total reflection mirror and a semi-transmission and semi-reflection mirror (also called a beam splitter). In this embodiment, a plane, total reflection mirror may be used. The number of the at least one mirror may be one, two, or more, and the user may set the number of the mirrors according to the display area to be enlarged.
The arrangement of the reflector in the display panel may be: the length of at least one edge of the first light-emitting area can be equal to that of the edge of the display panel, the width is minimum, and the reflector can receive light beams emitted by the vector pixels arranged at the edge of the first light-emitting area.
In order to more clearly describe the technical solution of the embodiment of the present invention, a principle that each vector sub-pixel in the vector pixel is imaged by reflecting with a plane mirror, that is, a principle that the vector pixel in the first light emitting area operates, is described first. When a user looks directly at the display screen, the vector pixels laid out on the display interface can be illuminated and seen by the user. Referring to fig. 4, for example, the light emitted from the vector sub-pixel 1021 in the illuminated vector pixel 102 may directly enter the user's eye, i.e. the user may observe that the vector sub-pixel 1021 in the vector pixel 102 is illuminated. Correspondingly, the vector sub-pixel 1022 in the appropriate vector pixel 102 is selected to be lit, that is, after the pupil position of the user is determined by the human eye tracking device, the appropriate vector sub-pixel 1022 may be determined by the corresponding processing device, and the light of the vector sub-pixel 1022 enters the eye of the user after being reflected by the plane mirror 1024 and changing the propagation direction, so that the user may see that the vector sub-pixel 1022 in the vector pixel 102 is lit. The light emitted by the vector sub-pixel 1023 is not visible to the user. Since the vector sub-pixel bright-dark state in vector pixel 102 can be controlled individually, vector sub-pixel 102 and the virtual image corresponding to the vector pixel sub-pixel can be considered as two separate pixels. Since the ray angle of the vector sub-pixels is small, the size of the plane mirror is limited, and the distance of the observer from the first light-emitting area 101 is limited, a certain sub-pixel among the vector pixels that can be determined according to the human eye tracking device can be seen by the user. If the emergent light emitted by a certain sub-pixel in the calculated vector pixels is reflected by the mirror surface, the reflected light can be emitted into the eyes of the user, the light directly emitted by the vector sub-pixel necessarily points to the mirror surface instead of the direction of the user, so that the real display screen seen by the user and the virtual image display screen imaged by the mirror surface are mutually independent, the display pixels of the real display screen and the virtual image display screen cannot influence each other, and the technical effect of expanding the display area is achieved.
On the basis of the technical scheme, the reflector can be applied to the vector pixel display screen to achieve the technical effect of enlarging the display area.
To describe the technical solution of the embodiment of the present invention in more detail, the first light emitting area 101 is taken as a curved surface as an example to describe the solution, and with reference to fig. 1 to 4, a vector pixel 102 is disposed on a curved surface screen, two reflecting mirrors are respectively disposed at curved edges of the curved light emitting area, and accordingly, the first edge can be understood as a curved edge of the curved light emitting area. Human eye tracking module in the display system can acquire user's pupil position, and with user's pupil for to sending processing apparatus in the display system, processing apparatus can be according to user's pupil position determination vector pixel display screen on treat luminous vector sub pixel, some vector sub pixel can form the virtual image corresponding with some vector sub pixel through the plane mirror reflection back that the top edge set up, obtain first virtual image face 1011, it is corresponding, some point vector sub pixel can form the virtual image corresponding with vector sub pixel through the plane mirror reflection back that the bottom edge set up in addition, obtain second virtual image face 1012, the display area who obtains this moment can be the triple of display screen area.
It should be noted that even if the same sub-image is displayed, the vector sub-pixels that may be lit may be the same or different when the user is located at different positions. Specifically, which of the vector subpixels is to be lit is mainly calculated by a processing device provided in the display device based on the pupil position acquired by the person tracking module and the parameter information of the display device, and it is determined which of the vector subpixels is to be lit.
Referring to fig. 5, if the first light emitting area 101 is a flat type, the reflecting mirrors 103 may be disposed on both left and right sides of the flat type display panel. Because the positions of the users are different, the human eye tracking module arranged in the display device can determine the positions of the pupils of the users, and determine that the vector sub-pixels corresponding to the positions of the pupils of the users are lightened according to the positions of the pupils of the users. That is to say, according to the position where the user is located, the appropriate sub-pixels are selected to be lit so that the light reflected by the plane mirror 103 can enter the pupil of the user, and the user can see the virtual image formed by the vector pixels passing through the plane mirror while watching the vector pixel display screen, so that the effect of expanding the visual field can be achieved, namely the display area at the moment is three times that of the display screen.
