Referring to fig. 1, fig. 1 is a schematic view of a display device 100 according to an embodiment of the invention.
A display panel may include a main display region 11 and a transparent region 12 at least partially surrounded by the main display region 11. One side surface of the transparent region 12 is provided with the fast moving type display device 4. When the fast moving display device 4 moves fast to the transparent area 12, the fast moving picture of the fast moving display device 4 and the display picture of the main display area 11 are spliced into an integral picture. When the fast-moving display device 4 moves out of the transparent region 12, incident light incident from the other side surface of the transparent region 12 is transmitted through the transparent region 12.
In the display panel of an embodiment, the display panel further includes a micro-optical element 3. The micro-optical element 3 may be disposed between the transparent region 12 and the fast moving display device 4 for adjusting a display position of a fast moving picture of the fast moving display device 4. And/or, the micro-optical element 3 may be disposed outside one side surface of the transparent region 13 for adjusting incident light incident from the other side surface of the transparent region 12. That is, the micro-optical element 3 may be used to adjust the picture displayed by the fast moving display device 4 to a position matching the picture displayed by the main display area 11, and may also be used to adjust the incident light entering the transparent area 12; the micro-optical element 3 may have any one of the above functions alone or both of the above functions.
The display panel provided by the invention can be applied to a display device. The display device of an embodiment of the invention can comprise a display panel, a camera module and a fast moving display device. The display panel includes a main display region and a transparent region adjacent to each other. The camera module is arranged on one side of the transparent area. The fast moving type display equipment is arranged between the transparent area and the camera module. When the display panel is used for displaying a picture in a full screen mode, the fast moving type display equipment moves to the transparent area and synchronously displays the picture corresponding to the transparent area, and the picture displayed by the fast moving type display equipment and the picture displayed by the main display area are spliced into an integral picture. When the camera module is in the leading mode of shooing, the portable display device of high speed shifts out the transparent area and stops in the position that does not shelter from the camera module, and the camera module sees through the transparent area and shoots the image.
In different embodiments, the display device further includes a micro optical element disposed at one side of the transparent region and corresponding to the camera module.
Referring to fig. 1, the display device 100 of the present invention may include a display screen 1, a camera module 2, a micro-optical element 3, and a fast moving display device 4. The display screen 1 includes, but is not limited to, OLED (organic light emitting diode), micro LED (micro light emitting diode), LCD (liquid crystal display) and other types of display screens.
The display screen 1 has a main display area 11 and a transparent area 12 adjacent to each other. The transparent region 12 may be rectangular, circular, elliptical, or the like in outline. The area of the main display area 11 is generally far larger than that of the transparent area 12, the transparent area 12 has the effect that when the camera module 2 is in the front shooting mode, the transparent area 12 is in a transparent state, light ray shooting of the camera module 2 is not affected, and when the display screen 1 displays on a full screen, the transparent area 12 and the main display area 11 are matched to present a complete display picture.
The camera module 2 is disposed on the non-display side of the display screen 1 and corresponds to the transparent area 12. The camera module 2 can be used to shoot a scene towards the display side of the display screen 1, for example, a front camera in a mobile phone.
The micro-optical element 3 is disposed in the transparent region 12 and corresponds to the camera module 2. The micro-optical element 3 may act as an optical lens, either integrated directly on the transparent area 12 of the display screen 1 or as a separate element arranged between the display screen 1 and the fast-moving display device 4.
The fast moving display device 4 is disposed between the micro optical element 3 and the camera module 2. The fast moving display device 4 is used to provide a narrow strip or block display screen, and can change the display screen in real time through program control. The fast moving display device 4 is located between the micro optical element 3 and the camera module 2 in the vertical direction of the display plane of the display screen 1, and the fast moving display device 4 is movable in the parallel direction of the display plane of the display screen 1, including but not limited to linear motion and rotational motion.
When the display screen 1 is used for displaying a picture in a full screen mode, the fast moving display device 4 moves to the transparent area 12 and synchronously displays a picture corresponding to the transparent area 12, and the picture displayed by the fast moving display device 4 is located on the same plane with the picture displayed by the main display area 11 after passing through the micro optical element 3. The full screen display refers to displaying the picture by using the main display area 11 and the transparent area 12 of the display screen 1 at the same time. The micro-optical element 3 can image the picture displayed by the fast moving display device 4 and then the picture is positioned on the same plane with the display picture on the main display area 11, so that the optimized full-screen display effect can be realized.
When the camera module 2 is in the front shooting mode, the fast moving display device 4 moves out of the transparent area 12 and stops at a position where the camera module 2 is not shielded, and the camera module 2 shoots an image through the micro optical element 3. When the camera module 2 photographs a picture, the fast moving display device 4 may be parked at the edge of the transparent region 12 or at an outer region. The camera module 2 shoots images towards the display side of the display screen 1 through the micro optical element 3, so that the shooting angle of the camera can be increased.
As shown in fig. 2 to 4, fig. 2 to 4 are schematic diagrams of the working principle of the display device according to different embodiments of the present invention. In such embodiments, the fast moving display device comprises light-emitting pixel stripes 41 having a display area smaller than transparent regions 12. Optionally, the fast moving display device 4 comprises stripes of OLED or micro led light emitting pixels. In practical application, the display parameters such as the brightness, the chromaticity or the pixel density of the OLED light-emitting pixel strip or the micro led light-emitting pixel strip are as consistent as possible with the corresponding display parameters of the display screen 1 in the main display area 11, so as to further improve the display effect of the full-screen.
When the display screen 1 is used for displaying a picture on a full screen, the light-emitting pixel bars 41 sweep across the transparent area 12 within the persistence time interval and synchronously display a partial picture corresponding to the transparent area 12, and the partial picture displayed by the light-emitting pixel bars 41 is on the same plane as the picture displayed by the main display area 11 after passing through the micro-optical element 3. Based on the principle of persistence of vision of the human eye, a light-emitting pixel bar 41 rapidly scanned across a transparent region 12 may present a display corresponding to the entire transparent region, for example, for a period of 0.1 to 0.4 seconds. When the camera module 2 is in the front shooting mode, the light-emitting pixel strip 41 stops moving and stops at a position not blocking the camera module 2, and the camera module 2 shoots an image through the micro optical element 3.
As shown in fig. 2, the fast moving display device 4 may comprise a rotating strip of light emitting pixels 41. When the display screen 1 is used for displaying a picture on a full screen, the fan-shaped area swept by the rotating light-emitting pixel bars completely covers the transparent area 12, the rotating light-emitting pixel bars sweep the transparent area 12 within the persistence of vision time interval and synchronously display the partial pictures corresponding to the transparent area 12. Fig. 2 shows the rotating light-emitting pixel strip as rotating clockwise, but the rotating light-emitting pixel strip may also be rotating counterclockwise; fig. 2 shows that the rotating light-emitting pixel strip may be rotated through the transparent area 12 in a complete revolution, but the rotating light-emitting pixel strip may also be rotated back and forth through the transparent area only. The rotation type light-emitting pixel strips can be driven by the micro motor to rotate like a fan or a pendulum, and optionally, the rotation type light-emitting pixel strips keep rotating at a constant speed. The rotation axis is disposed at a position not to block the camera module 2, such as at the edge of the transparent region 12 or at the outer region. In order to sweep the whole transparent area to realize picture display, the rotary luminous pixel bar needs to be matched with the size of the transparent area, and the pixels required to be lightened on the edge are not fixed.
As shown in fig. 3 and 4, the fast moving display device 4 may comprise a translating strip of light emitting pixels 41. When the display screen 1 is used for displaying a picture in full screen, the rectangular area swept by the translated light-emitting pixel bar completely covers the transparent area 12, the translated light-emitting pixel bar sweeps the transparent area 12 within the persistence of vision time interval and the partial picture corresponding to the transparent area 12 is displayed synchronously. Fig. 3 shows the translation of the translation-type light-emitting pixel strip in the left-right direction, and fig. 4 shows the translation of the translation-type light-emitting pixel strip in the up-down direction. The translational light-emitting pixel strips can be driven by the micro motor to move periodically, and optionally, the translational light-emitting pixel strips keep moving at a constant speed when passing through the transparent area 12. The movement track is disposed at a position not to shield the camera module 2, such as at the edge of the transparent area 12 or at the outer side area. The pixels on the translating light-emitting pixel strip that need to be illuminated can be relatively fixed while sweeping through the entire transparent area to display a picture.
As shown in fig. 5 to 8, fig. 5 to 8 are schematic diagrams of the working principle of the display device according to different embodiments of the present invention. In such embodiments, the fast moving display device includes a microdisplay 42 whose display area may cover the transparent region 12. Optionally, the fast moving display device 4 comprises an OLED micro display or a micro led micro display. In practical application, the display parameters such as brightness, chromaticity or pixel density of the OLED micro display screen or the micro led micro display screen are as consistent as possible with the corresponding display parameters of the display screen 1 in the main display area 11, so as to further improve the display effect of the full-screen.
When the display screen 1 is used for displaying a picture in a full screen, the micro display screen 42 moves to be overlapped with the transparent area 12 and synchronously displays a complete picture corresponding to the transparent area 12, and the complete picture displayed by the micro display screen 42 is positioned on the same plane with a picture displayed by the main display area 11 after passing through the micro optical element 3. Compared with the embodiments corresponding to fig. 2 to 4, the embodiments described in fig. 5 to 8 do not need to use the persistence of vision effect, and the display frame of the micro display 42 can completely map the transparent region 12. When the camera module 2 is in the front shooting mode, the micro display screen 42 moves out of the transparent area 12 and stops at a position not covering the camera module 2, and the camera module 2 shoots images through the micro optical element 3.