The display device on which the display panel provided in this embodiment is mounted further includes an eye tracking module and a processing device. The human eye tracking module is used for acquiring the pupil position of a user, and the processing device determines the target vector sub-pixel to be emitted in the first light emitting area according to the pupil position of the user.
The principle that the at least one reflector is arranged at the edge of the first light-emitting area to enlarge the display area is as follows: when the vector sub-pixels emit the emission light and an included angle exists between the emission light and the reflector, the emission light can enter the pupil of the user after being reflected by the reflector, and a virtual image corresponding to the vector sub-pixels of the emission light is formed in the reflector surface, so that the display area is enlarged.
On the basis of the above technical solution, it should be further noted that, because there may be a loss of light energy in the light reflected by the mirror and entering the pupil of the user, it is necessary to perform brightness compensation on the vector sub-pixels viewed by the user after being reflected by the mirror. At this time, the eye tracking module disposed in the display device may determine the vector sub-pixels for compensating the optical energy loss according to the located pupil position information, and then perform brightness compensation on the luminous vector sub-pixels according to the content displayed on the display screen.
According to the technical scheme of the embodiment of the invention, at least one reflector is arranged at the edge of the first light-emitting area and is used for reflecting incident light rays emitted by the vector sub-pixels through the at least one reflector and then emitting the reflected incident light rays according to a preset path to form a virtual image corresponding to the vector sub-pixels, so that the technical problems of high cost and resource waste caused by the fact that more vector pixels need to be arranged on a display interface when a large screen is displayed in the prior art are solved, the area of the display interface is increased, the production cost is reduced, and the technical effect of user experience is improved.
Example two
On the basis of the above technical solution, in order to enlarge the display area, at least two light emitting areas may be spliced, and in this embodiment, the two light emitting areas are spliced as an example.
Fig. 6 is a schematic view of a display panel structure according to a second embodiment of the present invention. Referring to fig. 6 and fig. 3 or 4, the interface panel further includes: the second light emitting area 201 and the at least one reflecting mirror 103 are disposed at the first light emitting area 101 and the second edge of the second light emitting area 201, and are used for reflecting incident light rays emitted by the at least one vector sub-pixel to the pupil of the user. In the present embodiment, the first light-emitting region and the second light-emitting region mentioned in the present embodiment are regions where vector pixels are mounted, and in the present embodiment, the light-emitting region of the display panel is divided only for different installation modes of the plane mirror.
In order to enlarge the area of the vector pixel display screen, at least two vector pixel display screens, that is, two light-emitting areas, may be combined, in addition to the technical solution mentioned in the first embodiment.
The combination mode can be that two vector pixel display screens, or a plurality of vector pixel display screens are packaged on the same horizontal plane, or can be packaged on different horizontal planes. In the process of practical application, it is only an ideal state to package two vector pixel display screens on the same plane, and most of the two or more plane vector pixel display screens are packaged on multiple planes. Optionally, two vector pixel display screens are encapsulated on two planes. That is, when the first light-emitting region 101 and the second light-emitting region 201 are joined, they are packaged on different planes. With continued reference to fig. 7, optionally, the second light-emitting area 201 is disposed on a second plane, and the first light-emitting area 101 is disposed on a first plane, the first plane and the second plane being parallel to each other. The first plane and the second plane have a certain height difference, and the vertical height of the first plane is higher than that of the second plane, or the vertical height of the second plane is higher than that of the first plane. In this embodiment, the vertical height of the second plane may be higher than that of the first plane, and it may be further understood that, based on the viewing position of the user, the first horizontal plane is close to the viewing side, and the second horizontal plane is far from the viewing side. In the splicing process, as long as the first light-emitting region and the second light-emitting region are not on the same horizontal plane, no matter how the first light-emitting region 101 and the second light-emitting region 201 are arranged, the first light-emitting region 101 and the second light-emitting region 201 have a gap.