As shown in fig. 5 and 6, the fast moving display device 4 may include a rotating microdisplay 42. When the display screen 1 is used for displaying a picture in full screen, the display area of the rotary micro display screen completely covers the transparent area 12, i.e. the rotary micro display screen is located right behind the transparent area 12. When the camera module 2 is in the front shooting mode, the rotary micro display screen is moved away from the transparent area 12 through self-turning or curve translation. Fig. 5 shows the rotational microdisplay flipped around its right side edge, and in various embodiments the rotational microdisplay flips itself around either side edge. Fig. 6 shows that the rotational micro-display is curved around its adjacent rotation axis 421, and the rotation axis 421 can be set at a position where the camera module is not shielded, such as at the edge or outside area of the transparent region 12. It should be noted that the position of the rotary micro display screen can be changed between the position right behind the transparent region 12 and the position not covering the camera module 2, and the invention is not limited by the angle and direction of rotation.
As shown in fig. 7 and 8, the fast moving display device 4 may include a translating microdisplay 42. When the display screen 1 is used for displaying a picture in a full screen, the display area of the translational miniature display screen completely covers the transparent area 12, i.e. the translational miniature display screen is located right behind the transparent area 12. When the camera module 2 is in the front shooting mode, the translational micro display screen is moved away from the transparent area 12 by linear translation. Fig. 7 shows the translational micro display screen translating left and right, and fig. 8 shows the translational micro display screen translating up and down. The translation type micro display screen can move along the guide rail 422, and the rail 422 is arranged at the position where the camera module is not shielded, such as the edge or the outer area of the transparent area 12.
In the above different embodiments, the same reference numbers are used for the elements with the same or similar functions, but it should be noted that the same reference numbers do not indicate that the elements referred to by the same reference numbers are necessarily identical in each embodiment.
Alternatively, when the display apparatus 100 is in the standby mode, the fast moving display device 4 stops moving and stops at a position where it does not block the camera module 2. The standby mode includes displaying a picture without using both the main display area 11 and the transparent area 12 of the display 1, or at least without displaying a picture within the range of the transparent area 12.
Optionally, the micro-optical element 3 is integrated in the transparent region 12 at a position opposite to the camera module 2. Within the range that the transparent area 12 faces the camera module 2, no patterning process can be performed on the corresponding display substrate, so as to improve the light transmittance.
Optionally, the micro-optical element 3 is an optical lens. The optical axis direction of the lens of the micro-optical element 3 coincides with the optical axis direction of the lens of the camera module 2.
Optionally, the main display region 11 is a high resolution display region and the transparent region 12 is an optically transparent region. The display panel 1 may be an AMOLED (active matrix organic light emitting diode) display panel, but the invention is not limited thereto. The display screen 1 is provided with pixel units and various routing lines in the main display area 11, and no pixel units or only transparent routing lines are arranged in the transparent area 12. The orthographic projection area of the camera module 2 on the transparent area 12 is not more than the area of the transparent area 12.
Alternatively, the pixel density of the fast moving display device 4 corresponds to the pixel density of the display screen 1 in the main display area 11. The display area of the fast moving display device 4 and the main display area 11 of the display screen 1 both have a pixel density with a high PPI.
In the control method of the display device according to an embodiment of the present invention, the display device includes a display screen and a camera module, the display screen has a main display area and a transparent area that are adjacent to each other, and the camera module is disposed on a non-display side of the display screen and corresponds to the transparent area in position. The display device further comprises a micro optical element and a fast moving type display device, the micro optical element is arranged in the transparent area, the position of the micro optical element corresponds to the camera module, and the fast moving type display device is arranged between the micro optical element and the camera module. The control method of the invention comprises the following steps: when the display screen is used for displaying a picture in a full screen mode, the fast moving type display equipment is controlled to move to the transparent area and synchronously display the picture corresponding to the transparent area, and the picture displayed by the fast moving type display equipment is positioned on the same plane with the picture displayed by the main display area after passing through the micro optical element. When the camera module is in the front shooting mode, the quick moving type display equipment is controlled to move out of the transparent area and stop at a position where the camera module is not shielded, and the camera module shoots images through the micro optical element.
In one embodiment, a fast moving display device includes light-emitting pixel bars having a display area smaller than a transparent region. When the display screen is used for displaying a picture on the full screen, the light-emitting pixel bars are controlled to sweep through the transparent area within the visual persistence time interval and synchronously display a local picture corresponding to the transparent area, and the local picture displayed by the light-emitting pixel bars is imaged by the micro optical elements and then is positioned on the same plane with the picture displayed by the main display area. When the camera module is in the leading shooting mode, control luminous pixel strip stop motion and stop in the position that does not shelter from the camera module, the camera module sees through miniature optical element and shoots the image. Optionally, the control method of the present invention further includes: when the display device is in a standby mode, the light-emitting pixel strips are controlled to stop moving and stop at a position where the camera module is not shielded.
In one embodiment, a fast moving display device includes a miniature display screen with a display area that can cover a transparent region. When the display screen is used for displaying a picture in a full screen mode, the micro display screen is controlled to move to be overlapped with the transparent area and synchronously display a complete picture corresponding to the transparent area, and the complete picture displayed by the micro display screen is positioned on the same plane with the picture displayed by the main display area after passing through the micro optical element. When the camera module is in the leading mode of shooing, control miniature display screen and shift out the transparent area and park in the position that does not shelter from the camera module, the camera module sees through miniature optical element and shoots the image.