When a user views a display interface, a gap between the vector pixel second light emitting area 201 and the first light emitting area 101 may be seen due to a large angle between the user and a normal direction of the vector pixel display screen, so that the display interface is incomplete, and the problem of poor user experience may occur. Illustratively, referring to fig. 7, the arrangement between the first light-emitting area 101 and the second light-emitting area 201 is as shown in the figure, when the user looks at a viewpoint a, the user can see a perfect display screen, and when the user looks at B viewpoint, the user may see a gap between the second light-emitting area 201 and the first light-emitting area 101, and the display effect is poor. On the basis of the above technical solution, at least one reflecting mirror 103 may be arranged at the gap between the second light emitting area 201 and the first light emitting area 101, and with continued reference to fig. 6, that is, a flat mirror 103 may be arranged vertically at the gap between the first horizontal plane and the second plane. When the human eye tracking module in the display system detects the pupil position of the user, the processing device in the display system may determine which vector sub-pixel in the second light-emitting region 201 can enter the pupil of the user after being acted by the mirror 103 according to the pupil position of the user, so as to avoid seeing a gap between the second light-emitting region 201 and the first light-emitting region 101. That is, the light emitted by the vector sub-pixels on the second light emitting area 201 exits to the reflector 103, can enter the pupil of the user after being acted by the reflector 103, and due to the reversibility of the light, a virtual image corresponding to the light emitting vector sub-pixels can be formed, so that the gap between the second light emitting area 201 and the first light emitting area 101 is effectively shielded, and a perfect display screen can be seen no matter where the user is.
The embodiment of the invention also provides a display system, which comprises a human eye tracking device, a processing device and the display panel provided by the embodiment of the invention, and when the display panel provided by the embodiment of the invention is adopted, the technical effects of enlarging the display area of a display surface, realizing 3D display of a square naked eye and improving the user experience can be realized.
According to the technical scheme of the embodiment of the invention, the at least one reflector is arranged at the gap of the at least two light-emitting areas and used for reflecting the incident light emitted by the at least one vector sub-pixel to the pupil of the user, so that the technical problem that the effect of the viewed display interface is poor if the position of the user is compared and calculated when the at least two light-emitting areas are spliced for enlarging the display surface in the prior art is solved, the display area is enlarged through the reflector arranged at the gap, the integrity of the display interface is achieved, and the technical effect of user experience is improved.

The number of the at least one reflecting mirror can be one, two or more, and the user can determine according to actual requirements. The position at which the at least one mirror is arranged, and the dimensions of the mirror, are predetermined. The vector pixels include a plurality of vector sub-pixels. It is therefore necessary to determine the vector sub-pixels of the vector pixels that need to emit light. The luminous vector sub-pixels are determined according to the pupil position coordinates of the user. And taking the luminous vector sub-pixel as a target vector sub-pixel. And respectively determining the coordinates in the target vector sub-pixels by the driving software in the display device, and taking the coordinates determined at the moment as the target vector sub-pixel coordinates.
Specifically, according to the coordinates of the pupil, the size of at least one reflector and the set position, the light beams emitted by vector sub-pixels in each vector pixel can be calculated and obtained, and the light beams can directly reach the pupil of the user through the display screen. Of course, it can also be calculated which vector sub-pixels emit light beams which can enter the pupil of the user after being acted by the reflector.
Optionally, before determining the target vector sub-pixels, the method further includes: determining at least one vector sub-pixel on the display panel and virtual image coordinates formed by at least one reflector; wherein, the vector pixel comprises at least two vector sub-pixels.

According to the vector pixel coordinates and the virtual image corresponding to the vector pixel, it can be determined which vector sub-pixels can emit light rays which can directly reach the pupil of the user. According to the calculation method, which vector sub-pixel on the display panel can enter the pupil of the user after being reflected by the mirror surface can be determined, so that the target vector sub-pixel is obtained.

Note that, the image formed by the light emitted from the vector sub-pixel obtained at this time is referred to as a virtual image.
In the present embodiment, the vector pixel includes a plurality of vector sub-pixels, each of which can emit a light beam in a predetermined direction. When the light beams emitted by the vector sub-pixels can directly enter the pupils of the user, the image seen by the user at the moment is called a real image; and the light beams emitted by part of the vector sub-pixels need to be emitted by a mirror surface and then enter the pupils of the user, and the image seen by the user in the condition is called a virtual image.
Specifically, a vector sub-pixel entering the pupil of the user through the display screen is used as a first vector sub-pixel, and an image formed by the first vector sub-pixel is a real image; taking a vector sub-pixel which enters the pupil of the user after the action of at least one reflector as a second vector sub-pixel, wherein an image formed by the second vector sub-pixel is a virtual image; respectively determining the coordinates of the first vector sub-pixel and the coordinates of the second vector sub-pixel; and taking the coordinates of the first vector sub-pixel and the coordinates of the second vector sub-pixel as target vector sub-pixel coordinates.
